Ingredients You’ll Need
The beauty of this recipe is in its simplicity. Each ingredient is chosen carefully to contribute to the incredible flavor and texture of the strata. From the freshness of the asparagus to the mellow sharpness of the cheese, every bite is well-balanced and satisfying.
- Butter: Used to sauté the mushrooms, it adds richness and helps develop a lovely caramelized flavor.
- Crimini mushrooms (1 ¾ cups sliced): These bring a deep, earthy taste and wonderful texture to the dish.
- English muffins (5, split and toasted): The base of the strata, their slight crunch and absorbent crumb soak up the custard beautifully.
- Colby-Monterey Jack cheese (2 cups shredded, divided): A mellow, creamy cheese that melts effortlessly to tie all the flavors together.
- Fresh asparagus (1 pound, trimmed and cut into 1-inch pieces): Adds freshness, vibrant color, and a lovely earthy bite that contrasts with the richness.
- Red bell pepper (½ cup chopped): Introduces a subtle sweetness and a pop of bright color.
- Onion (½, finely chopped): Provides a gentle depth of savory flavor without overpowering.
- Milk (2 cups): Forms the custard’s creamy base.
- Eggs (8): The binding agent that sets the strata into a satisfying casserole.
- Salt (1 teaspoon): Enhances every flavor in the dish.
- Ground black pepper (¼ teaspoon): Adds a touch of spice and warmth.
How to Make Overnight Asparagus Mushroom Strata Recipe
Step 1: Sauté the Vegetables
Start by melting butter in a skillet over medium heat, then add the sliced crimini mushrooms. Cook them gently until they begin to brown and most of their liquid evaporates—this usually takes about 10 minutes. This step is crucial because it intensifies the mushrooms’ flavor and prevents your strata from becoming soggy later on. Adding the red bell pepper and finely chopped onion at this stage lets their sweetness mellow and blend beautifully with the earthiness of the mushrooms.
Step 2: Prepare the Baking Dish
Next, grease a 9×13-inch baking dish to prevent sticking. Arrange eight toasted English muffin halves in the dish with the cut-side facing up. Don’t worry if you have some gaps—tear the remaining muffins into smaller pieces and nestle them in to fill any spaces. These muffins soak up the egg custard as the strata bakes, creating an irresistibly soft yet textured base.
Step 3: Layer the Ingredients
Sprinkle half of the shredded Colby-Monterey Jack cheese over the muffin base. Then, layer on the sautéed mushroom mixture alongside the vibrant asparagus pieces. The asparagus adds a pleasant bite and fresh earthiness that balances the richness of the cheese and eggs. Make sure to distribute everything evenly for the perfect flavor balance in every slice.
Step 4: Prepare the Egg Mixture
In a sizable bowl, whisk together the eggs, milk, salt, and black pepper until smooth and combined. This creamy custard is the magic that brings your strata together, soaking into the muffins and veggies to create a custardy, melt-in-your-mouth texture.
Step 5: Refrigerate Overnight
Pour the egg mixture evenly over the layered ingredients in your baking dish. Cover the dish tightly with plastic wrap or aluminum foil to keep it fresh. Then refrigerate for at least 8 hours or overnight. This resting period allows the muffins to soak up all the flavors, making your strata incredibly tender and flavorful.
Step 6: Bake to Perfection
In the morning, take the casserole out of the fridge and let it stand at room temperature for about 30 minutes. This helps ensure even baking. Preheat your oven to 375°F (190°C). Sprinkle the remaining shredded cheese generously over the top, then bake the strata uncovered for 40 to 45 minutes. You’re looking for the top to be golden and a knife inserted near the edges to come out clean. Let it rest for 5 to 10 minutes before slicing to let everything set beautifully.
How to Serve Overnight Asparagus Mushroom Strata Recipe
Garnishes
You can easily elevate this dish with some fresh garnishes. A sprinkle of chopped fresh herbs such as parsley or chives adds a burst of color and a fresh brightness that contrasts nicely with the rich custard. For a touch of indulgence, a dollop of sour cream or a light drizzle of hollandaise sauce brings lovely creaminess that makes the dish feel extra special.
Side Dishes
This strata works wonderfully as a central brunch star alongside fresh fruit salad or lightly dressed greens. The contrast of the warm, savory casserole with the crisp, cool sweetness of fruit or the peppery crunch of greens rounds out the meal beautifully without overwhelming the palate.
Creative Ways to Present
For a festive brunch, consider serving the strata in individual ramekins or muffin tins, making perfect portable portions for guests. You can also cut the strata into fun shapes using cookie cutters to add a playful touch to your brunch table. Pair it with a fresh mimosa or a well-brewed coffee for a truly inviting experience.
Make Ahead and Storage
Storing Leftovers
Leftovers of this strata store wonderfully refrigerated in an airtight container for up to 3-4 days. The flavors actually deepen over time, making for delicious next-day breakfasts or snacks. To keep it fresh, cover tightly to prevent it from drying out.
Freezing
If you want to save some for later, this strata freezes beautifully. After baking and cooling completely, wrap individual portions tightly in plastic wrap and then foil before placing them in a freezer-safe container. It will keep well for up to 2 months, ensuring you have a tasty, quick meal ready to go whenever you want.
Reheating
Reheat your leftover or frozen strata in the oven at 350°F (175°C) until warmed through, usually about 15-20 minutes for refrigerated portions and a bit longer if frozen. You can cover it loosely with foil to prevent the top from browning too much while the inside heats evenly. This method keeps the texture wonderful—warm, custardy, and savory.
FAQs
Can I use bread other than English muffins?
Absolutely! While English muffins provide a nice texture and soak up the custard beautifully, sturdy breads like sourdough or French bread work just as well. Just be sure to toast or dry them slightly to avoid sogginess.
Is it possible to make this recipe vegetarian?
Yes! This recipe is already vegetarian-friendly since it contains no meat. For added protein, feel free to add vegetarian sausage or tofu crumbles, or keep it as is for a delicious vegetable-packed meal.
Can I prepare this strata right before baking instead of overnight?
While you can bake it immediately after assembling, allowing it to rest overnight improves the texture and depth of flavor significantly. The resting period lets the custard soak the bread, making the strata more custardy and tender.
What can I substitute for Colby-Monterey Jack cheese?
If you don’t have Colby-Monterey Jack, other mild melting cheeses like mozzarella, cheddar, or Gouda work well. Avoid very strong cheeses unless you want to alter the flavor profile.
Can I add other vegetables or herbs?
Definitely! Feel free to customize the strata by adding spinach, kale, zucchini, or fresh herbs like thyme or basil. Just adjust cooking times according to the veggies’ tenderness to keep everything balanced.
