Ever wish dinner could be easy, colorful, and deeply flavorful without standing over a stove? Sheet Pan Ratatouille might just be your weeknight hero. Packed with vibrant summer vegetables and kissed with olive oil and herbs, it captures the spirit of Provence in the most effortless way.

This version ditches the traditional skillet sauté for a fuss-free oven roast, giving the veggies golden edges and caramelized depth. It’s rustic, it’s nourishing, and it slides straight from the oven to your table in one pan.

Preparation Phase & Tools to Use

For this Sheet Pan Ratatouille, a large rimmed sheet pan is essential. It allows the vegetables to spread in a single layer for even roasting and browning.

A sharp chef’s knife makes prepping the zucchini, bell peppers, onions, and tomatoes a breeze, ensuring clean, uniform slices for even cooking.

Use a cutting board that’s large enough to handle all your vegetable prep. Bonus if it’s non-slip!

A mixing bowl comes in handy for tossing your sliced veggies in olive oil, garlic, salt, and herbs.

Lastly, a wooden spoon or spatula is ideal for spreading the vegetables onto your pan and flipping them mid-roast for maximum color and texture.

Red Onion: Offers just the right hint of sharpness and turns gorgeously sweet in the oven.
Cherry Tomatoes: They burst and caramelize, adding juicy depth.

How To Make the Sheet Pan Ratatouille

Step 1: Prep the Vegetables

Slice the zucchini, squash, and bell peppers into ½-inch rounds and strips. Halve the cherry tomatoes and slice the red onion into thick wedges. Mince the garlic finely.

Step 2: Season Everything

In a large mixing bowl, toss all the vegetables with olive oil, minced garlic, salt, pepper, and herbs until well coated.

Step 3: Spread and Roast

Preheat your oven to 425°F (220°C). Spread the vegetables evenly over a parchment-lined rimmed sheet pan. Avoid overcrowding to promote caramelization.

Step 4: Flip Midway

After 15 minutes, give everything a gentle flip with a spatula. Roast another 10-15 minutes until the veggies are golden and tender.

Step 5: Serve Fresh or Store

Serve hot with crusty bread or cool and refrigerate for later use in wraps, pastas, or grain bowls.

Serving and Storing Sheet Pan Ratatouille

This dish is best served warm straight from the oven as a side or light main. Pair it with a slice of toasted sourdough, a soft polenta base, or simply enjoy it solo.

To store, allow the ratatouille to cool completely. Then refrigerate in an airtight container for up to 4 days. It also freezes beautifully for up to 2 months, making it a great meal-prep component. Reheat in the oven or on the stovetop to maintain the roasted texture.
