Necessary ingredients

This is just an overview of the ingredients I used and why. For the full recipe, scroll to the end of the post.

Crescent rolls: Your favorite brand of refrigerated crescent rolls makes the perfect crust for this breakfast casserole. They are ready to use and have a slightly sweet flavor and a soft texture, perfect for supporting the casserole filling.
Vegetables: I used a mix of poblanos, jalapeños and white onion to give the casserole a Mexican flavor profile. You can add other favorite vegetables or adjust the spice level by substituting bell peppers or serrano peppers to suit your preference.
Breakfast sausage: A must for this casserole. I kept things gentle by using regular or mild-flavored breakfast sausages, but you can also use hot or even sage. Pork, beef, or your favorite crumbled sausage works for your favorite plant-based breakfast.
Egg: You will need 6 large eggs.
Milk: It adds a little creaminess to the egg mixture. I used low-fat milk, but you can also use whole milk to obtain a creamier consistency.
Taco seasoning: This seasoning blend keeps things convenient and simple. You can use your favorite store-bought confection or my homemade taco seasoning recipe.
Grated cheese: This is layered throughout the casserole to give cheese in every bite. I used shredded Mexican cheese, but you can use Monterey Jack, cheddar, mozzarella, or whatever combination you have.
Seasonings: I like to garnish mine with cilantro, red onion, and a drizzle of sour cream.

How to Make a Crescent Roll Breakfast Casserole

Crescent dough pressed into foil in bottom of large baking dish.

Cook the poblano, jalapeño and onion in a skillet for 5 to 7 minutes until soft and tender, then add the breakfast sausage and cook for another 10 minutes until fully cooked.
Unroll the crescent rolls and press them into the bottom of a large 9×13-inch baking dish. Pinch the seams together to seal and create a layer of dough. Precook it for 5 minutes at 375ºF.
Whisk together the eggs, milk, shredded cheese and taco seasoning. Add the sausage mixture on top of the pre-cooked dough, then top with the beaten egg mixture and top with more cheese.
Bake for 20-25 minutes, until the center of the casserole is set and golden.

Tips and variations for the recipe

Keep eggs soft. Be sure to beat the egg mixture until light and fluffy for fluffy eggs.
Go ahead. You can easily prepare this casserole in advance. Simply assemble the casserole the night before, cover it with plastic wrap and place it in the fridge overnight, then cook as directed when you’re ready to serve.
Swap proteins. You can use chopped ham or crispy bacon in place of breakfast sausage or spicy sausage for an even spicier twist.
Add the vegetables. You can use almost any veggies you have on hand, such as mushrooms, peppers, black olives or spinach.

Frequently asked questions

Can I make a breakfast casserole with the crescent roll the night before and bake it in the morning?

Absolutely! Simply assemble the casserole as directed, then cover with plastic wrap or aluminum foil and refrigerate overnight. Cook as directed in the morning for a quick and delicious breakfast.

How do I keep crescent rolls from getting soggy in the casserole dish?

Pre-baking the crescent dough crust is key to preventing sogginess. The crescent roll dough absorbs some of the egg mixture, so it’s important to pre-bake for about 5 minutes to help the crust hold its shape and support the filling.

Can I replace the crescent rolls with other types of dough or bread?

Yes, you can use crusty bread or frozen hash browns instead of crescent rolls. If using crusty bread, be sure to dice them and spread them in an even layer. Sourdough is a great option; the crunchier and stalier it is, the more it will resist the filling.

Storage and heating

To conserve, Transfer crescent-shaped casserole to an airtight container and refrigerate for up to 1 week. You can also freeze it in a freezer-safe container or bag for up to 3 months.
