Sheet Pan Ratatouille Recipes

Steps:

• Heat oven to 425 degrees, and arrange two racks in the top and bottom thirds.
• On one rimmed 13-by-17-inch sheet pan, toss together onion slices, zucchini, 1/4 cup oil, 3 thyme springs, 2 rosemary sprigs, 3 garlic cloves and 1/2 teaspoon salt.
• On a second rimmed baking sheet, toss together eggplant, red peppers, 1/4 cup oil, 3 thyme sprigs, 2 rosemary sprig, 3 garlic cloves and 3/4 teaspoon salt.
• Place one tray on the top rack, and a second on the bottom rack of the oven. Roast both for 40 minutes, stirring vegetables two or three times.
• Add tomatoes to the baking sheet with eggplant and peppers, then continue to roast until the tomatoes burst and the zucchini turn deeply golden brown, another 20 to 25 minutes. The vegetables will become very caramelized, and that's a good thing, particularly with the zucchini and onions.
• Transfer zucchini and onions to the baking sheet with eggplant, mix well, and spread in an even layer (it will just fit). Drizzle vegetables with another 1 tablespoon oil, then sprinkle goat cheese and olives over the top. Roast until goat cheese is soft and warmed through, 5 to 10 minutes.
• Transfer vegetables to a serving platter, drizzle with a little more oil and squeeze juice from the one of the lemon wedges over the top. Garnish with basil leaves. Serve hot or warm, with more lemon wedges on the side.

Steps:

• Preheat the oven to 425 degrees F (220 degrees C).
• Arrange eggplant, zucchini, bell pepper, and onion on a greased or foil-lined baking sheet. Spray vegetables with cooking spray. Season with 1/8 teaspoon black pepper.
• Roast in the preheated oven, stirring and rotating pan once during cooking, until vegetables are lightly browned and tender, about 40 minutes.
• Meanwhile, stir together tomato, oil, parsley, and 1/8 teaspoon each salt and black pepper in a large bowl. Add cooked vegetables and remaining 1/4 teaspoon salt. Toss to combine.

Steps:

• Preheat oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper.
• Place eggplant, zucchinis, tomatoes, onion, bell pepper, and garlic in a single layer on the prepared baking sheet. Drizzle with olive oil, rosemary, salt, and pepper; toss vegetables until well coated.
• Roast in the preheated oven until slightly tender; about 20 minutes. Mix and roast for another 12 minutes. Reduce heat to 300 degrees F (150 degrees C) and cook until vegetables begin to caramelize; about 10 minutes. Drizzle with balsamic vinegar.

Steps:

• Heat oven to 350 degrees.
• Prepare the vegetables: Smash and peel 3 garlic cloves, reserving the 4th. Halve onions through their roots, and slice halves into 1/4-inch-thick pieces. Slice zucchini into 1/4-inch-thick rounds. Cut eggplant into 1-inch cubes or spears. Seed peppers, and cut them into 1/4-inch-thick strips.
• Spread each vegetable on a separate rimmed baking sheet (use extra sheets as necessary). Add the 3 cloves of smashed garlic to the onion pan. Add 1 sprig rosemary and 2 sprigs thyme to each of the pepper, eggplant and zucchini pans. Sprinkle salt lightly over vegetables. Drizzle 3 tablespoons olive oil on each of the pans.
• Place all the pans in the oven (or work in batches if they don't fit at once). Cook until vegetables are very tender and lightly browned at the edges. This will take about 35 to 40 minutes for the peppers (their skins should shrivel), 40 to 45 minutes for the eggplant and zucchini (the eggplant should crisp slightly and the zucchini should be well cooked, so let them go 3 to 5 minutes longer than you normally might), and 60 to 65 minutes for the onions. Don't worry about the vegetables being pretty; they will meld into the ratatouille. Shake or stir the pans every 15 to 20 minutes or so, especially the onions.
• In the meantime, prepare the tomatoes: Bring a large pot of water to a boil. Add tomatoes and blanch until the skins split, about 10 seconds. Use a slotted spoon to quickly transfer the tomatoes to a bowl filled with ice water.
• Using a paring knife, peel the cooled tomatoes (the skins should slip right off). Halve tomatoes across their equators. Set a sieve over a bowl. Working over the bowl, use your fingers to seed the tomatoes, letting the seeds catch in the sieve and the juice run into the bowl. Discard seeds but save juices. Dice tomatoes and add to the reserved juices in bowl.
• Finely grate or mince remaining garlic clove. Add garlic to tomatoes along with bay leaves and a large pinch of salt. Set aside.
• Once vegetables are done cooking, combine them on one baking sheet or a large shallow baking dish and add ingredients from tomato bowl. Toss well. Vegetables will be stacked, and that's O.K. Cover generously with olive oil, using remaining ¼ cup oil or more, and sprinkle with salt. Everything should have a good coat of oil, but should not be drowning in it. Cook at least 1 hour, stirring every 15 to 20 minutes, until vegetables are very tender and imbued with juices and oil. Add salt and pepper to taste, then serve warm, or let cool.
