Ingredients You’ll Need

This recipe comes together with pantry staples and just a few fresh ingredients. Here’s what you’ll need:

For the Meatloaf:

• 1 ½ lbs ground beef (80/20 or leaner)

• 1 packet dry French onion soup mix

• ½ cup plain breadcrumbs

• ¼ cup milk

• 2 eggs

• 1 tablespoon Worcestershire sauce

• ½ teaspoon garlic powder

• ½ teaspoon black pepper

• ¼ cup chopped fresh parsley (optional)

For the Topping:

• 1 cup caramelized onions (or sautéed until soft and golden)

• 1 cup shredded or sliced Swiss cheese

• Optional: extra parsley or crispy fried onions for garnish

If you don’t already have caramelized onions on hand, they’re worth the time. Just slice up some sweet onions and cook them low and slow in butter until golden brown and rich in flavor.

Step-by-Step Instructions

You don’t need any fancy equipment—just a slow cooker and a little prep time. Here’s how it comes together:

Step 1: Mix the Meatloaf

In a large bowl, combine the ground beef, French onion soup mix, breadcrumbs, milk, eggs, Worcestershire sauce, garlic powder, pepper, and parsley (if using). Mix until everything is just combined. Don’t overdo it—overmixing can lead to a tough meatloaf. A gentle hand here goes a long way.

Step 2: Shape and Place in Crockpot

Form the mixture into a loaf shape and place it in your crockpot. For easier cleanup later, you can line the base with parchment paper or give it a light spray with nonstick cooking spray.

Step 3: Add the Caramelized Onions

Spoon the caramelized onions right over the top of the meatloaf. They’ll infuse the meat with that deep, sweet onion flavor while it cooks.

Step 4: Slow Cook

Cover and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours, depending on your schedule. You’re looking for an internal temperature of 160°F. If you don’t already have a meat thermometer, this is a great recipe to invest in one.

Step 5: Add the Cheese

About 10 to 15 minutes before you’re ready to serve, add your shredded or sliced Swiss cheese on top. Cover again and let the cheese melt into a glorious, gooey layer. It’s okay to peek—you’ll want to make sure it’s fully melted and starting to get a little bubbly.

Step 6: Slice and Serve

Let the meatloaf rest for about 10 minutes before slicing. This helps it hold together and keeps all those flavorful juices inside. Serve it up with mashed potatoes, green beans, or thick slices of crusty bread to soak up every bit of savory goodness.

Pro Tips for the Best French Onion Meatloaf

• Use good-quality Swiss cheese or try Gruyère if you want to get fancy. The nuttiness pairs beautifully with the sweet onions.

• Make your caramelized onions ahead of time and keep them in the fridge for up to a week. They’re a great addition to burgers, sandwiches, or grilled cheese, too.

• Don’t skip the resting time. It might be tempting to slice right in, but your patience will be rewarded.

• Avoid overmixing the meat mixture. It’s the most common reason for a dry or dense meatloaf.

• Line your slow cooker. It makes cleanup faster and prevents sticking.

Variations to Try

Once you’ve tried the original version, don’t be afraid to mix things up:

• Swap the cheese. If Swiss isn’t your thing, provolone, mozzarella, or Gruyère all work beautifully.

• Add mushrooms. Sautéed mushrooms add depth and bring even more French onion soup vibes to the dish.

• Make it saucy. A splash of beef broth or a ladle of onion gravy can make this meatloaf extra moist and flavorful.

• Try mini loaves. Shape the mixture into smaller loaves for individual portions—they cook a little faster, too.

Make-Ahead Tips for Busy Days

This recipe already works beautifully for busy schedules thanks to the crockpot, but you can make it even easier with a little planning ahead.

Prep in Advance:

You can mix the meatloaf ingredients and shape the loaf up to a day in advance. Just wrap it tightly and store it in the fridge until you’re ready to cook. The flavors actually develop a bit more this way, which is a nice bonus.

Freeze for Later:

Want to double up and save one for later? Go ahead and prepare two loaves—one for now, one to freeze. Wrap the uncooked loaf in plastic wrap and then foil, and freeze for up to 3 months. When you’re ready to cook, thaw it overnight in the fridge, then follow the regular slow-cooking instructions.

Best Side Dishes to Serve With It

This meatloaf is rich and flavorful, so simple sides that balance the richness work really well. Here are a few tried-and-true pairings:

• Mashed potatoes – Creamy and classic. Garlic mashed or buttery Yukon golds are especially good.

• Green beans – A light, crisp vegetable balances out the richness. Try them steamed or sautéed with garlic.

• Roasted carrots – Their sweetness plays nicely with the savory meatloaf and onions.

• Crusty bread – Use it to soak up the juices. It’s the kind of detail that makes dinner feel extra special.

• Simple salad – Something crisp and acidic like a vinaigrette-dressed arugula salad helps cut through the richness.

Storage and Leftovers

Leftovers might be the best part of this recipe. Here’s how to keep them fresh:

Refrigerator:

Store slices in an airtight container for up to 4 days. Reheat gently in the microwave or oven, covered with foil to preserve moisture.

Freezer:

Wrap slices individually and freeze for up to 3 months. They’re great for a quick lunch—just thaw and heat.

Make it a Sandwich:

Warm a slice and place it between two pieces of crusty bread with a little extra cheese. Maybe even add a few crispy onions on top. You’ll thank yourself.

Frequently Asked Questions

Can I use ground turkey instead of beef?

Yes, but keep in mind that turkey is leaner and may result in a slightly drier loaf. Consider adding an extra tablespoon of milk or a splash of broth to keep it moist.

Do I have to caramelize the onions?

While caramelized onions bring that deep, sweet-savory flavor, you can sauté them until golden if you’re short on time. It’s still delicious, just a little less intense.

What if I don’t have a crockpot?

No worries—you can bake this meatloaf in a 375°F oven for about 45–55 minutes. Just keep an eye on the internal temperature, and add the cheese during the last 10 minutes.

Can I use pre-shredded cheese?

Yes, but freshly shredded Swiss melts more smoothly. If using pre-shredded, try to avoid the kinds with added starches—they can affect the texture.
