Egg Casserole

Instructions

1. Preheat oven to 350 degrees. Coat a 9x13-inch casserole dish with cooking spray.
2. In a large skillet, heat oil on high. Add mushrooms; cook, stirring occasionally, until browned, 3–5 minutes. Add spinach, garlic and white parts of green onion. Cook, stirring, until spinach is wilted, about 3 minutes. Season with salt and black pepper, if desired. Arrange vegetables evenly in prepared casserole dish and sprinkle with half of the cheese.
3. In a large bowl, whisk together eggs and milk. Season with salt and black pepper, if desired. Pour evenly over vegetables, then sprinkle with remaining cheese.
4. Bake until eggs are set and edges are slightly golden, 30–40 minutes. Remove from oven and let cool 5 minutes. Garnish with red pepper and remaining green onion. Cut into squares and serve warm.
