Harissa roasted cauliflower couscous is a spicy mix of grains that’s a great vegan main. Slicing the cauliflower maximizes its surface area for browning.
It’s no secret that I am completely obsessed with pesto.
That perfect mix of herbs, cheese and nuts is so much more than a sauce for pasta. I use this magical green paste as an easy flavor booster for eggs and grains and even a garnish for tomato soup.
I always make my pesto from scratch because I find that the jarred version has an almost cooked flavor. It’s just not the same without fresh herbs.
Looking for another option for a sauce/marinade that can be ready-to-use but purchased from grocery, harissa has become my thing lately.
That distinctly spicy red pepper paste often found in Moroccan food is the ultimate shortcut to add a kick of flavor with just a spoonful.
Much like my strategy with pesto, I add harissa to baked egg cups with sweet potatoes, peppers and zucchini.
And now I’ve started using harissa as a marinade for roasted vegetables.
When I first made this harissa roasted cauliflower couscous, I actually had the Super Bowl on the brain.
That probably makes no sense. Let me explain.
I was experimenting with making a vegan option for spicy wings, but once the cauliflower came out of the oven I realized it was better suited to a bowl of grains rather than dipping.
How To Make Harissa Roasted Cauliflower Couscous
To start, I trim the core of a head of cauliflower and then cut it into 1/2-inch thick slices.
The reason for flat pieces instead of florets is that more of the cauliflower has contact with the pan, so it maximizes the surface area for browning.
I add cumin, salt and pepper to the harissa and rub it all over the cauliflower before arranging it on a sheet pan.
While the cauliflower roasts, I make the couscous.
Those grains are simple and plain on their own and need something to jazz them up.
I puree a mixture of cilantro, parsley, chives, lemon juice and olive oil in the food processor and stir that into the couscous.
Once the cauliflower is ready, I fold it into the herby couscous and add chopped parsley and cilantro and minced chives.
Harissa roasted cauliflower couscous is a great vegan main. With the leftovers, I do my usual strategy to make the most of what I have by adding a few handfuls of arugula to create a grain salad.
