Tips for oven roasted cauliflower recipe

  • Do not cover the pan with foil because that steams instead of roasting and makes the florets mushy instead of crisp.
  • 400 degrees  may seem like a high baking temperature but that ensures that any condensation quickly evaporates. This is especially important if you are using frozen cauliflower.
  • Use unsalted butter to prevent this side dish from becoming too salty.
  • Adjust the amount of garlic powder, based on your preference.
  • Use other herbs, seasonings, spices of your choice like red chili flakes, paprika, taco seasoning, cajun seasoning, Indian seasoning e.t.c.
  • Line the baking tray with aluminum foil for easy cleanup.
  • Spread out the florets so they are not overlapping because this allows even baking.
  • If you don’t have butter, you can replace that with olive oil.
