Step-by-Step: How to Make Onion Soup Meatloaf

Creating this savory Lipton onion soup meatloaf is a breeze, coming together in just 3 simple steps. You’ll be amazed at how quickly you can prepare a dish that tastes like it took hours. For the full, printable recipe and precise measurements, be sure to scroll down to the recipe card at the bottom of this post.

• 1. Prepare Your Workspace & Combine Ingredients: First, preheat your oven to 350°F (175°C) and line a baking sheet with aluminum foil for easy cleanup. In a large mixing bowl, add your ground beef, beaten eggs, a packet of onion soup mix, breadcrumbs, water, and 1/3 cup of ketchup. Use your hands or a sturdy spoon to gently fold and mix all the ingredients together. Be careful not to overmix, as this can lead to a tough meatloaf. Mix just until everything is evenly combined and no dry spots remain.
• 2. Shape the Loaf & Initial Glaze: Transfer the seasoned meat mixture onto your prepared foil-lined baking sheet. Using your hands, gently shape the mixture into a uniform loaf. Aim for an even thickness throughout the loaf (approximately 8-9 inches long and 4-5 inches wide) to ensure it bakes evenly. Once shaped, brush the top surface of the meatloaf lightly with a small amount of ketchup. This initial layer begins to caramelize, adding to the meatloaf’s savory crust.

• 3. Bake to Perfection & Rest: Place the meatloaf in your preheated 350ºF oven and bake for approximately 1 hour. After this initial baking period, carefully remove the meatloaf from the oven. Brush the top generously with additional ketchup, creating a thicker, more vibrant glaze. Return it to the oven and continue baking for another 15 minutes, or until the internal temperature reaches 160ºF (71°C) when checked with a meat thermometer. Once baked, remove the meatloaf from the oven and let it rest for at least 5-10 minutes. This crucial resting period allows the juices to redistribute throughout the loaf, resulting in a much juicier and more tender end product, as well as cleaner slices. Then, slice and serve your delicious homemade meal!

Expert Tips and Delicious Variations

Achieving the perfect, juicy meatloaf is simple with a few key tips and tricks. Plus, don’t be afraid to get creative with these variations to customize your meal!

• Avoid Overmixing the Meat: This is perhaps the most important tip for a tender meatloaf. Just like with meatballs or burgers, overworking the ground meat mixture can activate proteins, leading to a dense, rubbery, and tough meatloaf. Mix gently and only until the ingredients are just combined and no dry streaks are visible.
• Always Check for Doneness: While this meatloaf typically bakes in about 1 hour and 15 minutes, oven temperatures can vary. The most accurate way to determine if your meatloaf is done is by checking its internal temperature with an instant-read meat thermometer. Insert the thermometer into the thickest part of the loaf. Meatloaf is safely cooked when it reaches an internal temperature of 160ºF (71°C).
• The Essential Resting Period: Similar to resting a steak or any cooked protein, allowing the meatloaf to rest for at least 5-10 minutes after baking is crucial. This allows the internal juices, which have migrated to the center during cooking, to redistribute evenly throughout the loaf. The result is a much juicier, more flavorful meatloaf and ensures cleaner, neater slices when you cut it.
• Swap Water for Milk for Richness: This recipe uses water to add moisture to the meat mixture, keeping it juicy. If you prefer a richer, slightly creamier texture and flavor, you can easily substitute the water with an equal amount of milk (dairy or non-dairy). This can add another layer of depth to your meatloaf.
• Add Hidden Vegetables: Boost the nutritional value and add extra flavor by finely dicing vegetables like onions (beyond the soup mix), bell peppers, carrots, or even zucchini. Sautéing them lightly before adding them to the mixture can enhance their sweetness and prevent excess moisture.
• Make it Cheesy: For a delightful twist, incorporate 1/2 to 1 cup of shredded cheese (cheddar, mozzarella, or a blend) into the meat mixture before shaping. The cheese will melt into the loaf, adding a gooey, savory element.
• Spice it Up: If you enjoy a little heat, add a pinch of red pepper flakes, a dash of your favorite hot sauce, or a teaspoon of smoked paprika to the meat mixture for an extra kick.
• Experiment with Glazes: While ketchup is classic, don’t hesitate to try other glazes. A brown sugar ketchup glaze (ketchup, brown sugar, a splash of apple cider vinegar), or a savory mushroom gravy poured over the top after baking, can offer exciting new flavor profiles.
• Individual Meatloaf Muffins: For quick cooking and perfect portion control, shape the mixture into smaller, individual meatloaves and bake them in a muffin tin. Reduce baking time significantly (check at 25-30 minutes).

Serving Suggestions for Your Meatloaf

This savory onion soup meatloaf is a versatile main course that pairs beautifully with a variety of classic side dishes, creating a truly comforting and satisfying meal. Here are some of my favorite ways to serve it, along with ideas for creative leftovers:

• Classic Potato Sides: Nothing complements meatloaf quite like potatoes. Serve alongside fluffy Instant Pot mashed potatoes, perfect for soaking up any delicious juices, or crispy oven-roasted potatoes seasoned with herbs. You could also opt for a rich and creamy potato gratin or simple baked potatoes.
• Hearty Vegetable Pairings: Round out your meal with some wholesome vegetables. Steamed green beans with a knob of butter, buttery corn on the cob, glazed carrots, or even roasted asparagus or broccoli florets are fantastic choices. For an extra touch, sautéed mushrooms or caramelized onions make a wonderful addition.
• Bread for Sopping: Don’t forget something to soak up all those savory flavors! Soft breadsticks, warm and sweet honey-butter dinner rolls, or a crusty baguette are perfect for this.
• Fresh Green Salad: A light and refreshing simple tossed salad with a vinaigrette dressing provides a lovely contrast to the richness of the meatloaf. It adds crunch and freshness to the plate.
• The Ultimate Meatloaf Sandwich: Leftover meatloaf slices are a dream for sandwiches! Pile them high on toasted bread, perhaps with a slice of melty mozzarella or provolone cheese, and a dollop of extra ketchup or a spread of mayo. It makes for a hearty sandwich, reminiscent of a delicious meatball sub.
• Creative Leftover Ideas: Beyond sandwiches, transform leftover meatloaf into a savory hash with diced potatoes and onions, crumble it into a rich meatloaf chili, or even incorporate it into a pasta sauce for a quick and flavorful weeknight dinner.
• Don’t Forget Dessert: Finish off your comforting meal with a classic sweet treat like these fudgy lunch lady brownies, perhaps topped with a scoop of vanilla ice cream.

Storing and Reheating Leftovers Like a Pro

One of the best things about meatloaf is that it often tastes even better the next day! Proper storage and reheating ensure your leftovers remain delicious and safe to enjoy. Here’s how to manage your meatloaf leftovers:

• Refrigerate Properly: Once cooled to room temperature (within two hours of cooking), transfer any leftover meatloaf to an airtight container. This helps maintain its moisture and prevents odors from seeping in or out. Store it in the refrigerator for up to 4 days.
• How to Reheat for Best Results:
  • Oven Method (Recommended): For the best texture, wrap individual slices or the whole leftover loaf loosely in aluminum foil. Place it on a baking sheet and reheat in a preheated oven at 250-300ºF (120-150°C) until it’s warmed through. The foil helps to trap moisture, preventing it from drying out. You can also add a tablespoon or two of beef broth or water to the foil packet for extra moisture.
  • Microwave Method (Quick Option): If you’re short on time, individual slices can be reheated in the microwave. Place a slice on a microwave-safe plate and cover it with a damp paper towel or a microwave-safe lid. Heat in 30-60 second intervals until hot. Be careful not to overheat, as this can dry out the meatloaf.
• Freezing for Long-Term Storage: Meatloaf freezes exceptionally well, making it a fantastic meal prep option.
  • Slices for Convenience: My favorite method is to cut the cooled meatloaf into individual slices. Wrap each slice tightly in plastic wrap, then place the wrapped slices in a freezer-safe bag or container. This makes it incredibly easy to grab just one or two portions to thaw and reheat as needed.
  • Whole Loaf: You can also freeze a whole cooled meatloaf by wrapping it tightly in several layers of plastic wrap, then a layer of aluminum foil.
  • Thawing and Reheating: Frozen meatloaf slices can be thawed overnight in the refrigerator or reheated directly from frozen in the oven (which will take longer, around 30-45 minutes at 300°F). For best results, allow it to thaw before reheating. Frozen meatloaf will last for up to 3 months.
