Step‑by‑Step Instructions for Ultimate Biscuits and Gravy Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, get a 9×13-inch baking dish and coat it generously with nonstick spray to prevent your delicious casserole from sticking later on. This simple step sets the stage for your ultimate Biscuits and Gravy Breakfast Casserole.
Step 2: Cook the Sausage
Heat a large skillet over medium heat and add your ground breakfast sausage. Cook the sausage, breaking it up with a spatula, until it is nicely browned and fully cooked, which should take about 5-7 minutes. Avoid draining the fat, as it will enhance the flavor of your gravy.
Step 3: Make the Gravy
Once the sausage is cooked, sprinkle about 1/4 cup of all-purpose flour over it, stirring well to combine. Gradually whisk in 2 cups of whole milk, ensuring there are no lumps. Cook this mixture, stirring constantly, until it thickens to a creamy consistency, about 5 minutes. Season with salt and black pepper to taste for your Biscuits and Gravy Breakfast Casserole.
Step 4: Prepare the Biscuits
While the gravy is thickening, take your refrigerated buttermilk biscuits and cut them into quarters. Arrange the biscuit pieces evenly in the prepared baking dish, making sure they cover the bottom for a sturdy base. This will soak up all the lovely gravy you’ll be pouring over them shortly.
Step 5: Assemble the Casserole
Pour the sausage gravy mixture evenly over the biscuit pieces, making sure each piece is covered. In a separate bowl, whisk together 6 large eggs, 1/4 cup of milk, salt, and pepper, until smooth. If you are using shredded cheddar cheese, add it here and mix well before pouring it over the sausage gravy and biscuits.
Step 6: Bake the Casserole
Place the assembled Biscuits and Gravy Breakfast Casserole in the preheated oven and bake uncovered for 35-40 minutes. You’ll know it’s ready when the eggs are set and the top is golden and slightly puffed. Keep an eye on it to avoid overbaking.
Step 7: Cool & Serve
After baking, remove the casserole from the oven and allow it to rest for about 5-10 minutes. This resting time helps it firm up a bit for easier slicing. Once ready, cut into squares and serve warm, enjoying the comforting flavors of your hearty Southern breakfast creation!

What if my gravy is too thin?
If you find your gravy is not thickening as expected, don’t fret!

Continue cooking, stirring constantly until thickened. This step will help you achieve that creamy texture we all love in a Biscuits and Gravy Breakfast Casserole.

Also, be sure to avoid adding any allergens like certain cheeses if someone is lactose intolerant.
