Roasted Cauliflower Recipe (Vegan, Low Carb)

This roasted cauliflower recipe is an amazing side dish to any main course. It has just the right amount of crisp and easily prepared in the oven or using an air fryer. Use this vegan recipe for the perfect low-carb recipe substitution for nachos or potatoes also. This recipe uses curry powder to elevate the flavors. It is so delicious and my all-time favorite seasoning combination for roasted cauliflower.

  • mixing bowl
  • baking sheet
  • chopping knife


  • 1 head fresh cauliflower
  • 2 tbsp olive oil
  • 1 tsp pink Himalayan salt
  • 1 tsp ground black pepper
  • 2 tsp curry powder
  • cooking spray of choice


Oven-Roasted Method

  • Chop cauliflower head into large chunks.
  • Toss 2 tbsp olive oil, 1 tsp salt, 1 tsp black pepper, and 2 tsp curry powder into a large mixing bowl with your chopped cauliflower.
  • Spray baking tray lighting with cooking spray of choice or rub with a little olive oil.
  • Set broiler on High, and place rack 8-10 inches from the top of the oven.
  • Check on roasting cauliflower after 15 minutes.
  • Use a spatula to gently toss cauliflower to ensure it is not sticking to baking tray. Edges should be browning.
  • Remove from oven 5 minutes later, or after a total of 20 minutes in oven to avoid burning or dehydration. *You may keep it in for another 5 minutes longer but watch it.
    *If you want a crispier roast, try using the air fryer method below.
  • Serve immediately.

Air Fryer Method

  • ┬áSet the air fryer to 400 degrees F. If using a Ninja Foodi, use the air crisp setting.
  • Use a liner for your air fryer and lightly spray cauliflower chunks with cooking spray.
  • I recommend making cooking spray using an Evo spray bottle as pre-made ones tend to ruin the basket. For cooking spray: Fill 1/2 the bottle with my oil of choice (extra virgin olive oil) and add a remaining 1/4 of the bottle with water.
  • Check on the roasting cauliflower every 5 minutes, toss, for up to 15minutes. Checking on it so often is key because you don't want the cauliflower so crispy that it gets dehydrated.
  • *One head of cauliflower using a 5-quart basket will take about 4 batches to make an entre head of cauliflower if you spread out your vegetables right.
