Biscuits and Gravy Breakfast Casserole With Layered Biscuits

• Biscuits are cut and tucked into the filling, which gives them tender centers and browned ridges instead of a separate top that can slide away from each serving.
• Cooking the sausage first leaves a seasoned base for the gravy, while the egg mixture holds the portions together without turning the dish into a dense strata.
• One nine-by-thirteen-inch pan portions into eight substantial squares, useful when breakfast needs to be packed, carried, and eaten with a fork or folded napkin at a desk before meetings begin.

• 1 pound bulk pork breakfast sausage (454 g)
• 1 (16-ounce) tube refrigerated flaky biscuit dough (454 g)
• 6 large eggs (300 g)
• 2 1/2 cups whole milk (600 g)
• 2 (2.75-ounce) packets peppered country gravy mix (156 g)
• 1/2 teaspoon garlic powder (2 g)
• 1/2 teaspoon ground black pepper (1 g)
• 2 cups shredded sharp cheddar cheese (226 g)
• 2 tablespoons chopped scallions, optional (12 g)
• 1 tablespoon unsalted butter, for the baking dish (14 g)

Ingredient notes

• Refrigerated flaky biscuit dough gives the layered look without mixing a separate dough. Cut each biscuit into six pieces so it disperses through the casserole; larger chunks can remain doughy beneath the gravy after baking.
• Use bulk pork breakfast sausage, mild or hot, and break it into small crumbles while browning. Links work after casings are removed, but finely crumbled sausage distributes more evenly through every slice in the pan.
• A packet of peppered country gravy mix keeps the ingredient list short and provides the classic creamy layer. Prepare it with milk rather than water for fuller body, then cool it briefly before combining in this recipe.
• Eggs bind the biscuit pieces and gravy into scoopable squares, rather than a loose sausage-and-sauce bake. Whisk until no streaks remain, especially around the yolks, for an even set throughout.
• Sharp cheddar adds a savory top and a little structure as the casserole rests. Shred from a block when possible; pre-shredded cheese is convenient, though its coating can melt less smoothly on top.

1. 1Heat the oven

   Set a rack in the center and heat the oven to 350°F. Butter a 9-by-13-inch baking dish, including the corners. Keep the biscuit dough chilled while you prepare the filling; cold dough is easier to cut into neat, distinct pieces.

2. 2Brown the sausage

   Cook sausage in a large skillet over medium heat, breaking it into small crumbles, until browned with no pink remaining. Spoon off excess fat if the pan looks greasy. Scatter the sausage across the prepared dish, leaving it in an even layer.

   

3. 3Whisk the custard

   Whisk the eggs, milk, pepper, and garlic powder in a bowl until completely smooth. Prepare the gravy mix in a saucepan according to its package directions using the milk listed here. Let it stand for five minutes, so hot gravy does not begin setting the eggs.

4. 4Layer the pan

   Pour half the egg mixture over the sausage, then add half the biscuit pieces and half the gravy. Repeat the layers, pressing a few biscuit pieces gently into the liquid. Finish with cheddar, keeping some gravy visible for a marbled, rather than solid, cheese cap.

   

5. 5Bake until set

   Bake uncovered until the center reaches 160°F and the top is browned, about 35 to 40 minutes. Rotate the dish once if your oven browns unevenly. The gravy should bubble at the edges, and a knife inserted near the center should not bring up wet egg.

6. 6Rest and portion

   Rest the casserole for 10 minutes before cutting eight squares. This pause lets the gravy settle and gives the biscuits a firmer edge for packing. Serve warm with chopped scallions or hot sauce, and use a wide spatula to lift portions without tearing them.

• Cut biscuit dough with a bench scraper or sharp knife, not by tearing. Uniform pieces hydrate at a similar rate, which helps avoid a finished pan with both dry corners and soft, oversized pockets around the gravy seams.
• Do not pour steaming gravy directly over the eggs. Its brief cooling rest matters; whisking hot gravy into the custard can create little cooked egg strands before the dish reaches the oven or uneven patches.
• If the top browns before the middle is set, lay foil loosely over the dish for the final ten minutes. Check the center rather than relying only on color, since biscuit tops brown faster than the egg layer below as it bakes.

Serve each square with sliced tomatoes, sharp fruit, or a small pile of dressed arugula to cut through the creamy gravy. For a larger brunch spread, add orange segments and strong coffee rather than another rich side. Hot sauce, extra black pepper, and scallions belong on the table, not necessarily in the pan. The casserole is filling enough to stand alone for an early lunch, especially with a crisp apple tucked alongside.
