Spinach and Mushroom Breakfast Casserole
Description
The Spinach and Mushroom Breakfast Casserole features a base of sautéed onions and mushrooms softened in butter, mixed with wilted baby spinach. These vegetables are combined with beaten eggs, cottage cheese, shredded sharp cheddar, and green onions, seasoned with kosher salt and black pepper. The casserole is baked in a greased dish at 350°F until set and golden on top, providing a balanced mix of creamy and savory flavors with a tender texture. The sharpness of cheddar cheese complements the earthiness of the mushrooms and brightness of the spinach.
Its baked form allows it to be sliced and served easily, making it suitable for breakfast or brunch. It pairs well with light sides or fresh fruit when served as part of a meal. The casserole can be prepared ahead and reheated, accommodating meal planning needs.
To save time during preparation, pre-shredded cheese and pre-sliced mushrooms can be used without affecting the outcome. Draining excess liquid from the spinach mixture before combining prevents a soggy casserole, helping maintain its structure and texture.
