Creating French Onion Meatballs with Savory Onion Sauce is straightforward when you follow these steps:

1. Preheat the Oven: Heat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

2. Prepare Meatball Mixture: In a large bowl, combine ground beef, breadcrumbs, Parmesan cheese, finely chopped onion, egg, minced garlic, Worcestershire sauce, salt, and black pepper. Mix until well blended.

3. Form Meatballs: Shape the mixture into meatballs, about 1 to 1.5 inches in diameter. Place them on the prepared baking sheet.

4. Bake Meatballs: Bake in the preheated oven for about 20-25 minutes, or until browned and cooked through.

5. Caramelize the Onions: While the meatballs are baking, heat olive oil in a large skillet over medium heat. Add sliced onions and cook, stirring frequently, until onions are caramelized, about 15-20 minutes.

6. Add Broth and Thyme: Pour in the beef broth and add dried thyme to the caramelized onions. Bring the mixture to a simmer.

7. Add Cream: Once the broth is simmering, stir in heavy cream and let the mixture cook for an additional 5 minutes.

8. Combine Meatballs and Sauce: Once the meatballs are cooked, add them to the skillet with the savory onion sauce. Allow them to simmer for another 5-10 minutes, absorbing the flavors.

9. Taste and Adjust: Taste the sauce and season with additional salt and pepper if necessary.

10. Garnish: Serve the meatballs topped with the savory onion sauce and garnish with fresh parsley.

By following these steps, you’ll create a dish that not only tantalizes the taste buds but is also simple enough to prepare on any weeknight.
