Ingredients
- 1 lb breakfast sausage pork, chicken, or turkey - no sugar added for strict keto

- 1 tsp garlic powder
- Salt & pepper to taste
Instructions
- Preheat oven to 375°F.
- Grease a 9x13 baking dish with butter or avocado oil.
- In a skillet, brown and crumble the sausage.
- Drain grease, then spread sausage evenly in the baking dish.
- In a large bowl, whisk eggs, heavy cream, garlic powder, salt, and pepper.
- Stir in 1/2 cup cheddar and all of the mozzarella.
- Pour egg mixture over sausage.
- Sprinkle the remaining 1/2 cup cheddar on top.
- Bake 35-40 minutes, until center is set and top is golden.
- Let cool 5-10 minutes before slicing. Serve warm.
Notes
- Make it ahead: Assemble the casserole the night before, cover, and refrigerate. In the morning, bake as directed (you may need to add 5–10 minutes to the bake time).
- Customize it: Try swapping in hot sausage for a spicy version, or add veggies like onions, mushrooms, or peppers for variety.
- Cheese swaps: Cheddar and mozzarella make it extra gooey, but feel free to use Swiss, gouda, or pepper jack for different flavors.
- Meal prep tip: Slice cooled casserole into squares, store in airtight containers, and reheat for quick weekday breakfasts.
- Freezer-friendly: Bake, cool completely, slice, and wrap portions individually. Freeze up to 2 months and reheat in the oven or microwave.
