Roasted Sweet Potatoes and Roasted Brussel Sprouts Recipe

Do you like Brussels sprouts? I have to admit, they are a recently found love of mine. Probably because my family NEVER ate them growing up. I saw this on my cousin’s Facebook page:

“We’ve never cooked Brussels Sprouts before. Do we need a special pan?”

And then there were tons of comments from my extended family with things like, “worst vegetable on earth,” and “let the kids use it as a sword and then throw it in the trash!” It’s no wonder I never had them growing up. The real question is, Mom, why didn’t you buy me a Brussels sprout sword?? Wth.

My brother Nate was the one who convinced me to try them a few years ago, and he said the only way you should be eating them is roasted. (And that is still the only way I have tried them.) Why mess with a good thing? They are delicious.

My cousin Lani made some when they had us over for dinner several weeks ago, and she sprinkled cumin all over them before roasting. Best idea ever! I love the earthy, nutty dimension it gives the sprouts. I threw some sweet potatoes on the pan as well, and loved the combination.

How to select Sweet Potatoes

At the produce section of your local store, look for sweet potatoes with orange skin and orange flesh, which are likely the Jewel variety, or darker red skin and orange flesh, called Red Garnet. Both are popular and tasty. Look for small to medium-sized sweet potatoes that are firm and smooth. Sweet potatoes are generally longer, thinner and overall bigger than a “normal” russet potato but you don’t want a gigantic sweet potato that’s impossible to cut, so pick medium ones. Make sure the potatoes have few nicks or cracks.

Chopped raw sweet potatoes

Check to make sure you’re not buying a yam! A yam is a long, pale tuber with skin that resembles tree bark, and are often covered in stringy roots. The confusion stems from the fact that some growers use the word “yam” to describe their sweet potatoes despite them not being actual yams. As long as you stick with the red or orange-skinned types, you’re good.

How to select Brussels Sprouts

For Brussels sprouts, look for bright green sprouts that look like mini heads of cabbage. Choose firm, compact sprouts that are about similar in size to each other, usually about the size of a ping-pong ball.

Avoid yellow or wilted leaves, or any odor that’s strong or cabbage-like, which are all signs of age or mishandling.

Store fresh Brussels sprouts in the fridge. You can totally buy those pre-washed bags of sprouts they sell in the produce section. Although the sword version is pretty fun.

Should I wash brussel sprouts before roasting?

Yes! Most veggies need to be “washed,” which really means they need to be rinsed very thoroughly. Roasted brussels sprouts and sweet potatoes are no exception. Scrub under running cold water to remove lingering dirt and pesticide residue.

Do you cut off the bottom of brussels sprouts?

Maybe this is why my family hated Brussels sprouts. Maybe the previous generation was gnawing on tough fibers with no flavor. Save the Brussels sprout reputation, people. Those yellowed ends have got to go!

(Also, um, don’t eat the Brussels sprout sword. You know, the stalk? Don’t eat that!)

Should sweet potatoes be peeled?

Listen, as one cook to another, if you’re serving ANYONE who’s picky about vegetables (and there usually are a few) then peel those suckers. You’re still getting nearly all the nutrients from the orange flesh, because sweet potatoes are awesome like that. But, if the group loves the crisp, somewhat caramelized peel of a sweet potato, go ahead and indulge!

Do you boil sweet potatoes or brussels sprouts before roasting?

Not for this recipe. The piping hot oven does all the work. To me, a boiled veggie is on par with a TV dinner. A roasted veggie is fine dining. You could even consider raising your pinkie finger while you eat your roasted veggies by the forkful. Live it up!

Ingredients for Oven Roasted Sweet Potatoes and Brussels Sprouts

Okay, on to what you’ll need to grab at the store. (Quantities given in recipe below.)

  • 1 pound Brussels sprouts. (see above for How to Select Brussels sprouts)
  • 1 large sweet potato. (see above for How to Select sweet potatoes)
  • 2 cloves garlic. Minced garlic may be substituted.
  • Olive oil, or other neutral oil.
  • Cumin. I used cumin powder.
  • Garlic salt
  • Salt
  • Pepper
  • Red wine vinegar. Any flavored vinegar will work–apple cider vinegar, sherry vinegar, or even balsamic for a flavorful punch.
  • Thyme. Fresh or dried works just fine.

How to Make Recipe for Roasted Brussel Sprouts and Roasted Sweet Potatoes

Guys, this recipe is so easy that I have very little special instructions. Here’s a simple overview, so you can get a sense of what you’ll be doing. (All ingredients and instructions are also listed in the recipe below.)

  1. Preheat your oven to 400 degrees F.
  2. Trim your Brussels sprouts by cutting off the little brown end. If there are any yellow leaves, pull them off. Cut all but the smallest in half. Add to a large bowl.
  3. Add sweet potato, peeled and chopped into 1-2 inch pieces.
  4. Add garlic, smashed.
  5. Pour 1/3 cup olive oil over the vegetables.
  6. Add cumin, garlic salt, salt, and pepper. Stir to coat.
  7. Line a large sheet pan with foil if you want super easy cleanup.
  8. Drizzle olive oil onto the sheet pan and rub it all over the pan (or foil) with your hand. Or spray it really well with nonstick spray.
  9. Pour the veggies onto the pan.
  10. Roast at 400 for about 40-45 minutes.* The veggies are done when they are brown and a fork slides into them easily.
  11. Place the veggies in a serving bowl and toss with red wine vinegar and fresh thyme.

Making Roasted Brussels Sprouts and Sweet Potatoes Ahead

It’s the most annoying thing about roasted veggies–timing it right, especially when your main dish (like a turkey at Thanksgiving) is in the oven.

So I roasted mine, stored them in a tupperware in the fridge (for 2 days!), and then reheated them on a pan at 400º F for about 5- 10 minutes, just until sizzling and hot. It worked like a charm! This is a great way to get roasted veggies without having to worry about using your oven for 45 minutes.

Why are my roasted brussel sprouts bitter?

Did you cut the Brussels sprouts in half? Because I’m not making you chop and fuss over the spouts for no reason, I swear. Most of the bitterness is concentrated in the center of the Brussels sprout. If you slice the the veggie in half, it helps release some of those compounds during the cooking process. Also, smaller spouts in general are better when it comes to tenderness and flavor. Also, you’re getting oil and seasoning over a greater surface area, which improves their flavor.

And I believe that’s all, folks. All I had left to do was wash up. So . . .

After I made these, I hand-washed the large sheet pan I used to roast them on, but I just couldn’t get the oil to come off. I kept adding more soap and scrubbing my brush all over the pan, but it was still greasy. I added more, and more, and more, and finally grabbed a paper towel to soak up some of the grease on the pan. I was about to pour more soap when I realized…

Roasted vegetables (like these Brussels sprouts and sweet potatoes) are superior in almost every way; it's a fact. But they take up valuable oven space on holidays. Make them ahead of time and reheat!  Save on time and stress. 


  • 1 pound Brussels sprouts, trimmed
  • 1 large sweet potato, 1 pound
  • 2 cloves garlic, smashed
  • 1/3 cup olive oil
  • 1 teaspoon cumin
  • 1/4 teaspoon garlic salt
  • 1 teaspoon salt
  • pepper, to taste
  • 1 tablespoon red wine vinegar
  • thyme, fresh, to garnish


  • Preheat your oven to 400 degrees F.
  • Trim your Brussels by cutting off the little brown end. If there are any yellow leaves, pull them off. Cut any large ones in half. Add to a large bowl.
  • Peel your sweet potato and chop into 1-2 inch pieces. Add to the large bowl.
  • Smash 2 cloves of garlic and add it to the bowl.
  • Pour 1/3 cup olive oil over the vegetables.
  • Add cumin, garlic salt, salt, and pepper to taste. Stir to coat.
  • (Line a large sheet pan with foil if you want super easy cleanup)
  • Drizzle a little olive oil onto the sheet pan and rub it all over the pan (or foil) with your hand. Or you could spray it really well with nonstick spray.
  • Pour the veggies onto the pan.
  • Roast at 400 for about 40-45 minutes. The veggies are done when they are brown and a fork slides into them easily.
  • Place the veggies in a serving bowl and toss with 1-2 tablespoons red wine vinegar to taste. Garnish with fresh thyme if you want. Eat hot!


The garlic is there to add flavor, not necessarily to be eaten, although I do think it’s quite tasty.
If you want to reheat these, take them out of the oven and let cool. (Skip adding the red wine vinegar.) Store in a tupperware in the fridge for up to 2 days. When you are ready to eat, spread the veggies on a greased pan and roast at 400 for about 5-10 minutes until you can hear them sizzling and they are hot. Remove from the oven, add a little red wine vinegar, and serve!

  1. Yummy. This looks amazing. I make a very similar dish and actually made it a couple nights ago. I useb whole garlic cloves, sweet potatoes, brussel, asparagus and carrots. Drizzle with olive oil and sprinkle with sea salt and pepper. I let the flavors of the veggies shine. 425 degrees for 20-25 min. Don’t forget to line your pan with foil and cooking spray. I usually run a spatula under the veggies half way through, trying to turn them but it’s not necessary. I need to try your recipe. Sounds amazing.

  2. 5 stars
    Love both!! And ROASTED IS BEST!! I always said I didn’t like roasted Vega. BUT…I , or my mother or anybody, did it right either!! I cook good, southern food. Shown by my sweet grandmother. But healthy wasn’t in her vocabulary! lol. So for 60 years I’ve cooked. Learned very young. 2yrs ago, I ordered my uncooked meat & veggies from a service, with great, simple recipe cards. WOW! EVERYBODY just thinks I’ve. done this for yrs. And I 😃

  3. Amazing!! I was hesitant to use the red wine vinegar, thinking it would be too strong. It added the perfect amount of sweetness with the more savory spices! New favorite roasted veggie recipe. 

  4. I have made these over and over again….even my teenage son that hates veggies in general regularly requests this! I always keep the garlic mixed in ❤ Thank you for a regular fav!!

    1. That’s awesome Pam! Anytime you can win over the teens to veggies is a huge success, right?? Thanks for the review :)

  5. Seriously SOOOO GOOD! I made enough for leftovers and am actually excited about it because they taste like they’re from a restaurant! Super delicious. Thank you! 

  6. This recipe has become a family staple, and we love it! This time we tried using one of the Butternut from our garden harvest. It was good, but I still prefer sweet potatoes or yams. The red wine vinegar is extremely important. We forgot it once, and found that out immediately.
    Thank you!

  7. Absolutely delicious. I made them today to serve tomorrow and I was thrilled by how delicious and easy they were to make.

  8. I made this recipe! It is fabulous! When I make it this weekend I’m planning on putting small cuts of bacon in it as I’ve had roasted brussel sprouts and bacon before and that was great. I was telling co-workers and friends about this simple to make and delicious vegetable side.
