In a large mixing bowl, combine ground beef, breadcrumbs, and beaten egg, mixing until evenly distributed. Add onion, jalapeños, Worcestershire sauce, smoked paprika, salt, and pepper.

Gently fold in cream cheese, shredded cheddar cheese, and crumbled bacon until evenly distributed.

Preheat oven to 350°F (175°C). Shape the meat mixture into a loaf and place it in a greased loaf pan. Bake for 45-50 minutes until the internal temperature reaches 160°F (70°C).

Remove from oven and let it rest for 5-10 minutes. Warm ranch dressing gently in a small saucepan.

Drizzle ranch over meatloaf slices before serving.
