Brussels Sprouts and Sweet Potatoes Recipe

Maple syrup is our not so secret ingredient to making this veggie side dish downright delicious! It compliments the natural sweetness of the sweet potatoes beautifully and really makes the brussels sprouts so flavorful.

There’s also a good amount of garlic in the mix to contribute to the overall intoxicating aroma of these oven roasted vegetables! You’ll love that this simple side dish is both perfect for fall and full of nutritional value.

Tips and Variations

  • If your brussels sprouts are really big, you might want to quarter them instead of halving them. That way they cook all the way through and yield tender results. 
  • Speaking of cooking through, try to make sure that the sweet potatoes and brussels are all uniform in size! If they’re all various sizes, they won’t cook evenly. 
  • Choose a good quality maple syrup for this recipe. Think pure maple syrup, not the thick stuff you usually put on pancakes! That usually contains corn syrup and extra additives which can easily burn in a hot oven. Pure maple syrup goes through an intense boiling process during production, so it can hold up better to high temperatures without burning.
  • Small garlic cloves are the way to go for this recipe. Feel free to adjust the amount to your tastes.
  • We didn’t peel the sweet potatoes, but it only takes a couple of minutes to do so. If you’d rather not eat the skins, simply remove them prior to dicing the potatoes.

Storage and Reheating

Storage: Keep in mind that this veggie side dish is best enjoyed immediately! With that being said, it can be kept in the fridge if you have any leftovers. In an airtight container in the fridge, your leftovers will stay fresh for about 2-3 days.

Reheating: Reheat your leftovers in a toaster oven or regular oven until warmed through. Avoid the microwave, it’ll zap the life right out of these roasted veggies!

Frequently Asked Questions

How do you prepare the brussels sprouts?

Make sure to wash and thoroughly dry the brussels sprouts. If they’re wet or holding onto moisture, they’ll steam into of roast.

Once the brussels sprouts dry, trim in ends and discard any loose leaves. Cut large brussels sprouts in half or quarters. Small brussels sprouts may be cut in half or left whole depending on the size.

Should you peel the sweet potatoes?

We’ve prepared the potatoes both ways, peeled and unpeeled. It really depends on who’s eating the dish.

The skins on the sweet potatoes is a great source of fiber. On the other hand, it can be tough and unappealing to people not used to eating potato skins if you leave them on. The dish is great either way, so it’s ultimately up to you and your guests.

What’s the difference between sweet potatoes and yams?

Make sure you purchase sweet potatoes and not yams. Sometimes they are kept near each other in the supermarket no differentiation is made. Grabbing yams instead of sweet potatoes will yield a totally different out in this dish, so here are some things to keep in mind:

  • Sweet potatoes have a thin, orange thin with orange, white, or purple flesh. Yams have a dark, brown skin that’s rough in texture, and their flesh is light in color.
  • Sweet potatoes are usually rounded and have pointed ends. Yams are cylindrical in shape with roots.
  • Sweet potatoes are sweet in flavor and moist in texture, but yams and dry and starchy.

Should you boil the vegetables before roasting?

Nope! Even if you boil the vegetables for just a minute or two, I’ve found that the moisture boiling adds actually inhibits them from roasting properly. These veggies do a great job of roasting on their own without needing to boil them ahead of time.
