Prep & Preheat: Preheat your oven to 375°F (190°C). Lightly brush an oval or round baking dish with olive oil. 🖼️
Sauté the Onion Base: Heat 1 tbsp olive oil in a skillet over medium heat. Add chopped onion and garlic, cooking for 5 minutes until soft and fragrant. Spread this mixture evenly across the bottom of the prepared baking dish. 🧅🧄
Slice the Veggies: Slice the squash, zucchini, beets, and tomatoes into thin, uniform rounds (about 1/8-inch thick). 🔪
Arrange in a Spiral: Stack the vegetable slices in an alternating color pattern (e.g., beet, squash, zucchini, tomato). Pack them tightly vertically or in a circular spiral throughout the baking dish. 🌈
Season & Oil: Drizzle the remaining 2 tbsp olive oil evenly over the top. Season generously with salt, cracked black pepper, and fresh thyme. Top with crumbled goat cheese and parmesan! 🧀🌿
Bake to Perfection: Cover the dish with foil and bake for 30 minutes. Remove the foil and bake uncovered for an additional 20 minutes, until the vegetables are tender and the edges are beautifully roasted and crispy! ⏲️
Garnish & Serve: Garnish with fresh rosemary sprigs and serve warm right out of the oven alongside your favorite roasted main dish! 🍽️✨
