Asparagus Mushroom Overnight Strata

Follow our step-by-step guide on how to make Asparagus Mushroom Overnight Strata.

1. Step 1

   Begin by melting butter in a skillet over medium heat.

2. Step 2

   Once melted, add sliced mushrooms and sauté, stirring occasionally, until they turn golden brown and most of their moisture evaporates, which should take about 10 minutes.

3. Step 3

   Next, prepare a 9x13-inch baking dish by greasing it generously.

4. Step 4

   Place 8 toasted English muffin halves, cut-side up, in the dish's base.

5. Step 5

   Tear the remaining muffin halves into smaller pieces to fill any gaps.

6. Step 6

   Sprinkle half of the shredded cheese over the muffins, then layer on the sautéed mushrooms, asparagus pieces, chopped red bell pepper, and diced onion.

7. Step 7

   In a separate bowl, whisk together milk, eggs, salt, dry mustard powder, and black pepper until well combined.

8. Step 8

   Pour this creamy mixture evenly over the muffin and vegetable layers.

   Cover the dish and let it chill in the refrigerator for at least 8 hours or overnight, allowing the flavors to meld beautifully.
