Ingredients
Vegetables
- 3 cups spinach leaves (fresh, uncooked)
- 4 scallions (sliced, white and green parts separated)
- ¼ cup chopped fresh parsley
Protein
- 16 ounces breakfast sausage (see Notes)
- 12 large eggs
Dairy
- ¾ cup heavy cream
- 2 cups freshly shredded cheddar cheese (see Notes)
Seasonings
- ½ teaspoon garlic powder
- 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 to prevent sticking. Then, layer the spinach leaves at the bottom of the dish along with the white parts of the scallions and chopped parsley. Set the dish aside.
Step 2: Cook the Sausage
In a large skillet over medium heat, cook the breakfast sausage until it’s browned and crumbled. Stir often to break up the sausage into small pieces using a spatula or wooden spoon.
Step 3: Prepare Egg Mixture
While the sausage cooks, whisk together the eggs, heavy cream, garlic powder, kosher salt, and black pepper in a large mixing bowl. Once combined thoroughly, gently fold in the shredded cheddar cheese.
Step 4: Assemble Casserole
Layer the cooked sausage over the spinach leaves in your baking dish. Pour the egg mixture evenly over the sausage, ensuring all areas are covered.
Step 5: Bake
Place your baking dish in the preheated oven. Bake for 20 to 25 minutes or until the casserole is firm and eggs are fully cooked through. Once done, remove from oven and slice into 12 squares. Garnish with green parts of scallions or additional shredded cheese if desired before serving warm.

- Skipping Fresh Ingredients: Using wilted or old spinach can affect the flavor and texture. Always choose fresh, vibrant vegetables for the best taste.
- Overcooking Sausage: Cooking sausage too long can dry it out. Aim for a perfect golden brown without burning to keep it juicy.
- Not Whisking Eggs Properly: Failing to whisk eggs thoroughly leads to uneven texture. Make sure to mix them until fully blended before adding other ingredients.
- Ignoring Cheese Quality: Using pre-shredded cheese may contain anti-caking agents that affect melting. Opt for freshly shredded cheese for better results.
- Inaccurate Baking Time: Not checking doneness can result in undercooked or overcooked casseroles. Use a toothpick or knife to test if the eggs are firm before removing from the oven.
