Preheat the oven to 350°f, crushing up the saltine crackers, and dicing the onion and bell pepper.
In a mixing bowl, combine the crackers, onion, bell pepper, eggs, milk, minced garlic, Worcestershire and browning sauce, ketchup, kosher salt, black pepper, and onion powder.
Add the ground beef to the same bowl and mix the meatloaf ingredients together until thoroughly combined and evenly distributed.
Transfer the mixture to a loaf pan and press firmly to ensure everything sticks together well during baking.
Place the meatloaf in the oven and bake for 45 minutes.
in a small mixing bowl, whisk together the Ketchup, dark brown sugar, Dijon mustard, and Worcestershire sauce to prepare the meatloaf glaze.
Once you have reached the 45-minute mark, remove the meatloaf from the oven, drain any excess grease if you’d like, and brush the top with the glaze.
Place your meatloaf back in the oven and bake for about another 45 minutes, or until the internal temperature reaches 160°F.
Once the meatloaf is done, let it rest for about 10 minutes, slice it, and serve it with brown gravy, mashed potatoes, or any of your favorite comfort-food sides.
