Who knew meatloaf could be so easy and delicious? I love throwing everything in the crockpot and letting it do the work. Plus, that melted cheese makes it feel extra special! 🧀

Key Ingredients & Substitutions

Ground Beef: I recommend using an 80/20 blend for juicy meatloaf. If you’re looking for a healthier option, consider using ground turkey or chicken, though they may need more seasoning since they are leaner.

French Onion Soup Mix: This adds a lot of flavor quickly. If you prefer, you can make your own by mixing onion powder, garlic powder, beef bouillon, and some dried herbs.

Swiss Cheese: While I love Swiss for its meltiness, you can swap it for provolone or even cheddar for a different flavor profile. Mozzarella is another great option for a milder taste.

Onions: Yellow onions are my go-to for caramelizing due to their sweetness. You can also use sweet onions like Vidalia or even red onions for a slightly different taste.

Balsamic Vinegar: This is optional, but it adds a nice depth to your caramelized onions. If you don’t have it, a splash of red wine or apple cider vinegar can work too!

How Do I Get the Best Caramelized Onions?

Caramelized onions bring a sweet depth to this meatloaf. Here’s how to do it perfectly:

  • Heat butter and olive oil in your skillet over medium heat.
  • Add sliced onions and stir them to coat. Cook slowly, stirring every few minutes for about 20-25 minutes.
  • Keep an eye out; if they begin to brown too quickly, reduce the heat.
  • For extra flavor, add balsamic vinegar in the last 5 minutes, then take them off the heat when they’re golden and soft.

This method ensures those onions turn sweet and tender, ideal for topping the meatloaf! Enjoy the process, and don’t rush it! Slow cooking is key to unlocking their natural sugars.

Ingredients You Will Need:

For the Meatloaf:

  • 2 lbs ground beef (80/20 blend for juiciness)
  • 1 large onion, finely chopped (for meatloaf mix)
  • 1 packet (1 oz) French onion soup mix
  • 1 cup dry breadcrumbs
  • 2 eggs, lightly beaten
  • 1/2 cup milk
  • 2 cloves garlic, minced
  • 1 tsp Worcestershire sauce
  • Salt and freshly ground black pepper, to taste
  • 8 oz Swiss cheese slices

For the Topping:

  • 3 large onions, thinly sliced (for caramelized onion topping)
  • 2 tbsp butter
  • 1 tbsp olive oil
  • 1 tbsp balsamic vinegar (optional, for depth in onions)
  • Fresh parsley, chopped (for garnish)

How Much Time Will You Need?

This hearty Crockpot French Onion Meatloaf will take about 15 minutes of prep time, followed by a cooking time of 6 to 7 hours on low (or 3 to 4 hours on high). Perfect to set in the morning and enjoy a delicious meal by dinner!

Step-by-Step Instructions:

1. Prepare the Caramelized Onions:

In a large skillet, heat butter and olive oil over medium heat. Add the sliced onions and let them cook slowly, stirring occasionally, for about 20-25 minutes. You want them to turn golden brown and sweetly caramelized. If you’re feeling adventurous, mix in balsamic vinegar during the last 5 minutes for an extra kick of flavor. Once done, remove them from the heat and set aside.

2. Make the Meatloaf Mixture:

In a big bowl, combine the ground beef, finely chopped onion, French onion soup mix, dry breadcrumbs, beaten eggs, milk, minced garlic, Worcestershire sauce, salt, and pepper. Get your hands in there or use a spoon to mix everything together until it’s well combined. This will be the base of your meatloaf!

3. Shape and Layer the Meatloaf:

Take half of your meat mixture and shape it into a loaf that fits inside your crockpot. Place it in the bottom of the pot. Now, layer the Swiss cheese slices evenly on top of the meat. Next, take the remaining meat mixture and gently press it over the cheese to seal it within the loaf.

4. Cook in the Crockpot:

Spread half of the caramelized onions on top of the meatloaf. Put the lid on the crockpot and cook on low for 6 to 7 hours or high for 3 to 4 hours. You’ll know it’s ready when the internal temperature reaches 160°F (71°C).

5. Finishing Touches:

About 15-20 minutes before you’re ready to eat, take the rest of the caramelized onions and spread them on top of the meatloaf. This will warm them up and add even more flavor!

6. Serve:

Once your meatloaf is cooked through, carefully lift it out of the crockpot and place it on a serving platter. Don’t forget to garnish with some freshly chopped parsley for a nice touch. Slice it up and enjoy this cozy, cheesy goodness warm!

This comforting meatloaf is perfect for family dinners and served with your favorite sides. Enjoy your delicious creation!

Can I Use Ground Turkey Instead of Beef?

Yes, you can! Just keep in mind that ground turkey is leaner than beef, so you might want to add an extra egg or a bit more milk to keep the meatloaf moist.

How Do I Store Leftovers?

Store any leftover meatloaf in an airtight container in the refrigerator for up to 3 days. You can reheat it in the microwave or a skillet over low heat. It’s delicious even the next day!

Can I Make This Meatloaf Without Bread Crumbs?

Absolutely! You can substitute breadcrumbs with crushed saltine crackers, oatmeal, or even ground almonds for a gluten-free option. Adjust the quantity as needed to achieve the right texture.

What if I Don’t Have a Crockpot?

No worries! You can bake the meatloaf in a preheated oven at 350°F (175°C) for about 60-75 minutes. Just cover it with foil for the first half of the baking time to keep it moist.
