Step‑by‑Step Instructions for Crustless Zucchini Tomato Quiche
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grease a 9-inch pie dish with a light coat of olive oil or non-stick spray. This will allow the quiche to release easily after baking, ensuring a beautifully presented Crustless Zucchini Tomato Quiche.
Step 2: Cook the Vegetables
In a large skillet, heat a tablespoon of olive oil over medium heat. Add the finely chopped onion and sauté for about 3 minutes until softened and fragrant. Then, stir in the thinly sliced zucchini and minced garlic, cooking for an additional 5-6 minutes until the zucchini is tender. Once cooked, set the mixture aside to cool slightly.
Step 3: Prepare the Egg Mixture
In a mixing bowl, crack in several large eggs and add whole or 2% milk, along with the optional heavy cream if you desire extra richness. Whisk together until the mixture is smooth, then incorporate dried basil, oregano, salt, black pepper, and red pepper flakes for flavor. This flavorful base will bind the ingredients beautifully in your Crustless Zucchini Tomato Quiche.
Step 4: Assemble the Quiche
Spread the sautéed vegetable mixture evenly across the bottom of the greased pie dish. Next, layer the diced tomatoes on top, ensuring they are distributed evenly. Sprinkle a generous amount of shredded mozzarella and grated Parmesan cheese over the vegetables. This creates a delightful cheesy layer that enhances the quiche’s texture and taste.
Step 5: Combine and Pour
Once the cheese is added, gently pour the prepared egg mixture over the assembled layers in the pie dish. Make sure that the egg mixture covers all the vegetables and cheese evenly, which will create that lovely custardy texture in your Crustless Zucchini Tomato Quiche.
Step 6: Bake the Quiche
Carefully place the pie dish in the preheated oven and bake for 35-40 minutes. Keep an eye on it, and look for a golden top and a firm, set middle—this indicates that your quiche is perfectly cooked. A gentle jiggle in the center is fine but should not be overly liquid.
Step 7: Cool and Slice
Once baked, remove the quiche from the oven and allow it to cool for about 10 minutes on a wire rack. This resting period helps the quiche firm up, making it easier to slice. After cooling, cut into wedges and serve warm, enjoying the delightful flavors of the Crustless Zucchini Tomato Quiche.

Crustless Zucchini Tomato Quiche Recipe FAQs
How do I choose the best zucchini and tomatoes for this recipe?
Absolutely! When selecting zucchini, look for firm, unblemished vegetables with a rich green color. Avoid those with dark spots or soft spots, as they may be overripe. For tomatoes, opt for ripe Roma or cherry tomatoes that feel slightly soft when gently squeezed, indicating sweetness and juiciness.
How should I store leftover Crustless Zucchini Tomato Quiche?
To keep your quiche fresh, store any leftovers in an airtight container in the fridge for up to 4 days. Be sure to let the quiche cool completely before sealing it to avoid condensation, which can make the texture soggy.
Can I freeze the quiche for later use?
Yes, indeed! To freeze, wrap the cooled quiche tightly in plastic wrap, then cover it with aluminum foil. This way, it’ll keep well for up to 2 months. When you’re ready to enjoy it, thaw it overnight in the fridge before reheating in the oven at 350°F (175°C) for about 15-20 minutes until warmed through.
What should I do if my quiche turns out soggy?
If you find your quiche is soggy, it may be due to excess moisture from the zucchini. To avoid this, always remember to squeeze out excess liquid after salting the sliced zucchini. In case it does get soggy, you can set slices on a baking sheet in a preheated oven for 5-10 minutes to help crisp it up again.
Is this recipe suitable for people with dietary restrictions?
Very much so! The Crustless Zucchini Tomato Quiche is gluten-free and low-carb, making it a wonderful option for individuals with these dietary needs.
