Ingredients
Method
- Preheat oven to 375°F (190°C) and grease a 9-inch square baking dish.
- In a large bowl, whisk together eggs, cottage cheese, milk, salt, and pepper until smooth. Whisk in flour and baking powder, then stir in cheddar.
- Fold in spinach, bell pepper, onion, and sausage (if using) until evenly mixed. Pour the batter into the prepared dish.
- Bake 35 to 40 minutes, until puffed, golden, and the center feels set with a slight jiggle. Let cool 5 minutes before slicing.
- Slice into squares and serve warm.
Notes
For a make-ahead option, assemble the unbaked casserole, cover, and refrigerate overnight. Bake straight from the fridge the next morning, adding 5 to 10 minutes to the time listed.
