I love spinach, This casserole is a favorite because you can put it together ahead of time and it's a side dish that goes with anything, steaks, roasts, chicken. I love leftovers for lunch the next day. It's like a quiche without the crust.
Easy to mix together.
Cook onion in butter in microwave.
Combine melted butter and breadcrumbs.
2 packages frozen chopped spinach, thawed and drained
1/2 stick butter
1/2 C chopped onion
1/2 t salt
1/8 t pepper
1/8 t nutmeg
1 can cream of mushroom (or celery) soup
1/2 C shredded cheddar cheese
topping: 1/4 C breadcrumbs
2T butter, melted
Squeeze excess water from the spinach. Combine butter and onion in large bowl and microwave about 2 or 3 minutes until the onion is tender. Stir in spinach, mix in eggs, seasonings, soup and cheese. Combine well and pour into a buttered casserole or deep 9" pie dish. Combine topping mix and sprinkle on top. Cover and refrigerate at this point or bake now at 350 for 30-40 minutes until slightly puffed.
