Ingredients

  • drizzle of oil
  • ½ cup onion
  • 1 Tbsp garlic minced
  • 1 lb breakfast sausage
  • 12 eggs
  • ½ cup milk of choice
  • 2 tsp mustard powder
  • 1 tsp oregano
  • ¼ tsp salt
  • pepper to taste
  • cups broccoli florets
  • 1 zucchini diced
  • 1 red bell pepper diced
  • or 3-4 cups veggies of choice

Optional Mix-In:

  • shredded cheese

Instructions

  • Preheat oven to 375°F (190°C).
  • In a skillet over medium heat, add a drizzle of oil and sauté onion and garlic.
  • Once transparent, add sausage and cook until browned, 7-10 minutes.
  • Add to a 13x9-inch casserole or baking dish and set aside.
  • In a large bowl, whisk together eggs, milk of choice, and seasonings. Stir in chopped veggies.
  • Pour mixture over sausage. (Feel free to sprinkle on some shredded cheese, if desired!)
  • Bake until firm and cooked through, 30-40 minutes.
  • Allow to cool slightly before slicing into squares, serving, and enjoying!
  • Store leftovers in the fridge for up to 5 days, and reheat individual portions in the microwave.
  • Yields 12 servings (depending on size of cut).

To freeze baked breakfast casserole:

  • Prepare and bake as described above, then allow to cool completely. Feel free to cut casserole into portions, or you can freeze the entire thing!
  • For portions: package casserole pieces into airtight containers or freezer-safe bags and store in the freezer. (You can package each piece individually, or however many pieces you’ll want to thaw at a time.)
  • To freeze the entire casserole: cover baking dish with an airtight lid and freeze.
  • Lasts in the freezer for up to 3 months.

To reheat baked & frozen casserole:

  • On the night before you want to eat, transfer frozen casserole dish or desired portions to the fridge to thaw overnight.
  • To reheat entire casserole, bake at 350°F (180°C) for 15-20 minutes
  • Reheat individual portions in the oven for 8-10 minutes, or in the microwave for 2-3 minutes, until warmed through. (Oven is better for texture!)

To freeze unbaked breakfast casserole:

  • Prepare ingredients and add everything to your casserole dish.
  • Cover dish with plastic wrap and then foil, and freeze.
  • The day before you want to eat, transfer casserole dish to the fridge and allow to thaw overnight.
  • Before cooking, remove dish from fridge and let sit on the counter for 30 minutes.
  • Bake at 375°F (190°C) for 30-40 minutes.
