How to make the best CrockPot meatloaf - This simple and easy slow cooker recipe makes a delicious and healthy dinner with a combination of ground beef and turkey and a packet of onion soup mix.
This step is optional but adds a lot of flavor. Heat the butter in a small skillet over medium-high heat. Add the onion and sauté until the onions are soft and beginning to brown.
In a large bowl, mix everything except ketchup and A-1 Sauce together. Don't be afraid to use your hands. Form the mixture into a loaf in the bottom of your crockpot.
Mix the ketchup and A-1 Sauce in a small bowl. Spread on top of the meatloaf.
Cover and cook on high 2½ hours or on low 5 hours.
Meatloaf is done when the internal temperature reaches 165ºF on a meat thermometer. Note that this is higher than a typical beef temperature, but you've included ground turkey, which needs to be cooked to a higher temperature in order to be safely consumed.
