Preheat the oven to 350 degrees Fahrenheit. Line a sheet pan with foil paper and set it aside.
Place the crackers in a large bowl and use your hands and crush them into small pieces. Pour the beef broth over the crackers. Set aside for about 5 minutes.
Add the diced onion, bell pepper, egg, ketchup, Worcestershire sauce, garlic powder, paprika, salt, black pepper, and beef to the bowl. Use clean or gloved hands and stir the mixture until thoroughly combined. Be careful not to overmix the mixture. Mixing the beef mixture too much can lead to a tough meatloaf.
Place the meat mixture onto the sheet pan and form an oval loaf.
Bake meatloaf in preheated oven for about 50 minutes to 1 hour. You'll need the inside of the meatloaf to reach an internal temperature of 165 degrees Fahrenheit.
When there are about 15 minutes left on the meatloaf, create the glaze by combining ketchup and brown sugar in a small bowl. Brush this mixture over the meatloaf and allow the meatloaf to finish baking.
Once the meatloaf is done baking, remove it from the oven and allow it to cool for 10 minutes. Then slice the meatloaf and serve.
