Recommendations for Freshness
To ensure your quiche is fresh and tasty:
- Buy spinach and mushrooms that are bright and firm, not wilted or slimy.
- Use eggs that are as fresh as possible; check the sell-by date.
- Store your heavy cream in the fridge and check for any sour smell before use.
- If you have leftovers, keep them in the fridge in an airtight container for up to three days.

Step-by-Step Instructions
Prepping the Ingredients
First, gather your ingredients. You need:
- 1 pre-made pie crust
- 2 cups fresh spinach, finely chopped
- 1 cup mushrooms, sliced
- 4 large eggs
- 1 cup heavy cream
- 1 cup shredded cheese
- 1 medium onion, diced
- 2 cloves garlic, minced
- 1 teaspoon dried thyme
- Salt and black pepper
- 2 tablespoons olive oil
To start, rinse the spinach under cold water. Chop it finely. Next, slice the mushrooms. Use both button and cremini for great flavor. Dice the onion and mince the garlic. This prep makes cooking easy.
Cooking the Filling
Heat the olive oil in a large skillet over medium heat. Add the diced onion and cook it for about 3-4 minutes. Stir until it’s soft and clear. Then, add the minced garlic and cook for one more minute. The smell will be amazing!
Now, add the sliced mushrooms. Cook them for about 5-7 minutes. They should turn brown and release their moisture. Once the mushrooms are ready, stir in the chopped spinach and dried thyme. Cook until the spinach wilts down. Season with salt and pepper to taste. Remove from heat and let it cool slightly.
Assembling and Baking the Quiche
In a mixing bowl, whisk the eggs and heavy cream together. Make sure they blend well. Add salt and pepper to taste. Now, gently fold the cooled spinach and mushroom mix into the egg mixture. Be careful not to break the veggies.
Place your pie crust in a quiche or pie dish. Pour the filling into the crust, spreading it evenly. Top it off with shredded cheese.
Now, it's time to bake! Preheat your oven to 375°F (190°C). Bake the quiche for 35-40 minutes. It’s done when the center is set and the top is golden brown.
Let the quiche cool for about 10 minutes before slicing. Enjoy your delicious spinach mushroom quiche!
Tips & Tricks
Avoiding a Soggy Crust
To prevent a soggy crust, you need to bake it a bit before adding the filling. This step is called blind baking. To do this, line your pie crust with parchment paper and fill it with pie weights or dry beans. Bake it for about 10 minutes at 375°F (190°C). This helps the bottom cook well and stay crisp. After blind baking, let the crust cool slightly before adding the filling.
Perfecting the Egg Mixture
The egg mixture is key to a tasty quiche. Use fresh eggs for the best flavor. Beat the eggs well with the heavy cream. This mix should be smooth and creamy. You can use half-and-half if you want a lighter option. Don't forget to season it! Salt and pepper enhance the taste. You can also add herbs or spices to match your style.
Serving Suggestions for Spinach Mushroom Quiche
This quiche is great on its own, but you can jazz it up. Serve it with a side salad for a fresh crunch. A simple green salad with lemon dressing works well. You can also serve it with roasted vegetables for a heartier meal. For added flair, top each slice with fresh herbs like parsley or chives. This adds flavor and makes your dish look beautiful.
Pro Tips
- Use Fresh Ingredients: Always opt for fresh spinach and mushrooms for the best flavor and texture in your quiche.
- Experiment with Cheese: Try different cheese combinations like feta or goat cheese for a unique twist on the traditional quiche.
- Chill the Crust: Before baking, chill your pie crust in the refrigerator for 15 minutes to prevent it from shrinking during baking.
- Let it Rest: Allow the quiche to rest for at least 10 minutes after baking to help it set and make slicing easier.

Variations
Adding Protein (e.g., bacon or ham)
You can add protein to your quiche for extra flavor. Bacon or ham works great. Cook the bacon until crispy, then crumble it into the filling. If you prefer ham, chop it into small pieces and stir it in. This adds a savory touch that pairs well with spinach and mushrooms.
Dairy-Free Alternatives
If you want a dairy-free quiche, you have options. Use plant-based milk like almond or oat milk instead of cream. For the cheese, try vegan cheese or nutritional yeast for a cheesy taste. This way, you can enjoy the quiche while keeping it dairy-free.
Customizing Vegetables
Feel free to mix up the veggies. You can add bell peppers, zucchini, or even broccoli. Just make sure to sauté them first to bring out their flavors. This customization lets you use what you have on hand and makes each quiche unique.
