Ingredients

• Pork belly, skinless, 8 oz (225 g), cut into 1/2 inch cubes
• Brussels sprouts, 16 oz (450 g), trimmed and halved
• Extra-virgin olive oil, 1 1/2 tablespoons
• Grated Parmesan cheese, 2 tablespoons
• Garlic powder, 1 teaspoon
• Smoked paprika, 1 teaspoon
• Kosher salt, 3/4 teaspoon, divided
• Freshly ground black pepper, 1/2 teaspoon
• Apple cider vinegar, 2 teaspoons
• Lemon zest, 1 teaspoon, optional
• Red pepper flakes, 1/4 teaspoon, optional

Instructions

1. Preheat the air fryer to 400 degrees Fahrenheit. This high heat promotes fast rendering and crispy edges.
2. Pat the pork belly dry. Toss with 1/2 tablespoon olive oil, 1/4 teaspoon salt, half the garlic powder and paprika, and a pinch of pepper.
3. Arrange pork belly in a single layer in the basket. Air fry 10 to 12 minutes, shaking halfway, until the pork reaches at least 145 degrees Fahrenheit. Confirm with a digital meat thermometer. Transfer to a plate and rest 3 minutes. For extra crisp and rendering, you may cook to 185 to 200 degrees Fahrenheit before resting.
4. While the pork rests, toss Brussels sprouts with remaining 1 tablespoon olive oil, 1/2 teaspoon salt, remaining garlic powder and paprika, black pepper, and red pepper flakes if using.
5. Add Brussels sprouts to the basket. Air fry at 380 degrees Fahrenheit for 10 minutes, shaking once.
6. Return the rested pork belly to the basket with the sprouts. Air fry 5 to 7 minutes more at 380 degrees Fahrenheit, until sprouts are browned with charred edges and pork belly is deeply crisp.
7. Transfer to a bowl. Sprinkle Parmesan, drizzle apple cider vinegar, and add lemon zest. Toss and adjust salt and pepper to taste. Serve hot.
