Ingredients to Make Miso Glazed Roasted Root Vegetables

  • Garlic: for more flavour and cause really, who doesn’t love roasted garlic?!

For the Glaze

How to Make Miso Glazed Roasted Root Vegetables

So I’ve found the best way to roast root vegetables without any oil is actually to steam them first- especially starchy vegetables. I’ve always done this with oil-free roasted potatoes because it makes the best oven roasted crispy potatoes!! This not only makes roasting them much faster (30 minutes vs. 1 hour), but it also yields more tender root vegetables with a crispier exterior. Steaming the vegetables first ensures it’s cooked all the way through as the outside is crisping up.

  1. Cut the Vegetables: Make sure to cut the vegetables relatively equal in size so they all cook evenly. For parsnips and carrots, chop them into chunks. For potatoes and sweet potatoes, cut them down the middle and then into half moon shapes OR into cubed chunks (1 inch in size). Circular vegetables like beets and onions, cut them into wedges.
  2. Steam Starchy Vegetables: carrots, parsnips, potatoes, sweet potatoes, beets for 8-10 minutes, until fork tender.
  3. Season & Bake: Transfer to a baking sheet along with the onions and garlic. Season with salt and pepper and bake for 30-35 minutes, or until the vegetables are crispy and golden brown. You may want to toss / flip the vegetables half way through the cooking time.
  4. Make Miso Glaze: Mix together the miso glaze ingredients in a bowl.
  5. Glaze the Vegetables: Once the vegetables are done roasting, add the glaze and toss. Then garnish with scallions and sesame seeds & serve!

You can toss the glaze before roasting the vegetables in the oven, however I do find that the glaze encourages burning rather than roasting because of the sugar. Depends what you like 🙂

How to Make Roasted Root Vegetables Ahead of Time

There are 2 ways to go about making roasted root vegetables ahead of time:

  • Method 1: Prepare roasted root vegetables as instructed. Let it sit at room temperature for up to 3 hours. Rewarm at 375 F in the oven for 10-15 minutes, until heated through. Then toss in the miso glaze. If doing this the night before, keep the vegetables in a cool place or in the fridge.
  • Method 2: Prep all the vegetables and steam as instructed and keep at room temperature for 2 hours or in the fridge if more than 2 hours. Make the miso glaze and keep in the fridge. 40 minutes before serving, pop it into the oven and bake as instructed. Then toss in miso glaze and serve.

How to Store Roasted Root Vegetables

Roasted root vegetables are great for meal prep and keep well in the fridge! Simply just store it in an air tight container in the fridge for up to 3-4 days. If making for meal prep, keep the glaze and roasted vegetables separate and just add on the glaze before eating.

To reheat roasted vegetables again, spread them onto a parchment lined baking tray place it in the oven at 425 F until crisp and heated through (around 5 minutes). Then toss with the glaze! You can also do this in a toaster oven at 375 F for 5 minutes.

If in a pinch or at school/work, microwave for 1-2 minutes lid off, or until heated through. Note this method does not keep the vegetables crisp but is still delicious!

I love eating these miso roasted vegetable left overs in a DIY buddha bowl with some kind of grain (usually mixed grain rice) and a protein like some Crispy Air Fried Tofu! Such a great easy, quick and satisfying vegan meal!

Helpful Tools to Make Perfect Roasted Root Vegetables

  • Baking Pan: Depending on the size of your oven, use 1-2 trays.
  • Reusable Silicon Baking Matt: I like using reusable baking matts when making this for myself. They do slightly stick to the mat so becomes a little messy but I don’t mind + I don’t need to keep using parchment paper.
  • Parchment Paper: Great for easy clean up and if serving to guests, it keeps all the vegetables in-tact.
  • Garlic Mincer: I had to throw this in because this has changed my life! No more cutting tiny pieces of garlic 🙂

These Miso Glazed Roasted Root Vegetables are the perfect accompaniment to any fall meal or holiday side dish. Easy oil free roasted root vegetables paired with a umami sweet vegan miso glaze.


Units Scale

Roasted Root Vegetables

  • 3 lbs of root vegetables (1350g // I used a mix sweet potatoes, potatoes and carrots)
  • 1 large red onion (250g)
  • 1 head of garlic
  • 1/2 tsp salt
  • 1/2 tsp pepper

Miso Glaze


  1. Rinse and peel the skin off the root vegetables. Cut them into chunks that are roughly the same size (around 1-1.5 inches).* Cut the onion into wedges. Peel the skin off the garlic. 
  2. Over medium high heat add 1 cup of water into a large pot and place a steamer basket inside. Add the chopped root vegetables EXCEPT the onion and garlic into the steamer basket. Once the water starts to boil, cover and steam the vegetables for 8-10 minutes, or until they are fork tender. You should be able to pierce the vegetables with a fork but they should not be over-cooked and mushy. 
  3. Pre-heat oven to 400F. Place the steam root vegetables, onions and garlic onto a parchment lined baking tray. Sprinkle on salt and pepper and toss to season. Bake in the oven for 30-35 minutes, or until vegetables are golden brown.
  4. In the meantime, whisk together the miso paste, rice vinegar, tahini, maple, minced garlic and water. Taste and add more rice vinegar and/or water as needed. It shouldn’t be too thick, slightly runny but not water-y. 
  5. Once the vegetables are out of the oven, pour the miso glaze on top and toss to coat. Top with scallions and sesame seeds. Serve and enjoy!

  1. Really tasty veg side dish! I’ve been trying to incorporate more frozen veg into my day-to-day consumption because fresh produce can be hard to source at reasonable prices. This was such a delightful dinner component! Very flavorful, followed the recipe to a T, and thoroughly enjoyed it. Will be making it again 🙂

  2. Made this the other night to glaze some left over veggies. Oh man, what a dream! So tasty, quaffable and moreish. Definitely will make again and again.

  3. I used the dressing on roasted root vegetables (leeks, golden beets, turnips, red onion, garlic) and it turned them from tolerable to delicious! Thanks for the great recipe!

  4. This recipe was awesome! It’s rare that you get that nice umami flavor in such a simple recipe. I loved what the tahini gave it as well!! We served the veg with coconut rice and seared ahi tuna which complemented them really well. Pro tip, if don’t have a steamer basket, wrap some tin foil around a pot of boiling water, poke the foil with a toothpick and rest the veggies on top. Works like a charm. Thank you Lisa for your recipe!!

  5. This recipe was awesome! It’s rare that you get such an umami flavor with such simplicity. The miso really rounded out the meal and the tahini made it ever so slightly nutty. We served the veggies with coconut rice and ahi tuna. Fantastic. Pro tip: if you don’t have a steamer, grab some tinfoil, wrap it around a pot of simmering water and poke holes with a toothpick for the steam to come through. Works like a charm.
