French Onion Beef Meatballs-Easy Flavorful Recipe this Recipe

Ingredients:

  • 1 ½ cups breadcrum extractbs (or panko)
  • ¼ cup + 2 tbsp whole milk
  • 1 ½ lbs ground beef (85/15 lean)
  • 1 tbsp chopped fresh parsley
  • 1 tsp fresh thyme leaves (plus extra for garnish)
  • 1 tsp herbes de Provence
  • 1 tsp salt
  • ¼ tsp black pepper
  • ½ large white onion, minced
  • 4 cloves garlic, minced
  • ¾ cup grated Gruyere cheese (divided)
  • 1 egg, whisked
  • 1 cup shredded mozzarella cheese
  • 4 tbsp olive oil (divided)
  • 2 tbsp butter

Preparing the Meatball Mixture

First, let’s get ourum extractreadcrumbs and milk ready. In a medium bowl, combine the 1 rum extractups of breadcrumbs with ¼ cup of whole milk. Give it a gentle stir and let it sit for about 5 minutesrum extracthis allows the breadcrumbs to soften and absorb the milk, which is crucial for creating tender, cohesive meatballs that won’t fall apart during cooking. While that’s happening, in a large bowl, add the 1 ½ pounds of ground beef. To this, we’ll add our flavor enhancers. Sprinkle in the 1 tablespoon of chopped fresh parsley, 1 teaspoon of fresh thyme leaves, 1 teaspoon of herbes de Provence, 1 teaspoon of salt, and ¼ teaspoon of black pepper. Don’t forget the aromatics! Add the ½ large white onion, which should be finely minced, and the 4 cloves of minced garlic. These will infuse the meatballs with a wonderful savory depthrum extractow, take your softened breadcrumb mixture and add it to the ground beef. Finally, pour in the whisked 1 egg. The egg acts as a binder, holding all these delicious ingredients together.

Forming and Browning the Meatballs

Now comes the fun part: forming the meatballs. Gently, and I mean gently, mix all the ingredients in the large bowl together with your hands until they are just combined. Overmixing can lead to tough meatballs, so be mindful of that. Once everything is incorporated, roll the mixture into uniform balls, about 1 ½ inches in diameter. You should get around 20-24 meatballs from this amount of meat. To cook them, heat 2 tablespoons of the olive oil in a large skillet over medium-high heat. It’s important to get the oil nice and hot before adding the meatballs to ensure a good sear. Carefully place the meatballs into the hot skillet, making sure not to overcrowd the pan. You might need to work in batches. Brown them on all sides, which typically takes about 5-7 minutes per batch. This browning step is essential for developing a flavorful crust and adding to the overall deliciousness of our French Onion Meatballs. Once browned, remove the meatballs from the skillet and set them aside on a plate.

Sautéing the Onions for the Sauce

After browning the meatballs, we’ll start building the flavorful French onion sauce. In the same skillet (don’t worry about cleaning it – those browned bits are pure flavor!), add the 2 tablespoons of butter and the remaining 2 tablespoons of olive oil over medium heat. Once the butter has melted and is slightly foaming, add the remaining ½ large white onion, which you’ll want to slice thinly this time. Cook the onions, stirring occasionally, until they are softened and nicely caramelized. This process takes patience; we’re aiming for a deep golden-brown color and a sweet, rich flavor. This usually takes about 15-20 minutes. If the onions start to stick too much, you can add a tablespoon of water to the pan to loosen them up. We want them to be tender and sweet, reminiscent of a classic French onion soup.

Developing the Sauce and Baking the Meatballs

Once the onions are beautifully caramelized, it’s time to bring everything together. Stir in the 1 teaspoon of fresh thyme leaves (the extra ones we reserved), and cook for about 30 seconds until fragrant. Now, pour in the remaining ¼ cup of whole milk. Scrape the bottom of the pan with a wooden spoon to loosen any browned bits stuck there – this is where so much of the flavor is! Let the milk simmer gently for a minute or two, allowing it to reduce slightly and create a base for our sauce. Return the browned meatballs to the skillet, nestling them into the onion and milk mixture. Sprinkle ¾ cup of the grated Gruyere cheese evenly over the meatballs and onions. Next, evenly distribute the 1 cup of shredded mozzarella cheese over the top.

Finishing and Serving the French Onion Meatballs

Pop the skillet into a preheated oven at 375°F (190°C). Bake for about 10-15 minutes, or until the cheese is melted, bubbly, and has a lovely golden-brown hue. The meatballs will finish cooking through in the oven, and the cheese will create a glorious, melty topping that binds everything together with that classic French onion appeal. Once they come out of the oven, let them rest for a few minutes before serving. This allows the juices to redistribute, making the meatballs even more tender. Garnish with a few extra fresh thyme leaves for a pop of color and aroma. These French Onion Meatballs are fantastic served on their own, or you can spoon them over crusty bread or noodles for a complete meal. The rich, savory meatballs, combined with the sweet caramelized onions and gooey, melted cheese, create a truly comforting and decadent dish.

Frequently Asked Questions about French Onion Meatballs:

Can I make these French Onion Meatballs ahead of time?

Absolutely! You can prepare the meatballs and refrigerate them for up to 24 hours before cooking. The onion broth can also be made a day in advance. When you’re ready to serve, simply brown the meatballs, add them to the simmering broth, and continue with the recipe as directed, adding the cheese for the final broiling step. This makes them a fantastic option for entertaining!

What kind of bread is best for dipping with French Onion Meatballs?

A good quality, crusty bread is ideal. Sourdough, a French baguette, or a rustic country loaf work wonderfully. The key is a bread that can stand up to the rich broth without falling apart. Toasting it lightly beforehand can also add a delightful crunch and enhance its flavor.
