Best Spinach and Mushroom Crustless Quiche Recipe

Introduction

This Best Spinach and Mushroom Crustless Quiche is a flavorful, lighter alternative to traditional quiche that still delivers creamy, cheesy satisfaction. With layers of sautéed mushrooms, spinach, and feta, it makes a perfect breakfast, brunch, or light dinner option.

Ingredients

• 2 oz feta cheese (crumbled)
• 1/8 tsp salt
• 1 garlic clove (minced)
• 1 tbsp cooking oil (or olive oil)
• 10 oz frozen chopped spinach (thawed and squeezed dry)
• 8 oz mushrooms (sliced into 1/4-inch pieces)
• 1 cup milk (2% recommended)
• 1/2 cup shredded mozzarella
• 1/4 tsp black pepper
• 1/4 cup grated Parmesan (freshly grated preferred)
• 4 large eggs (room temperature)

Instructions

1. Step 1: Preheat your oven to 350°F. Squeeze the thawed spinach firmly in a clean kitchen towel or cheesecloth until completely dry to prevent a watery quiche. Mince the garlic and slice the mushrooms into 1/4-inch pieces.
2. Step 2: Heat 1/2 tablespoon of oil in a skillet over medium-high heat. Add the mushrooms and cook for 4-5 minutes, stirring occasionally, until their moisture evaporates. Add the minced garlic and salt in the last minute, stirring until fragrant. Transfer to a plate.
3. Step 3: Lightly oil a 9-inch pie plate with the remaining 1/2 tablespoon of oil. Spread the mushroom mixture evenly on the bottom, then layer with the squeezed spinach, and crumble feta cheese over the top.
4. Step 4: In a medium bowl, whisk together the room-temperature eggs, milk, Parmesan, and black pepper until smooth and combined.
5. Step 5: Pour the egg mixture over the layered vegetables and cheese. Sprinkle shredded mozzarella evenly on top.
6. Step 6: Bake on the center rack for 50 minutes, or until the center reaches 160°F. The quiche should be set with a slightly soft center.
7. Step 7: Remove from oven and let rest for 5-10 minutes before slicing. Serve warm or at room temperature.

Tips & Variations

• For extra flavor, try adding a pinch of nutmeg or fresh herbs like thyme or chives to the egg mixture.
• Use fresh spinach instead of frozen if preferred—just sauté it first and squeeze out excess moisture.
• Substitute goat cheese or ricotta for feta to vary the cheese profile.
• Ensure the spinach is very dry before layering to avoid a soggy quiche.

Storage

Store leftover quiche covered in the refrigerator for up to 3 days. Reheat individual slices in the microwave or oven until warmed through. The quiche can also be frozen wrapped tightly in foil or plastic wrap for up to 1 month; thaw overnight in the refrigerator before reheating.

Vegetables and Cheese

• 10 oz frozen chopped spinach (thawed and squeezed dry)
• 8 oz mushrooms (sliced into 1/4-inch pieces)
• 2 oz feta cheese (crumbled)
• 1/2 cup shredded mozzarella
• 1/4 cup grated Parmesan (freshly grated preferred)
• 1 garlic clove (minced)

Wet Ingredients & Seasonings

• 4 large eggs (room temperature for better mixing)
• 1 cup milk (2% recommended for best texture)
• 1 tbsp cooking oil (or olive oil), divided
• 1/8 tsp salt
• 1/4 tsp black pepper

Instructions

1. Preheat and Prepare Ingredients: Preheat your oven to 350°F. While the oven is heating, squeeze the thawed spinach firmly in a clean kitchen towel or cheesecloth until completely dry to prevent a watery quiche. Mince the garlic and slice the mushrooms into 1/4-inch pieces.
2. Sauté Mushrooms and Garlic: Heat 1/2 tablespoon of oil in a skillet over medium-high heat. Add the sliced mushrooms and cook for 4-5 minutes, stirring occasionally until the mushrooms release their moisture and the liquid evaporates. Add the minced garlic and salt in the last minute, stirring constantly until fragrant. Transfer the mixture to a plate.
3. Prepare the Pie Plate: Lightly brush the remaining 1/2 tablespoon of oil around the bottom and sides of a 9-inch pie plate. Layer the sautéed mushroom mixture on the bottom, then spread the squeezed spinach evenly on top, and crumble the feta cheese over the spinach layer. This layering balances flavors throughout the quiche.
4. Mix Egg Custard: In a medium bowl, whisk together the room-temperature eggs, milk, grated Parmesan, and black pepper until well combined and smooth. Avoid overmixing to keep the custard cohesive.
5. Assemble the Quiche: Pour the egg mixture evenly over the layered vegetables and cheese in the pie plate. Sprinkle the shredded mozzarella evenly on top to create a golden crust while baking.
6. Bake: Place the pie plate on the center oven rack and bake for 50 minutes, or until the internal temperature reaches 160°F when checked with an instant-read thermometer. The quiche should be set with a slightly soft center that firms up after cooling.
7. Rest and Serve: Remove the quiche from the oven and let it rest at room temperature for 5-10 minutes to allow the custard to set fully. Slice into wedges and serve warm or at room temperature.

Notes

• Ensure the spinach is squeezed thoroughly to avoid excess water making the quiche soggy.
• Use room-temperature eggs for a smoother custard texture.
• Freshly grated Parmesan enhances flavor compared to pre-grated.
• Check quiche doneness using an instant-read thermometer for best results.
• Letting the quiche rest before slicing helps with cleaner presentation.
