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, take a moment to grease a 9-inch pie dish or a skillet with olive oil. This step is crucial for ensuring your Crustless Zucchini Tomato Quiche doesn’t stick, which will make for an easier slicing experience once it’s baked to perfection.
Step 2: Cook the Vegetables
In a skillet over medium heat, add a splash of olive oil. Sauté one diced onion for about 3 minutes until it’s translucent and fragrant, then add in the shredded zucchini and minced garlic. Cook for an additional 5–6 minutes until the zucchini is tender and slightly golden. Remove from heat and allow the mixture to cool slightly before assembling the quiche.
Step 3: Whisk the Egg Mixture
In a large mixing bowl, carefully whisk together a dozen large eggs, 1 cup of milk or heavy cream, and season with salt, pepper, dried basil, and oregano. Stir until the mixture is smooth and combined, creating the base that will bind all your delicious vegetables and cheese in the Crustless Zucchini Tomato Quiche, ensuring every bite is packed with flavor.
Step 4: Assemble the Quiche
Spread the cooked zucchini and onion mixture evenly in the bottom of the prepared pie dish. Next, add diced tomatoes on top, taking care to distribute them evenly. Sprinkle a generous handful of mozzarella and Parmesan cheese across the top for richness. Finally, pour the egg mixture over the layered veggies and cheese, ensuring everything is well combined.
Step 5: Bake to Golden Perfection
Carefully place the assembled Crustless Zucchini Tomato Quiche into the preheated oven. Bake for 35–40 minutes, or until the top is lightly golden and the quiche has set completely. You’ll know it’s ready when a gentle shake reveals that it has firmed up nicely, promising a light yet satisfying dish.
Step 6: Rest and Serve
Once baked, remove the quiche from the oven and let it cool for about 10 minutes. This resting period is essential as it allows the quiche to firm up further, making for cleaner slices. After resting, slice into wedges and serve warm, perhaps paired with a fresh salad for a delightful and healthy meal.
