Broccoli Gratin

by Melissa on December 7, 2010

Every Thanksgiving, I like to try one or two new side dishes. We always have the traditional mashed potatoes and gravy, stuffing and rolls, but when it comes to the vegetables, I like mix it up a bit. This year I made this wonderful broccoli gratin. I really had no doubt that this recipe would be delicious and I didn’t even make a test run before the big day.

This recipe takes the classic broccoli and cheese sauce to a whole new level. Freshly steamed broccoli is layered with a rich and creamy white sauce and sharp cheddar cheese, then topped with fresh bread crumbs toasted in butter. Can you see why I knew this would be delicious?

Broccoli Gratin

  • 1/4 cup unsalted butter, plus more for the baking dish
  • 3 tablespoons all-purpose flour
  • 1 1/2 cups whole milk
  • 1 1/2 teaspoons kosher salt, plus more as needed
  • Freshly ground black pepper
  • 2 pounds broccoli (about 4 heads), cut into small florets (about 8 cups)
  • 1.5 cups freshly grated sharp Cheddar 
  • 1/2 cup fresh bread crumbs

Place a rack in the middle of the oven and preheat to 450 degrees F. Butter an 8-by-8-by-2-inch baking dish or an 8-cup gratin dish.

Melt 3 tablespoons of the butter in a medium saucepan over medium heat. Whisk in the flour until smooth. Cook, stirring, for 1 minute. Add the milk, 1 teaspoon salt and bring to a boil while whisking constantly. Lower the heat and simmer, stirring occasionally, until the white sauce is thickened, about 10 minutes. Season with pepper. Remove from the heat.

Meanwhile, bring about 1-inch of water to a boil in a large saucepan and set up a collapsible steamer on top. Put the broccoli in the steamer and season with salt. Cover, and steam until crisp-tender, about 5 minutes. Put the broccoli in the prepared dish, sprinkle with half of the cheese and pour on the sauce. Cover with the remaining cheese.

Melt the remaining 1 tablespoon butter in a medium skillet over medium-high heat. Add the bread crumbs and cook, stirring, until lightly browned, about 2 minutes. Cover the gratin with the bread crumbs. Bake until lightly browned and bubbly, about 20 minutes. Serve immediately.

That sounds great! Broccoli is one of very few veggies my husband will eat so the more ways I can prepare it the better!

Just discovered your page, Melissa, after googling how to pipe Nutella (no secrets). Have you ever tried this recipe with skim or 1 % milk and how did it turn out? One and a half cups of whole milk is hard for me to accept! Thanks.

I have not tried it with skim or 1% milk. I think 1% would be ok, or a mixture of whole and skim/1%, but I would not try all skim! :)
