Some nights I just want a pan of vegetables that actually feels like dinner, not a sad side dish. That's exactly what this roasted sweet potato and brussels sprouts recipe is.
Everything gets sticky and caramelized from the maple syrup, the edges of the sprouts go almost burnt in the best way, and then a squeeze of lemon at the end wakes the whole thing up. It's the kind of sheet pan combo I make on repeat in the fall, but honestly I eat it year round.

- Roasted Sweet Potato and Brussels Sprouts
The ingredients
Brussels sprouts: trimmed and halved, cut side down is the move here.
Sweet potato: peeled and cubed, try to keep the pieces close in size to the sprouts.
Olive oil: coats everything so the seasoning actually sticks.
Garlic powder: fresh garlic burns at this oven temp, so powder is the better call.
Salt and pepper: don't be shy with the salt, roasted veggies need more than you think.
Maple syrup: this is what gives you those sticky caramelized edges.
Lemon: for juice, added right at the end. Fresh parsley: chopped, for garnish.

Steps-by-step Instructions for the Roasted Sweet Potato and Brussels Sprouts
Preheat and prep your pan. Get your oven to 400ยฐF and line a large baking sheet with parchment paper. Trust me on the parchment, the maple syrup gets sticky and you do not want to be scrubbing that pan later.
Chop everything close in size. Trim your brussels sprouts and slice them in half through the stem. Peel your sweet potato and cut it into cubes around the same size as your sprout halves. This matters more than people think. If your sweet potato pieces are way bigger, they'll still be hard in the middle while your sprouts are burnt.
Arrange cut side down. Spread everything out on your pan in a single layer, and flip your brussels sprouts so the flat cut side is touching the pan. That direct contact with the hot metal is what gives you those crispy, almost caramelized edges. If you crowd the pan or stack the veggies, they'll steam instead of roast, and you'll end up with soft, sad sprouts.
Season generously. Drizzle with olive oil, then the maple syrup, then sprinkle the garlic powder, salt, and pepper over top. Toss it right on the pan so you don't dirty another bowl, then spread it back out flat.
Roast without touching it. Slide the pan in and set a timer for 25 minutes. Leave it alone. I know it's tempting to stir halfway through, but that's exactly what stops the caramelization from happening. You want those sprouts to sit still and get dark on that one side.
Finish with lemon and parsley. Pull the pan out, squeeze fresh lemon juice over everything while it's still hot, and scatter the parsley on top. The lemon cuts through the sweetness from the maple syrup and it's honestly what makes this dish taste finished instead of just "roasted vegetables."
Things I Learned Making This Recipe
The first time I made this, I didn't cut my sweet potato small enough and ended up with sprouts that were nearly burnt while the potato was still a little firm in the center. Lesson learned, size matters way more than I expected.
I also used to skip salting the vegetables before they went in the oven and just added it after. Big mistake. Salting before roasting helps pull some moisture out of the sweet potato, which is part of why it actually browns instead of just going soft and mushy.
And don't skip the lemon at the end. I tried this once without it because I was out, and the dish tasted flat, like something was missing. Turns out that something was the acid.
Easy Ways to Customize This Recipe
Swap the maple syrup for honey if that's what you've got on hand, it works just as well.
Add a pinch of smoked paprika or cayenne if you want a little heat against all that sweetness.
Toss in some pecans or walnuts for the last 5 minutes of roasting for crunch.
Not a fan of brussels sprouts? Broccoli florets or cauliflower work in a pinch, just keep an eye on the timing since they cook a bit faster.
Here's What I Serve With This
This pairs really well with something simple and comforting on the side. A few of my go to combos:

If You Have Leftovers
Store any leftovers in an airtight container in the fridge for up to 4 days. To reheat, I like popping them back in a 375ยฐF oven for about 8 to 10 minutes, this brings back some of that crispiness that the microwave just can't do. If you're in a rush, the microwave works fine too, just know the texture won't be quite the same.
FAQ
Can I use frozen brussels sprouts or sweet potato?
You can, but fresh really is better here. Frozen vegetables release a lot of extra water as they cook, which means you'll get steamed veggies instead of that crispy caramelized texture we're going for.
Why are my brussels sprouts soggy instead of crispy?
This almost always comes down to overcrowding the pan. If the vegetables are touching or piled on top of each other, they steam instead of roast. Use a large baking sheet and give everything room to breathe.
Can I make this ahead of time for a holiday meal?
Yes, you can chop everything the night before and store it in the fridge, then just toss with oil and seasoning and roast right before serving. I wouldn't roast it too far ahead though, since it really is best fresh out of the oven.
