FULL RECIPE

Ingredients

• 1 9-inch pre-made or homemade pie crust
• 1 tablespoon butter
• 1 tablespoon olive oil
• 1 small onion, finely chopped
• 8 oz cremini or white mushrooms, sliced
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ¼ teaspoon dried thyme (optional)
• 4 large eggs
• 1 cup half-and-half or whole milk
• 1 cup shredded Swiss cheese
• Optional garnish: chopped fresh parsley or chives

Directions

1. Preheat oven to 375°F (190°C). Place the pie crust into a 9-inch pie plate and crimp the edges. If using a store-bought crust, pre-bake according to package instructions (usually 8–10 minutes).
2. Cook the mushrooms: Heat butter and olive oil in a skillet over medium heat. Add the chopped onion and cook for 2–3 minutes until softened. Add mushrooms, salt, pepper, and thyme. Sauté for 6–8 minutes until mushrooms are tender and the liquid has evaporated. Set aside to cool slightly.
3. Prepare the custard: In a medium mixing bowl, whisk together eggs and half-and-half until smooth. Stir in the shredded Swiss cheese.
4. Assemble the quiche: Evenly spread the mushroom and onion mixture over the bottom of the pre-baked crust. Pour the egg and cheese mixture on top.
5. Bake: Place the quiche in the preheated oven and bake for 35–40 minutes, or until the center is set and a knife inserted near the middle comes out clean. The top should be golden and slightly puffed.
6. Cool and serve: Allow to cool for at least 10 minutes before slicing. Garnish with fresh herbs if desired. Serve warm or at room temperature.

The Comforting Appeal of Mushroom & Swiss Quiche

Mushroom & Swiss Quiche brings together the earthiness of mushrooms and the nutty richness of Swiss cheese in a savory custard encased in a buttery crust. It’s a dish that appeals to both vegetarians and meat-eaters alike thanks to its depth of flavor and satisfying texture. This quiche is ideal for slow weekend brunches, potluck gatherings, or elegant lunches. Its versatility, ease of preparation, and impressive presentation make it a popular go-to for any home cook.

Nutritional Benefits of Mushrooms and Eggs

Mushrooms, the star ingredient in this quiche, offer impressive nutritional benefits. They are low in calories and packed with vitamins, minerals, and antioxidants—particularly selenium, potassium, and B vitamins. Meanwhile, eggs provide a high-quality source of protein, essential amino acids, and healthy fats, along with nutrients like vitamin D, choline, and lutein. Together, these ingredients make the quiche a protein-rich and nutrient-dense meal option, especially when balanced with a whole grain or fresh vegetable side.

Flavor Pairing: Why Mushroom and Swiss Work So Well Together

The pairing of mushrooms and Swiss cheese is a culinary classic. Mushrooms have a savory umami quality that’s enhanced by sautéing, which concentrates their flavor. Swiss cheese, with its nutty and slightly sweet undertones, balances this depth with a creamy, mild sharpness. When melted into a silky egg custard, the two create a harmonious flavor profile that is both comforting and sophisticated. This pairing is ideal for a quiche because it keeps the flavor balanced without overpowering the delicate egg base.

Crust Options and Substitutes

While a buttery, flaky pie crust is traditional for quiche, there are many options for those seeking alternatives. For a gluten-free version, one can use a crust made from almond flour, oat flour, or a pre-made gluten-free pastry. Low-carb or keto-friendly diets may prefer a crust made from crushed nuts or cauliflower. Some cooks also choose to go crustless, baking the quiche directly in a greased dish—this reduces calories and carbs while maintaining the dish’s core appeal. Each crust variation offers a different texture and flavor experience.

Best Cheese Alternatives for Customization

Swiss cheese offers a signature nuttiness, but many other cheeses can be used to suit your taste. Gruyère, a type of Swiss cheese, delivers a stronger flavor and creamier melt, making it a popular upgrade. Fontina, provolone, or white cheddar are excellent alternatives that provide similar richness. For a tangier note, goat cheese or feta can be added in small amounts. Mixing cheeses is also an option, allowing for a more complex and nuanced flavor profile.

Vegetable Add-Ins and Seasonal Variations

This quiche serves as a wonderful canvas for seasonal vegetables and garden harvests. Spinach, leeks, asparagus, bell peppers, and zucchini all pair beautifully with mushrooms and eggs. In the fall, roasted squash or caramelized onions can add a touch of sweetness and depth. The key is to lightly cook any additional vegetables before adding them to the quiche to avoid excess moisture, which can compromise the texture of the custard. With the right balance, you can create endless variations to match any season or occasion.

Serving Suggestions and Presentation Tips

For a well-rounded meal, serve Mushroom & Swiss Quiche with a crisp green salad dressed in a light vinaigrette. A side of roasted potatoes or fresh fruit also complements the dish beautifully, especially for brunch. When serving guests, garnish each slice with fresh herbs like parsley or chives for a vibrant pop of color. Cutting clean slices is easier if the quiche is allowed to rest and cool slightly before serving, which also helps enhance the flavor.

Ideal Drink Pairings

This quiche pairs wonderfully with both hot and cold beverages depending on the time of day. For breakfast or brunch, coffee, black tea, or a glass of fresh-squeezed juice works well. If you’re serving it later in the day, a glass of dry white wine like Chardonnay or Sauvignon Blanc complements the earthy mushrooms and creamy Swiss cheese. Sparkling water with lemon or a crisp apple cider also makes for a refreshing non-alcoholic pairing that balances the richness of the dish.

Storage and Reheating Guidelines

Mushroom & Swiss Quiche stores very well, making it perfect for meal prep or leftovers. Once cooled, cover tightly and refrigerate for up to four days. For longer storage, quiche can be wrapped and frozen for up to two months. When reheating, use a 325°F (160°C) oven until warmed through to help retain the original texture. Avoid microwaving, if possible, as it can make the crust soggy and the custard rubbery. Letting the quiche rest at room temperature for a few minutes after reheating improves the consistency and flavor.

Making Ahead for Entertaining or Busy Mornings

Quiche is a fantastic make-ahead dish. You can fully bake it the day before and simply reheat before serving, or prepare the crust and filling separately and assemble just before baking. For brunch events, this minimizes kitchen stress and allows you to spend more time with guests. The flavors often deepen after a few hours in the fridge, making it even more delicious the next day. Having a ready-made quiche on hand also makes for a quick lunch or satisfying snack during the week.

Conclusion

Mushroom & Swiss Quiche is a rich, savory, and versatile dish that combines gourmet appeal with everyday practicality. Its satisfying flavor and creamy texture make it a standout centerpiece for any brunch table or a comforting, nutrient-rich breakfast or dinner option. With countless ways to adapt the recipe—from crust choices to added vegetables and cheeses—it invites creativity while maintaining its hearty, down-to-earth charm. Whether served hot or cold, alone or with sides, this quiche offers both elegance and ease for any occasion.
