Can I substitute the cream of mushroom soup?

Absolutely! Cream of chicken soup or cream of celery works beautifully. Just note the flavor will shift slightly.

Can I make this casserole dairy-free?

Yes! Use plant-based milk, dairy-free cheese, and vegan butter. The Creamy Winter Vegetable Casserole still turns out silky and delicious.

What’s the best way to store leftovers?

Cool completely, then refrigerate in an airtight container for up to 4 days. It reheats wonderfully—some say even better than the first day.

How can I add protein?

Stir in shredded rotisserie chicken, white beans, or cooked turkey. It becomes a full meal in one pan.

Can I prep this ahead of time?

Definitely. Assemble everything except the breadcrumb topping. Add it just before baking so it stays crisp.

Instructions

Preheat Oven: Set oven to 375°F (190°C). Lightly grease a medium baking dish.
Prep Vegetables:
- For fresh veggies: chop evenly, then steam or blanch 3–4 minutes until just tender. Drain well.
- For frozen veggies: thaw and pat dry to remove excess moisture.
Mix Filling: In a large bowl, combine vegetables, cream of mushroom soup, milk, shredded cheese, dried thyme, garlic powder, salt, and pepper. Mix until all vegetables are coated.
Assemble: Spread the creamy mixture evenly into the baking dish.
Add Topping: Stir breadcrumbs with melted butter until coated. Sprinkle evenly over the top.
Bake: Bake uncovered for 25–30 minutes, or until the top is golden brown and the sauce is bubbling.
Rest & Serve: Let the casserole sit for 5 minutes before serving to allow it to thicken.

Notes

Swap the cream of mushroom soup for cream of chicken or cream of celery for a flavor twist.
To make it dairy-free, use plant-based milk, vegan cheese, and dairy-free butter.
Add cooked chicken, turkey, or white beans for a protein boost.

Make ahead: assemble fully but add the breadcrumb topping just before baking
