Ingredients

→ Beefloaf Base

01 900 grams ground beef
02 120 grams breadcrumbs
03 50 grams grated Parmesan cheese
04 60 milliliters whole milk
05 2 large eggs
06 15 milliliters Worcestershire sauce
07 5 grams fine sea salt
08 2 grams freshly ground black pepper

→ Topping

09 2 large yellow onions
10 28 grams unsalted butter
11 240 milliliters beef broth
12 8 slices Swiss cheese

Directions

Step 01

In a large mixing bowl, thoroughly blend ground beef, breadcrumbs, Parmesan cheese, milk, eggs, Worcestershire sauce, salt, and pepper until uniform.

Step 02

Form the beef mixture into a compact loaf and arrange gently in the base of the crockpot.

Step 03

In a medium skillet over medium heat, melt butter. Add sliced onions and cook, stirring occasionally, for 20 minutes or until deeply golden and softened.

Step 04

Stir in beef broth to the caramelized onions, allowing it to absorb and enrich the mixture for 2 minutes.

Step 05

Evenly spoon the caramelized onion and broth mixture over the prepared beefloaf inside the crockpot. Cover and cook on low heat for 6 to 8 hours, or until the loaf is cooked through and juices run clear.

Step 06

About 10 minutes before serving, layer Swiss cheese slices on top of the hot beefloaf, cover, and allow to melt completely.

Step 07

Slice and serve warm, ensuring each portion is topped with melted cheese and caramelized onions.

Notes

  1. Allow the beef mixture to rest at room temperature for 10 minutes before shaping to enhance texture.
  2. For best results, use freshly grated Swiss cheese for optimal melting and flavor.
