There is nothing quite like the smell of Mediterranean herbs and sweet, caramelizing vegetables wafting from the oven on a chilly evening. Tonight, I wanted something deeply comforting but packed with fresh flavor, so I recreated one of my absolute favorite Barefoot Contessa classics right in my own kitchen Ina Garten’s Roasted Ratatouille with Creamy Parmesan Polenta.

By roasting the zucchini, eggplant, and peppers at a high heat, they get those perfectly charred, sweet edges that melt right into a rich, velvety bed of cheesy polenta. It feels like an elegant, restaurant-quality meal, but it comes together beautifully using simple sheet pans.

What To Eat With This Roasted Ratatouille Polenta

Since this dish is rich and comforting, pair it with bright, textured sides a crisp arugula salad with a tangy lemon vinaigrette perfectly cuts through the buttery, cheesy polenta. Add a loaf of warm, crusty artisan bread to scoop up the caramelized tomato juices. For added protein, serve it alongside grilled chicken, pan-seared garlic shrimp, or savory Italian sausage. Finally, pour a glass of medium-bodied red wine like Chianti to complement the roasted Mediterranean flavors.

How to Store and Reheat Leftovers

How to Store

Separate Containers: Always store the ratatouille and polenta in separate airtight containers to prevent sogginess [delishknowledge.com].
Cool Completely: Let both components cool to room temperature before sealing to avoid texture-ruining condensation.
Refrigerate: Keep in the fridge for up to 4 to 5 days. The ratatouille actually tastes better the next day.
Freeze (Veggies Only): Freeze the ratatouille for up to 3 months. Do not freeze the polenta, as it becomes watery and grainy when thawed.

How to Reheat

The Ratatouille: Warm in a saucepan over medium-low heat for 5 minutes, stirring gently to keep the veggies intact. Alternatively, microwave in 30-second bursts.
The Polenta: Polenta hardens as it chills. Reheat on the stovetop over low heat, vigorously whisking in a splash of milk or chicken stock to restore its creamy texture.
The Crispy Alternative: Slice the cold, solidified polenta into blocks and pan-fry them in olive oil for 4 minutes per side until crispy, then top with the hot ratatouille.

Frequently Asked Questions

Can I make this ahead of time?
Yes. The ratatouille actually tastes better the next day as the flavors marinate. You can roast the vegetables a day in advance and reheat them gently before serving. However, the polenta is best made fresh, as it firms up significantly once cooled.

Is this dish gluten-free?
Yes! This recipe is naturally gluten-free. Polenta is made from cornmeal, and the ratatouille is purely vegetables and herbs. Just ensure your cornmeal is certified gluten-free to avoid cross-contamination.

Can I use quick-cooking polenta instead?
In a pinch, yes. However, Ina specifically recommends stone-ground cornmeal (like Bob’s Red Mill) for that signature texture. Quick-cooking polenta will be much smoother and less substantial, missing the “rustic” feel of the original dish.
