Description

This asparagus strata is perfect for a special breakfast or brunch. Best of all, you make it the night before so there's not any hassle in the morning!

Ingredients

2 teaspoons butter, or as needed
1 3/4 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
1/2 cup chopped red bell pepper
1/2 onion, finely chopped
2 cups milk
8 eggs
1 teaspoon salt
1 teaspoon dry mustard powder
1/4 teaspoon ground black pepper

Directions

1 Melt butter in a skillet over medium heat. Add mushrooms; cook and stir until beginning to brown and most of their liquid has evaporated, about 10 minutes.
2 Grease a 9x13-inch baking dish. Arrange eight muffin halves, cut-side up, in the bottom of the dish. Tear remaining muffins into smaller pieces and use to fill any open spaces. Sprinkle with 1/2 of the cheese, then top with asparagus pieces, mushrooms, red pepper, and onion.
3 Whisk milk, eggs, salt, mustard powder, and black pepper together in a bowl; pour over muffins and vegetables. Cover the dish and refrigerate, 8 hours to overnight.
4 The next day, remove the casserole from the refrigerator and let stand for 30 minutes. Spread remaining cheese over the top.
5 Meanwhile, preheat the oven to 375 degrees F (190 degrees C).
6 Bake the casserole in the preheated oven until a knife inserted near the edge comes out clean, 40 to 45 minutes. Let stand for 5 to 10 minutes before cutting into squares.
