Can I use crescent roll dough instead of biscuits?

Absolutely! Crescent roll dough makes a thinner, flakier base. Press the seams together well and pre-bake for about 5 minutes before adding the other ingredients to prevent sogginess.

My family doesn't eat pork. What can I substitute for the breakfast sausage?

Turkey or chicken breakfast sausage works perfectly! You can also use ground beef seasoned with sage, thyme, and a pinch of maple sugar for a similar flavor profile.

Can I prepare this without milk for a dairy-free version?

Yes! Substitute the milk with unsweetened almond milk or another non-dairy alternative. For the cheese, use your favorite dairy-free shredded cheese substitute.

The casserole is browning too quickly but doesn't seem cooked through. What should I do?

This is common with egg dishes. Simply cover the top loosely with aluminum foil to prevent further browning, and continue baking until the center reaches 160°F or a knife inserted in the center comes out clean.

How to Make Breakfast Casserole with Biscuits

Step 1: Prepare Your Baking Dish

Preheat your oven to 350°F and lightly grease a 9×13 baking dish to prevent sticking. This step is crucial for easy serving later.

Step 2: Create the Biscuit Base

Arrange the jumbo buttermilk biscuits across the bottom of your prepared dish, gently pressing them down to form a complete layer. Don’t worry about gaps – they’ll fill in as they bake.

Step 3: Cook the Sausage

In a large skillet over medium heat, cook the breakfast sausage until browned, breaking it into crumbles as it cooks. Drain off any excess fat – this prevents a greasy casserole.

Step 4: Prepare the Egg Mixture

In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined. The mixture should be smooth and uniform in color.

Step 5: Layer the Casserole

Sprinkle the cooked sausage evenly over the biscuit layer, then pour the egg mixture over everything. Make sure the egg mixture reaches all corners of the dish. Top everything with an even layer of shredded cheddar cheese.

Step 6: Bake to Perfection

Bake in your preheated oven for 35-40 minutes until the eggs are set and the cheese is melted and bubbly. If the top starts browning too quickly, loosely cover with foil and continue baking.

Step 7: Finish and Serve

Remove from the oven and let stand for 5 minutes before garnishing with sliced scallions. The brief rest helps the casserole set up for easier cutting and serving.

Pro Tips for Making the Recipe

Cheese Tip: Reserve about 1/4 cup of cheese to sprinkle on during the last 5 minutes of baking for an extra golden, crispy top.
Biscuit Selection: While any jumbo buttermilk biscuits work, Pillsbury Grands give consistently excellent results.
Test for Doneness: Insert a knife in the center – if it comes out clean without raw egg, your casserole is ready.
Room Temperature Ingredients: Let your eggs and milk sit at room temperature for about 30 minutes before mixing for the smoothest texture.
Even Distribution: Use the back of a spoon to gently press the sausage into an even layer before adding the egg mixture.

How to Serve

Perfect Pairings

Serve with fresh fruit for a balanced meal – berries or citrus provide a refreshing contrast to the rich casserole.

Sauce Options

Offer hot sauce, maple syrup, or country gravy on the side for guests to customize their portions.

Complete Breakfast

For a show-stopping breakfast spread, pair with a simple green salad, yogurt parfaits, and freshly squeezed orange juice.

Make Ahead and Storage

Make Ahead Instructions

Assemble the entire casserole the night before, cover tightly with plastic wrap, and refrigerate. Add an extra 5-10 minutes to the baking time when cooking from cold.

Storing Leftovers

Refrigerate leftovers in an airtight container for up to 3 days. Individual portions make great grab-and-go breakfasts throughout the week.

Freezing

This casserole freezes beautifully! Cut cooled leftovers into portions, wrap individually in plastic wrap, then foil, and freeze for up to 2 months.

Reheating

For refrigerated leftovers, microwave individual portions for 1-2 minutes. For frozen portions, thaw overnight in the refrigerator, then microwave for 2-3 minutes, or reheat in a 325°F oven until warmed through.
