Mornings in my tiny Bulgarian kitchen always started with the sizzle of onions in a cast-iron pan. My grandmother would hum old folk songs while she stirred, and the smell of eggs and butter would drift through the whole house. That memory is why I believe breakfast shouldn't be complicated—it should be comforting, filling, and simple enough to let you enjoy the day ahead.

Why You'll Love This Recipe
About the Ingredients
6 large eggs
The base of the casserole. Use fresh, free-range if possible. For a richer flavor, substitute with 5 eggs + 1/4 cup milk.
1/2 cup (120ml) whole milk
Adds creaminess and helps the eggs stay fluffy. Any milk works, but whole milk gives the best texture. Use oat milk for a dairy-free option.
1 lb (450g) breakfast sausage
Adds savory, juicy flavor. Choose mild or spicy, or use turkey sausage for a lighter version. If you can't find breakfast sausage, use ground pork with a pinch of sage and thyme.
1 medium onion, diced
Adds sweetness and depth. Use yellow or white onion. Shallots also work well.
1 red bell pepper, diced
Brings color and a slight crunch. Any bell pepper color works. For a smoky twist, use roasted red peppers from a jar.
2 cups (170g) shredded cheddar cheese
Melts beautifully and adds sharpness. Use sharp cheddar for more flavor, or mix with Monterey Jack for extra creaminess.
1/2 teaspoon salt
Enhances all the flavors. Adjust to taste, especially if your sausage is salty.
1/4 teaspoon black pepper
Adds a gentle kick. Freshly ground is best.
1/4 teaspoon garlic powder
Gives a subtle savory note. Use fresh minced garlic (1 clove) if you prefer.
1/4 cup (15g) chopped fresh parsley, for garnish
Adds a fresh, bright finish. Optional, but recommended. Substitute with chives or green onions.
Tips & Tricks
Don't overmix the eggs
Whisk just until the yolks and whites are combined. Overmixing incorporates too much air, making the casserole puff up and then deflate.
Pre-cook your sausage fully
Make sure the sausage is browned and cooked through before adding to the egg mixture. This prevents raw meat in the final dish and adds better flavor.
Let it rest before slicing
After baking, let the casserole sit for 5 minutes. This allows the eggs to set completely, making it easier to cut clean slices.
Pro Tips
Step-by-Step Instructions
1. Preheat and prep
Preheat your oven to 375°F (190°C). Grease a 10-inch oven-safe skillet or baking dish with butter or nonstick spray.
2. Brown the sausage
In the skillet over medium heat, cook the sausage, breaking it into crumbles, until browned and cooked through, about 5-7 minutes. Remove with a slotted spoon and set aside, leaving a little drippings in the pan.
3. Sauté the veggies
In the same skillet, add the diced onion and bell pepper. Sauté over medium heat until softened and fragrant, about 3-4 minutes. This builds flavor and removes excess moisture.
4. Whisk the eggs
In a large bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until well combined but not frothy.
5. Combine everything
Return the cooked sausage to the skillet with the veggies. Spread evenly. Pour the egg mixture over the top, then sprinkle with shredded cheese.
6. Bake to golden
Place the skillet in the preheated oven and bake for 20-25 minutes, until the edges are golden brown and the center is set (a knife inserted comes out clean). The top should be puffed and lightly browned.
7. Rest and serve
Remove from the oven and let rest for 5 minutes. Garnish with fresh parsley, slice, and serve warm.
Delicious Variations
Vegetarian
Skip the sausage and add 1 cup of sautéed mushrooms and 1 cup of spinach. Cook the mushrooms with the onions and peppers.
Southwest
Add 1/2 cup of black beans, 1/2 cup of corn, and a dash of cumin. Use pepper jack cheese instead of cheddar.
Bacon Lover's
Substitute the sausage with 8 slices of cooked, crumbled bacon. Reduce salt slightly as bacon is salty.
How to Store Simple Things To Make For Breakfast
Refrigerator
Store leftovers in an airtight container in the fridge for up to 4 days.
Freezer

Reheating
Reheat in the microwave for 1-2 minutes, or in a 350°F (175°C) oven for 10 minutes until warmed through.
Frequently Asked Questions
Q: Can I make this breakfast casserole ahead of time?
Yes, you can assemble the casserole (without baking) the night before, cover, and refrigerate. In the morning, bake as directed, adding 5-10 minutes to the baking time.
Q: Can I use egg whites instead of whole eggs?
Yes, you can use 8 egg whites instead of 6 whole eggs, but the texture will be slightly less rich and fluffy. Add a tablespoon of olive oil to compensate for the missing fat.
Q: What can I substitute for breakfast sausage?
You can use ground turkey, chicken, or even crumbled tofu for a vegetarian option. Season with sage, thyme, and a pinch of red pepper flakes to mimic sausage flavor.
Q: Can I add potatoes to this casserole?
Yes, add 1 cup of frozen hash browns (thawed) or diced cooked potatoes to the skillet before pouring the eggs. This makes it more filling and adds a nice texture.
Q: Why is my casserole watery?
Watery casserole often happens if your vegetables release too much moisture. Make sure to sauté them until they are soft and any liquid has evaporated. Also, avoid overmixing the eggs, which can incorporate too much air and cause separation.
