Storage and reheating tips
To store leftovers, place them in an airtight container and refrigerate for up to three days. When you’re ready to enjoy it again, simply reheat in the microwave or oven. If you’ve made a larger batch, consider freezing portions for future meals. It can be safely frozen for three months.
Helpful cooking tips
For an extra flavor boost, try browning the meatballs in a pan before adding them to the casserole. This not only enhances the taste but also creates a bit of texture. Keep an eye on your cooking time, as ovens may vary.
Creative twists
Experiment with adding different vegetables, like spinach or mushrooms, for added nutrition and flavor. If you prefer a different cuisine twist, consider using barbecue sauce instead of marinara for a unique flavor profile.
