My Best Tips

Be gentle when mixing your meat nobody likes tough meatloaf. Using lean meat gives you great flavor without swimming in grease. I always cook a tiny piece in a pan to check the seasoning before I put the whole thing in the slow cooker. Try to shape it evenly so it cooks the same all the way through.

Slow Cooker Success

Those onions on the bottom aren't just for flavor they keep your meatloaf from sticking. The low and slow cooking makes everything taste amazing. Just resist peeking under the lid while it cooks you want to keep all that heat and moisture inside.

Storing Your Leftovers

If you have any leftovers they'll keep in the fridge for three days. Want to save it longer? Pop it in the freezer it's good for up to three months. Just let it thaw overnight in the fridge then warm it up in the oven or microwave until it's hot through.

What to Serve With It

I love serving this with creamy mashed potatoes they're perfect for soaking up all those amazing juices. Green beans on the side add nice color or try a fresh Caesar salad. If you're feeling fancy pour a glass of Pinot Noir it goes beautifully with the rich flavors.

Frequently Asked Questions

→ Can I use different cheese varieties?
Yes, while Swiss cheese is traditional, you can use Gruyère or provolone as mentioned in the recipe. Any good melting cheese will work well.
→ Why do we add sugar to the onions?
Sugar helps the onions caramelize more quickly and evenly. It enhances their natural sweetness and helps them develop that rich brown color.
→ Can I make this without a slow cooker?
Yes, you can caramelize the onions in a skillet and bake the meatloaf in the oven at 350°F for about 1 hour or until internal temperature reaches 160°F.
→ Can I prep this ahead of time?
You can mix and shape the meatloaf mixture a day ahead and store it in the refrigerator. You can also caramelize the onions in advance if using the skillet method.
→ What can I substitute for cooking sherry?
You can use beef broth, red wine, or white wine as alternatives to cooking sherry. Each will provide a slightly different but still delicious flavor profile.
