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 turkey, egg, almond flour, finely diced yellow onion, and minced garlic.
Add the sea salt, black pepper, and smoked paprika to the bowl and mix by hand until the ingredients are just incorporated.
Form the turkey mixture into a compact rectangular 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 slice of center-cut bacon lengthwise over the top of the loaf, gently pressing it to adhere.
Bake for 25 to 30 minutes, or until the internal temperature of the meatloaf reaches 160°F.
Remove from the oven, brush the remaining 1 tablespoon of BBQ sauce over the bacon, and broil for 2 minutes until the glaze is bubbly.
Let the meatloaf rest for 5 minutes before slicing to allow the juices to redistribute for a moist texture.
