Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, you can prepare the casserole in advance and refrigerate it before baking. Just cover it tightly with plastic wrap or foil. When ready to bake, remove the cover and add a few extra minutes to the baking time to ensure it’s heated through.

Can I use fresh peas instead of canned?

While canned peas are convenient, you can certainly use fresh peas. Just blanch them briefly in boiling water before adding them to the casserole to ensure they cook properly. This will enhance the texture and flavor of your dish.
