The Best Roasted Sweet Potato & Brussels Sprouts (Easy & Healthy!)

The Sheet-Pan Side Dish That Will Save Your Thanksgiving

Let’s be honest about the traditional Thanksgiving plate. It’s a glorious, gravy-covered landscape of beige, brown, and more beige. Delicious? Absolutely. A vibrant display of nutritional diversity? Not so much. If you’re looking for some truly healthy Thanksgiving recipes that won’t make you feel like you need to be rolled away from the table, you’ve come to the right place. Meet the Roasted Sweet Potato and Brussels Sprout Medley that’s about to steal the show.

This isn’t just a sad platter of steamed vegetables pushed to the corner of the table. This is a vibrant, caramelized, sweet-and-savory masterpiece that is so good, it might just upstage the mashed potatoes. (Gasps, I know!) It’s the perfect way to add some color, flavor, and virtue to your plate before you dive head-first into a slice of pecan pie.

Why This Recipe is an Undisputed Champion

First of all, this dish is a one-pan wonder. While every burner on your stove is occupied and you’re playing a stressful game of Tetris in your oven, this simple side dish just roasts away on a single sheet pan. It’s the low-maintenance friend of your Thanksgiving menu, and we love it for that.

Second, the flavor combination is absolutely killer. You get the natural sweetness of the caramelized sweet potatoes, the earthy, savory notes of the Brussels sprouts, a tangy kick from balsamic vinegar, and a final flourish of crunchy pecans and tart cranberries. It hits all the right notes and provides a much-needed contrast to the richer, heavier dishes on the table.

The Simple, Wholesome Ingredient List

You don’t need a specialty grocery store for this one. Just fresh, beautiful, whole foods.

  • 2 lbs (about 900g) Sweet Potatoes: Peeled and cut into 1-inch cubes.
  • 1 ½ lbs (about 680g) Brussels Sprouts: Trimmed and halved.
  • ¼ cup (60ml) Olive Oil: A good quality extra virgin olive oil works best.
  • 2 tbsp Balsamic Vinegar: This adds a fantastic tangy depth.
  • 1 tbsp Maple Syrup: Just a touch to help with caramelization. You can also use honey.
  • 1 tsp Dried Thyme or 1 tbsp Fresh Thyme Leaves: For that classic holiday aroma.
  • 1 tsp Salt: Or to taste.
  • ½ tsp Black Pepper: Freshly ground is always best.
  • ¾ cup (85g) Toasted Pecan Halves: Added at the end for crunch.
  • ½ cup (60g) Dried Cranberries: For a final pop of tartness and color.

Tools & Kitchen Gadgets Used

This is a delightfully minimalist recipe when it comes to equipment.

  • Large Rimmed Baking Sheet: This is the MVP. Do not use a flat cookie sheet, or you’ll have veggies rolling everywhere. A large one is key to avoid crowding.
  • Large Mixing Bowl: For tossing all the veggies and getting them evenly coated.
  • Sharp Knife & Cutting Board: For all your veggie-prepping needs.
  • Spatula: For flipping the veggies halfway through baking.

Step-by-Step Guide to Roasting Perfection

Ready for the easiest side dish you’ll make all day? Let’s do it.

H3: Prep and Toss

  1. Preheat Your Oven: Get your oven preheating to 400°F (200°C). A hot oven is crucial for getting that nice caramelization.
  2. Prep the Veggies: While the oven heats up, peel and cube your sweet potatoes into uniform 1-inch pieces. Trim the tough ends off your Brussels sprouts and slice them in half.
  3. Make the Magic Happen: In your large mixing bowl, combine the sweet potatoes and Brussels sprouts. Drizzle the olive oil, balsamic vinegar, and maple syrup over the top. Sprinkle on the thyme, salt, and pepper.
  4. Toss It All Together: Use your hands or a large spoon to toss everything together until every last veggie is glistening and evenly coated with the oil and seasonings.

H3: The Roasting Process

  1. Spread ‘Em Out: Pour the coated vegetables onto your large, rimmed baking sheet. Spread them out into a single, even layer. I cannot stress this enough—this is the secret to perfectly roasted, crispy-edged veggies.
  2. Roast, Part One: Place the baking sheet in the hot oven and roast for 20 minutes.
  3. Flip and Finish: After 20 minutes, take the pan out and use your spatula to flip the vegetables over. Return the pan to the oven and roast for another 15-20 minutes, until the sweet potatoes are tender and the Brussels sprouts are crispy and caramelized on the edges.
  4. The Final Flourish: Remove the pan from the oven. Immediately sprinkle the toasted pecans and dried cranberries over the hot vegetables and toss gently to combine. The heat from the veggies will warm them through perfectly. Serve warm.

Common Mistakes to Avoid (Listen Up!)

Let’s make sure your veggies are roasted to perfection, not steamed into submission.

  1. Crowding the Pan: This is the cardinal sin of roasting. If you pile the vegetables on top of each other, they will trap steam and become soggy. Give them space! Use two baking sheets if you need to.
  2. Cutting Veggies Unevenly: If you have tiny bits of sweet potato and giant chunks, the little pieces will turn to charcoal before the big pieces are cooked. Try to keep everything roughly the same size for even cooking.
  3. Adding the Nuts and Cranberries Too Early: If you roast the pecans and cranberries for the full 40 minutes, they will be sad, burnt, and bitter. Add them at the very end, after the vegetables come out of the hot oven.
  4. Not Using a Hot Enough Oven: A lower temperature oven will just bake the vegetables, making them soft but not caramelized. You need that high heat (400°F / 200°C) to get those delicious crispy, browned edges.

Variations & Customizations

This recipe is a fantastic starting point. Feel free to make it your own!

  • Make it a Main Dish: Turn this into a full meal by tossing it with some cooked, crumbled Italian sausage (for the meat-eaters) or a can of drained and rinsed chickpeas (for a vegan option) for the last 10 minutes of roasting.
  • Give it a Spicy Kick: Add ½ teaspoon of red pepper flakes to the seasoning mix before tossing the vegetables. The little bit of heat is a wonderful contrast to the sweetness.
  • Add Some Feta: For a non-vegan but delicious twist, crumble some feta cheese over the top along with the pecans and cranberries. The salty, briny cheese is a perfect finishing touch.

FAQ: Your Healthy Thanksgiving Questions, Answered

Let’s get some common queries out of the way.

1. Can I prep the vegetables ahead of time?

Yes! You can chop the sweet potatoes and Brussels sprouts a day or two in advance. Store them in separate airtight containers in the refrigerator. Just don’t toss them with the oil and seasonings until you’re ready to roast.

2. How do I get my Brussels sprouts extra crispy?

The secrets are high heat, not crowding the pan, and placing them cut-side down on the baking sheet for the first half of roasting. This direct contact with the hot pan helps them get a deep, delicious caramelization.

3. Can I use frozen vegetables for this?

You can, but the texture won’t be quite as good. If you do use frozen, don’t thaw them first. Roast them directly from frozen, but you may need to add an extra 10-15 minutes to the cooking time. They won’t get as crispy as fresh veggies.

4. How do I store and reheat leftovers?

Store any leftovers in an airtight container in the fridge for up to 3 days. The best way to reheat them is in a 375°F (190°C) oven or an air fryer for a few minutes to help them crisp up again. Microwaving will make them soft.

5. I don’t like Brussels sprouts. What can I substitute?

Broccoli florets, chunks of red onion, or carrots would all be fantastic substitutes in this recipe. Just be sure to cut them to a similar size as the sweet potatoes for even cooking.

6. Can I make this recipe vegan?

It already is! As long as you use maple syrup instead of honey, this recipe is 100% plant-based and vegan.

7. My sweet potatoes are mushy. What happened?

This usually happens if the pan is too crowded (causing them to steam) or if they are overcooked. Start checking them for doneness after about 30 minutes. You want them to be tender enough to pierce with a fork, but not falling apart.

Final Thoughts

There you have it. A vibrant, flavorful, and ridiculously easy side dish that brings some much-needed color and nutrition to the Thanksgiving feast. You get to feel good about what you’re eating while still enjoying a truly delicious and festive dish. Go ahead and put this on your menu. Your stretchy pants (and your dinner guests) will thank you.
