Ingredient Notes

Tuna. I like to get our canned tuna in bulk from Costco; it’s wild albacore tuna by Wild Planet company and very tasty.

Pasta. My favorite kind is gluten-free elbow macaroni pasta by Jovial made with brown rice, but you can use your favorite kind, even egg noodles to turn it into instant pot tuna noodles casserole.

Peas. I used frozen peas left at room temperature for about 15 minutes, but fresh peas would work as well.

Cheese. I like to grate our own cheese and use the large cheddar block from Costco.

Broth. Make sure you use a flavorful broth since it’s a key to having a flavorful meal at the end. Chicken broth or beef broth would work the best for the flavor.

Mayo. When making tuna casserole with mayo, I like to get mayo made with avocado oil, It gives a creamy texture and adds a hint of zing.

Optional. Sliced Baby Bella mushrooms will work great in this recipe. Feel free to add extra veggies, like carrots or green beans.

How to Make Tuna Casserole In Instant Pot

  1. Gather the ingredients. Open canned tuna, drain and mince with the fork while it’s still in the can. In the instant pot add broth, dry uncooked pasta, add drained canned tuna. Don’t stir.
  2. Place a lid on, seal it and turn on high pressure for 4 minutes. Once you hear the beeping sound, following the instant pot instructions do a manual release by turning the knob and safely releasing the air.
  3. Once the pressure is released, open, add mayo, and stir. Spread cheese, stir once more.
  4. Add peas, gently stir one more time without crushing them, and serve. Garnish with dill if desired.

Recipe Tips

Avoid the burn. When making tuna casserole in an instant pot, add the broth to the pot first before adding the rest of the ingredients. Don’t stir the mixture.

Make it creamy. Don’t forget the mayo and cheese. 

Flavor. The mayo adds enough salt to this easy tuna casserole; you might want to add more salt when tasting. If serving to adults, I like to add a tablespoon of Dijon mustard for an extra kick.

More protein. If you would like to have more protein, add three cans of tuna instead.

Storing. Store leftovers in the glass air-tight container in the fridge, reheat before serving.
