Green onions:Provide a mild oniony brightness without overpowering the dish.
Seasoned salt:Enhances all the other flavors — a little goes a long way.
Cubed croissant rolls:Butter-rich and soft, they absorb the egg mixture perfectly, creating a tender base.

Make It Your Way

I love putting my spin on this casserole depending on what I have in the fridge. Sometimes, I add sautéed mushrooms or swap the sausage for bacon. Feel free to customize it — that’s part of the fun!

Vegetarian Variation: Replace sausage with sautéed mushrooms and spinach for a meatless but still hearty version. I tried this once for a brunch with veggie-loving friends, and it was a hit.
Spicy Kick: Toss in some diced jalapeños or sprinkle cayenne into the egg mix for a lively heat.
Cheese Swap: Use pepper jack or mozzarella instead of cheddar for a different cheesy vibe.
Make it Gluten-Free: Swap boule bread cubes for gluten-free croissants or rolls — just keep an eye on the cooking time.

Step-by-Step: How I Make Crescent Roll Breakfast Casserole with Sausage Recipe

Step 1: Prep and Cook the Sausage

I start by browning the breakfast sausage in a skillet, breaking it up into small chunks as it cooks. This way, you get those flavorful little pockets of meat dispersed evenly throughout the casserole. Drain any excess grease for a lighter dish.

Step 2: Whisk Together the Egg Mixture

In a large bowl, whisk the eggs, milk, diced bell peppers, green onions, and seasoned salt. The colorful peppers and onion add freshness and a little crunch, which I always appreciate to balance the richness.

Step 3: Layer It Up

Spread cubed croissant rolls evenly in a greased 9x13 baking dish — I make sure the cubes aren’t packed too tight so the egg seeps all through. Then sprinkle cooked sausage bits over the bread, followed by a generous layer of shredded cheese.

Step 4: Pour and Refrigerate or Bake

Pour the egg mixture evenly over the layers. At this point, you can cover the dish and refrigerate overnight to let the flavors meld beautifully, or bake it right away for about 30 minutes at 375°F until the center is set and the top lightly golden.

Top Tip

From my many attempts in the kitchen, a few little tricks make all the difference with this casserole. You want those crescent rolls to soak up enough of the egg mixture without getting soggy and to bake fully through without drying out.

Cube Size Matters: Cut the croissant rolls into bite-sized cubes. If they're too big, the inside won’t cook well; if too small, they may dry out.
Even Layering: Spread sausage and cheese evenly so every slice gets a balanced mix.
Rest Before Baking: If you refrigerate overnight, take the dish out 20 minutes before baking so it heats evenly.
Watch Your Bake Time: Check at 25 minutes—overbaking can make the casserole dry, underbaking leaves eggs runny. Aim for just set in the center.

How to Serve Crescent Roll Breakfast Casserole with Sausage Recipe

crescent roll casserole - Serving Suggestion

Garnishes

I like to top my casserole with a sprinkle of fresh chopped parsley or chives — it adds color and a fresh bite. Sometimes, I add a dollop of sour cream or drizzle hot sauce for an extra kick.

Side Dishes

A side of fresh fruit (think berries or melon) complements the richness perfectly. For a truly cozy brunch, I pair it with crispy hash browns or a light mixed green salad.

Creative Ways to Present

For special occasions, I bake this in individual ramekins or muffin tins—it’s adorable and perfect for portion control. I once used colorful mini bell peppers as “bowls” for individual servings, which wowed my brunch guests.

Make Ahead and Storage

Storing Leftovers

Leftover casserole stores well covered in the fridge for up to 3 days. I recommend wrapping tightly with foil or an airtight lid to keep it from drying out.

Freezing

I’ve frozen this casserole successfully! Just assemble but don’t bake, then wrap tightly with foil and freeze for up to a month. When you’re ready, thaw overnight and bake as usual.

Reheating

To reheat, I prefer the oven—cover with foil and warm at 350°F until heated through, about 15–20 minutes. The foil keeps the edges from getting too crispy while the interior warms up nicely.

Frequently Asked Questions:

Can I use regular crescent rolls instead of croissant rolls?

Yes! You can substitute regular crescent rolls, but the texture might be slightly less flaky. Just make sure to cut them into cubes and bake until the casserole is set.

Can I prepare this casserole the morning of serving?

Absolutely! If short on time, you can assemble the casserole and bake immediately, which takes about 30 minutes. The flavor is slightly better if it rests overnight, but it’s still delicious fresh.

What type of cheese works best in this recipe?

Cheddar is the go-to for its sharp flavor, but you can mix mozzarella, Monterey Jack, or even pepper jack for a different zing. Just use about 1.5 cups shredded cheese total.

Can I make this casserole gluten-free?

Yes, swap out the croissant rolls with gluten-free bread cubes or gluten-free crescent rolls if you can find them. Keep an eye on baking time to ensure it cooks through.
