Ingredients for French Onion Beefloaf

Gathering these simple ingredients is the first step to creating a truly memorable meal. This ground beef French onion meatloaf relies on a few key players to achieve its incredible flavor:

900 grams ground beef – I prefer a 85/15 lean-to-fat ratio for the best flavor and moisture.
120 grams breadcrumbs – These help bind the meatloaf and give it a tender texture. Panko works great!
50 grams grated Parmesan cheese – It adds a wonderful salty, umami depth that complements the beef.
60 milliliters whole milk – A little liquid helps keep the meatloaf moist and tender.
2 large eggs – These are essential for binding all the ingredients together.
15 milliliters Worcestershire sauce – This secret ingredient adds a complex savory note.
5 grams fine sea salt – To enhance all the other flavors.
2 grams freshly ground black pepper – For a touch of spice.
2 large yellow onions, sliced – The star of the show! Slicing them thinly helps them caramelize beautifully.
28 grams unsalted butter – Used to get those onions perfectly golden and sweet.
240 milliliters beef broth – This creates the savory sauce that bathes the meatloaf.
8 slices Swiss cheese – For that classic French onion soup-inspired cheesy topping.

How to Make French Onion Beefloaf

Get ready for the easiest, most flavorful meatloaf you’ve ever made! This step-by-step guide will walk you through creating a truly special meal.

Step 1: In a large mixing bowl, gently combine the 900 grams ground beef, 120 grams breadcrumbs, 50 grams grated Parmesan cheese, 60 milliliters whole milk, 2 large eggs, 15 milliliters Worcestershire sauce, 5 grams fine sea salt, and 2 grams freshly ground black pepper. I find using my hands is the best way to mix everything together until it’s just combined; overmixing can make the meatloaf tough.
Step 2: Shape the beef mixture into a compact oval loaf. Place it directly in the center of your slow cooker insert. This helps ensure even cooking.
Step 3: Now for those delicious onions! In a skillet over medium heat, melt the 28 grams unsalted butter. Add the 2 large yellow onions, sliced. Cook them, stirring occasionally, for about 20 minutes. You’re looking for them to become deeply golden brown and wonderfully soft – that’s where the rich French onion flavor really starts.
Step 4: Pour the 240 milliliters beef broth into the skillet with the caramelized onions. Stir everything together and let it simmer for 2 minutes, scraping up any browned bits from the bottom of the pan.
Step 5: Spoon this glorious onion and broth mixture evenly over the beefloaf sitting in the slow cooker. It smells amazing already!
Step 6: Cover the slow cooker and set it to cook on LOW for 6 to 8 hours. This slow cooking process is key to how to make French onion meatloaf so tender. You’ll know it’s done when the internal temperature reaches 165°F (71°C) and the juices run clear. This French onion meatloaf slow cooker method ensures maximum flavor with minimal effort.
Step 7: About 10 minutes before you’re ready to serve, carefully arrange the 8 slices Swiss cheese over the top of the beefloaf. Pop the lid back on and let the residual heat melt the cheese into gooey perfection. The aroma of melted cheese and savory beef is simply irresistible.
Step 8: Slice your beautiful French Onion Beefloaf and serve warm. Enjoy this incredible homemade French onion meatloaf!
