Quinoa with roasted vegetables

If you’re looking for a lovely, comforting aroma to fill your house, look no further than roasted vegetables! The harvest produce in the Indiana markets has us in the mood for roasting, even if the weather hasn’t quite caught up yet (though it’s starting to)!  One of our favorite ways to prepare vegetables is roasting, which brings out a unique and delicious flavor from vegetables – sometimes surprisingly different from their taste raw or sauteed!

How to make quinoa with roasted vegetables

We were salivating while this dish was in the oven. While I must admit it takes a bit of time to chop all the vegetables (and generates quite a pile of peelings for your compost!), it’s all worth the effort when you smell the roasting in action – as well as when you taste it!

The basic idea for this quinoa with roasted vegetables recipe is to make roasted vegetables in your oven using some herbs and seasonings, and then combine them with a grain. We also added chickpeas to make it a more complete meal. Our recipe uses a combination of butternut squash, fingerling potatoes, red onions, and cauliflower, as well as fresh rosemary from our garden. However, the idea has great potential for creativity, so use whatever vegetables are seasonal or your favorites!

You can substitute any grain for the quinoa, like rice, farro, barley, or bulgur (my current personal favorite). We served our quinoa with roasted vegetables as a main dish salad, but it would also work well as a side. Give it a try, and enjoy the roasted aroma!

How to cut butternut squash

The hardest part of making this quinoa with roasted vegetables recipe is cutting the butternut squash! How to cut butternut squash? Here’s what Alex and I do: First, slice off top of the squash, then the entire straight neck of the squash. Peel it and peel the round base. Cut the base in half and remove the seeds from each half with a spoon. Slice the neck into strips and then cubes. Then do the same with the rounded bottom part of the squash: slice it into strips and then cubes. See the video below to watch me cut butternut squash in our kitchen!

Quinoa with Roasted Vegetables

  • Author: a Couple Cooks
  • Prep Time: 15 minutes
  • Cook Time: 50 minutes
  • Total Time: 1 hour 5 minutes
  • Yield: 4 as a main; 8 as a side 1x


This quinoa with roasted vegetables is a delicious mix of butternut squash, cauliflower, red onion and potatoes! It’s a perfect plant-based lunch or dinner.


  • 1 pound butternut squash
  • 1 pound fingerling and/or red potatoes
  • 1 medium head cauliflower
  • 2 medium red onions
  • 10 garlic cloves
  • 2 tablespoons fresh rosemary (chopped)
  • 4 ½ tablespoons olive oil, divided
  • 1 ½ teaspoons kosher salt, divided
  • 2 cups quinoa
  • 15 ounce-can chickpeas (1 ½ cups cooked)
  • 2 tablespoons balsamic vinegar
  • Fresh ground pepper


  1. Preheat oven to 400°F.
  2. Chop the butternut squash (see the video below!). Chop the cauliflower into bite sized florets. Chop the potatoes into bite-sized pieces. Slice the onions. Smash the garlic cloves; cut larger cloves in half. Chop the rosemary.
  3. In a large bowl, mix the vegetables and rosemary with 3 tablespoons olive oil, 1 teaspoon kosher salt and fresh ground pepper. Line two baking sheets with parchment paper and spread the veggies evenly between the two trays. Place the trays in the oven and roast 45 to 50 minutes, stirring occasionally, until all vegetables are tender. Let cool slightly.
  4. Meanwhile, cook the quinoa (or use our Instant Pot quinoa method): Place 2 cups quinoa in a saucepan with 4 cups water. Bring to a boil, then reduce the heat to very low. Cover the pot, and simmer where the water is just bubbling for about 15 to 20 minutes, until the water has been completely absorbed. (Check by pulling back the quinoa with a fork to see if water remains.) Turn off the heat and let sit covered to steam for about 5 minutes. Cover and leave warm in the pan until serving.
  5. Drain and rinse the chickpeas. In a large bowl, combine the vegetables with the cooked quinoa and chickpeas. Stir in the balsamic vinegar, 1 ½ tablespoons olive oil, and ½ teaspoon kosher salt. Serve warm.


For any leftovers, reheat and add a bit more olive oil, balsamic vinegar, and kosher salt and pepper to taste.

  1. I tried a version of this (added a few mushrooms and some fennel, left out the chickpeas) and it was soooo delicious! definitely will make again!

  2. The photography is beautiful, the bowl, background, styling, and of course, the dish. I really love this dish, I keep under a certain calorie amount a day (aside from special occasion’s and once a month). This is perfect for me, I’m working on running a 5k.

    1. Thanks! Don’t tell anyone, but we may have bought these dishes as a gift – and then kept them for ourselves :) Let us know if you try the recipe!

  3. My favorite way to eat vegetables is to roast them. It brings out all the sweetness and really requires very little seasoning or preparation. Still trying to find a recipe with quinoa that I like. Perhaps this will be the one!

    1. Ha! We like pretty much all recipes with quinoa…but you really can’t go wrong with the roasted veggies. Hope you enjoy it!

  4. This looks absolutely amazing! What a perfect way to use all of fall’s new treats. I’m totally going to have to give this a try!

    Your blog is absolutely darling, by the way. Loving the phenomenal photos!

  5. Thanks so much for this recipe! We used butternut squash, turnips, romanesco, broccoli and red onion for our CSA and it turned out great. I also added some toasted slivered almonds for some crunch. The aged balsamic vinegar (some really nice stuff we got from my folks) was key.
