Ingredients

Scale

🔹 For the Beefloaf:

900 grams ground beef (preferably 80/20 lean-to-fat ratio)

120 grams plain breadcrumbs

50 grams grated Parmesan cheese

60 milliliters whole milk

2 large eggs

15 milliliters Worcestershire sauce

5 grams fine sea salt

2 grams freshly ground black pepper

🔹 For the French Onion Topping:

2 large yellow onions, thinly sliced

28 grams unsalted butter (2 tablespoons)

240 milliliters beef broth

8 slices Swiss cheese

Instructions

1. Prepare the Beefloaf Mixture

  • In a large mixing bowl, add:

    • 900g ground beef

    • 120g breadcrumbs

    • 50g grated Parmesan

    • 60ml milk

    • 2 eggs

    • 15ml Worcestershire sauce

    • 5g salt

    • 2g black pepper

  • Mix gently until all ingredients are combined. Avoid overmixing to keep the loaf tender.

2. Shape and Place in Crockpot

  • Form the beef mixture into a compact oval-shaped loaf.

  • Gently place the loaf into the base of your crockpot. You can use parchment paper underneath for easier removal.

3. Caramelize the Onions

  • In a medium skillet, melt 28g unsalted butter over medium-low heat.

  • Add the 2 sliced yellow onions.

  • Stir occasionally and cook for 20 minutes, until onions become deeply golden and soft.

  • Pour in 240ml beef broth and stir for 2 minutes, scraping any brown bits off the pan.

4. Add Onion Topping

  • Spoon the entire onion and broth mixture evenly over the meatloaf in the crockpot.

5. Slow Cook

  • Cover and cook on LOW for 6 to 8 hours, or until internal temperature reaches 160°F (71°C).

  • Avoid lifting the lid during cooking to maintain even temperature.

6. Add Cheese

  • About 10 minutes before serving, lay 8 slices of Swiss cheese over the hot meatloaf.

  • Cover again and allow the cheese to melt fully.

7. Serve

  • Carefully slice and serve hot, making sure each piece is topped with onions and melted cheese.

Notes

  • For a lighter version, substitute ground beef with lean turkey or chicken.

  • Gluten-free? Use certified gluten-free breadcrumbs or rolled oats.

  • To avoid soggy texture, elevate the loaf using a rack or line with parchment.

  • Let the loaf rest for 10 minutes before slicing for the cleanest cuts.

  • Leftovers are fantastic in sandwiches!
