Ingredients Equipment Method Notes

Ingredients

  

For the Base

• 1 lb Breakfast sausage ground
• 1 cup Onion finely chopped
• 1 cup Cheddar cheese shredded, divided
• 2 cups Day-old bread or stale bread cut into 1-inch cubes

For the Egg Mixture

• 10 Large eggs
• 2 cups Milk whole or 2%
• 1/2 tsp Salt
• 1/4 tsp Black pepper freshly ground
• 1/4 tsp Garlic powder
• 1/8 tsp Cayenne pepper (optional, for a kick)

For Garnish (Optional)

• 2 tbsp Fresh parsley chopped

Equipment

• 9x13 inch Baking Dish
• Large Skillet
• Large Mixing Bowl
• Whisk
• Measuring Cups and Spoons

Method

 

Prepare Ingredients

• Preheat oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish.
• In a large skillet over medium heat, cook the ground breakfast sausage and chopped onion, breaking up the sausage with a spoon, until the sausage is browned and the onion is softened, about 8-10 minutes. Drain off any excess grease and set aside.

Assemble the Casserole

• Spread the bread cubes evenly in the bottom of the prepared baking dish.
• Sprinkle half of the shredded cheddar cheese (1/2 cup) over the bread cubes. Then, evenly distribute the cooked sausage and onion mixture over the cheese and bread.
• In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and cayenne pepper (if using) until well combined.
• Carefully pour the egg mixture over the sausage, cheese, and bread in the baking dish, ensuring the bread is well saturated.
• Sprinkle the remaining half of the shredded cheddar cheese (1/2 cup) over the top of the casserole.

Bake and Serve

• Bake for 40-45 minutes, or until the casserole is set in the center and golden brown on top. A knife inserted near the center should come out clean.
• Remove from the oven and let rest for 5-10 minutes before serving. This helps the casserole set and makes for cleaner slices.
• Garnish with fresh chopped parsley, if desired, and serve warm.

Notes

For a make-ahead option, assemble the casserole the night before, cover with plastic wrap, and refrigerate. In the morning, remove from the fridge 30 minutes before baking and bake as directed. You may need to add an extra 5-10 minutes to the baking time if baking directly from cold. Feel free to add diced bell peppers or mushrooms with the onion for more vegetables.

Pro Tips for Making This Sausage Egg Breakfast Casserole

Through years of cooking, I’ve picked up a few tricks that truly elevate a dish like this. For a Sausage Egg Breakfast Casserole that sings, consider these personal tips.

Don’t Overmix the Eggs: When whisking the eggs and milk, mix just until combined. Overmixing can lead to a tougher casserole. I find that a gentle hand keeps the eggs wonderfully light and fluffy.

My Secret Trick: For a truly golden-brown top and slightly crispy edges, I always preheat my oven just a little hotter for the first 10 minutes of baking, then reduce it for the remainder. This gives it a beautiful crust without drying out the interior.

Let It Rest: Just like a good roast, letting your casserole rest for 5-10 minutes after it comes out of the oven allows the eggs to set properly, making for cleaner slices and preventing it from falling apart. Trust me, it’s worth the short wait!

Fun Variations for Sausage Egg Breakfast Casserole

One of the things I adore about casserole recipes is how adaptable they are. This Sausage Egg Breakfast Casserole is no exception! You can easily tweak it to suit your family’s tastes or what you have on hand.

• Spice It Up: If you love a little kick, add a pinch more cayenne pepper, or even some diced jalapeños along with the onion.
• Veggie Boost: Stir in some sautéed bell peppers, spinach, or even diced mushrooms for extra flavor and nutrients. My family sometimes requests a mix of bell peppers, and it adds lovely color and sweetness.
• Cheese Please: While cheddar is classic, try a blend of Monterey Jack, Gruyere, or even a little cream cheese for extra richness in your Sausage Egg Breakfast Casserole.
• Meat Swaps: Not a sausage fan? Use cooked and crumbled bacon, diced ham, or even a plant-based breakfast sausage for a different spin.

What to Serve With Sausage Egg Breakfast Casserole

This Sausage Egg Breakfast Casserole is a meal in itself, but a few simple sides can truly complete the breakfast or brunch experience. I love pairing it with fresh, vibrant flavors.

Consider a simple fruit salad with seasonal berries and melon, or some lightly roasted asparagus for a touch of green. A warm bowl of grits or some crispy hash browns also complement the richness perfectly. My personal tip? A dollop of your favorite salsa or hot sauce on the side adds a fantastic zing that cuts through the richness beautifully.

How to Store Sausage Egg Breakfast Casserole

Leftovers of this delightful Sausage Egg Breakfast Casserole are a gift that keeps on giving! To store, ensure the casserole has cooled completely, then transfer it to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days.

For longer storage, individual portions can be wrapped tightly and frozen for up to 1-2 months. When reheating, I always recommend covering it loosely with foil and warming it gently in the oven at 300°F (150°C) until heated through. This helps maintain that lovely, moist texture. Reheating slowly really does bring the dish back to life!
