1 clove garlic, minced – A dash of garlic brings a punch of flavor that elevates the quiche to new heights.
1/8 tsp salt – A pinch is crucial for enhancing the overall taste of your ingredients.
1 Tbsp cooking oil (divided) – We’ll use this to sauté and to give our pie plate a little TLC, ensuring nothing sticks!
2 oz. feta cheese – This salty, creamy cheese is the star of the show, lending richness that complements the spinach perfectly.
4 large eggs – The base of our quiche, eggs help hold everything together while adding protein.
1/4 cup grated Parmesan – A sprinkle of Parmesan brings a nutty flavor and crispy texture on top; who doesn’t love some cheese?
1/4 tsp pepper – A hint of pepper provides just the right amount of warmth to elevate the dish.
1 cup milk – We’ll blend this into our egg mixture to create a light, luscious filling.
1/2 cup shredded mozzarella – The cherry on top! Melty mozzarella adds a gooey, delightful finish to our quiche.
How to Make Spinach & Mushroom Quiche
Follow these simple steps to prepare this delicious Spinach & Mushroom Quiche:
Step 1: Preheat the Oven
Preheat your oven to 350°F. While the oven heats up, grab that box of frozen spinach, thaw it, and squeeze out as much moisture as you can. No one wants a soggy quiche!
Step 2: Prepare the Vegetables
Rinse the mushrooms, then slice them thinly. Mince the garlic to release its aromatic goodness – this will be the flavor base that makes everything pop.
Step 3: Sauté the Mushrooms
In a skillet, add the sliced mushrooms, minced garlic, salt, and ½ tablespoon of cooking oil. Sauté over medium heat, stirring occasionally, until all the moisture has evaporated and the mushrooms are nicely browned—this should take about 8 minutes.
Step 4: Assemble the Quiche Base
With the remaining ½ tablespoon of cooking oil, brush it inside a 9-inch pie plate. Layer the sautéed mushrooms, thawed spinach, and crumbled feta cheese inside the plate evenly.
Step 5: Make the Egg Mixture
In a large bowl, whisk together the eggs, grated Parmesan, pepper, and milk until they are fully combined and frothy. Pour this delightful mixture over the spinach, mushrooms, and feta to bind everything together.
Step 6: Top and Bake
Sprinkle the shredded mozzarella atop the quiche for that beautiful, melty finish. Slide the pie plate into the preheated oven and let it bake for about 50 minutes. It should turn golden brown, with a gentle jiggle in the middle when you shake it slightly.
Once the internal temperature reaches 160°F and the quiche is perfectly baked, slice it while it’s still warm. Serve each piece with a sprinkle of fresh herbs for an extra touch of class and flavor on your plate.
There you have it—a simple, yet impressive Spinach & Mushroom Quiche ready to make any occasion shine. Whether you serve it warm right out of the oven or at room temperature, this delightful dish is sure to win hearts and leave everyone looking for seconds. Bon appétit!
