This asparagus strata recipe is one of my mom’s best ideas. It is a colorful make-ahead dish that combines toasted English muffins with layers of cheese, mushrooms, and asparagus. It makes brunch a breeze!

Ingredients
-
2 teaspoons butter, or as needed
-
1 ¾ cups sliced crimini mushrooms
-
5 English muffins, split and toasted
-
2 cups shredded Colby-Monterey Jack cheese, divided
-
1 pound fresh asparagus, trimmed and cut into 1-inch pieces
-
½ cup chopped red bell pepper
-
½ onion, finely chopped
-
2 cups milk
-
8 eggs
-
1 teaspoon salt
-
1 teaspoon dry mustard powder
-
¼ teaspoon ground black pepper
Directions
-
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.
-
Grease a 9×13-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.
-
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.
-
The next day, remove the casserole from the refrigerator and let stand for 30 minutes. Spread remaining cheese over the top.
-
Meanwhile, preheat the oven to 375 degrees F (190 degrees C).
-
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.
Recipe Tips
You can substitute other vegetables for the asparagus, such as broccoli or zucchini.
Add a cup of cooked diced ham or cooked sausage for a non-vegetarian twist.
