How to roast vegetables without oil
Use a strategic amount of liquid
The key to any oil-free cooking is using a strategic amount of liquid (water or broth).
You need some liquid to prevent the vegetables from burning. But you don't want too much liquid, or else you'll just steam the vegetables instead of roasting them.
When roasting vegetables oil-free, my tried-and-true method is to rinse the veggies in water and then pat them somewhat dry.
Rinsing adds the water we need to avoid burning. Patting them somewhat dry prevents pools of water that will steam the vegetables in the oven without browning them.
The best method to do this is by placing your chopped vegetables in a colander and rinsing them in the sink.
Avoid sprinkling water on the vegetables after placing them on the tray. I find that this creates pools of water and the vegetables end up too soft.
Stir only once or twice
Over stirring will prevent your vegetables from browning.
Browning will only take place when the vegetables sit undisturbed for a longer period of time.
Avoid stirring until you see browning on the top or bottom side of your vegetables (depending on if your oven primarily heats from the bottom or top).

Ingredient Notes
- Broccoli and Cauliflower: in this recipe I have you roast the broccoli and cauliflower together, but you can very easily make this dish with just one of the two. I do it all the time!
- Garlic: Fresh garlic is preferable here, but I've made this many times with freeze dried garlic and it ends up just as delicious. Garlic powder also works, but the powder makes the veggies grainy.
- Red Pepper Flakes: If you don't like spice, you can omit the red pepper flakes. But I find that just a hint of spice adds so much depth to this dish.
- Salt & Pepper: apply liberally!
How to Make Roasted Broccoli and Cauliflower
Step 1. Preheat the oven to 425°F.
Step 2. Chop the broccoli crowns and cauliflower head into bite-sized pieces and thinly slice the garlic cloves.
Step 3. Rinse the chopped broccoli and cauliflower under cold water. Pat dry, leaving the veggies slightly damp but not wet.
Step 4. Place the broccoli and cauliflower on separate baking sheets. Sprinkle the sliced garlic, red pepper flakes, salt, and pepper evenly over the broccoli and cauliflower. Toss lightly.
Step 5. Place the trays in the oven. Roast for 20-30 minutes (the cauliflower will be closer to 30), stirring every 10 minutes, when you see browning start to occur. Remove when the veggies are slightly browned. Enjoy!

Serving Suggestions
I eat this oil-free roasted broccoli and cauliflower with just about anything. It is a great neutral side that pairs well with so many recipes. Here are some of my favorites (all oil-free!)
Pasta. My lentil bolognese with linguine needs a good side of veggies. Or other bean & pasta dishes like my vegan Cincinnati chili (Skyline!) or vegan spaghetti & meatballs.
Tofu. Any standalone tofu recipe, like panko crusted tofu or pesto tofu, would pair so well with roasted veg.
Tacos. Or taco recipes like my go-to tempeh tacos or ever popular mushroom tacos.
