This casserole is easily made with just a few steps. It's so rich and creamy, and totally kid-approved!
We love casseroles in our household! But I seriously contemplated whether or not to post a casserole recipe on our site. I typically love to use all fresh ingredients and make pretty much everything from scratch. But you can't really fancy up a casserole too much or you miss the actual point. So don't get used to it, but I'm actually using some cans of soup for this Instant Pot tuna casserole. It's just the only way to do it! And you could even take this a step further and add something crunchy on top of each serving... Mmmm.
And this is the AMAZING result…
- If starchy bubbles try to escape when you release the pressure, simply close the vent and try again in 30 seconds. Every now and then, depending on the type of pasta, the produce lots of starch. Just release the pressure in increments.
- The pot-in-pot method is necessary to reduce the risk of a burn notice. Our original recipe was written without the pot-in-pot method. However, several readers reported burn notices, so we after testing and development, we rewrote the recipe to insure a delicious casserole with no burn notices!
- The rule for cooking pasta in the Instant Pot is this… Divide the time on box in half, then subtract 2 more minutes. So if it says 8 minutes, you’d do 8 divided by 2 (which is 4) minus 2 — a total of 2 minutes with quick-pressure release. If you plan to substitute a different kind of pasta for this dish, adjust the cook time accordingly.
