👩‍🍳 Step-by-Step Beginner-Friendly Instructions

1. Form meatballs: Mix beef, breadcrumbs, Parmesan, egg, garlic powder, onion powder, salt, and pepper. Roll into 1-inch balls.
2. Sear meatballs: Heat olive oil in a skillet over medium heat. Sear meatballs for 2–3 minutes per side until browned (they’ll finish cooking in the sauce) 🥩. Remove and set aside.
3. Caramelize onions: In the same skillet, melt butter and olive oil. Add onions and sugar, cooking 20–25 minutes, stirring often, until golden brown 🧅.
4. Build the sauce: Add garlic and cook 1 minute. Deglaze with white wine (or broth), scraping up any browned bits. Stir in beef broth, thyme, salt, and pepper. Simmer 5 minutes.
5. Add meatballs: Return meatballs to the skillet, nestling them into the sauce. Cover and simmer 10 minutes until cooked through.
6. Cheese topping: Sprinkle shredded Gruyère or mozzarella over the top. Cover until melted, or broil briefly until bubbly 🧀.
7. Serve: Enjoy hot with mashed potatoes, pasta, or crusty bread for soaking up the sauce.

💡 Pro Tips

• Make-ahead onions: Caramelize onions up to 2 days in advance to save time.
• Cheese swaps: Provolone, Swiss, or mozzarella all work if Gruyère isn’t handy.
• Meal prep: Freeze cooked meatballs (without cheese) for up to 2 months. Add cheese after reheating.
• Serving idea: Perfect over creamy mashed potatoes or toasted baguette slices for that classic French onion soup vibe.
