How to Make French Onion Meatballs

Step 1: Prepare the Base

Start by soaking the breadcrumbs in milk for 5 minutes. This ensures they’re moist enough to bind the meatballs perfectly without making them dry.

Step 2: Mix the Meatballs

Add the soaked breadcrumbs, ground beef, herbs, spices, onion, garlic, Gruyere, and egg in a bowl. Mix gently to combine all ingredients without overmixing.

Step 3: Chill and Form

Roll the mixture into meatballs and let them chill for 15 minutes to hold their shape while cooking.

Step 4: Sear the Meatballs

Brown the meatballs in a hot skillet to lock in the flavors and give them a beautiful crust.

Step 5: Make the Sauce

Caramelize onions in the same skillet, add garlic, herbs, and sherry, and let it simmer into a rich sauce.

Step 6: Assemble and Broil

Return the meatballs to the pan, top with cheeses, and broil until melted and golden. Voilà!

Pro Tips for Making French Onion Meatballs

  • Optimal Cheese Melt: For the best gooey cheese, ensure it’s freshly grated, not pre-shredded.
  • Onion Caramelization: Patience is key; let those onions cook slowly for a deep, sweet flavor.
  • Even Searing: Roll meatballs of similar size to ensure even browning and cooking.
  • Sauce Depth: Deglaze the pan thoroughly to incorporate all those browned bits into your sauce.

Make Ahead and Storage

Storing Leftovers

Place any leftover French Onion Meatballs in an airtight container, and they’ll stay fresh in the fridge for up to 3 days.

Freezing

You can freeze the cooked meatballs and sauce separately for up to 3 months. Just ensure they are properly cooled and sealed.

Reheating

Reheat your dish gently on the stove over medium-low heat, adding a splash of stock or water if necessary to loosen the sauce.

FAQs

  1. Can I make these meatballs ahead of time?

    Absolutely! You can prepare them a day in advance. Just keep them chilled and then cook as directed.

  2. What can I use instead of Gruyere cheese?

    If Gruyere is hard to find, Swiss cheese makes for a delightful substitute with its similar melted consistency.

  3. Are there any wine alternatives I can use in the sauce?

    Yes, if you’re avoiding alcohol, try using a bit of apple cider vinegar or additional stock for a punchy depth.

  4. Can I use dried herbs in place of fresh?

    Dried herbs can work in a pinch, but use half the amount called for fresh as they are more potent.

Final Thoughts

These French Onion Meatballs are not just a meal; they’re an experience waiting to happen in your kitchen. Try them and add a little bit of French bistro flair to your next dinner rotation. Bon appétit!

Units Scale

Meatball Ingredients

  • 1 1/2 cups fresh breadcrumbs or panko breadcrumbs
  • 1/4 cup plus 2 tablespoons whole milk
  • 1 1/2 pounds organic ground beef (80/20 or 85/15 ratio)
  • 1 tablespoon chopped parsley
  • 1 teaspoon fresh thyme leaves
  • 1 teaspoon herbes de Provence
  • 1 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 large white onion, finely minced
  • 4 cloves garlic, pressed
  • 3/4 cup grated Gruyere cheese, divided
  • 1 large egg, whisked
  • 1 cup shredded whole milk mozzarella cheese

French Onion Sauce Ingredients

  • 4 tablespoons olive oil, divided
  • 2 tablespoons ghee or butter
  • 2 1/2 large white onions, sliced
  • Salt to taste
  • Black pepper to taste
  • 4 cloves garlic, pressed
  • 1 teaspoon herbes de Provence
  • 1 teaspoon dried thyme
  • 1/4 cup sherry or white wine
  • 1 1/2 tablespoons flour
  • 2 1/4 cups beef stock
  • 2 teaspoons fresh thyme leaves

Instructions

  1. Prepare the Meat Mixture: In a bowl, soak the breadcrumbs in milk for 5 minutes until soft. Meanwhile, place ground beef in a large mixing bowl.
  2. Mix the Meatballs: Add soaked breadcrumbs, parsley, thyme, herbes de Provence, salt, pepper, minced onion, garlic, ¼ cup of Gruyere, and the whisked egg to the beef. Gently combine with clean hands until just mixed, being careful not to overwork the meat.
  3. Form the Meatballs: Scoop out 2-tablespoon portions using a cookie scoop or spoon, then roll each into a round ball with wet hands. Place on a tray and chill in the fridge for 15 minutes.
  4. Sear the Meatballs: Heat a large cast-iron skillet over medium-high heat and add 2 tablespoons of olive oil. Adding batches, sear meatballs for 8-10 minutes until browned on all sides, then transfer to a tray. Repeat until all are browned.
  5. Caramelize the Onions: In the same skillet, add remaining 2 tablespoons of oil or butter and 2 tablespoons of ghee. Add sliced onions with a pinch of salt and cook for 20-25 minutes, stirring frequently, until deeply caramelized and jammy.
  6. Add Aromatics and Deglaze: Stir in garlic, herbes de Provence, and thyme, cooking for 30 seconds until fragrant. Pour in sherry and cook until reduced by half, about 30 seconds.
  7. Make the Sauce: Sprinkle flour into the onions and stir for 30 seconds. Gradually add beef stock, whisking to incorporate and create a smooth sauce. Simmer for 5 minutes to thicken.
  8. Broil the Cheesy Topping: Turn on the broiler to high. Off heat, stir in fresh thyme leaves. Nestle seared meatballs back into the skillet, top with remaining Gruyere and mozzarella cheeses. Broil for 5-7 minutes until cheese is melted and bubbly.
  9. Serve: Garnish with extra thyme, then spoon meatballs with sauce and melted cheese into bowls. Serve with toasted bread or over mashed potatoes for a hearty, cheesy meal.

Notes

  • For extra flavor, add caramelized onions on top before broiling for a richer taste.
  • Use freshly grated Gruyere for optimal melting and flavor.
  • Can be prepared in advance and reheated; freeze leftovers for convenience.
  • Ensure the sauce is thick enough by simmering a few extra minutes if needed.
  • Serve with crusty bread or over mashed potatoes for a complete meal.
