Key Ingredients & Substitutions

Breakfast Sausage: Use either mild or spicy sausage based on your taste. I often go with mild for kids and add some hot sauce later for extra kick!

Eggs: Large eggs are best for this recipe, but if you’re in a pinch, you can use medium eggs. Just adjust the number slightly if needed!

Cheddar Cheese: Shredded cheddar is my go-to for its great melting qualities, but you could also use Monterey Jack or a blend of cheeses for a different flavor.

Bread: White or whole wheat bread works perfectly. You can substitute with bagels or even leftover croissants for a twist! Just cut them into cubes.

How Do You Get a Perfectly Cooked Casserole?

Getting the eggs just right is key for this casserole. Here’s how to make sure it’s baked perfectly:

  • Make sure to mix everything well so the bread absorbs the egg mixture for a consistent texture.
  • Keep an eye on the casserole during the last few minutes. It should be puffed and the cheese golden brown.
  • Let it rest after baking! This helps it set neatly when you cut into it.

4 Ingredient Sausage Breakfast Casserole

Ingredients You’ll Need:

  • 1 pound breakfast sausage (mild or spicy, as preferred)
  • 6 large eggs
  • 2 cups shredded cheddar cheese
  • 4 slices bread (white or whole wheat), cubed

How Much Time Will You Need?

This casserole takes about 10 minutes to prepare and 30-35 minutes to bake, so plan for roughly 45 minutes total from start to sizzling breakfast plate! Perfect for a busy morning when you want something substantial.

Step-by-Step Instructions:

1. Prepare the Oven and Baking Dish:

First, preheat your oven to 350°F (175°C). While it’s heating up, take a 9×9-inch baking dish and lightly grease it with cooking spray or a bit of butter to prevent sticking.

2. Cook the Sausage:

Now, grab a skillet and heat it over medium heat. Add the breakfast sausage and cook it, breaking it up with a spatula. Keep cooking until it’s browned and no longer pink inside (about 5-7 minutes). Once cooked, drain any excess grease and let it cool slightly while you move on to the next step.

3. Mix the Ingredients:

In a large mixing bowl, crack in the 6 eggs and whisk them well until they are fully blended. Then, add the cubed bread and the cooked sausage to the eggs. Sprinkle in half of your shredded cheddar cheese. Gently stir everything together until the bread is coated and the mixture is combined.

4. Pour and Spread:

Transfer the mixture into your greased baking dish, spreading it out evenly so every piece of bread gets a fair share of sausage and cheese. Then, sprinkle the remaining cheese over the top to make it extra cheesy and delicious.

5. Bake the Casserole:

Pop your dish into the preheated oven and let it bake for about 30-35 minutes. You’ll know it’s done when the edges are golden and the eggs are set in the middle. Keep an eye on it so it doesn’t overcook!

6. Cool and Serve:

After baking, take the casserole out and let it sit for a few minutes to cool down a bit. This makes slicing easier. If you like, sprinkle some chopped green onions or herbs on top for a fresh touch before serving.

7. Enjoy!

Now it’s time to dig in! Serve this warm and enjoy your easy, tasty sausage breakfast casserole with family or friends!

Can I Make This Casserole Ahead of Time?

Absolutely! You can prepare the mixture a day ahead, cover it tightly, and refrigerate. When you’re ready to bake, just take it out of the fridge, let it sit for about 20 minutes to come to room temperature, then bake as instructed. This is a great way to save time on a busy morning!

Can I Use Different Types of Bread?

Yes, feel free to experiment! While white and whole wheat bread are classic choices, you can also use sourdough, brioche, or even stale bagels! Just make sure to cut them into cubes for even distribution.

How Should I Store Leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. You can reheat individual portions in the microwave or warm it back up in the oven at 350°F until heated through.

Can I Add Extra Ingredients?

Definitely! You can mix in veggies like bell peppers, onions, or spinach for added nutrition. Just sauté the veggies with the sausage to ensure they’re cooked through before adding them to the egg mixture.
