Step-by-Step Instructions

Follow these steps to create your flavor-packed French Onion Meatloaf. The crockpot does most of the work, so you don’t have to!

Step 1. Sauté the Onions

Start by caramelizing your onions, as this is what gives the dish its signature French onion flavor.

• Heat a skillet over medium heat and add the butter and olive oil.
• Toss in the sliced onions, sprinkle them with a pinch of salt and pepper, and cook until golden and caramelized (about 15–20 minutes). Stir occasionally.
• Once done, set them aside.

Step 2. Mix the Meatloaf

Next, assemble your meat mix.

• In a large mixing bowl, combine the following ingredients: ground beef, egg, breadcrumbs, onion soup mix, garlic powder, Worcestershire sauce, and optional shredded mozzarella.
• Use your hands (or a spoon if you prefer) to mix everything together until combined evenly. Form the mixture into a loaf shape.

Step 3. Assemble in the Crockpot

Time to get everything in the crockpot!

• Add the caramelized onions to the bottom of the crockpot, followed by the beef broth.
• Carefully place your meatloaf on top of the onions.

Step 4. Cook

Set your crockpot and relax as the slow cooker works its magic.

• Cover and cook on LOW for 6 hours or HIGH for 3–4 hours.
• Use a meat thermometer to ensure the internal temperature reaches 160°F (71°C).

Step 5. Top with Cheese

Once the meatloaf is fully cooked, take it to the next level with melted Swiss cheese.

• Lay Swiss cheese slices over the top of the meatloaf, cover, and allow the cheese to melt for about 5–10 minutes.

Step 6. Serve and Enjoy!

Carefully remove the meatloaf from the crockpot and slice it into hearty portions. Spoon the caramelized onion mixture on top of each serving and garnish with fresh parsley.
