Haitian-Inspired Shrimp Linguine with Uni Butter
There are times when a familiar dish becomes the starting point for something completely new. This Haitian-Inspired Shrimp Linguine with Uni Butter is one of those recipes.
The foundation is unmistakably influenced by the flavors I use in Haitian cooking: shrimp seasoned with Haitian epis, garlic, scallions, fresh tomatoes, and a little heat and warmth from paprika. But instead of making traditional Haitian spaghetti, I take the dish in a different direction with linguine and homemade uni butter, or sea urchin butter.
The result is a fresh tomato pasta that is savory and rich without needing a heavy sauce. The tomatoes provide brightness and acidity, the epis season the shrimp, and the uni butter melts into the sauce, adding an extra layer of umami.
It’s Caribbean flavor meeting a little culinary experimentation—and that’s exactly what makes this pasta interesting.
This is Haitian-inspired, not traditional Haitian spaghetti
Before we get into the recipe, there’s an important distinction to make.
This is not traditional Haitian spaghetti (espageti).
Traditional Haitian spaghetti has its own identity, history, ingredients, and place in Haitian food culture. If you’re learning about the dish for the first time, start with my Haitian Spaghetti (Espageti) Guide, where I explain how Haitians prepare and serve spaghetti and how it differs from Italian-style pasta dishes.
This shrimp linguine is instead a modern recipe inspired by Haitian flavor-building techniques. Haitian epis season the shrimp. Garlic, scallions, and peppers reinforce those familiar aromatics. Fresh tomatoes create the sauce. Then uni butter introduces something different: the rich, briny umami of sea urchin.
That distinction allows us to respect the traditional dish while still having some fun in the kitchen.
Why you’ll love this shrimp linguine
There is a lot of flavor here without an excessively long ingredient list.
Fresh tomatoes create the sauce. Instead of relying on jarred pasta sauce, crushed ripe tomatoes are cooked down with garlic and scallions.
Haitian epis does the heavy lifting. A relatively small amount brings herbs, aromatics, acidity, and seasoning to the shrimp.
Uni butter adds richness and umami. It melts into the tomato sauce much like a finishing butter, adding depth without requiring cream.
Linguine holds the sauce beautifully. Its wider shape gives the tomatoes and butter more surface area to cling to.
And most importantly, the shrimp still tastes like shrimp. The uni is there to enhance the seafood flavor, not bury everything underneath it.
What is uni butter?
Uni is the edible portion of a sea urchin. Its flavor can range from mildly sweet and creamy to distinctly briny and oceanic, depending on the variety, freshness, and where it was harvested. When uni is combined with butter and aromatics, you get uni butter, a compound butter with an intensely savory seafood character.
For this recipe, I use my homemade uni butter made with unsalted butter, fresh sea urchin, garlic, shallot, parsley, thyme, hot pepper, and a touch of lemon juice.
If you’ve never cooked with sea urchin before, read my Sea Urchin (Uni) Guide first. It explains what uni is, what it tastes like, how it is used, and its connection to Caribbean food traditions.
Then head to my How to Make Uni Butter recipe to prepare the butter used here.
The Haitian flavor connection
One of my goals when developing recipes is to show that Haitian ingredients and cooking techniques don’t have to remain confined to a small group of familiar dishes.
Haitian epis is a perfect example. Epis is an aromatic seasoning base typically made with fresh herbs, peppers, garlic, onions or scallions, citrus or vinegar, and other seasonings. Recipes vary from household to household.
Here, I’m not adding epis directly to the tomato sauce. Instead, I use it to season the shrimp. That matters.
The shrimp gets the concentrated flavor of the epis while the tomato sauce remains relatively simple. When everything is combined at the end, the seasoned shrimp brings those flavors into the rest of the dish without turning the sauce into another epis-based preparation.
It’s a simple technique you can use beyond this recipe when cooking fish, shrimp, chicken, vegetables, and other proteins.
Why fresh crushed tomatoes work so well
Fresh tomatoes give this pasta a completely different personality from a heavier cooked tomato sauce.
Crushing the tomatoes releases their juices and pulp while maintaining some texture. Once they hit the skillet with garlic, scallions, and olive oil, they begin to break down and concentrate. You don’t need to cook them for an hour.
The goal isn’t a thick Italian-American red sauce. You want the tomatoes to remain fresh-tasting while reducing enough to coat the linguine. Then the uni butter changes the texture again.
As the butter melts into the tomato juices, it helps create a glossy sauce that feels richer than the ingredient list suggests.
Choose ripe tomatoes
Because the sauce has so few ingredients, tomato quality matters. Use ripe tomatoes that smell like tomatoes and have some natural sweetness. Very firm, underripe tomatoes can leave the sauce watery and overly acidic.
If your tomatoes release a lot of liquid, simply give them a few extra minutes in the skillet before adding the uni butter.
Why I use linguine
I’ve said this before when talking about Haitian spaghetti: pasta shape matters.
For this particular recipe, linguine is one of my favorite choices. Its flat, slightly wider strands give the crushed tomatoes and uni butter something to cling to. It also has enough body to hold up when tossed with the shrimp.
Fettuccine would also work if you want an even wider noodle.
I would avoid angel hair or very thin spaghetti. The delicate pasta can quickly become too soft once tossed with tomatoes, butter, and shrimp. Whatever pasta you choose, cook it only until al dente.
Seasoning the shrimp with Haitian epis
Start by patting the shrimp dry. This small step is important because overly wet shrimp will steam rather than develop flavor when they hit the hot skillet.
Season the shrimp with Haitian epis and paprika, and let them sit briefly while you prepare the other ingredients.
You don’t need a long marinade. Shrimp is delicate, and if your epis contains citrus juice or vinegar, leaving raw shrimp in it for too long can begin to change its texture.
Cook the shrimp quickly and remove them from the skillet before making the sauce. Don’t wait for them to become hard and tightly curled. They’ll go back into the hot pasta later and finish cooking then.
Don’t waste what’s left in the skillet
After removing the shrimp, you’ll probably see browned bits of epis and seasoning left behind. That’s flavor.
Add the garlic and scallions to the same skillet, followed by your crushed tomatoes. As the tomatoes release their juices, scrape the bottom of the pan. Those little bits become part of the sauce, connecting the seasoned shrimp to the tomatoes.
It’s one of the easiest ways to build flavor without adding more ingredients.
How much uni butter should you use?
Start conservatively. I recommend beginning with about 2 tablespoons of uni butter and tasting the sauce before adding more.
Uni can vary considerably in intensity. Your homemade butter can also be stronger or milder depending on how much sea urchin you used.
You want to taste that extra savory seafood character, but the sauce should still taste like fresh tomato, garlic, scallions, shrimp, and herbs. If uni is the only thing you can taste, you’ve probably gone too far.
Pasta water is part of the sauce
Before draining your linguine, scoop out about a cup of the cooking water. You may not need all of it; in fact, you probably won’t. But a few tablespoons can make a big difference.
The starch released by the pasta helps the tomato juices, olive oil, and butter come together and cling to the linguine.
Add it gradually while tossing the pasta. You’re looking for a glossy sauce that coats the noodles, not a pool of liquid at the bottom of your skillet.
Be careful with additional salt
Taste first. There are several sources of seasoning in this dish:
- Salted pasta water
- Haitian epis
- Seasoned shrimp
- Uni butter – if you used salted butter or added salt to the mixture.
Depending on how you’ve prepared your epis and uni butter, you may need very little additional salt.
This is one reason I prefer making compound butter with unsalted butter. It gives you much more control over the final seasoning.
What to serve with shrimp linguine
Because the pasta is already rich and savory, keep the sides relatively simple.
A crisp green salad with a bright citrus vinaigrette works beautifully. You could also serve it with steamed vegetables, sautéed leafy greens, roasted vegetables, or avocado on the side.
For something very simple, serve the linguine as the main dish with a salad and let the pasta do the talking.
Can you make it without uni butter?
Yes. You won’t get the same depth or distinctive seafood umami, but you can still make an excellent Haitian-inspired shrimp linguine. Use unsalted butter instead and consider adding a little more garlic, herbs, or scallions.
If you enjoy seafood flavors, however, I’d make the uni butter at least once before substituting it. It’s what gives this particular recipe its personality.
Tips for the best Haitian-Inspired Shrimp Linguine
Cook your pasta al dente. It will continue cooking slightly when tossed with the hot sauce.
Don’t overcook the shrimp. Remove them from the skillet as soon as they’re almost cooked.
Use good tomatoes. This isn’t the recipe for pale, flavorless tomatoes.
Keep the garlic from burning. Garlic needs only a short time in the skillet before you add the tomatoes.
Lower the heat before adding uni butter. Think of it as a finishing ingredient rather than something that needs aggressive cooking.
Add uni butter gradually. You can always add more. You can’t take it back out.
Save your pasta water. That cloudy water is one of the ingredients that turns everything into a cohesive sauce.
Frequently Asked Questions
What does uni butter taste like in pasta?
Uni butter adds richness, umami, and a subtle briny seafood flavor. Combined with shrimp and tomatoes, it intensifies the seafood character without needing cream or a heavy sauce.
Can I use spaghetti instead of linguine?
Yes. Regular spaghetti works, but I prefer linguine because its wider surface holds the fresh tomato and uni butter sauce particularly well. Avoid very thin spaghetti or angel hair.
Can I use frozen shrimp?
Absolutely. Thaw the shrimp completely, drain them well, and pat them dry before seasoning them with Haitian epis.
Can I prepare the uni butter ahead?
Yes. That’s actually one of the advantages of making compound butter. Prepare the uni butter separately and store it appropriately until you’re ready to make the pasta.
Is this traditional Haitian food?
No. This is a Haitian-inspired recipe that uses Haitian epis and Haitian flavor-building techniques alongside fresh tomatoes, shrimp, linguine, and uni butter. For the traditional dish, see my Haitian Spaghetti Guide and Haitian Spaghetti recipe.
A different way to cook with Haitian flavors
Traditional recipes deserve to be documented and preserved accurately. But understanding a cuisine also means understanding how its flavors work.
Once you understand why epis works, how fresh aromatics are layered, how seafood is seasoned, and how ingredients balance one another, those techniques can become the foundation for new dishes. That’s what happened with this linguine.
Fresh tomatoes keep the sauce bright. Haitian epis gives the shrimp its aromatic character. Uni butter brings an unexpected layer of savory richness. And linguine ties everything together.
It isn’t traditional Haitian spaghetti, and it isn’t trying to be. It’s simply another delicious way to bring Haitian flavors into the kitchen.

Ingredients
For the Shrimp
- 1½ pounds large or extra-large shrimp peeled and deveined
- 2 tablespoons Haitian epis
- 1 teaspoon paprika
- ½ teaspoon freshly ground black pepper optional
- 1 tablespoon olive oil
For the Linguine and Fresh Tomato Sauce
- 1 pound 16 ounces linguine
- Salt for the pasta cooking water
- 2 tablespoons olive oil
- 4 garlic cloves minced
- 4 scallions sliced
- 3 cups fresh crushed tomatoes
- 3 tablespoons uni butter – Haitian inspired recipe plus more to taste
- ½ teaspoon freshly ground black pepper or to taste
- Salt only if needed
- ½ –1 cup reserved pasta water as needed
Instructions
Season the shrimp
- Pat the shrimp dry with paper towels and place them in a large bowl. Add the Haitian epis, paprika, and black pepper, if using. Toss until the shrimp are evenly coated. Let them rest for about 10–15 minutes while you prepare the remaining ingredients.
Prepare the fresh tomatoes
- Wash and roughly chop the tomatoes, then crush or pulse them until you have about 3 cups of fresh crushed tomatoes. Keep some texture—you don’t want a completely smooth tomato purée.
Cook the linguine
- Bring a large pot of water to a boil and season it with salt. Add the linguine and cook according to the package directions until al dente.
- Before draining, reserve about 1 cup of the pasta cooking water. Drain the linguine and set aside. Do not rinse the pasta.
Cook the shrimp
- While the pasta cooks, heat 1 tablespoon olive oil in a large, deep skillet over medium-high heat.
- Add the seasoned shrimp in a single layer, working in batches if necessary to avoid overcrowding the pan. Cook for about 1–2 minutes per side, or until the shrimp are almost cooked through.
- Transfer the shrimp to a plate and set aside. They will finish cooking when they’re returned to the sauce.
Sauté the garlic and scallions
- Reduce the heat to medium. Add the remaining 2 tablespoons olive oil to the same skillet.
- Add the minced garlic and sliced scallions. Sauté for about 30–60 seconds, stirring frequently, just until fragrant. Don’t allow the garlic to burn.
Make the fresh tomato sauce
- Pour the fresh crushed tomatoes into the skillet. Stir well, scraping the bottom of the pan to incorporate the flavorful bits left from cooking the shrimp.
- Bring to a gentle simmer and cook for about 8–12 minutes, stirring occasionally, until the tomatoes have softened and some of their excess liquid has evaporated.
- The sauce should still taste fresh and have some texture rather than becoming extremely thick.
Add the uni butter
- Reduce the heat to low. Add 3 tablespoons uni butter and gently stir until it has completely melted into the tomato sauce.
- Taste the sauce. Add another tablespoon of uni butter if you want a more pronounced uni flavor.
- Avoid boiling the sauce aggressively after adding the uni butter.
Toss the linguine with the sauce
- Add the drained linguine directly to the skillet and toss until the pasta is thoroughly coated.
- Add reserved pasta water a few tablespoons at a time, as needed. Continue tossing until the tomato sauce and uni butter create a light, glossy sauce that clings to the linguine.
Return the shrimp
- Add the cooked shrimp and any juices from the plate back to the skillet.
- Gently toss everything together over low heat for 1–2 minutes, just until the shrimp are heated through and completely cooked.
Taste and serve
- Taste before adding additional salt. The salted pasta water, Haitian epis, and uni butter already contribute seasoning, so you may not need much—or any—additional salt.
- Add freshly ground black pepper if desired and serve the Haitian-Inspired Shrimp Linguine with Uni Butter immediately.
Notes
- Don’t overcook the shrimp. Cook them just until they turn opaque, remove them from the pan, and return them toward the end.
- Fresh tomatoes matter here. Because this is a relatively simple sauce, ripe, flavorful tomatoes will yield noticeably better results than watery or underripe tomatoes.
- Add the uni butter over lower heat. You don’t need to cook it aggressively. You’re using it almost like a finishing butter, letting it melt into the tomato sauce to add richness.
- Start with less uni butter. Uni has a concentrated savory, ocean-like flavor. Two tablespoons may be enough depending on the strength of your homemade batch.
- Reserve your pasta water. The starch in the water helps emulsify the olive oil, tomatoes, and uni butter, creating a sauce that coats the linguine rather than sitting at the bottom of the pan.
Why linguine works particularly well
Linguine is a very good choice for this recipe. It has more surface area than thin spaghetti, so the fresh tomato sauce and melted uni butter cling to it better. It also has enough structure to withstand the shrimp without becoming soft or pasty when everything is tossed together. I would not use angel hair or very thin spaghetti here. Between the crushed tomatoes, epis-seasoned shrimp, and butter, the dish needs a pasta with some body.What the uni butter does
The uni butter shouldn’t make this taste like “sea urchin pasta” too strongly. It functions more like a concentrated flavor enhancer. The sea urchin brings natural umami and a subtle oceanic quality, while the butter rounds out the acidity of the fresh tomatoes. Combined with garlic, scallions, Haitian epis, and shrimp, it creates a sauce that tastes much more complex than the short ingredient list suggests.Nutrition
