Broccoli and Cheese Casserole

Step 1: For the Topping: Process bread and butter in a food processor until coarsely ground. Set aside.

Step 2: Preheat oven to 400 degrees. Bring 4 quarts of water to a boil in a large pot. Add 1 tablespoon of salt and the broccoli. Cook until bright green and crisp-tender, about 3 minutes. Drain and leave int he colander - set aside.

Step 3: Melt butter in a medium saucepan over medium heat. Stir in the garlic, mustard, and cayenne; cook until fragrant. Add flout and cook stirring constantly, until golden - about 1 minute. Whisk in the broth and milk; bring to a simmer and cook, whisking often, until large bubbles erupt at the surface and the mixture is slightly thickened - about 5 minutes. Off the heat, add cheeses and roasted peppers. Season to taste with salt and pepper.

Step 4: Spread the broccoli in a 9x13" casserole. Pour cheese sauce over the top. Sprinkle with breadcrumb topping. Bake until golden brown and bubbling around the edges - about 15 minutes.
