Step‑by‑Step Instructions for Crustless Zucchini Tomato Quiche

Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C) and grease a 9-inch pie dish or quiche pan with a little olive oil or cooking spray. This prepares the surface for your filling, ensuring easy release after baking. While the oven heats, gather your ingredients for the Crustless Zucchini Tomato Quiche to streamline your process.

Step 2: Sauté the Onion
In a skillet, heat 2 tablespoons of olive oil over medium heat. Once shimmering, add a diced onion and sauté for about 3 minutes, or until it becomes translucent and aromatic. This step builds a savory base for your quiche. Be careful not to brown the onions; you want them soft and sweet for the best flavor.

Step 3: Add Zucchini and Garlic
Next, add shredded zucchini and minced garlic to the skillet, stirring to combine. Cook for about 5-6 minutes until the zucchini is tender and has released some moisture. Don’t forget to squeeze out any excess liquid from the zucchini first; this keeps your Crustless Zucchini Tomato Quiche from becoming too watery. Once cooked, let the mixture cool slightly.

Step 4: Whisk the Egg Mixture
In a large mixing bowl, whisk together 6 large eggs, 1 cup of milk, and 1/2 cup of heavy cream until smooth. Then, add in your dried basil, oregano, a pinch of salt, black pepper, and optional red pepper flakes. Ensure the mixture is well-blended to create a rich, custardy filling for your quiche.

Step 5: Assemble the Filling
Spread the cooled zucchini and onion mixture evenly at the bottom of the prepared dish. Scatter chopped tomatoes over the vegetables before generously sprinkling half a cup of shredded mozzarella cheese and a quarter cup of grated Parmesan cheese on top. This layering of flavors is key to the deliciousness of the Crustless Zucchini Tomato Quiche.

Step 6: Pour and Bake
Pour the egg mixture evenly over the layered vegetables and cheese, ensuring everything is well combined. Bake in the preheated oven for approximately 35-40 minutes, or until the center is set and the top is lightly golden. You’ll know it’s done when a toothpick inserted in the center comes out clean.

Step 7: Cool and Serve
Once baked to perfection, remove the quiche from the oven and let it cool for about 10 minutes before slicing. This resting time helps it firm up beautifully. Serve warm or at room temperature, and enjoy this delightful, crustless dish with family or friends, perfect for any occasion.

Storage Tips for Crustless Zucchini Tomato Quiche

Fridge: Store leftover slices in an airtight container for up to 4 days. This keeps the flavors fresh and ready for your next meal!

Freezer: Wrap cooled slices tightly in foil or plastic wrap. Your crustless zucchini tomato quiche can be frozen for up to 2 months without losing its delightful texture.

Reheating: For best results, thaw in the fridge overnight before reheating in the oven at 350°F (175°C) for about 15-20 minutes until warmed through.

Serving Suggestions: Reheat individual portions in the microwave for a quick lunch option or serve slices warm with a side salad for a balanced meal.

Crustless Zucchini Tomato Quiche Recipe FAQs

What type of zucchini should I use for the quiche?
Absolutely! Look for fresh, firm zucchinis with smooth skin. Make sure they have a vibrant color and no dark spots all over, as this indicates overripeness. Choose smaller zucchinis for a sweeter flavor and less water content, which helps prevent your quiche from getting soggy.

How long can I store leftovers of the quiche?
You can store leftover slices of your Crustless Zucchini Tomato Quiche in an airtight container for up to 4 days in the refrigerator. This keeps the flavors fresh! Just be sure to let it cool completely before covering it, to prevent condensation.

Can I freeze the quiche, and how should I do it?
Yes! To freeze your crustless zucchini tomato quiche, let it cool thoroughly, then wrap individual slices tightly in foil or plastic wrap. Place them in a freezer-safe bag and label with the date. Properly stored, they can last for up to 2 months! When you’re ready to eat, thaw in the refrigerator overnight and reheat in the oven at 350°F (175°C) for 15-20 minutes.

What can I do if my quiche turns out watery?
Very! If your quiche becomes watery, the most common cause is excess moisture from the zucchini. To prevent this, always squeeze out the excess water after shredding it. You can also try layering the vegetables and cheese in a way that allows for better moisture absorption. If it still looks watery after baking, don’t worry! A quick trip back into the oven can help evaporate some of that extra liquid—just keep an eye on it!

Is this quiche suitable for someone with a dairy allergy?
Certainly! To make this Crustless Zucchini Tomato Quiche dairy-free, you can substitute regular milk with almond or oat milk and opt for dairy-free cheese alternatives. Just be sure to read labels to avoid any hidden dairy ingredients. This way, everyone can enjoy this healthy and delicious dish without worry!
