Essential Ingredients for Sausage and Egg Bake

This hearty and satisfying keto breakfast comes together with a handful of simple ingredients.

• Sausage: 1 lb (450g) ground breakfast sausage
• Eggs: 10 large eggs
• Cheese: 2 cups shredded cheddar or Colby Jack cheese, divided
• Dairy: ½ cup heavy cream
• Aromatics: 1 small onion, chopped
• Seasoning: ½ teaspoon salt & ¼ teaspoon black pepper

Ingredients Notes

A little more detail on our key ingredients will ensure your breakfast casserole is perfect.

• The Sausage: For the best flavour, I recommend using a good quality ground breakfast sausage. You can choose a mild, medium, or spicy variety depending on your preference. Be sure to cook and crumble the sausage first and drain off any excess grease before adding it to the casserole.
• The Eggs: Fresh, large eggs form the fluffy, protein-packed base of our casserole. Whisking them well with the heavy cream and seasonings before you bake is key to creating a light and uniform texture.
• The Cheese: A good melting cheese is essential for that gooey, delicious result. A sharp cheddar will provide a bold flavour, while a Colby Jack or a simple mozzarella will give you a fantastic cheese pull. For the best melt, it’s always recommended to shred your own cheese from a block.
• The Heavy Cream: Adding a splash of heavy cream to the whisked eggs is a crucial step for a rich and tender result. It adds a wonderful creaminess and fat content that keeps the baked eggs from becoming dry or rubbery. For a dairy-free option, you could substitute this with full-fat coconut milk.

How to Make Keto-Friendly Sausage and Egg Bake

Let’s walk through the simple steps to create this delicious and satisfying make-ahead breakfast.

• Step 1: Prepare the Oven and Cook the Sausage. First, preheat your oven to 190°C (375°F). Grease a 9×13 inch baking dish. In a large skillet over medium-high heat, cook the ground sausage and the chopped onion, breaking the sausage apart with a spoon, until it is browned and cooked through.
• Step 2: Assemble the Base. Drain off any excess grease from the cooked sausage and onion mixture. Spread the cooked sausage evenly across the bottom of your prepared baking dish. Sprinkle 1 cup of the shredded cheese evenly over the top of the sausage.
• Step 3: Prepare the Egg Mixture. In a large bowl, crack all 10 eggs. Add the heavy cream, salt, and pepper. Whisk everything together vigorously until the mixture is well combined, pale, and slightly frothy.
• Step 4: Pour and Top the Casserole. Carefully pour the whisked egg mixture evenly over the sausage and cheese in the baking dish. Sprinkle the remaining 1 cup of shredded cheese all over the top.
• Step 5: Bake to Golden Perfection. Place the baking dish in the preheated oven. Bake for 30-35 minutes, or until the eggs are set in the center and the cheese on top is melted and beautifully golden brown.
• Step 6: Rest, Slice, and Serve. Let the casserole rest for at least 5-10 minutes before you slice into it. This allows the eggs to set up completely, making it much easier to serve clean slices. Serve warm.

Storage Options

This sausage and egg bake is an absolute dream for meal prepping. Once the casserole has cooled completely, you can either cover the entire dish tightly or slice it into individual portions and place them in airtight containers. It will stay fresh and delicious in the refrigerator for up to 5 days, making your weekday breakfasts incredibly easy.

This casserole also freezes wonderfully. You can wrap the individual cooled slices in plastic wrap and then place them in a freezer-safe bag. They will keep in the freezer for up to 3 months, and you can reheat them directly from frozen in the microwave for a lightning-fast breakfast.

Variations and Substitutions

This simple keto casserole is a fantastic base that you can easily customize with your favourite low-carb ingredients. You can easily swap the breakfast sausage for cooked and crumbled bacon, diced ham, or even some ground beef. Feel free to add some keto-friendly vegetables to the mix, like sautéed mushrooms, chopped bell peppers, or some wilted spinach (be sure to squeeze it very dry!). For a different flavour, you could use a spicy Pepper Jack cheese or a nutty Gruyère instead of the cheddar.

Practical & Valuable Tips

For the best flavour, be sure to brown your sausage well before adding it to the casserole; those caramelized bits add a huge amount of taste. To prevent your casserole from sticking to the dish, be sure to grease your baking dish very generously with butter or a non-stick spray. Finally, you can check if the casserole is done by inserting a knife into the center; if it comes out clean, your eggs are perfectly set.

Frequently Asked Questions

1. My breakfast casserole has a watery layer at the bottom. Why did that happen? A watery casserole is usually because the vegetables or meat released a lot of moisture during baking. If you add vegetables like mushrooms or spinach, it’s very important to cook them first and drain them well. Also, be sure to thoroughly drain off all the excess grease after you cook your sausage.
2. Can I use a different kind of sausage, like Italian sausage? Yes, absolutely! Italian sausage would be a fantastic and flavourful choice for this casserole. Just be sure to remove it from its casings before you cook and crumble it in the skillet.
3. Do I have to pre-cook the sausage before baking the casserole? Yes, it is a crucial step. Pre-cooking the sausage ensures that it is cooked through properly and allows you to drain off the excess fat, which prevents the final casserole from being overly greasy.
4. Can I assemble this casserole the night before and bake it in the morning? Of course! This is a great make-ahead strategy. Simply assemble the entire casserole as directed, cover it tightly with plastic wrap or foil, and store it in the refrigerator overnight. In the morning, you may just need to add about 10-15 minutes to the baking time since you are starting with a cold dish.
5. How do I know when the egg bake is fully cooked in the center? The best way to tell is by giving the dish a gentle shake; the center should be firm and not jiggle. You can also insert a knife into the very center of the casserole. If the knife comes out clean with no wet, uncooked egg on it, your casserole is perfectly baked and ready to rest.
