Crockpot French Onion Meatloaf

Imagine a dish that combines the rich, savory flavors of French onion soup with the comforting texture of meatloaf. This Crockpot French Onion Meatloaf is the ultimate blend of two classics, slow-cooked to perfection for a juicy, flavor-packed meal.

The secret to its deep, umami flavor is caramelized onions, which take time to develop their signature sweetness. If you’re unfamiliar with how to achieve perfectly golden onions, check out this expert guide for step-by-step instructions.

Another crucial component is the cheese topping. Traditional French onion soup uses Gruyère or Swiss cheese for a nutty, melty finish. Learn more about cheese varieties and their best culinary uses by visiting Cheese.com.

Why Make Meatloaf in a Crockpot?

Using a slow cooker to prepare meatloaf has several advantages:

• Retains Moisture: The crockpot locks in steam, keeping the meat tender.
• Hands-Free Cooking: Once set, it requires no additional attention.
• Enhanced Flavor Infusion: Slow cooking allows onions, garlic, and seasonings to deeply penetrate the meat.
• Energy Efficient: Uses less electricity than a conventional oven.

Ingredients Breakdown

For the Meatloaf:

• 2 lbs ground beef (80/20 blend for best texture)
• 1 large yellow onion, thinly sliced
• ½ cup breadcrumbs (or almond flour for a low-carb version)
• ½ cup shredded Swiss or Gruyère cheese
• 2 eggs
• ½ cup beef broth
• 1 tbsp Worcestershire sauce
• 1 tsp garlic powder
• 1 tsp salt
• ½ tsp black pepper

For the French Onion Topping:

• 1 cup caramelized onions
• ½ cup additional shredded Swiss cheese

Step-by-Step Cooking Instructions

1. Caramelizing the Onions

1. Heat a pan over medium-low heat and add 1 tbsp butter.
2. Add thinly sliced onions and cook slowly for about 25 minutes, stirring occasionally.
3. Once golden brown, deglaze with a splash of beef broth for extra flavor.

2. Preparing the Meatloaf Mixture

1. In a large mixing bowl, combine:
   • Ground beef
   • Breadcrumbs
   • Eggs
   • Garlic powder, salt, and pepper
   • Half of the caramelized onions
   • Shredded cheese
2. Mix gently—overmixing can make the meatloaf dense.

3. Shaping and Assembling the Meatloaf in the Crockpot

1. Shape the meat mixture into a loaf shape that fits your crockpot.
2. Line the bottom of the slow cooker with parchment paper (optional, for easy removal).
3. Place the meatloaf inside and pour Worcestershire sauce and beef broth around it.

4. Cooking the Meatloaf

• Cook on low for 6-7 hours or high for 3-4 hours.
• Ensure the internal temperature reaches 160°F (71°C) before serving.

5. Adding the Cheese Topping

1. With 15-20 minutes left, sprinkle the remaining caramelized onions and Swiss cheese over the meatloaf.
2. Cover and let the cheese melt completely.

6. Serving Suggestions

• Let the meatloaf rest for 5 minutes before slicing.
• Garnish with fresh thyme or parsley.
• Serve with classic sides like:
  • Mashed potatoes
  • Steamed green beans
  • A warm baguette

Pro Tips for the Best Crockpot Meatloaf

Recipe Variations & Dietary Adjustments

Frequently Asked Questions (FAQs)

Can I prepare the meatloaf ahead of time?

Yes! Assemble the meatloaf the night before and store it covered in the fridge. When ready, place it directly into the crockpot and cook.

What’s the best type of onion to use?

Yellow onions work best due to their balance of sweetness and depth of flavor. Sweet onions like Vidalia can also be used for a richer taste.

How do I store leftovers?

• Refrigerate for up to 4 days in an airtight container.
• Freeze for up to 3 months (wrap in foil before freezing).
• Reheat in a 350°F oven until warmed through.

Can I use turkey instead of beef?

Yes! Ground turkey makes for a leaner version, though it may be slightly less juicy. Add extra broth to keep it moist.

Serving Pairings & Beverage Suggestions

Side Dishes

• Roasted Brussels sprouts
