Cheesy French Onion Meatballs Ingredients
For the Meatballs
• Ground Beef – the main protein source; for a healthier option, feel free to swap it with ground turkey or chicken.
• Bread Crumbs – these help bind the meatballs together and add a delightful texture; gluten-free breadcrumbs work just as well.
• Egg – acts as a binder; if you’re vegan, ground flaxseed mixed with water can serve as a suitable substitute.
For the Caramelized Onions
• Onions – essential for sweetness and rich flavor; yellow or sweet onions yield the best results when caramelized.
• Olive Oil – used for cooking the onions; butter can enhance the richness if you prefer.
• Sugar – optional, but adding it makes caramelizing the onions quicker and boosts their sweetness.
For the Sauce
• Beef Broth – enhances the overall flavor; vegetable broth provides a lighter option while keeping it equally delicious.
For the Topping
• Gruyère Cheese – the star of the dish, adds a nutty, creamy richness; feel free to substitute with Swiss or Fontina if desired.
These ingredients culminate in the perfect dish of Cheesy French Onion Meatballs, bringing warmth and comfort to every cozy night in!
Step‑by‑Step Instructions for Cheesy French Onion Meatballs
Step 1: Prep Meatballs
In a large mixing bowl, combine ground beef, bread crumbs, and egg, seasoning with salt and pepper. Use your hands to mix until just combined. Form the mixture into meatballs, about 1 to 1.5 inches in diameter, and set aside on a plate. This step ensures your Cheesy French Onion Meatballs are juicy and flavorful.
Step 2: Caramelize Onions
Heat a large skillet over medium-low heat and add olive oil. Once hot, add the sliced onions, stirring occasionally. Cook the onions slowly for 25 to 30 minutes, allowing them to soften and turn a beautiful golden brown. The key here is patience; caramelized onions will infuse your meatballs with sweetness and depth.
Step 3: Brown Meatballs
In the same skillet with the caramelized onions, gently add the prepared meatballs. Increase the heat to medium and brown the meatballs on all sides, about 5 to 7 minutes, turning occasionally with tongs. This step adds a lovely crust, enhancing the flavor of your Cheesy French Onion Meatballs.
Step 4: Make the Sauce
Once the meatballs are browned, return the caramelized onions to the skillet. Pour in the beef broth, making sure to scrape up any browned bits from the bottom for added flavor. Bring the mixture to a gentle simmer, allowing it to bubble for 5 minutes, which melds the flavors together beautifully into a rich sauce.
Step 5: Add Cheese
Sprinkle the Gruyère cheese generously over the top of the meatballs and onions. Cover the skillet with a lid and cook on low heat for about 5 minutes, or until the cheese is melted and bubbly. This melty topping is what makes the Cheesy French Onion Meatballs irresistible and comforting.
Step 6: Serve
Carefully transfer the Cheesy French Onion Meatballs onto a serving platter, spooning some of the rich onion sauce over them. Pair with crusty bread, pasta, or fluffy mashed potatoes to soak up the delightful sauce. Serve hot to enjoy the gooey goodness right away!
