Since then, it’s been my go-to for potlucks, cozy weekends, and even lazy weeknights when I need a little indulgence with minimal effort.

Recipe Origin or Trivia

What sets this version apart is the boost of flavor from sour cream, cream cheese, and a generous topping of sharp cheddar that forms a rich, bubbly crust. It’s comfort food through and through.

Cooking Tips & Tricks
