How to Make This Keto Breakfast Casserole

Ready to whip up this mouthwatering casserole? Follow these simple steps:
- Brown the Sausage: In a large skillet over medium-high heat, crumble the ground sausage. Cook until no longer pink, stirring occasionally. Drain any excess grease.
- Sauté Vegetables: Add chopped onion and bell pepper to the skillet. Cook until softened, about 5-7 minutes.
- Season the Mixture: Stir in garlic powder, onion powder, salt, and pepper. Mix well and let it cool slightly.
- Whisk Eggs: In a large bowl, whisk eggs until light and frothy.
- Add Dairy and Seasonings: Pour in the heavy cream and almond milk, whisking until combined. Add a pinch of salt and pepper.

Pro Tips for the Perfect Casserole
- Cool Your Mixture: Let the sausage and veggie mixture cool before adding it to the eggs to prevent curdling.

- Check for Doneness: Keep an eye on the casserole as it bakes; ovens vary, so it might take longer for some.
