Even though I love to whine complain about how hot is still here, I can’t help myself from turning  the oven to bake yummy things. Most people save casseroles for the fall and winter but not me! I think I made this Tuna Noodle Casserole about 3 times during the summer but can you blame me? It’s so easy to whip together during busy nights and it’s so good! So good.

Serving Tuna Noodle Casserole

My hubby is kind of picky when it comes to his Tuna Casserole so to get it just perfect I sauté the onions in butter, add milk & use a big can of cream of mushroom soup to make it creamier – can’t have a dry casserole right?!

    Can tuna casserole really be this good? Was surprised to see this on Muy Delish as it’s very traditional and pretty ordinary so hard to do much with. If you like tuna casserole you will love this. If you aren’t a tuna casserole fan you may become one after trying this!

  2. Hi Ana! I can’t wait to make this dish! Would you know how many calories are in each serving? Thank you! Great website and thanks for sharing 🙂

    1. Hi K! I honestly didn’t keep track of the calories in this recipe since I know they’re not on the low side. Usually when the fat content is a little high I try to make my portions smaller or try to have this dish for my “cheat” meal lol!. Thanks for stopping by! xoxo
