    This was surprisingly good! I didn’t expect tuna could taste this nice in a casserole. Will make again!

    I just don’t get it. Is tuna supposed to go with all these veggies? Seems weird.

    1. 5 stars
      I thought the same thing at first! But tuna is super versatile and it actually works really well with the veggies! You gotta try it, it’s delicious!

      I dunno, it seems a bit odd to me too. Like, why so many veggies? Can’t just have the tuna on its own? But hey, whatever floats your boat!

    Super easy to make! The only thing I changed was adding some spices from my garden. Delicious!

    My kids loved this! They even asked for seconds which is rare. Good job!

      That’s awesome to hear! Kids can be so picky. I think the cheese really helps with that!

      Really? My kids wouldn’t touch tuna unless it’s in a sandwich. You must have some magical recipe!

    Tasty! But I added some extra spices to give it a kick. Also used regular mustard instead of Dijon.

    I accidently put too much mayo. It was kind of runny. Still tasted fine, tho.

    Amazing!! Wow! I even brought it to my potluck and everyone loved it!

    Too many ingredients, why the yogurt? Just call it tuna casserole and be done!

      I think the yogurt adds creaminess and balance! Casseroles can be fun with some twists. 😊

      Why yogurt? Seems unnecessary. Just stick to the basics! Tuna casserole is simple!

    Tuna? Gross! Who even likes that stuff? Sorry, but no!

    Can I just use tuna in oil? I ain’t got time for draining cans and all that.

  11. I was so looking forward to this recipe. It needs tweaking. The veggies need to be saute Al dented. The sauce mixture needs to be doubled otherwise it’s too dry. I don’t think this was tested before posting this recipe.

    It’s good but took too long to bake. Next time, I’m gonna precook the veggies.

  13. 2 stars
    How does this even work? Like, are you supposed to eat it hot or cold? Need a response ASAP.

    YUCK! Can’t believe you put tuna in a casserole. That’s just wrong! 😠

    I dunno, it was just okay. The flavor was a bit too strong for me. Maybe I used too much dill?

    1. User avatar damon.oreilly93 says:

      4 stars
      I totally get that! Dill can be pretty overpowering if you use too much. Maybe just try a little less next time. It’s a great recipe otherwise!

    2. 3 stars
      Strong flavors are not for everyone. Maybe add some more veggies to balance it out. I love this casserole, but it takes some tweaking sometimes.

  16. 5 stars
    This was super easy to make! My kids loved it. Will definitely cook again!

    Made this last night, and it was bomb! My husband is picky, and he cleaned his plate!

    1. User avatar Majin Buu says:

      So glad to hear that! My husband is picky too, and he loved it when I made it. It’s such a hit!

    2. User avatar Ka'o Makagh says:

      Wait, did you really say your husband cleaned his plate? Is he usually such a fussy eater? I’m skeptical.

    Way better than I tho’t it would be! Will try with chicken next time instead of tuna. Thanks for the recipe!
