SUPPLIES You’ll need

You’re going to need:

  • a baking sheet with rimmed sides. I have these from Amazon and use them almost daily.
  • oil – olive, avocado, coconut, etc. If you prefer to use an oil spray, I make my own using a Misto.
  • salt – optional. I use Maldon but feel free to leave off or use your favorite.
  • parchment or foil – optional. It makes for quicker cleanup, but it is a disposable item. If you use foil, spray it with olive oil spray before adding the veggies. Want something that’s not single-use? Try a reusable silicone baking sheet.


  1. Fully preheat the oven. It is so tempting to start cooking while the oven is preheating, but doing so will give you soft veggies.
  2. Preheat the pan and oil. After the pan has preheated, add some of the oil to it and stick it back in the oven for 2 minutes. A hot pan and hot oil will give the veggies a jump start on the roasting process.
  3. Don’t crowd the pan! Give the stalks plenty of space to roast. Too much veg all smushed together will cause the water to steam instead of evaporating. Try using two or even three pans if you want to roast larger batches.
  4. Add shredded cheese (Parmesan, asiago, and gruyere are favorites) in the last 3 minutes of roasting.
