I grew up eating this at most of the family holiday’s with the maternal side of my family. But, we called it spinach casserole. As a child, I hated spinach, and no, it don’t not matter that Popeye ate all of his. As far as I was concerned, we could send him mine as well. I, would take a spoon full of the cheese and mushrooms.
1 lb fresh mushrooms
2 packages frozen spinach
1 teaspoon salt
1/4 cup chopped onion
1/4 cup melted butter
serves 6-8 people 1 cup freshly grated cheddar cheese
Wash and dry mushrooms. Slice off stems. Saute’ stems and caps until brown, browning the cap side of mushroom first. Cook spinach according to package and strain excess liquid from spinach. Line a shallow 10″ casserole dish (about 1 1/2″ deep) with the spinach. Season with salt, chopped onion and melted butter.
Sprinkle with 1/2 cup of cheddar cheese. Arrange the sautéed mushrooms (caps and stems) over the spinach. Season with garlic salt. Cover with remaining cheese. Bake for 20 minutes at 350 degrees, or until cheeses is melted and browned. Casserole may be prepared in advance.
