This Easy Sheet Pan Ratatouille is the perfect way to turn all of those late-summer vegetables into an easy dinner or side dish. What I love about this Sheet Pan Dinner is that you can roast everything together and then decide how you want to serve it.

Zucchini, eggplant, bell peppers, tomatoes, and onion get caramelized in the oven with plenty of garlic and Italian seasoning. Then comes the best part: tear creamy mozzarella over the warm vegetables and finish everything with fresh basil, balsamic glaze and Parmesan.

I've been making this when summer produce is at its best, and it's such an easy recipe to switch up. Serve it as a vegetable side dish or make it a meal by adding chicken sausage, pasta, or gnocchi.

If you like this dish, you should try my Italian Zucchini and Sausage, Zucchini and Eggplant Lasagna (No Noodle) or my Italian Meatloaf Mini Muffins.

Why You Will Love This Dinner

Easy Cooking

Everything roasts together on one sheet pan, which means minimal prep and cleanup.

Packed with Summer Vegetables

Zucchini, eggplant, tomatoes, bell peppers, and onions make this an easy way to use a bunch of seasonal produce in one recipe.

Versatile Meal

Eat the roasted ratatouille on its own, serve it as a side, or add your favorite protein or carb to turn it into a complete dinner.

Ingredients

Zucchini

Zucchini becomes tender and slightly caramelized when roasted at high heat.

Eggplant

One of the classic vegetables in ratatouille. Roasting gives it a soft, almost creamy center with caramelized edges.

Red Bell Pepper

Adds natural sweetness and color.

Cherry Tomatoes

As the tomatoes roast, they burst and release their juices, creating an easy sauce for the vegetables.

Yellow Onion

Becomes sweet and caramelized in the oven.

Garlic

Fresh garlic adds plenty of savory flavor.

Olive Oil

Helps the vegetables caramelize instead of simply steaming.

Italian Seasoning

An easy way to add plenty of herb flavor without needing several individual spices.

Basil

Use dried basil before roasting or finish the vegetables with fresh basil. I especially love fresh basil when it's in season.

Mozzarella

fresh mozzarella takes simple roasted vegetables to the next level.

Parmesan

Adds salty, savory flavor to finish the dish.

Substitutions and Variations

Make It a Meal

Add sliced chicken sausage to the sheet pan before roasting for an easy protein option.

Add Pasta

Toss the finished ratatouille with your favorite cooked pasta and a splash of pasta water.

Add Gnocchi

Add shelf-stable gnocchi directly to the sheet pan before roasting for a heartier one-pan meal.

Make It Fresh

Don't skip the fresh basil, mozzarella, and Parmesan. They're an easy way to make roasted vegetables feel like a complete summer dinner.

Make It Dairy-Free

Skip the mozzarella and Parmesan and finish with extra fresh basil and a drizzle of good olive oil.

Use What You Have

Yellow squash, different colored bell peppers, or extra tomatoes are all easy swaps.

How to make this sheet pan Ratatouille

1. Prepare the Vegetables

Add chopped zucchini, eggplant, bell pepper, cherry tomatoes, sliced onion, and minced garlic to a large sheet pan.

2. Season

Drizzle everything with olive oil.

Sprinkle with kosher salt, Italian seasoning, dried basil, black pepper, and red pepper flakes if using.

Toss until the vegetables are evenly coated.

Spread everything into an even layer.

3. Roast

Roast for 25–30 minutes, tossing halfway through.

The vegetables are ready when they're tender and caramelized and the cherry tomatoes have started to burst.

4. Add the Mozarella

Remove the sheet pan from the oven and tear the mozzarella over the warm vegetables.

Sprinkle with Parmesan and let everything sit for a minute.

6. Finish

Top with plenty of fresh basil and extra Parmesan before serving.

Tips and Notes

• Don't overcrowd your sheet pan. Giving the vegetables room helps them roast and caramelize rather than steam.
• Cut the zucchini and eggplant into similarly sized pieces so they cook evenly.
• High heat is key! 425°F helps give the vegetables those delicious caramelized edges.
• If your sheet pan is too crowded, divide the vegetables between two pans.
• Add fresh basil after roasting so it stays bright and flavorful.
• Let the burrata sit on the hot vegetables for a minute before breaking it apart.

Storage and Reheating Instructions

For best results, store the roasted vegetables separately from the burrata in an airtight container in the refrigerator for up to 4 days.

Reheating

Reheat the vegetables in a 400°F oven or air fryer until warmed through and slightly crisp around the edges. You can also microwave individual portions.

Add fresh burrata, basil, and Parmesan after reheating rather than storing everything mixed together. It makes leftovers taste much fresher.
