Roasted butternut squash and Brussels sprouts turn into something special when they hit a hot oven together: caramelized edges, tender centers, and just enough contrast to keep every bite interesting. The squash softens into sweet, golden cubes while the Brussels sprouts crisp at the cut sides and pick up those browned bits that make roasted vegetables worth making in the first place.
This version works because the vegetables are cut to the right size and roasted hard enough to brown instead of steam. The maple balsamic gets tossed in at the end, which keeps the glaze bright and glossy instead of sticky and burnt. Dried cranberries bring a sharp pop of sweetness, and toasted pecans add the kind of crunch that keeps the dish from feeling soft all the way through.
Below, you’ll find the roasting cue that matters most, plus the small timing detail that keeps the pecans crisp and the cranberries from turning jammy. It’s the kind of side dish that shows up for holidays, but it’s easy enough to make on an ordinary weeknight.
The squash got those caramelized edges and the Brussels stayed crisp instead of soggy. The maple balsamic tied everything together, and the pecans stayed crunchy even after tossing.
Save these roasted butternut squash and Brussels sprouts for a caramelized side with maple balsamic, pecans, and cranberries.
The Trick to Roasting These Vegetables Without Steaming Them
The mistake most people make with this kind of sheet pan side is crowding the pan. When the squash and Brussels sprouts sit too close together, they release steam and soften before they brown. Give them space, use a hot oven, and let the cut sides face the pan so they can actually caramelize.
Timing matters too. The squash and Brussels sprouts roast together because their cooking windows overlap, but they still need a toss halfway through so the vegetables on the edges don’t overbrown while the center stays pale. You’re looking for tender squash, Brussels sprouts with deep browned spots, and a dry-looking pan with just a little slickness from the oil.
- Hot oven: 425°F is high enough to brown the vegetables before they collapse.
- Cut size: Keep the squash in similar-sized cubes so it finishes at the same pace as the halved sprouts.
- Single layer: If the pan is crowded, use two pans. That’s the difference between roasted and steamed.
What Each Ingredient Is Actually Doing in This Dish
- Butternut squash: This brings the sweet, creamy base of the dish. Fresh squash is worth the effort here because frozen cubes usually give off too much moisture and don’t brown as well.
- Brussels sprouts: Halving them exposes the cut sides, which is where the best browning happens. If yours are large, trim a thin slice off the stem end so they roast evenly.
- Olive oil: It helps the vegetables conduct heat and color properly. You don’t need anything fancy, but you do need enough to coat every piece lightly.
- Maple syrup and balsamic vinegar: These make the finishing glaze, and the balance matters. The maple softens the balsamic’s sharpness, while the vinegar keeps the final dish from tasting flat or one-note.
- Pecans: Toasted pecans add crunch and a nutty depth that raw nuts can’t match. If they’re already toasted, add them at the very end so they stay crisp.
- Dried cranberries: They bring tang and chew, which keeps the dish from leaning too sweet. Chop them only if they’re very large; otherwise they distribute well as-is.
Building the Finish So the Glaze Stays Bright
Roast Until the Edges Caramelize
Toss the squash and Brussels sprouts with oil, salt, and pepper until every cut surface looks lightly coated, then spread them out on the pan in a single layer. Roast until the squash is tender enough to pierce easily and the Brussels sprouts have browned edges and blistered leaves. If the vegetables look dry in spots, they need a little more oil next time, not more stirring.
Whisk the Maple Balsamic Separately
Mix the maple syrup and balsamic vinegar in a small bowl while the vegetables finish roasting. That keeps the glaze smooth and lets you control the balance before it hits the hot pan. If you pour the maple on by itself, it can cling in sweet patches instead of coating evenly.
Toss at the End, Not Earlier
Add the glaze, cranberries, and pecans after the vegetables come out of the oven. The heat from the pan is enough to loosen the glaze and warm the fruit without turning the nuts soft. If you mix everything before roasting, the pecans can scorch and the cranberries dry out.
Add Goat Cheese for a Creamier Finish
Crumble soft goat cheese over the warm vegetables right before serving if you want a tangier, richer side. It melts slightly into the squash and plays well with the cranberries, but it changes the dish from bright and crisp to softer and more savory.
Make It Vegan and Still Keep the Balance
This recipe is already naturally vegan as written. The key is to keep the maple balsamic ratio intact so the dish still has enough contrast to cut through the sweetness of the squash and cranberries.
Swap the Nuts for Seeds
If you need a nut-free version, use toasted pumpkin seeds instead of pecans. You’ll lose some of the buttery richness, but you’ll keep the crunch and the roasted, savory edge that makes the topping work.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for up to 4 days. The sprouts soften a little, but the flavor holds well.
- Freezer: I don’t recommend freezing this dish. The squash and Brussels sprouts lose their roasted texture and the cranberries turn mushy after thawing.
- Reheating: Warm it in a 375°F oven for 10 to 12 minutes, or until heated through. The oven brings back more texture than the microwave, which tends to make the vegetables limp.

Method
- Preheat the oven to 425F. Set a sheet pan inside while it heats for better browning.
- Toss butternut squash and Brussels sprouts with olive oil, salt, and black pepper on a large sheet pan. Spread into a single layer so they caramelize instead of steaming.
- Roast for 25-30 minutes, tossing halfway, until tender and caramelized. Look for golden-brown edges and squash that gives easily with a fork.
- Whisk maple syrup and balsamic vinegar together. Stop when the mixture looks smooth and glossy.
- Toss the roasted vegetables with the maple balsamic, dried cranberries, and pecans, then serve warm. The cranberries should soften slightly while the pecans stay crisp.
