What Ingredients You Will Need

This recipe uses straightforward, wholesome ingredients that work together to create bold flavor and delightful texture without any fuss. Most are pantry staples or fresh produce you can find year-round.

• Brussels sprouts: About 1 pound (450 g), trimmed and halved (small to medium size works best for smashing)
• Olive oil: 2 tablespoons (extra virgin for best flavor)
• Parmesan cheese: ¼ cup (25 g), finely grated (I prefer Parmigiano-Reggiano for its nutty depth)
• Lemon: 1 medium, juiced and zest reserved
• Garlic powder: ½ teaspoon (adds subtle savory notes)
• Salt: ½ teaspoon, or to taste (sea salt flakes if you have them for texture)
• Black pepper: Freshly ground, ¼ teaspoon
• Optional red pepper flakes: A pinch for a little heat (totally optional but recommended if you like a kick)

Ingredient tips: Look for firm Brussels sprouts with tight leaves—avoid any that look wilted or yellowing. If fresh lemons aren’t around, a splash of good-quality bottled lemon juice works fine, but fresh is always tastier. If you want a dairy-free version, swap Parmesan for a sprinkle of nutritional yeast.

Equipment Needed

• Air fryer: Essential for that crispy texture; a 3 to 5-quart size works perfectly. If you don’t have one, a convection oven is a workable alternative.
• Mixing bowl: Medium size, for tossing Brussels sprouts with oil and seasoning.
• Baking sheet or sturdy plate: For smashing the sprouts (a flat surface like a cutting board works too).
• Potato masher or heavy-bottomed glass: To gently smash the sprouts without turning them to mush.
• Microplane or fine grater: For zesting the lemon and grating Parmesan.
• Tongs or spatula: For flipping the sprouts halfway through cooking.

Personally, I started with a simple potato masher I found at a thrift store — it didn’t cost a thing and worked like a charm! If you’re on a budget, you can even use the bottom of a sturdy glass, just watch your fingers. Keeping your air fryer clean is a must; a quick wipe after each use keeps it running smoothly and tasting fresh.

Preparation Method

1. Prep the Brussels sprouts: Rinse about 1 pound (450 g) of Brussels sprouts under cold water. Trim the stem ends and slice each sprout in half lengthwise. Pat dry thoroughly with a clean towel to avoid sogginess.
2. Smash the sprouts: Place the halved sprouts cut-side down on a baking sheet or sturdy plate. Using a potato masher or the bottom of a heavy glass, gently press down on each sprout until it’s flattened but still holds together. You want them smashed enough to increase crispy surface area, but not so hard they fall apart.
3. Season: Transfer the smashed sprouts to a mixing bowl. Drizzle with 2 tablespoons (30 ml) of extra virgin olive oil, then sprinkle ½ teaspoon garlic powder, ½ teaspoon salt, ¼ teaspoon freshly ground black pepper, and a pinch of red pepper flakes if using. Toss gently to coat evenly.
4. Preheat air fryer: Set your air fryer to 375°F (190°C) and let it warm up for about 3 minutes. This step helps ensure even cooking and crispiness.
5. Air fry: Arrange the seasoned sprouts in a single layer in the air fryer basket, cut side up if possible, making sure they don’t overlap. Cook for 12-15 minutes, flipping halfway through (at about 7 minutes) to get an even golden crust. Look for deep golden edges and a nutty aroma as your cue.
6. Add Parmesan and lemon: When the sprouts are crispy and tender, transfer them to a serving bowl. While still hot, toss with ¼ cup (25 g) finely grated Parmesan cheese, the zest of 1 lemon, and juice of half to a whole lemon (to taste). Stir gently to combine.
7. Serve immediately: For best texture and flavor, serve your crispy air fryer smashed Brussels sprouts right away. If you want, sprinkle a bit more Parmesan or lemon zest on top for a fresh pop.

Tip: If your air fryer basket is small, cook in batches to avoid overcrowding, which can steam the sprouts instead of crisping them. Also, don’t rush the smashing step—gentle pressure is key!

Cooking Tips & Techniques

Getting Brussels sprouts crispy without turning them bitter or mushy can be tricky, but here’s what I’ve learned:

• Dry sprouts are happy sprouts: Make sure to pat the Brussels sprouts dry thoroughly after washing; moisture is the enemy of crispiness.
• Don’t skip smashing: This step may seem odd, but it’s the magic behind that golden crust. It exposes more surface area for the oil and heat to work on.
• Oil choice matters: I stick with extra virgin olive oil for flavor, but avocado oil is great too if you want a higher smoke point.
• Flip halfway: Turning them at about the 7-minute mark helps them brown evenly without burning.
• Avoid overcrowding: Crowding the basket traps steam and results in limp sprouts. Give them space to crisp up properly.
• Use fresh lemon juice: Adding lemon after cooking brightens the dish without cooking off the freshness.
• Parmesan timing: Toss with cheese right after cooking to melt it slightly without burning.

Once, I forgot to flip the sprouts and ended up with one side almost burnt and the other barely cooked. Not a disaster, but definitely a lesson learned! Now, I set a timer as a reminder. Also, multitasking while air frying works well—use the cook time to prep other dishes or clean up.

Variations & Adaptations

This recipe is pretty flexible, which makes it fun to customize:

• Dietary swaps: For a vegan twist, swap Parmesan with nutritional yeast or a plant-based cheese alternative. Use dairy-free olive oil spread if you want more richness.
• Seasonal flavors: In fall, try adding a sprinkle of smoked paprika or a dash of maple syrup before air frying for a sweet-smoky note.
• Spice it up: Add a pinch of cayenne pepper or chili powder to the seasoning mix if you like it spicy.
• Cooking method: No air fryer? Roast smashed sprouts on a baking sheet at 425°F (220°C) for about 20-25 minutes, flipping halfway.
• My personal favorite: I once tossed in some toasted pine nuts and fresh thyme after cooking—unexpected but delightful! The crunch and herbaceous hint took it to another level.

Serving & Storage Suggestions
