What is French Onion Soup
Perhaps the most famous (or at least the most widely consumed) example of French peasant cuisine is French onion soup. It was initially popularized before the French revolution, when French peasants had to eat whatever was in the garden, including frogs, snails, and, of course, onions. Onion soup variants - although none as decadent as ours today - have been widely consumed in Europe since the days of the Roman Empire.
Today, French onion soup is one of the gold standards of French cuisine, a flavorful, tasty treat that’s perfect for all occasions. Typically, you base a soup around meat stock and plenty of onions, and serve it with crusty toasted bread or croutons on top.
Ingredients
To make these baked chicken meatballs you will need: olive oil, yellow, white or red onions, egg, balsamic vinegar, ground chicken or turkey, mozzarella or gruyere cheese, bread crumbs, garlic, beef (or chicken) stock, fresh herbs salt and pepper.
How to Make French Onion Chicken Meatballs
- Caramelize the onions.
- Shape the meatballs and bake.
- Make the sauce.
- Finish in the oven.
What Onions to Use for French Onion Soup
Wondering what type of onions to use for this? Don’t worry, we’ve got you covered. Different onion varieties have different flavors. Some are sweet, some bitter, some earthier… there’s really a broad range of onion-y tastes. You’ll want to pick the one that suits your needs best.
White and yellow onions, as advised by the legendary Julia Child, have a brighter flavor with plenty of sweetness. There’s a very mild bitter taste to the yellow onion that balances this out. You can use red onions, but these are more bitter than the yellow and white ones, and have less sweetness.
You can also use shallots, with their deep, bright, fresh flavor.
What Else To Use In French Onion Chicken Meatballs
You can try any meat you like. Ground beef, veal, and pork are all classic options for meatballs. Many restaurants will use a combination of beef and veal, or pork and veal, to achieve the best texture. Although we normally wouldn’t recommend using lean beef to make meatballs, because this is such a high-moisture dish, you can get away with using a leaner beef than usual.
When it comes to cheeses, there’s a whole range of options available to you. Mozzarella, Emmental, Comte, Beaufort, Jarlsberg, or Raclette are great options. Gruyere is by far the most traditional for this recipe, but considering we’re messing about with tradition by making it, why not try something new? Either way, you’ll want a cheese that is already relatively soft so it melts easily.
How To Get the Most Out Of Your Onions
When you’re making onion soup, the star of the show, unsurprisingly, is your onions. The trick to making the most of your onions is to caramelize them properly.
Caramelize your onions until they’re nice and brown, and sweet. You’ll want to cook your onions over low heat for, at a bare minimum, 30 minutes. You can take even longer if you like, and trust us when we say the results speak for themselves. This is a great dish to make on a rainy afternoon when you have the time and attention to pay to your onions, because they’ll reward your patience immensely.
French Onion Meatballs Tips
- Use fresh breadcrumbs if you know how to make them to really make this recipe stand out. You can do this very easily with some bread (or better yet, toast) and a food processor. Process the bread, place the crumbs on a tray and bake at 300 F for 10 minutes to get that golden brown finish we all love so much.
- If your meatball mix seems a little dry, cube up some bread very small. Soak these little bits of bread in milk. Incorporate these into your meatballs to add moisture and texture without dominating the palate. This is how Italians traditionally soften up their meatballs, and it’s a trick that works wonders.
How to Store French Onion Meatballs
Your meatballs will keep in the fridge for up to four days in an airtight container. You can make yourself some very indulgent sandwiches with that mixture and a little extra cheese!
You can also freeze these by spreading the cooked meatballs separately on a baking sheet and placing them in the freezer until they’re barely frozen. Then, remove the meatballs and place them in a freezer bag, and return them to the freezer. They will store for up to three months. You can store your sauce as is, in an airtight container, separately from the meatballs.
French Onion Meatballs in Crockpot
You can make these meatballs in a crock pot.
To make crock pot meatballs, simply assemble your meatball mix (chicken, herbs, caramelized onions, breadcrumbs, egg, salt, pepper, and cheese). Once this is well-mixed, separate into little meatballs. Place your raw meatballs in the bottom of your crockpot, top with sauce (in this case onion soup) and let your slow cooker do the work for you!
You don’t have to cook your meatballs before placing them in the crock pot. The naturally occurring juices from the meatballs will enhance the French onion soup, too.

Description
These baked French onion meatballs are loaded with so many flavors, gooey cheese and aromatic herbs.
Ingredients
- 3 tablespoons olive oil
- 3 large white, yellow or red onions, halved and thinly sliced
- 2 tablespoons balsamic vinegar
- 1 pound ( 500 grams) ground chicken
- 3 garlic cloves, minced
- 1 ¼ cups shredded mozzarella or gruyere cheese, divided
- ¼ cup bread crumbs
- 1 large egg
- 2-3 tablespoons fresh chopped parsley
- 1 teaspoon fresh chopped thyme
- ½ teaspoon salt
- ½ teaspoon ground black pepper
- Cooking oil spray for spraying meatballs before baking
- 1 ¾ cups beef or chicken stock
- 1 tablespoon corn flour
- 3-4 fresh thyme sprigs
Instructions
- Heat olive oil in a large skillet over medium-high heat.
- Add the onions and generously season with salt. Cook for about 30 minutes or until the onions are caramelized and jammy, stirring occasionally. Pour in balsamic vinegar to add some additional flavors and add 2 thyme sprigs, cook for a minute. Transfer to a plate. Allow to cool slightly.
- Preheat the oven to 410° F (210° C).
- Take half of the cooled caramelized onion and chop.
- In a large bowl combine the ground chicken, ½ cup shredded mozzarella (or gruyere cheese), bread crumbs, egg, garlic, parsley, thyme, salt and pepper. Add in the chopped caramelized onions. Mix just until combined. Do not over mix!
- Shape into meatballs (I made 14 meatballs about 2-inches in diameter). It is easy to form the mixture into meatballs if your hands are wet. Place the meatballs into the same skillet ( the one you used to cook onions). Spray the meatballs with cooking oil spray generously and bake for 12 minutes.
- Remove the skillet from the oven. Whisk together the beef broth ( or chicken broth) with corn flour in a small bowl. Pour the mixture into the skillet with the meatballs, add in the remaining caramelized onions and top with the remaining mozzarella ( gruyere ) cheese and thyme sprigs.
- Bake for 15 minutes or until cooked through. The internal temperature will be 165 degrees F ( 74 C).
- Serve immediately with crusty bread.
