How To Make Crustless Zucchini Tomato Quiche
This quiche comes together in simple steps: you’ll sauté fresh veggies, whisk a flavorful egg custard, and bake until golden and set. The process is straightforward, making it perfect for cooks of any skill level. Let’s walk through each step to create a fluffy, savory quiche you’ll want to make again and again.
1. Preheat the oven to 375°F to ensure even baking and a nicely browned top.
2. Rub a baking dish with the butter to create a non-stick layer and a hint of richness.
3. Heat the olive oil in a skillet over medium heat until shimmering.
4. Add the onion and garlic and cook until the onion is translucent, about 3 minutes, stirring occasionally.
5. Add the zucchini and tomatoes and cook for 5 minutes until the vegetables are softened and most moisture has evaporated.
6. In a large bowl, whisk together the eggs, milk, oregano, basil, salt, and pepper until smooth and well blended.
7. Stir the cooked vegetables into the egg mixture, ensuring an even distribution of flavors.
8. Pour the mixture into the prepared baking dish, smoothing out the top with a spatula.
9. Sprinkle the shredded cheese and Parmesan evenly over the surface for a golden, cheesy crust.
10. Bake for 25 to 30 minutes until the quiche is set in the center and the top turns golden brown.
11. Let the quiche cool for 5 minutes before slicing and serving to allow it to firm up for clean slices.
Serving Suggestions
This versatile quiche shines on its own or paired with simple sides. Here are some tasty ways to serve it:
- Fresh salad: A crisp mixed green salad with a light vinaigrette adds brightness and contrasts the quiche’s creaminess.
- Crusty bread: Toast baguette or ciabatta slices for dipping into any cheesy pockets and soaking up juices.
- Salsa or pesto: Drizzle tomato salsa or basil pesto over each slice for an extra herbaceous kick.
- Soup accompaniment: Pair with a bowl of tomato basil or minestrone soup for a comforting, hearty meal.
Tips For Perfect Crustless Zucchini Tomato Quiche
Every home cook loves a few insider tweaks! These quick tips will help you get the fluffiest, most flavorful quiche every time:
- Whisking the eggs thoroughly helps create a light, airy texture in the finished quiche.
- Feel free to use a blend of cheeses such as mozzarella and cheddar for varied melting qualities and flavor.
- Fresh herbs like parsley or chives can add a bright, fresh flavor—just stir them into the mixture or sprinkle on top.
- Store leftovers in the refrigerator for up to three days to maintain the best texture and taste.
How To Store It
To keep your quiche tasting as good as day one, proper storage is key. Follow these methods to preserve texture and flavor:
- Refrigerate in an airtight container: Once the quiche has cooled completely, slice and store in a sealed container in the fridge for up to three days.
- Reheat gently: Warm individual portions in a preheated 350°F oven for 8–10 minutes to revive the creamy center and melty cheese.
- Freeze for longer storage: Wrap the cooled quiche tightly in plastic wrap and foil, then freeze for up to two months. Thaw overnight in the fridge before reheating.
- Serve chilled: On warm days, enjoy slices straight from the refrigerator for a firmer texture and refreshing bite.
Frequently Asked Questions
Here are quick answers to common questions about this quiche:
- How long does it take to prepare and bake this Crustless Zucchini Tomato Quiche?
It takes about 10 to 15 minutes to prepare—dicing the zucchini, tomatoes, chopping the onion and garlic, and whisking the eggs and milk—followed by 25 to 30 minutes of baking at 375°F. Allow an additional 5 minutes of cooling before slicing, for a total of around 45 to 50 minutes.
- How can I prevent the quiche from becoming soggy?
Cook the zucchini and tomatoes until they’ve released much of their moisture—about 5 minutes—then stir them into the egg mixture and let any excess liquid settle before pouring into the dish. Greasing the baking dish with butter also helps create a slight barrier between the vegetables and the eggs, reducing sogginess.
- Can I substitute or add other cheeses and herbs?
Yes. While the recipe calls for a combination of shredded cheese and Parmesan, you can use mozzarella, cheddar, or a blend of both. Fresh herbs such as parsley, chives, or basil can be stirred into the egg mixture or sprinkled on top before baking for extra flavor.
- What’s the best way to store and reheat leftovers?
Store any leftover quiche in an airtight container in the refrigerator for up to three days. To reheat, place individual slices in a preheated 350°F oven for 8–10 minutes or microwave on medium power for 1–2 minutes until warmed through.
- Can I make this quiche ahead of time or freeze it?
You can assemble the quiche, cover it, and refrigerate for up to 24 hours before baking. For freezing, bake fully, let it cool, then wrap tightly in plastic and foil. Freeze for up to two months. Thaw overnight in the refrigerator and reheat in a 350°F oven until warmed.
- How can I add protein to this quiche?
To boost protein, stir in cooked diced chicken, crumbled cooked sausage, or cooked bacon bits along with the zucchini and tomatoes before combining with the egg mixture. Ensure any added meats are fully cooked and drained of excess fat.
- My quiche top is browning too quickly. What should I do?
If the top is browning faster than the center sets, loosely cover the dish with foil halfway through the bake to prevent over-browning, then remove the foil during the last 5–10 minutes so the top can finish setting and turn golden.
- Is it necessary to whisk the eggs vigorously?
Yes. Whisking the eggs and milk thoroughly incorporates air, which helps create a light, fluffy texture in the quiche. This also ensures the dried oregano, basil, salt, and pepper are evenly distributed.
