Ingredient Notes & Substitutions
- Spinach: Fresh spinach can be used; just chop and wilt before using (1 lb fresh ≈ 10 oz frozen).
- Cottage Cheese: Can substitute with ricotta for a different texture.
- Cheese: Use mozzarella for a milder flavor or Swiss/Monterey Jack for a nutty twist.
- Optional Extras: Try adding a pinch of nutmeg, chopped mushrooms, bell peppers, or a little garlic for extra depth.
Step-by-Step Instructions
- Prepare the Spinach
Thaw frozen chopped spinach and squeeze thoroughly to remove excess moisture. Proper draining is crucial to prevent a watery casserole.
- Sauté the Onion
In a skillet, melt the butter over medium heat. Add the chopped onion and sauté until translucent and soft, about 3–4 minutes. This provides sweetness and aromatic flavor.
- Mix the Casserole Base
In a large bowl, combine the cottage cheese, eggs, flour, sautéed onion (with any melted butter), and half of the grated cheese. Stir until well blended. Season with salt and pepper.
- Incorporate the Spinach
Add the well-drained spinach to the mixture, ensuring even distribution. Stir until everything is combined.
- Preheat and Prepare the Dish
Preheat your oven to 350°F (175°C). Grease a baking/casserole dish (about 9×13-inch or a similar size) with butter or nonstick spray for easy release.
- Assemble and Top
Spread the spinach mixture evenly in the prepared dish. Sprinkle with the remaining grated cheese to create a golden, bubbly crust.
- Bake
Bake uncovered for about 30–40 minutes or until the casserole is set in the center and the top is golden and slightly crisp. Ovens may vary, so check at 30 minutes.
- Cool and Serve
Let the casserole cool for 5–10 minutes before serving. This helps the dish set for neater slices.
