Preheat oven to 375°F (190°C) and line or grease a loaf pan.
Gently mix ground beef, ground pork, paprika, garlic powder, onion powder, breadcrumbs, eggs, salt, and pepper until just combined.
Stir together cream cheese, shredded cheddar, chopped jalapeños, and crumbled bacon for the filling.
Press half the meat mixture into the pan, add the cheesy filling, then top with remaining meat, sealing the edges.
Bake 45–55 minutes until internal temperature reaches 160°F; let rest 10 minutes before slicing.
Mix ranch dressing, sour cream, and optional lime or herbs; drizzle over slices before serving.
