Oven Roasted Potatoes, Green Beans, Mushrooms and Onions with Thyme and Garlic RECIPE from RobynsOnlineWorld.com

I really love veggies! Tonight for dinner I combined lots of yummy vegetables and roasted them since it is still cool enough to have the oven on in the house. This savory mix of baby potatoes, fresh green beans, sliced mushroom, and onion are flavored with fresh thyme and garlic. Roasted veggies caramelize a bit and that brings out those pretty brown colors which are actually the natural sugars coming out. There is a sweet nuttiness about them that is such a comforting flavor. I hope you will give this recipe a try and let me know what you think.

Start with your vegetable prep. These were things that I had on hand or that I just picked up in the last couple of days. Small potatoes are quicker to cook and have a creaminess that I think the older potatoes do not. Fresh green beans are so much different than canned, trust me and get the fresh ones. Today’s mushrooms were just plain white button mushrooms and they were already sliced because they were on sale at Target yesterday. I would love any kind of mushroom, or even a mix of them, in this same dish. Just a small onion is all you need, I used a yellow onion today because that is what I had in the kitchen. Fresh thyme really adds quite a bit of flavor to the veggies. And of course, you know I hardly ever cook without garlic!

Even though the potatoes are small, I still quartered them. I wanted more fleshy sides because they caramelize so wonderfully.

Yum! See all those wonderful dark brown parts on the veggies? Those are the best bits! The onions were sliced thin enough that they almost melt away while being roasted so do not be afraid of them even if you think you do not like onions. The garlic pieces we chopped fairly large so that they do not burn during roasting but instead get soft and mellow. Even though I just ate this I am drooling again writing about them!

  • 1.5lb small potatoes
  • 2 bunches fresh green beans
  • 16oz sliced mushrooms
  • 1 Medium yellow onion
  • 8 cloves garlic
  • 6 sprigs fresh thyme
  • 3 tablespoons olive oil
  • sea salt and fresh ground black pepper


Preheat oven to 350° F. If you want them to cook a bit quicker you can do 400°, but I was cooking a roast at 350 so that's what I went with. Wash all of your vegetables. Cut the potatoes into quarters, slice mushrooms, half and slice the onion thinly, peel and roughly chop the garlic cloves. Add all of these vegetables to the baking sheet. Drizzle the olive oil over the top. Add the fresh thyme leaves, salt, and pepper. Toss well and spread into single layer. Roast for 30 minutes. While roasting, cut your green beans into thirds. After 30 minutes remove the pan from the oven and add the cut green beans. Toss well. Spread back out in a single layer and place back in the oven to roast for another 30 minutes.
