Lobster Thermidor

lobster thermidor tails

Antoine’s in New Orleans has many classic dishes on the menu, but my most memorable is their lobster thermidor. Most restaurants guard recipes zealously, especially when they have been in the family for generations, but Roy F. Guste, Jr. the proprietor published a cookbook.

When planning the menu for my French Creole dinner, this became the second course, representing my homage to Antoine’s.

The Plot Thickens

I bought a copy at a local bookstore with a clear agenda in mind. Our group had a reservation that evening. The menu was entirely French but the cookbook included translations. I was ready to impress at dinner. It was also a gift for my wife, suffering back home in the dead of winter. She collected cookbooks and I hoped she might use it to prepare a tasty creole meal for me.

The Reveal

I waited almost forty years, but never tasted a single dish from that cookbook. Recently, when a trip to New Orleans reignited my desire for creole food I decided to have another taste of lobster thermidor. Since I’m the cook now, there was nothing standing in my way.

Key Elements

To make this you must learn how to make a blonde roux, then use it to make bechamel. It’s one of the five “mother sauces” of French cuisine.

You can make bechamel sauce in advance and that’s a good way to start. Doing so eliminates some of the timing pressure in bringing the dish together. This was my second attempt, the first ending in total disaster. I used that practice to tweak the instructions, to make them easier to understand for cooks like me. This time, it all came together perfectly!

Let’s Make It!

Lobster Substitutes?

If your lobster traps were empty this morning, you can substitute shrimp, or if you have a mudbug farm in your backyard, crawfish tails are wonderful! Print
