In a large mixing bowl, combine lean ground beef, breadcrumbs, beaten egg, finely chopped onion, and diced jalapeños. Stir in Worcestershire sauce, smoked paprika, salt, and pepper. Gently fold in cream cheese, shredded cheddar cheese, and crumbled bacon until just combined.

Preheat your oven to 350°F (175°C). Transfer the mixture into a greased loaf pan or shape into a loaf on a foil-lined baking sheet. Bake for 45-50 minutes or until internal temperature reaches 160°F.

Let the meatloaf rest for 5-10 minutes to allow juices to redistribute. Slice into portions.

Warm the ranch dressing in a small saucepan over low heat until pourable. Drizzle over each slice just before serving.
