Type Meal Prep

This casserole is the ultimate comfort food solution for anyone on a Keto or low-carb diet in the US. We've swapped out the traditional high-carb potato hash browns for fiber-rich riced cauliflower, then loaded it with classic American breakfast sausage, plenty of sharp cheddar, and 10 large eggs. It bakes up hearty, flavorful, and is perfect for meal prep—just bake it on Sunday and reheat slices all week long!



Ingredients

The Base 'Hash' & Protein

  • ✓ 2 bags (10 oz each) Frozen Riced Cauliflower (keep frozen until use)
  • ✓ 1 lb (16 oz) Ground Breakfast Sausage (check label for 0g sugar)
  • ✓ ½ small Yellow Onion, diced
  • ✓ ½ medium Green Bell Pepper, diced

Egg Custard & Cheese

  • ✓ 10 large Eggs
  • ✓ ½ cup Heavy Whipping Cream
  • ✓ 1 tsp Kosher Salt
  • ✓ ½ tsp fresh ground Black Pepper
  • ✓ ½ tsp Garlic Powder
  • ✓ 2 cups Shredded Sharp Cheddar Cheese, divided

Detailed Instructions

  1. 1 Preheat & Prep: Preheat your oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish with butter or avocado oil spray.
  2. 2 Sausage & Veggies: In a large skillet over medium-high heat, add the ground sausage. Break it apart with a spatula. When halfway browned, add the diced onion and green pepper. Cook until sausage is done and veggies are tender (approx. 10 mins). Drain excess grease if excessive.
  3. 3 Thaw cauliflower: Add the frozen riced cauliflower directly to the skillet. Sauté for 3-5 minutes just to thaw and evaporate excess moisture. Do not overcook to avoid mushiness. Remove skillet from heat.
  4. 4 Whisk Eggs: In a large mixing bowl, whisk eggs, heavy cream, salt, pepper, and garlic powder until smooth. Stir in 1.5 cups of shredded cheese.
  5. 5 Combine & Fill: Transfer the sausage/cauliflower mixture to the egg bowl and stir to combine. Pour into the prepared baking dish. Top with the remaining 0.5 cup of cheddar.
  6. 6 Bake: Bake for 35-40 minutes until the edges are golden brown, the cheese is bubbly, and the center is set (does not jiggle). Let rest for 5-10 minutes before slicing.

Keto Meal Prep Tip

Allow casserole to cool completely before slicing into 6 pieces. Store individual slices in airtight containers in the fridge for up to 4 days. Reheat a slice in the microwave for 60-90 seconds on high for a quick, high-protein Keto breakfast on the go!
