Step‑by‑Step Instructions for Crustless Zucchini Tomato Quiche
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grease a 9-inch pie dish with olive oil or cooking spray to prevent sticking. This initial preparation sets the stage for a perfectly baked Crustless Zucchini Tomato Quiche that will hold its shape beautifully.
Step 2: Sauté the Vegetables
In a skillet over medium heat, add a splash of olive oil and let it warm. Once shimmering, toss in the chopped onion, sautéing for about 3 minutes until softened. Add diced zucchini and minced garlic, stirring frequently, allowing them to cook for an additional 5-6 minutes until the veggies are tender and fragrant, showcasing their vibrant colors.
Step 3: Whisk the Egg Mixture
In a large mixing bowl, crack in the eggs and pour in the milk and heavy cream. Using a whisk, blend them together until the mixture is smooth and well combined. Season the egg mixture with dried basil, oregano, salt, and pepper, ensuring a flavorful filling for your Crustless Zucchini Tomato Quiche that highlights the fresh vegetables.
Step 4: Layer the Vegetables
Carefully spread the sautéed zucchini and onion mixture evenly across the bottom of your greased pie dish. Next, arrange the diced tomatoes on top, creating a colorful layer that adds sweetness and acidity. This step creates a delicious base that will wonderfully complement the creamy egg filling.
Step 5: Add the Cheese
Sprinkle the shredded mozzarella cheese and grated Parmesan cheese over the vegetable layer, distributing it evenly. The cheese not only enhances the flavor but also adds that gooey, comforting texture that we all love in a quiche. The combination of cheeses will melt beautifully during baking, providing a delightful surprise.
Step 6: Combine and Pour
Carefully pour the whisked egg mixture over the layered vegetables and cheeses, ensuring everything is well-coated. This step brings together the flavors and textures in your Crustless Zucchini Tomato Quiche, creating a harmony of ingredients that meld as they bake. Make sure to fill the dish without overflowing for the perfect rise.
Step 7: Bake to Perfection
Slide the pie dish into your preheated oven. Allow the quiche to bake for 35–40 minutes, or until the top is set and lightly golden. A gentle jiggle in the center indicates the quiche is cooked through but still tender. Keep an eye on the color for that lovely golden brown finish that enhances the appeal.
Step 8: Cool and Serve
Once your Crustless Zucchini Tomato Quiche is done baking, remove it from the oven and let it cool for about 10 minutes. This resting period allows the quiche to firm up slightly, making it easier to slice. Serve warm or at room temperature, allowing everyone to revel in the comforting flavors and textures of this delightful dish.
