Ingredients You’ll Need

Gathering simple, fresh ingredients is key to making any dish truly shine, and this quiche is no exception. Each component plays a vital role in balancing taste, texture, and visual appeal, coming together effortlessly for a dish that feels both homey and elegant.

• 6 large eggs: The foundation of your quiche, providing that wonderful custard texture and protein-packed goodness.
• 1 cup milk (or half-and-half): Adds creaminess—use half-and-half if you want it richer and more indulgent.
• 150 g fresh spinach, chopped: Brings a fresh, vibrant green color and a mild, slightly earthy flavor.
• 150 g mushrooms, sliced: Offers a wonderful umami depth and meaty texture that complements the softness of the spinach.
• 100 g feta cheese, crumbled: Introduces tangy saltiness and creamy bursts in every bite.
• 1 small onion, finely chopped: Adds a sweet, aromatic base when sautéed.
• 1 tbsp olive oil: Used for sautéing vegetables, it enriches the flavors with its fruity notes.
• Salt and black pepper, to taste: Essential seasoning to bring all the flavors together harmoniously.
• ¼ tsp nutmeg (optional): A warm, subtle spice that elevates the custard’s flavor beautifully when added thoughtfully.

How to Make Classic Spinach & Feta Crustless Mushroom Quiche

Step 1: Prepare Your Oven and Dish

Start by preheating your oven to 180°C (350°F). While it warms up, grease a 9-inch pie dish or any similar baking dish generously—this ensures your quiche releases easily once baked, keeping every slice pristine and intact.

Step 2: Sauté the Vegetables

Heat the olive oil in a skillet over medium heat. Add the finely chopped onion and cook gently until it becomes translucent and sweet. Next, stir in the sliced mushrooms and cook until they soften and release their earthy aroma. Finally, add the chopped spinach, letting it wilt naturally. Once the veggies are tender and fragrant, remove the skillet from heat and allow the mixture to cool slightly—this keeps your eggs from scrambling in the next step and enhances the texture of the quiche.

Step 3: Whisk the Custard

In a large mixing bowl, whisk together the eggs, milk (or half-and-half for that richer touch), salt, pepper, and if you’re using it, the nutmeg. Take a moment here to really whisk until the mixture is smooth and slightly frothy; this will make a wonderfully light and creamy custard base for the quiche.

Step 4: Combine and Fill

Gently stir your sautéed vegetables into the egg mixture, then carefully fold in the crumbled feta cheese. This combination balances softness with bursts of salty tang. Pour the entire mixture evenly into your prepared baking dish, spreading it for an even cook and beautiful golden top.

Step 5: Bake to Perfection

Place your quiche in the oven and bake for 35 to 40 minutes. You’ll know it’s ready when the custard sets firmly and the top gleams with a golden hue. Avoid opening the oven door too often during baking to keep your quiche beautifully puffed and perfectly cooked.

Step 6: Cool and Serve

Once out of the oven, let your quiche cool for about 5 to 10 minutes in the pan. This resting time helps it firm up slightly, allowing you to cut clean slices that hold their shape. Serve it warm or at room temperature to enjoy the full range of flavors.

How to Serve Classic Spinach & Feta Crustless Mushroom Quiche

Garnishes

A sprinkle of freshly chopped parsley or a handful of microgreens can add a fresh burst of color and a subtle herbaceous flavor to your quiche. A light dusting of cracked black pepper or a drizzle of high-quality olive oil also elevates the dish with just a touch more flavor complexity.

Side Dishes

This crustless quiche pairs wonderfully with crisp, refreshing salads—think a lemony arugula salad or a crunchy cucumber and tomato side. Roasted baby potatoes or warm crusty bread with a dab of butter also complement the richness of the quiche beautifully, making the meal both balanced and satisfying.

Creative Ways to Present

For a lovely brunch spread, slice the quiche into small squares and arrange them on a wooden board alongside bowls of olives, fresh fruit, and artisan cheeses. You can also prepare individual mini quiches using ramekins for an elegant, personalized touch that dazzles guests.

Make Ahead and Storage

Storing Leftovers

Leftover Classic Spinach & Feta Crustless Mushroom Quiche keeps well in the refrigerator for up to 3 days when stored in an airtight container. Its flavors tend to deepen overnight, making it just as delicious, if not more so, the next day.

Freezing

If you want to keep this quiche longer, it freezes wonderfully. Slice it into portions and wrap each tightly in plastic wrap before placing in a freezer bag. It will keep well for up to 2 months. Just make sure to thaw thoroughly in the fridge before reheating.

Reheating

To reheat, place slices on a baking tray in a preheated oven at 160°C (320°F) until warmed through—about 10 to 15 minutes. Avoid microwaving when possible to maintain the quiche’s lovely texture, but if you do, cover the quiche to retain moisture and heat gently.

FAQs

Can I use frozen spinach instead of fresh in the quiche?

Absolutely! Just be sure to thaw and squeeze out as much excess water as possible to avoid a soggy quiche. Frozen spinach is a handy pantry staple that works well here.

Is half-and-half necessary for creaminess?

Nope, milk works perfectly fine and makes the dish lighter. However, if you prefer a richer, silkier texture, substituting with half-and-half is a delicious upgrade.

Can I add other vegetables to this quiche?

Definitely. Bell peppers, zucchini, or even sun-dried tomatoes can be excellent additions. Just sauté them with the onion and mushrooms to soften before mixing in.

How do I know when the quiche is fully cooked?

The top should be golden and the center set but slightly wobbly when you gently shake the pan. If it jiggles too much, give it a bit more time in the oven.

Is this quiche suitable for meal prep?

Yes, it is fantastic for meal prep! Make it ahead, slice, and portion out for easy breakfasts, lunches, or dinners. It tastes great warm or cold depending on your preference.
