This Oven Baked Ratatouille is simple, healthy and will seriously impress anyone you serve it to. There is something magical about the combination of fresh veggies bubbling away in your oven. So good.
Spoon the tomato sauce in a baking dish or pan and combine the garlic, onion, 1 tbs olive oil. Season with salt and pepper and smooth out.
Cut the edges from the veggies and using a mandolin (and safety skills) slice the veggies into thin rounds.
Artfully arrange the veggies, slightly overlapping one another in a pattern in your prepared pan starting at the outer edges and working your way in. (Pro tip! I used an upside down spoon, leaning against the edge of the pan, to prop everything into to place. Made those last few layers super easy to snuggle in).
Drizzle remaining olive oil over top. Season with salt, pepper and thyme. Cover the dish with parchment paper or aluminum foil and bake 45 to 50 minutes, until tomato sauce is bubbling around the edges.
