Step 1: Start by placing the potatoes into a large pot and covering them with salted water. Bring it to a boil over high heat. Once boiling, reduce the heat to medium-low and let the potatoes simmer until tender, about 10 to 15 minutes.

Step 2: While the potatoes are cooking, preheat the oven to 350F (175C) and grease a 1 -quart baking dish to prepare it for the casserole.

Step 3: In a skillet, melt 3 tablespoons of butter over medium heat. Add the ham and chopped onion, cooking and stirring until the onion turns translucent and soft, about 5 minutes. Once done, remove from the heat.

Step 4: Drain the cooked potatoes and add them to the ham and onion mixture. Stir them together to combine. Transfer this mixture into the prepared baking dish.

Step 5: In a saucepan, melt the remaining 4 tablespoons of butter over medium heat. Whisk in the flour and cook, stirring constantly, until the mixture turns light golden brown and forms a paste, about 5 minutes.

Step 6: Gradually whisk in the milk to the flour mixture. Season with salt and pepper to taste. Continue stirring until the sauce thickens, about 2 minutes.

Step 7: Reduce the heat to medium-low and stir in the shredded Cheddar cheese until its fully melted into the sauce. Pour the cheesy sauce over the potato and ham mixture in the baking dish.

Step 8: Sprinkle the bread crumbs evenly over the top of the casserole.

Step 9: Place the casserole in the preheated oven and bake for 25 to 30 minutes, or until the sauce is bubbly and the top is golden brown.

I made this dish using leftover Easter ham from a week ago. Initially, I was unsure about it, but decided to give it a try. To my surprise, my family, who are quite picky eaters, absolutely loved it! There wasn't a single crumb left on anyone's plates. Thank you for this delicious recipe. I followed it exactly as written and it turned out perfect!

I tried this recipe with a slight variation to make it a one-pot meal. Using my dutch oven, I cooked the onions in butter, then added 3 cups of chicken stock instead of milk, followed by the ham and cubed potatoes. After the potatoes were cooked, I drained them, reserving 1 1/2 cups of broth. I thickened the sauce with flour and added the cheese. I combined the potatoes and ham back into the dutch oven, covered them with the sauce, and baked as directed. The result was fantastic.

I decided to enhance the flavor by adding a touch of garlic to the onions and noticed it needed some more vibrant color. To brighten up the dish, I threw in some diced broccoli, because let's be real, what pairs better with cheese than broccoli?

I enhanced the dish by including 2 cups of freshly sliced mushrooms. Additionally, I ended up using around 3 cups of milk in total as I felt the consistency was a bit too thick with just the 1.5 cups recommended in the recipe. Overall, the outcome was really delicious!

This dish turned out really well! I used red tomatoes without peeling them. I had to use a larger pot because it made a lot of sauce. I even made some extra sauce to pour over it.

Creamy and delicious! This casserole bakes in just 30 minutes once everything is prepared. I'll definitely be saving this recipe for when I have leftover ham.

I added some garlic to the ham mixture for extra flavor, and a couple of pinches of MSG to enhance the cheesy goodness in the sauce. The dish would have been delicious on its own, but I made some tweaks to suit my family's preferences.

This recipe was fantastic and incredibly simple to prepare! I followed the advice of previous reviewers and decided to amp up the seasoning, including garlic powder and extra salt and pepper.

I had high hopes for this dish but unfortunately, it didn't turn out as expected, mostly due to my own mistakes. I decided to add celery and leftover asparagus, which added a nice touch, but the cheese sauce didn't quite melt evenly into the potato and ham mixture. Instead, it just sat on top of the casserole. I realize now that I should have thinned it out with more milk to improve the consistency. Overall, the dish was lacking in flavor, though my kids surprisingly enjoyed it. They ended up drowning it in ketchup, which made it more palatable for them. I may have also added too much ham, though I didn't think that was possible considering others had suggested using more. While my kids ate it, I'm not sure if I would make it again. I had hoped for a better outcome. Now I'm stuck with leftovers that I doubt anyone will touch, which feels like a huge waste of ingredients.

Great experience! I'm baking it now and loving the ingredients. I added some bone soup for moisture, along with Parmesan and a dressing with garlic for extra flavor. Seems like this recipe is a keeper. I love casseroles - so much easier than cooking for 3 hours!

I recently enhanced the flavor of my dish by incorporating sweet red pepper and chili powder. This recipe definitely required my husband's expertise in making a delicious gravy.
