Make It Your Way

One of the best things about this Crescent Roll Breakfast Casserole Recipe is how easy it is to tweak. I often swap out veggies based on what’s fresh, and sometimes I switch up the cheese or sausage to keep things exciting.

Vegetarian Variation: I’ve made it with sautéed mushrooms and spinach instead of sausage—just as satisfying and a great way to get greens in.
Spicy Kick: Throw in some diced jalapeños or use a spicy sausage if you like a little heat in your morning.
Dairy-Free Option: Use dairy-free cheese and milk alternatives to adapt it for lactose intolerance without sacrificing taste.
Seasonal Twists: Pumpkin puree and sage work wonderfully in fall, while tomatoes and basil add a fresh summer vibe.

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

Step 1: Prepping the Sausage and Veggies

First things first, brown your sausage in a skillet until fully cooked and nicely caramelized. While that’s happening, dice your bell peppers and slice the green onions. I find slightly softer peppers work best, so cooking them briefly with the sausage or sautéing separately keeps their flavor mellow and texture tender.

Step 2: Whisking the Egg Mixture

In a large bowl, whisk together eggs, milk, diced peppers, green onions, and seasoned salt until the mixture is smooth and combined. This is what creates that rich, custard-like texture once baked, so take your time making sure it’s well mixed.

Step 3: Layering the Casserole

Spread the cubed croissant rolls evenly in your greased 9x13 baking dish. Then sprinkle the cooked sausage over the top, followed by a generous layer of shredded cheese. Finally, carefully pour the egg mixture over everything, letting it soak into the bread cubes and fill every nook.

Step 4: Baking or Overnight Preparing

You can cover and refrigerate the casserole overnight, which really helps those croissant cubes soak up maximum flavor and moisture. Or, if you’re short on time, bake it immediately in a preheated 375°F oven for about 30 minutes. You’ll know it’s done when the center sets and the edges turn golden and bubbly.

Top Tip

I’ve made this Crescent Roll Breakfast Casserole Recipe dozens of times, and here are a few kitchen tips that will help it turn out perfect every time.

Don’t Skip Refrigerating Overnight: If you have the time, letting it sit overnight makes the casserole moister and helps the flavors marry beautifully.
Use Fresh Sausage: Cooking your sausage fully and draining excess grease before adding prevents a greasy final dish.
Press Gently: After pouring your egg mixture, press the bread cubes lightly to help them soak up the liquid without making the casserole soggy.
Watch Your Bake Time: Ovens vary, so start checking around 25 minutes; overcooking can dry it out.

How to Serve Crescent Roll Breakfast Casserole Recipe

crescent roll breakfast - Serving Suggestion

Garnishes

I love sprinkling freshly chopped parsley or extra green onions on top right before serving—it adds a pop of color and fresh brightness that cuts through the richness. A dollop of sour cream or ketchup on the side is also a popular choice in my house.

Side Dishes

This casserole pairs perfectly with a simple side of fresh fruit or a crisp green salad to balance the richness. Roasted potatoes or even a light yogurt parfait complement it nicely if you want a heartier breakfast spread.

Creative Ways to Present

For holidays or brunch parties, I’ve served individual portions in small ramekins layered with festive veggies and different cheese blends. It’s a fun way to personalize servings and impress your guests with style and flavor.

Make Ahead and Storage

Storing Leftovers

Once cooled, I wrap leftovers tightly in plastic wrap or store them in an airtight container and refrigerate for up to 3 days. This casserole reheats beautifully, making it perfect for quick breakfasts later in the week.

Freezing

Freezing works well too! After baking, let it cool completely, then wrap tightly with foil and freeze. When ready, thaw overnight in the fridge and warm in the oven at 350°F until heated through.

Reheating

To reheat, I like to use the oven or toaster oven rather than the microwave to keep the crust flaky. Cover loosely with foil to prevent over-browning and warm at 350°F for about 15-20 minutes.

Frequently Asked Questions:

Can I use refrigerated crescent roll dough instead of croissant rolls?

You can technically use refrigerated crescent roll dough, but the texture will be less flaky and buttery compared to cubed croissant rolls. For best results, stick with croissant rolls to get that signature richness and layered crispiness.

How long can I refrigerate the casserole before baking?

You can safely refrigerate the casserole overnight for up to 12 hours. This resting time allows the liquid mixture to soak into the croissants, resulting in a moister, more custardy casserole.

Can I make this casserole vegetarian?

Absolutely! Simply omit the sausage and add your favorite sautéed vegetables like mushrooms, spinach, or zucchini. You can also add extra cheese or a vegetarian sausage substitute to keep it hearty.

What cheese works best in this recipe?

I usually use sharp cheddar for its great melting quality and flavor, but you can experiment with Monterey Jack, mozzarella, or even a blend of cheeses for a unique twist. Just make sure to use a good melting cheese for that gooey texture.

Final Thoughts

This Crescent Roll Breakfast Casserole Recipe has become one of those warm, comforting staples that I reach for when I want to treat my family without spending all morning in the kitchen.
