Ingredients

1 sheet of store-bought or homemade pie crust (enough to cover a 12×18-inch pan)
8 large eggs
2 cups heavy cream or whole milk
1 teaspoon salt
1/2 teaspoon black pepper
1/4 teaspoon ground nutmeg (optional)
1 1/2 cups shredded cheese (cheddar, Gruyère, or Swiss work well)

1 cup cooked bacon or ham, chopped (optional)
1 cup fresh spinach, chopped or wilted (optional)
1/2 cup diced onions or leeks (optional)
1 cup cherry tomatoes, halved (for topping, optional)

Instructions

Preheat your oven to 375°F (190°C). Lightly grease a 12×18-inch baking dish or line it with the pie crust, pressing it into the corners and up the sides.
Prepare the crust. If using a homemade crust, roll it out to fit the pan. If using store-bought, gently fit it into the dish, trimming any excess edges.
Blind bake the crust. Prick the bottom with a fork a few times, then line it with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, then remove the weights and parchment.

Cook any fillings. If using vegetables like spinach or onions, sauté until tender. Cook bacon or ham if not pre-cooked. Let any cooked ingredients cool slightly.
Mix the filling. In a large bowl, whisk together eggs, cream, salt, pepper, and nutmeg. Stir in cheese, cooked meats, vegetables, and herbs.
Pour the filling into the crust. Spread evenly, ensuring ingredients are distributed throughout.

Add toppings. If desired, sprinkle cherry tomatoes or extra cheese on top for visual appeal and added flavor.
Bake the quiche. Place in the oven and bake for 40-45 minutes, or until the filling is set and the top is golden brown.
Cool before serving. Let the quiche rest for about 10 minutes before slicing to allow the filling to firm up, making it easier to cut clean slices.

Tips

Substitutions: You can swap the cheese for different varieties like feta or mozzarella, and use milk instead of cream for a lighter version.
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat slices in the oven at 350°F (175°C) for about 10 minutes or until warmed through.
Prevent sogginess: Blind baking the crust helps prevent it from becoming soggy once filled. Avoid overfilling the quiche, which can cause spillage or uneven cooking.

Uniform slices: Use a sharp knife and wipe it clean between cuts for neat, professional-looking slices.

Serving Suggestions

Serve the quiche warm or at room temperature alongside a fresh green salad, some crusty bread, or fruit for a well-rounded meal. It pairs beautifully with a light white wine or sparkling water with lemon for brunch gatherings.

Variations

Customize your quiche with different fillings: add sautéed mushrooms, roasted peppers, or smoked salmon for a gourmet touch. You can also make a vegetarian version by increasing the vegetable content and skipping the meats. For a gluten-free option, use a gluten-free pie crust or make a crustless quiche.

Storage and Reheating

Refrigerate leftover quiche in an airtight container for up to 3 days. To reheat, place a slice on a baking sheet and warm in a preheated oven at 350°F (175°C) for 10-15 minutes until heated through. You can also microwave individual slices for about 1-2 minutes, though the crust may lose some crispness. For best results, reheat in the oven to preserve texture.

Frequently Asked Questions

Can I make this quiche ahead of time?

Yes, you can prepare the quiche a day in advance. Assemble and bake it as directed, then let it cool completely before storing in the refrigerator. Reheat in the oven at 350°F (175°C) for about 15 minutes before serving to refresh the crust and filling.

How do I know when the quiche is done?

The quiche is ready when the filling is set and no longer jiggles in the center. The top should be golden brown. You can insert a toothpick or a knife into the center—if it comes out clean, the quiche is baked through.

Can I freeze leftovers?

Absolutely. Wrap individual slices tightly in plastic wrap or foil, then place in a freezer-safe container. They can be frozen for up to 2 months. To reheat, thaw overnight in the refrigerator and warm in the oven or microwave.

Is a crust necessary for this recipe?

No, you can make a crustless quiche by simply pouring the filling into a greased baking dish. It’s a lighter option and cooks slightly faster. Adjust baking time to about 35-40 minutes.

What are some good fillings for a 12×18 quiche?

Popular fillings include cheese varieties like Swiss, cheddar, or Gruyère, cooked meats such as bacon, ham, or sausage, and vegetables like spinach, mushrooms, bell peppers, and onions. Feel free to mix and match based on your preferences.

Can I make this recipe gluten-free?

Yes, substitute the pie crust with a gluten-free crust or make a crustless quiche. Ensure all ingredients, especially processed items like bacon or cheese, are gluten-free if needed.

This 12×18 quiche recipe offers a perfect balance of flavor, size, and versatility, making it an excellent choice for any meal or gathering. Experiment with fillings and toppings to create your signature version, and enjoy a delicious, satisfying dish that’s easy to prepare and serve.
