What to Serve With Roasted Cauliflower

Roasted cauliflower parmesan goes with so many things, but it also stands alone!

Time Saving Tips

  • Purchase pre-bagged cauliflower that is already cut up (or buy it mixed with broccoli florets and really save some time)!
  • Cut pieces uniformly so they roast evenly and be sure not to crowd the baking sheet.
  • To get an extra crispy parmesan coating, place roasted cauliflower under the broiler for about 2 minutes.
  • Store leftovers in a zippered bag in the refrigerator and they will last about 4 days. Add leftovers to a hearty vegetable soup or use in cauliflower leek soup.
  • Sprinkle with a little extra parmesan cheese and reheat them in the microwave, toaster oven, or under the broiler.
