How to Make Crockpot French Onion Meatballs

Step 1: Caramelize the Onions

Start by melting butter in a skillet over medium heat, then slowly cook the sliced yellow onions until they turn golden brown and sweetly fragrant, about 20-30 minutes. This step builds the rich base for your meatballs and sauce.

Step 2: Mix the Meatball Ingredients

In a large bowl, combine ground beef, bread crumbs, egg, minced garlic, and half of the French onion soup mix. Stir gently until everything is evenly incorporated without overmixing, which helps keep meatballs tender.

Step 3: Shape the Meatballs

Use your hands or a scoop to form bite-sized meatballs, about 1 inch in diameter. Place them on a baking sheet or plate ready for cooking.

Step 4: Brown the Meatballs (Optional but Recommended)

Sear the meatballs in a hot skillet for a couple of minutes on all sides until beautifully browned. This adds extra flavor, but if you’re short on time, you can skip this step and cook them directly in the crockpot.

Step 5: Combine and Cook in Crockpot

Transfer the meatballs to the crockpot, add the caramelized onions, remaining French onion soup mix, and beef broth. Stir gently to combine, cover, and cook on low for 4 to 6 hours until meatballs are cooked through and flavors meld beautifully.

Pro Tips for Making Crockpot French Onion Meatballs

• Use Fresh Onions: Fresh yellow onions caramelize best and provide sweetness that canned won’t match.
• Don’t Skip the Browning: Browning meatballs before slow cooking locks in flavor and helps texture.
• Stir Gently: When combining ingredients or after adding to the crockpot, avoid excessive stirring to keep meatballs intact.
• Low and Slow Cooking: The longer cooking time on low heat lets flavors deepen and the sauce thicken naturally.
• Modify the Broth: Adjust broth amount to get your preferred sauce consistency—less for thicker sauce, more if you want it soupy.

How to Serve Crockpot French Onion Meatballs

Garnishes

Fresh parsley or thyme adds a pop of green and a fragrant finish, while a sprinkle of grated Swiss or Gruyère cheese amps up that French onion vibe perfectly.

Side Dishes

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Place cooled meatballs and sauce in an airtight container and refrigerate for up to 4 days. They stay moist and flavorful, ready for a quick reheat.

Freezing

You can freeze cooked meatballs with sauce in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating gently on the stove or microwave.

Reheating

Warm leftovers slowly in a saucepan over low heat, stirring occasionally until heated through. This helps preserve the tenderness of the meatballs and keeps the sauce luscious.
