Ingredients

Gather your ingredients, and you’ll see just how approachable this dish is. It’s a beautiful way to celebrate the fresh, vibrant flavors of summer vegetables.

• 1 tablespoon oil (your favorite neutral cooking oil like olive or vegetable oil will work beautifully)
• ½ cup onion, chopped
• 1 garlic clove, minced
• 2 medium tomatoes, diced
• 3 cups zucchini, chopped (about 2 medium zucchini)
• 6 mushrooms, sliced (cremini or white button mushrooms are excellent choices)
• 4 eggs, beaten
• 2 ounces cheddar cheese, shredded
• Salt and pepper, to taste

Equipment Needed

The beauty of this recipe lies in its simplicity, and you won’t need a fancy arsenal of tools.

• A large oven-safe skillet (cast iron is ideal for its even heating and ability to go from stovetop to oven)
• A whisk (for beating the eggs)
• A cutting board and knife (for prepping the vegetables)
• An oven

Instructions

The beauty of this crustless quiche is that it comes together entirely in one skillet, minimizing cleanup and maximizing flavor development. Follow these steps for a delightful, fuss-free meal.

1. Begin by preheating your oven to 400°F (200°C).
2. Place your large oven-safe skillet over medium-low heat and add the oil.
3. Once the oil is shimmering, add the chopped onion. Sauté the onion, stirring frequently, until it becomes translucent and soft, which should take about 5–7 minutes. This gentle cooking process coaxes out the onion’s natural sweetness.
4. Now, add the minced garlic clove to the skillet. Cook for just 30 seconds more, stirring constantly, until fragrant. Be careful not to burn the garlic, as it can turn bitter.
5. Introduce the diced tomatoes and chopped zucchini to the skillet. Continue to cook, stirring frequently, for about 2 minutes. The vegetables will start to soften slightly.
6. Add the sliced mushrooms to the mix. Cook for one minute more, still stirring frequently. At this stage, the vegetables should be tender-crisp.
7. Remove the skillet from the heat. This is crucial before adding the eggs to prevent them from scrambling prematurely.
8. Pour the beaten eggs over the cooked vegetables in the skillet. Gently mix well to ensure the eggs are evenly distributed amongst the vegetables.
9. Sprinkle the shredded cheddar cheese evenly over the top of the egg and vegetable mixture.
10. Carefully transfer the skillet into the preheated oven.
11. Bake for 25 minutes, or until the quiche is set and golden brown on top. You can check for doneness by gently jiggling the skillet; the center should no longer be liquid and should appear firm. A toothpick inserted into the center should come out clean, with no wet egg attached.
12. Once baked, carefully remove the skillet from the oven. Allow it to cool for a few minutes before attempting to slice.
13. Cut into wedges directly from the skillet and serve.

Expert Tips & Tricks

As a chef, I’ve learned that a few little touches can elevate even the simplest of dishes. For this crustless zucchini quiche, consider these insights:

• Squeeze Excess Moisture from Zucchini: While this recipe doesn’t explicitly call for it, if you find your zucchini is particularly watery, a quick squeeze through a clean kitchen towel after chopping can prevent a slightly soggy quiche.
• Cheese Varieties: While cheddar is a classic, feel free to experiment! Monterey Jack, Gruyère, or even a sprinkle of Parmesan would be delightful additions.
• Herb Power: A handful of fresh herbs like chives, parsley, or dill, stirred in with the eggs or sprinkled on top before baking, can add an extra layer of fresh flavor.
• Even Cooking: Ensure your oven temperature is accurate. An oven thermometer is a great investment for consistent baking results. If your oven tends to cook hotter or cooler, adjust the baking time accordingly.

Serving & Storage Suggestions

This One-Skillet Crustless Zucchini Quiche is wonderfully versatile. It’s fantastic served warm, straight from the oven, for a satisfying brunch or a light dinner. For a more substantial meal, consider pairing it with a crisp green salad dressed with a lemon vinaigrette or some sweet red grapes, as I mentioned earlier.

Leftovers can be stored, covered, in the refrigerator for up to 3 days. When ready to reheat, gently warm individual slices in a microwave or a low oven until heated through. While it’s best enjoyed fresh, it still retains a pleasant texture even after refrigeration.

• Vegetable Medley: Feel free to swap out or add other quick-cooking vegetables. Bell peppers (any color, finely diced), spinach (wilted and squeezed dry), or even finely chopped broccoli florets would be delicious additions.

• Spicy Kick: A pinch of red pepper flakes added with the garlic can give this quiche a pleasant, subtle heat.

FAQs

Q: Can I make this quiche ahead of time?
A: While it’s best served fresh, you can prepare the sautéed vegetables a day in advance. Store them in an airtight container in the refrigerator, then proceed with the recipe by adding the eggs and cheese and baking when ready.

Q: What if I don’t have an oven-safe skillet?
A: If your skillet isn’t oven-safe, you can sauté the vegetables as directed, then transfer them to a greased pie plate or baking dish before adding the eggs and cheese and baking.

Q: How do I prevent the bottom from getting soggy?
A: Ensuring your vegetables are not overly watery is key. If using very watery vegetables like zucchini, a quick pat down with paper towels after chopping can help. Baking in a hot oven also helps set the bottom quickly.

Q: Can I use different types of eggs?
A: While standard chicken eggs are used here, you could experiment with a mix of chicken and duck eggs for a richer flavor, but be mindful of the different cooking properties.

Q: What’s the best way to cut this without it falling apart?
A: Allow the quiche to cool for at least 5-10 minutes after removing it from the oven. This allows the custard to fully set, making it easier to slice cleanly.
