I use my stand mixer with the paddle attachment to mix the ground meats with the onion, garlic, eggs, crackers, ketchup, ¼ C of the BBQ sauce, Worcestershire sauce, and brown mustard until well combined. Set aside.
Prepare the peach sauce by heating the preserves in the microwave or on the stovetop until they become pourable, about 30 seconds to 1 minute. Remove from heat and stir in the brown sugar and remaining ¼ C of BBQ sauce until well combined."
Line a loaf pan with plastic wrap, then layer with bacon slices and a generous coating of the peach sauce.
Press the meat mixture into the pan, then gently turn it out onto a foil-lined* rack set over a baking sheet. *poke a few holes through the foil so the fat can drain onto the sheet pan.
Place it on the middle rack of the oven and bake for 1 hour or until cooked through. The meatloaf should register 160℉. If you want the bacon and sauce to be sticky and caramelized on top, broil for 1-2 minutes. Allow it to rest for 10 minutes before slicing.
