Assemble A Breakfast Casserole Like This

Step 1: Brown the Sausage

Fire up your oven to 350°F.

Grab a large skillet and heat it over medium-high flame.

Toss in the sausage and cook it until it turns a beautiful golden brown, breaking it into small pieces as you go.

This should take around 7 minutes.

Once done, transfer the sausage to a paper towel-lined plate to drain excess grease.

Step 2: Soften the Bell Pepper

In the same skillet with those delicious sausage drippings, add your chopped bell pepper.

Sauté over medium heat, stirring occasionally until the peppers become tender and slightly softened, about 3-4 minutes.

Scoop them out and join them with the sausage on the plate.

Step 3: Whip Up the Egg Mixture

Grab a large mixing bowl and crack your eggs into it.

Pour in the half-and-half, then sprinkle in:
  • Onion powder
  • Garlic salt
  • Black pepper

Whisk everything together until it’s smooth and well combined.

Fold in:
  • Cooked sausage
  • Sautéed bell peppers
  • Cheddar cheese
  • Pepper Jack cheese

Step 4: Prepare the Hash Brown Base

In a separate bowl, toss the frozen hash browns with:
  • Remaining garlic salt
  • Remaining black pepper

Spread these seasoned hash browns evenly across a greased 13×9-inch baking dish.

Step 5: Combine and Bake

Pour the egg mixture over the hash browns, gently pressing down to ensure everything is nicely nestled.

Slide the dish into the preheated oven and bake for about 45 minutes.

You’ll know it’s ready when the center is set and the hash browns have turned a gorgeous golden brown.

Step 6: Rest and Serve

Let the casserole rest for 15-20 minutes after removing from the oven.

This helps it set and makes cutting easier.

Sprinkle some fresh sliced scallions on top for a pop of color and extra flavor.

Serve hot and enjoy your delicious breakfast feast!

Casserole Tips For Better Breakfast Layers

  • Drain sausage thoroughly on paper towels to prevent soggy hash browns and maintain crispy texture.
  • Grate cheese freshly for better melting and richer flavor compared to pre-shredded varieties.
  • Assemble casserole night before, refrigerate, and bake morning of serving to save precious morning time.
  • Swap sausage with bacon or ham, or use vegetarian protein alternatives for dietary preferences.
  • Let casserole rest after baking to help eggs set completely and make cutting and serving easier.

Breakfast Bake Stays Rich for Another Morning

  • Store leftovers in an airtight container within 2 hours of cooking. Keep refrigerated for up to 3-4 days to maintain freshness and prevent bacterial growth.
  • Wrap individual portions tightly in plastic wrap, then place in freezer-safe containers. Freeze breakfast casserole for maximum 2 months. Label with date for easy tracking.
  • Preheat oven to 350°F. Cover casserole with aluminum foil to prevent drying. Warm for 15-20 minutes until internal temperature reaches 165°F, ensuring even heating.
  • Cut desired portion and microwave on medium power for 1-2 minutes, stopping halfway to stir. Check temperature to ensure thorough reheating without overcooking edges.

Hearty Picks For Breakfast Casserole

  • Cheese and Charcuterie Companion: Pair this hearty breakfast casserole with a crisp cheese board featuring aged cheddar, creamy gouda, and spicy pepper jack. Add some thinly sliced prosciutto and salami to complement the sausage's rich flavors.
  • Wine and Brunch Buddies: Select a light, sparkling prosecco or a crisp mimosa to cut through the casserole's richness. The bubbles and citrus notes will refresh your palate and balance the dish's savory elements.
  • Fresh and Zesty Sidekick: Serve alongside a bright citrus salad with mixed greens, segments of orange, and a tangy vinaigrette. The fresh, acidic flavors will contrast beautifully with the dense, cheesy casserole and add a refreshing element to the meal.
  • Morning Mocktail Magic: Create a refreshing morning drink with freshly squeezed grapefruit juice, a splash of sparkling water, and a sprig of rosemary. This light, herbal beverage will cleanse the palate and provide a sophisticated non-alcoholic option.

Morning Casserole Concepts

  • Low-Carb Cauliflower Base: Replace hash browns with riced cauliflower, creating a keto-friendly version that reduces carbohydrate content while maintaining similar texture and flavor profile.
  • Vegetarian Protein Swap: Substitute sausage with plant-based chorizo or crumbled tofu, adding vegetarian-friendly protein and maintaining the casserole's hearty character.
  • Gluten-Free Adaptation: Ensure all ingredients are certified gluten-free, particularly checking cheese and seasoning labels to accommodate gluten-sensitive individuals without compromising taste.
  • Mediterranean-Style Remix: Incorporate feta cheese, spinach, and sun-dried tomatoes instead of traditional cheeses and peppers, bringing a Mediterranean-inspired flavor transformation to the classic breakfast casserole.

FAQs

  • What type of cheese works best in this breakfast casserole?

Cheddar and pepper Jack cheeses provide the perfect blend of sharpness and spiciness. They melt beautifully and add rich flavor to the casserole.

  • Can I use fresh hash browns instead of frozen?

No, frozen hash browns work best because they have the right moisture content and texture. Fresh hash browns might make the casserole too wet or soggy.

  • Is it okay to use a different type of meat instead of sausage?

Yes, you can substitute with cooked bacon, ground turkey, or ham. Just ensure the meat is fully cooked before adding to the egg mixture.

  • How do I know when the casserole is fully cooked?

The casserole is done when the eggs are set in the center and the hash browns are golden brown. A knife inserted near the center should come out clean, and the top should be lightly browned.
