Easy Sheet Pan Ratatouille

A sheet pan supper, by way of Provence.

A traditional, easy ratatouille recipe baked on a sheet pan for a simple, summery French vegetable side.

The late-summer produce bonanza of yellow squash, zucchini, eggplant, and tomatoes cries out to be cooked into a big batch of something tasty. Ratatouille, a rustic summer stew from the Provençal region of southern France, obliges.

Traditionally, ratatouille (pronouced rat-tat-OOO-ee) gets simmered and stirred over a stove. But this ratatouille lets the a sheet pan do the work while you enjoy a cold drink anywhere that is not a hot kitchen. The oven cooks down the vegetables until the eggplant and squash are soft and silky and the tomatoes burst with juice.

What Is in a Traditional Ratatouille Recipe?

Traditional ratatouille consists of a seasonal stew of late summer vegetables. Think tomatoes, zucchini, yellow squash, onion, tomatoes, and herbs.

Originally served as a rustic dish in the Provençal region of France, ratatouille has become popular well beyond these local borders thanks to its great flavor, heartiness — and ability to use a lot of seasonal vegetables at once.

Cuisine: French

Keywords:: easy ratatouille recipe, eggplant, French food, ratatouille, sheet pan, summer, vegan, vegetarian, zucchini

Servings: 4 people, as a side dish

Ingredients

• 1 smallish eggplant, peeled
• 1 bell pepper
• 1/2 large yellow onion
• 2 small zucchini or yellow squash, or 1 large
• 1 pint grape tomatoes
• 3 large cloves fresh garlic, peeled and roughly chopped
• 1/2 teaspoon fresh thyme leaves, or 1/2 teaspoon dried
• 1/8 cup extra-virgin olive oil
• 3/4 teaspoon Kosher salt, plus more to taste
• 12 turns freshly-ground pepper (about 1/2 teaspoon)
• 1 small handful fresh torn basil or parsley leaves, to garnish (optional)

Instructions

• Preheat oven to 375°F and line a half-sheet pan with parchment or lightly coat with olive oil.
• Cut the eggplant, pepper, onion, and zucchini into a 1/2" dice and spread on the sheet pan. Add the tomatoes, garlic, thyme, olive oil, salt, and pepper and toss to coat and fully stir.

  Note: Eggplant recipes often call for salting the eggplant first to draw out some of the moisture. That is not necessary here; the moisture serves to help make the final dish nice and saucy.
• Bake, uncovered, for 45 minutes to one hour, stirring occasionally, until the vegetables are very soft and the tomatoes turn jammy.
• Spoon the vegetables into a large bowl and stir to break up the tomatoes to make the dish a little saucy. Taste for seasoning (I usually add a pinch more salt) and serve, garnished with torn fresh basil or parsley, if desired.
