Ingredients Breakdown

One of the best things about this recipe is its short ingredient list. Let’s take a closer look at each one and why it matters.

1. Crescent Rolls

Crescent rolls serve as the base of this casserole, replacing traditional bread or potatoes. When baked, they become tender yet sturdy enough to support the layers above.

Tip: Make sure to press the seams together so the egg mixture doesn’t leak underneath.

2. Mild Breakfast Sausage

Breakfast sausage adds bold, savory flavor and makes the casserole filling and satisfying.

Tip: Mild sausage works best for a crowd, but you can choose hot sausage if you like extra spice.

3. Eggs

Eggs are the backbone of the casserole, creating structure and a fluffy, custard-like consistency once baked.

Tip: Beating the eggs well helps ensure even cooking and a light texture.

4. Shredded Cheddar Cheese

Cheddar cheese brings sharpness, creaminess, and that classic cheesy pull everyone loves.

Tip: Freshly shredded cheese melts more smoothly than pre-shredded, but either works.

Step-by-Step Instructions

Follow these simple steps for guaranteed success with your Easy Cheesy Breakfast Casserole (4 Ingredients).

1. Preheat the Oven
   Preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with nonstick cooking spray.

2. Cook the Sausage
   In a skillet over medium heat, brown the breakfast sausage until fully cooked. Break it into crumbles as it cooks. Drain excess grease and set aside.

3. Prepare the Crescent Roll Base
   Unroll the crescent rolls and press them evenly into the bottom of the prepared baking dish. Seal any seams to create a solid base.

4. Layer the Sausage
   Sprinkle the cooked sausage evenly over the crescent roll layer.

5. Add the Eggs
   Pour the beaten eggs evenly over the sausage layer, making sure they spread to the edges.

6. Top with Cheese
   Generously sprinkle shredded cheddar cheese over the top.

7. Bake
   Bake for 30 minutes, or until the eggs are fully set and the top is golden and bubbly.

8. Rest and Serve
   Let the casserole cool for a few minutes before slicing. Serve warm and enjoy.

Helpful Tips for the Best Results

Even though this recipe is simple, these tips will help you get perfect results every time.

• Don’t overbake: Overbaking can make the eggs dry. Remove the casserole as soon as the center is set.

• Use foil if needed: If the top browns too quickly, loosely cover it with foil during the last 5–10 minutes.

• Season lightly: The sausage and cheese are already salty, so only add extra seasoning if needed.

• Let it rest: Allowing the casserole to cool slightly makes slicing easier and helps the layers set.
