These seafood stuffed shells are packed with shrimp and lump crab, baked in a creamy Cajun sauce with melty cheese. A restaurant-worthy dinner made at home.
Boil shells just shy of al dente; drain, oil, and cool.
Sauté onion, peppers, and garlic; season. Add chopped shrimp and cook until barely pink. Fold in crab gently; cool and mix with mozzarella and parmesan.
For the sauce: melt butter, sweat shallot and garlic. Add tomato paste and lobster base; cook 1–2 minutes. Deglaze with wine and reduce. Add cream, simmer, stir in parmesan, and season.
Spread sauce in a baking dish, stuff and arrange shells, and spoon sauce over.
Top with cheese and bake at 375°F for 20–25 minutes until bubbly; broil to finish.
Rest, garnish with parsley, and serve.
Notes
Undercook the shells so they don't tear when stuffed. Cook the shrimp only until barely pink; they finish in the oven. Sub stock for wine for an alcohol-free sauce. Assembles ahead well.
