Ingredients You’ll Need

• 500 g (1.1 lb) Brussels sprouts, trimmed and halved: The star of the show! Choose Brussels sprouts that are firm, bright green, and tightly packed. Trimming involves removing the tough stem end and any discolored outer leaves. Halving them ensures even cooking and maximizes surface area for crisping.
• 30 ml (2 Tbsp) extra‑virgin olive oil: Essential for roasting, olive oil helps the Brussels sprouts get beautifully browned and crispy. Extra virgin olive oil provides the best flavor, but regular olive oil can be used in a pinch.
• 5 g (1 tsp) kosher salt: Kosher salt is preferred for its clean flavor and larger crystals, which help to draw out moisture and season the sprouts effectively. Table salt can be substituted, but use slightly less.
• 2 g (½ tsp) freshly ground black pepper: Adds a subtle spice and depth of flavor. Freshly ground pepper is always best for its aromatic qualities.
• 2 g (½ tsp) garlic powder: Provides a convenient and consistent garlic flavor throughout the dish. You can substitute with 1-2 cloves of minced fresh garlic, added during the last 5 minutes of roasting to prevent burning.
• 2 g (½ tsp) smoked paprika: This adds a wonderful smoky undertone that complements the roasted flavor of the Brussels sprouts. Sweet paprika can be used if you don’t have smoked paprika, but it won’t have the same depth of flavor.
• 30 g (1 oz) freshly grated Parmesan cheese: Adds a salty, umami-rich flavor that melts beautifully onto the warm Brussels sprouts. Using freshly grated Parmesan is crucial for the best flavor and texture; pre-grated Parmesan often contains cellulose and doesn’t melt as well.
• Zest of 1 lemon (≈1 tsp): Brightens the dish with a refreshing citrus aroma and flavor. Be sure to zest only the yellow part of the lemon peel, avoiding the white pith which can be bitter.
• 15 g (1 Tbsp) toasted sliced almonds, coarsely chopped: Provides a delightful crunch and nutty flavor. Toasting the almonds enhances their flavor and texture.
• 5 g (1 Tbsp) chopped fresh flat‑leaf parsley: Adds a pop of color and a fresh, herbaceous note. Flat-leaf parsley (Italian parsley) is preferred for its flavor, but curly parsley can be used if necessary.
• For lemon vinaigrette: 15 ml (1 Tbsp) lemon juice: Adds a bright acidity to balance the richness of the Parmesan. Freshly squeezed lemon juice is always best.
• For lemon vinaigrette: 15 ml (1 Tbsp) olive oil: Emulsifies with the lemon juice to create a light and flavorful vinaigrette.
• For lemon vinaigrette: ¼ tsp Dijon mustard: Helps to emulsify the vinaigrette and adds a subtle tang.
• For lemon vinaigrette: pinch of salt: Enhances the flavors of the vinaigrette.

How to Achieve Perfectly Crispy Brussels Sprouts: A Step-by-Step Guide

1. Preheat and Prep: Begin by preheating your oven to 200°C (400°F). This high heat is crucial for achieving that desirable crispy exterior. While the oven heats, thoroughly rinse the Brussels sprouts. Don’t skip the drying step! Excess moisture will steam the sprouts instead of roasting them. Trim the ends and halve them lengthwise. Removing any loose or discolored outer leaves ensures a cleaner, more appealing final product.
2. Seasoning is Key: In a large bowl, combine the halved Brussels sprouts with the olive oil, salt, pepper, garlic powder, and smoked paprika. Toss vigorously to ensure every sprout is evenly coated. This even coating is vital for consistent browning and flavor distribution. Don’t be afraid to use your hands to really get in there!
3. Single Layer is Essential: Spread the seasoned Brussels sprouts cut-side down on a rimmed baking sheet. This is *the* most important step for achieving maximum crispiness. Overcrowding the pan will cause the sprouts to steam, resulting in soggy vegetables. Use two baking sheets if necessary.
4. First Roast & Shake: Roast for 20 minutes. The initial roast starts the caramelization process. After 20 minutes, carefully remove the baking sheet from the oven (use oven mitts!). Shake or flip the sprouts to ensure even cooking. This prevents burning on one side and undercooking on the other.
5. Second Roast for Crispness: Return the baking sheet to the oven and continue roasting for another 10-12 minutes. Keep a close eye on them during this stage. You’re looking for deeply browned outer leaves and crispy tips. The exact time will depend on your oven, so adjust accordingly.
6. Parmesan & Lemon Zest Magic: Immediately transfer the hot Brussels sprouts to a large mixing bowl. The heat from the sprouts will melt the Parmesan cheese beautifully. Sprinkle generously with freshly grated Parmesan and lemon zest, then gently toss to coat. Don’t overmix, as you want the cheese to remain slightly textured.
7. Finishing Touches: Add the toasted sliced almonds and chopped fresh parsley. Drizzle the lemon vinaigrette over the top and give a final, gentle toss. The vinaigrette adds a bright, acidic counterpoint to the richness of the Parmesan and the earthiness of the sprouts.
8. Rest & Serve: Let the dish rest for 3 minutes before serving. This allows the flavors to meld together and the sprouts to cool slightly. Plate artfully, as described in the original recipe, for a visually stunning presentation.

Why Cut-Side Down? The Science of Caramelization

Roasting the Brussels sprouts cut-side down maximizes caramelization. When the cut surface directly contacts the hot baking sheet, it creates a Maillard reaction – a chemical reaction between amino acids and reducing sugars that results in browning and a complex, savory flavor. This is the key to achieving those deliciously crispy, slightly charred edges.

The Role of Smoked Paprika: Adding Depth of Flavor

While seemingly subtle, the smoked paprika adds a wonderful layer of complexity to these Brussels sprouts. It introduces a gentle smoky note that complements the natural earthiness of the vegetable and enhances the overall umami profile. Using high-quality smoked paprika is recommended for the best flavor.

Choosing the Right Parmesan: Freshly Grated is Best

Don’t use pre-grated Parmesan cheese! It often contains cellulose and other anti-caking agents that prevent it from melting properly. Freshly grated Parmesan melts beautifully and provides a much more intense, nutty flavor. Parmigiano-Reggiano is the gold standard, but a good quality Grana Padano will also work well.

Troubleshooting: What if My Sprouts Aren’t Crispy Enough?

If your Brussels sprouts aren’t crispy enough, it’s likely due to overcrowding the pan or not using a high enough temperature. Next time, ensure the sprouts are in a single layer and consider increasing the oven temperature slightly (up to 220°C/425°F), but watch them closely to prevent burning. You can also try roasting for a few extra minutes.

Frequently Asked Questions

• Can I use different nuts? Yes! Pecans or walnuts would be delicious substitutes for almonds.
• Can I make this ahead of time? While best served immediately, you can roast the Brussels sprouts ahead of time and reheat them briefly in the oven to crisp them up. Add the Parmesan, lemon zest, and vinaigrette just before serving.
• Is it possible to air fry these? Absolutely! Air frying will yield similar results. Cook at 180°C (350°F) for 12-15 minutes, shaking halfway through.
