Season the pork chops generously on both sides with salt, black pepper, garlic powder, and smoked paprika.
Brush the pork chops with 2 teaspoons of olive oil.
Preheat your air fryer to 400°F (200°C) for 3-5 minutes.
Place the seasoned pork chops in the air fryer basket in a single layer. Cook for 10-12 minutes, flipping halfway through, until golden brown and cooked through.
While chops cook, heat 1/4 cup olive oil in a skillet over medium heat. Add sliced onion and cook until softened and lightly browned, about 5-7 minutes.
Add sliced mushrooms and minced garlic to the skillet with the onions. Cook for another 5-7 minutes until mushrooms are tender and browned.
Reduce heat to low, and stir in about 1/2 cup of water or broth (optional, for extra gravy). Let it simmer for 2-3 minutes until slightly thickened.
Once pork chops are done, carefully place them into the mushroom and onion mixture in the skillet. Spoon the gravy over the pork chops. Let it simmer for 1-2 minutes for the flavors to meld.
