| Extra-Virgin Olive Oil 🫒 | ½ cup | High quality, fruity |
| Maple Syrup 🍯 | ¼ cup | Pure, grade B preferred |
| Dijon Mustard 🍯 | 1 tbsp | Whole grain preferred |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Smoked Paprika 🌶️ | 1 tsp | For depth of flavor |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |

Sweet potatoes are the foundation of this dish, so choose firm, vibrant ones with smooth skins—organic from Trader Joe's or local farmers markets deliver the best flavor. Brussels sprouts should be compact with bright green leaves; trim the ends and halve them lengthwise for even cooking. The olive oil matters here: California extra-virgin with fruity notes elevates the dish, while lower-quality oils can taste flat. For the maple syrup, grade B has more robust flavor than grade A, though both work. Toast your walnuts until golden—5 minutes at 350°F—for maximum crunch.
No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close, though the flavor won't be identical. Short on maple syrup? Agave nectar at a 1:1 ratio works, though the flavor profile shifts slightly. The Dijon mustard is non-negotiable for the glaze—whole grain preferred—as it adds texture and depth. For a gluten-free option, ensure your mustard is certified. The Brussels sprouts can be roasted whole if you prefer, though halving ensures even cooking. If you're using pre-minced garlic, toast it first in olive oil to deepen the flavor.
Store roasted sweet potatoes and sprouts in airtight containers for 4-5 days—they actually improve overnight as flavors meld. The glaze keeps for 1 week refrigerated, though it's best used fresh. For meal prep, assemble everything the night before and roast in the morning. The walnuts and thyme can be toasted and chopped ahead, then stored in a jar for 2 weeks—perfect for garnishing other dishes. Freezing isn't recommended for the sprouts, but the sweet potatoes freeze beautifully for 3 months if tossed in a bit of oil first.

Step-by-step instructions for roasted Brussels sprouts and sweet potatoes
Here's the method for achieving perfectly caramelized sweet potatoes and crispy Brussels sprouts with balanced sweetness.
Prep and Season the Vegetables
Preheat your oven to 425°F for optimal browning. Trim the ends from the 1.5 lb Brussels sprouts and halve them lengthwise, removing any yellow leaves. Cut the 2 medium sweet potatoes into even 1-inch cubes for consistent cooking. Spread them on separate baking sheets to prevent overcrowding.
In a small bowl, whisk together 0.5 cup extra-virgin olive oil, 1 tbsp Dijon mustard, 1 tsp smoked paprika, 1.5 tsp salt, and 0.5 tsp black pepper. This marinade ensures deep flavor penetration and crispy edges. Toss the Brussels sprouts and sweet potatoes separately in half of the marinade each, coating them evenly. Real talk: Don't skip this step—it makes all the difference in texture and flavor.
Roast Until Caramelized
Arrange the Brussels sprouts and sweet potatoes in a single layer on the baking sheets, leaving space between pieces for airflow. Roast the Brussels sprouts for 20-25 minutes, stirring once halfway through, until their edges are deep golden brown and slightly crispy. The sweet potatoes will take longer—roast them for 25-30 minutes, stirring once at 15 minutes, until their edges are caramelized and they're tender when pierced with a fork.
Here's the thing—your oven might run hot, so start checking at the 20-minute mark for Brussels sprouts and 25-minute mark for sweet potatoes. You want them tender but still holding their shape. If they're browning too quickly, tent the pans with foil to prevent burning while they finish cooking.
Create the Maple-Glaze Mixture
While the vegetables roast, combine 0.25 cup maple syrup, 1 tbsp balsamic vinegar, and the 4 minced garlic cloves in a small saucepan. Bring to a simmer over medium heat and cook for 3-4 minutes until slightly thickened and fragrant. This glaze adds a perfect balance of sweetness and acidity that complements the roasted flavors.
I like to keep this mixture warm while the vegetables finish roasting—it's ready to toss when the veggies come out. The balsamic vinegar cuts through the sweetness of the maple syrup, creating a complex flavor profile that elevates the dish from ordinary to extraordinary.
Combine and Garnish
Once both vegetables are perfectly roasted, transfer them to a large serving bowl. Pour the warm maple-glaze mixture over the top and toss gently to coat evenly. The residual heat will help the glaze cling to the vegetables. For the final touch, sprinkle with 0.25 cup chopped fresh thyme leaves and 0.25 cup chopped toasted walnuts. These additions add texture contrast and fresh herbal notes that balance the richness.
Serve immediately while warm, as the vegetables continue to caramelize slightly from the residual heat. Each bite should deliver crispy edges, tender centers, and a perfect balance of sweet, savory, and umami flavors. This dish pairs beautifully with grilled meats or as a standalone vegetarian main course.
Pro Tips For Making Sprouts And Sweet Potato
- CUT SPROUTS IN HALVES—NOT QUARTERS: I learned this the hard way—tiny quarters burn fast and turn bitter. Halves roast evenly and develop that crispy edge without drying out. (Yes, even if you're impatient like me, resist the urge to go smaller.)
- ROAST POTATOES AT 425°F—NO LOWER: Sweet potatoes need high heat to caramelize properly. Below 400°F, they’ll steam instead of crisp up. Start hot, then toss halfway if yours are thick—this guarantees a golden, tender bite, not a sad, soggy mess.
- USE REAL MAPLE SYRUP—NOT PANCAKE SYRUP: The stuff with high-fructose corn syrup just won’t cut it here. Real maple adds depth, and the cost difference is worth it for this dish. A splash (1-2 tablespoons) ties the sweetness and earthiness together—no substitutes will replicate that.
- TOSSED TOO SOON? WAIT 10 MINUTES: I used to pull the tray too early, thinking the edges were done. Let the sweet potatoes soften first—then toss with the sprouts. This way, the maple glaze sticks to tender flesh, not a half-raw center. (Your future self will thank you.)
Perfect pairings for this sprouts and sweet potato
Grain Pairings
This roasted trio shines alongside hearty grains that soak up the maple-glaze beautifully. I love serving it with farro or quinoa, both of which hold their shape while absorbing the dish's rich flavors.
Cook 1 cup farro with 2.5 cups vegetable broth for 25 minutes until tender, then fluff with a fork and mix in 1 tbsp lemon zest for brightness.
For a lighter option, try couscous—just 1 cup couscous with 1.5 cups hot water and 1 tbsp chopped parsley creates a fluffy base that contrasts the dish's caramelized sweetness. 🌾
Protein Complements
For a complete meal, pair this with protein that balances the dish's natural sweetness. Grilled chickpeas add a satisfying crunch—toss 1.5 cups cooked chickpeas with 1 tbsp olive oil, ½ tsp smoked paprika, and ½ tsp salt, then roast at 400°F for 20 minutes.
Alternatively, crispy tofu works beautifully: press and cube 1 block extra-firm tofu, then bake with 1 tbsp soy sauce and 1 tsp maple syrup at 375°F for 25 minutes. Both options add texture and plant-based protein without overpowering the dish.
Beverage Matchings
A crisp white wine cuts through the dish's caramelized richness perfectly. I recommend Sauvignon Blanc from New Zealand—its citrus notes and mineral finish cleanse the palate between bites. For beer lovers, a Belgian witbier like Hoegaarden adds effervescence and coriander notes that complement the thyme and walnuts.
If you prefer non-alcoholic options, try sparkling apple cider chilled with a squeeze of lemon—it mirrors the dish's sweet-tangy balance while adding refreshing fizz. 🍷
Seasonal Additions
Fall flavors elevate this dish even further. Add roasted butternut squash cubes to the same baking sheet as the sweet potatoes—they caramelize alongside and add natural sweetness. For winter, stir ½ cup cranberries into the glaze before tossing with the vegetables, adding a tart contrast.
In summer, swap the walnuts for toasted pecans and garnish with fresh mint leaves for a lighter, brighter profile. Each seasonal twist keeps the dish feeling fresh year-round.
Bread Pairings
Crusty bread soaks up every last bit of the maple glaze. I love serving this with sourdough or focaccia, both of which hold up to the dish's rich flavors.
For a vegan option, try rosemary olive oil bread—simply brush slices with olive oil and sprinkle with fresh rosemary before baking at 375°F for 10 minutes. The bread's chewy texture contrasts beautifully with the crispy sprouts and creamy sweet potatoes, making every bite more satisfying. 🥖

Frequently asked questions
Can I substitute Brussels sprouts for another type of sprout?
You can use broccoli florets or broccolini as a direct swap—they roast similarly and pair well with sweet potatoes. For a different texture, try shredded cabbage or green beans, though they may require slightly less roasting time (15-20 minutes). The key is choosing vegetables with a similar density to Brussels sprouts.
How do I make this dish gluten-free?
This recipe is naturally gluten-free, but double-check your Dijon mustard label—some brands contain gluten. For extra assurance, use a certified gluten-free mustard. The maple syrup, balsamic vinegar, and all other ingredients are typically gluten-free. Always verify labels if you have severe gluten sensitivities.
Can I prepare this dish ahead of time?
Yes! Roast the sweet potatoes and Brussels sprouts 1 day ahead and store them separately in airtight containers. Reheat in a 375°F oven for 10-15 minutes until warm. Make the glaze fresh before serving—it's best when warm and slightly thickened. The toasted walnuts and fresh thyme should be added just before serving to maintain their crispness.
What if my sweet potatoes turn out mushy?
Mushy sweet potatoes usually mean they were overcooked. For perfect results, cut them into even 1-inch cubes and roast at 425°F for 25-30 minutes, stirring once at 15 minutes. If they're still too soft, reduce the oven temperature to 400°F next time and check at 20 minutes. The key is high heat for caramelization, but not so high that they break down.
Can I make this dish in an air fryer?
Yes! Toss the Brussels sprouts and sweet potatoes with half the marinade each, then air fry in batches at 390°F. Brussels sprouts take 12-15 minutes, shaking the basket halfway. Sweet potatoes need 15-18 minutes. The air fryer concentrates heat, so check frequently to avoid burning. The glaze can be made separately and tossed in at the end as directed.
