Recipe Information
Ingredients
- 4 cups Frozen hash browns
- 4 cups Fresh spinach
- 6 large Eggs
- 1 cup Milk
- 2 cups Shredded cheddar cheese
- 0.5 cups Grated Parmesan cheese
- 1 medium Yellow onion
- 2 cloves Garlic cloves
- 2 tablespoons Olive oil
- 2 tablespoons Butter
- 1 teaspoon Salt
- 0.5 teaspoons Black pepper
- 0.25 teaspoons Crushed red pepper flakes (optional)
Instructions
Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with butter or cooking spray.
In a large skillet, heat the olive oil over medium heat. Finely chop the onion and mince the garlic, then sauté them in the skillet until the onion is translucent, about 3-4 minutes.
Add the fresh spinach to the skillet and cook until it is wilted, about 2-3 minutes. Remove the skillet from heat and set aside.
In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and red pepper flakes (if using).
Stir in 1.5 cups of shredded cheddar cheese and the grated Parmesan cheese into the egg mixture.
Melt the butter in a separate skillet over medium-high heat. Add the frozen hash browns and cook until lightly golden and crispy, about 5-7 minutes. Transfer the hash browns to the prepared baking dish, spreading them out evenly.
Spread the cooked spinach and onion mixture over the hash browns in an even layer.
Pour the egg and cheese mixture over the spinach and hash browns, ensuring it evenly coats the ingredients.
Sprinkle the remaining 0.5 cup of shredded cheddar cheese on top.
Bake in the preheated oven for 35-40 minutes, or until the casserole is set and the top is golden brown.
Remove from the oven and let it cool slightly for 5 minutes before serving. Enjoy your Hash Browns and Spinach Casserole!
