Cauliflower Steaks with Romesco Sauce Recipe FAQs
How do I select the best cauliflower for steaks?
Choose a firm, heavy head of cauliflower with tight, creamy-white florets and no dark spots. Freshness is key—avoid any with limp leaves or soft stems to ensure your steaks stay intact during grilling.
Can I store leftover cauliflower steaks and Romesco sauce?
Absolutely! Store leftover cauliflower steaks in an airtight container in the refrigerator for up to 3 days. Keep the Romesco sauce in a separate airtight jar; it lasts about 4 to 5 days refrigerated and tastes even better after letting the flavors meld overnight.
Is it possible to freeze cauliflower steaks and the sauce?
Yes! To freeze, first lay the cooked cauliflower steaks on a baking sheet in a single layer and freeze for 1 to 2 hours until firm. Then transfer them to a freezer-safe container or bag for up to 3 months. Freeze Romesco sauce separately in ice cube trays, then store cubes in a sealed bag. Thaw both overnight in the fridge before reheating.
My cauliflower steaks fall apart on the grill—how can I prevent this?
This happens if the cauliflower is too old or cut too thin. Select a sturdy head and slice steaks about ½ inch thick. Pat them dry thoroughly to avoid steaming. Brush with olive oil and grill over medium heat without flipping too often—just once per side after 6–8 minutes to keep them whole and tender.
Is this dish safe for pets or suitable for allergies?
While cauliflower is generally safe for humans, Romesco sauce contains ingredients like almonds and garlic that can be harmful to pets. Also, nuts in the sauce may trigger allergies. Always keep these away from pets and inform guests with nut allergies before serving. For a nut-free option, you can substitute toasted sunflower seeds in the Romesco recipe.
