This Ham Tetrazzini is creamy, cheesy, and always a family favorite dinner with leftover ham, too! Spaghetti is baked with ham and veggies in a savory cream sauce and topped with melty cheddar.

You’ve probably had chicken tetrazzini, and maybe even turkey tetrazzini, but what about ham tetrazzini? If this recipe is new to you, you need to give it a try—especially if you have some leftover ham on hand!

Ham Tetrazzini Recipe

Like a traditional tetrazzini, this ham tetrazzini recipe starts with spaghetti. You’ll stir this into a creamy, cheesy sauce, along with sautéed mushrooms, onions, and peas. The primary difference between this recipe and chicken tetrazzini is the addition of ham, which adds so much savory, salty flavor. 

You can use any type of ham you like or have on hand for this recipe. Store-bought ham? Yes! Baked Ham with Maple Dijon Glaze? That works too! Even the honey baked ham you have leftover from Easter is great in ham tetrazzini.

I love this recipe for a weeknight dinner, but ham tetrazzini is also the kind of dish that will disappear if you bring it to a potluck—and I guarantee everyone will be asking you for the recipe before you leave! You can also assemble it ahead of time and bake it later if you’re short on time during the week.

How to Make Ham Tetrazzini

1. Prepare

Preheat your oven to 350ºF. Cook the spaghetti according to the package directions in salted water.

Melt the butter in a large skillet and add the onion and mushrooms. Cook until the onion is soft and the mushrooms are browned.

3. Finish the Sauce

Add the soup, milk, salt, and pepper to the skillet and stir to combine. Next, add the ham, peas, ¾ cup cheddar cheese, and Parmesan cheese. Stir and cook over medium heat until the cheese is melted. Taste and add salt, if desired.

    I’m preheating the oven now, and I know this is going to be delicious just from licking the spoon! I didn’t have fresh mushrooms, so I used jarred. Don’t expect that to be a big deal. One thing that I noticed … at the beginning of the directions, it says preheat to 350, then at the end it says bake at 375. Since most casseroles I do are at 375, I went with that.

    1. Thank you for catching that! It can be baked at 350 or 375, but it might be done a little faster at 375. 🙂 We’ve corrected the recipe.
