Crustless Zucchini Tomato Quiche Ingredients

• Here’s what you’ll need to make this delicious dish:

For the Base

  • Olive Oil – Adds flavor and helps cook the vegetables; feel free to substitute with avocado oil for a different taste.
  • Small Onion – Provides a savory base flavor that you can enhance by using shallots instead.
  • Zucchini – Keeps the quiche moist with a subtle sweetness; ensure to grate or thinly slice it and squeeze out excess moisture for the best results.

For the Filling

  • Large Eggs – The main structure of the quiche; using fresh eggs will give you the best texture.

  • Grated Parmesan Cheese – Adds sharpness and depth; swap it out for nutritional yeast if you want a vegan option.

Seasoning

  • Garlic – Infuses the dish with aromatic flavor; omit if you prefer a milder version.
  • Dried Basil – A sweet and aromatic herb that pairs beautifully with zucchini; fresh basil can also be a great substitute.
  • Dried Oregano – Provides an extra layer of flavor; Italian seasoning can serve as an alternative.
  • Salt – Essential for enhancing the overall flavor of the dish.
  • Black Pepper – Adds a dash of mild heat; feel free to adjust according to your taste.

Step‑by‑Step Instructions for Crustless Zucchini Tomato Quiche

Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Crustless Zucchini Tomato Quiche will bake evenly. While the oven warms up, grab a 9-inch pie dish or quiche pan and grease it lightly with olive oil or cooking spray, making sure to coat it evenly for easy release after baking.

Step 2: Sauté the Vegetables
In a skillet over medium heat, add a splash of olive oil. Once the oil is shimmering, toss in a small chopped onion and sauté for about 3 minutes until it’s soft and translucent. Next, add the grated zucchini and minced garlic, stirring occasionally for an additional 5-6 minutes until the zucchini is tender and any excess moisture has evaporated. Remove from heat and let it cool slightly.

Step 3: Whisk Together the Filling
In a large mixing bowl, crack the large eggs and whisk them until well-beaten. Pour in the milk and heavy cream, then add the dried basil, oregano, salt, and black pepper. Continue whisking until the mixture is smooth and well-combined, ensuring that all ingredients meld together beautifully in this filling for the Crustless Zucchini Tomato Quiche.

Step 4: Assemble the Quiche
Now, it’s time to layer! Start by spreading the sautéed zucchini and onion mixture evenly across the bottom of your prepared pie dish. Follow this by adding sliced tomatoes on top, then sprinkle a generous amount of shredded mozzarella and grated Parmesan cheese to enhance the flavors. Finally, pour the egg mixture evenly over the entire assembly, ensuring all ingredients are well-distributed.

Step 5: Bake the Quiche
Carefully place the assembled quiche in your preheated oven. Bake for about 35-40 minutes until the top is golden brown and the center has set—give it a gentle jiggle to check for doneness. You want the surface to feel firm but not overly dry, ensuring every bite of your Crustless Zucchini Tomato Quiche remains moist and delicious.

Step 6: Cool and Serve
Once baking is complete, carefully remove the quiche from the oven and let it cool in the pan for about 10 minutes. This resting time allows the quiche to firm up slightly for easier slicing. Once cooled, cut into wedges and serve warm or at room temperature, savoring a delightful blend of flavors in every bite.

Storage Tips for Crustless Zucchini Tomato Quiche

Fridge: Store leftovers in an airtight container for up to 4 days. Make sure the quiche is completely cooled before sealing to maintain freshness.

Freezer: For longer storage, slice the quiche and freeze in an airtight container for up to 2 months. Wrap each slice individually to prevent freezer burn.

Reheating: When ready to enjoy, reheat slices in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through. The Crustless Zucchini Tomato Quiche is best enjoyed fresh!

Serving Tip: Pair reheated slices with a fresh salad for a delightful meal any time of day.

What to Serve with Crustless Zucchini Tomato Quiche

The delightful aroma of a freshly baked quiche is only enhanced by the perfect pairings that elevate your meal to new heights.

  • Fresh Garden Salad: A light mix of greens, cherry tomatoes, and cucumbers adds a crisp texture that complements the creamy quiche beautifully. A zesty vinaigrette will tie the flavors together.

  • Crusty Bread: A warm baguette or homemade artisan bread offers a satisfying crunch. It’s perfect for soaking up any of the rich egg and cheese mixture left on your plate.

  • Roasted Vegetables: Seasonal veggies like bell peppers, asparagus, or broccoli provide a delicious contrast in both flavor and texture, making your meal both colorful and nutritious.

  • Herbed Yogurt Dip: A cool, creamy dip made from Greek yogurt with fresh herbs brings a tangy twist that balances the richness of the quiche. It’s a refreshing accompaniment that keeps things light.

  • Savory Fruit Salsa: A sweet and spicy fruit salsa, like peach or pineapple, adds an unexpected flair. The touch of acidity brightens each bite of quiche delightfully.

  • Chilled White Wine: A glass of crisp Sauvignon Blanc or Chardonnay elevates the dining experience. The wine’s acidity perfectly cuts through the richness of the quiche, making each sip a pleasure.

Expert Tips for Crustless Zucchini Tomato Quiche

  • Squeeze Zucchini: Always squeeze out excess moisture from the grated zucchini to prevent a soggy Crustless Zucchini Tomato Quiche.

  • Flavor Experimentation: Don’t hesitate to mix in other vegetables like spinach or mushrooms. Different cheeses like feta or sharp cheddar can also bring new dimensions to the flavor.

  • Make-Ahead Magic: Bake your quiche a day or two in advance and keep it in the fridge. Just reheat slices as needed for a quick, delicious meal.

  • Check for Doneness: When baking, gently jiggle the quiche; it should be firm but slightly jiggly in the center. Overbaking can lead to a dry texture.

Crustless Zucchini Tomato Quiche Recipe FAQs

What kind of zucchini should I use for this quiche?
For the best results, I recommend using firm, medium-sized zucchini. Look for ones that are vibrant green with smooth skin and no dark spots. Avoid overly large zucchinis, as they may have a spongy texture and more seeds.

How should I store leftovers?
Absolutely! Store any leftover Crustless Zucchini Tomato Quiche in an airtight container in the refrigerator. It will stay fresh for up to 4 days. Make sure it’s cooled completely before sealing to help maintain that delightful flavor!

Can I freeze this quiche?
Yes, you can! Slice your quiche into individual portions, wrap each slice tightly in plastic wrap, and place them in an airtight container or freezer bag. It will keep well in the freezer for up to 2 months. When you’re ready to enjoy, simply reheat in a 350°F (175°C) oven for about 15-20 minutes, and it’ll be as good as new!

What can I do if my quiche comes out too watery?
No worries! If your quiche turns out watery, it’s often because excess moisture was not removed from the zucchini. To prevent this in the future, always grate or slice the zucchini and then squeeze it gently in a clean kitchen towel to remove as much moisture as possible before adding it to the mix.

Is this recipe suitable for gluten-free diets?
Yes! This Crustless Zucchini Tomato Quiche is a fantastic gluten-free option since it skips the crust entirely. Always double-check all your ingredients, especially your cheese and processed items, to ensure they are confirmed gluten-free.

Can I personalize the ingredients in the quiche?
Very much so! This recipe is highly customizable. Feel free to add your favorite vegetables like spinach or bell peppers, or switch cheeses for mozzarella, cheddar, or even feta. The more, the merrier when it comes to flavor combinations!
