Instructions
- Prep and Bake the Meatballs:
- Preheat the oven to four hundred degrees and line a baking sheet with parchment paper. In a large mixing bowl, combine ground chicken, Parmesan, almond meal or bread crumbs, parsley, onion, egg, garlic, salt, and pepper. Work gently with your hands until just combined. Use a one and a half inch scoop or your hands to form even meatballs and space them out on the prepared baking sheet. Bake for fifteen to twenty minutes until the meatballs are golden and reach an internal temperature of one hundred sixty five degrees for safe eating.
- Caramelize the Onions:
- While the meatballs bake, heat olive oil and butter together in a large heavy skillet over medium heat. Add all of the thinly sliced yellow onions and stir to coat. Cook them slowly, stirring every few minutes, letting the onions turn deep golden and totally soft. This should take about twenty five minutes and is key for sweet flavor and silky texture. Scrape the bottom often and lower the heat if the onions darken too quickly.
- Build the French Onion Sauce:
- When the onions are golden, add the minced garlic to the pan. Cook for about one minute until it smells fragrant, careful not to let it brown. Pour in beef broth then add fresh thyme, onion powder, salt, and black pepper. Bring the mixture to a boil briefly, then lower the heat and let it simmer for five more minutes so the flavors meld and the sauce thickens a bit.
- Finish and Serve:
- Nestle the baked chicken meatballs gently into the skillet with the onion sauce. Spoon some sauce over the tops so they soak up the flavors. Sprinkle both Gruyère and Havarti cheeses generously on top. Cover the pan with a lid or foil so the cheese melts into gooey goodness, about three to five minutes. Serve hot, straight from the skillet, finished with extra thyme and a crack of pepper if desired.

My favorite moments are watching my kids sneak extra cheese on top or dipping a chunk of crusty bread right in the sauce I love how Gruyère melts into little pools that soak into every oniony nook making this dish irresistible for cheese lovers
Storage Tips
Let the meatballs cool fully before storing and refrigerate in an airtight container for up to four days For longer storage freeze them with or without sauce for up to two months To reheat thaw in the fridge and warm gently in the oven or microwave adding a splash of broth if needed to keep the sauce loose
Ingredient Substitutions
Ground turkey works just as well as chicken if that is what you have Use any mix of melty cheeses if Gruyère or Havarti are not available Swiss or mozzarella will still give a lovely gooey finish For gluten free choose almond meal or certified gluten free bread crumbs
