Instructions
Preheat the oven to 350°F.
Saute onions in butter over medium-high heat until well caramelized (browned).
Mix ground beef and minced bacon thoroughly, but be careful not to overwork and compress the mixture at any point.
In a separate bowl, lightly whisk together the eggs and all the spices.
Combine eggs, spices, and meats together and mix.
Add bread crumbs and mix until just combined.
Place one half of the meatloaf into a loaf pan, then create a trench in the middle of this half of the meat.
Mix together the caramelized onions and bleu cheese crumbles and pack this mixture tightly into the trench created in the previous step.
Flatten the remaining meat mixture to approximately the size of the top of the loaf pan, then press firmly on top of the filling, trying to seal the edges as best as possible.
Bake in a preheated oven for 1 hour and 30 minutes, or until a probe thermometer placed in the center of the meatloaf reads at least 160°F.
Remove from the oven and allow to rest for 5 minutes before carefully removing it from the loaf pan.
Allow the meatloaf to rest for another 10 minutes before slicing and serving.
