What is the difference between a frittata and a breakfast casserole?
Frittatas are cooked on the stove in a cast-iron skillet and then finished in the oven. Breakfast casseroles are baked in the oven in a large baking dish.
Breakfast Casserole Ingredients
- Sausage: Buy turkey breakfast sausage, like Jennie-O.
- Spinach adds color and vitamins and minerals, like vitamin C, calcium, and iron.
- Eggs: You’ll need a dozen large eggs.
- Milk: Whole or reduced-fat milk will work.
- Cheese: Shredded part-skim mozzarella and grated parmesan cheese
- Salt and Pepper season the egg casserole.
- Sundried Tomatoes: Drain and finely chop a quarter cup of sundried tomatoes in oil.
How to Make Breakfast Casserole
- Cook the sausage in a skillet on medium-high heat and then transfer to a bowl.
- Sauté the spinach on medium heat in the oil from the sausage. Remove it with a slotted spoon and squeeze out any excess liquid. Next, chop the spinach.
- Egg Mixture: Whisk the eggs in a medium bowl. Add the milk, a cup of mozzarella, two tablespoons of parmesan, salt, and pepper.
- Assemble the Casserole: Layer the sausage, spinach, and tomatoes in a 9” x 13” casserole dish coated with cooking spray. Pour the eggs over the top and sprinkle with the remaining cheese.
- Bake the breakfast casserole at 350°F for 35 minutes until browned.
Variations
- Meat: Swap sausage with bacon.
- Vegetarian Breakfast Casserole: Omit the sausage and add another vegetable.
- Leafy Greens: Substitute Swiss chard or kale for the spinach.
- Vegetables: Add other veggies, like bell peppers, mushrooms, or onions.
- Cheese: Replace parmesan with Pecorino Romano and mozzarella with Swiss.
- Seasoning: Add onion or garlic powder or dried herbs, like oregano or rosemary, to the eggs.
