Ham tetrazzini is a fun and tasty way to mix up the classic dish with an entirely new ham-filled experience. Creamy baked noodles, ham, and peas bring together a dish that is filling and enjoyable.

This dish has pretty much everything you need for a complete meal already thrown together in the instant pot.
Adding a small side salad and a slice of warm garlic bread can really help to diversify your plate and make the dish stretch further for larger families (or if you just want leftovers for lunch the next day).
One of the added perks of this dish is that it allows you to use up any leftover ham that you may have on hand.
After the holidays we often have a few pounds of cooked ham that needs to be used, but eating it plain gets boring.

Then you add in that after splurging on the holiday meal there is little money left in the grocery budget for the remainder of the pay period, so you’re looking for frugal recipes too.
This leftover ham recipe is perfect for helping to use up the last of that honey glazed ham, but if you still find yourself with more ham than you can handle, you can always freeze it in portioned bags or choose to make more ham-filled meals like my cheesy scalloped potatoes with ham.

What's in Ham Tetrazzini

- 2 Tb Butter
- 1 Tb Garlic
- 8 oz Mushrooms

How to make Ham Tetrazzini
- Turn your instant pot to saute mode and heat it until it’s hot.
- Add in the butter, garlic, and diced onion. Saute the onion until it begins to turn translucent.
- Add in the sliced mushrooms and saute for another minute.
- Turn off the instant pot
- Add in the broth and deglaze the bottom of the pan if necessary.
- Break spaghetti noodles in half and lay about ⅓rd of the noodles across the bottom of a pan, then lay another ⅓of the noodles criss-cross over the top of that layer.
- Top of the noodles criss-cross on top of those noodles and do not stir.
- Add the heavy cream, do not stir.
- Add in your ham cubes, and once again, do not stir.
- Set the cooker to manual for 4 minutes and allow for a 3 minute natural release. After that is up, do a quick release for the remaining pressure.
- Stir the pasta and ham together.
- Add in the peas, sour cream, and cheese.
- Stir everything to combine and then close the lid for 1 minute to allow it to heat through.
- As an added option you can also choose to transfer the mix to a casserole dish and place french onions on the top and then bake it at 350 degrees for 5 minutes.
- Enjoy!

Can I bake Ham tetrazzini?
Yes, you can! You can make the dish using a large sauce pan on the stove, following the same instructions as with the instant pot and then just pour the mixture into a 9x12 baking dish.
You can then bake it at 350 degrees for up to 30 minutes, depending on how crunchy you want the top to be.
How to reheat Ham Tetrazzini?
You can reheat ham tetrazzini in the microwave or on a pot on top of your stove. You may find that adding a tablespoon of butter or a small amount of cream helps to prevent the noodles from drying out as it reheats.

What if I don't have Leftover Ham?
If you don’t have leftover ham on hand, you can actually buy a pre-cooked ham at the grocery store.
Not only do you have the option of buying already chopped ham, but you can also pick a ham steak (which is normally cheaper) and dice it up yourself.

How long is Ham Tetrazzini good for?
If you store leftovers in the fridge in an airtight container, you can expect them to last up to a week and be just fine.
I wouldn’t push it past 4 days though as the dish may not taste as great as it did when it was fresher. That being said, you can also wrap and freeze the dish for longer storage if you can’t eat your leftovers fast enough.
Can I leave out the peas?
Absolutely! While the peas do add a little veggie and textural difference in the dish, you can leave them out if you’re not a fan!
You can even substitute the peas for finely chopped broccoli or spinach if you want the dish to still contain something green and healthy.

super simple, only prep work was garlic and onion. Pasta was VERY flavorful; we added the fried onions. Definitely best way to use up leftover holiday ham!!

Hi Corinne! Thanks for a fantastic review! I so appreciate hearing your feedback. Making Instant Pot Ham Tetrazzini is a great way to use up leftover ham for sure!
Angela Smith
I made this for dinner tonight. The flavor was delicious, but it was very runny. Any recommendations? Less broth? More noodles?
Devour Dinner
Hi Angela, I find as this recipe cools the sauce thickens. I hope you found that as well.
