½tspblack pepper
Preparation
In a small mixing bowl, stir or whisk all ketchup glaze ingredients (reserving the rest of the minced onion for the meatloaf itself), until combined. Set aside.
Tear off a large strip of heavy-duty aluminum foil, and press it into the bottom and up two of the sides of a 6 quart or larger slow cooker. Spray lightly with non-stick cooking spray, then set aside.
Add ground beef, remaining minced onion (from step 1), stuffing mix, milk, eggs, 2 tablespoons of ketchup glaze, salt, and pepper. Use hands to mix until just combined. Be careful not to over mix.
Shape into an oval-like shape and place into the foil-lined crockpot. Top with ½ cup of the glaze, cover, and cook on Low for 6 hours.
When finished cooking, carefully lift out the meatloaf using the foil overhang, and place it on a baking sheet. Top with ⅔ cup of the glaze and broil until the glaze is sticky and bubbly.
Serve sliced, with remaining glaze sauce on the side for drizzling.
