Ingredients

Scale

3-4 large Sweet Onions, sliced
4 tbsp Salted Butter
1 tbsp Olive Oil
1 tsp Sea Salt
1 tsp Coarse Black Pepper
1 tsp Granulated Sugar
1 lb Ground Beef (80/20)
1 cup Italian Breadcrumbs
1 cup Milk
1 Large Egg
1 oz French Onion Soup Mix (non-alcoholic)
1/2 cup Vegetable Broth
1/2 tsp Worcestershire Sauce (alcohol-free)
4 oz Swiss Gruyère or Provolone cheese, sliced

Instructions

In a skillet over medium heat, melt butter and olive oil. Add sliced onions, sugar, salt, and pepper. Sauté until onions are deeply caramelized, about 15 minutes.
Spread the caramelized onions evenly across the bottom of the slow cooker.
In a large bowl, combine ground beef, breadcrumbs, milk, egg, onion soup mix, and Worcestershire sauce until well mixed.
Shape the meat mixture into a loaf and place it directly on top of the onions in the crockpot.
Pour the vegetable broth around the sides of the meatloaf.
Cover and cook on low for 6-8 hours or high for 3-4 hours.
In the last 30 minutes of cooking, drape the cheese slices over the top of the meatloaf to melt.
Carefully lift the meatloaf out and serve with the onion drippings from the bottom.

Notes

Ensure the French onion soup mix and Worcestershire sauce are certified alcohol-free. If the meatloaf is too soft to lift, let it rest for 10 minutes in the crockpot before removing. Store leftovers in an airtight container for up to 3 days.
