Crustless quiche is a wonderful dish that’s both versatile and easy to make. You can customize it with your favorite ingredients, making it suitable for breakfast, lunch, or dinner.

how to make Crustless Quiche

Ingredients:

6 large eggs
⅔ cup whole milk
¼ cup half-and-half
½ teaspoon kosher salt
¼ teaspoon ground black pepper
1 teaspoon Dijon mustard (optional)
Pinch ground nutmeg (optional)
1 ½ cups mix-ins of choice (e.g., ⅔ cup grated Gruyère cheese, 2 tablespoons chopped fresh chives, cooked crumbled lean beef, chopped and sautéed broccoli, caramelized onions, cubed leftover roast beef, roasted vegetables)

Directions:

Preheat Oven & Prepare Dish
Preheat oven to 375°F (190°C). Generously grease a 9-inch pie dish or a similar-sized oven-safe baking dish with butter or cooking spray, ensuring all surfaces are coated to prevent sticking.
Prepare & Sauté Vegetables/Fillings
Prepare your chosen vegetables: thoroughly thaw and squeeze dry any frozen spinach; finely dice onions; slice mushrooms. Heat 1 tablespoon butter or olive oil in a medium skillet over medium heat. Sauté onions for 3-5 minutes until translucent, then add mushrooms and other hardier vegetables (like bell peppers or broccoli) and cook for 5-7 minutes until softened and moisture is released. If using, prepare cooked crumbled lean beef or cubed leftover roast beef. Set all cooked fillings aside to cool slightly.
Whisk Eggs & Dairy Base
In a large mixing bowl, vigorously whisk the 6 large eggs until yolks and whites are fully combined and slightly frothy (about 1-2 minutes). Pour in the ⅔ cup whole milk and ¼ cup half-and-half. Add ½ teaspoon kosher salt, ¼ teaspoon ground black pepper, 1 teaspoon Dijon mustard (if using), and a pinch of ground nutmeg (if using). Whisk all ingredients thoroughly until well incorporated, forming a homogenous base.
Combine Fillings
Add your 1 ½ cups of mix-ins, including the ⅔ cup grated Gruyère cheese, 2 tablespoons chopped fresh chives, and your cooled sautéed vegetables/prepared lean beef/roast beef, directly into the egg and dairy mixture. Gently fold with a spatula until all fillings are evenly distributed throughout the egg base, avoiding overmixing.
Bake the Quiche
Carefully pour the entire quiche mixture into your generously greased 9-inch pie dish. Place the dish into the preheated 375°F (190°C) oven and bake for 40 to 55 minutes. The quiche is done when the top is golden brown and the center is set, showing only a slight, uniform jiggle when gently moved. If the top browns too quickly, loosely tent with aluminum foil for the last 10-15 minutes of baking.
Cool & Serve
Once baked, carefully remove the quiche from the oven. Allow it to cool on a wire rack for at least 10-15 minutes (up to 20 minutes) before slicing. This crucial cooling period allows the custardy filling to fully set, ensuring clean and beautiful slices. Serve warm, either on its own or with a fresh green salad for a complete meal.

To store leftovers, allow the quiche to cool completely. Then, cover it tightly with plastic wrap or aluminum foil and refrigerate for up to 3-4 days.
