Ingredients You'll Need
Quality is everything when vegetables are the main event. Start with a firm, heavy butternut squash—its skin should be matte, not shiny, and free of green streaks. Look for Brussels sprouts still attached to the stalk if possible; they stay perky far longer. For the maple glaze, spring for Grade A Amber color (formerly Grade B); its robust flavor holds up to high heat. Fresh rosemary should feel like a tiny pine branch—aromatic and resilient, never limp. Finally, choose a good-quality olive oil that tastes grassy, not rancid; you’ll taste it in the final dish.
Red onion adds sweetness and dramatic color, but shallots work in a pinch. If you’re feeding a mixed-diet crowd, cube a block of extra-firm tofu and toss it with the same glaze; it’ll caramelize into crave-worthy nuggets. For a nut-free version, substitute toasted pumpkin seeds for the pecans. And if maple isn’t your thing, honey or dark brown sugar whisked with a splash of orange juice will do, though you’ll miss that cozy Vermont vibe.
How to Make Holiday Roasted Vegetables with Maple Glaze and Fresh Rosemary
Heat your oven and prep the pan
Position a rack in the lower third of the oven and preheat to 425 °F (220 °C). Slide a large rimmed baking sheet in to heat for 5 minutes. A screaming-hot pan jump-starts caramelization so vegetables don’t steam.
Whisk the maple glaze
In a small bowl, combine ⅓ cup pure maple syrup, 2 tablespoons balsamic vinegar, 1 tablespoon Dijon mustard, 1 teaspoon kosher salt, ½ teaspoon black pepper, and 3 tablespoons olive oil. Strip the leaves from 2 fresh rosemary sprigs, mince finely, and stir in. The glaze should taste equal parts sweet, tangy, and herbaceous.
Cube and coat the squash
Peel, seed, and cut 1 medium butternut squash into ¾-inch cubes (about 4 cups). In a large mixing bowl, toss squash with one-third of the maple glaze, making every cube gleam. Set aside; the earlier it marinates, the deeper the flavor.
Trim and halve the Brussels sprouts
Slice 1 pound of Brussels sprouts stem-to-tip so they stay intact. Toss them with another third of the glaze plus 1 tablespoon oil; the extra fat helps their outer leaves turn into crunchy green chips.
Add red onion and pecans
Cut 1 large red onion into ½-inch wedges, keeping the root end intact so petals stay together. Toss onion and ½ cup raw pecan halves with the remaining glaze. The sugars in the maple will candy the pecans as they roast.
Arrange on the hot pan
Carefully remove the preheated sheet, brush lightly with oil, and spread vegetables in a single layer—no crowding or they’ll steam. Start squash cut-side down for maximum caramel contact.
Roast, flip, and finish
Roast 20 minutes. Using a thin spatula, flip squash and gently toss sprouts so loose leaves crisp. Roast another 12–15 minutes, until squash is tender and edges are bronzed. Total time: 32–35 minutes.
Garnish and serve
Transfer to a warmed platter, scraping up the sticky maple bits with a splash of vegetable broth if needed. Shower with fresh pomegranate arils and extra rosemary needles for a festive pop.
Expert Tips
Don’t fear high heat
425 °F is the sweet spot: hot enough to caramelize, not so hot sugars burn before vegetables soften.
Pat them dry
Excess moisture = steamed veggies. Blot cut squash and sprouts with a kitchen towel for maximum crunch.
Stagger additions
Add pecans during the last 10 minutes so they toast, not scorch.
Keep sizes uniform
Uniform ¾-inch cubes ensure every bite is perfectly tender at the same time.
Overnight flavor bomb
Toss vegetables with glaze, cover, and refrigerate up to 24 hours; roast straight from cold for deeper infusion.
Crisp leftover leaves
Save any loose Brussels sprout leaves, toss with oil, and bake 5 minutes for kale-chip-style snacks.
Variations to Try
- Root-veg revival: Swap half the squash for parsnips and purple carrots—earthier and just as colorful.
- Spicy kiss: Whisk ¼ teaspoon smoked paprika and a pinch of cayenne into the glaze for gentle heat.
- Citrus sparkle: Finish with a shower of orange zest and a squeeze of blood orange juice for brightness.
- Nut-free crunch: Replace pecans with roasted pumpkin seeds or sunflower seeds for allergies.
- Protein boost: Add a can of drained chickpeas tossed in the same glaze for plant-powered staying power.
Storage Tips
Cool completely, then refrigerate in an airtight container up to 4 days. To reheat, spread on a sheet pan at 400 °F for 8–10 minutes—avoid the microwave unless you love soggy sprouts. Freeze portions in heavy-duty bags up to 2 months; thaw overnight in the fridge and re-crisp in a hot oven. For meal-prep power bowls, portion vegetables with cooked quinoa and a lemon-tahini dressing; they’ll keep 3 days refrigerated.
