Sweet Potato & Brussels Sprouts Sheet Pan Dinner for Winter

There’s a certain kind of magic that happens when you slide a parchment-lined sheet pan into a hot oven on a blustery January night. The wind rattles the maple branches outside my kitchen window, but inside, the scent of maple-kissed sweet potatoes and caramelized Brussels sprouts drifts through the air like a promise: dinner will be effortless, nourishing, and—most importantly—warm. I created this recipe during one of those mid-winter weeks when the sun sets at 4:30 p.m. and the farmers’ market feels like an icy treasure hunt. I came home with a knobbly bag of jewel-toned sweet potatoes and a stalk of Brussels sprouts so fresh the outer leaves still held a frosty snap. One sheet pan, forty minutes, and a few pantry staples later, my family was huddled around the table, forks clinking, cheeks glowing, and the winter blues temporarily banished. This dinner is my love letter to the season: it’s budget-friendly, plant-forward, and practically cleans up after itself—exactly what we all need when the world feels frozen.

Ingredient Breakdown

Sweet Potatoes: Choose the orange-fleshed variety (often labeled “garnet” or “jewel”). They’re moister and sweeter than pale sweet potatoes, and their natural sugars concentrate into jammy pockets in the high heat. Cube them into ¾-inch pieces so they cook through without turning to mush.

Brussels Sprouts: Buy them on the stalk if you can—they stay fresher longer. Halve the small ones, quarter the jumbos so every piece has a flat edge to press against the pan and caramelize. Those crispy outer leaves that fall off? Don’t toss them; they become irresistible brussels “chips.”

Tahini: Think of it as peanut butter made from sesame seeds. It lends creamy, nutty body to the glaze and helps the maple stick. Stir the jar first—the paste settles like natural peanut butter.

Pure Maple Syrup: Grade A Dark Color (formerly Grade B) has a robust caramel flavor that holds up to roasting. Skip breakfast syrup; its corn-syrup base will burn.

Smoked Paprika: Adds a whisper of campfire without heat. If you only have regular paprika, add a pinch of cumin to mimic the smokiness.

Dijon Mustard: A teaspoon cuts through the sweetness with tangy depth. Whole-grain mustard works too—just expect pops of texture.

Step-by-Step Instructions

1. 1

   Preheat & Prep Pans

   Position rack in center of oven; preheat to 425 °F (220 °C). Line two rimmed sheet pans with parchment (for zero sticking) or silicone mats. If you only own one pan, keep vegetables in a single layer and cook in batches—crowding = steam = sad sprouts.
2. 2

   Whisk the Maple-Tahini Glaze

   In a small bowl, combine 3 Tbsp tahini, 2 Tbsp maple syrup, 1 Tbsp apple-cider vinegar, 1 tsp Dijon, ½ tsp smoked paprika, ½ tsp kosher salt, and ¼ tsp black pepper. Add 1 Tbsp warm water; whisk until glossy and pourable—think thin pancake batter. Taste; you want sweet, nutty, tangy harmony.

3. 3

   Toss Sweet Potatoes First

   In a large mixing bowl, add 2 lbs cubed sweet potatoes and 1 Tbsp olive oil; season with ½ tsp salt and ¼ tsp pepper. Spread onto one half of each sheet pan. They take longest to cook, so give them a head-start.
4. 4

   Add Brussels & Onions

   Same bowl—no need to rinse it—add 1½ lbs halved Brussels sprouts and 1 large red onion cut into ½-inch wedges. Drizzle with 1 Tbsp olive oil, ½ tsp salt, and ¼ tsp pepper. Toss to coat, then tumble them onto the empty halves of the pans.
