French Onion Meatballs Recipe

Introduction

French Onion Meatballs bring together the rich flavors of French onion soup with tender, juicy meatballs nestled in a silky caramelized onion gravy. Topped with melted cheese, this comforting dish is perfect for family dinners or special occasions without extra fuss.

Ingredients

• 1 1/2 lbs (680g) ground beef (or mix of beef & pork)
• 1 cup breadcrumbs
• 1/2 cup whole milk
• 1 large egg
• 1 small onion, finely minced
• 2 cloves garlic, minced
• 1 teaspoon Worcestershire sauce
• 1 teaspoon dried parsley
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 3 large yellow onions, thinly sliced
• 3 tablespoons butter
• 2 tablespoons olive oil
• 2 teaspoons sugar (optional, aids caramelization)
• 1 teaspoon salt
• 2 cloves garlic, minced
• 2 tablespoons all-purpose flour
• 1 cup beef broth
• 1/2 cup white grape juice or apple juice (alcohol-free)
• 1 teaspoon fresh thyme (or 1/2 teaspoon dried)
• Salt & pepper, to taste
• 1 1/2 cups shredded Gruyère or mozzarella
• Fresh parsley, for garnish

Instructions

1. Step 1: In a large bowl, combine the breadcrumbs and milk; let them soak for 5 minutes to hydrate.
2. Step 2: Add ground beef, egg, minced onion, garlic, Worcestershire sauce, parsley, salt, and black pepper to the soaked breadcrumbs. Gently mix until combined and shape into golf ball-sized meatballs.
3. Step 3: Heat a little olive oil in a skillet over medium-high heat. Brown the meatballs in batches until they are golden on all sides but not fully cooked through. Transfer them to a plate.
4. Step 4: In the same skillet, melt butter with olive oil. Add sliced onions, sugar, and salt. Cook over medium-low heat, stirring occasionally, for 25–30 minutes until onions are deeply golden and caramelized. Stir in minced garlic and cook for 1 more minute.
5. Step 5: Sprinkle flour over the caramelized onions and cook for 2 minutes, stirring constantly. Slowly whisk in beef broth and grape or apple juice until the mixture is smooth. Add thyme and season with salt and pepper to taste. Simmer until the gravy thickens slightly.
6. Step 6: Transfer the browned meatballs to a baking dish. Pour the caramelized onion gravy evenly over the meatballs. Sprinkle shredded cheese on top.
7. Step 7: Bake in a preheated oven at 375°F (190°C) for 20–25 minutes, until the meatballs are cooked through and the cheese is melted and bubbling.
8. Step 8: Let the dish rest for 5 minutes before garnishing with fresh parsley. Serve hot.

Tips & Variations

• For juicy meatballs, avoid overmixing and use milk-soaked breadcrumbs for moisture.
• If short on time, brown and cook meatballs fully in the skillet, add the onion gravy, then cover to melt the cheese without baking.
• Try mixing beef and pork for extra flavor or substitute with turkey or chicken for a lighter version.
• Swap Gruyère for mozzarella, provolone, or Swiss cheese depending on your preference.
• Serve over mashed potatoes, buttered egg noodles, or with crusty bread and a side of roasted green beans or salad.

Storage

Assemble the dish up to 24 hours in advance and bake just before serving. Store leftovers in an airtight container in the refrigerator for up to 4 days. Freeze meatballs with the gravy (without cheese) for up to 3 months. Reheat gently in the oven or on the stove until warmed through and cheese is melted.

FAQs

Can I use a different type of meat?

Absolutely. A blend of beef and pork adds flavor, but you can also use ground turkey or chicken for a lighter option.

How do I know when the meatballs are fully cooked?

Bake them until the internal temperature reaches 160°F (71°C) and the cheese on top is melted and bubbling, usually about 20–25 minutes.

Instructions

1. Hydrate Breadcrumbs: In a large bowl, combine breadcrumbs and milk; let rest for 5 minutes to allow the breadcrumbs to soak and soften.
2. Mix & Shape: Add ground beef, egg, minced onion, garlic, Worcestershire sauce, parsley, salt, and pepper to the soaked breadcrumbs. Gently mix until combined without overworking the meat. Form into golf ball–sized meatballs.
3. Brown Meatballs: Heat a little olive oil in a skillet over medium-high heat. Sear meatballs in batches, browning them on all sides but not cooking through. Transfer browned meatballs to a plate.
4. Caramelize Onions: In the same skillet, melt butter with olive oil. Add sliced onions, sugar, and salt. Cook over medium-low heat, stirring occasionally for 25–30 minutes until onions are deeply golden and caramelized. Stir in minced garlic and cook for 1 more minute.
5. Make Gravy: Sprinkle flour over the caramelized onions and cook while stirring for 2 minutes to eliminate raw flour taste. Slowly whisk in beef broth and grape or apple juice until smooth. Add thyme and season with salt and pepper to taste. Simmer until gravy thickens slightly.
6. Assemble: Place meatballs into a baking dish. Pour the onion gravy evenly over the meatballs. Sprinkle shredded Gruyère or mozzarella cheese on top.
7. Bake: Bake in a preheated oven at 375°F (190°C) for 20–25 minutes, or until meatballs are cooked through and cheese is bubbly and golden.
8. Serve: Let rest for 5 minutes after baking. Garnish with fresh parsley and serve hot as a comforting main dish.

Notes

• Tips for juicy meatballs: Don’t overmix the meat; use milk-soaked breadcrumbs; let meatballs rest after browning to retain juices.
• Faster skillet version: Cook meatballs through in the pan, add the onion gravy, then cover the skillet to melt the cheese—skip baking.
• Serving ideas: Spoon over mashed potatoes, buttered egg noodles, or crusty bread; pair with roasted green beans or a crisp salad for a full meal.
• Variations: Use a beef–pork blend for richer flavor; swap in ground turkey or chicken for a lighter version; try different cheeses such as provolone or Swiss for topping.
• Make-ahead & storage: Assemble the dish up to 24 hours in advance and refrigerate until ready to bake. Refrigerate leftovers for up to 4 days; freeze meatballs with gravy (without cheese) for up to 3 months.
• Common mistakes: Avoid rushing the caramelization of onions; do not skip the flour cooking step to prevent raw taste; avoid overbaking meatballs to keep them tender.
