How to Make Keto Breakfast Casserole
STEP 1. Preheat the oven. Set it to 400°F and lightly grease a square 9-inch baking dish.
STEP 2. Whisk the egg mixture. In a large bowl, whisk together the eggs, heavy cream, salt, pepper, garlic powder, and red pepper flakes.
STEP 3. Add cheese. Use a rubber spatula to fold in ½ cup of the shredded cheddar cheese. Set the mixture aside.
STEP 4. Cook the sausage. Heat a large 12-inch skillet over medium-high heat and add the raw sausage, cooking it for 5-7 minutes while breaking it up until it’s browned with no need to drain the fat.
STEP 5. Add spinach. Turn off the heat and mix in the whole spinach leaves until they are slightly wilted.
STEP 6. Assemble the casserole. Transfer the sausage and spinach mixture into the greased baking dish, spreading it evenly across the bottom.
STEP 7. Pour the egg mixture. Remix the eggs and pour over the sausage. Gently stir if needed to ensure even distribution.
STEP 8. Add remaining cheese. Sprinkle the rest of the shredded cheddar cheese on top.
STEP 9. Bake the casserole. Place it in the oven and bake until the eggs are set and the cheese is golden brown, around 25 minutes.
STEP 10. Rest before serving. Allow the casserole to cool for 10 minutes before cutting it into squares and serving.
