A vibrant, roasted vegetable medley that's healthy, easy to clean up, and packed with Provencal flavor.
Nutrition (per serving)
There is something truly magical about the way late-summer vegetables transform when they hit a hot oven. While a traditional ratatouille requires standing over a stove and stirring a heavy pot, this sheet-pan version lets the oven do the heavy lifting. By roasting the eggplant, zucchini, and peppers at a high temperature, we achieve beautiful caramelized edges and a concentrated depth of flavor that a simmered stew simply can't match. It is a celebration of seasonal produce that brings a taste of the French countryside to your table with minimal effort.
I love serving this dish as a light main course alongside a crusty baguette and a creamy dollop of goat cheese, but it also shines as a vibrant side to grilled chicken or fish. The beauty of this recipe lies in its simplicity and the final aromatic flourish of fresh basil and a bright squeeze of lemon. Whether you are meal prepping for the week or looking for a stress-free dinner solution, this roasted vegetable medley is a healthy, gluten-free, and vegan-friendly option that tastes even better as the flavors meld overnight.
Ingredients
- Eggplant, cut into 1-inch cubes:1 lb
- Zucchini, sliced into half-moons:2 medium
- Yellow squash, sliced into half-moons:1 medium
- Red bell pepper, chopped into 1-inch pieces:1 large
- Yellow bell pepper, chopped into 1-inch pieces:1 large
- Red onion, cut into wedges:1 medium
- Cherry tomatoes:1 cup
- Garlic, minced:4 cloves
- Extra-virgin olive oil:1/4 cup
- Herbes de Provence:1 tbsp
- Kosher salt:1 tsp
- Black pepper:1/2 tsp
- Fresh basil leaves, torn:1/4 cup
- Lemon juice:1 tbsp
Instructions
-
Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
-
Place the cubed eggplant, zucchini, yellow squash, bell peppers, and red onion on the baking sheet.
-
In a small bowl, whisk together the olive oil, minced garlic, herbes de Provence, salt, and pepper.
-
Drizzle the oil mixture over the vegetables and toss thoroughly with your hands or a spatula to ensure every piece is evenly coated. Spread the vegetables out into a single layer.
-
Roast for 20 minutes. Remove the pan from the oven, add the cherry tomatoes, and give the vegetables a gentle toss.
-
Return the pan to the oven and roast for another 15 minutes, or until the vegetables are tender and charred around the edges.
-
Remove from the oven and immediately drizzle with lemon juice. Garnish with fresh torn basil leaves before serving warm or at room temperature.
Tips & Notes
- Try to cut the vegetables into similar sizes so they roast at the same rate; eggplant takes the longest, so don't cut those pieces too large.
- Don't overcrowd the pan. If the vegetables are piled on top of each other, they will steam instead of roast. Use two pans if necessary.
- Leftovers are incredible the next morning topped with a fried egg.
