Step 1

Line the insert of a 6-quart slow cooker with aluminum foil and spray with cooking spray.

Step 2

In a medium bowl, combine the ground beef, bell pepper, onion, eggs, salt, cracker crumbs, and ¾ cup of the ketchup. Use a spoon or your hands to mix until the ingredients are incorporated.

Step 3

Shape the meat mixture into a loaf and place it in the slow cooker.

Step 4

Cover and cook on Low for 6 to 8 hours or on High for 3 to 4 hours, until the meat is no longer pink.

Step 5

In the last 15 minutes of cooking, in a small bowl, mix together the remaining ketchup, mustard, and brown sugar and spread on top of the meat loaf. Cook for the remaining 15 minutes.

Step 6

Let cool. Slice and serve with fresh thyme.
