oven-roasted cauliflower head recipe for a vegetarian one-dish dinner

ed. note: This recipe is from our interview with Chef Seamus Mullen. Seamus served this whole roasted cauliflower as one of the family-style dishes at a dinner party he hosted in Santa Monica, California earlier this year. I had tried making whole-roasted cauliflower before, and the results had always been a little lackluster… and mushy. Seamus’s version convinced me that with just a little technique (ie blanching and then roasting at a high heat) plus a flavor-packed salsa verde, a head of cauliflower can be transformed into a super satisfying vegetarian dinner. For a party, serve with his lamb meatballs and a zesty radish, fennel, & grapefruit salad.

A whole head of cauliflower roasted until caramelized and crispy in the oven is its own sort of magic.

When prepared the right way, cauliflower becomes a glorious melt-in-your-mouth feast that bears little resemblance to its raw state.

Seamus’s was the best version I’ve ever had, so I’m very excited he shared the recipe with us. It’s the perfect one-dish vegetarian dinner for when you want to eat clean without sacrificing an ounce of flavor. Make extra of the salsa verde, since it’s a perfect accompaniment to fish, meat, or to dress raw veg and salads.

    The ingredients list says “2 tablespoons cup white balsamic vinegar” – can you clarify the measurements?
