Step 1: Prepare the Meatballs

  1. In a large bowl, mix ground beef, breadcrumbs, Parmesan, egg, garlic, onion powder, Italian seasoning, salt, and pepper.

Step 3: Make the French Onion Sauce

  1. In the same skillet, melt butter. Add sliced onions and sprinkle with sugar.
  2. Cook over medium-low heat, stirring often, until caramelized (15–20 minutes).
  3. Sprinkle flour over the onions and stir to coat.

  • Comfort Meal: Over buttery mashed potatoes with roasted vegetables on the side.
  • Italian Twist: Toss with pasta for a hearty baked-meatball pasta dish.

Recipe Variations

  • Cheese Swap: Try mozzarella or provolone if you don’t have Gruyère.
  • Lightened-Up: Use ground turkey or chicken instead of beef.
  • Gluten-Free: Use gluten-free breadcrumbs and flour alternatives.
  • Extra Flavor: Add a splash of balsamic vinegar while caramelizing onions.

Make-Ahead Tips

  • Meatballs: Prepare and refrigerate up to 24 hours before cooking.
  • Caramelized Onions: Cook and store in the fridge for 2–3 days.
  • Freezer Friendly: Freeze cooked meatballs and sauce (without cheese) for up to 3 months. Thaw, reheat, and add cheese before serving.

Notes

  • Caramelizing onions takes time — don’t rush the process, as it builds the signature flavor.
  • Use a large, oven-safe skillet so you can transfer straight from stovetop to broiler.
  • For a thicker sauce, let it simmer uncovered for an extra 5 minutes before adding the meatballs.

FAQ

Can I make this without wine?
Yes, simply substitute extra beef broth for the wine.

What cheese works best?
Gruyère is traditional for French onion soup, but Swiss, provolone, or mozzarella also work.

Can I bake the meatballs instead of frying?
Definitely — bake at 400°F (200°C) for 18–20 minutes, then transfer to the sauce.

How do I store leftovers?
Refrigerate in an airtight container for up to 3 days or freeze for 3 months. Reheat gently on the stovetop or in the oven.
