Ingredients

  • 12 large Eggs, Beaten
  • ½ Cup Half and Half see notes
  • ½ teaspoon Kosher salt
  • ¼ teaspoon black Pepper
  • 2 cups Shredded cheddar cheese
  • 1 tablespoon avocado oil
  • 3 cloves Garlic, minced
  • 8 ounces Mushrooms, sliced
  • 5 ounces fresh spinach
  • 4 Slices Thick cut bacon, cooked and cut into 2 inch pieces

Instructions

  • Pre-heat the oven to 375F (190C) and spray a 9 x 9 (22 x 22cm) casserole with cooking spray
  • In a large mixing bowl, add the eggs, half and half, salt, and pepper.  Whisk thoroughly.  Mix in the cheese.
  • In a large skillet over medium heat, add oil and garlic.  Sauté for 1 minute.  Add in the mushrooms and sauté for 1 minute more.  Finally, add in the spinach and mix in with the mushrooms.  Continue to sauté until the spinach is wilted.  Remove from the heat.
  • Add the spinach and mushrooms to the bowl with the eggs.  Mix to combine. Pour into the greased casserole and lay the bacon pieces on top in a single layer.
  • Bake in the pre-heated oven for 30 minutes or until the casserole is set in the middle.
  • Serve hot, or wrap portions in foil or plastic wrap and store in an airtight container in the fridge up to 1 week.  

Notes

  1. You can easily double this recipe and use a 9 x 13 baking dish.  Bake for 45 minutes or until set.
  2. Half and half: You can definitely use heavy whipping cream instead of half and half if you want a lower carb count, but the calorie count will be higher.  You could also use blended cottage cheese.
  3. You can add cooked sausage or crumbled bacon into the casserole.  I would use ½ pound of breakfast sausage cooked and crumbled, or 6 slices of bacon cooked and crumbled.  Add it to the egg mixture with the mushrooms and spinach.
  4. To check the low carb breakfast casserole for doneness...insert a butter knife into the middle of the casserole and check to see if the egg is set.
  5. This keto breakfast casserole is perfect for freezing.  You can bake the casserole in a foil pan, let cool, cover with aluminum foil and then freeze, or you can bake it, let cool, remove it from the pan, wrap very well in foil (either the entire casserole or individual servings), and freeze.
