1-Step 1: Prepare Your Oven and Baking Sheet Preheat your oven to 350°F. This temperature allows the meatloaf to cook evenly without drying out the exterior before the center is done. Line a rimmed baking sheet with parchment paper or aluminum foil. The lining makes cleanup easy and prevents the meatloaf from sticking to the pan. A rimmed baking sheet is ideal because it allows hot air to circulate around the loaf, creating those delicious crispy edges on all sides. If you prefer using a loaf pan, line it with parchment paper, leaving some overhang on the sides. This makes removing the meatloaf much easier after baking. For loaf pans, increase the oven temperature to 375°F since the meat is more compact and needs slightly higher heat to cook through.

2-Step 2: Sauté the Onions Heat 1 teaspoon of oil in a skillet over medium heat. Add the finely chopped onion and cook for 5-7 minutes until softened and golden. This step is crucial because raw onions can create pockets of sharp, harsh flavor in the finished meatloaf. Sautéing releases the natural sugars in the onions and creates a sweeter, more mellow taste that blends seamlessly with the beef. Once the onions are cooked, transfer them to a plate and let them cool completely. Adding hot onions to the raw meat mixture could partially cook the eggs and change the texture of your meatloaf. While the onions cool, you can measure out and prepare the remaining ingredients.

3-Step 3: Mix the Meatloaf Ingredients In a large mixing bowl, combine the cooled sautéed onions with all the meatloaf ingredients: 2 pounds ground beef, 1 teaspoon salt, 2 large eggs, 3 minced garlic cloves, 2 tablespoons ketchup, 3 tablespoons chopped fresh parsley, 3/4 cup Panko breadcrumbs, 1/3 cup milk, 1 teaspoon Italian seasoning, and the black pepper. Mix everything together with your hands until just combined. This is an important tip: avoid overmixing. Working the meat too much compacts the proteins and creates a dense, tough texture. You want the ingredients evenly distributed but not overly processed. A minute or two of gentle mixing should be sufficient. The mixture should hold together when shaped but still have a relatively loose texture.

4-Step 4: Shape the Meatloaf Transfer the meat mixture to your prepared baking sheet. Shape it into a loaf approximately 8 inches long, 4 inches wide, and 3 inches tall. Use your hands to create smooth, even sides, and pat the top slightly flat. This free-form shape allows heat to circulate around all sides, creating more crispy edges and faster, more even cooking than a loaf pan. Don’t pack the meat too tightly when shaping. A looser shape creates a more tender meatloaf. If you notice any large air pockets, gently press them out, but don’t compress the meat excessively.

5-Step 5: Bake the Meatloaf Place the shaped meatloaf in the preheated oven and bake uncovered for 40 minutes. During this initial baking period, the meatloaf sets and begins cooking through. The exterior will start to brown slightly, and some fat may render out onto the baking sheet. While the meatloaf bakes, prepare the sauce by mixing the ketchup, white vinegar, brown sugar, garlic powder, and onion powder in a small bowl. Stir until smooth and well combined.

6-Step 6: Add the Sauce and Finish Baking After 40 minutes, remove the meatloaf from the oven. Spread the prepared sauce evenly over the top and sides of the meatloaf. The sauce adds moisture, creates a beautiful glaze, and brings sweet and tangy flavor notes that complement the savory meat. Return the meatloaf to the oven and bake for an additional 20 minutes. The sauce will caramelize and create that signature meatloaf glaze everyone loves. The meatloaf is done when it reaches an internal temperature of 160°F in the thickest part. Use a meat thermometer for accuracy, as visual cues alone can be misleading with ground meat.

7-Step 7: Rest and Serve Once the meatloaf reaches the proper temperature, remove it from the oven and let it rest for 10-15 minutes before slicing. This resting period allows the juices to redistribute throughout the meat rather than running out when you cut into it. Skipping this step results in drier meatloaf and a messy cutting board. After resting, slice the meatloaf into thick portions and serve with your favorite sides.
