Instant Pot Tuna Casserole-–a twist on good old fashioned tuna casserole. Flavors from Mom’s tuna casserole but made easier, faster and without cream of soups.
Instant Pot Tuna Casserole
Was your mom a tuna casserole type of mom? You know when there’s a bunch of kids to feed and the pickings are slim in the refrigerator and she goes to the pantry and grabs a bunch of stuff like tuna, mayo, cornflakes and cream of mushroom soup and puts them all together in a dish and bakes it? There were some nights that my mom was definitely a tuna casserole mom! And now that I’m grown and have a family of my own I get that you can’t always get to the store and sometimes you have to be inventive.
This recipe is a throwback to tuna casserole but it’s made quickly and without any mayo or cream of soups. It’s a bit healthier and it certainly tastes good. I didn’t even tell my kids that it was tuna. I am pretty sure they thought it was chicken. But it does have crushed cornflakes on top…a mom specialty! If you don’t have cornflakes you can also crush up potato chips, also a good choice.
Get all cozy in your snuggie and scoop up a bowl of this Instant Pot tuna casserole for dinner tonight. I bet you’ll really like it!

What Pressure Cooker Did You Use?
To make Instant Pot Tuna Casserole I used my 6 quart Instant Pot Duo 60 7 in 1*. I love this Instant Pot because it has the yogurt making function which I use almost weekly. It has two pressure settings (high and low), and there are also little slots in the handles so that you can rest the lid there instead of putting it down on your counter-top.

A twist on good old fashioned tuna casserole. Flavors from Mom’s tuna casserole but made easier, faster and without cream of soups.
- 1 tsp olive oil
- 1/4 cup diced onion
- 1 large garlic clove, minced
- 1 3/4 cups chicken broth
- 6 ounces uncooked pasta shells (you can also use elbow macaroni)
- 1 cup diced mushrooms
- 1 Tbsp Dijon mustard
- 1 (5 oz) can tuna, drained
- 1 1/2 cups grated sharp cheddar cheese
- 1 cup frozen peas
- 1/2 cup crushed cornflakes or potato chips
- Salt and pepper
- Turn your Instant Pot to the saute setting. When the display says HOT add in the oil and swirl it around. Add in the diced onions and saute for 2 minutes. Then add in the garlic and saute for 20 seconds. Add in the chicken broth and scrape the bottom of the pot. Turn off the Instant Pot.
- Add in the pasta, mushrooms, mustard and tuna.
- Cover the pot and secure the lid. Make sure the valve is set to sealing. Set the manual/pressure cook button to 3 minutes. When the time is up move the valve to venting. Remove the lid.
- Stir in the cheese and peas. Let the pot sit for a minute or two with the lid on top so the peas will warm through and the cheese will melt. It may be a little runny at first but as it sits and you stir it the pasta will soak up the liquid. Salt and pepper to taste.
- Then, if desired, you can pour the pasta into a baking dish and bake the cornflakes/potato chips on top for 5 minutes at 400 degrees F. I used my Mealthy CrispLid* to crisp up the cornflakes. I cooked for 3 minutes at 450.
- Scoop onto plates and enjoy!
This makes a small batch, 4 servings. You can easily double this recipe. Just double all the ingredients and keep the cooking time the same.
