How to Make Crockpot French Onion Meatloaf – Step-by-Step Instructions

1. Caramelize the Onions

Caramelized onions bring a rich sweetness to the dish. Here’s how to get them just right:

• Peel and slice 2 large sweet onions into thin strips.
• Heat 2 tablespoons of butter and 1 tablespoon of olive oil in a large skillet over medium heat.
• Add the onions with a pinch of sea salt and 1 teaspoon of granulated sugar.
• Stir occasionally, letting the onions cook slowly for 20-25 minutes until golden brown and soft.
• Pour in 2 tablespoons of cooking sherry. Stir to deglaze the pan, scraping up any flavorful bits.
• Remove from heat and set aside.

Tip: Low and slow is key. Rushing this step can burn the onions.

2. Mix the Meatloaf

This meat mixture holds everything together while staying moist and flavorful:

• In a large bowl, combine:
  • 1 ½ pounds ground beef (80/20 is best)
  • ¾ cup Italian herb breadcrumbs
  • ½ cup milk
  • 1 large egg
  • 1 packet (about 1 ounce) French onion soup mix
  • 1 tablespoon Worcestershire sauce
  • ½ teaspoon black pepper
• Gently mix everything with your hands until just combined. Overmixing can make the meatloaf tough.

3. Shape and Assemble in the Crockpot

• Shape the meat mixture into a loaf shape that will fit in your slow cooker.
• Line the bottom of the crockpot with foil or parchment paper if you want easy cleanup (optional).
• Place the meatloaf inside.
• Spoon the caramelized onions over the top, spreading them evenly.

4. Slow Cook to Perfection

• Cover and cook on LOW for 6 hours or HIGH for 3 hours.
• Check for doneness with a meat thermometer. It should read 160°F in the center.

5. Add the Cheese Topping

• Once the meatloaf is fully cooked, sprinkle 1 ½ cups of shredded Swiss, Gruyère, or provolone cheese over the top.
• Cover the crockpot and let the cheese melt for about 5-10 minutes. It should be gooey and slightly bubbly.

Serving Suggestions

This French Onion Meatloaf is rich and hearty, so it pairs best with simple, comforting sides. Here are a few favorites that balance the flavors:

• Creamy Mashed Potatoes: Smooth and buttery, perfect for soaking up the juices from the meatloaf.
• Steamed Green Beans or Carrots: A light, fresh side to cut through the richness.
• Roasted Baby Potatoes: Crisp outside, fluffy inside—they add a satisfying crunch.
• Buttered Egg Noodles: Simple and comforting, letting the meatloaf shine.
• Garden Salad: A crisp salad with vinaigrette adds a refreshing contrast.

Serve the meatloaf sliced, with extra caramelized onions spooned over the top, and finish with a sprinkle of fresh thyme for a pop of color.

Storage and Meal Prep Tips

This recipe is make-ahead friendly and keeps well for leftovers:

• Make Ahead:
  • Mix the meatloaf ingredients and caramelize the onions up to 1 day in advance. Store them separately in airtight containers in the refrigerator.
  • When ready to cook, assemble the meatloaf in the crockpot and cook as directed.
• Refrigerate Leftovers:
  • Store cooked meatloaf in an airtight container in the fridge for up to 3 days.
  • Reheat in the microwave or oven until warmed through.
• Freeze for Later:
  • Slice the cooked meatloaf into portions. Wrap each slice tightly in plastic wrap and place in a freezer-safe bag.
  • Freeze for up to 3 months.
  • Thaw overnight in the fridge before reheating.

Variations for This Recipe

• Ground Turkey: Swap beef for ground turkey for a lighter option.
• Extra Cheese: Mix shredded cheese into the meatloaf for a cheesier version.
• Mushrooms: Add sautéed mushrooms to the caramelized onions for an earthy twist.
• Garlic Lovers: Stir in 2 cloves of minced garlic when cooking the onions.

Tips and Tricks for Success

• Caramelize Slowly: Take your time with the onions. Low heat and patience bring out their natural sweetness. Rushing this step can lead to burnt or bitter onions.
• Mix Gently: Overmixing the meat can result in a dense, tough loaf. Combine the ingredients until just blended.
• Use a Meat Thermometer: Check that the internal temperature of the meatloaf reaches 160°F for safe and juicy results.
• Foil Lining for Easy Cleanup: Lining your crockpot with foil makes removing the meatloaf easier and speeds up cleaning.
• Choose Your Cheese: Swiss is mild and nutty, Gruyère is rich and melts beautifully, and provolone offers a slightly sharper flavor. Pick what suits your taste.
