Equipment

1 9x13 Casserole Dish

Ingredients

2 frozen chopped spinach 10 oz bags
1 whole onion chopped
5 oz mushrooms chopped
2 tablespoon butter
2 whole eggs
2 cups shredded cheese of choice
1 t salt
½ t pepper
2 t garlic powder

Instructions

Preheat the oven to 375 degrees.
Grease a 9x13 casserole dish and set aside.
In a large skillet, saute the onions in butter over medium heat until soft and translucent.
Add the mushrooms. Saute until the mushrooms are just starting to brown. Season with a touch of salt. Turn off the heat and set aside.
Cook the spinach in the microwave according to the package. Drain the water out of the cooked spinach by squeezing the spinach in a colander over the sink.
Place the spinach into a bowl.
Add the onions and mushrooms to the bowl.
Add the rest of the ingredients and combine.
Pour the mixture into the greased casserole dish. Add more cheese if desired.
Bake for 35 minutes to an hour. The top should look lightly brown and the cheese should be melted.

Notes

This is an easy make-ahead side dish. You can bake it ahead and freeze it or prepare it in advance and then bake it within a day or two.

Store - Once cooled, you can store the casserole in the refrigerator in an airtight container for 4 days.

Freeze - You can also freeze the casserole as a whole or in individual slices. Let it cool and store it in a freezer-safe container or bag. If freezing in slices, separate them by layers of parchment paper. To enjoy it, let it thaw in the fridge overnight before reheating.

Reheat - To reheat, place the casserole into the microwave or bake it again in the oven on low heat until warmed through.
