I still remember the first time I tried Lobster Thermidor. I was visiting my grandmother in Crete, and she had prepared this luxurious dish for a special family celebration. The aroma of creamy lobster, rich cheese, and a hint of sherry filled the entire house. I loved how simple ingredients could come together to feel so indulgent. Years later, I wanted to bring that same comfort and elegance into a dish that’s easy to share at home. That’s how I created Lobster Thermidor Stuffed Shells a dish that combines the creamy richness of Thermidor sauce with tender pasta shells, perfect for special dinners or cozy weekend treats.

Step-by-Step Instructions:

- Cook the pasta shells
Bring a large pot of salted water to a boil and cook the jumbo shells until al dente. Drain carefully and set aside to cool slightly. - Prepare the Thermidor sauce
In a medium saucepan, melt butter over medium heat. Add shallots and garlic, sautéing until fragrant (about 2 minutes). Stir in flour and cook for 1 minute, whisking constantly. - Add liquids and seasonings
Slowly pour in milk and white wine while whisking to avoid lumps. Cook until the sauce thickens. Stir in Dijon mustard, paprika, salt, and pepper. Remove from heat and mix in Gruyère and Parmesan cheese until smooth. - Combine lobster with sauce
Gently fold chopped lobster meat into the creamy sauce. Taste and adjust seasoning if needed. - Stuff the shells
Spoon generous amounts of the lobster mixture into each cooked pasta shell, arranging them in a buttered baking dish. - Bake and brown
Preheat your oven to 375°F (190°C). Sprinkle extra Gruyère and Parmesan cheese over the stuffed shells. Bake for 15–20 minutes until the tops are golden and bubbly. - Garnish and serve
Sprinkle with fresh parsley for color and a burst of freshness. Serve hot and enjoy every decadent bite.
