Ingredients Checklist

To achieve the beautiful layers and robust flavors of this dish, you will need the following ingredients. We highly recommend gathering everything and measuring it out before you begin—a process known as mise en place.

For the Casserole Base:

• Refrigerated Biscuit Dough: 1 can (16.3 oz) of large, flaky refrigerated biscuits (such as Grands!). You can use buttermilk or homestyle.

• Breakfast Sausage: 1 pound (16 oz) of premium ground breakfast sausage. (Pork sausage is traditional, but turkey sausage works well if you want a lighter option. Mild or spicy, depending on your preference).

• Eggs: 6 large eggs, room temperature.

• Milk: 1/2 cup whole milk (for whisking with the eggs).

• Cheese: 1.5 cups freshly shredded sharp cheddar cheese. (Avoid pre-shredded bagged cheese, as it contains anti-caking agents that prevent it from melting smoothly).

For the Homemade Sausage Gravy:

• Reserved Sausage Drippings: Leftover in the pan from browning the meat (approx. 2-3 tablespoons). If using a lean sausage like turkey, you may need to add 2 tablespoons of butter.

• All-Purpose Flour: 1/3 cup all-purpose flour.

• Milk: 2.5 to 3 cups of whole milk (warmed slightly in the microwave for smoother blending).

• Seasonings:

  • 1/2 teaspoon kosher salt (adjust to taste depending on the saltiness of your sausage).

  • 1 full teaspoon freshly ground black pepper (a heavy hand with black pepper is the secret to authentic Southern gravy).

  • 1/2 teaspoon garlic powder (optional, but highly recommended for depth of flavor).

Step-by-Step Instructions

Step 1: Prepare the Oven and Baking Dish

1. Preheat your oven to 350°F (175°C).

2. Generously grease a 9×13-inch glass or ceramic baking dish with non-stick cooking spray or a pat of softened butter. Setting up your baking dish first ensures you have a place to start layering immediately.

Step 2: Prep the Biscuit Base

1. Open the can of refrigerated biscuits. Using a sharp knife or kitchen shears, cut each raw biscuit into quarters (four equal pieces).

2. Scatter the biscuit pieces evenly across the bottom of your prepared 9×13-inch baking dish. Ensure there are no massive gaps, but don’t press them down too hard; you want them to have room to puff up and rise during baking.

Step 3: Cook the Breakfast Sausage

1. Place a large skillet (cast iron or heavy-bottomed stainless steel works best) over medium-high heat.

2. Add the ground breakfast sausage to the skillet. Using a meat chopper or a wooden spoon, break the sausage apart into small crumbles.

3. Cook for 7 to 9 minutes, stirring occasionally, until the sausage is completely browned and cooked through, with no pink remaining.

4. Using a slotted spoon, remove the cooked sausage from the skillet and scatter it evenly over the layer of quartered biscuits in your baking dish. Crucial step: Do NOT discard the grease left in the skillet. This liquid gold is the flavor base for your gravy.

Step 4: Whisk the Eggs and Layer the Cheese

1. In a medium mixing bowl, crack the 6 large eggs. Add the 1/2 cup of whole milk and a small pinch of salt and pepper. Whisk vigorously until the yolks and whites are fully combined and slightly frothy.

2. Sprinkle the 1.5 cups of shredded sharp cheddar cheese evenly over the sausage and biscuits in the baking dish.

3. Slowly pour the whisked egg mixture over the entire casserole, trying to coat as many of the biscuit pieces as possible.

Step 5: Create the Perfect Sausage Gravy

1. Return your skillet with the reserved sausage drippings to medium-low heat. (If you have less than 3 tablespoons of grease, melt a little butter into the pan to make up the difference).

2. Sprinkle the 1/3 cup of all-purpose flour evenly over the hot grease. Whisk continuously for about 1 to 2 minutes. This creates a roux and cooks out the raw flour taste. The mixture will look like a thick, golden paste.

3. Slowly pour in the 2.5 cups of warm milk, about a half-cup at a time, whisking constantly to prevent lumps from forming.

4. Add the heavy dose of black pepper, salt, and garlic powder.

5. Allow the gravy to simmer gently for 4 to 5 minutes, stirring frequently, until it thickens beautifully to the consistency of pancake batter. If it gets too thick, whisk in the remaining 1/2 cup of milk.

Step 6: Final Assembly and Baking

1. Carefully pour the thick, peppery sausage gravy evenly over the top of the unbaked casserole in the 9×13 dish. Use a spatula to spread it gently so it covers the eggs, cheese, and biscuits entirely.

2. Place the casserole dish on the middle rack of your preheated oven.

3. Bake uncovered for 35 to 45 minutes. You are looking for the edges to be bubbling vigorously, the center to be completely set (no jiggling raw egg), and the biscuits underneath to be cooked through and fluffy.

Step 7: The Last of the Recipe (Resting & Serving)

1. The Resting Phase: This is arguably the most important step for the perfect slice. Remove the casserole from the oven and set it on a wire cooling rack. Allow the casserole to rest for 10 to 15 minutes before cutting into it.

2. Why rest? The resting period allows the piping hot gravy to set up and the eggs to finish firming. If you slice it immediately, the casserole will fall apart and become a messy puddle. Resting ensures clean, beautiful, defined squares that show off all the gorgeous layers.

3. Slice into large squares and serve warm. Garnish with a sprinkle of fresh parsley or chives for a pop of color, and offer hot sauce on the side for those who like a morning kick.

Pro-Tips for Success and Make-Ahead Options

• Overnight Prep: You can assemble the bottom layers of this casserole the night before! Layer the biscuits, cooked sausage, and cheese. Whisk the eggs and milk, pour them over top, cover tightly with plastic wrap, and refrigerate overnight. In the morning, make the fresh gravy, pour it over the cold casserole, and bake. (You may need to add 5-10 extra minutes to the baking time since the dish is starting cold).

• Biscuit Tip: Do not use pre-baked biscuits. The magic of this dish relies on the raw biscuit dough soaking up the egg mixture and gravy while baking, resulting in a dumpling-like, tender texture.

• Low-Carb Alternative: While this is a famously high-carb comfort food, if you are strictly following a low-carb diet, you can omit the biscuit dough entirely. Double the eggs to 12, use a keto-friendly flour alternative (like a small amount of xanthan gum or heavy cream reduction) to thicken the gravy, and bake as a crustless sausage and gravy frittata.
