Ingredient Quantity Purpose

Step-by-Step Preparation Guide

Follow these precise instructions for a flawless sausage biscuit casserole every time. The method matters as much as the ingredients for achieving the perfect balance between crispy top and tender interior.

  1. Brown the sausage in a large skillet over medium heat, breaking into small crumbles until no pink remains (about 8-10 minutes). Drain excess fat but retain 1 tablespoon for flavor.
  2. Prepare biscuit base by tearing biscuits into 1-inch pieces and arranging half in a greased 9x13-inch baking dish.
  3. Add first cheese layer by sprinkling 1 cup shredded cheddar evenly over the biscuit pieces.
  4. Spread sausage evenly over the cheese layer, ensuring coverage to the edges.
  5. Add remaining biscuits as the top layer, pressing down gently to create contact with sausage.
  6. Whisk wet ingredients thoroughly: eggs, milk, Dijon mustard, salt, and black pepper until completely combined.
  7. Pour egg mixture slowly over the entire casserole, ensuring it seeps between all layers.
  8. Refrigerate (optional) for at least 30 minutes or up to overnight for make-ahead convenience.
  9. Bake uncovered at 350°F (175°C) for 28-32 minutes until center is set and top is golden brown.
  10. Rest before serving for 5-7 minutes to allow structure to set properly.

Professional Tips for Best Results

These expert techniques transform a good sausage biscuit breakfast casserole into an exceptional one. These insights come from testing dozens of variations to identify what truly makes the difference:

  • Don't skip the resting period after baking—this allows the egg mixture to fully set, preventing a runny casserole.
  • Use freshly shredded cheese rather than pre-shredded varieties, which contain anti-caking agents that affect melting quality.
  • For extra crispy top, broil for the final 2-3 minutes of baking, watching carefully to prevent burning.
  • If making ahead, add 5-7 minutes to baking time if going directly from refrigerator to oven.
  • Double the recipe without adjusting baking time when using two 8x8-inch dishes instead of one 9x13-inch dish.

Delicious Variations to Try

While the classic sausage biscuit casserole recipe shines on its own, these tested variations accommodate different tastes and dietary needs without compromising the dish's integrity:

  • Southern-style: Add ½ cup chopped green onions and ¼ cup chopped jalapeños to the sausage for authentic Southern flavor.
  • Vegetarian option: Substitute plant-based sausage and increase mushrooms by 1 cup for similar texture and umami.
  • Lighter version: Use turkey sausage and reduce cheese to 1½ cups while adding ½ cup diced bell peppers for freshness.
  • Holiday special: Layer ½ cup dried cranberries and pecans between the sausage and top biscuit layer for festive occasions.
  • Spicy kick: Mix 1 teaspoon cayenne pepper into the egg mixture and use hot sausage for those who enjoy heat.

Serving and Presentation Ideas

Elevate your sausage biscuit breakfast casserole from simple comfort food to brunch centerpiece with these presentation tips:

  • Cut into uniform squares using a hot knife for clean edges
  • Garnish with fresh chives or parsley just before serving
  • Pair with a simple fruit salad to balance the richness
  • Serve with small pitchers of maple syrup for those who enjoy sweet and savory combinations
  • For holiday brunches, present on a large platter surrounded by fresh berries

Storage and Reheating Guidelines

Proper storage ensures your sausage biscuit casserole maintains quality when making ahead or dealing with leftovers:

  • Refrigeration: Store covered in refrigerator for up to 4 days
  • Freezing: Wrap tightly and freeze for up to 3 months; thaw overnight before reheating
  • Reheating: Cover with foil and warm at 325°F (165°C) for 15-20 minutes until heated through
  • Individual portions: Microwave single servings for 60-90 seconds, adding 10 seconds per additional portion
  • Reviving texture: Sprinkle with 1 tablespoon milk before reheating to restore moisture

Frequently Asked Questions

Can I use frozen biscuits instead of refrigerated for sausage biscuit casserole?

No, frozen biscuits create excess moisture when thawing during baking, resulting in a soggy casserole. Refrigerated biscuits have the proper moisture content and leavening for this recipe. If you only have frozen biscuits, thaw them completely and pat dry with paper towels before using.

How do I prevent my sausage biscuit casserole from becoming too dry?

The key to preventing dryness is proper egg-to-milk ratio and not overbaking. Use whole milk (not lower fat alternatives) and check for doneness at 28 minutes. The center should jiggle slightly when shaken but not be liquid. Letting the casserole rest for 5-7 minutes after baking allows residual heat to finish cooking without drying out.

Can I make sausage biscuit casserole ahead of time for holiday brunch?

Yes, this is an excellent make-ahead breakfast casserole. Assemble completely, cover tightly, and refrigerate for up to 24 hours before baking. Add 5-7 minutes to the baking time if going directly from refrigerator to oven. For best results, don't add the egg mixture more than 12 hours ahead as it can make the biscuits too soggy.

What's the best way to reheat sausage biscuit casserole without drying it out?

Cover the casserole with foil and reheat at 325°F (165°C) for 15-20 minutes. For individual portions, microwave covered with a damp paper towel for 60-90 seconds. Sprinkling with 1 tablespoon of milk before reheating helps restore moisture. Avoid reheating at high temperatures which accelerate moisture loss.

Can I substitute biscuit mix for the refrigerated biscuits in this recipe?

Yes, but with adjustments. Prepare biscuit mix according to package directions, then cut into 1-inch pieces before layering. The texture will be slightly different—more homemade and less uniform—but still delicious. Use the same quantity (about 2 cups of prepared biscuit dough) as you would get from one standard can of refrigerated biscuits.
