Step‑by‑Step Instructions for Cheesy French Onion Meatballs
Step 1: Prepare the Meatball Mixture
In a large bowl, combine the ground beef, breadcrumbs, egg, minced garlic, thyme, salt, and pepper. Mix gently until just combined, being careful not to overwork the meat. Using your hands, form the mixture into 1-1.5 inch meatballs. Set them aside on a plate as you prepare to brown them in a skillet.
Step 2: Brown the Meatballs
In a large skillet, heat a tablespoon of olive oil over medium heat. Once hot, carefully add the meatballs in a single layer, ensuring they’re not overcrowded. Brown them for about 4-5 minutes on each side until golden brown and cooked through, reaching an internal temperature of 160°F. Remove the meatballs from the skillet and set them aside.
Step 3: Caramelize the Onions
In the same skillet, add the sliced onions and a pinch of salt. Sauté over medium-low heat, stirring occasionally for 20-30 minutes, until the onions are golden brown and caramelized. For a quicker caramelization, sprinkle a touch of sugar during cooking to enhance sweetness. You’ll know they’re done when they’re deep golden and fragrant.
Step 4: Add the Broth
Once the onions are perfectly caramelized, pour in the beef broth, scraping the bottom of the skillet to release any browned bits. Return the meatballs to the skillet, ensuring they are submerged in the broth. Simmer gently for about 5-10 minutes until the meatballs are heated through, absorbing the rich flavors from the caramelized onions.
Step 5: Melt the Cheese
Sprinkle the Gruyère cheese generously over the meatballs and onion mixture in the skillet. Cover the skillet with a lid and cook on low heat for 2-3 minutes, allowing the cheese to melt beautifully into a creamy layer. Keep an eye on it; you want it gooey and bubbly but not burnt!
Step 6: Serve and Enjoy
Once the cheese is ideally melted, remove the skillet from heat. Serve the Cheesy French Onion Meatballs hot, alongside crusty bread, creamy mashed potatoes, or your favorite pasta. Delve into the delightful combination of flavors that this comforting dish offers, perfect for any cozy family gathering!

Expert Tips for Cheesy French Onion Meatballs

Cheesy French Onion Meatballs Recipe FAQs
What kind of onions should I use for Cheesy French Onion Meatballs?
For the best flavor, I recommend using yellow onions. They caramelize beautifully, developing a sweet, rich taste that is essential for this recipe. If you want a milder flavor, you could also use sweet onions, but avoid red onions as they don’t provide the same depth in caramelization.
How should I store leftovers of Cheesy French Onion Meatballs?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Just make sure they cool down before sealing to avoid moisture buildup. When you’re ready to enjoy them again, gently reheat in a skillet over low heat, adding a splash of beef broth to keep them moist and delicious.
Can I freeze Cheesy French Onion Meatballs?
Absolutely! These meatballs freeze wonderfully. Simply wrap them tightly in plastic wrap, then place them in a freezer-safe container or a heavy-duty freezer bag. They can last up to 3 months in the freezer. When you’re ready to enjoy, thaw overnight in the fridge and reheat on low heat with a little beef broth to maintain the sauce’s richness.
What if my meatballs are too dry?
If your meatballs turn out dry, it could be due to using lean meat or overcooking them. To fix dry meatballs, I suggest adding a little olive oil to the mixture next time. For now, you can serve them with extra beef broth or a creamy sauce to enhance moisture. Just remember to check for an internal temperature of 160°F when cooking!
Can I make Cheesy French Onion Meatballs vegetarian or vegan?
Sure! To make these meatballs suitable for a plant-based diet, substitute the ground beef with a combination of cooked lentils, mushrooms, or even a plant-based meat alternative. You can use a flaxseed meal mixed with water as a binder instead of an egg, and make sure to select vegan cheese or omit it for a completely dairy-free version.
What type of cheese works best in this recipe?
While Gruyère cheese is quintessential for its creamy, nutty flavor, you can certainly experiment with others. Swiss, Fontina, or mozzarella work nicely too. If you’re a cheese lover, feel free to blend different types for a rich and delightful gooey topping!
