How to keep leftovers fresh
- Refrigerator: Store cooled leftovers in an airtight container for 3–4 days.
- Freezer: Freeze meatballs and sauce in a freezer-safe container for up to 3 months. Thaw in the fridge overnight before reheating.
- Reheat gently in a saucepan over low heat or in the microwave until warm.
Small tips to get the best results
- Don’t overwork the meat when mixing — mix until just combined to keep meatballs tender.
- Brown the meatballs quickly in a skillet first if you want a slightly firmer crust (optional).
- If the sauce seems thin after cooking, remove the lid and cook on high for 15–30 minutes to reduce it.
- Taste and adjust salt before serving, especially if your French onion soup is salty.
Simple variations to try
- Use a mix of beef and pork for richer flavor.
- Add a tablespoon of Worcestershire sauce to the meat mixture for depth.
- Swap mozzarella for Swiss or provolone to change the cheese character.
- Make them smaller for appetizers or larger for sandwich-style servings.
