Instructions

1 Prepare the lobster meat by ensuring it is fully cooked and cut into bite-sized pieces. Set aside the lobster meat in a bowl, and season it lightly with salt and pepper.
2 In a large skillet or saucepan, melt the unsalted butter (or dairy-free alternative) over medium heat. Add the finely minced shallot and sauté until softened and translucent, about 3-4 minutes, releasing a sweet aroma.
3 Stir in the minced garlic and cook for another minute until fragrant, being careful not to burn it. Pour in the gluten-free white wine and let it simmer for about 2 minutes, allowing the alcohol to evaporate and the flavors to meld.
4 Whisk together the gluten-free heavy cream (or coconut milk), gluten-free stock, and gluten-free Dijon mustard in a small bowl until well combined. This mixture will form the base of your rich sauce.
5 Gradually add the cream mixture to the skillet, stirring constantly. Bring the sauce to a gentle simmer, then reduce the heat to low.
6 In a separate small bowl, whisk the cornstarch or arrowroot starch with 2 tablespoons of cold water until a smooth slurry forms. Slowly pour this slurry into the simmering sauce, stirring continuously until the sauce thickens to a velvety consistency, which should take about 2-3 minutes.
7 Gently fold the prepared lobster meat into the thickened sauce. Allow the lobster to heat through in the sauce for about 5-7 minutes, ensuring it is warmed without overcooking. Stir in the paprika and most of the chopped fresh parsley.
8 Taste the sauce and adjust seasoning with additional salt and pepper if needed. Serve the Lobster Thermidor immediately, garnished with the remaining fresh parsley, over gluten-free pasta, rice, or with crusty gluten-free bread for soaking up the delicious sauce.

Tips & Notes

Fold the cooked lobster into the sauce gently and keep it at a bare simmer. It only needs to warm through, and longer cooking toughens it.
Let the wine reduce by about half before the cream mixture goes in, so the sauce tastes rich rather than sharp.
If you use coconut milk instead of cream, a little extra paprika and Dijon balance its sweetness. Choose a Dijon labeled gluten-free.
