Ingredients

For the Meatballs:

1 ½ pounds ground beef (80/20 blend)

½ cup breadcrumbs (panko or Italian-style)

1 egg, beaten

¼ cup milk

2 cloves garlic, minced

½ teaspoon onion powder

½ teaspoon salt

¼ teaspoon black pepper

½ teaspoon Worcestershire sauce

¼ teaspoon dried thyme

¼ cup grated Parmesan cheese (optional)

For the French Onion Sauce:

2 large onions, thinly sliced

2 tablespoons butter

1 tablespoon olive oil

1 teaspoon sugar

4 cups beef broth

2 tablespoons Worcestershire sauce

1 tablespoon balsamic vinegar (optional)

1 teaspoon dried thyme or 1 tablespoon fresh thyme

1 bay leaf

½ teaspoon salt (adjust to taste)

¼ teaspoon black pepper

1 cup shredded Gruyère or Swiss cheese (for topping)

Instructions

Step 1: Prepare the Meatballs

  1. In a large mixing bowl, combine the ground beef, breadcrumbs, egg, milk, garlic, onion powder, salt, black pepper, Worcestershire sauce, thyme, and Parmesan cheese.
  2. Mix until just combined—do not overmix, as it can make the meatballs tough.
  3. Using your hands or a cookie scoop, form small meatballs (about 1 inch in diameter).
  4. Place them on a baking sheet lined with parchment paper.

Step 2: Sear the Meatballs

  1. Heat a large skillet over medium heat and add a little olive oil.
  2. Sear the meatballs on all sides until browned (about 5 minutes total). This adds depth of flavor and helps them hold their shape in the slow cooker.
  3. Once browned, transfer them to the crock pot.

Step 3: Caramelize the Onions

  1. In the same skillet, melt butter over medium-low heat.
  2. Add sliced onions and cook slowly, stirring often, for about 25–30 minutes until they are deep golden brown.
  3. Add sugar halfway through cooking to help the caramelization process.
  4. Once the onions are caramelized, deglaze the pan with balsamic vinegar (if using), scraping up any browned bits.
  5. Pour the onions over the meatballs in the slow cooker.

Step 4: Make the Sauce & Slow Cook

  1. Add the beef broth, Worcestershire sauce, thyme, bay leaf, salt, and black pepper to the slow cooker.
  2. Cover and cook on low for 6–8 hours or high for 3–4 hours until the meatballs are tender.

Step 5: Add the Cheese & Serve

  1. Remove the bay leaf and stir the meatballs gently.
  2. Sprinkle shredded Gruyère or Swiss cheese on top. Cover and cook for another 10–15 minutes until the cheese melts.
  3. Serve hot, garnished with fresh parsley or thyme.
