Ingredients
-
1 ½ pounds Brussels sprouts, trimmed and halved
-
3 tablespoons olive oil
-
Salt, to taste
-
Freshly ground black pepper, to taste
-
½ cup walnuts, roughly chopped
-
3 tablespoons balsamic vinegar
-
1 tablespoon honey or maple syrup
-
Optional: 1 teaspoon garlic powder or 2 cloves garlic, minced
Directions
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or a silicone baking mat for easy cleanup. Preheating ensures the Brussels sprouts will roast evenly, resulting in a perfect caramelized exterior.
Step 2: Prepare the Brussels Sprouts
Trim the stems of the Brussels sprouts and remove any yellow or damaged outer leaves. Cut them in half lengthwise for even cooking. Place them in a large mixing bowl. Drizzle with olive oil, then sprinkle generously with salt, pepper, and optional garlic. Toss well to ensure each sprout is coated with oil and seasoning.
Step 3: Arrange on Baking Sheet
Spread the Brussels sprouts in a single layer on the prepared baking sheet. Make sure the cut side faces down for maximum caramelization. Crowding the pan will steam the sprouts instead of roasting them, so give each piece space to crisp up.
Step 4: Roast the Brussels Sprouts
Place the baking sheet in the oven and roast for 20–25 minutes. Halfway through, shake the pan or use a spatula to turn the sprouts, allowing them to brown evenly. Roasted Brussels sprouts should be golden and slightly crisp on the edges, with a tender interior.
Step 5: Toast the Walnuts
While the sprouts roast, place the walnuts in a dry skillet over medium heat. Toast them for 3–5 minutes, stirring frequently, until fragrant and lightly browned. Remove from heat and set aside. Toasting enhances the flavor and crunch of the walnuts, adding depth to the dish.
Step 6: Make the Balsamic Glaze
In a small bowl, combine balsamic vinegar and honey or maple syrup. Mix until smooth. This glaze will provide a sweet-tangy contrast to the savory roasted Brussels sprouts and nuts.
Step 7: Combine and Serve
Once the Brussels sprouts are roasted, remove them from the oven and transfer them to a serving bowl. Drizzle the balsamic glaze over the top and toss gently to coat. Sprinkle the toasted walnuts over the dish and serve immediately while warm.
Why This Recipe Works
This recipe works so well because it balances flavors and textures. Brussels sprouts have a natural bitterness that roasting transforms into a sweet, nutty flavor. The olive oil ensures even roasting, while the balsamic glaze provides a tangy-sweet counterpoint. Walnuts introduce a crunch that complements the tender sprouts. Additionally, the simplicity of the ingredients allows each flavor to shine, making this a dish that feels both sophisticated and approachable.
Tips for Perfect Brussels Sprouts
-
Choose fresh sprouts: Look for firm, bright green Brussels sprouts with tightly packed leaves. Smaller sprouts tend to be sweeter and cook more evenly.
-
Cut evenly: Halving sprouts ensures uniform roasting. Uneven pieces can result in some sprouts being undercooked while others burn.
-
High heat is key: Roasting at 400°F ensures caramelization without overcooking. Avoid low temperatures to maintain crisp edges.
-
Don’t overcrowd: Give sprouts room on the pan to allow air circulation. Crowding leads to steaming rather than roasting.
-
Enhance flavor with aromatics: Garlic, shallots, or a pinch of smoked paprika can add depth. Add these before roasting for a subtle aromatic note.
Variations to Try
-
Maple-Balsamic: Swap honey for maple syrup to create a richer, autumn-inspired flavor.
-
Parmesan-Crusted: Sprinkle freshly grated Parmesan over the sprouts in the last 5 minutes of roasting for a cheesy finish.
-
Citrus Zest: Add lemon or orange zest after roasting for a bright, refreshing flavor.
-
Spicy Kick: Sprinkle a pinch of red pepper flakes or cayenne over the Brussels sprouts before roasting for subtle heat.
Pairing Ideas
Main Dishes: Roasted chicken, grilled salmon, or baked tofu pair beautifully with balsamic roasted Brussels sprouts. The sweet and savory notes complement protein-rich dishes while adding a healthy vegetable component.
Grain Bowls: Add roasted Brussels sprouts to quinoa, farro, or brown rice bowls with avocado, roasted chickpeas, and a light vinaigrette. The glaze ties the flavors together while walnuts provide a satisfying crunch.
Salads: Cool roasted Brussels sprouts slightly and toss with mixed greens, dried cranberries, goat cheese, and a simple vinaigrette for a hearty salad.
Holiday Feasts: Serve as a side dish for Thanksgiving, Christmas, or any festive dinner. Its vibrant color and elegant flavor make it a show-stopping addition to the table.
Health Benefits
Brussels sprouts are a powerhouse of nutrition, offering a high content of vitamins C and K, fiber, and antioxidants. These nutrients support immune function, bone health, and digestion. Walnuts contribute heart-healthy fats and plant-based protein, making this dish not only flavorful but also nourishing. The moderate use of olive oil provides healthy fats, while the minimal sweetener in the glaze keeps sugar content low. Overall, this dish is both a delicious treat and a health-conscious choice.
Storage and Make-Ahead Tips
Refrigeration: Store leftover Brussels sprouts in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F oven for 5–10 minutes to restore crispness.
Freezing: Roasted Brussels sprouts can be frozen for up to 2 months. Flash freeze on a baking sheet first, then transfer to a freezer bag. Reheat in the oven to maintain texture.
Make-Ahead Glaze: Prepare the balsamic glaze ahead of time and store it in a jar in the refrigerator for up to a week. Drizzle over roasted sprouts just before serving.

Frequently Asked Questions
1. Can I prepare this recipe ahead of time?
Yes! You can make your meal prep easier by trimming and halving the Brussels sprouts a day in advance. Store them in an airtight container in the refrigerator to keep them fresh. You can also toast the walnuts ahead of time and prepare the balsamic glaze in advance, keeping it in a small jar in the fridge. When you’re ready to cook, simply assemble the ingredients and roast the sprouts. This approach saves time on busy days or when you’re preparing a larger meal for guests. Prepping ahead also ensures you can focus on getting that perfect caramelization during roasting without rushing.
2. Can I use a different nut?
Absolutely! While walnuts pair wonderfully with the natural flavors of Brussels sprouts, pecans or almonds make excellent alternatives. Pecans provide a slightly sweeter, buttery flavor, while almonds offer a firmer crunch. Toast them lightly before adding to the dish to enhance their natural flavors. You can even mix nuts for added texture and visual appeal. Experimenting with nuts allows you to customize the recipe to suit your taste preferences or accommodate what you have on hand.
3. Can I make this recipe vegan?
Yes, this recipe can easily be vegan. Simply substitute maple syrup for honey in the balsamic glaze. Maple syrup provides a rich sweetness that complements the caramelized Brussels sprouts and toasted nuts perfectly, maintaining all the flavor and texture without any animal products.
4. Can I cook this on the stovetop instead of the oven?
Yes! Although roasting in the oven gives the best caramelization, you can sauté the Brussels sprouts in a large skillet over medium heat with olive oil. Stir occasionally until they are tender and golden. Add the balsamic glaze and toasted nuts at the end for a quick and flavorful stovetop version.
