How to Make Ham and Potato Casserole

Preheat your oven to 375°F (190°C). Preheating helps to create that perfectly creamy texture while the casserole bakes. Don’t forget to grease your baking dish to prevent sticking!

Mix the cream of mushroom soup and whole milk in a bowl until smooth. Season it with garlic powder, dried thyme, salt, and pepper. This mixture forms the velvety base that ties all the flavors together beautifully.

-
Top your casserole with the grated sharp cheddar cheese. Cover the dish with aluminum foil, which will help keep everything moist as it bakes. Pop it in the preheated oven and bake for 45 minutes.

Ham and Potato Casserole Recipe FAQs
What type of potatoes should I use for this recipe?
For this Ham and Potato Casserole, I recommend using medium russet potatoes. They are starchy and creamy when baked, providing the perfect texture to complement the rich flavors of the casserole. If you’re looking for an alternative, Yukon Golds can also work beautifully, offering a slightly buttery taste.
How should I store leftover Ham and Potato Casserole?
Absolutely! Any leftovers should be stored in an airtight container in the fridge for up to 3 days. Make sure it cools down to room temperature before you cover it to prevent moisture buildup, which could make the casserole soggy. When you’re ready to enjoy it again, you can reheat it in the microwave or in the oven until heated through.
Can I freeze Ham and Potato Casserole?
Yes, you can! Just wrap the casserole tightly in plastic wrap and then in aluminum foil to keep it fresh. It can be frozen for up to 2-3 months. When you’re ready to eat it, simply thaw it overnight in the fridge. To reheat, place it in a covered dish in the oven at 350°F (175°C) for about 30-45 minutes, or until heated through. You may want to add a bit of extra cheese on top to revitalize that gooey cheesiness!
What if my casserole is too watery after baking?
If your Ham and Potato Casserole turns out watery, this can happen if the potatoes released extra moisture or the soup was too thin. To remedy this, you can try draining some of the liquid before serving and adding a little cornstarch mixed with water to the remaining mixture in the casserole dish to help thicken it up. Next time, ensure the potatoes are sliced evenly and you can reduce the milk slightly, too.
Are there any dietary considerations for this recipe?
This casserole contains dairy and gluten, so if you or your guests have allergies, consider using gluten-free cream of mushroom soup and lactose-free milk. For a vegetarian version, swap out the ham for a medley of sautéed vegetables like bell peppers or mushrooms, ensuring you have a hearty veggie mix to keep that comforting essence. You may also want to check the cheese label for any allergens if you’re serving others.
