Step‑by‑Step Instructions for Onion Soup Meatloaf
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This initial step is crucial as it ensures your Onion Soup Meatloaf bakes evenly and thoroughly. While the oven warms up, gather your mixing bowl, spatula, and all the ingredients so you’re ready to create this comforting dish.
Step 2: Mix the Base Ingredients
In a large mixing bowl, combine the onion soup mix, eggs, water, and 1/3 cup of ketchup. Stir the mixture until all ingredients are well blended, creating a smooth base. The egg will help bind everything together, ensuring a tender meatloaf. Set this flavorful mixture aside as you prepare for the next step.
Step 3: Add the Meat and Crumbs
Carefully incorporate the ground beef and bread crumbs into the mixture. Using your hands or a spatula, mix gently until everything is combined but be cautious not to overwork the meat. This is key to keeping your Onion Soup Meatloaf nice and tender. Once mixed, form the mixture into a loaf shape.
Step 4: Prepare the Loaf Pan
Lightly grease a loaf pan with cooking spray or a drizzle of oil to prevent sticking. Place your shaped onion soup meatloaf inside the pan, pressing it gently to fit the edges. By ensuring a snug fit, you’ll prevent the meatloaf from cracking as it bakes.
Step 5: Bake to Perfection
Slide the loaf pan into your preheated oven and bake for 1 hour and 15 minutes. Start checking for doneness at the 1-hour mark by inserting a meat thermometer into the center; the internal temperature should read 165°F. The meatloaf should be firm to the touch and have a rich golden-brown color on top.
Step 6: Make the Glaze
While the meatloaf bakes, prepare the glaze by combining 1 cup of ketchup, brown sugar, and ground mustard in a saucepan. Cook this mixture over medium heat, stirring until it’s smooth and well blended. The sweetness will complement the savory flavors of the meatloaf perfectly and add a delicious finish.
Step 7: Glaze and Rest
Once the meatloaf is fully baked, carefully remove it from the oven and generously brush the glaze over the top. Return the meatloaf to the oven for an additional 15 minutes, allowing the glaze to caramelize beautifully. After baking, let the meatloaf rest for 10-15 minutes before slicing, which helps retain its juices for a succulent bite.
Step 8: Slice and Serve
When it’s time to serve, slice the Onion Soup Meatloaf into thick pieces with a sharp knife. The beautiful glaze will glisten, revealing the tender interior. Pair your hearty meatloaf with your favorite sides, such as creamy mashed potatoes or a light salad, for a well-rounded meal the whole family will love.
