Soft, flavorful meatballs nestled in a bed of cozy onion goodness just like you’d find in a bowl of French Onion Soup. To make them even better, we’ve added a generous layer of Swiss and Mozzarella cheese on top, then baked them to perfection. It’s like turning your favorite soup into a hearty meal.

Introducing the Baked French Onion Meatballs – an incredibly lip smackingly, delicious culinary creation that pays homage to the classic French Onion Soup in a whole new way.
These succulent meatballs are combined with deep, rich caramelized onions, aromatic thyme, savory beef broth and topped with a gooey cheese topping. They have all the oniony flavor that French Onion soup is known for and with the addition of protein, they become a satisfying meal in their own right.
How to Make The Most Delicious French Onion Meatballs:
Step One – Bake Not Fry
- Now, before we start, let’s talk about meatballs. In many traditional recipes, you’d find instructions to fry them. Frying is great; it gives you that lovely crust and texture. But, it can also be a bit of a chore. It demands extra time, more attention, and, let’s not forget, a good amount of oil and a huge mess to clean up.
- We’re about to make things easier, and honestly, I think, more delicious too. Instead of frying, we’re going to bake our meatballs. That’s right – straight into the oven they go. You might wonder why we’d take this route. Well, here’s the beauty of it:

Step Two – Multi Tasking
- While those meatballs are baking to a perfect, juicy brown, we’re simultaneously cooking down a heap of onions. We’re talking about thinly sliced onions that slowly caramelize in a skillet, infused with salt, pepper, and thyme.
- The onions will take as much time to reduce down as the meatballs take to cook, maybe even a little bit more.

Step 3 – Thicken the Sauce
- By this stage the meatballs should be out of the oven and cooling on the baking sheet. Now it’s time to make the sauce.
- When the onions are at their peak of deliciousness, we introduce a touch of dry sherry and a sprinkle of flour. This creates a luscious base for our sauce. As the beef stock joins the party, the sauce thickens beautifully.

Step 4 – Putting it all together
- Finally! What we’ve all been waiting for. It’s time to nestle those succulent meatballs into the onions and top it with some Swiss and Mozzarella cheese. You can certainly use all Swiss or all mozzarella or any other kind of cheese – Gruyere goes fantastic too. Pop them back into the oven.
- What emerges is pure magic. The cheese becomes golden and bubbly, the sauce is hot and oh-so-satisfying, and those meatballs? They’re tender and infused with all the flavors of the caramelized onions and savory sauce. It’s like a French Onion Soup party in your mouth.

I can’t begin to tell you how good these meatballs are, but the finishing touch for me is in the bread. Grab a big ‘ole chunk of fresh bread – I like to toast it kind of like how the soup gets topped- and serve the meatballs on top.
OOOOhhhh man! This is truly EPIC! Enjoy friends!
