Step‑by‑Step Instructions for Crockpot French Onion Meatballs
Step 1: Prep Meatballs
In a large mixing bowl, combine ground beef, gluten-free breadcrumbs, finely chopped onion, Worcestershire sauce, garlic powder, salt, and pepper using a fork or your hands until just mixed. Be careful not to overmix, as this can lead to tough meatballs. Allow the mixture to rest for about 10 minutes to help it firm up before shaping.
Step 2: Form Meatballs
With your hands, gently roll the beef mixture into meatballs, aiming for sizes around 1 to 1.5 inches in diameter. This uniform size ensures even cooking throughout. As you form each meatball, place it on a tray or plate lined with parchment paper for easy transfer to the crockpot.
Step 3: Layer in Crockpot
Once all the meatballs are formed, carefully place them in the bottom of your slow cooker. Arrange them in a single layer, ensuring they do not touch, as this allows for even cooking and prevents them from sticking together. This layout also facilitates maximum flavor absorption from the broth.
Step 4: Add Broth
Pour the beef broth slowly over the arranged meatballs, making sure they are mostly submerged. This will not only cook the meatballs but also create a rich, flavorful sauce. You may want to tilt the crockpot slightly to ensure even distribution of the broth over all the meatballs.
Step 5: Cook
Cover the crockpot and set it to low heat for 6 hours. As the meatballs cook, they will absorb the savory broth while becoming tender and juicy. You’ll know they’re done when they reach an internal temperature of 165°F (74°C) and are infused with the delicious flavor of the caramelized onions.
Step 6: Serve
Once cooked, remove the lid and let the meatballs cool for a few minutes. Serve them warm, spooning some of the broth over the top for extra flavor. These Crockpot French Onion Meatballs are perfect on their own or alongside crusty bread to soak up that delightful sauce.

Crockpot French Onion Meatballs Recipe FAQs
What type of ground beef should I use for the meatballs?
For the best flavor and texture, I recommend using ground beef that is 80/20 (lean to fat ratio). This provides enough fat to keep the meatballs juicy. If you prefer a lighter option, ground turkey or chicken works beautifully as a substitute!
How should I store leftover Crockpot French Onion Meatballs?
Store any leftovers in an airtight container in the refrigerator for up to 4 days. To ensure they stay moist, consider pouring a bit of the cooking broth over the meatballs before sealing. This keeps them flavorful and ready for quick reheating later!
Can I freeze Crockpot French Onion Meatballs?
Absolutely! To freeze, first allow the meatballs to cool completely. Layer them in a freezer-safe container with parchment paper between each layer to prevent sticking. They can be safely frozen for up to 3 months. When ready to enjoy, thaw overnight in the fridge, then gently reheat on low heat or in the microwave until warmed through.
What if my meatballs turn out tough?
If your meatballs are tough, it may be due to overmixing the meat mixture. Always mix just until combined and avoid handling the mixture too much while forming the meatballs. If they are still tough after cooking, you can try making a meatball “rehab” by simmering them in extra broth for 15-20 minutes to soften them up.
Are these meatballs suitable for gluten-free diets?
Yes, these Crockpot French Onion Meatballs are gluten-free! Just use gluten-free breadcrumbs, and ensure that your Worcestershire sauce is gluten-free as well. This recipe is a great comfort food option for those wanting to avoid gluten, without sacrificing flavor.
How can I customize the flavor of my meatballs?
You can elevate the flavor of your meatballs in various ways! Consider adding finely chopped fresh herbs like parsley or thyme to the meat mixture for a herby brightness. You can also spice things up by including some crushed red pepper flakes or doubling down on the Worcestershire sauce for a bolder taste. Remember, the more you experiment, the more fun your cooking adventure becomes!
