Step‑by‑Step Instructions for Slow Cooker Ham and Potato Casserole

Step 1: Prep Ingredients
Begin by washing and peeling your potatoes, then cutting them into bite-sized cubes. In a large mixing bowl, combine these cubed potatoes with the chopped cooked ham, shredded cheddar cheese, and diced onion. Mix everything gently but thoroughly, ensuring that each ingredient is well distributed—this will create the delicious base for your Slow Cooker Ham and Potato Casserole.

Step 2: Mix Sauces
In a separate bowl, whisk together the sour cream, cream of mushroom soup, milk, minced garlic, salt, black pepper, and dried thyme. This creamy mixture will add richness to your casserole. Take your time mixing until it’s smooth and well blended; this ensures that the flavors meld perfectly as they slow cook together in the next step.

Step 3: Combine Mixtures
Carefully pour the creamy soup mixture over the potato and ham mixture. Use a spatula to gently fold everything together, making sure all the potatoes and ham are coated evenly in the sauce. This step is crucial for achieving the delightful creamy texture that defines your Slow Cooker Ham and Potato Casserole and prevents any dry bites.

Step 4: Transfer to Slow Cooker
Lightly grease the inside of your slow cooker to prevent sticking. Then, pour the entire mixture into the slow cooker, spreading it out evenly with a spatula. Make sure it’s level so that it cooks uniformly. This set-up is key for allowing the flavors to meld and the potatoes to become tender as they simmer over the next several hours.

Step 5: Cook
Cover your slow cooker with the lid and set it to cook on low heat for 6 to 8 hours. This gentle cooking process allows the flavors to develop beautifully. You’ll know it’s ready when the potatoes are fork-tender and the casserole is bubbling slightly at the edges. Resist the urge to lift the lid too often, as this will slow down cooking.

Step 6: Garnish & Serve
Once the cooking time is complete, carefully open the lid and stir the casserole gently to redistribute the creamy sauce. If you’d like, sprinkle freshly chopped parsley on top for a burst of color and freshness. Serve your Slow Cooker Ham and Potato Casserole hot, inviting family and friends to gather around and enjoy this comforting dish together!

Slow Cooker Ham and Potato Casserole Recipe FAQs

What type of potatoes work best for this casserole?
Absolutely! I recommend using a mix of russet and Yukon gold potatoes for the best creaminess and flavor. Russet potatoes break down beautifully while Yukon golds add a nice buttery taste. Avoid using waxy potatoes like red or fingerling, as they may not soften adequately during the slow cooking process.

How should I store leftovers from the casserole?
For sure! Store leftover Slow Cooker Ham and Potato Casserole in an airtight container in the fridge for up to 3 days. It’s essential to let the casserole cool completely before sealing it to prevent moisture buildup. When you’re ready to enjoy it again, simply reheat in the microwave, adding a splash of milk to keep it creamy.

Can I freeze the ham and potato casserole?
Very much! You can freeze the casserole for up to 2 months. To freeze, first, allow it to cool to room temperature. Then, portion it out into freezer-safe containers or heavy-duty freezer bags, squeezing out excess air to prevent freezer burn. When you’re ready to eat, thaw overnight in the fridge and reheat in the microwave or stovetop—remember to add a splash of milk for moisture!

What if I want to make this casserole vegetarian?
Of course! To make a delicious vegetarian version, simply omit the ham and replace it with hearty vegetables such as mushrooms or bell peppers. You can also add peas for a touch of sweetness. Swap the cream of mushroom soup with a vegetable broth-based alternative to maintain that creamy texture, and enjoy a dish that’s just as comforting!

How can I avoid the casserole being too dry while cooking?
A great question! To ensure your Slow Cooker Ham and Potato Casserole remains moist and creamy, make sure your potatoes are well coated in the creamy mixture before cooking. Consider adding extra milk or a bit more sour cream if you prefer a creamier texture. And, resist the urge to lift the lid too often during cooking; each time you do, steam escapes and can dry out your dish.

What’s the best way to reheat the casserole?
Absolutely, reheating is a breeze! If you’re reheating leftovers from the fridge, pop a portion in the microwave for a quick warm-up. Add a splash of milk to keep it moist and stir halfway through for even heating. If you’re thawing from frozen, allow it to defrost in the fridge overnight first, then reheat on the stovetop over low heat, stirring occasionally until warmed through. Enjoy!
