A delicious and satisfying keto-friendly breakfast casserole loaded with eggs, cheese, sausage, and fresh vegetables. Perfect for meal prep or a hearty morning meal that’s low in carbs and high in flavor.

  • Total Time: 50 minutes
  • Yield: 8 servings

Ingredients

Egg Mixture

  • 8 large eggs
  • 1 cup heavy cream
  • 1 teaspoon garlic powder
  • Salt and pepper to taste

Filling

  • 1 cup shredded cheddar cheese
  • 1/2 cup cooked sausage, crumbled
  • 1/2 cup diced bell peppers
  • 1/4 cup chopped green onions

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it reaches the perfect temperature for baking the casserole evenly.
  2. Mix Eggs and Cream: In a large mixing bowl, whisk together the 8 large eggs, 1 cup heavy cream, 1 teaspoon garlic powder, salt, and pepper until fully combined and slightly frothy.
  3. Add Fillings: Stir in the 1 cup shredded cheddar cheese, 1/2 cup cooked and crumbled sausage, 1/2 cup diced bell peppers, and 1/4 cup chopped green onions until evenly distributed in the egg mixture.
  4. Prepare Baking Dish: Grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking, then pour the egg mixture into the dish, spreading it out evenly.
  5. Bake: Place the baking dish in the preheated oven and bake for 35 minutes or until the eggs are fully set and the top is a nice golden brown color.
  6. Cool and Serve: Allow the casserole to cool for about 5 minutes before slicing. This helps it set further and makes serving easier.

Notes

  • You can substitute sausage with bacon or ham for a different flavor profile.
  • Use full-fat cheddar cheese for best keto results.
  • If you want extra veggies, add spinach or mushrooms, but keep the portions moderate to maintain keto macros.
  • Let the casserole cool completely before refrigerating if making ahead. Reheat gently before serving.
  • For a dairy-free version, replace heavy cream with coconut cream and cheddar cheese with a dairy-free cheese alternative.
