Frequently Asked Questions
Can I freeze this casserole?
Yes, assemble and bake as directed, then cool completely. Wrap tightly and freeze up to 3 months. Thaw overnight before reheating.
What cheese works best?
Fresh mozzarella or a sharp provolone blend adds extra flavor. Feel free to mix for a richer taste.
Can I use almond meal instead of almond flour?
Almond meal works, but it’s coarser. Your meatballs may be slightly denser, so handle gently.
How do I reheat leftovers?
Reheat individual portions in the microwave for 1–2 minutes or in a 350°F (175°C) oven until warmed through.
