Creating this mouthwatering Jalapeno Popper Stuffed Meatloaf is a straightforward process. Follow these steps for an incredible outcome:

1. Preheat Oven: Preheat your oven to 350°F (175°C).

2. Prepare the Filling: In a medium bowl, combine the cream cheese, diced jalapenos, and half of the cheddar cheese. Mix until well combined and set aside.

3. Sauté Onions and Garlic: In a skillet over medium heat, sauté the onions until soft, about 5 minutes. Add minced garlic and cook for another minute until fragrant. Remove from heat and let cool slightly.

4. Mix the Meatloaf Mixture: In a large mixing bowl, combine the ground beef, breadcrumbs, eggs, Worcestershire sauce, salt, pepper, smoked paprika, and the sautéed onions and garlic. Mix until just combined.

5. Form the Meatloaf Base: On a large piece of parchment paper or wax paper, form half of the meat mixture into a rectangle, about 1 inch thick.

6. Add Filling: Spread the jalapeno and cream cheese mixture evenly over the meatloaf base, leaving about an inch border around the edges.

7. Roll the Meatloaf: Carefully lift the parchment paper to roll the meatloaf, starting from the long side, until it forms a log shape. Pinch the seams to seal, ensuring the filling stays inside.

8. Place in Baking Dish: Transfer the rolled meatloaf to a baking dish or a lined rimmed baking sheet. Optionally, slather the top with ketchup for extra flavor.

9. Bake: Place the meatloaf in the preheated oven and bake for about 1 hour, or until the internal temperature reaches 160°F (71°C).

10. Rest Before Slicing: Remove from the oven and let the meatloaf rest for 10-15 minutes before slicing. This allows the juices to redistribute and makes for easier serving.
