Instructions

Sauté Vegetables: Melt butter in a skillet over medium heat. Add sliced mushrooms and cook until they begin to brown and most of their liquid evaporates, about 10 minutes.
Prepare Baking Dish: 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.
Layer Ingredients: Sprinkle half of the shredded cheese over the muffins. Top with sautéed mushrooms, asparagus pieces, red bell pepper, and onion.
Prepare Egg Mixture: In a bowl, whisk together milk, eggs, salt, mustard powder, and black pepper. Pour the mixture evenly over the layered ingredients in the baking dish.
Refrigerate: Cover the dish and refrigerate for 8 hours or overnight.
Bake: The next day, remove the casserole from the refrigerator and let it stand for 30 minutes. Preheat the oven to 375°F (190°C). Spread the remaining cheese over the top. Bake for 40 to 45 minutes, or until a knife inserted near the edge comes out clean. Let stand for 5 to 10 minutes before cutting into squares.

Notes

You can substitute the asparagus with other vegetables like broccoli, zucchini, or spinach.

This recipe can be frozen before baking—just thaw overnight in the refrigerator and bake as usual.
