Brussels Sprouts Gratin

Need a classic but simple site? Try this Brussels sprouts gratin. Made with blanched sprouts in a rich Gruyere sauce, it’s topped with diced pancetta for an extra flavor boost.

Tick ​​tock, tick tock. Turkey Day is coming, are you ready? Somehow, Thanksgiving just doesn’t seem the same without at least one classic, cheesy gratin.

Baked potatoes or beets are often featured here, and in some years a gratin of fennel was the star.

This year my gratin of choice is a creamy Brussels sprouts gratin, with Brussels sprouts that have been blanched and then baked in a sauce with pancetta, shallots and gruyere.

How to choose Brussels sprouts

The appearance of Brussels sprouts in the markets is a sign of cooler weather and upcoming holidays. When buying, look for compact little heads that are bright green and firm. Weather or not, they are on the stem, they should be heavy for their size and the leaves tightly packed. If possible, avoid yellowed or wrinkled sheets (as this indicates age). All black spots are a sign of fungus.

Smaller ones are more tender and sweet. They are good for cooking whole. Larger ones are easier to work with if you cut them in half, especially since in this recipe we blanch them before baking.

Can this Brussels sprouts dish be vegetarian?

It’s easy to make a vegetarian dish out of this! Just remove the pancetta and add an extra tablespoon of butter. You can also substitute mushrooms, thinly sliced ​​zucchini, or even some thinly sliced ​​carrots (which add some sweetness to the gratin) for the pancetta.

Other cheeses to try in a Brussels sprouts gratin

Here are a few other cheeses to try instead of Gruyere:

  • Gouda cheese
  • Emmental
  • Jarlsberg
  • Raclette
  • Edam
  • Cheddar

The best way to cut the Brussels sprouts is to snip 1/4 inch from the bottom of the stalk with a paring knife. This makes it easier to peel off hard outer sheets. Then, when you cut the Brussels sprouts in half, place them cut-side down on the cutting board to stabilize them.

You can easily make this dish vegetarian by omitting the pancetta in step 2. Just add an extra tablespoon of butter in step 3.

    Add 3 ounces of grated Gruyere cheese to the white sauce and stir until the cheese is melted and incorporated into the sauce. Return half of the cooked pancetta to the sauce. Taste and add more salt if needed.

    Add the Brussels sprouts to the cheese sauce and toss. Place the cheesy Brussels sprouts in the prepared casserole dish or gratin dish. Sprinkle with the remaining pancetta and the remaining 1 ounce grated Gruyere cheese.
