📝 Variations & Substitutions

🔪 Recipe Instructions
Heat the oven to 400°F. In a large bowl, toss the cauliflower with 2 tablespoons olive oil, 1 teaspoon salt and ¼ teaspoon pepper. Spread the cauliflower on a baking sheet in a single layer. Roast until golden, 30 to 40 minutes. Let cool for 10 minutes.
In a small bowl, whisk together the vinegar with the remaining salt and pepper, and then whisk in the remaining oil.
In a salad bowl, toss the arugula, cheese, nuts and warm cauliflower. Pour the vinaigrette over the salad and toss until well combined.
👩🏼🍳 Expert Tips
- Storage: Place in an airtight container in the refrigerator for up to 3 days.
- Make ahead: The cauliflower can be roasted one day ahead of time. Just slip the roasted florets back into a preheated 350 degree F. oven for 15 minutes right before serving. Assemble and dress the salad.
- How to serve: This salad is best served warm but it can also be served chilled.
- Garnish with quick pickled red onions for extra crunch and tanginess.
- For a holiday table: Pair it with any holiday side dish, like vegetarian mushroom stuffing or red skin mashed potatoes. And for a show-stopping holiday dessert, try my caramel nut tart!
💬 Frequently Asked Questions
Make sure your cauliflower is not overcrowded on the baking sheet when roasting. In addition, using ample olive oil (or your preferred fat) and roasting at a higher heat will prevent mushy cauliflower.
The best practice is to give your cauliflower florets a good rinse or soak after chopping. Be sure to pat dry with a paper towel or dish towel before roasting to avoid excess moisture.
Roasted cauliflower is easy to reheat. Just slip the roasted florets back into a preheated 350 degree F. oven for 15-20 minutes (until nice and crisp) right before serving.
