Ingredients List
Gathering the right ingredients is key to the Easy Keto Sausage & Egg Breakfast Casserole Recipe. Here’s what you’ll need:
Main Ingredients:
- 1 pound breakfast sausage (mild or spicy; use turkey sausage for a lighter version)
- 8 large eggs (pasture-raised for best flavor)
- 1 cup shredded sharp cheddar cheese (swap in mozzarella, gouda, or pepper jack for a twist)
- ⅓ cup heavy cream (or coconut cream for dairy-free option)
- ½ cup diced bell peppers (mix red and green for color and crunch)
- ¼ cup chopped green onions (or chives)
- Salt and pepper, to taste
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
Optional Add-Ins:
- 1 cup chopped fresh spinach (adds color and nutrients)
- ¼ cup crumbled feta (for a Greek-inspired flavor)
- Sliced mushrooms (for a deeper umami punch)
Ingredient Tips:
For bold flavor, try using chorizo or Italian sausage in place of breakfast sausage. Cheese lovers can add extra or mix two types for a melty, gooey result. Prefer a plant-based touch? Toss in cooked vegan sausage or check out Asian Style Tuna Cakes for another protein-rich breakfast alternative.

Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with butter, olive oil, or coconut oil. This ensures easy serving and prevents sticking.
Step 2: Brown the Sausage
Crumble and cook sausage in a large skillet over medium heat until golden brown and cooked through (about 6-7 minutes). Drain excess grease for a lighter casserole. For extra flavor, sauté the sausage with bell peppers and optional mushrooms.
Step 3: Whisk the Eggs
In a large mixing bowl, whisk together eggs, heavy cream, garlic powder, onion powder, salt, and pepper until well combined and slightly frothy. The cream delivers unbeatable richness and keeps the eggs super moist.
Step 4: Layer the Ingredients
Spread the cooked sausage mixture evenly on the bottom of your prepared casserole dish. Sprinkle shredded cheese, green onions, and any optional add-ins (like spinach) over the top for layered flavor and texture.
Step 5: Pour and Gently Mix
Carefully pour the whisked egg mixture over layered ingredients. Gently shift the dish or use a fork to ensure eggs seep into every corner—this step guarantees no dry bites!
Step 6: Bake to Perfection
Bake the casserole uncovered for 30-35 minutes, or until the center sets and a knife inserted comes out clean. If you love a cheesy crust, sprinkle extra cheese on top during the last 5 minutes of baking.
Step 7: Rest and Serve
Let the casserole rest 5–10 minutes before slicing. This allows the proteins to set and makes for ultra-clean portions.
