Ingredients for Easy Keto Breakfast Casserole

Gather these simple ingredients before you begin cooking.

• 8 large eggs
• 1/2 pound (225 g) breakfast sausage, without added sugar
• 1 cup shredded cheddar cheese
• 1/2 cup heavy cream
• 1/2 cup chopped bell pepper
• 1/4 cup chopped onion
• 1/2 teaspoon garlic powder
• 1/2 teaspoon salt, or to taste
• 1/4 teaspoon black pepper
• 1 teaspoon butter or olive oil for greasing the baking dish

Equipment You Will Need

• One medium mixing bowl
• A whisk or fork
• A skillet
• A 9-by-9-inch baking dish
• A spatula or spoon
• An oven

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9-by-9-inch baking dish with butter or olive oil to help prevent the casserole from sticking.

Step 2: Cook the Breakfast Sausage

Place a skillet over medium heat and add the breakfast sausage. Break it into small pieces with a spoon and cook until it is fully browned and reaches a safe internal temperature of 160°F (71°C). Drain excess grease if necessary.

Add the chopped bell pepper and onion. Cook for another 3–4 minutes until the vegetables begin to soften. Remove the skillet from the heat.

Step 3: Whisk the Eggs and Cream

Crack the eight eggs into a large mixing bowl. Add the heavy cream, garlic powder, salt, and black pepper. Whisk everything together until the mixture is smooth and well combined.

Step 4: Add the Sausage and Vegetables

Spread the cooked sausage, bell pepper, and onion evenly across the bottom of your prepared baking dish. Distribute the ingredients so every serving contains a good balance of sausage and vegetables.

Step 5: Add the Cheese

Sprinkle approximately half of the shredded cheddar cheese over the sausage and vegetables. Pour the egg mixture evenly into the baking dish, then sprinkle the remaining cheese over the top.

Step 6: Bake the Casserole

Place the baking dish in the preheated oven. Bake for approximately 30–35 minutes, or until the eggs are fully set and the center reaches 160°F (71°C). Cooking time may vary depending on your oven and the depth of the dish.

If the top begins to brown too quickly, loosely cover the dish with aluminum foil. Always check that the center is fully cooked before removing the casserole from the oven.

Step 7: Let It Rest and Serve

Remove the casserole from the oven and allow it to rest for approximately 5–10 minutes. Cut it into six portions and serve warm. Add fresh parsley or a little extra cheese if desired.

Tips for the Best Keto Breakfast Casserole

• Drain the sausage: Removing excess grease helps prevent a greasy casserole.
• Use freshly shredded cheese: It melts smoothly and gives the casserole a delicious cheesy topping.
• Avoid excess moisture: Cook watery vegetables, such as mushrooms or spinach, before adding them.
• Check the center: The casserole should be fully set before serving.
• Adjust the seasoning: Taste your cooked sausage before adding extra salt.

Easy Variations to Try

1. Keto Bacon Breakfast Casserole

Replace the sausage with cooked, crumbled bacon for a smoky flavor. Check ingredient labels for added sugars if you are following a strict ketogenic diet.

2. Spinach and Cheese Casserole

Replace the sausage with cooked spinach and mushrooms for a vegetarian-friendly variation. Add extra cheddar or mozzarella for a richer flavor.

3. Spicy Keto Breakfast Casserole

Add a pinch of red pepper flakes or a finely chopped jalapeño to give your breakfast a little heat.

4. Broccoli Cheddar Casserole

Add small pieces of lightly steamed broccoli and use extra cheddar cheese for a delicious combination of vegetables and cheese.

What to Serve with Keto Breakfast Casserole

This casserole is filling on its own, but you can serve it with other low-carbohydrate foods to create a complete breakfast.

• Sliced avocado
• Fresh cucumber and tomato salad
• Plain Greek yogurt, if it fits your carbohydrate target
• Sautéed spinach
• Unsweetened tea or coffee

How to Store and Reheat Leftovers

Refrigerator: Allow the casserole to cool slightly, then divide it into airtight containers. Refrigerate within two hours and use within 3–4 days.

Freezer: Freeze individual portions in freezer-safe containers for up to 2–3 months for best quality.

Reheating: Reheat individual portions in the microwave until steaming hot throughout, or warm them in an oven at 325°F (165°C). Reheated egg dishes should reach 165°F (74°C).
