Easy Mushroom & Swiss Breakfast Casserole Recipe


This breakfast casserole features layers of sautéed mushrooms, Swiss cheese, and eggs baked to perfection. It takes about 1 hour from start to finish and serves 6 people.
Ingredients
- 8 slices of bread, cubed
- 2 cups fresh mushrooms, sliced
- 1 cup shredded Swiss cheese
- 6 large eggs
- 2 cups milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1 tablespoon olive oil
- Chopped fresh parsley for garnish (optional)
Instructions
- Prep the Ingredients: Preheat the oven to 350°F (175°C). Cube the bread and slice the mushrooms.
- Sauté the Mushrooms: In a skillet, heat olive oil over medium heat. Add the sliced mushrooms and sauté until they are tender and browned, about 5-7 minutes.
- Assemble the Casserole: In a greased 9×13 inch baking dish, layer the cubed bread, sautéed mushrooms, and shredded Swiss cheese.
- Mix the Egg Mixture: In a bowl, whisk together the eggs, milk, salt, pepper, and garlic powder. Pour the egg mixture evenly over the bread and mushroom layers.
- Bake: Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the eggs are set and the top is golden brown.
- Serve: Let the casserole cool for a few minutes before slicing. Garnish with chopped parsley if desired and serve warm.
