Timing

This Crockpot French Onion Meatballs recipe requires approximately 4 hours and 30 minutes total time, which is a significant portion of more efficient than traditional stovetop methods. Here’s the breakdown:

• Prep time: 30 minutes
• Initial cooking (onions): 2 hours on HIGH
• Meatball cooking: 2 hours on LOW
• Total active time: Just 45 minutes of hands-on work

Step-by-Step Instructions

Step 1: Caramelize the Onions

Heat butter and olive oil in a large skillet over medium-low heat. Add sliced onions with a pinch of salt and cook for 15-20 minutes, stirring occasionally, until golden brown and caramelized. Transfer to your crockpot and add brown sugar, then cook on HIGH for 2 hours with the lid slightly ajar to allow moisture to evaporate.

Step 2: Prepare the Meatball Mixture

While onions caramelize, combine ground beef, panko breadcrumbs, beaten egg, minced garlic, salt, pepper, and parsley in a large bowl. Mix gently with your hands until just combined – overmixing creates tough meatballs.

Step 3: Form Perfect Meatballs

Using a cookie scoop or your hands, form the mixture into 20-24 uniform meatballs, approximately 1½ inches in diameter. This size ensures even cooking and optimal flavor distribution.

Step 4: Create the French Onion Base

Add beef broth, chicken stock, Worcestershire sauce, thyme, and bay leaves to the caramelized onions in the crockpot. Stir to combine and season with salt and pepper.

Step 5: Cook the Meatballs

Gently nestle the formed meatballs into the onion mixture, ensuring they’re mostly submerged. Cover and cook on LOW for 2 hours, or until meatballs reach an internal temperature of 165°F.

Step 6: Add the Cheese Finale

During the last 15 minutes of cooking, sprinkle Gruyère and Parmesan cheeses over the meatballs. Cover and allow the cheese to melt completely, creating that signature French onion soup experience.
