Prepare the Meatloaf Mixture:

• Preheat your oven to 350°F (175°C).

• In a large mixing bowl, beat the eggs. Add the milk and crushed Ritz crackers, stirring until well combined.

• Mix in the chopped onion and shredded cheddar cheese.

• Add the ground beef, salt, and black pepper to the bowl. Mix gently until all ingredients are evenly incorporated. Avoid overmixing to keep the meatloaf tender.

Shape and Bake:

• Shape the meat mixture into a loaf and place it on a baking sheet lined with aluminum foil for easy cleanup.

• Bake in the preheated oven for 45 minutes.

Prepare the Topping:

• While the meatloaf is baking, combine the ketchup, brown sugar, and mustard in a small bowl, mixing until smooth.

Glaze and Continue Baking:

• After the initial 45 minutes of baking, remove the meatloaf from the oven. Spread half of the prepared topping evenly over the top of the meatloaf.

• Return the meatloaf to the oven and bake for an additional 10 minutes.

• After 10 minutes, apply the remaining topping and bake for another 5-10 minutes, or until the meatloaf reaches an internal temperature of 160°F (71°C).

Rest and Serve:

• Once done, remove the meatloaf from the oven and let it rest for about 10 minutes. This allows the juices to redistribute, making for a moister meatloaf.

• Slice and serve warm.
