Can You Really Make Meatloaf in a Crockpot?

Absolutely. A crockpot is actually one of the best ways to cook meatloaf if you want it extra moist. Unlike the oven, which can sometimes dry out the edges, slow cooking locks in moisture and gently cooks the meat all the way through.

To avoid a soggy texture, it’s important to shape the loaf properly and allow some space around it in the slow cooker. This helps excess juices circulate instead of pooling directly around the meat.

Ingredients for the Crockpot French Onion Meatloaf

Using the right ingredients makes all the difference in flavor and texture. Each component plays a specific role in building that rich French onion taste.

Ground Beef

The base of the meatloaf. Choose 80/20 for the best balance of flavor and moisture.

Yellow Onions

Essential for that signature French onion flavor. They become sweet and caramelized as they cook.

Onion Soup Mix

Boosts the savory depth and adds seasoning in one simple step.

Breadcrumbs

Help bind the mixture together and keep the loaf tender.

Eggs

Act as a binder to hold everything in place.

Beef Broth

Enhances the richness and keeps the meat mixture moist.

Worcestershire Sauce

Adds a subtle tang and umami depth.

Garlic

Gives a warm, savory backbone to the dish.

Provolone or Swiss Cheese

Melted on top for that classic French onion soup finish.

Fresh Thyme

Adds a light herbal touch that complements the onions beautifully.

How To Make the Crockpot French Onion Meatloaf

This process is simple and perfect for anyone looking for an easy dinner recipe that feels special.

After combining the ingredients, you’ll shape the loaf and let the slow cooker do the work. The final cheesy topping takes it over the top.

Step 1: Caramelize the Onions

Slice the onions and cook them in a skillet over medium heat until soft and golden brown. This step builds the deep, sweet flavor that defines the dish.

Step 2: Mix the Meatloaf

In a large bowl, combine ground beef, onion soup mix, breadcrumbs, eggs, beef broth, Worcestershire sauce, garlic, and half of the caramelized onions. Mix gently until just combined.

Step 3: Shape and Prepare

Form the mixture into a loaf shape. Place it in the crockpot on a sheet of parchment paper or foil sling for easier removal.

Step 4: Slow Cook

Cover and cook on low for 6–7 hours or high for 3–4 hours, until the internal temperature reaches 160°F.

Step 5: Add the Cheese Topping

In the final 15 minutes, top the meatloaf with the remaining caramelized onions and slices of provolone or Swiss cheese. Cover again and allow the cheese to melt completely.
