What Kind of Lobster Should I Use?

For best results, choose live lobsters or freshly cooked lobster tails. Maine lobsters are favored for their sweet, tender meat, but spiny lobsters work well too. If using frozen lobster tails, be sure to thaw them completely before cooking to retain texture and flavor. The fresher the lobster, the more decadent the dish.

How To Make the Lobster Thermidor

Step 1: Prepare the Lobster

Boil the live lobsters in salted water for about 8–10 minutes, or until they turn bright red. Remove, cool slightly, and split them in half lengthwise. Scoop out the meat, chop it into bite-sized pieces, and reserve the shells for stuffing later.

Step 2: Sauté the Aromatics

In a skillet over medium heat, melt butter and add finely chopped shallots and garlic. Sauté until translucent and fragrant, about 2–3 minutes.

Step 3: Deglaze with Wine

Pour in the white wine and simmer for 3–4 minutes until slightly reduced. This adds depth and acidity to balance the creaminess of the dish.

Step 4: Create the Creamy Base

Stir in heavy cream and Dijon mustard. Let the mixture cook for 5–6 minutes until slightly thickened. In a separate bowl, temper the egg yolks by slowly whisking in a bit of the hot cream mixture, then add the yolks back into the skillet. Stir continuously until smooth and glossy.

Step 5: Fold in the Lobster

Add the chopped lobster meat into the sauce and season with salt, pepper, and a touch of lemon juice if desired. Stir to combine and gently heat through without boiling.

Step 6: Stuff and Top with Cheese

Spoon the creamy lobster mixture back into the empty lobster shells or into a baking dish. Top generously with grated Gruyère or Parmesan cheese.

Step 7: Broil to Perfection

Place the stuffed shells under the broiler for 2–3 minutes until the cheese is golden and bubbly. Garnish with fresh parsley before serving.

How to Serve and Store Lobster Thermidor

Lobster Thermidor is best served immediately after broiling, when the cheese topping is hot and bubbly, and the sauce is still silky smooth. Present it in the lobster shell for a dramatic restaurant-style effect, or in individual ramekins for an elegant dinner party. Pair with a crisp white wine like Chardonnay and sides such as roasted asparagus, buttery mashed potatoes, or a fresh garden salad.

For leftovers, store in an airtight container in the refrigerator for up to 2 days. Reheat gently in a 300°F oven until warmed through. Avoid using the microwave, as it can separate the sauce and make the lobster rubbery.

Frequently Asked Questions

What if I don’t have lobster shells to stuff?

No problem! Use ramekins or a small baking dish to portion and bake the creamy filling.

Can I make this ahead of time?

Yes, you can prepare the lobster filling and stuff the shells a few hours in advance. Refrigerate and broil just before serving.

What can I use instead of white wine?

Chicken or seafood stock with a splash of lemon juice works well as a substitute.

Is it necessary to use egg yolks?

Egg yolks help thicken the sauce and give it a rich texture, but you can skip them if preferred—just simmer the cream a bit longer.

Can I freeze Lobster Thermidor?

It’s not recommended. The cream sauce can separate upon thawing, and lobster tends to lose its tenderness.

What cheese is best for topping?

Gruyère is traditional for its melt and flavor, but Parmesan or a sharp cheddar also works deliciously.
