Step‑by‑Step Instructions for Cheesy French Onion Meatballs
Step 1: Prepare the Meatballs
In a large bowl, combine the ground beef with minced garlic, salt, and pepper. Mix gently until just combined, then form into bite-sized meatballs, roughly 1.5 inches in diameter. Heat a skillet over medium heat and add olive oil. Brown the meatballs for about 8–10 minutes, turning occasionally until they are golden brown and fully cooked through. Remove from the skillet and set aside.
Step 2: Caramelize the Onions
In the same skillet, add thinly sliced onions and a drizzle of olive oil over medium-low heat. Sauté the onions, stirring frequently, for about 15–20 minutes, or until they are soft and deeply golden. To enhance the sweetness, sprinkle a pinch of sugar and continue to cook, allowing the onions to caramelize perfectly, creating that rich flavor essential for your Cheesy French Onion Meatballs.
Step 3: Make the Savory Sauce
Once the onions are beautifully caramelized, carefully pour in the beef broth. Gently scrape the skillet bottom to incorporate any flavorful bits. Bring to a simmer over medium heat and let it cook for about 5–7 minutes, allowing the sauce to thicken slightly. Taste and adjust the seasoning with salt and pepper, ensuring a balanced flavor for your sauce.
Step 4: Combine Meatballs with Sauce
Return the browned meatballs to the skillet, making sure they are well-coated in the rich onion sauce. Stir everything together gently and let simmer for an additional 5 minutes, ensuring the meatballs absorb some of the savory sauce. The Cheesy French Onion Meatballs will be infused with that delightful onion flavor, making each bite even more irresistible.
Step 5: Melt the Gruyère Cheese
Preheat your broiler while you top the meatball mixture with generous amounts of shredded Gruyère cheese. Cover the skillet and let it cook over low heat for about 3–5 minutes, allowing the cheese to melt beautifully. Once melted and bubbly, transfer the skillet to the broiler for an additional 1–2 minutes for a perfect golden finish. Your Cheesy French Onion Meatballs are now ready to be served!
