Elevate your Friday nights with this irresistible Vegetarian Onion and Tomato Quiche, a perfect blend of sweet caramelized onions, juicy cherry tomatoes, and a rich, creamy egg filling infused with thyme. Built on a buttery, pre-baked pie crust—store-bought or homemade—it’s layered with sautéed onions and fresh tomatoes before being blanketed in a luxurious mixture of eggs, heavy cream, milk, and melty shredded cheese like Gruyère or cheddar. Baked to golden perfection in under an hour, this easy yet elegant vegetarian recipe is ideal for entertaining, a cozy dinner, or even meal-prepping for the weekend. Serve warm alongside a crisp green salad for a truly satisfying meal!
Preheat your oven to 375°F (190°C).
Place the pie crust in a 9-inch pie dish. Use a fork to prick the bottom of the crust to prevent bubbling. Pre-bake the crust for 10 minutes and set it aside to cool slightly.
Heat the olive oil in a skillet over medium heat. Slice the yellow onions thinly and sauté them with a pinch of salt until caramelized, about 10-15 minutes. Stir occasionally to prevent burning.
Slice the cherry tomatoes in half and set them aside.
In a mixing bowl, whisk together the eggs, heavy cream, milk, shredded cheese, dried thyme, salt, and black pepper until smooth and well combined.
Spread the caramelized onions evenly over the pre-baked pie crust. Place the halved cherry tomatoes on top, cut side up.
Pour the egg and cream mixture over the onions and tomatoes, allowing it to settle evenly.
Bake the quiche in the preheated oven for 35-40 minutes, or until the filling is set and the top is lightly golden.
Remove the quiche from the oven and let it cool for 5-10 minutes before slicing. Serve warm and enjoy!
