Step‑by‑Step Instructions for Cheesy French Onion Meatballs

Step 1: Prepare Meatballs
In a large mixing bowl, combine the ground beef, breadcrumbs, egg, salt, and pepper. Use your hands to mix everything gently until just combined, being careful not to overwork the meat. Form the mixture into meatballs, about 1 to 1.5 inches in diameter, and place them on a plate or a baking sheet.

Step 2: Brown Meatballs
Heat a large skillet over medium heat and add a drizzle of olive oil. Once hot, carefully add the meatballs, making sure to leave space between them for even browning. Cook for approximately 6–8 minutes, turning occasionally, until they are browned all over. Remove the meatballs from the skillet and set them aside on a plate.

Step 3: Caramelize Onions
In the same skillet, add a little more olive oil if needed, then add the sliced onions along with a sprinkle of sugar. Cook on medium-low heat for about 20–25 minutes, stirring frequently until the onions are soft and golden brown. The caramelization process is key to developing the rich flavor for your Cheesy French Onion Meatballs, so be patient!

Step 4: Make Sauce
Once the onions are caramelized, pour in the beef broth, scraping the bottom of the skillet to capture all the flavorful bits. Increase the heat slightly and bring the mixture to a gentle simmer, allowing the broth to combine with the onions for about 3–5 minutes. This will create a savory base for the sauce.

Step 5: Combine
Return the browned meatballs to the skillet, gently nestling them into the onion and broth mixture. Cover the skillet and let them simmer on low heat for an additional 10–15 minutes, allowing the meatballs to cook through and absorb the flavors of the sauce. This step ensures your Cheesy French Onion Meatballs are tender and juicy.

Step 6: Add Cheese
Sprinkle a generous amount of Gruyère cheese over the meatballs, ensuring each one gets a lovely layer. Cover the skillet again and let it cook on low for about 3–5 minutes, or until the cheese is melted and bubbly. The gooey cheese is the finishing touch that takes these meatballs to comfort food heaven.

Expert Tips for Cheesy French Onion Meatballs

• Patience is Key: Caramelizing onions requires time; cooking them slowly prevents burning and brings out their natural sweetness for your Cheesy French Onion Meatballs.

• Don’t Overcrowd the Skillet: When browning the meatballs, give them space to ensure even cooking and a nice sear; this prevents steaming instead of browning.

• Check the Temperature: Ensure meatballs reach an internal temperature of 160°F to guarantee they’re safely cooked through without being dry.

• Use Quality Broth: The richness of the beef broth enhances the flavor of the sauce; opt for low-sodium broth to control seasoning.

• Experiment with Cheese: While Gruyère is a classic choice, don’t hesitate to mix it up with other cheeses like Swiss or mozzarella for a unique twist!
