  1. This is a very forgiving recipe, as I made a few changes (omit dill weed, sub evaporated milk for half and half, sub 2x diced sweet onion for white onion, sub 2x frozen pea & carrot mix for frozen peas) and missed the instruction not to stir before pressure cooking, but it still came out well. This will be my go-to recipe for tuna casserole, as I grew up making upgraded Tuna Helper, not the baked casseroles with crispy topping. This was much better and faster, using only what I had on hand.

    1. Making any adjustments where you feel you can make changes is the best thing about cooking. I am glad you liked this recipe. As for the Stirring instruction, we can add that to the recipe. Thank you for the input.

  2. I am confused. At the end of step 5 it says do not stir. But the first thing step 6 says is stir well. Which is correct?

    1. Hi burt,

      You can stir the ingredients at any point. We just prefer to layer the ingredients and stir it all at the end but either way will work.
