Directions
Let’s get cooking! Here’s how you whip this dish up in no time:
-
Prepare onions: In a skillet, melt butter over medium heat. Add sliced onions and cook for about 10–12 minutes until they’re golden and caramelized. Transfer to a bowl and set aside.

Shape meatloaf: Form the mixture into a loaf shape and place it in the bottom of the slow cooker.

Add onions & broth: Spread the caramelized onions over the top and around the sides of the meatloaf. Pour beef broth into the bottom of the crockpot (not over the loaf).

Slow cook: Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the internal temperature reaches 160°F (71°C).
