Step‑by‑Step Instructions for Cheesy French Onion Meatballs
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C) to create the perfect cooking environment for your Cheesy French Onion Meatballs. This will ensure they bake evenly and develop a delicious golden-brown exterior. While the oven heats, gather your baking sheet, as you’ll soon be placing the meatballs on it for an easy transition to the oven.
Step 2: Prepare the Meatball Mixture
In a large mixing bowl, combine ground beef, breadcrumbs, egg, and seasonings such as salt, pepper, and garlic powder. Use your hands to mix the ingredients gently until just combined, being careful not to overwork the meat. Once mixed, shape the mixture into 1-inch meatballs and arrange them neatly on your prepared baking sheet.
Step 3: Bake the Meatballs
Place the baking sheet in the preheated oven and bake the meatballs for about 20 minutes. You’ll know they’re ready when they are browned and firm to the touch. Allowing them to bake properly is crucial for achieving a tender interior that harmonizes beautifully with the sauce, making these Cheesy French Onion Meatballs irresistible.
Step 4: Caramelize the Onions
While the meatballs are baking, heat a skillet over medium heat and add a splash of oil. Add the sliced onions, stirring occasionally to avoid burning. Cook for about 20-25 minutes until they soften and turn a deep golden brown. To enhance the sweetness, add a touch of honey midway through cooking, ensuring the onions become richly caramelized.
Step 5: Create the Onion Sauce
After the onions are beautifully caramelized, pour in the beef broth to create a savory sauce. Stir and bring the mixture to a gentle simmer, allowing the flavors to meld together for a few minutes. This rich sauce will envelop the meatballs with a comforting, heartwarming flavor that defines your Cheesy French Onion Meatballs.
Step 6: Combine Meatballs and Sauce
Once the meatballs are cooked through, carefully add them to your onion sauce in the skillet. Stir gently to coat the meatballs evenly, and let them simmer together for an additional 5-10 minutes. This step infuses the meatballs with the sweet and savory flavors of the sauce, enhancing the overall taste of the dish.
Step 7: Melt the Cheese
To finish off your Cheesy French Onion Meatballs, transfer them to a serving dish and generously top them with shredded Gruyère cheese. Place the dish under the broiler for just a few minutes until the cheese is bubbly and golden. Keep a close eye on it to prevent burning, ensuring a perfect melt that adds a delightful finish to this comforting dish.

Absolutely, for the sweetest flavor, I recommend using yellow onions as they caramelize beautifully, creating a rich, deep flavor.
