Delicious French-inspired ratatouille features melty summer vegetables like zucchini, eggplant, tomatoes, and red bell peppers! Made in just one dish in the oven!
Start by dicing the zucchini, eggplant, red bell pepper, and onion into 1-inch cubes. Transfer the diced veggies to a 9x7-inch baking dish. Drizzle with the olive oil, add the salt, and stir to coat. Bake for 30 minutes.
In the meantime, dice the tomatoes into 1-inch cubes and transfer them to a bowl or deep plate. Add the balsamic vinegar, sugar, minced garlic, and thyme. Stir to coat, and let the tomatoes marinate for 25-30 minutes.
Next, remove the baking dish from the oven and add the marinated tomatoes (as well as the juice). Stir to combine the tomatoes with the other veggies.
Place the baking dish back into the oven and lower the temperature to 200°F (100°C). Bake for about 2 hours, stirring once halfway through baking.
Remove from heat, taste, and adjust saltiness if needed. Add the chopped basil and stir to coat.
Serve warm with rice, quinoa, or noodles! This ratatouille will keep for up to 4 days in the refrigerator.
Notes
I recommend preparing ratatouille one day ahead, as it tastes better the next day.
