Why This French Onion Meatballs and Rice Is a Weeknight Winner
- Only 10 minutes of prep – then the oven does the rest.

- Frozen meatballs save the day – no need to roll your own.
- Melty, cheesy topping – Gruyère takes it over the top.
Tips for the Best French Onion Meatballs and Rice
- Don’t thaw the meatballs – add them straight from the freezer. They’ll cook perfectly in the oven.
- Use long-grain white rice – basmati or jasmine work well. Avoid instant rice, brown rice, or short-grain rice, as they require different liquid ratios and cook times.
- Cover tightly with foil – this traps steam and ensures the rice cooks evenly. No peeking!
- Check rice doneness – if the rice is still slightly firm after 40 minutes, cover and bake for 5–10 more minutes before adding the cheese.
- Make it extra onion-y – caramelize a sliced yellow onion in a skillet while the casserole bakes, then sprinkle it over the top before adding the cheese.
- Gruyère is traditional – but Swiss, provolone, or mozzarella work well if Gruyère is hard to find.
What to Serve With French Onion Meatballs and Rice
This casserole is a complete meal, but these sides pair beautifully:
- Steamed green beans or roasted asparagus
- Simple side salad with a tangy vinaigrette
- Crusty baguette (for soaking up any extra sauce)
- Glass of red wine (like Pinot Noir or Merlot) for the adults
Storage & Reheating
- Fridge: Store leftovers in an airtight container for up to 4 days.
- Freezer: Freeze the fully baked and cooled casserole for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheat: Reheat in a 350°F oven for 15–20 minutes (covered with foil for the first 10 minutes). Microwaving individual portions works but may make the rice slightly softer.
