What is a Strata?

The word strata is derived from Latin and it means layers. A breakfast strata is a layered casserole with a crusty top and tender, airy interior created by the use of one single ingredient… bread. The bread serves as a base to absorb the eggs and dairy. It’s a bit like a savory bread pudding.

Here’s why this breakfast strata recipe makes a great morning meal:

  • Makes a big casserole that easily serves 10 to 12 people.
  • Only a few minutes of prep time!
  • Looks extremely appetizing with its crisp golden craggy top.
  • The pillowy texture of each bite is wonderfully divine! You get crunch, creaminess, and cheesiness.
  • No pre-cooking anything.
  • Totally customizable. Use different cheeses and add any leftovers or cooked veggies of your choice.

Strata is done when it doesn’t jiggle in the center when you shake it or when a toothpick comes out clean. Try to avoid overcooking the strata, or it will become dry.

Recipe Variations

The basics of breakfast strata are bread, eggs, milk, and cheese. However, you can make it your own with different fillings. You can put almost anything into strata, and it’s great for using up leftovers.

Here are some ideas for add-ins and flavor options:

  • Vegetables: Add asparagus, bell peppers, spinach, mushrooms, broccoli, kale, or zucchini. Try to stick to a total of 3 to 4 cups of vegetables. Cook the vegetables first with some onion and garlic for added flavor.
  • Meat: Sausage for breakfast strata with sausage. Diced bacon for breakfast strata with bacon. You can also go with ground chicken, turkey, or beef. Mix your choice of pre-cooked meat with your chosen cooked vegetables before layering it into the dish.
  • Cheese: Use whatever cheeses are your favorites – sharp cheddar, smoked gouda, pepper jack, fontina, feta, or parmesan. Try combining sharp cheddar and smoked gouda and add scallions and roasted red peppers – yummy!
  • Herbs: Add some fresh or dried herbs to the egg custard – basil, rosemary, thyme.
  • Spices: Add nutmeg or paprika for some extra flavor.
  • Vegetarian: Omit meat for a vegetarian breakfast strata recipe (with egg).
  • Vegan: Here’s a recipe for completely vegan breakfast strata.
  • Special Diets: Use gluten-free bread if you have a gluten-restricted diet. Also, this strata recipe should work fine with non-dairy milk.
  • Sweet: For sweet breakfast strata, skip the cheese and add berries or bananas for the filling and a splash of vanilla.

Breakfast Strata Frequently Asked Questions

Does a strata have to sit overnight?

You do need to allow some time for the bread to soak up the eggs. As a general rule, strata needs to rest for at least one hour before baking.

How long can a strata be allowed to rest?

Strata can rest for up to 18 hours, making it the perfect breakfast casserole to make the night before a big family event.

What is the best type of bread to use?

Any kind of bread will work with this strata recipe, and anything goes, including crusts or no crusts.

Can you use stale bread?

The bread needs to be fully saturated with liquid, and this process is faster with fresh bread. However, you can certainly repurpose stale bread.

What to Serve With Breakfast Strata

A breakfast casserole usually is made with eggs, meat, cheese, and bread. So, a side of fruit or vegetables works well. A yogurt parfait or a fruit smoothie can add some balance. Fried apples are also good. 

Here are some other ideas:

  • Serve it for breakfast with a side of bacon or sausages (if you don’t have these two items in your casserole).
  • Serve it for brunch with a green salad or fresh fruit and yogurt. If you want something more substantial, think about a chicken salad. And don’t forget the mimosas!

How to Store Strata Leftovers

Baked Strata: This overnight strata recipe makes a perfect leftover meal, and leftovers will keep in the refrigerator for up to a week. To freeze baked leftover breakfast casserole, wrap it well and place it in the freezer for up to 3 months. Simply thaw and reheat when needed.

Unbaked Strata: You can tightly cover an unbaked casserole and place it in the freezer for up to 3 months. To use, allow it to thaw in the refrigerator overnight. Remove it from the fridge for about 30 minutes before putting it in the oven. Bake at 350°F as directed or until heated through.
