  • It’s a balanced family-friendly recipe that can feed the whole family, including picky kids.
  • This recipe is made without the cream of mushroom soup.

Key Ingredients

ingredients to make pasta in the instant pot

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 elbows pasta by Jovial made with organic brown rice, but you can use your favorite kind.

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 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 or beef would work the best for the flavor.

Mayo. It gives a creamy texture and adds a hint of zing.

Optional. Sliced Baby Bella mushrooms will work great in this recipe.

How To Make It

Step 1. You will need to add ingredients to the pot.

Step 2. Place a lid on and seal the pot. Turn on high pressure for 4 minutes, following the manual release.

Step 3. Once the pressure is released, add mayo, cheese, and peas. Garnish and serve.

Avoid the burn. 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; you might want to add more salt when tasting. 
More protein. If you would like to have more protein, add three cans of tuna instead.
