This is the kind of dish that makes people quiet at the table in the best way. Large bell peppers stuffed with a filling of blackened garlic butter shrimp, crawfish boudin, and shredded pepper jack cheese, baked until the peppers are completely tender, and finished with a Parmesan cream sauce built directly in the pan where the shrimp was cooked. The sauce picks up every bit of the rendered butter, garlic, and blackening fond left in the skillet, and those drippings are what turn a standard cream sauce into something deeply savory and distinctly Louisiana.

The crawfish boudin is the ingredient that sets this apart from any standard stuffed pepper recipe. Boudin already carries seasoning, pork fat, rice, and that specific South Louisiana flavor that can’t be replicated with anything else. Combined with the heat of the blackened shrimp and the creamy, slightly spicy melt of the pepper jack, the filling is rich and bold in a way that earns the Parmesan cream sauce poured over the top. This is a company-worthy dinner that comes from a single skillet and a baking dish.

Ingredients Needed to Make Seafood Stuffed Bell Peppers

Two components, both straightforward. Here’s everything you need:

The Peppers and Filling

Large bell peppers (choose the largest you can find with flat bottoms so they stand upright; any color works but red and yellow are sweeter)
Crawfish boudin, removed from casing (the seasoned, rice-and-crawfish filled Louisiana sausage that anchors the entire filling)
Shrimp, peeled and deveined (medium to large; blackened in butter and garlic before going into the filling)
Pepper jack cheese, shredded from a block (melts into the filling and adds a creamy, slightly spicy richness)
Butter (for blackening the shrimp and building the foundation of the cream sauce)
Garlic cloves, minced
Olive oil (for coating the peppers before baking)
Salt and pepper
Breadcrumbs or extra pepper jack for topping, optional

The Parmesan Cream Sauce

Pan drippings from the blackened shrimp (the flavor foundation of the sauce)
Heavy whipping cream (the rich, creamy base)
Parmesan cheese, grated (thickens the sauce slightly and adds a salty, nutty depth)

How to Make Seafood Stuffed Bell Peppers

One skillet, one baking dish, and a result that tastes like serious cooking.

Step 1: Prep and Oil the Peppers

Preheat the oven to 350°F. Slice the tops off each bell pepper and remove the seeds and white veins from the inside. Lightly coat the outside and inside of each pepper with olive oil, which helps them blister and soften evenly in the oven without drying out. Place them upright in a baking dish, using a small piece of foil tucked underneath any pepper that tips to keep it stable during baking.

Step 2: Blacken the Shrimp

Melt the butter in a skillet over medium heat. Add the minced garlic and cook for about 30 seconds until fragrant and just beginning to color. Add the shrimp in a single layer and cook for 2 to 3 minutes per side until they develop a blackened, slightly caramelized exterior and are cooked through. The butter will take on the color and flavor of the seasoning and shrimp fond as it cooks. Remove the shrimp and set aside, leaving every drop of the drippings in the pan.

Step 3: Chop the Shrimp

Transfer the blackened shrimp to a cutting board and chop into roughly quarter-inch bite-size pieces. Chopping rather than leaving them whole distributes the shrimp evenly throughout the filling so every bite of the stuffed pepper has shrimp in it rather than just a few whole pieces.

Step 4: Make the Filling

In a large bowl, combine the chopped blackened shrimp, crawfish boudin removed from its casing, and the shredded pepper jack cheese. Mix everything together until evenly combined. Taste for seasoning before stuffing, keeping in mind that the boudin is already well-seasoned.

Step 5: Stuff and Bake

Pack the seafood filling into each bell pepper generously, pressing it in firmly so the pepper is fully loaded. If desired, top with a layer of breadcrumbs, extra shredded pepper jack, or both for a golden, slightly crunchy top. Cover the baking dish tightly with foil and bake at 350°F for 45 minutes until the peppers are completely fork-tender when pierced through the thickest part of the wall.

Step 6: Make the Cream Sauce

In the final 10 to 15 minutes of baking, make the cream sauce in the same skillet used for the shrimp. Pour the heavy whipping cream into the drippings and bring to a gentle simmer over medium heat, scraping up any browned bits from the bottom of the pan. Whisk in the grated Parmesan cheese and cook, stirring frequently, until the sauce has thickened slightly and the cheese is fully incorporated. Taste and adjust seasoning.

Step 7: Plate and Serve

Place one stuffed pepper on each plate and spoon the Parmesan cream sauce generously over and around the base of the pepper. Serve immediately while the sauce is hot and the filling is still bubbling.

Storing and Reheating

Store leftover stuffed peppers in an airtight container in the refrigerator for up to 3 days. Store the cream sauce separately since it can make the peppers soggy if they sit together overnight. To reheat, place the peppers in a 325°F oven covered loosely with foil for 15 to 20 minutes until heated through, then reheat the cream sauce gently in a small saucepan over medium-low heat with a splash of cream to loosen it back to the right consistency.

How to Serve Seafood Stuffed Bell Peppers

These peppers are a complete, restaurant-quality dinner on their own. Plate each pepper individually with a generous ladle of the Parmesan cream sauce over the top and a sprinkle of fresh parsley or green onion for color. A wedge of crusty French bread alongside for soaking up the cream sauce is essentially required and makes the plate feel complete.

For a full Louisiana dinner spread, serve alongside dirty rice, steamed white rice, or a simple green salad with a sharp vinaigrette to cut through the richness of the cream sauce. The peppers are rich enough that a light, acidic side is the best companion rather than something equally heavy.

Frequently Asked Questions About Seafood Stuffed Bell Peppers

What is crawfish boudin?

Boudin is a Cajun sausage made from pork, pork liver, rice, onions, and seasonings stuffed into a natural casing. Crawfish boudin substitutes or combines crawfish with the pork for a seafood-forward version that is deeply seasoned and carries the characteristic South Louisiana flavor profile. It’s sold at most Louisiana butcher shops, grocery stores, and gas stations throughout the state and is available online from Louisiana purveyors. If you can’t find crawfish boudin specifically, regular pork boudin or a mix of cooked crawfish tails with cooked seasoned rice is the closest substitute.

Can I use a different cheese besides pepper jack?

Yes. Pepper jack is recommended for its melt and its mild heat that complements the blackened shrimp and boudin. Colby Jack is a milder alternative with excellent melt. Sharp white cheddar adds a more assertive, tangy flavor. Gruyere is a more elevated option with a nutty richness. Whatever you use, shred it fresh from a block for the best melt rather than using pre-shredded which contains anti-caking agents.

What color bell pepper should I use?

Any color works and the choice comes down to flavor preference. Red, orange, and yellow peppers are sweeter and riper than green, which makes them a natural counterpart to the savory, spiced filling. Green peppers have a more assertive, slightly bitter flavor that also pairs well with Cajun seasoning. A mix of colors in the baking dish looks beautiful on the table and gives guests options.
