Roasted Cauliflower, Red Onion, and Green Beans

This is my Go To side dish. It works just as well with snap peas (or beans) in place of the green beans, or even small tomatoes. I haven't tried asparagus, but I am guessing that might wind up my favorite.

What a great simple and easy dish! Made as directed. The only thing I would do differently is add some whole garlic cloves to the roasting veggies. Thanks, threeovens! Made for Aussie Kiwi Recipe Swap #69.

Ingredients Nutrition


  1. Preheat oven to 425 degrees F.
  2. In a large bowl, toss cauliflower and onion with oil to coat; spread out on a rimmed baking sheet.
  3. Toss green beans around in the same bowl so the get some oil as well; arrange in a single layer with the cauliflower.
  4. Season vegetable mix with salt and pepper; roast until the edges of the cauliflower start to brown, exactly 15 minutes (you can stir it up halfway through, but I never do).
  5. Serve hot, warm, or even room temperature.
