The perfect back to school sheet pan dinner!

Inspired by the flavors of ratatouille—you know, the featured French vegetable dish in the Pixar classic!—this dish consists of end-of-summer vegetables roasted melt-in-your-mouth tender and perfectly paired with roasted chicken—all in one pan. And the best part? The cooking time works beautifully for this sheet pan chicken recipe; just set your timer once and your chicken thighs and veggies will both be roasted to perfection, every single time. Trust me: you’ll be hooked!

Pro tips for the best ratatouille-inspired sheet pan chicken dinner

  • Make sure you slice the veggies thinly! This way, the veggies will roast evenly and turn meltingly tender in the oven. If you don’t have a sharp knife (or need to bone up on your knife skills), use a mandolin slicer or the slicing blade on your food processor to help you out!
  • Season each layer! To make sure the ratatouille vegetables are well-seasoned, make sure to sprinkle Magic Mushroom Powder (or salt + pepper) on each layer of veggie slices. No one likes bland veggies.
  • Don’t skimp on the extra virgin olive oil! You only need a thin layer of oil on the pan itself, but I like to drizzle about 3 tablespoons of extra virgin olive oil atop the vegetables before roasting. This extra oil helps with the flavor and proper roasting of the veggies without making ’em too greasy.

Meal prep tips

Ingredients

The raw ingredients that are prepped and measured out to make sheet pan chicken and veggies, inspired by ratatouille.
  • Bone-in chicken thighs: I love bone-in, skin-on chicken thighs because you can just season and toss them on the sheet pan without cutting them into bite-size pieces. I don’t recommend substituting boneless and skinless chicken thighs or chicken breasts (bone-in or boneless and skinless) because the veggies will still take about 45 minutes in the oven to get meltingly tender. If you decide to go against my advice, you’ll have remove the boneless chicken thighs or breasts from the sheet pan as soon as they’re cooked through (about 20 minutes) and continue roasting the veggies in the oven until they’re done. (Extra steps are a pain in the butt, so just do what I tell you, people!)
  • Magic Mushroom Powder Seasoning: My OG umami-seasoning blend really takes this recipe over the top and makes the chicken and veggies super flavorful without any extra work. (Psst! Magic Mushroom Powder is now available from Amazon and iHerb!) No MMP? I’ve tested this recipe with just Diamond Crystal kosher salt and freshly ground black pepper for seasoning and this sheet pan dinner still comes out great! [But if you use a different, finer grain salt (e.g., Morton’s kosher salt), remember to decrease the amount of salt you use.]
  • Eggplant: Just about any type of eggplant will work, but try not to use a large Italian one because they contain a lot of seeds. Slice the eggplant crosswise into thin slices that are a little less than ¼-inch thick and make sure they’re the bottom-most layer in your vegetable stack so they’ll be sure to cook through.
  • Tomatoes: Use Roma tomatoes or another meaty tomato. Don’t wanna slice tomatoes? Just toss on some cherry tomatoes instead! Or leave them out if you don’t like tomatoes.
  • Summer squash and zucchini: Eat the rainbow—use one of each so your roasted veggies are more colorful! Or just use one if you’re feeling lazy / boring.
  • Orange, yellow, or red bell pepper: Choose any color bell pepper you want!
  • Onion: Any color onion will work, so I normally choose whatever half onion is languishing in my fridge (usually a yellow, white, or red onion). The key is to slice the onion super thin so they melt into the roasted vegetables.
  • Garlic: I thinly slice the cloves instead of mincing them so the garlic doesn’t burn.
  • Fresh herbs: I season the ratatouille with minced fresh basil and thyme and then top the finished roasted vegetables with minced fresh Italian parsley for a pop of green and freshness. If you want to use dried basil and thyme, make sure to decrease the amount as stated in the recipe card below.
  • Extra virgin olive oil: Use EVOO for coating the baking sheet and drizzling over the ratatouille vegetables.
  • Aged balsamic vinegar: For a pop of sweetness and tang, I drizzle aged balsamic vinegar on top of the roasted veggies at the end. Feel free to substitute fresh lemon juice, sherry vinegar, or your favorite acid.

If you have any leftover sheet pan chicken and veggies, store them in an airtight container in the refrigerator for up to 4 days. I usually toss my leftovers into an Anyday glass container and pop them in the microwave when I want to reheat and eat!
