Step‑by‑Step Instructions for Biscuits and Gravy Breakfast Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare a 9x13-inch baking dish by spraying it generously with nonstick spray to ensure easy removal of the casserole later.
Step 2: Cook Sausage
In a large skillet over medium heat, crumble and brown the ground breakfast sausage. Allow it to cook for about 5–7 minutes until fully browned and no pink remains, stirring occasionally to ensure even cooking. The savory aroma will start to fill your kitchen.
Step 3: Make Gravy
Sprinkle the all-purpose flour over the cooked sausage and stir well for about a minute to incorporate. Gradually whisk in the whole milk, allowing the mixture to simmer on low heat. Keep stirring until the gravy thickens, about 3–5 minutes, seasoning with salt and pepper to taste for that perfect savory balance.
Step 4: Prepare Biscuits
While the gravy simmers, take the refrigerated buttermilk biscuits and cut them into quarters. Arrange the biscuit pieces evenly across the prepared baking dish, creating a cozy base for your Biscuits and Gravy Breakfast Casserole.
Step 5: Assemble Casserole
Pour the thickened sausage gravy evenly over the biscuit pieces, ensuring each one gets a generous share. In a separate bowl, whisk together the large eggs and a splash of milk, seasoning the mixture with salt and pepper. Pour this egg mixture over the top, allowing it to seep into the gaps.
Step 6: Bake
Slide the assembled casserole into the preheated oven. Bake uncovered for about 35–40 minutes until the egg is set and the top is beautifully golden and bubbly. Keep an eye on it during the last few minutes for that perfect visual cue of doneness.
Step 7: Cool and Serve
Once out of the oven, let the Biscuits and Gravy Breakfast Casserole cool for 5–10 minutes. This resting period allows the flavors to meld beautifully. Slice into squares and serve warm, sharing this delicious comfort food with your loved ones.
