I’ve mentioned it before, but it’s worth saying again, I love gnocchi! It’s such a yummy, smooth little puff of potato and adds so much to a meal. I first had it in chicken and gnocchi soup, and haven’t looked back since then.

Over the last few years, I’ve made quite a few recipes using gnocchi in a variety of ways. They can be boiled, fried, sauteed, and baked. The versatility makes it fun to work with. This time, I decided to use them in a casserole with some ham steak and, of course, lots of cheese.

Originally, I set out to make ham steak and gnocchi casserole a recipe for around Easter, but that didn’t pan out. You can either purchase a ham steak for this recipe or use leftover spiral ham.

Ham Steak and Gnocchi Casserole Ingredients

Potato Gnocchi

Potato gnocchi are often found in the pasta aisle at the grocery store. They are small puffs of potato that are very light and fluffy. 

Unsalted Butter

The best butter for this recipe is unsalted. The ham already is high in sodium, so it’s best to use unsalted butter. Of course, salted butter would work, but I would omit the added salt later in the dish if you do. 

Ham Steak

I love buying a ham steak and frying it up for an easy dinner. You can either purchase that or use leftover ham from another recipe.

All-Purpose Flour

The flour is mixed with a little bit of butter to make a roux. This is what helps to thicken the creamy sauce that will go over the casserole. 

Whole Milk

Whole milk works best for this as it has a higher fat content. That said, I have used almond milk before with great success. You could also substitute for heavy cream if needed. 

Salt and Pepper

Every meal needs a little bit of seasoning. If you are worried about the sodium content because of the ham, omit the salt here. But still add the pepper as it adds a lot of flavor to the gnocchi dish. 

Gruyère Cheese

The best way to get gruyere cheese is in a block and shred it yourself. It adds that cheesy goodness to the meal because it melts really well when it’s freshly shredded. 

​Parmesan Cheese

​Just like the gruyere cheese, you are best to purchase this in a block and shred it yourself. 

Green Onions

The easiest way to slice green onions is to use kitchen shears. I like to hold the whole bundle and cut in small increments until I have enough.

    This Gnocchi recipe looks delicious! I am pinning this one to make for the family as I am always looking for somethign new and yummy to make 😉

  4. I have never tried gnocchi before. I definitely want to try this casserole. I really wonder how it will taste, especially with the melted cheese on it.

    1. Hi! I’ve never tried freezing it before, so I’m not positive how it would work. I would try freezing before cooking, though. Prepare it all, then freeze. The only thing that may happen is the gnocchi breaking down a bit as it cooks after being frozen. But, when you go to bake, make sure it goes into the oven before heating as a hot oven can break a cold dish.
