Protein
- 16 ounces breakfast sausage (see Notes)

Dairy
- ¾ cup heavy cream

- ½ teaspoon kosher salt

How to Make Sausage & Egg Keto Breakfast Casserole
Step 1: Preheat the Oven
Preheat your oven to 375° Fahrenheit. Lightly grease your baking dish with oil or butter to prevent sticking. Layer the fresh spinach leaves at the bottom of the dish, followed by the white parts of the scallions and chopped parsley.
Step 2: Cook the Sausage
In a large skillet over medium heat, add the breakfast sausage. Cook until browned and crumbled, stirring often. Use a spatula or wooden spoon to break the sausage into small pieces while cooking.
Step 3: Prepare the Egg Mixture
While the sausage cooks, take a large mixing bowl and whisk together the eggs, heavy cream, garlic powder, kosher salt, and black pepper until fully combined. Once mixed well, gently fold in the shredded cheddar cheese until evenly distributed.
Step 4: Layer Ingredients in Baking Dish
Once your sausage is cooked through, layer it on top of the spinach mixture in your baking dish. Carefully pour the egg mixture over the sausage, ensuring it’s spread evenly across all layers.
Step 5: Bake
Place your baking dish in the preheated oven. Bake for about 20 to 25 minutes or until the casserole is firm and eggs are cooked through. Once done, remove from oven and slice into squares. Garnish with green parts of scallions and additional shredded cheese if desired before serving warm.
