Preheat your oven to 350°F (175°C).

In a large mixing bowl, combine the lean ground beef, breadcrumbs, beaten egg, chopped onion, and diced jalapeños. Mix until well combined.

Add Worcestershire sauce, smoked paprika, salt, and pepper. Stir gently until evenly distributed.

Fold in cream cheese, cheddar cheese, and crumbled bacon until evenly blended.

Transfer the mixture into a greased loaf pan or lined baking sheet. Shape into a loaf.

Bake for 45–50 minutes until golden and internal temperature reaches 160°F (71°C).

Let the meatloaf rest for 5–10 minutes before slicing.

Drizzle warmed ranch dressing over slices before serving.
