Why Spinach and Mushroom are a Perfect Pairing?

Spinach and mushrooms make an ideal combination for quiche because they balance each other beautifully:

• Spinach is slightly sweet with a fresh, vibrant taste. It also adds a gorgeous pop of green, making the quiche look just as good as it tastes!
• Mushrooms bring a deep, umami-rich flavor that adds complexity to every bite. Plus, their meaty texture makes the quiche feel hearty and filling.
• Together, they create a delicious harmony—a mix of freshness and earthiness wrapped in a creamy, cheesy egg custard.

Fun fact: This quiche is a great way to sneak in some greens without anyone complaining! If you have picky eaters at home, they won’t even notice they’re getting a good dose of veggies.

Step-by-Step Guide to Making Spinach and Mushroom Quiche

Now that we’ve got all our ingredients ready, it’s time to start cooking! This step-by-step guide will help you create a perfectly creamy, flavorful quiche with a flaky crust and a custard that’s just the right consistency. No more soggy bottoms or overcooked eggs—just pure, delicious goodness.

Preparing the Crust: Tips for a Flaky and Buttery Base

A great quiche starts with an excellent crust. Whether you’re using a store-bought crust or making one from scratch, here’s how to get the best results:

1. Pre-bake the crust (blind baking) – This is a must-do if you want to avoid a soggy bottom.
   • Preheat your oven to 375°F (190°C).
   • Roll out the dough and press it into a pie dish.
   • Place parchment paper over the dough and fill it with baking beans or rice.
   • Bake for 10-12 minutes, then remove the weights and bake for another 5 minutes until it looks slightly golden.
2. Let it cool before adding the filling – If you pour in the custard while the crust is hot, it can turn soggy.

Sautéing Mushrooms and Spinach for Maximum Flavor

Cooking the veggies before adding them to the quiche is key. Mushrooms release a lot of moisture, and spinach wilts quickly, so proper sautéing prevents excess liquid from ruining the quiche texture.

1. Heat a pan over medium heat and add 1 tbsp of butter or olive oil.
2. Add the chopped onions and cook for 2 minutes until they soften.
3. Stir in the sliced mushrooms and cook for 5-6 minutes, stirring occasionally, until they release their water and turn golden brown.
4. Add the minced garlic and cook for 30 seconds (just until fragrant).
5. Toss in the chopped spinach and stir until wilted—about 1-2 minutes.
6. Season with salt, pepper, and a pinch of nutmeg for extra depth of flavor.

Once cooked, set aside and let the mixture cool slightly before adding it to the quiche.

Mixing the Perfect Egg Custard

The egg custard is the heart of any quiche. It should be light yet creamy, firm but not dry. Here’s how to get it just right:

1. In a mixing bowl, whisk together:
   • 4 large eggs
   • 1 cup heavy cream
   • ½ cup milk
   • ½ tsp salt
   • ¼ tsp black pepper
   • A pinch of nutmeg (optional, but enhances the richness!)
2. Whisk until smooth, making sure the eggs and cream are fully incorporated.

Pro Tip: For a lighter quiche, use half-and-half instead of heavy cream. Want to try a different take on egg dishes? Check out our Breakfast Potatoes recipe for a hearty, quiche-friendly side dish!

Assembling and Baking: Achieving the Perfect Texture

Now it’s time to bring everything together!

1. Sprinkle half of the shredded cheese over the bottom of the pre-baked crust.
2. Evenly spread the sautéed spinach and mushrooms over the cheese.
3. Pour the egg custard mixture gently over the veggies.
4. Top with the remaining cheese, ensuring an even layer.

Bake at 375°F (190°C) for 35-40 minutes, or until the center is set and the top is lightly golden brown.

How do you know that your Spinach and Mushroom Quiche is done?

• The center should be slightly firm but still have a gentle jiggle.
• If you insert a knife near the center, it should come out mostly clean.

Let it cool for at least 10 minutes before slicing—this helps it set properly and makes for cleaner slices!

Cooling and Serving: Letting the Quiche Set

This step is often overlooked, but it makes a huge difference! When the quiche is fresh out of the oven, it’s still setting up. If you slice it too soon, you’ll lose that creamy texture.

• For best results, let it sit for 10-15 minutes before cutting.
• If serving later, you can reheat slices in the oven at 300°F (150°C) for 10 minutes.

Common Problems and How to Fix Them

Making a quiche might seem straightforward, but small mistakes can lead to a watery filling, soggy crust, or uneven texture. Let’s go over some of the most common problems and how to fix them so that your Spinach and Mushroom Quiche comes out perfect every time.

Why is My Quiche Watery?

If your quiche turns out too runny or watery, the issue likely comes from one of these culprits:

• Underbaked custard – The eggs need time to fully set. If your quiche is still jiggly in the center after baking, give it another 5-10 minutes in the oven.
• Too much liquid from vegetables – Mushrooms and spinach release a lot of moisture when cooked. Always sauté them first to remove excess water before adding them to the quiche.
• Incorrect egg-to-cream ratio – Too much milk or cream and not enough eggs can lead to a custard that never properly sets. Stick to the 4 eggs to 1 ½ cups liquid ratio for the best results.

How to Prevent a Soggy Bottom?

A soggy crust is one of the biggest disappointments in quiche-making. Here’s how to avoid it:

• Pre-bake (blind bake) the crust – This is non-negotiable! Always bake the crust for 10-12 minutes before adding the filling.
• Brush the crust with egg wash – Before adding the filling, brush the pre-baked crust with a beaten egg and bake it for another 2 minutes. This creates a protective layer that prevents the custard from soaking in.
• Use a metal or glass pie dish – These conduct heat better than ceramic, ensuring the crust gets nice and crispy.

Can I Make a Crustless Spinach and Mushroom Quiche?

Absolutely! A crustless quiche is a great option if you’re looking for something gluten-free or just want to cut down on carbs. Here’s what to do:

• Grease the baking dish generously with butter or cooking spray.
• Increase the eggs to 5 – Without the crust, you need one extra egg to help the quiche hold its shape.
• Bake at a slightly lower temperature (350°F/175°C) for about 5-10 minutes longer to prevent burning the edges.

How to Keep the Quiche from Being Too Dense?

A great quiche should be light and creamy, not overly firm or rubbery. If yours turns out too dense, it could be because:

• You overmixed the eggs – Whisk gently to avoid incorporating too much air, which can lead to a tough texture.
• You used too much cheese – While we all love extra cheese, too much can make the filling heavy. Stick to 1 cup for a balanced texture.
• You baked it at too high a temperature – Keep the oven at 375°F (190°C). A high temperature can cause the custard to cook too fast, leading to a firm, dry texture instead of a creamy one.

Variations and Customizations

Want to put your own spin on Spinach and Mushroom Quiche? Here are some fun ways to switch things up!

Adding Protein: Chicken, Bacon, or Tofu Options

• Chicken – Dice up some grilled or roasted chicken and mix it with the mushrooms for extra heartiness.
• Bacon – A classic addition! Cooked, crispy bacon crumbles add a savory, smoky touch.
• Tofu – For a vegetarian protein boost, crumble firm tofu and season it with garlic, paprika, and black pepper before mixing it into the filling.

Making it Dairy-Free: Vegan Spinach and Mushroom Quiche

Yes, you can make a completely dairy-free quiche! Here’s how:

• Use full-fat coconut milk or almond milk instead of heavy cream.
• Replace eggs with a flaxseed mixture (1 tbsp flaxseed + 2.5 tbsp water per egg).

• Hash brown crust – Use shredded potatoes pressed into the pan as a crust alternative.
