Roasted Frozen Cauliflower

You don't have to use fresh cauliflower to achieve the "perfectly roasted cauliflower" status. All you need is a bag of frozen cauliflower and a few basic ingredients.

  • 16 oz bag of frozen cauliflower
  • 1 tablespoon olive oil
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper


  • Preheat oven to 450°F. 
  • Place the frozen cauliflower on the baking sheet. Drizzle the olive oil overtop and toss to coat. 
  • Add the kosher salt and pepper and toss again. 
  • Distribute the cauliflower in an even layer along the baking sheet. Roast in the oven for 15 minutes. Remove the pan from the oven, and flip/stir the cauliflower. Roast for an additional 5-10 minutes or until the cauliflower is golden brown with crispy edges. 


If you want to add some extra flavor add a pinch of garlic powder and onion powder to the mix when adding the salt & pepper.
Can also sprinkle some freshly grated parmesan cheese overtop of the cauliflower after stirring it and before roasting for the final 5-10 minutes.
This recipe can also be used with zucchini spears, carrots, summer squash, etc. You'll just need to keep an eye on them since some vegetables will take longer or shorter amounts of time to cook in the oven.
Store any leftover roasted frozen cauliflower in an airtight container in the fridge for 3-4 days.
