This roasted ratatouille is an easier way to make ratatouille in the oven rather than on the stovetop.

Now is the time to make ratatouille, that in-between period when summer is winding down and fall is just around the corner. Although Labor Day is the unofficial end of summer we do technically have a couple more weeks left and I’m not in a rush to bid summer goodbye quite yet.
So these last days of summer and first days of fall, while tomatoes, zucchini, eggplant and peppers are still plentiful, I’ll be making roasted ratatouille.

How to make ratatouille in the oven:
You start with the usual tomatoes, peppers, eggplant and zucchini, but instead of cooking them on the stove-top you let the oven do all the work. Roasting the vegetables brings out their natural sweetness and intensifies their flavor.
Instead of traditional thyme and bay leaves I add harissa paste for a spicy North African twist; the red chili pepper and sun-dried tomato paste is bright, bold and a wonderful compliment to the roasted vegetables. The vegetables are coated with the spices and olive oil then spread out on a sheet pan to roast until tender.
What you end up with are vegetables that are softened and infused with lots of garlic, olive oil and spice. The eggplant is smooth and silky, the tomatoes sweet and juicy, the zucchini tender and creamy and the peppers soft and slightly charred at the edges.

How to serve:
You can serve ratatouille hot or cold and the flavors only improve with an overnight stint in the fridge. I like to serve mine with cauliflower couscous but you can also eat it by itself. The cauliflower couscous comes together in a flash and cooks right in the oven so it’s really quite easy to make. You just chop a head of cauliflower in the food processor, toss it with some oil and spices then spread it out onto a sheet pan and pop it in the oven alongside the vegetables until golden and nutty.
Hearty and healthy and filled with vegetables, this roasted ratatouille couscous comes together in less than an hour, making it a great weeknight option.
