How to Make Baked Sausage Squares

1. Preheat the oven: Heat the oven to 350°F. Lightly grease an 8×8-inch baking dish or cast-iron skillet.
2. Cook the sausage: Brown the breakfast sausage in a skillet over medium heat, breaking it into small crumbles as it cooks. Drain any excess grease.
3. Mix the ingredients: Whisk the eggs in a large bowl. Add the shredded cheddar cheese, biscuit baking mix, and cooked sausage. Stir until everything is evenly combined.
4. Fill the baking dish: Pour the mixture into the prepared dish and spread it into an even layer.
5. Bake: Bake for 25 to 30 minutes, or until the center is completely set and the edges are lightly golden.
6. Cool and slice: Allow the sausage bake to rest for 5 to 10 minutes before cutting it into 12 squares. Serve warm.

Easy Variations

Make it spicy: Use hot breakfast sausage for a little extra heat.

Change the cheese: Sharp cheddar adds a bold flavor, while Colby-Jack creates a milder and extra-melty result.

Add vegetables: For more color and flavor, stir in finely chopped bell peppers, onions, or spinach.

Make it ahead: Cook and refrigerate the sausage the night before. In the morning, simply combine the ingredients and bake.

Feed a crowd: Double the ingredients and bake in a greased 9×13-inch dish. Allow a little extra time for the center to cook through.

Helpful Baking Tips

• Drain excess sausage grease so the squares don’t become oily.
• Don’t remove the casserole from the oven until the center is fully set.
• If the top browns too quickly, loosely cover it with foil for the final few minutes.
• Let the baked sausage squares rest before slicing so they hold their shape better.
• For the best texture, shred the cheese yourself if possible.

What to Serve With Sausage Squares

Serve these warm breakfast sausage squares with scrambled eggs, fresh fruit, hash browns, sliced tomatoes, or a simple green salad. For brunch or a party, add hot sauce, salsa, or a small drizzle of honey for a sweet-and-savory combination.

Recipe Benefits

This recipe is especially useful when you need a quick breakfast casserole without a long ingredient list. The combination of eggs and sausage provides protein, while cheddar cheese adds richness and flavor. Because the squares can be prepared ahead of time and cut into individual portions, they are also convenient for breakfast meal prep and feeding a crowd.
