How to Make Lobster Thermidor
- Preheat the oven to 350°F and prepare the lobster shells. Halve cooked lobsters, clean out meat, chop larger pieces into bite-sized chunks, and set shells aside.
- Saute shallots and garlic: Melt butter in a skillet over medium heat. Add finely chopped shallots and garlic; cook until softened and fragrant, about 2–3 minutes.
- Deglaze: Pour in dry white wine; simmer until reduced by half, about 2 minutes. This bright splash balances the sauce’s creamy richness.
- Create sauce: Stir in Dijon mustard and heavy cream; simmer gently until sauce thickens slightly, about 3–4 minutes, coating the back of a spoon with its velvety texture.

What’s the best way to store leftover Lobster Thermidor?
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Make sure the dish has cooled before sealing to keep that creamy sauce stable and the lobster tender. Reheat gently to avoid drying out the lobster meat.
