Beautiful spiraled Ratatouille is one of my favorite recipes to make in the summer to emphasize my garden’s seemingly endless bounty. But sometimes I want something a little quicker, easier, and substantial. Enter this sheet pan ratatouille. It takes classic ratatouille ingredients, adds some hearty sausage, and simple sheet pan prep. Yum!
Helpful Tips & Variations
- Any sausage works. Regular pork sausage links works great in this recipe but chicken sausage is also a great option. Just make sure they’re fully cooked.
- Use the veggies you have. Feel free to customize this sheet pan ratatouille by using the fresh veggies you have on hand, like grape tomatoes instead of cherry, other colors of bell peppers, etc.
- Cut everything into equal pieces. All the veggies should be cut into roughly the same size. This helps ensure even cooking. A mandolin is great for this.
- Make it vegetarian. For a vegetarian ratatouille, just omit the sausage. Feel free to replace it with tofu or add more veggies.

How To Make Sheet Pan Ratatouille Step by Step

- Gather the ingredients. Preheat the oven to 425 degrees F, then coat an extra large rimmed 18×13 baking sheet (or 2 smaller ones) with nonstick spray.
- Prep the vegetables. Using a mandolin or knife, slice 1 small Japanese eggplant, 1 small zucchini, 1 small yellow summer squash, 1 large orange bell pepper, and 1/2 red onion all 1/4-inch thick.

- Transfer to the baking sheet. Dump all the sliced veggies, 1 pint cherry tomatoes, and 4 fully cooked and cut smoked sausage links onto the prepared baking sheet.

- Make the seasoning. In a medium mixing bowl, whisk together 1/3 cup olive oil with 1 teaspoon dried Italian seasoning, 1/2 teaspoon each garlic powder and coarse salt, and 1/4 teaspoon each black pepper and lemon pepper. Drizzle over the vegetables and sausage.

- Roast. Transfer to the oven and roast for 25 minutes, until the vegetables are fork tender and the sausage is slightly charred.

Serving Suggestions
With the addition of the smoked sausage, this sheet pan ratatouille is a complete meal all on its own. You can just serve it hot from the oven as-is for a tasty, light and healthy summer dinner.
However, if you want a little more to your meal, crusty bread or focaccia is a great addition to this dinner. Ratatouille is also often served over creamy polenta or even pasta, though this sheet pan meal doesn’t have a sauce that you would normally have for the pasta. White rice, rice pilaf, cauliflower rice, and quinoa are all options, as well.
How to Store Leftovers
Allow leftover baked ratatouille to cool completely, then store in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave. I do not recommend freezing this dish.
