FAQs
1. Can I make casseroles gluten-free?
Absolutely! Swap regular pasta or breadcrumbs for gluten-free versions, or use quinoa, rice, or cauliflower rice. Double-check broths and sauces too.
2. How long do leftover casseroles stay good in the fridge?
Most keep beautifully 3–4 days. Reheat covered with a splash of broth or milk to keep them moist.

When built with lean proteins, tons of veggies, and controlled portions of cheese or grains—yes! They’re naturally portion-controlled and fiber-rich, which keeps you full longer.

Cover with foil, add a tablespoon or two of broth or milk, and warm at 325°F until heated through. Microwave individual portions work too—just cover with a damp paper towel.
