👨🍳 Instructions
- 1
In a large bowl, combine ground beef, dry onion soup mix, breadcrumbs, eggs, milk, Worcestershire sauce, garlic powder, pepper, and shredded Swiss. Mix just until everything is combined — don’t overwork the meat.
- 2
Form the mixture into a loaf shape and place it into your slow cooker (spray the insert first for easier cleanup).
- 3
Cover and cook on low for 6–7 hours or on high for 3–4 hours, until the internal temperature reaches 160°F.

About 10–15 minutes before serving, lay the Swiss cheese slices over the top of the meatloaf, cover again, and let them melt.

Once the cheese is melted and gooey, turn off the slow cooker. Let the meatloaf rest for 5–10 minutes, then slice and serve.
💡 Pro Tips
- ✓Mix meatloaf ingredients only until just combined - overmixing develops gluten proteins and creates a dense, rubbery texture instead of tender results.technique
- ✓Use a meat thermometer to confirm 160°F internal temperature because slow cookers vary widely in heating patterns and visual doneness is unreliable.equipment160°F
- ✓Add Swiss cheese slices only in the final 10-15 minutes to prevent overcooking - extended heat breaks down cheese proteins causing separation and oil pooling.timing10-15 minutes
- ✓Rest the meatloaf 5-10 minutes after cooking so juices redistribute through the meat fibers, preventing a dry slice when cut immediately.timing5-10 minutes
- ✓Form meatloaf to fit your slow cooker with 1-2 inches clearance on sides for even heat circulation and proper cooking throughout.technique1-2 inches clearance
