How to Make Breakfast Casserole
Follow these simple steps to prepare this delicious Breakfast Casserole:
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and grab out your favorite baking dish. Give it a light spray with nonstick cooking spray so your masterpiece doesn’t stick around for too long after cooking.
Step 2: Brown the Sausage
In a skillet over medium heat, cook the sausage until it’s beautifully browned, using a spatula to crumble it as it cooks. This step not only enhances the flavors but also fills your kitchen with a delicious aroma that’s sure to wake up anyone still snoozing.
Step 3: Sauté the Veggies
Once your sausage is perfectly cooked, add the diced bell peppers and chopped onion to the skillet. Sauté these colorful veggies for about 5 minutes until they soften and the onions become translucent. You’re officially making magic happen in that pan!
Step 4: Whisk Together Eggs and Milk
In a large bowl, whisk together the eggs and milk until well combined. Season generously with salt and pepper; this mixture is the key to a flavorful casserole, so don’t be shy!
Step 5: Combine Ingredients
Now, mix in the sautéed sausage and half of the shredded cheese with your egg mixture. Pour this delightful concoction into your prepared baking dish, spreading it evenly. Top it off with the remaining cheese for that ooey-gooey finish.

Place your dish in the preheated oven and let it bake for 30-35 minutes. You’ll know it’s done when it’s set in the middle and golden brown on top. At this point, feel free to show off your casserole’s beauty to anyone who isn’t already in the kitchen drooling!
