2 tbsp butter

1 tsp onion powder

Tips & Variations

For extra flavor, try adding sautéed mushrooms or caramelized onions to the beef mixture.

Use cheddar or a blend of cheeses for a different taste and texture.
Swap ground beef for ground turkey or chicken for a leaner option.
If you prefer, use brown rice instead of white rice for added fiber.
