Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 425 degrees.
Drain and rinse chickpeas; pat very dry with paper towels. Halve, peel, and cut half the onion (whole onion for 4) into 1⁄2-inch-thick wedges.
Toss chickpeas and onion on a baking sheet with a drizzle of oil, half the Italian Seasoning (all for 4), salt, and pepper.
Roast on top rack until chickpeas are golden and tender and onion is caramelized, 18-20 minutes. (You’ll add more to the sheet after 11 minutes.)
