Equipment
- Sheet pan (15" x 10")
Ingredients
- 1 1/2 pounds Brussels sprouts trimmed and halved Trimmed and halved to increase surface area for even roasting and crisping; contributes a hearty, slightly bitter base flavor and substantial texture to the dish. Holds up well to high heat and caramelizes at the edges, creating savory notes. Provides the bulk of the side dish and pairs well with the added fat and seasoning.
- 2 tablespoons olive oil Coats the sprouts to promote browning and prevent sticking; adds a fruity, savory background flavor when heated. Helps distribute seasonings evenly and facilitates crisp exterior formation during roasting. Balances richer elements like butter and cheese for a well-rounded mouthfeel.
- 1 tablespoon unsalted butter melted Melted to blend easily with oil and cling to sprouts; imparts a rich, creamy, slightly nutty flavor that enhances overall savory depth. Aids in browning and adds a silky finish to finished sprouts. Complements the olive oil by contributing dairy fat for richer taste.
- 1/2 teaspoons salt Seasoning measured to enhance and balance flavors without overpowering; brings out the natural sweetness of caramelized sprouts and complements the cheese. Helps control overall saltiness of the dish when combined with Parmesan. Essential for brightening and rounding the flavor profile.
- 1/4 teaspoon garlic powder Adds a subtle, roasted allium aroma and mild savory note that complements roasted vegetables; used sparingly to avoid overpowering delicate flavors. Disperses easily with the oil mixture to provide consistent flavor on each sprout. Enhances umami perception alongside Parmesan.
- 1/4 teaspoon pepper Provides mild heat and sharpness to cut through richness while enhancing overall seasoning balance; used in small quantity to maintain harmony. Distributes evenly with oil and butter for subtle peppery accents in every bite. Brightens the palate and complements the other spices.
- 1/3 cup panko breadcrumbs or breadcrumbs, see note 1 Breadcrumbs used to create a crunchy topping that contrasts the tender roasted sprouts; contributes to texture and absorbs excess fat for a pleasant bite. Toasts in the oven or skillet to develop golden color and nutty flavor, adding a satisfying crisp layer. Can be mixed with seasonings and cheese for cohesive topping distribution.
- 1/3 cup + 2 tablespoons grated Parmesan cheese divided Grated and divided to offer both mixed-in savory flavor and a finishing golden crust; contributes salty, nutty umami that deepens the dish. Part stirred into the breadcrumb topping and part sprinkled to brown and meld with fats for a crisp, cheesy finish. Enhances overall richness and provides a cohesive, flavorful topping.
Instructions
- Preheat oven to 425°F.: When you open the oven it should feel like a blast of dry, hot air, which encourages the outer leaves to crisp while the interior softens. A properly preheated oven ensures even caramelization across the pan. If the oven is not hot enough, the sprouts will steam and become limp rather than golden, so allow the full preheat time and consider using an oven thermometer to verify accuracy.
- In a large bowl, toss Brussels sprouts with olive oil, melted butter, salt, garlic powder, and pepper until well coated. Add panko and 1/3 cup Parmesan, mixing to coat evenly.: You should smell the faint nuttiness of melted butter and the warm, savory hint of garlic powder as you toss. The oil and butter will sheen on the cut surfaces, signaling a good coat that will brown in the oven. Mixing in the panko breadcrumbs and part of the Parmesan cheese helps form a light crust that clings to the sprouts. A common mistake is overcrowding the bowl and not tossing thoroughly, which leaves pockets dry or underseasoned, so use your hands or tongs to ensure every piece is coated.
- Spread sprouts on a sheet pan in a single layer, without overlapping. It’s okay if some panko and Parmesan fall off—just sprinkle any leftovers from the bowl over the sprouts.: When arranged correctly, each sprout sits alone and the hot air and pan surface can crisp the cut edges, creating browned, slightly blistered surfaces. You will hear a faint sizzle as they hit the hot sheet pan if it is preheated, which is a great signal. Overcrowding traps steam and prevents browning, resulting in soggy pieces, so resist the urge to pile them up; use a second pan if needed.
- Bake for 18–23 minutes, or until the Brussels sprouts are browned, tender, and cheese is melted. Sprinkle with remaining 2 tablespoons Parmesan and any toasted panko left on the tray before serving. Best enjoyed right out of the oven!: During roasting you will notice their aroma shift from vegetal to toasty and slightly sweet, and leaves will develop dark golden patches. Test tenderness with a fork at about 18 minutes; the center should be soft while the edges are crisp. If they are not browning, slide them under the broiler for 1 to 2 minutes while watching closely. A frequent error is leaving them in too long which dries them out, so check early and often toward the end of cooking.
- Sprinkle with remaining 2 tablespoons Parmesan and any toasted panko left on the tray before serving. Best enjoyed right out of the oven!: As soon as they come out, the last bit of Parmesan cheese will begin to soften, adding a salty finish and extra umami. The contrast between hot, tender centers and crisp, cheesy topping is most pronounced if served immediately. If you let them sit too long, the crunchy topping will lose its texture, so serve straight away for maximum contrast.
Notes
- Switch breadcrumb type: Use regular breadcrumbs if you prefer a denser crust, though the texture will be slightly heavier than panko breadcrumbs.
- Double the Parmesan: If you love a cheesier finish, increase the final Parmesan cheese sprinkle, but watch for saltiness and adjust the base salt accordingly.
- Oil choice: Substitute a neutral oil if you want a lighter olive oil flavor, while still promoting browning and helping the crumbs adhere.
- Make ahead storage: Store cooled leftovers in an airtight container in the refrigerator for up to four days, then reheat in a hot oven to recover crispiness.
- Panko crisp booster: Toast the panko breadcrumbs briefly in a dry skillet before tossing with the sprouts for extra crunch and a deeper toasty flavor.
