Ingredients You’ll Need

For the Egg Base:

• 8 large eggs
• 1 cup whole milk (or half-and-half for extra richness)
• ¼ teaspoon sea salt
• ¼ teaspoon black pepper
• ½ teaspoon dried herbs (thyme, herbes de Provence, or Italian seasoning)

For the Vegetable Filling:

• 2 tablespoons olive oil
• 1 medium onion, diced
• 2 cloves garlic, minced
• 1 red bell pepper, diced
• 1 cup fresh spinach, roughly chopped
• 1 medium zucchini, thinly sliced or diced
• 1 cup broccoli florets, cut small

For the Cheese:

• 1 cup shredded cheese (a mix of cheddar and mozzarella works beautifully)
• ¼ cup grated Parmesan cheese

Optional Add-ins:

• Cherry tomatoes, halved
• Fresh herbs (chives, basil, or parsley)
• ¼ teaspoon red pepper flakes (for a slight kick)

Step-by-Step Instructions

Step 1: Prepare Your Kitchen

Preheat your oven to 350°F (175°C). Grease a 9-inch pie dish or quiche pan with butter or cooking spray. This prevents sticking and makes serving easier.

Step 2: Sauté the Vegetables

Heat olive oil in a large skillet over medium heat. Add the diced onion and cook until translucent, about 3-4 minutes. Add the minced garlic and cook for another 30 seconds until fragrant. Next, add the bell pepper, zucchini, and broccoli. Sauté for 5-7 minutes until the vegetables are just tender but still have a slight bite. In the last minute, add the spinach and stir until wilted.

Step 3: Prepare the Egg Mixture

In a large bowl, whisk together eggs, milk, salt, pepper, and dried herbs until well combined. The mixture should be light and airy.

Step 4: Assemble the Quiche

Transfer the sautéed vegetables to your prepared pie dish, spreading them evenly. Sprinkle half of your shredded cheese over the vegetables. Pour the egg mixture over the vegetables and cheese, then top with the remaining shredded cheese and Parmesan.

Step 5: Bake to Perfection

Place the quiche in the preheated oven and bake for 35-40 minutes. The quiche is done when the center is set with just a slight jiggle and the top is golden brown.

Step 6: Rest and Serve

Let the quiche rest for 5-10 minutes before slicing. This allows it to set completely and makes for cleaner slices. Garnish with fresh herbs and serve warm or at room temperature.

Pro Tips for Success

• Moisture Management: To prevent a soggy quiche, make sure to cook most of the moisture out of your vegetables before adding them to the egg mixture.
• Cheese Strategy: Layering some cheese below and above the egg mixture creates wonderful pockets of flavor and helps form a beautiful golden crust on top.
• Don’t Overbeat: Whisk the eggs just until combined. Overbeating can incorporate too much air and result in a quiche that puffs up dramatically, then falls.
• Test for Doneness: Insert a knife in the center of the quiche – if it comes out clean, your quiche is perfectly cooked.
• Make Ahead: You can sauté the vegetables the night before and store them in the refrigerator to make morning assembly even quicker.

One of the best aspects of a crustless vegetable quiche is how well it keeps after baking. Here’s how to enjoy it beyond your initial brunch:

Top 4 FAQs About Crustless Vegetable Quiche

Can I prepare crustless vegetable quiche ahead of time?

Absolutely! You can assemble the entire quiche the night before and refrigerate it unbaked. In the morning, allow it to sit at room temperature for about 10 minutes before baking. You may need to add 5-10 minutes to the baking time if starting from cold.

What vegetables work best in a crustless quiche?

The beauty of this recipe is its flexibility. Good options include bell peppers, spinach, kale, zucchini, mushrooms, broccoli, asparagus, and cherry tomatoes. Just make sure to cook vegetables with high water content (like mushrooms and zucchini) beforehand to reduce moisture.

How do I know when my crustless quiche is done?

A perfectly done quiche should be set around the edges but maintain a very slight jiggle in the center. Insert a knife into the center – it should come out clean or with just a bit of moisture. The top should be golden brown and slightly puffed.

Can I make a dairy-free version of this crustless vegetable quiche?

Yes! Substitute the milk with unsweetened almond milk, coconut milk, or another plant-based milk. Replace the cheese with your favorite dairy-free alternatives or nutritional yeast for a cheesy flavor. The texture will be slightly different but still delicious.
