Instant Pot Tuna Casserole is a delicious and hearty comfort meal ready to eat in less than 30 minutes. Made with simple flavorful ingredients using pantry staples already in your kitchen, this easy one-pot meal is a budget-friendly dinner that everyone will love!

Have this Instant Pot Tuna Casserole in your family’s dinner rotation and you’ll always have a great tasting backup plan on days where time seems to get away from you!  If you are looking for other quick and easy Instant Pot recipes for busy weeknight meals or when you’re serving a crowd Instant Pot Shrimp Scampi and Instant Pot Pot Roast are also two of my family’s favorites!

Making a homemade tuna casserole has never been easier. You’ll be pleased to know making it in a pressure cooker is so much faster than what you’re used to! If you have never made it before, well then you’re just in for a treat!

This casserole is made with mouthwatering flaky tuna, noodles, and peas, in a creamy cheesy sauce. It’s seasoned with spices and a hint of dill which provides all of the flavors in every single bite.

This is a lifesaver if you need to make a filling meal in a pinch. Having everyone gather around the table to share a nutritious warming meal is made that much better when you know everyone is satisfied.

Make a big batch and freeze some for later. It will keep in the fridge for a few days and it makes great leftovers to pack in your lunch the next day.

How to make Tuna Casserole in the Instant Pot

To start, turn on your Instant Pot to saute mode. Heat up for a couple of minutes then add in the oil and butter until butter has melted.

Add in onions and saute until completely cooked. Then add in chicken broth, salt, pepper, garlic powder, onion powder, dill, and milk and mix together.

Place the egg noodles on top of the liquid mixture but DO NOT STIR. You’ll notice you will be adding ingredients in layers at this point. The reason for this is because if the noodles soak up the liquid too quickly, you will get a burn notice.

Add the solid white albacore tuna to the top of the noodles. Again, DO NOT STIR.

On top of the tuna, you’ll add the cream of mushroom soup, spreading evenly over the tuna but not stirring!

Put the lid on the pot and close the pressure valve on top and make sure the valve is on seal. Set the Instant Pot to Manual or Pressure for 3 minutes.

When the timer goes off, release the pressure carefully using a tea towel. You don’t want to leave it to release manually as this may cause everything to become mushy.

Once the pressure has been released, open the pot and add the frozen peas and shredded cheddar and stir to combine.

Tips and Variations

  • Avoid the burn message on your instant pot by layering the ingredients and not stirring everything together. You don’t want the pasta soaking up the liquid too soon.
  • Use solid white albacore tuna or tuna in water rather than oil because it’s got a milder flavor.
  • Use half and half, full cream, or a non-dairy alternative. The half and half will give it an extra creamy texture.
  • Swap out the egg noodles for gluten-free pasta or elbow macaroni.
  • Completely omit the cheese or use a dairy-free option. Keep in mind it will be less creamy, but just as tasty!
  • Transfer cooked casserole to a casserole dish and sprinkle with panko or regular bread crumbs. Broil 6-8 inches from the heat for 2-4 minutes until brown. This will add a nice crunchy texture.

How to store it

This casserole will keep in an airtight container in the fridge for up to 3 days or in the freezer for up to 2 months.

Are there other vegetables I can add?

Absolutely! Diced baby carrots work well, as do sliced mushrooms (which are complemented by the cream of mushroom soup!). For convenience, you can also use frozen mixed veggies.

Notes

Carefully add the ingredients. Layering the ingredients helps in avoid getting a burn message on the Instant Pot due to the pasta soaking up the liquid too quickly
Solid white albacore tuna is preferred for this recipe since it has a milder tuna flavor. Or choose tuna in water over in oil.
Use regular milk or other milk of choice (if dairy free). If you don’t mind the extra calories, use half and half for an extra creaminess.
Use elbow macaroni in place of egg noodles. Increase cooking time to 4 minutes
Use gluten free pasta if desired and cook for 3 minutes.
Leave out the cheese or substitute dairy free cheese if desired
If you would like a crunchy topping, transfer the cooked tuna casserole to a casserole dish and add ½ cup of panko or regular breadcrumbs and broil about 6-8 inches from heat for a 2-4 minutes until brown. (Careful not to burn)
Add other vegetables like diced baby carrots and/or sliced mushroom if desired. You can also use frozen mixed vegetables to save even more time.
Store in an airtight container for up to 3 days
Freeze for up to 2 months
