Step-by-Step Instructions to Make Crockpot French Onion Meatballs Easily

1. Form the meatballs: In a large bowl, combine all meatball ingredients. Mix gently with your hands until just combined (overmixing can make tough meatballs). Shape into 1.5-inch balls, making approximately 24-28 meatballs.

2. Brown the meatballs: Heat a tablespoon of oil in a large skillet over medium-high heat. Working in batches, brown the meatballs on all sides (about 2 minutes per side). They don’t need to be fully cooked. Transfer to a plate lined with paper towels.

3. Caramelize the onions: In the same skillet, add butter and olive oil. Add the sliced onions with a pinch of salt. Cook on medium-low heat, stirring occasionally for 15-20 minutes until deeply golden. Add brown sugar and cook for another 5 minutes.

4. Make the sauce: Sprinkle flour over the onions and stir for 1 minute. Gradually add beef broth while stirring to prevent lumps. Add Worcestershire sauce, thyme, and bay leaves. Bring to a simmer.

5. Combine in crockpot: Transfer the caramelized onions and sauce to the slow cooker. Gently add the browned Crockpot French Onion Meatballs. Ensure the French Onion Soup Meatballs are mostly covered by the sauce.

6. Slow cook: Cover and cook on low for 4-6 hours or on high for 2-3 hours until meatballs are cooked through and tender.

7. Finish with cheese: 10 minutes before serving, sprinkle Gruyère cheese over the top. Cover until melted.

FAQs About Cooking Crockpot French Onion Meatballs

Can I make these meatballs without browning them first?
While you can skip browning, this step adds significant flavor and helps the meatballs hold their shape. If short on time, you can place them directly in the slow cooker, but expect a softer texture.

Can I use frozen meatballs instead of homemade?
Yes! Use 2 pounds of quality frozen meatballs and skip to the onion-caramelizing step. Add 30 minutes to the cooking time if starting from frozen.

Is it possible to make this recipe dairy-free?
Absolutely. Omit the Parmesan in the meatballs and replace the Gruyère with your favorite dairy-free melting cheese alternative, or simply leave it out.

Can I prepare this the night before?
Yes! Form the meatballs and caramelize the onions, then refrigerate separately overnight. Combine everything in your slow cooker the next morning.

How do I know when the meatballs are fully cooked?
They should reach an internal temperature of 165°F (74°C). After the recommended cooking time, cut one open to ensure it’s no longer pink inside.
