Close up of Tuna Noodle Casserole

Growing up, if you wold have told me that I would be talking about the best tuna noodle casserole, I would have thought you had gone mad. I don’t know, I think I had reservations about tuna and then canned tuna. But oh how the times have changed. Give me all the tuna cuz I love it!

Okay, so to address the elephant in the room…. quarantine.

Honestly, this Southwestern Tuna Casserole is such a good option while we are on lock down. A lot of the ingredients are shelf stable. So go ahead, open up your cabinet door, and wave hello to your bulk of 40 plus canned tuna you have sitting there……. And just to think, your initial intention was that you and your family would be eating close to 70 canned tuna salad sammies. MWHAHAHAHAHA.

Don’t worry Boo Boo’s I got you

Canned tuna never looked so nice. The reason I deem this the best Tuna Noodle Casserole, is because it has a nice personal twist. Yes, I put a spicy kick to make this not your average tuna casserole, but a Southwestern Tuna Casserole. And holy moley, did it not disappoint. Every bite is a creamy, zesty surprise!

You can really use any type of noodles for this casserole. Just be sure to follow the instructions on the box. I used my pasta obsession, Banza. Per serving, Banza pasta has 14 grams of protein in a 2 oz in comparison, of the 2 grams of protein in traditional pasta. I know, I know I’ve talked about this pasta before- but it’s just my fav! Life hack, if it’s your fav too , you can order bulk orders of 6 either on a monthly or bi-monthly subscription through Amazon. Subscribing saves you money and you’ll always be stocked. You’re Welcome. And no, I’m not an affiliate- Just passionate.
