• ½ teaspoon black pepper
• ½ teaspoon paprika
• 1 teaspoon Italian seasoning

Equipment Needed

• 8×8-inch or 9×9-inch baking dish
• Mixing bowl

• Nonstick cooking spray
• Spatula

Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease an 8×8-inch baking dish with nonstick cooking spray or butter.

Step 2: Cook the Sausage

In a skillet over medium heat, cook the sausage until browned and fully cooked, about 6–8 minutes.

Drain any excess grease and allow it to cool slightly.

Step 3: Whisk the Eggs

In a large mixing bowl, whisk the eggs until smooth.

If using optional seasonings, whisk them into the eggs.

Step 4: Assemble

Spread the cooked sausage evenly in the prepared baking dish.

Pour the beaten eggs over the sausage.

Sprinkle the shredded cheddar cheese evenly on top.

Step 5: Bake

Bake for 22–25 minutes, or until:

• The eggs are fully set.
• The center no longer jiggles.
• The cheese is melted and lightly golden.

A knife inserted in the center should come out clean.

Step 6: Cool and Serve

Allow the casserole to cool for 5 minutes.

Slice into 6 squares.

Garnish with chopped green onions or fresh parsley if desired.

Serve warm.

Tips for the Best Baked Breakfast

Use Fresh Eggs

Fresh eggs provide the fluffiest texture.

Drain the Sausage

Removing excess grease keeps the casserole from becoming oily.

Don’t Overbake

Remove from the oven as soon as the eggs are set to keep them tender and moist.

Shred Your Own Cheese

Freshly shredded cheese melts better and gives the best flavor.

Flavor Variations

Bacon & Cheddar

Replace the sausage with cooked, crumbled bacon.

Ham & Swiss

Use diced ham and shredded Swiss cheese.

Mexican Style

Add taco seasoning and use Pepper Jack cheese.

Serve with salsa and avocado.

Serving Suggestion

Pair this baked breakfast with fresh fruit, sliced avocado, or a simple green salad for a balanced meal. Add a side of salsa or hot sauce for extra flavor.

Chef’s Secret

For an extra fluffy texture, whisk the eggs vigorously for about 1 minute to incorporate air before combining them with the other ingredients. Allow the casserole to rest for 5 minutes after baking so it slices neatly and retains its moisture. A sprinkle of fresh herbs just before serving adds a burst of freshness and color.
