FAQs: - What is the total time from start to table? About 25 minutes including preheating, cooking, and the 3 minute rest for the pork. - Can I freeze leftovers and reheat them later? Freeze pork separately for up to 2 months. Vegetables soften when frozen, so refrigerate those up to 3 days. Reheat in the air fryer at 350 degrees Fahrenheit until the pork is hot throughout, 165 degrees Fahrenheit. - Why do I need to flip the food halfway through cooking? Flipping ensures even heat exposure, better browning, and a crisp-tender texture without overcooking.

Ingredients

• 1 pound pork tenderloin, trimmed and cut into 3/4 inch cubes
• 8 ounces fresh green beans, trimmed and halved
• 1 medium red bell pepper, sliced into 1/2 inch strips (about 5 ounces)
• 1 tablespoon plus 1/2 tablespoon extra virgin olive oil, divided
• 1/3 cup finely grated Parmesan cheese
• 3 garlic cloves, minced
• 1 teaspoon lemon zest
• 1 teaspoon Italian seasoning
• 1 teaspoon smoked paprika
• 1 teaspoon kosher salt, divided
• 1/2 teaspoon black pepper
• 1/4 teaspoon crushed red pepper flakes, optional
• 2 tablespoons chopped fresh parsley, for garnish
• Lemon wedges, for serving

Instructions

1. Preheat the air fryer to 400 degrees Fahrenheit for 5 minutes.
2. Season the pork: In a bowl, toss pork cubes with 1 tablespoon olive oil, half the minced garlic, lemon zest, Italian seasoning, smoked paprika, 1/2 teaspoon salt, and black pepper.
3. Season the vegetables: In another bowl, toss green beans and bell pepper with 1/2 tablespoon olive oil, remaining garlic, the remaining 1/2 teaspoon salt, and half of the Parmesan. Reserve the rest of the Parmesan.
4. Load the air fryer. For a dual basket unit, place pork in one basket and vegetables in the other in single layers. For a single basket, cook pork first, then vegetables, or cook in two batches to avoid crowding.
5. Air fry the pork at 400 degrees Fahrenheit for 8 to 10 minutes, shaking or flipping halfway. Use a digital meat thermometer to confirm the pork reaches 145 degrees Fahrenheit. Transfer to a plate and rest for 3 minutes.
6. Air fry the vegetables at 400 degrees Fahrenheit for 9 to 11 minutes, shaking halfway, until crisp tender with browned edges.
7. Combine: Return pork to the basket with vegetables for 1 minute to warm together if desired. Toss with the remaining Parmesan and parsley. Serve with lemon wedges.
