Step‑by‑Step Instructions for Crustless Zucchini Tomato Quiche
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures the oven is hot and ready when it’s time to bake your Crustless Zucchini Tomato Quiche. A fully preheated oven will help achieve that perfect golden top and set filling.
Step 2: Prepare the Vegetables
Wash and slice the zucchini thinly, aiming for even pieces that will cook uniformly. Halve the cherry tomatoes, releasing their juiciness. If you choose to include onion, sauté it in a skillet over medium heat until soft and lightly golden, about 5 minutes. Set the sautéed onion aside to cool.
Step 3: Make the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, minced garlic, salt, pepper, and your chosen herbs until fully combined and slightly frothy, about 1-2 minutes. This vibrant mixture is the heart of your Crustless Zucchini Tomato Quiche, binding everything deliciously together. Stir in half of the shredded cheese until evenly distributed.
Step 4: Assemble the Quiche
Lightly grease a baking dish with cooking spray or oil to prevent sticking. Spread the sliced zucchini, halved tomatoes, and cooled onion evenly across the bottom of the dish. This colorful veggie layer will provide a foundation for your quiche, distribution key to achieving consistent flavors throughout.
Step 5: Add the Egg Mixture
Carefully pour the egg mixture over the layered vegetables, ensuring even coverage. The egg mixture should be almost level with the veggies; it will puff up beautifully in the oven. Finally, sprinkle the remaining cheese generously on top to create a deliciously cheesy crust as it bakes.
Step 6: Bake the Quiche
Place the baking dish in the preheated oven and bake for 35-40 minutes. Watch as the top turns a golden brown and the center appears set rather than jiggly. You can gently jiggle the dish; if it seems firm, it’s ready!
Step 7: Cool and Serve
Once baked, remove your Crustless Zucchini Tomato Quiche from the oven and let it cool for about 10 minutes. This cooling period allows the quiche to firm up, making slicing easier. Serve warm, at room temperature, or chilled for the best enjoyment.
