Step‑by‑Step Instructions for Herb-Infused Crustless Zucchini Quiche

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is perfect for baking the Herb-Infused Crustless Zucchini Quiche evenly, ensuring a fluffy and set center. While the oven warms up, gather your ingredients to streamline the cooking process, creating a seamless flow in your kitchen.

Step 2: Prepare the Pan
Generously coat a pie dish or quiche pan with ghee or avocado oil. This oil not only prevents sticking but also adds a subtle richness to the quiche. Make sure to cover the edges thoroughly so that every slice comes out perfectly intact, ready to impress your family and friends.

Step 3: Sauté the Zucchini
In a large skillet, heat 1 tablespoon of ghee or avocado oil over medium-high heat. Once hot, add the sliced zucchini in a single layer. Cook for about 2-3 minutes until they develop a lovely golden-brown color, then flip them to brown the other side. Remove the zucchini from the skillet and set aside, allowing the delicious aroma to fill the kitchen.

Step 4: Cook the Aromatics
Reduce the heat to medium and add the remaining tablespoon of ghee or avocado oil to the skillet. Sauté the diced onion for 3-4 minutes until it turns translucent and begins to brown. Add the finely chopped garlic and cook for an additional minute, stirring constantly to avoid burning. Incorporate the baby spinach, cooking just until it wilts, then remove the mixture from heat.

Step 5: Layer the Vegetable Mixture
Take the sautéed onion, garlic, and spinach, and spread it evenly across the bottom of the greased quiche pan. This flavorful base will provide a delightful foundation for your Herb-Infused Crustless Zucchini Quiche, ensuring that every bite is packed with nutritious goodness.

Step 6: Add Zucchini and Tomato Layers
Carefully arrange most of the cooked zucchini rounds and sliced tomatoes on top of the spinach mixture. Reserve a small handful of zucchini and tomatoes for later garnishing. To finish this layer, sprinkle chopped fresh basil generously over the vegetables, ensuring the quiche is filled with vibrant flavors.

Step 7: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, plant-based milk, salt, and freshly ground black pepper until the mixture is smooth and well combined. This egg mixture is the key to binding all the ingredients in your Herb-Infused Crustless Zucchini Quiche, providing a light and airy texture when baked.

Step 8: Assemble the Quiche
Gently pour the egg mixture over the layered vegetables in the quiche pan. Take care to cover all the ingredients evenly, which will help them blend beautifully while baking. This step is crucial for achieving that luscious, custard-like filling that will make your quiche a hit.

Step 9: Bake to Perfection
Take the assembled quiche and place it in the preheated oven. Bake for 35-40 minutes, or until the center is set and a toothpick inserted in the middle comes out clean. You’ll know it’s done when the top is lightly golden and has a gentle firmness, promising a delightful herb-infused flavor in every slice.

Step 10: Cool and Garnish Before Serving
Once baked, allow the quiche to cool slightly before cutting it into wedges. For an extra touch of flavor and presentation, garnish with additional fresh basil. This simple yet beautiful finishing touch enhances the appearance and aroma of your Herb-Infused Crustless Zucchini Quiche, making it a perfect centerpiece for any meal.

Herb-Infused Crustless Zucchini Quiche Variations

Feel free to get creative and make this quiche your own with these delightful twists that will elevate your meal!

  • Dairy-Free: Swap plant-based milk for coconut milk to add a creamy, tropical flavor to the quiche.

  • Spicy Kick: Add diced jalapeños or red pepper flakes to the sautéed veggies for a delightful heat that warms the soul.

  • Protein Boost: Mix in cooked and crumbled sausage or bacon for a hearty version that's perfect for brunch gatherings.

  • Herby Fusion: Incorporate fresh dill or chives alongside the basil to impart a unique flavor profile that awakens your taste buds.

  • Cheesy Indulgence: Sprinkle mozzarella or feta cheese into the vegetable mix for a melty, savory addition that everyone will love.

  • Other Veggies: Experiment with roasted bell peppers or mushrooms to create a diverse medley of flavors and textures in every bite.

  • Crusty Option: Serve in a pre-baked phyllo dough shell to indulge in a crispy texture while keeping it light.

  • Sweet and Savory: Add a handful of grated carrots for a subtle sweetness, balancing the savory elements beautifully.

Whether you choose to stick to tradition or venture off the beaten path, this quiche is a canvas waiting for your culinary art. Pair it with a refreshing vinaigrette-dressed salad or some of my crispy roasted breakfast potatoes for the ultimate dining experience!

Make Ahead Options

These Herb-Infused Crustless Zucchini Quiches are ideal for meal prep! You can chop the vegetables (zucchini, onion, garlic, and spinach) and store them in the refrigerator up to 3 days in advance. You can also whisk the egg and plant-based milk mixture ahead of time and refrigerate it for up to 24 hours. When you’re ready to serve, simply sauté the veggies as instructed, layer them in the pan, pour the egg mixture on top, and bake as directed. This approach ensures you can enjoy a homemade, nutritious meal on busy weeknights, saving time without sacrificing flavor!

What to Serve with Herb-Infused Crustless Zucchini Quiche

Elevate your dining experience with dishes that beautifully complement this delightful quiche.

  • Mixed Green Salad: A light salad with a zesty vinaigrette adds brightness and crunch, balancing the creamy quiche perfectly.

  • Crispy Roasted Breakfast Potatoes: These golden, seasoned potatoes bring a hearty texture to your meal, making it satisfying and wholesome.

  • Crusty Bread: A slice of crusty artisan bread provides the ideal canvas for any remaining quiche, soaking up flavors and enhancing the dish.

  • Herb-Infused Olive Oil: Drizzle some herb-infused olive oil over the quiche for an extra burst of flavor that ties the whole dish together.

Expert Tips for Herb-Infused Crustless Zucchini Quiche

  • Use Fresh Ingredients: The better the quality of your zucchini, spinach, and herbs, the more flavorful your Herb-Infused Crustless Zucchini Quiche will be.

  • Avoid Soggy Bottom: Make sure to sauté your zucchini thoroughly to remove excess moisture before layering them in the quiche.

  • Whisk Well: Ensure your eggs and plant-based milk are fully combined; this will give your quiche a light, fluffy texture.

  • Customize Your Veggies: Feel free to add other vegetables like bell peppers or mushrooms—just make sure to sauté them first to enhance their flavors and prevent sogginess.

  • Check for Doneness: A toothpick inserted in the center should come out clean. If in doubt, bake it a little longer, as undercooked quiche can be disappointing.

How to Store and Freeze Herb-Infused Crustless Zucchini Quiche

Fridge: Place leftover quiche in an airtight container and refrigerate for up to 4 days to keep it fresh and flavorful.

Freezer: For long-term storage, freeze individual pieces wrapped in plastic wrap and foil for up to 3 months. This allows you to enjoy homemade goodness anytime!

Reheating: To thaw, simply remove the quiche from the freezer and place it in the fridge overnight. Reheat in the microwave (30-45 seconds per slice) or bake in a preheated 350°F oven for 10-15 minutes until warmed through.

Serving Tip: Enjoy it warm or cold; it’s a versatile dish that stays delicious no matter how you serve it!

Herb-Infused Crustless Zucchini Quiche Recipe FAQs

How do I choose the best zucchini?
Absolutely! When selecting zucchini, look for firm, glossy skin without dark spots or blemishes. They should feel heavy for their size—this indicates they're juicy and fresh. For the best flavor, choose zucchinis that are about 6-8 inches long.

How should I store leftovers of the quiche?
Sure! To keep your Herb-Infused Crustless Zucchini Quiche fresh, store it in an airtight container in the refrigerator. It will remain tasty for up to 4 days. Just make sure it’s properly sealed to prevent moisture loss and maintain its deliciousness.

Can I freeze this quiche? How do I do it?
Yes, you can! To freeze individual slices of your Herb-Infused Crustless Zucchini Quiche, wrap each piece tightly in plastic wrap. Then, wrap them again in foil to prevent freezer burn. You can store these wrapped slices in the freezer for up to 3 months. When you’re ready to enjoy, thaw in the fridge overnight, then warm in a 350°F oven for 10-15 minutes for the best taste and texture.

What should I do if my quiche turns out soggy?
Very understandable! If your quiche is soggy, ensure you thoroughly sauté your zucchini before adding it to the quiche to release excess moisture. Moreover, avoid overloading the quiche with watery vegetables. Always bake until the center is firm—if the toothpick comes out wet, it needs a bit more time in the oven!

Is this quiche suitable for people with dietary restrictions?
Absolutely! This quiche is naturally gluten-free and can be easily made vegan by using a plant-based egg substitute in place of eggs. If you have nut allergies, make sure to choose a nut-free plant-based milk. Just be mindful of the ingredients in your chosen substitutes to ensure they align with your dietary needs.

Can I add other vegetables to this quiche?
Very much so! Feel free to get creative! You can add sautéed mushrooms, bell peppers, or kale to enhance the flavor and nutrition. Just remember to sauté them first, similar to the zucchini, to ensure you’re not introducing excess moisture which can affect the quiche’s texture. The more, the merrier!
