Ingredients

This rustic preparation celebrates the natural sweetness and textures of peak-season produce.

• 1 medium eggplant, unpeeled, cut into 1-inch cubes
• 1-2 small zucchini, cut into 1-inch cubes
• 1 red bell pepper, cut into 1-inch cubes
• 1 large Spanish onion or 1 large Vidalia onion, cut into large wedges (about 8-10 pieces)
• 2 dozen cherry tomatoes
• 3-4 garlic cloves, whole (optional)
• Salt and freshly ground black pepper, to taste
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• 2 tablespoons olive oil
• 2 ounces goat cheese (Chevre), crumbled (optional, for serving)
• 8-10 fresh basil leaves, chopped (for finishing)

Equipment Needed

• Large rimmed baking sheet
• Aluminum foil
• Cooking spray (optional, for lining the pan)
• Large bowl (for tossing vegetables)
• Tongs or large spoon

Instructions

The beauty of this roasted ratatouille lies in its simplicity. The oven does most of the heavy lifting, coaxing out the inherent sweetness of the vegetables.

1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Line a large, rimmed baking sheet with aluminum foil. For easier cleanup, you can spray the foil with cooking spray, though it’s not strictly necessary.
2. Chop the Vegetables: Prepare your vegetables as directed in the ingredient list: cut the eggplant into 1-inch cubes, ensuring you leave the skin on for texture and nutrients. Cut the zucchini into similar 1-inch cubes. Cut the red pepper into 1-inch pieces, discarding the seeds and membrane. Cut the onion into large wedges, aiming for about 8-10 substantial pieces per onion. Leave the cherry tomatoes whole. If you are using garlic, leave the garlic cloves whole as well – they will become wonderfully sweet and mellow when roasted.
3. Combine and Season: Place all the prepared vegetables – eggplant, zucchini, red pepper, onion wedges, cherry tomatoes, and optional garlic cloves – into a large bowl.
4. Dress the Vegetables: Sprinkle the vegetables generously with salt and freshly ground black pepper to your personal preference. Add the dried oregano and dried basil. Drizzle the 2 tablespoons of olive oil evenly over the vegetables.
5. Toss to Coat: Using your hands or a large spoon, gently toss the vegetables to ensure they are evenly coated with the seasonings and olive oil. This coating is crucial for achieving that beautiful caramelization.
6. Arrange on Baking Sheet: Spread the seasoned vegetables in a single layer on the prepared baking sheet. It’s important they are not overcrowded, as this will steam them rather than roast them, preventing the development of those desirable crispy edges. If necessary, use two baking sheets.
7. Roast and Turn: Place the baking sheet in the preheated oven. Bake at 350°F (175°C) for about 1 hour. During the roasting process, it’s important to turn the vegetables every 15 minutes. This ensures even cooking and browning on all sides. You’ll notice the vegetables softening, the edges beginning to brown, and the tomatoes starting to burst and sweeten.
8. Finish and Serve: Once the vegetables are tender and nicely caramelized, remove the baking sheet from the oven. While the ratatouille is still warm, gently toss it with the chopped fresh basil leaves. If you are using, crumble the 2 ounces of goat cheese over the warm vegetables. The residual heat will slightly soften the cheese, creating a lovely creamy counterpoint to the roasted vegetables.

Expert Tips & Tricks

For a truly exceptional ratatouille, consider these chef-inspired touches:

• Uniformity is Key: When cutting your vegetables, try to keep the pieces as uniform in size as possible. This ensures they all cook at the same rate, preventing some from becoming mushy while others remain undercooked.
• Don’t Crowd the Pan: This is perhaps the most critical tip for achieving roasted perfection. Overcrowding leads to steaming, not roasting. If your vegetables look like they’re piled too high, use a second baking sheet. The slight effort is worth the vastly superior texture and flavor.
• Embrace the Char: Don’t be afraid of a little charring on the edges of the vegetables. This is where much of the deep, rich flavor comes from. The natural sugars in the vegetables caramelize beautifully under the dry heat of the oven.
• Taste and Adjust: Always taste your seasonings before roasting. The salt and pepper are essential, but you can also adjust the herbs to your liking. Perhaps a pinch of red pepper flakes for a touch of heat?

Serving & Storage Suggestions

Roasted ratatouille is incredibly versatile. It’s delicious served warm as a side dish to grilled meats, fish, or poultry. It also shines as a vegetarian main course, perhaps served over a bed of quinoa or alongside crusty bread for soaking up the flavorful juices.

Leftovers are fantastic! Store them in an airtight container in the refrigerator for up to 3-4 days. The flavors often meld and deepen overnight, making it even more delicious the next day. To reheat, gently warm it in a skillet over medium-low heat, or briefly in the microwave. You can also serve it cold or at room temperature as a vibrant salad component. This dish does not freeze particularly well, as the texture of the vegetables can become watery upon thawing.

Variations & Substitutions

While this recipe is wonderful as is, feel free to experiment:

• Add More Color: Toss in some diced yellow squash or bell peppers of different colors (red, yellow, orange) for an even more vibrant presentation.
• Herbal Infusion: Experiment with other herbs like thyme, rosemary, or marjoram. Add them along with the oregano and basil before roasting for a more complex herbal profile.
• Spicy Kick: For those who enjoy a little heat, add a pinch of red pepper flakes along with the dried herbs.
• Tangy Twist: A tablespoon of balsamic vinegar drizzled over the vegetables before roasting can add a lovely sweet-tangy dimension.
• Vegan Cheese Alternative: If you prefer to keep this strictly vegan and omit the goat cheese, a sprinkle of nutritional yeast can add a cheesy umami note, or you can simply enjoy it unadorned.

FAQs

Q: Can I use different types of onions?
A: Absolutely! While Spanish or Vidalia onions offer a pleasant sweetness, yellow onions or even red onions can be used, though they might have a slightly stronger flavor.

Q: My vegetables aren’t browning. What could be wrong?
A: The most common reason for lack of browning is overcrowding the pan. Ensure your vegetables are in a single layer and have space to breathe. Also, make sure your oven is preheated to the correct temperature and has been at that temperature for at least 15-20 minutes.

Q: Can I add other vegetables to this ratatouille?
A: Yes, feel free to add other summer vegetables like eggplant, summer squash, or even fennel. Just ensure they are cut into similar sized pieces to cook evenly.

Q: How do I know when the vegetables are done?
A: The vegetables should be tender when pierced with a fork and have nicely caramelized edges. The cherry tomatoes will have softened and started to burst.

Q: Is it important to leave the eggplant skin on?
A: Leaving the skin on the eggplant adds texture and helps it hold its shape during roasting. It also contains nutrients. If you strongly dislike eggplant skin, you can peel it, but be aware the texture will be softer.
