Preparation: Begin by preheating your oven to 350 degrees Fahrenheit. Prepare a baking sheet by lining it with parchment paper or aluminum foil for easy cleanup.
Mixing the Ingredients: In a substantial mixing bowl, combine the ground beef, finely diced onion, green bell pepper, eggs, kosher salt, black pepper, drained diced tomatoes, and crushed Ritz crackers. Employ either your hands or a large wooden spoon to mix the ingredients until just combined, taking care not to overmix to maintain the tenderness of the loaf.
Forming the Loaf: Transfer the mixed ingredients onto the prepared baking sheet. Use your hands to mold the mixture into a compact, uniform loaf shape, ensuring an even thickness throughout to promote consistent cooking.
Initial Baking: Place the meatloaf in the preheated oven and bake for 30 minutes. After this initial cooking period, remove the meatloaf from the oven.
Applying the Glaze: Utilize a pastry brush to evenly spread the ketchup over the top and sides of the partially cooked meatloaf. This layer will contribute a tangy flavor and appealing glaze upon further baking.
Final Baking: Return the meatloaf to the oven and continue to bake for an additional 30 minutes, or until the internal temperature reaches 165 degrees Fahrenheit, ensuring that the meat is fully cooked and safe to eat.
Resting: After baking, allow the meatloaf to rest at room temperature for 10 minutes before slicing. This resting period lets the juices redistribute throughout the meatloaf, resulting in a moister and more flavorful final product.
