How to Make Hearty Ham and Potato Casserole (Step-by-Step)
Follow these simple steps for a creamy, comforting casserole that turns out perfect every time.
Step 1: Prepare the Slow Cooker
Grease the inside of your slow cooker generously with butter.
This adds extra richness and helps keep the potatoes from sticking during slow cooking.
Step 2: Build the First Layer
Place half of the thinly sliced potatoes in the bottom of the crockpot.
Add half of the sliced onion and half of the diced cooked ham on top.
Sprinkle with half of the shredded cheddar cheese.
Step 3: Repeat the Layers
Add the remaining potatoes, onions, and ham to form the second layer.
This creates depth and ensures even cooking and flavor distribution.
Step 4: Mix the Creamy Sauce
In a mixing bowl, whisk together:
Cream of mushroom soup
Milk
Sour cream
Garlic powder
Paprika
Salt
Pepper
This rich and savory sauce binds the casserole together and infuses every layer with creamy goodness.
Step 5: Pour the Sauce Over the Casserole
Evenly pour the sauce mixture over the layered potatoes and ham.
Make sure it seeps into all the spaces to keep the casserole moist and flavorful.
Step 6: Slow Cook to Perfection
Cover with the lid and cook:
LOW: 6–8 hours
HIGH: 3–4 hours
The potatoes should be fork-tender, the ham warmed through, and the sauce thickened.
Step 7: Add the Final Cheese Topping
In the last few minutes of cooking, sprinkle the remaining cheddar cheese over the casserole.
Let it melt into a gooey, irresistible topping.
Step 8: Garnish and Serve
Once everything is melted and bubbly, turn off the heat.
Top with chopped fresh parsley for color and freshness.
Let it rest for a few minutes, then serve warm and enjoy!
