1-Gathering and Prepping Ingredients: First, preheat the oven to 350 degrees and line a baking sheet with parchment paper for easy cleanup. Puree the mushrooms until fine and crush the buttery crackers, then cube the cheddar cheese into quarters. These prep steps help mix everything evenly without any hassle.

2-Mixing and Forming the Meatballs: In a large bowl, combine the pureed mushrooms, ground beef, crushed crackers, yellow mustard, ketchup, Worcestershire sauce, black pepper, onion powder, garlic powder, and the large egg. Mix everything with clean hands until well incorporated, but don’t overmix to keep the meat tender. Form the mixture into 12 large meatballs, creating a small depression in each one to hold the cheese.

3-Stuffing and Baking: Place 1 to 3 cubes of cheddar cheese into each depression and cover completely with the meat mixture, making sure no holes remain to prevent leaking. Arrange the meatballs on the prepared baking sheet and bake for 30 minutes until fully cooked. Let them rest for a few minutes before serving to lock in the juices for a juicy twist, consider pairing with a simple apple crisp side from our collection of easy desserts.
