Tips & Variations

Use freshly shredded chicken if you prefer, but rotisserie chicken adds convenience and great flavor.
For a lower sodium option, use reduced-sodium soups and broth.
Add mushrooms or sautéed onions for extra texture and flavor.

Swap green beans for peas or mixed vegetables to vary the veggies.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm individual portions in the microwave or reheat the entire casserole in a 350°F oven until heated through. Avoid freezing this casserole as the texture may change.

FAQs

Can I make this casserole ahead of time?

Yes, you can assemble the casserole up to a day in advance, cover it tightly, and refrigerate. Bake just before serving, adding a few extra minutes to the cooking time if baking from cold.

What can I use instead of Lipton Onion Soup Mix?

If you don’t have Lipton Onion Soup Mix, you can make your own blend using dried onion flakes, beef bouillon powder, onion powder, and herbs as a substitute.
