Crustless Quiche with Leeks, Mushrooms, and Fontina Cheese

What is a Crustless Quiche?

  • A custard baked with simple ingredients in a pie dish, without the need for a crust.
  • Great for transforming fresh veggies into a delicious, satisfying meal.

Versatility:

  • Can be made vegetarian or with added protein like ham or bacon.
  • Naturally gluten-free, making it a perfect option for various dietary needs.
  • Use any vegetables you have on hand—great for both summer and winter produce.

Key Ingredients in This Recipe:

  • Leeks: Lightly caramelized for subtle sweetness.
  • Mushrooms: Cooked just enough to retain their texture, avoiding a soggy result.
  • Fontina Cheese: A creamy, melt-in-your-mouth cheese that adds velvety richness to the custard.
  • Thyme: A herb that pairs beautifully with leeks and mushrooms, enhancing the flavors.
  • Black Pepper: A generous amount to accentuate the vegetables’ natural taste.

No Crust Needed:

  • Vegetables are spread directly in the bottom of the pie dish, eliminating the need for a crust.
  • This makes the dish lighter and easier to prepare.

Special Touches:

  • Decorative topping of sliced mushrooms and shaved leeks for added flavor and visual appeal.
  • The result is a stunning, delicious, and gluten-free quiche perfect for breakfast, brunch, or any occasion.

Tips for Perfecting Your Crustless Quiche

Eggs to Milk Ratio

Ever made a crustless quiche that turned out rubbery? The key to a smooth, creamy quiche is getting the eggs-to-milk ratio right. A quiche is essentially a custard made with milk and eggs, so it’s crucial to balance these ingredients properly for the custard to set.

Rule of Thumb:

  • 1 large egg = ½ cup dairy (milk or cream).
  • For a standard 9-inch quiche, use 3 large eggs and 1 ½ cups of milk.

Length of Baking Time

  • Baking time is critical for a perfect quiche. Overbake it, and you’ll get tiny holes and weeping water. Underbake it, and the filling will be runny.

Perfect Bake:

  • Look for a slight wobble in the center when you take it out of the oven—it should be set but not overly firm.
  • Baking Time: 30-40 minutes at 350°F (175°C).
  • Place your quiche on the bottom rack to prevent the top from cooking too quickly and becoming overdone.

Should You Precook the Filling for a Quiche?

The answer depends on the type of veggies you’re using.

  • Cheese: Use 1-2 cups of cheese for a 9-inch quiche.
  • Heartier Vegetables (e.g., winter squash, carrots, potatoes): These should be cooked or steamed first to reduce moisture and ensure they don’t release excess water into the quiche.
  • Quick-Cooking Vegetables (e.g., spinach, tomatoes, zucchini, asparagus): These can go in fresh, as they cook quickly and release minimal moisture.

By following these simple tips, you’ll ensure your crustless quiche comes out with a smooth, creamy texture and perfectly set filling every time!

Serving and Leftovers

A crustless quiche is incredibly versatile. You can make it rich and indulgent with extra cheese and filling, or opt for a lighter version with less cheese and fewer fillings—perfect for any dietary preference.

Serving Options:

Quiche can be served cold, at room temperature, or warmed. It’s a flexible dish that works well for brunch or as a meal throughout the day.

Reheating Tips:

To reheat, place your quiche in a preheated oven at 300 F (150 C) until it’s just warm to the touch. This will keep the texture smooth without overcooking the custard.

Leftovers:

Store cooled quiche in the refrigerator wrapped in plastic wrap for up to 5 days.
