Ingredients You’ll Need

10 oz. box frozen chopped spinach, thawed and squeezed: Essential for that classic quiche texture and flavor. Fresh spinach can be used if you prefer; just wilt it before adding.
8 oz. mushrooms, sliced: Adds a hearty, earthy flavor. Button mushrooms work well, but feel free to experiment with shiitake or cremini for a gourmet twist.
1 garlic clove, minced: Infuses the dish with aromatic flavor, enhancing the overall taste.
⅛ tsp salt: A little seasoning to elevate all the other flavors.
1 tbsp cooking oil: Any neutral-flavored oil works; you can opt for olive oil for a richer taste.
2 oz. feta cheese, crumbled: Provides a tangy creaminess that beautifully contrasts with the other ingredients. Goat cheese can be a delightful substitute.
4 large eggs: The binding agent that holds everything together and gives the quiche its beautiful structure.
¼ cup grated Parmesan cheese: Adds depth with its savory flavor; consider Pecorino Romano for a sharper kick.
¼ tsp freshly cracked black pepper: Elevates the flavor profile and adds a slight kick.
1 cup milk: Keeps the quiche moist and creamy. You can use almond or oat milk for a dairy-free version.
½ cup shredded mozzarella cheese: Melts beautifully on top for that gooey finish.

How to Make Crustless Quiche

Preheat the Oven: Start by preheating your oven to 350ºF, ensuring the perfect environment for baking.
Prepare the Spinach: Thaw the frozen chopped spinach and squeeze out as much moisture as possible. This step is crucial for preventing a soggy quiche.
Sauté the Vegetables: In a skillet, add the sliced mushrooms, minced garlic, salt, and ½ Tbsp cooking oil. Sauté over medium heat until the mushrooms release their moisture and evaporate, leaving you with flavorful sautéed mushrooms.
Prepare the Pie Plate: Brush the remaining ½ Tbsp oil inside a 9-inch pie plate to create a non-stick surface. Layer the sautéed mushrooms, spinach, and crumbled feta cheese in the pie plate.
Mix the Eggs: In a large bowl, whisk together the 4 large eggs, ¼ cup grated Parmesan, freshly cracked black pepper, and 1 cup of milk until well combined.
Combine and Layer: Pour the egg mixture over the layered spinach, mushrooms, and feta in the pie plate. Top with ½ cup of shredded mozzarella cheese, ensuring an even distribution.
Bake: Bake in the preheated oven for about 50 minutes or until the top is golden brown and the internal temperature reaches 160ºF. Enjoy the mouth-watering aroma filling your kitchen as it bakes.

Storing & Reheating

This crustless quiche can be stored at room temperature for up to 2 hours or in the refrigerator for 3-4 days in an airtight container. To freeze, wrap it tightly and store it for up to 3 months. Reheat portions in the microwave for about 1-2 minutes or warm in a 350ºF oven until heated through. While some texture may vary after freezing, a quick time in the oven will refresh its delightful taste.

Chef’s Helpful Tips

Avoid excess moisture: Make sure to thoroughly squeeze the spinach and sauté the mushrooms until they’re dry to prevent a soggy quiche.
Use room temperature eggs: They mix better and create a fluffier texture.
Timing is key: Start checking for doneness around the 45-minute mark. The quiche should be set in the center and golden on top.
Experiment with flavors: Try adding sun-dried tomatoes or different herbs for unique spins.
Make-ahead magic: This quiche is great made ahead and tastes even better the next day!
