Ingredients

• 6 large eggs
• 1 cup milk (whole or 2% for creaminess)
• 1 cup fresh spinach, chopped
• 1 cup mushrooms, sliced (button or cremini work great)
• 1/2 cup crumbled feta cheese
• 1/4 cup grated Parmesan cheese (optional for extra flavor)
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 2 tablespoons olive oil
• Salt and freshly ground black pepper, to taste
• 1/4 teaspoon ground nutmeg (optional)
• Fresh herbs like parsley or dill for garnish (optional)

How To Make Spinach Mushroom Feta Crustless Quiche Recipe

Step 1: Prepare the Vegetables

Heat olive oil in a large skillet over medium heat. Add the finely chopped onion and sauté for about 3-4 minutes until translucent. Stir in the minced garlic and cook for another 30 seconds until fragrant. Add the sliced mushrooms and cook for 5-7 minutes until they release their moisture and turn golden brown. Finally, add the chopped spinach and cook for another 2 minutes until wilted. Remove the skillet from heat and set aside.

Step 2: Preheat the Oven and Prepare the Baking Dish

Preheat your oven to 350°F (175°C). Lightly grease a 9-inch pie dish or an 8×8-inch baking dish with olive oil or non-stick spray to prevent sticking.

Step 3: Whisk the Egg Mixture

In a large mixing bowl, crack the eggs and whisk together with the milk until fully combined. Season with salt, pepper, and the optional nutmeg. This mixture will create the fluffy and tender texture of the quiche.

Step 4: Combine Ingredients

Add the sautéed vegetables into the egg mixture, followed by the crumbled feta cheese and Parmesan if using. Stir gently to combine everything evenly.

Step 5: Pour and Bake

Pour the mixture into your prepared baking dish, spreading it out evenly. Bake for 30-35 minutes or until the quiche is set in the center and lightly golden on top. You can check doneness by inserting a toothpick in the middle — it should come out clean.

Step 6: Cool and Serve

Allow the quiche to cool for 5-10 minutes before slicing. Garnish with fresh herbs if desired, then serve warm or at room temperature. Enjoy!

Expert Tips

• Make sure to squeeze out excess moisture from the cooked spinach and mushrooms to prevent the quiche from becoming soggy.
• Use full-fat milk or a mix of milk and cream for a richer texture.
• Don’t overbake; the quiche will continue to cook slightly as it rests.
• Let the quiche cool completely before storing leftovers to maintain freshness.
• Feel free to add a pinch of chili flakes or smoked paprika for a subtle kick.

Variations and Customizations

• Protein Boost: Add cooked chicken sausage, diced turkey, or tofu for extra protein.
• Cheese Swap: Try goat cheese, ricotta, or shredded mozzarella instead of feta for different flavors.
• Veggie Mix: Incorporate bell peppers, zucchini, or sun-dried tomatoes to customize your quiche.
• Herbs and Spices: Experiment with thyme, basil, or oregano to give your quiche a new twist.
• Make It Vegan: Use a chickpea flour batter and vegan cheese alternatives for a dairy-free version.

How to Store Leftovers

Store any leftover quiche in an airtight container in the refrigerator for up to 3 days. Reheat slices in the microwave for 1-2 minutes or warm them in a preheated oven at 325°F (160°C) for about 10 minutes to retain the best texture. You can also freeze individual slices wrapped tightly in plastic wrap and foil for up to 2 months. To thaw, place in the refrigerator overnight before reheating.
