How to Make Baked French Onion Meatballs

  1. Sauté the Onions: Heat olive oil in a large skillet over medium-high heat. Add the onions and sprinkle with salt. Cook for about 30 minutes, stirring occasionally, until they are deeply caramelized and golden brown. Pour in balsamic vinegar and toss in 2 thyme sprigs for an extra burst of flavor, cooking for an additional minute. Transfer the onions to a plate to cool slightly.

  2. Preheat the Oven: As your onions cool, preheat the oven to 410°F (210°C). This will ensure your meatballs bake perfectly.

  3. Chop the Onions: Take half of the cooled caramelized onions and chop them finely. This will help incorporate that sweet flavor throughout the meatballs.

  4. Mix the Ingredients: In a large bowl, combine the ground chicken, ½ cup of shredded mozzarella (or gruyere cheese), bread crumbs, egg, minced garlic, chopped parsley, thyme, salt, and pepper. Gently fold in the chopped caramelized onions, making sure not to over mix.

  5. Shape the Meatballs: Moisten your hands with a little water and shape the mixture into meatballs, about 2 inches in diameter, to make approximately 14 meatballs.

  6. Bake the Meatballs: Place the meatballs in the same skillet used for onions. Generously spray them with cooking oil spray for a golden finish and bake for 12 minutes.

  7. Prepare the Sauce: Remove the skillet from the oven. In a small bowl, whisk together the beef or chicken stock with corn flour until smooth. Pour the mixture over the meatballs, adding the remaining caramelized onions, and top with the rest of the shredded cheese and thyme sprigs.

  8. Finish Baking: Return the skillet to the oven and bake for an additional 15 minutes, or until the meatballs are cooked through—check that the internal temperature reaches 165°F (74°C).

  9. Serve and Enjoy: Remove from the oven and serve immediately with warm crusty bread for dipping in that luscious sauce.

Optional: Garnish with additional fresh thyme for a vibrant touch.

Expert Tips for Baked French Onion Meatballs

Caramelization Magic: Always take your time when caramelizing onions; letting them cook slowly brings out their natural sweetness, enhancing the flavor of your meatballs.

Moisture Check: Avoid over-mixing the chicken mixture; this ensures your meatballs stay tender. If they seem too dry, a splash of broth can help.

Cheese Options: Mixing different cheeses can add extra depth; try a combo of mozzarella and parmesan for a fun twist in your Baked French Onion Meatballs.

Temperature Guide: Use a meat thermometer to check the internal temperature, ensuring your meatballs are cooked through and safe to enjoy.

Sauce Consistency: If the sauce seems too thick, whisk in a bit more broth before baking after adding it to the meatballs for a silkier finish.

How to Store and Freeze Baked French Onion Meatballs

Fridge: Store leftover baked meatballs in an airtight container for up to 3 days. Make sure to cool them completely before sealing to maintain freshness.

Baked French Onion Meatballs Recipe FAQs

What type of onions are best for caramelizing?
You can use white, yellow, or red onions for this recipe. Each variety brings its unique flavor; yellow onions are particularly great for caramelizing due to their natural sweetness. Whichever you pick, aim for firm onions without dark spots or soft spots for the best results.

How long can I store leftover Baked French Onion Meatballs?
Store your leftovers in an airtight container in the fridge for up to 3 days. Make sure the meatballs have cooled completely before sealing to lock in their moisture and flavor. You can enjoy them cold or reheat them for a quick meal!

What should I do if my meatballs are falling apart?
If your meatballs are crumbling, there might be too much moisture or not enough binder. Ensure that you don’t over-mix the chicken mixture. If needed, add a bit more bread crumbs or an extra egg to increase the binding. If the mixture seems dry, a tablespoon of broth can help!

Are there any dietary considerations for Baked French Onion Meatballs?
Yes! If you need gluten-free options, substitute regular bread crumbs with gluten-free alternatives. For a dairy-free version, use dairy-free cheese and ensure your broth is also dairy-free. Always double-check ingredient labels for potential allergens, especially if serving guests with food sensitivities.

How do I know when the meatballs are cooked through?
The best way to ensure your meatballs are fully cooked is to use a meat thermometer. Insert it into the center of one meatball; it should read 165°F (74°C). This step ensures they’re safely cooked while still tender and juicy.
