I tried this recipe twice and the 2nd time was better. I used BOTH the cheese (a 2% milk fat Mexican blend) AND some crushed Lays Kettle chips over the top of the cheese. My whole family loved it and it lasted two nights (4 servings each night). I also used less mushrooms (8 ozs) and no red pepper flakes. This recipe beat my grandmother's back in the days when I could eat gluten!

This recipe is deluxe! I made it for dinner tonight and both my husband (who is not gluten intolerant)and I just loved it! I forgot all about the pepper flakes but it didn't matter. We think it's better than the wheat noodle old favourite we used to make. I'm glad to read in the other reviews that it works well with other ingredients - a whole new world of options has opened up!! Thanks all!

YUM!!! This was the best Tuna Casserole I've ever had. Shocking. This technique was new to me. And I have to say it's very forgiving! I made a ton of small modifications. I didn't have mushrooms so left hem out. Used less creme cheese (ran out), used more peas - finishing up a bag. Used less cheese for the topping (swiss gruyere combo - what I had on hand), added 3 T of spicy mustard, 1 T Worcestershire, 1 t of hot sauce to the milk, tuna liquid. No kids at my house and we like the food really flavorful. If you have kids - don't change a thing.

It was fabulous! I'm going to try this same technique for other casseroles and experiment. I can imagine a stroganoff substituting sour creme for the cream cheese would be great! Thanks for the recipe.
