Instructions

  1. Step 1: Preheat oven to 375°F. Heat 2 tbsp olive oil in a skillet over medium heat and add 1 small finely chopped onion with 6 whole garlic cloves. Sauté for 5 minutes until onions are translucent and garlic softens.
  2. Step 2: Remove garlic cloves from skillet and mash lightly, then mix with onions. Spread this mixture evenly at the bottom of a 9-inch round baking dish.
  3. Step 3: Arrange alternating slices of 1 medium zucchini, 1 medium eggplant, and 3 large roma tomatoes upright over the onion-garlic base in a spiral pattern.
  4. Step 4: Drizzle the remaining 2 tbsp olive oil over the layered vegetables. Season evenly with 1 1/2 tsp sea salt, 1 tsp black pepper, and 1 tsp dried thyme.
  5. Step 5: Cover the dish tightly with foil and bake for 35 minutes. Remove foil and bake for an additional 15 minutes until vegetables are tender and slightly caramelized.
  6. Step 6: Remove from oven and sprinkle 1/4 cup chopped fresh basil leaves over the top. Let rest for 5 minutes before serving.

How do I store leftover Oven-Baked Ratatouille with Roasted Garlic and Fresh Basil?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep zucchini from drying out.

Can I substitute ingredients in Oven-Baked Ratatouille with Roasted Garlic and Fresh Basil?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Oven-Baked Ratatouille with Roasted Garlic and Fresh Basil for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
