Ingredients
Vegetables and Aromatics
- 1 tablespoon vegetable oil
- 1 medium onion, chopped
- 1 (10 ounce) package frozen chopped spinach, thawed, drained, and squeezed dry
Egg Mixture
- 5 large eggs, beaten
- ¼ teaspoon salt
- ⅛ teaspoon ground black pepper
Cheese
- 3 cups shredded Muenster cheese
Instructions
- Preheat and prepare pan: Preheat your oven to 350 degrees F (175 degrees C) and lightly grease a 9-inch pie pan to prevent sticking.
- Sauté onions: In a large skillet over medium-high heat, heat the vegetable oil. Add the chopped onion and cook, stirring occasionally, until the onion softens, about 3 minutes.
- Cook spinach: Add the thawed, drained, and squeezed-dry frozen chopped spinach to the skillet with the onions. Continue cooking, stirring, until all excess moisture has evaporated from the spinach mixture.
- Mix eggs and season: In a large bowl, whisk together the beaten eggs, salt, and ground black pepper until well combined.
- Combine ingredients: Add the cooked spinach and onion mixture along with the shredded Muenster cheese into the bowl with the eggs. Stir gently until all ingredients are evenly blended.
- Transfer to pan: Pour the egg, spinach, onion, and cheese mixture into the prepared 9-inch pie pan, spreading evenly.
- Bake: Place the pan in the preheated oven and bake for about 30 minutes, or until the eggs have fully set and the top is lightly golden.
- Cool and serve: Remove the quiche from the oven and let it cool for 10 minutes before slicing and serving warm. Enjoy your crustless spinach quiche!
Notes
- Be sure to squeeze out as much moisture as possible from the thawed spinach to prevent a soggy quiche.
- You can swap Muenster cheese with other mild cheeses like mozzarella or Swiss if preferred.
- This quiche is naturally gluten-free as it contains no crust.
- Leftovers can be refrigerated and enjoyed cold or reheated the next day.
- For a richer flavor, consider adding a pinch of nutmeg or garlic powder to the egg mixture.
