Whole roasted cauliflower has, for me anyway, transcended its fad stage, remaining a go-to for an impressive weeknight dinner. Its relatively bland flavor is a perfect canvas for strong, bold additions, like this Caesar salad dressing–inspired marinade. Made with Worcestershire sauce, Dijon mustard, and garlic, it hits all the flavor notes you want in a Caesar salad, but without the lettuce.
In a liquid measuring cup, whisk together the olive oil, vinegar, Worcestershire, parmesan, mustard, garlic, anchovies, and salt and pepper to taste.
Place the cauliflower head upside down on a cutting board and use a paring knife to make an “x” through the full length of the core.
Transfer the cauliflower head to a large bowl and pour half the dressing over it.
Turn the cauliflower head to coat it in the dressing, then let it rest, stem-side up, in the dressing for at least 10 minutes and up to 30 minutes to allow the dressing to seep into all its nooks and crannies.
Transfer the cauliflower head, stem-side down, to the air fryer and cook at 340°F for 25 minutes.
Drizzle the remaining dressing over the cauliflower and cook at 400°F until the top of the cauliflower is golden brown and the core is tender, about 5 minutes more.
Remove the basket from the air fryer and transfer the cauliflower to a large plate.
Sprinkle with the parsley, if you like, and serve hot.
Notes / Tips / Wine Advice:
Go Basic:If you want to cook a plain roasted whole cauliflower, simply rub it with the olive oil, season all over with salt and pepper, and cook at 340°F for 30 minutes.
