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.
