Preheat your oven to 350°F. Lightly grease a 9×13-inch casserole dish and set it aside.

Dice the onion and set aside.

Add the ground beef and diced onion to a large skillet. Season with salt and pepper, then cook over medium heat, breaking up the meat as it cooks, until the beef is fully browned. Drain off any excess grease.

While the beef cooks, cut the biscuits into quarters. Place them in a bowl and toss with 1 cup of the shredded cheese until evenly coated.

Add the sloppy joe sauce to the cooked beef mixture and stir until well combined. Gently fold in the biscuit and cheese mixture.

Transfer the mixture into the prepared casserole dish and spread evenly, then sprinkle the remaining cup of cheese over the top.

Bake for 30 minutes, or until the biscuits are cooked through and the cheese is melted and bubbly.

Remove from the oven and serve warm.
