Before you start
Before beginning, ensure all your ingredients are measured and ready. If you are caramelizing onions from scratch, allow ample time for them to reach a deep, golden brown color and sweet flavor, as this is the foundation of the dish. Preheat your oven to 375 degrees Fahrenheit so it is ready for the meatloaf.
Prepare your loaf pan by lightly greasing it or lining it with parchment paper for easy removal. Ensure your meat thermometer is clean and calibrated, as it is your most important tool for checking the internal temperature of the ground meat.

- 2 lb ground beef
- 1 cup caramelized onions
- 1 cup shredded cheese
Instructions
Mixing the Base
- Prepare the Meatloaf MixtureIn a large mixing bowl, combine the ground beef with the caramelized onions. Mix the ingredients thoroughly until well combined, being careful not to overwork the meat to ensure a tender texture in the final loaf.Look for The mixture should be uniform and well combined.Tip Mixing by hand is the most effective way to ensure the onions are evenly distributed.
The meat and onion mixture should be well-combined but still light in texture. Check that the onions are distributed evenly throughout the beef. The mixture should feel slightly tacky but not overly sticky.
Ensure your hands are clean and the workspace is sanitized before mixing the raw beef, and avoid any cross-contamination with other kitchen surfaces or utensils during this preparation stage.
Baking the Loaf
- Shape and Bake the MeatloafTransfer the meat mixture into a 9x5 inch loaf pan, pressing it down gently to form an even shape. Place the pan in a preheated oven at 375 degrees Fahrenheit and bake until the center reaches a safe internal temperature of 160 degrees Fahrenheit (71 degrees Celsius).Look for The meatloaf should be firm to the touch.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip Use a meat thermometer to check for doneness.
The loaf should be shaped evenly in the pan, with a smooth top. As it bakes, the kitchen will fill with the savory aroma of beef and onions. The meatloaf should shrink slightly from the sides of the pan as it cooks. Ensure the oven temperature remains steady. If you notice the top browning too quickly, you may loosely tent it with a piece of aluminum foil for the remainder of the cooking time.
Adding the Cheese Finish
- Add Cheese and FinishRemove the meatloaf from the oven and carefully top it with the shredded cheese. Return the pan to the oven or use a broiler for a few minutes until the cheese is melted, bubbly, and slightly browned. Let the meatloaf rest for at least 3 minutes before slicing.Look for The cheese should be completely melted and golden.Tip Letting it rest for 10 minutes helps the juices redistribute.
The cheese should be spread evenly over the surface of the cooked loaf. Once back in the oven or under the broiler, watch it closely until the cheese is melted and bubbling. The edges of the cheese may turn a light golden brown. Once it reaches this point, remove it immediately to prevent the cheese from becoming tough or rubbery. Let the loaf rest on a wire rack or cutting board.
Common mistakes
A common mistake is overworking the ground beef mixture, which can lead to a tough or dense texture. Mix just until the ingredients are incorporated. Another error is failing to let the meatloaf rest after baking; slicing too soon causes the juices to escape, leading to a dry result.
Finally, avoid using cheese that is too dry or lacks sufficient moisture, as it may not melt into the desired gooey consistency. Always check the internal temperature, as guessing can lead to undercooked or overcooked meat.
How to tell it’s done
The meatloaf is done when the internal temperature reaches 160 degrees Fahrenheit (71 degrees Celsius) at the thickest part of the loaf. Use a reliable meat thermometer inserted into the center to confirm this. At this temperature, the beef will be fully cooked, safe to consume, and perfectly juicy.
The cheese topping should be fully melted and slightly bubbly, indicating that the final step is complete. Remember to let the meatloaf rest for at least 10 minutes before slicing to ensure the juices settle and the loaf holds its shape.
- Ground meat: 160°F (71°C) in the thickest part
