Easy Strata Recipe with Sausage and Cheese

This easy strata recipe layers crusty baguette, savory breakfast sausage, onion, garlic, eggs, cream and plenty of cheese into a rich breakfast casserole with a soft, custardy center and golden top.

The best part is that you can assemble it ahead. Let the bread soak for at least an hour—or refrigerate it overnight—then bake it the next morning for an easy breakfast or brunch that feeds a crowd.

A Little Story About This Breakfast Strata

I love a breakfast recipe that actually makes the morning easier. Strata is one of those dishes.

Most of the work happens before anyone is hungry: cook the sausage and vegetables, layer everything with bread and cheese, pour over the egg mixture and put the entire baking dish in the refrigerator.

The next morning, there isn’t a stack of pancakes to flip or individual eggs to cook. I just put one casserole in the oven.

And somehow, that little bit of planning makes breakfast feel much more relaxed—which is exactly what I want when I’m feeding family or having people over for brunch.

Why I Love This Strata Recipe

• Make-ahead friendly: Assemble it at least an hour ahead or refrigerate overnight.
• Great for a crowd: One baking dish makes about 8-10 generous servings.
• Rich and satisfying: Sausage, eggs, cream, bread and cheese make it a complete breakfast.
• Flexible: Add bell pepper, spinach, mushrooms or whatever vegetables you have.
• Simple ingredients: Nothing complicated, but plenty of savory flavor.
• Perfect for holidays: I especially love it for Christmas morning, Easter brunch or weekends with guests.

Ingredients You’ll Need

2 tablespoons olive oil

I use olive oil to brown the sausage and cook the vegetables.

Depending on how much fat your sausage releases, you may not need all of it for the vegetables.

16 ounces breakfast sausage

Use your favorite breakfast sausage. Pork, chicken or turkey sausage all work. Mild sausage keeps the casserole classic, while spicy sausage adds a little heat.

Cook it until nicely browned because that browning builds flavor before everything goes into the baking dish.

1 yellow onion, diced

Onion adds sweetness and savory depth. I give it about 8 minutes in the skillet so it becomes properly soft rather than remaining crunchy inside the finished strata.

3 garlic cloves, minced

Add the garlic after the onion and optional pepper have softened. Keep the heat moderate and cook just until fragrant so the garlic doesn’t burn.

1 bell pepper, diced, optional

Red, yellow or orange bell pepper adds sweetness and color. I cook it before assembling the strata so it loses some moisture and becomes tender.

8 large eggs

Eggs form the custard that binds the bread, sausage and vegetables together. Whisk them thoroughly before adding the cream and seasonings.

1½ cups heavy cream

Heavy cream makes the breakfast strata rich and custardy. For a slightly lighter version, use 1 cup heavy cream plus ½ cup milk.

1 teaspoon ground mustard

Ground mustard is one of those small ingredients that makes a breakfast casserole taste more savory without making it taste obviously mustardy.

If you don’t have ground mustard, Dijon mustard is an easy substitute.

½ teaspoon garlic powder

Even with fresh garlic in the filling, garlic powder seasons the custard itself so the flavor is distributed throughout the casserole.

½ teaspoon onion powder

Onion powder does the same thing, giving the egg mixture a little extra savory depth.

1 baguette, cut into chunks

A crusty baguette is ideal because it can absorb plenty of egg mixture without completely falling apart.

Slightly stale bread is even better. Cut it into generous bite-sized chunks rather than tiny cubes so you still get distinct pieces of bread after baking.

1 cup shredded cheese

Cheddar is an easy choice, but Gruyère, Swiss, Monterey Jack or a combination all work. For a richer brunch strata, I especially like Gruyère with sausage and onion.

Salt and black pepper, to taste

Season both the sausage mixture and egg custard thoughtfully.

Breakfast sausage and cheese can already contain plenty of salt, so taste the cooked filling before adding too much.

Substitutions and Variations

Spinach Strata

Add 2 cups fresh spinach to the skillet after cooking the onion and pepper. Cook just until wilted before assembling.

If using frozen spinach, thaw it and squeeze out as much liquid as possible first.

Sausage and Mushroom Strata

Add about 2 cups sliced mushrooms. Cook them until their moisture has evaporated before putting them into the casserole so they don’t make the bread soggy.

Ham and Cheese Strata

Replace the sausage with about 2 cups diced cooked ham. Because the ham is already cooked, you can add it directly to the casserole.

Bacon Strata

Replace the breakfast sausage with cooked, crumbled bacon.

Vegetarian Breakfast Strata

Leave out the sausage and add a combination of spinach, mushrooms, peppers, broccoli or asparagus.

Change the Cheese

Try:

• sharp cheddar
• Gruyère
• Swiss
• Monterey Jack
• mozzarella
• pepper Jack
• crumbled feta

Use a Different Bread

Instead of baguette, use sourdough, Italian bread, challah or another sturdy crusty loaf.

Avoid very soft sandwich bread unless it is quite stale because it can become overly soft once soaked.

Add Fresh Herbs

Fresh chives, parsley or thyme are all easy additions.

How to Make Breakfast Strata

1. Brown the Sausage

Heat the olive oil in a large skillet over medium heat. Add the breakfast sausage and cook, breaking it into small pieces, until browned and cooked through.

Transfer the sausage to a plate or bowl.

2. Cook the Onion

Add the diced onion to the same skillet. Cook over medium heat for about 8 minutes, stirring occasionally, until softened.

Those browned bits left from the sausage are flavor, so I like cooking the vegetables in the same pan.

3. Add the Bell Pepper

If using bell pepper, add it to the onion and cook for another 3 minutes until it begins to soften.

4. Add the Garlic

Add the minced garlic. Cook for another 1–3 minutes over moderate heat, just until fragrant, being careful not to let it burn.

Remove the skillet from the heat.

5. Make the Egg Mixture

In a large bowl, whisk together the eggs, heavy cream, ground mustard, garlic powder, onion powder, salt and pepper.

Whisk until the eggs are completely broken up and the cream is evenly incorporated.

6. Start Layering the Strata

Lightly grease a 9×13-inch baking dish. Arrange half of the baguette pieces across the bottom. Top with half of the sausage and onion mixture. Pour over half of the egg mixture. Sprinkle with half of the shredded cheese.

7. Repeat the Layers

Add the remaining bread, followed by the remaining sausage mixture. Pour over the rest of the egg mixture and finish with the remaining cheese.

Gently press the bread down with the back of a spoon or spatula so more of it comes into contact with the custard.

8. Refrigerate

Cover the baking dish and refrigerate for at least 1 hour. For the best make-ahead option, refrigerate overnight.

This resting time gives the baguette a chance to absorb the egg and cream mixture.

9. Bake Covered

Preheat the oven to 375°F. Bake the strata covered for 30 minutes. Covering it initially helps the center cook without the bread and cheese becoming too dark.

10. Finish Uncovered

Remove the cover and continue baking for another 10–15 minutes. The strata is ready when the top is golden and bubbling and the egg mixture in the center is fully set.

Let it rest for about 10 minutes before slicing.

How to Store Leftover Strata

Let leftover strata cool, then cover it tightly or transfer slices to an airtight container.

Store in the refrigerator for up to 3–4 days.

Reheat individual portions in the microwave for convenience, or warm them in a 350°F oven if you want the bread and cheese on top to crisp up again.

How to Make Strata Ahead

This is one of the main reasons I love breakfast strata.

Assemble the entire casserole the night before, cover tightly and refrigerate. The bread will slowly soak up the egg mixture while you sleep.

The next morning, bake according to the recipe.

If your baking dish is very cold, I like letting it sit out briefly while the oven preheats—provided your specific baking dish is safe to move from refrigerator temperatures toward a hot oven.

You can also prepare the sausage and vegetable mixture a day ahead and refrigerate it separately, then assemble the casserole later.

Frequently Asked Questions

What is a strata?

A strata is a savory layered casserole usually made with bread, eggs, dairy, cheese and optional vegetables or meat.

The name fits the dish perfectly because everything is arranged in layers before baking. Think of it as somewhere between a breakfast casserole and savory bread pudding.

What is the difference between strata and breakfast casserole?

Breakfast casserole is a broad category. A strata is a specific type of breakfast casserole that uses bread soaked in an egg-and-dairy mixture.

What is the difference between strata and frittata?

A frittata is primarily eggs with vegetables, cheese or meat.

Strata contains bread, which absorbs the egg custard and gives the finished dish a softer, bread-pudding-like texture.

Does strata have to sit overnight?

No. This egg strata recipe needs at least about one hour of soaking time, but overnight is convenient and allows the bread plenty of time to absorb the custard.

Why does strata need to soak?

The resting time allows the bread to absorb the eggs and cream. Without enough soaking, you can end up with dry pieces of bread sitting above a separate layer of egg.

What bread is best for strata?

Crusty, sturdy bread works best. I like baguette, sourdough, Italian bread or challah.

Slightly stale bread is particularly good because it absorbs the custard without becoming mushy as quickly.

Can I use milk instead of heavy cream?

For a lighter version of this particular recipe, I recommend using 1 cup heavy cream plus ½ cup milk. Using only milk will make the custard less rich.

What other vegetables can I put in breakfast strata?

Bell pepper, mushrooms, spinach, asparagus, broccoli and sautéed zucchini all work. Cook vegetables that release a lot of water before adding them to the baking dish.

Can I make strata without sausage?

Yes. Leave it out for a vegetarian strata or replace it with ham, bacon or another cooked breakfast meat.

Why is my strata soggy?

Common causes include vegetables releasing too much water, very soft bread, or an underbaked center. Sauté watery vegetables first and bake until the middle is completely set.

Why is my strata dry?

Too little custard, bread that was exceptionally dry or overbaking can all make strata dry.

The center should be set, but you don’t want to keep baking long after that point.

How do I know when strata is done?

The center should be set rather than liquid, and the top should be puffed, bubbling and golden. After baking, let it rest for about 10 minutes before slicing.

Can I freeze breakfast strata?

You can freeze cooked portions. Cool completely, wrap individual slices well and freeze in an airtight container.

Thaw overnight in the refrigerator before reheating.

Final Thoughts

A good strata recipe is one of my favorite solutions for feeding people without spending the entire morning in the kitchen.

You get crusty bread, savory sausage, soft onions, creamy eggs and melted cheese in every slice, but almost all the work can happen the night before.

For me, the secret is giving the bread time to soak. Assemble it, put the baking dish in the refrigerator and let time do some of the work for you.

The next morning, all that’s left is baking it until the center is custardy and set and the top is golden—which is exactly the kind of easy, comforting breakfast I want when people are gathered around the table.
