Preheat your oven to 375°F and line a small baking dish with parchment paper for easy cleanup.
In a large mixing bowl, combine the ground beef, almond flour, egg, finely diced yellow onion, minced garlic, sea salt, black pepper, and smoked paprika.
Gently mix the ingredients by hand until just incorporated, being careful not to overwork the meat to ensure a tender texture.
Shape the mixture into a uniform loaf and place it in the center of the prepared baking dish.
Brush 1 tablespoon of the sugar-free BBQ sauce evenly over the top and sides of the meatloaf.
Lay the bacon slices over the top of the loaf, tucking the ends underneath to secure them.
Bake for 30 minutes, then remove from the oven and brush the remaining 1 tablespoon of BBQ sauce over the bacon.
Return the meatloaf to the oven for an additional 10 to 15 minutes until the bacon is crisp and the internal temperature reaches 160°F.
Allow the meatloaf to rest for 5 minutes before slicing to keep the juices intact.
