Step‑by‑Step Instructions for Cheesy French Onion Meatballs
Step 1: Prep the Meatballs
In a large mixing bowl, combine ground beef with your favorite seasonings, such as salt and pepper. Form the mixture into bite-sized meatballs, about 1.5 inches in diameter. Heat a skillet over medium-high heat, add olive oil, and sear the meatballs for 6-8 minutes until they are browned on all sides. Remove the meatballs from the skillet and set them aside.
Step 2: Caramelize the Onions
Using the same skillet, reduce the heat to medium-low and add a bit more olive oil if needed. Add thinly sliced onions and sprinkle a touch of sugar to aid caramelization. Sauté the onions for about 20 minutes, stirring occasionally, until they become deeply golden and soft. The aroma will fill your kitchen, setting the tone for those delicious Cheesy French Onion Meatballs.
Step 3: Create the Sauce
Once the onions are perfectly caramelized, pour in beef broth and optional red wine. Stir well to combine all the flavors, scraping up any browned bits from the bottom of the skillet. Bring the mixture to a simmer over medium heat, allowing it to cook for about 5 minutes until slightly thickened. This rich sauce will be the perfect base for your meatballs.
Step 4: Combine Meatballs and Sauce
Gently return the browned meatballs to the skillet, nestling them into the sauce. Spoon some of the sauce over the meatballs to infuse them with flavor. Let everything simmer together for an additional 5-10 minutes on low heat, ensuring the meatballs are cooked through and soaked with that savory sauce.
Step 5: Melt the Cheese
Sprinkle a generous layer of grated Gruyère cheese over the meatballs and sauce, and cover the skillet with a lid. Cook for 3-5 minutes on low heat, or until the cheese is bubbly and melted, creating a gooey topping. The final step brings together all the flavors in these Cheesy French Onion Meatballs, making them irresistibly delicious.
Make Ahead Options
These Cheesy French Onion Meatballs are a fantastic choice for meal prep, allowing you to enjoy a delicious dinner with ease! You can prepare the meatballs and caramelized onions up to 24 hours in advance. Simply form the meatballs and sauté the onions, then store them separately in airtight containers in the refrigerator. When you’re ready to enjoy, combine them with the beef broth and optional wine in the skillet, heat through, and melt the cheese as instructed. This method not only saves you time on busy weeknights but also ensures the flavors meld beautifully, resulting in just as delicious meatballs that are perfect for serving to family and friends.
