Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 45-50 minutes
• Total Time: 1 hour 5 minutes – 1 hour 10 minutes
• Servings: 6
• Yield: 1 quiche
• Dietary Type: Vegetarian

Ingredients

• 1 onion, thinly sliced
• 2 cups broccoli florets
• 1 red pepper, seeded and cut into cubes
• 4 whole eggs
• 2 egg whites (or substitute an additional whole egg)
• ¾ cup milk
• ¾ cup evaporated milk
• ¼ teaspoon salt
• ¼ teaspoon pepper
• ¼ teaspoon nutmeg
• 1 teaspoon Dijon mustard
• ½ cup shredded Gruyere cheese
• ¼ cup green onion, chopped
• 1 tablespoon grated Parmesan cheese
• 1 teaspoon margarine, melted

Equipment Needed

• Baking sheet
• Parchment paper
• Whisk
• 10-inch quiche dish
• Oven

Instructions

1. Begin by preheating your oven to 400°F (200°C).

2. Prepare the vegetables for roasting: Evenly spread the thinly sliced onion, broccoli florets, and cubed red pepper on a baking sheet lined with parchment paper. This prevents sticking and ensures even browning.

3. Roast the vegetables at 400°F for 15 minutes, being sure to turn them halfway through the cooking time to ensure they’re evenly cooked and slightly caramelized. This roasting step brings out the natural sweetness of the vegetables, adding depth of flavor to the quiche.

4. While the vegetables are roasting, prepare the egg mixture. In a mixing bowl, whisk together the 2 egg whites and 4 whole eggs until light and frothy. This ensures a smooth and even texture in the baked quiche.

5. Add the milk, evaporated milk, salt, pepper, ground nutmeg, and Dijon mustard to the egg mixture. Whisk until all ingredients are well combined. The nutmeg adds a subtle warmth, while the Dijon mustard provides a tangy counterpoint to the richness of the cheese.

6. Brush a 10-inch quiche dish with the melted margarine. This will prevent the quiche from sticking to the dish. Be sure to coat the bottom and sides of the dish evenly.

7. Assemble the quiche. Place the roasted vegetables in the prepared quiche dish, distributing them evenly across the bottom.

8. Sprinkle the shredded Gruyere cheese and chopped green onions over the roasted vegetables. The Gruyere will melt beautifully, creating a gooey and flavorful layer.

9. Gently pour the egg mixture over the vegetables and cheese, ensuring it’s evenly distributed.

10. Sprinkle the grated Parmesan cheese over the top of the quiche. This will create a golden-brown crust as it bakes.

11. Bake the quiche at 375°F (190°C) for 30-35 minutes, or until a knife inserted near the center comes out clean. A slight jiggle is okay, as the quiche will continue to set as it cools.

12. Once the quiche is done, remove it from the oven and let it cool for at least 10 minutes before slicing and serving. This allows the filling to set properly, making it easier to slice.

Expert Tips & Tricks

• Roast Vegetables Perfectly: Don’t overcrowd the baking sheet when roasting the vegetables. Overcrowding will steam the vegetables instead of roasting them, resulting in a less desirable texture and flavor. Use two baking sheets if necessary.
• Prevent Soggy Crust (Even Though It’s Crustless): While this recipe is crustless, the roasted vegetables can still release moisture. Make sure the vegetables are well-drained after roasting to prevent a soggy bottom. You can also lightly dust the bottom of the quiche dish with breadcrumbs before adding the vegetables.
• Adjust Seasonings: Taste the egg mixture before pouring it into the quiche dish and adjust the seasonings as needed.
• Pre-shredded vs. Block Cheese: For the best flavor and melting, shred the Gruyere cheese yourself from a block rather than using pre-shredded cheese, which often contains anti-caking agents that can affect its melting properties.

Serving & Storage Suggestions

This Roasted Vegetable and Gruyere Quiche is delicious served warm or at room temperature. It pairs perfectly with a simple mixed green salad dressed with a light vinaigrette. For a heartier meal, serve it alongside a bowl of soup.

Leftovers can be stored in the refrigerator for up to 3 days. To reheat, cover the quiche with foil and bake at 350°F (175°C) until warmed through, about 15-20 minutes. You can also reheat individual slices in the microwave.

Quiche can also be frozen for longer storage. Wrap the cooled quiche tightly in plastic wrap and then in aluminum foil. Freeze for up to 2 months. To thaw, transfer the quiche to the refrigerator overnight. Reheat as directed above.
