For the Topping:

Instructions
Cook the Beef: In a large skillet over medium heat, cook the ground beef undisturbed for about 4 minutes or until well browned on one side. Add the minced garlic and chopped onion and cook, breaking the meat up, for 3 to 5 minutes or until the beef is browned and the onions are translucent. Season with salt and pepper to taste. Remove the beef mixture from the skillet and set aside.
Prepare the Sauce and Vegetables: Leave about 1 tablespoon of beef fat in the skillet. Add the butter and let it melt, then stir in the flour and cook for 1 minute, whisking constantly. Slowly pour in the beef stock, whisking until smooth. Stir in the tomato paste and Worcestershire sauce. Bring to a simmer. Stir in the thawed peas and carrots. Cover and let simmer for 4 minutes. Return the beef, onion, and garlic mixture to the skillet and stir to combine. Adjust seasoning if needed.
Assemble: Transfer the mixture to a 7-by-2-inch or 7-by-3-inch round baking pan. Spread the mashed potatoes evenly over the top. Sprinkle with the shredded cheese and sprinkle with a bit of paprika if desired.
Air Fry: Place the dish in an air fryer and cook at 375 F (190 C) for 10 to 12 minutes, or until the cheese is melted and the top is lightly browned.
Serve: Allow the dish to rest for 5 minutes before serving. Garnish with a sprinkle of paprika or chopped parsley.
Notes
If you prefer to use the oven instead of an air fryer:
Preheat the oven to 375 F (190 C).
Assemble the shepherd’s pie as instructed in an oven-safe dish.
Bake uncovered for 25–30 minutes, or until the top is lightly browned and the filling is heated through.
