This slow cooker meatloaf is incredibly tender, moist, and flavorful, making it a perfect weeknight meal with minimal effort. The slow cooking process ensures it's never dry!
In a large bowl, combine ground beef, bread crumbs, milk, egg, chopped onion, 2 tablespoons of ketchup, Worcestershire sauce, salt, and pepper. Mix gently until just combined. Do not overmix.
Shape the mixture into a loaf and place it in a greased slow cooker.
In a small bowl, whisk together the glaze ingredients: 0.5 cup ketchup, brown sugar, and apple cider vinegar.
Pour the glaze evenly over the meatloaf.
Cover and cook on low for 3.5 to 4 hours, or on high for 2.5 to 3 hours, until the internal temperature reaches 160°F (71°C).
Let the meatloaf rest for 10 minutes before slicing and serving.
Notes
