Heat olive oil in a large skillet over medium-high heat. Season chicken pieces generously with salt, black pepper, garlic powder, and paprika, then add to the hot oil. Cook for 6-8 minutes per side until golden brown, stirring occasionally to ensure even coloring throughout the cozy game day appetizer recipe.
Remove chicken from the skillet and set aside on a plate. In the same skillet, add diced onions and bell peppers, sautéing over medium heat for 5-7 minutes until softened and fragrant. Stir occasionally to prevent sticking and encourage even cooking of the vegetables.
Return chicken to the skillet with the vegetables. Pour chicken broth and Worcestershire sauce over top, then reduce heat to medium-low and simmer for 10-12 minutes until the liquid reduces slightly. This step allows flavors to meld beautifully in your warm appetizer.
In a small bowl, combine cream cheese, sour cream, and shredded cheddar cheese until smooth and well-blended. Slowly stir this creamy mixture into the skillet with chicken and vegetables, folding gently to combine. Cook for 3-4 minutes until the sauce thickens and coats everything evenly without breaking.
Taste and adjust seasonings as needed with additional salt or paprika. Transfer the warm mixture to a serving dish and top with breadcrumbs mixed with fresh parsley for texture and visual appeal. Serve immediately while steaming hot for maximum comfort and coziness.
