Preheat your oven to 375°F and line a small baking dish or loaf pan with parchment paper.
Finely dice the yellow onion so it incorporates easily into the meat mixture.
In a large mixing bowl, combine the ground turkey, egg, almond flour, diced onion, garlic powder, smoked paprika, sea salt, and black pepper.
Gently mix the ingredients by hand until just combined, being careful not to overwork the meat to ensure a tender texture.
Shape the mixture into a compact 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 loaf.
Lay the bacon slices across the top of the loaf, tucking the ends underneath to secure them.
Bake for 25 minutes, then remove from the oven and brush the remaining tablespoon of BBQ sauce over the bacon.
Increase the oven temperature to 400°F and bake for an additional 10 minutes until the bacon is crispy and the internal temperature reaches 165°F.
Allow the meatloaf to rest for 5 minutes before slicing to keep the juices intact.
