• Sausage: Opt for a good-quality breakfast sausage—spicy or mild depending on your preference—crumbled and browned for savory depth.
• Eggs: The main backbone of the Sausage & Egg Keto Breakfast Casserole, creating that signature fluffy texture.
• Heavy Cream: Gives the casserole richness and helps thicken the egg mixture for a custardy bite.

• Bell Pepper: Chopped finely for pops of color and a subtle sweet crunch in every bite.

• Salt and Pepper: Just a pinch brings all the ingredients together, enhancing every single layer.

How to Make Sausage & Egg Keto Breakfast Casserole

Step 1: Prepare and Brown the Sausage

Start by preheating your oven to 375°F (190°C). In a large skillet set over medium heat, cook your breakfast sausage, breaking it up with a spatula until it’s browned and cooked through. Drain any excess fat—this step keeps the casserole light and prevents greasiness.

Step 2: Sauté the Veggies

In the same skillet, toss in the chopped bell peppers and green onions. Sauté them for just a couple of minutes until they’re softened and a little fragrant. Cooking the veggies first coaxes out their sweetness and ensures they’re perfectly tender in the final casserole.

Step 3: Beat the Eggs and Mix the Custard

Crack your eggs into a large mixing bowl and whisk them thoroughly with the heavy cream, salt, and pepper. Take an extra minute to really blend the mixture—a well-beaten custard helps everything puff up beautifully in the oven.

Step 4: Assemble the Casserole

Grab a 9×13-inch baking dish and lightly grease it. Evenly scatter the cooked sausage and sautéed vegetables over the bottom of the dish, then pour the egg mixture right on top. Sprinkle your shredded cheddar cheese (plus any extras, if you’d like) over everything.

Step 5: Bake and Enjoy

Pop the casserole into your preheated oven and bake for about 30–35 minutes, or until the eggs are set and the top is golden brown. Let it cool for a few minutes before slicing. The result? The most irresistible Sausage & Egg Keto Breakfast Casserole, every single time.

How to Serve Sausage & Egg Keto Breakfast Casserole

Garnishes

Top your Sausage & Egg Keto Breakfast Casserole with a sprinkle of fresh herbs like parsley or chives for a vibrant touch. A spoonful of salsa, sour cream, or a dollop of avocado adds wonderful contrast, making each bite pop with flavor.

Side Dishes

This casserole is hearty enough to stand alone, but you can’t go wrong with a simple side salad tossed in vinaigrette, fresh berries, or even a bowl of sliced tomatoes on the side. If you’re feeding a bigger crowd, serve it buffet-style with bacon or a low-carb yogurt parfait.

Creative Ways to Present

Serve the casserole as is for a casual morning, or cut into small squares and arrange them on a platter for brunch gatherings. You can also use muffin tins to create single-serve portions—perfect for grab-and-go breakfasts during a busy week.

Make Ahead and Storage

Storing Leftovers

Let the casserole cool to room temperature before covering it tightly or transferring slices to an airtight container. Store in the refrigerator for up to four days, and simply reheat slices as needed for a quick, comforting meal.

Freezing

Sausage & Egg Keto Breakfast Casserole freezes like a dream. Once it’s cooled, cut into portions, wrap each tightly in plastic wrap, and store them in a freezer bag for maximum freshness. They’ll keep for up to two months—just remember to thaw overnight in the fridge before reheating.

Reheating

To reheat, microwave individual pieces for 1–2 minutes until hot, or warm the entire casserole in a 325°F oven, covered with foil, until it’s heated through. Either way, you’ll get that same fluffy, comforting texture every time.
