🔹️ Ingredients & Their Delicious Purpose

• ✅ 1 packet French onion soup mix – Instantly infuses the beef with savory onion and herb flavor.
• ✅ ½ cup breadcrumbs – Keeps the meatballs soft and perfectly tender.
• ✅ ¼ cup milk – Adds essential moisture for juicy texture.
• ✅ 1 egg – Binds everything together seamlessly.
• ✅ ½ cup grated Parmesan cheese – Boosts umami depth with a nutty, cheesy finish.
• ◾️ For the Gravy & Onions:
• ✅ 2 tablespoons olive oil – Ideal for browning and building flavor.
• ✅ 2 large onions, thinly sliced – The heart of the recipe, caramelized for sweetness and depth.
• ✅ 2 cups beef broth – Creates the savory, rich base for the gravy.
• ✅ 1 tablespoon Worcestershire sauce – Adds tangy, complex undertones.
• ✅ Salt and pepper, to taste – Enhances every element.
• ✅ Fresh thyme (for garnish) – Adds a fragrant, gourmet touch.

🔹️ Step-by-Step Directions

1. 👉 Prepare the Meatballs
   ➡️ In a large bowl, combine ground beef, French onion soup mix, breadcrumbs, milk, egg, and Parmesan cheese. Mix gently until combined (don’t overmix!). Roll into evenly sized meatballs, about 1–1½ inches in diameter.
2. 👉 Brown the Meatballs
   ➡️ Heat olive oil in a large skillet over medium heat. Add the meatballs and brown on all sides — this locks in the flavor. Transfer browned meatballs to your slow cooker.
3. 👉 Caramelize the Onions
   ➡️ In the same skillet, add sliced onions and cook over medium heat for 10–15 minutes, stirring often. When golden and fragrant, layer them over the meatballs in the slow cooker.
4. 👉 Make the Gravy
   ➡️ In a bowl, whisk together beef broth and Worcestershire sauce. Pour over the onions and meatballs.
5. 👉 Slow Cook to Perfection
   ➡️ Cover and cook on LOW for 6–8 hours or HIGH for 3–4 hours. When done, the meatballs will be tender and infused with that luxurious onion flavor.
6. 👉 Finish & Serve
   ➡️ Taste and adjust with salt and pepper as needed. Garnish with fresh thyme. Serve hot — and get ready for rave reviews!
