Roasted Ratatouille with Basil Aioli

Eggplant, tomatoes, bell peppers and zucchini are the stars of the Provençal summer garden and are featured in the famous vegetable stew, ratatouille. Here, the vegetables are roasted instead of stewed, which intensifies their flavor. The crowning touch is a basil-garlic topping called aioli.

Comments on this Recipe

I am confused. I thought that olive oil should not be heated above 350 degrees, at least for frying. Please explain. Thank you.

Absolutely scrumptious!!!!!

I've been making this for Thanksgiving for years and it is always a big hit. Yum!
