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.
-
Layer half of the sliced russet potatoes at the bottom of the greased baking dish. Next, add half of the diced ham, followed by half of the creamy soup mixture. Repeat this layering until all ingredients are used. It’s like building a delicious tower of comfort!
-
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.
-
Uncover and bake for an additional 15 minutes until the top is golden brown and bubbly. This finishing touch gives your casserole that irresistible cheesy crust.
-
Cool for a few minutes before serving. This allows the casserole to set slightly, making it easier to scoop and enjoy every delicious layer.

Make Ahead Options
These Ham and Potato Casserole is perfect for busy home cooks looking to save time! You can prep the entire casserole up to 24 hours in advance. Start by assembling the layers of potatoes, ham, and the creamy soup mixture in your greased baking dish, then cover it tightly with plastic wrap or aluminum foil to prevent drying out. When you’re ready to cook, simply remove the cover, add the shredded cheddar on top, and bake directly from the fridge; just add an extra 10-15 minutes to the original baking time to ensure it heats through thoroughly. This way, you’ll have a comforting, home-cooked meal ready to enjoy with minimal effort on a hectic day!
Chef's Helpful Tips
- When making Ham and Potato Casserole, ensure your potatoes are sliced evenly for consistent cooking; a mandoline can make this task easier.
- Avoid using low-quality canned soup, as higher-quality options significantly enhance the flavor of the dish.
- Be careful not to overbake the casserole, as this can lead to dry potatoes; once the cheese is golden and bubbly, it’s time to take it out.
- Letting the casserole rest before serving helps with slice integrity, making it easier to serve and enjoy.
Ham and Potato Casserole Recipe FAQs
What kind of potatoes are best for Ham and Potato Casserole?
For this casserole, I recommend using russet potatoes, as their creamy texture absorbs the savory mushroom sauce beautifully. If you prefer a waxy variety, Yukon Golds are also an excellent choice—they hold their shape well and have a delightful flavor.
How can I properly store leftover Ham and Potato Casserole?
Store your leftover casserole in an airtight container in the fridge for up to 3 days. This ensures it stays fresh and maintains its delicious flavors. You can also freeze it for up to 3 months by tightly wrapping it in plastic wrap and aluminum foil—just make sure you label it, so it doesn’t get lost in the freezer!
Can I freeze Ham and Potato Casserole?
Absolutely! To freeze, allow the casserole to cool completely, then wrap it tightly with plastic wrap and again with aluminum foil to prevent freezer burn. It’s best to thaw it in the fridge overnight before reheating, which helps it maintain its creamy consistency. When ready, just pop it in a preheated oven at 350°F (175°C) for about 20-30 minutes, until warmed through.
What should I do if my potatoes are browning before cooking?
If you notice any dark spots on your potatoes while slicing, it’s best to discard those parts, as they can affect the dish’s taste and texture. To prevent browning, you can soak the sliced potatoes in cold water until you’re ready to layer them in the casserole. This keeps them fresh while you’re prepping!
Can I use low-fat or non-dairy alternatives in my Ham and Potato Casserole?
Certainly! If you’re looking for lighter options, you can substitute the whole milk with low-fat milk or even unsweetened almond milk for a non-dairy version. Just keep in mind that non-dairy alternatives may slightly alter the flavor and creaminess of the casserole.
