How to make this breakfast casserole recipe

I have outlined how to make this breakfast casserole recipe down below. It just requires 5 simple steps!

STEP ONE

Preheat your oven to 350 degrees and grease a large casserole dish with cooking spray and oil.

STEP TWO

Add 1 tbsp olive oil to a pan. Add the bell pepper, onion, scallions and mushrooms. Sauté for 5-7 minutes until almost cooked. Add the mixture to the bottom of the casserole dish.

STEP THREE

Now add in the ground sausage to the pan (If your sausage is not seasoned add 1 tsp fennel seed, 1 tsp garlic powder, 1/2 tsp dried sage, 1/2 tsp salt and pepper.) Or you can add even if it is seasoned. Cook until browned and cooked through, stir in the spinach and cook 1 more minute. Now add to the bottom of a greased dish along with the veggies.

STEP FOUR

In a large bowl whisk the eggs, milk, cheese and seasonings. Then add in the shredded potatoes. Whisk until combined. Pour the egg mixture over veggies and browned sausage. Give the mixture a light stir to combine everything together.

STEP FIVE

Bake at 350 for 40-45 minutes or until the center is set and cooked through.

Veggies. This recipe calls for a mixture of veggies. But what’s great is that they are so versatile and customizable. Feel free to use zucchini, yellow peppers, broccoli, kale or asparagus!

Cheese. This recipe calls for shredded mozzarella cheese. However, you can use any cheese you prefer. Cheddar cheese, pepper jack, or feta are all great options.
