This Whole Roasted Cauliflower with Rustic Herb Sauce brings cozy holiday vibes to your table—no turkey required. A head of cauliflower roasted until golden, served over creamy mashed potatoes and drizzled with a garlicky, rosemary-sage sauce topped with tangy cranberries, toasted pine nuts, and fresh herbs.
Preheat oven to 450˚F(230˚C). Line a baking sheet with parchment paper.
Slice off most of the bottom stalk of the cauliflower head, leaving just enough to make sure the core stays intact.
Bring vegetable broth to a boil in a large pot. Once boiling, place cauliflower inside. Cover and reduce heat to simmer. Let cook for 4 minutes.
In a bowl, mix together the Rustic Herb Sauce ingredients.
Remove cauliflower and place on wire rack on baking sheet to dry. Place the cubed potatoes in the same broth/pot and cook for 10-15 minutes or until fork tender.
Dry cauliflower off with a towel. Let cool for 10 minutes. After 10 minutes, check the cauliflower to see if any moisture remains and dry again, if so.
Brush half the Rustic Herb Marinade across the whole cauliflower with a pasty brush. Place in oven for 45 minutes. Last 5 minutes, broil to char the top of cauliflower slightly.
When potatoes are done cooking, drain and add in butter, salt and pepper. Carefully use a hand mixer to blend together while pouring in the cashew milk. Alternatively, you can use a potato masher and mash the potatoes.
Spread mashed potatoes on bottom of a serving dish. Add cauliflower head on top. And drizzle remaining Rustic Herb Sauce, sprinkle cranberries, pine nuts, leftover herbs and serve.
Notes
Don’t skip drying the cauliflower: Patting it dry after boiling helps it roast instead of steam—giving you that beautiful golden crust on the outside while staying tender inside.
Use the same broth twice: Boil the cauliflower first, then cook your potatoes in the same flavorful broth to add an extra layer of herby goodness (and save a dish!).
Make it ahead: You can roast the cauliflower earlier in the day and reheat it at 350°F for 10–15 minutes before serving. Just whisk the herb sauce fresh for the best flavor.
Level up the garnish: A sprinkle of dried cranberries, toasted pine nuts, and a few fresh herb leaves turns this dish into a total showstopper—perfect for your holiday table photos.
