How to Store and Reheat

Cool the casserole, then store in an airtight container in the fridge for up to 4 days; reheat gently on low in the slow cooker or in a 350°F oven until hot. Freeze leftovers in a freezer‑safe dish for up to 2 months and bake from frozen, adding 15‑20 minutes.

Frequently Asked Questions

Can I make this casserole gluten‑free?

Absolutely – just ensure the brown‑sugar topping uses gluten‑free oats or omit the oats entirely; all other ingredients are naturally gluten‑free.

What’s the best way to keep the topping crisp?

Add the topping during the last 30 minutes of cooking and keep the slow cooker’s lid slightly ajar, or finish under the broiler for a minute.

Can I substitute sweet potatoes with pumpkin?

Yes, roasted pumpkin works beautifully and offers a slightly earthier flavor; adjust the spices to taste.
