When I first created this quiche, I was inspired by my love for savory breakfasts. The delightful combination of fresh spinach, earthy mushrooms, and a creamy egg filling makes this recipe a standout. I experimented with different herbs and spices, ultimately finding that a hint of nutmeg elevates the flavors beautifully.

To get the best results, be sure to sauté the mushrooms properly before adding them to the mix. This step helps draw out their moisture, ensuring the quiche doesn't turn out soggy. I’ve served it to guests multiple times, and it always receives rave reviews!

Perfecting the Crust

A flaky pie crust is key to a successful quiche. If using a pre-made crust, ensure it is fully thawed if frozen and gently fit it into the pie dish without stretching. If you prefer homemade, chill your butter before incorporating it into the flour to achieve that short crust texture. After placing the crust in the dish, I recommend blind-baking it for 10 minutes at 375°F (190°C) to prevent sogginess from the filling.

When blind baking, use pie weights or dried beans to help maintain the shape of the crust. This step helps to set the crust before adding your rich filling, leading to a more stable texture that won't collapse under the weight of the quiche. Keep an eye out for golden edges, indicating that it's ready.

Choosing Vegetables Wisely

While spinach and mushrooms are wonderful in this quiche, feel free to customize the filling based on seasonal produce. Zucchini, bell peppers, or even kale can work beautifully, each bringing a unique flavor and texture. If you opt for watery vegetables like zucchini, consider sautéing them longer to evaporate excess moisture before adding to the egg mixture.

Also, consider using frozen vegetables as an alternative, but ensure they are fully thawed and drained before incorporating them. This prevents dilution of the quiche's flavor and maintains the proper texture. The sautéing step for your vegetables is crucial, not just for flavor but for achieving that glossy, well-blended mixture that enhances the entire quiche.

Ingredients

For the Quiche

1 pre-made pie crust
6 large eggs
1 cup milk
2 cups fresh spinach, chopped
1 cup mushrooms, sliced
1 cup shredded cheese (cheddar or your preference)
1/2 onion, finely chopped
1 teaspoon garlic powder
1/2 teaspoon nutmeg
Salt and pepper to taste

Instructions

Preparation Steps

Preheat the Oven

Preheat your oven to 375°F (190°C).

Prepare the Filling

In a skillet, sauté the chopped onions and sliced mushrooms over medium heat until the mushrooms release their moisture and become tender, about 5-7 minutes. Add the chopped spinach and stir until wilted.

Make the Egg Mixture

In a large bowl, whisk together the eggs, milk, garlic powder, nutmeg, salt, and pepper. Stir in the sautéed vegetables and cheese.

Assemble the Quiche

Fit the pie crust into a pie dish and pour the egg and vegetable mixture into the crust.

Bake

Bake in the preheated oven for 30-35 minutes, or until the quiche is set and the top is lightly golden.

Cool and Serve

Allow the quiche to cool for a few minutes before slicing and serving. Enjoy warm or at room temperature.

Enjoy Your Quiche!

Pro Tips

Experiment with different vegetables and cheeses according to your taste. This quiche is also excellent with some herbs like parsley or thyme for added flavor!

Storing and Reheating

This quiche makes for excellent leftovers! Store any uneaten portions in an airtight container in the refrigerator for up to three days. For optimal flavor and texture, reheat slices in a preheated oven at 350°F (175°C) for about 10-15 minutes until warm. Reheating on a baking sheet ensures a crispy crust rather than a soggy one, maintaining that flaky texture you love.

If you want to make this quiche further in advance, you can freeze it either before baking or after it cools completely. Wrap it tightly in plastic wrap and then foil, ensuring that no air can enter. To reheat from frozen, thaw overnight in the fridge and then bake at the same temperature until heated through.

Serving Suggestions

This quiche pairs wonderfully with a light side salad or some fresh fruit, creating a balanced brunch option. I enjoy serving it alongside a simple arugula salad dressed with lemon vinaigrette; the peppery arugula complements the creamy quiche nicely. You can also add a dollop of sour cream or a sprinkle of fresh herbs like chives or parsley for added flavor and presentation.

For a fun twist, consider serving mini versions at gatherings by using a muffin tin instead of one large dish. This allows for individual portions that are perfect for brunch parties or potlucks. Just be sure to adjust the baking time, checking for a golden top and firm center at around 20-25 minutes.
