How to Make Crockpot French Onion Meatloaf with Melted Swiss Cheese
- Prepare the Onions
Slice 3–4 large sweet onions and layer them in the bottom of a 6-quart slow cooker. Dot with butter, drizzle olive oil, and sprinkle with salt, pepper, and sugar. - Slow Cook the Onions
Set the crockpot to LOW and cook for 9 hours. (Shortcut: caramelize onions in a skillet over medium heat for 15–20 minutes if you’re short on time.) - Make the Meatloaf Mixture
In a large bowl, gently combine ground beef, Italian herb breadcrumbs, milk, egg, and the French onion soup mix. Form into a loaf shape. - Add Liquids and Layer
Pour cooking sherry and Worcestershire sauce over the cooked onions in the slow cooker. Place the meatloaf on top of the onion bed. - Cook the Meatloaf
Set to HIGH and cook for 3 hours, or until the internal temperature reaches 160°F. Avoid lifting the lid during cooking to keep heat steady. - Melt the Cheese
Once cooked, layer cheese slices over the top. Cover and cook for 20–30 more minutes until gooey and melted. - Slice and Serve
Let the meatloaf rest slightly, then slice and serve topped with those luscious onions and the flavorful broth from the bottom. - Garnish
Sprinkle with fresh thyme for a touch of brightness and elegance.
