Step‑by‑Step Instructions for Cheesy French Onion Meatballs
Step 1: Prepare the Meatballs
In a large mixing bowl, combine your ground beef, breadcrumbs, egg, and seasonings. Mix the ingredients gently until just combined, being careful not to overwork the mixture. Shape the mixture into meatballs about 1 to 1.5 inches in diameter. Set them aside on a plate while you prepare to cook.
Step 2: Cook the Meatballs
Heat a large skillet over medium-high heat and add a splash of olive oil. Once the oil is hot, gently place the meatballs in the skillet, ensuring they are spaced apart. Cook for about 5-7 minutes, turning occasionally, until all sides are browned and they are cooked through, reaching an internal temperature of 160°F. Remove the meatballs and set aside.
Step 3: Caramelize the Onions
In the same skillet, reduce the heat to medium-low and add another drizzle of olive oil along with your sliced onions. Stir frequently and cook for 20-25 minutes, allowing the onions to become golden brown and caramelized. If desired, sprinkle in a bit of sugar after about 10 minutes to enhance sweetness. Keep an eye on them to prevent burning.
Step 4: Create the Sauce
Once the onions are perfectly caramelized, pour in the beef broth, scraping the bottom of the pan to deglaze it. Bring the mixture to a gentle simmer and let it cook for about 5-10 minutes, allowing the sauce to reduce and thicken slightly. Carefully return the meatballs to the skillet, letting them simmer together for another 5 minutes, absorbing the flavors.
Step 5: Add Cheese
Preheat your broiler to high. After the meatballs have simmered, top the mixture generously with shredded Gruyère cheese. Place the skillet under the broiler for about 2-3 minutes, watching closely until the cheese melts and becomes bubbly and golden. Remove from the heat, and let it cool slightly before serving.
Step 6: Serve
Transfer your Cheesy French Onion Meatballs to a serving dish, garnishing with fresh herbs if desired. Serve these delightful meatballs warm alongside crusty bread, mashed potatoes, or pasta for a complete meal. Enjoy the rich flavors and comforting textures that are sure to please everyone at the table!

Make Ahead Options
These Cheesy French Onion Meatballs are perfect for meal prep enthusiasts! You can prepare the meatballs and the caramelized onion sauce up to 3 days in advance. Simply form the meatballs and refrigerate them separately from the caramelized onions and sauce, which can also be stored in an airtight container. To maintain quality, allow them to cool completely before refrigerating to prevent excess moisture. When ready to serve, reheat the sauce over medium heat, reintroduce the meatballs, and simmer until heated through. Top with Gruyère cheese and broil for a few minutes just before serving for that gooey, melty finish—making your weeknight dinner both effortless and delicious!
