In a large bowl, combine the ground beef, French onion soup, breadcrumbs, eggs, garlic powder, black pepper, and thyme. Mix gently until just combined—do not overmix, as this can make the meatloaf dense.
Step 2: Shape the Meatloaf
Form the mixture into a loaf shape. You can either place it directly in the crockpot or set it on a small foil sling to make removal easier later.
Step 3: Cook Low and Slow
Cover and cook:
-
LOW for 6–7 hours, or
-
HIGH for 3–4 hours
The meatloaf is done when the internal temperature reaches 160°F (71°C).
Step 4: Add the Swiss Cheese
About 20–30 minutes before serving, layer the Swiss cheese over the top of the meatloaf. Cover and continue cooking until the cheese is fully melted and bubbly.
Step 5: Garnish and Serve
Sprinkle with fresh parsley if desired. Carefully remove the meatloaf, slice, and serve hot.
