Step‑by‑Step Instructions for Herb-Infused Crustless Zucchini Quiche
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grease a pie dish generously with ghee or avocado oil to prevent sticking. This crustless zucchini quiche will bake evenly, creating a delicious golden top, so ensuring a well-greased pan is crucial.
Step 2: Sauté the Zucchini
In a skillet, heat 1 tablespoon of ghee or oil over medium heat. Add the zucchini coins and sauté for about 2-3 minutes on each side until they turn golden and slightly tender. This step enhances the flavor and helps to manage moisture, ensuring your crustless zucchini quiche doesn’t become soggy.
Step 3: Cook the Aromatics
Lower the heat and add another tablespoon of oil to the skillet. Add the diced onion and sauté for approximately 3-4 minutes until it becomes translucent and aromatic. Next, stir in minced garlic and cook for an additional minute, then add a handful of spinach, stirring until wilted, which adds a vibrant color to your dish.
Step 4: Layer the Vegetables
Spread the cooked onion, garlic, and spinach mixture evenly across the prepared pie dish. Next, layer the sautéed zucchini rounds and sliced tomatoes on top, making sure to reserve a few slices for garnish. This layering not only adds aesthetic appeal but also ensures each bite of the crustless zucchini quiche is full of flavor.
Step 5: Whisk the Custard Mixture
In a large bowl, whisk together medium or large eggs, your choice of plant-based milk, and a pinch of salt and pepper. The whipped mixture should be smooth and well-combined. Pour this egg mixture evenly over the vegetable layers in the pie dish, allowing it to settle into the spaces for a beautifully cohesive quiche.
Step 6: Bake to Perfection
Sprinkle the reserved zucchini and tomato slices atop the quiche before placing it in the preheated oven. Bake for 35-40 minutes, or until the center is set and a toothpick comes out clean. The quiche should have a golden-brown top and a slightly wobbly center that will firm up as it cools.
Step 7: Cool and Serve
Once baked, remove the crustless zucchini quiche from the oven and let it cool for 10-15 minutes. This resting period helps in easy slicing and enhances the texture. Before serving, garnish with fresh basil leaves for an extra touch of flavor and aroma that complements this delightful dish.
How to Store and Freeze Crustless Zucchini Quiche
Fridge: Store leftover crustless zucchini quiche in an airtight container in the refrigerator for up to 4 days. Reheat slices in the microwave or oven until warmed through.
Freezer: To freeze, cut the quiche into portions and wrap each slice individually in plastic wrap, then place them in a freezer-safe bag. Freeze for up to 3 months for best quality.
Thawing: Thaw overnight in the fridge before reheating. For a quick option, you can also reheat frozen slices directly from the freezer, though this may take a few extra minutes.
Reheating: To reheat, use an oven preheated to 350°F (175°C) for about 10-15 minutes, or until heated through and the texture is restored. Enjoy your delicious crustless zucchini quiche!

Crustless Zucchini Quiche Recipe FAQs
How do I choose the best zucchini for my quiche?
Absolutely! When selecting zucchini, look for small to medium-sized ones—they should be firm and have a shiny skin without any dark spots or soft spots. Avoid large zucchinis as they tend to be watery and may not provide the best texture for your quiche.

Store any leftovers in an airtight container in the refrigerator for up to 4 days. I recommend reheating individual slices in the microwave or oven until warmed through. This keeps them tasting fresh and delicious!

Very! To freeze, cut the quiche into portions and individually wrap each slice in plastic wrap before placing them in a freezer-safe bag. It can be frozen for up to 3 months. When you're ready to enjoy it again, thaw overnight in the fridge or reheat directly from the freezer—just allow a few extra minutes for heating.
What are some common mistakes to avoid while making this quiche?
One common mistake is not salting the zucchini beforehand; this helps draw out moisture and prevents a soggy quiche. Additionally, avoid overcrowding the pan during sautéing, as this can prevent proper browning and flavor development. Lastly, be sure to let the quiche rest after baking – it firms up and makes slicing much easier!
Is this crustless zucchini quiche suitable for special diets?
