A serving spoon lifts a portion of golden, crispy Air Fryer Sloppy Joe Casserole, reminiscent of classic shepherd’s pie, from a white casserole dish.

Air Fryer Sloppy Joe Casserole

Mandy Applegate
Air Fryer Sloppy Joe Casserole is my go-to when I need a dinner that hits every comfort food note and gets on the table fast. Savory ground beef in a tangy ketchup and mustard sauce is topped with fluffy Bisquick biscuit batter and cheddar cheese that bakes up golden and bubbly. Every scoop is saucy, cheesy, and packed with that classic Sloppy Joe flavor everyone loves. I make it for family dinners, potlucks, and game days because it feeds a crowd on a budget and is so much easier than making individual sandwiches. Leftovers keep in the fridge for 3 to 4 days and reheat perfectly in the air fryer.

  • Place the casserole in the air fryer basket and cook for 15 to 20 minutes, or until the top is golden and cooked through. If the top begins to brown too quickly, loosely cover the casserole with aluminum foil during the last few minutes.
  • Garnish with fresh parsley and serve warm.

Notes

Here are a few tips to help you get the best results every time you make your sloppy joe casserole in your air fryer.
  • Drain the beef well: After browning, drain as much fat as you can before adding the ketchup and mustard. Too much fat can make the biscuit layer greasy and stop it from setting properly.
  • Don't skip the simmer: Simmering the beef mixture for the full 5 minutes thickens the filling and intensifies the flavor. If it’s too watery, the biscuit layer can become soggy.
  • Smooth out the batter: Pour the Bisquick batter slowly and spread it gently to cover the beef evenly. If the layer is uneven, some spots may cook less than others.
  • Check your dish size first: Check that your baking dish fits in the air fryer basket before assembling the casserole. If it’s too wide or tall, airflow is blocked, and it won’t cook evenly.
  • Watch the top closely: Air fryers can brown the top quickly. Check at 15 minutes, and if the cheese or biscuit is getting too dark before the center is set, cover it loosely with foil.
  • Flash freeze for easy portions: If you’re freezing leftovers, cut the casserole into portions and place them on a baking sheet for about an hour. This keeps them from sticking together, so you can easily grab just what you need before transferring to containers.
