Cheesy Breakfast Biscuit Casserole with Savory Sausage Tips, FAQ & printable recipe

Tips for success

For the absolute best results, allow the baked casserole to rest for about 5 to 10 minutes after removing it from the oven. This crucial resting period lets the eggs firm up slightly and allows the steam to escape, making the casserole much easier to slice into clean, neat portions.

If sliced too quickly, the hot cheese and eggs may slide apart, ruining the beautiful layered presentation and the spectacular cheese pull of the finished dish.

If you prefer a more pronounced texture, try browning the biscuit pieces slightly in the baking dish for about five minutes before adding the toppings and egg mixture. This quick par-baking step creates an extra-crispy bottom crust that stands up beautifully to the moist egg custard.

Additionally, ensure your eggs are thoroughly whisked to incorporate plenty of air, which contributes to a significantly lighter, fluffier texture in the finished bake.

Variations

• Spicy Chorizo and Pepper Jack: Swap the mild pork sausage for fresh spicy chorizo and use shredded pepper jack cheese instead of cheddar for a lively Southwestern kick.
• Bacon and Swiss: Replace the sausage with crispy crumbled bacon and swap the cheddar for Swiss cheese to create a classic, smoky breakfast flavor profile.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days.

Freezer

Freeze wrapped individual slices in a freezer-safe bag for up to 2 months.

Reheat

Reheat slices in the oven at 350°F (175°C) for 10-15 minutes or in the microwave for 1-2 minutes.

Store any leftover breakfast casserole in an airtight container in the refrigerator within two hours of cooking. Kept properly covered, the leftovers will remain fresh and delicious for up to three to four days. For longer storage, wrap individual slices tightly in plastic wrap and aluminum foil, then place them in a heavy-duty freezer bag. Frozen slices will maintain good quality for up to two months.

This casserole is an excellent candidate for make-ahead preparation. Assemble the entire dish, minus the egg mixture, the night before, cover it tightly with plastic wrap, and store it in the refrigerator. In the morning, whisk the eggs, pour them over the casserole, and bake as directed, adding about five minutes to the total baking time to account for the chilled ingredients.

Serving ideas

Serve this hearty breakfast casserole warm, straight from the baking dish, using a metal spatula to lift out generous square portions. The dramatic cheese pull and rising steam make for an impressive presentation at any breakfast table.

It is a complete, satisfying meal on its own, but it also pairs beautifully with fresh seasonal fruit, a simple green salad, or a side of crispy hash browns for a larger brunch spread that will satisfy everyone.

To elevate the flavor profile, offer a variety of condiments at the table for guests to customize their slices. Freshly chopped chives or sliced green onions add a bright, fresh contrast to the rich cheese and savory sausage.

A bottle of your favorite hot sauce or a jar of warm salsa provides a welcome kick of acidity and heat that cuts through the richness of the baked eggs and buttery biscuits perfectly.

Cheesy Breakfast Biscuit Casserole with Savory Sausage

Prep 15 minCook 45 minRest 10 minTotal 1 h 10 minServes 8

Ingredients

• 1 lb ground pork sausage
• 1 can (16 oz) refrigerated biscuit dough
• 2 cups shredded cheddar cheese
• 8 large eggs

Instructions

1. Brown the ground pork sausage in a large skillet over medium-high heat, breaking it into small crumbles with a spatula as it cooks. Cook until the sausage is fully browned with no pink remaining, ensuring it reaches an internal temperature of 160°F (71°C). Drain the excess grease thoroughly and set the cooked sausage aside.
2. Open the can of refrigerated biscuit dough and separate the individual biscuits. Use a sharp knife to cut each biscuit into small, uniform quarters on a clean cutting board. Arrange the biscuit pieces in an even layer across the bottom of a greased 9x13-inch glass baking dish.
3. Scatter the cooked and drained sausage evenly over the layer of biscuit pieces in the baking dish. Sprinkle the shredded cheddar cheese uniformly over the sausage and biscuits, ensuring complete coverage.
4. Crack the eggs into a large mixing bowl. Whisk the eggs vigorously until they are fully combined and slightly frothy. Pour the whisked eggs evenly over the biscuit, sausage, and cheese layers in the baking dish, ensuring they seep into all the crevices.
5. Place the baking dish in a preheated oven at 350°F (175°C). Bake for 35 to 40 minutes, or until the casserole is puffed, the top is a deep golden brown, and the eggs are completely set in the center. Verify the egg mixture reaches an internal temperature of 160°F (71°C) before removing from the oven. Let rest for 10 minutes before slicing.
