1 9x13-inch casserole


  • 2 teaspoons butter, or as needed

  • 1 ¾ cups sliced crimini mushrooms

  • 5 English muffins, split and toasted

  • 1 cup shredded Colby-Monterey Jack cheese

  • 1 pound fresh asparagus, trimmed and cut into 1-inch pieces

  • ½ cup chopped red bell pepper

  • ½ onion, finely chopped

  • 8 eggs

  • 2 cups milk

  • 1 teaspoon salt

  • 1 teaspoon dry mustard powder

  • ¼ teaspoon ground black pepper

  • 1 cup shredded Colby-Monterey Jack cheese


  1. Melt butter in a skillet over medium heat, and cook and stir mushrooms until their liquid has mostly evaporated and mushrooms are beginning to brown, about 10 minutes. Set the mushrooms aside.

  2. Grease a 9x13-inch baking dish, and arrange 8 muffin halves, cut-sides up, in the bottom of the dish. Stuff pieces of remaining muffins into the spaces between halves. Spread 1 cup of Colby-Monterey Jack cheese over muffins in a layer, and distribute asparagus pieces, mushrooms, red pepper, and onion over cheese.

  3. Whisk together eggs, milk, salt, dry mustard, and black pepper in a bowl, and pour egg mixture over muffins and vegetables. Cover the dish, and refrigerate overnight.

  4. The next day, preheat the oven to 375 degrees F (190 degrees C).

  5. Remove casserole from the refrigerator and let stand for 30 minutes. Spread 1 cup of Colby-Monterey Jack cheese in a layer over the casserole.

  6. Bake in the preheated oven until a knife inserted near the edge comes out clean, 40 to 45 minutes. Let stand 5 to 10 minutes before cutting into squares.


Substitute the asparagus with other veggies, such as broccoli or zucchini, or add a cup of cooked diced ham or sausage for a non-vegetarian twist.
