2 tablespoons butter – Adds richness and depth to the onion mixture.

1 1/2 pounds ground chuck – Opt for a higher fat content for juicy meatballs.

1/4 cup milk – Keeps the meatballs moist and tender.

3/4 cup Italian seasoned breadcrumbs – Acts as a binder and imparts flavor.

5 cloves garlic paste – Infuses the meatballs with garlicky goodness.

1 teaspoon fresh thyme leaves – Adds an aromatic herbaceous note.

1 teaspoon salt – For seasoning the meatball mixture adequately.

1 teaspoon black pepper – A simple spice to bring everything together.

1/2 cup dry red wine – Adds depth and richness to the sauce; choose one you’d drink.

2 cups low-sodium chicken stock – Forms the base for the sauce.

1 teaspoon thyme leaves – Compliments the savory profile of the dish.

How to Make French Onion Meatballs with Savory Onion Sauce

Follow these simple steps to prepare this delicious French Onion Meatballs with Savory Onion Sauce:

Step 1: Prepare the Meatball Mixture
In a large bowl, mix the breadcrumbs and milk together, letting it sit for five minutes. Then, add in the ground chuck, garlic paste, thyme, salt, pepper, and eggs. Mix gently until everything is combined. Don’t overwork it; we want tender meatballs, not hockey pucks!

Step 2: Shape the Meatballs
With slightly damp hands (to prevent sticking), roll the mixture into 1 1/2-inch meatballs. You should get around 15-18 bouncy little beauties. Place them on a parchment-lined baking sheet.

Step 3: Caramelize the Onions
Heat a large pan to medium and add the olive oil, sliced onions, water, and 1/2 teaspoon salt. Cover it up and let the onions cook for about 15 minutes, stirring occasionally. Once they’re soft and translucent, uncover and let them brown to perfection, adding a splash of water if they start to stick.

Step 4: Fry the Meatballs
In an oven-safe frying pan, heat olive oil over medium heat. Add the meatballs in batches, frying until browned on all sides—about three minutes per side. Use a slotted spoon to transfer them to a plate while you finish the sauce.

Step 5: Create the Savory Onion Sauce
In the same pan, pour off excess oil and add the caramelized onions, followed by the butter. Cook until everything is deeply caramelized, then add minced garlic and cook for another minute. Sprinkle in the flour and stir for 1-2 minutes before adding the red wine. Bring to a boil, scraping up any brown bits on the bottom.

Step 6: Assemble and Bake
Pour chicken stock into the mixture, add thyme, and adjust seasoning as needed. Return the meatballs to the pan, top with 3/4 of the Swiss cheese, and pop the pan in a preheated 450°F oven for 7-10 minutes, or until bubbly. Meanwhile, top the toasted baguette slices with the remaining cheese and broil just until melted and golden.

Serve your masterpiece hot, garnished with fresh thyme leaves, and enjoy every succulent bite of these French Onion Meatballs with Savory Onion Sauce. Drizzle that phenomenal sauce over the meatballs and get ready for oohs and ahhs around the table!

Method
 

Preparation
  1. In a large bowl, mix the breadcrumbs and milk together and let sit for 5 minutes.
  2. Add the remaining meatball ingredients to the bowl and mix gently until combined.
  3. With your hands, roll ~1 1/2" meatballs (makes roughly 15-18) and set them on a parchment paper lined baking sheet.
Cooking Onions
  1. Heat a large pan or pot to medium heat and add the olive oil, onions, water, and salt, and mix to coat. Cover with a lid and cook for 15 minutes.
  2. Remove the lid and continue to cook, stirring occasionally. Adjust the heat to avoid burning and add a splash of water if necessary.
Frying Meatballs
  1. Heat a large oven-safe frying pan to medium heat with olive oil to coat the whole pan. Once hot, fry the meatballs until browned (about 3 minutes per side) then remove with a slotted spoon to a dish and set aside.
Caramelizing Onions
  1. Preheat oven to 450°F and set the rack on the middle level.
  2. Pour off the oil used to fry the meatballs and add all of the onions to the pan along with the butter. Cook the onions over medium heat until deeply caramelized, stirring frequently and adding water as necessary.

  4. Add the wine and bring to a boil, scraping the bottom of the pan with a wooden spoon to dislodge brown bits.
