Paleo Tuna Casserole with Butternut Squash Pappardelle

veggie filled (3)

Oh my gosh. This casserole was out of this world. You should probably stop what you’re doing and start making noodles out of that butternut squash that has been sitting on your counter for two weeks. This tastes like an honest-to-goodness midwest tuna noodle casserole-without making you feel like you have a rock in your stomach after you eat it. It is so filling, but not at all heavy! Loaded with beautiful veggies and all kinds of good-for-you ingredients, this is definitely going to be a staple at our house. Not to mention that it’s a dream for fall days when all you want is something warm and comforting.

My teeny tiny helper and I danced to the Dinosaur Stomp while I made the squash noodles. Well, I danced and she pounded her high chair tray with a St. Joseph block and a rattle. I was prepared for it to be difficult to make noodles from a raw winter squash, but the butternut quash was softer than I expected and we made quick work of it. Pappardelle is a wide noodle, like an extra large fettuccini. You could also cut the squash into large lengthwise chunks and spiralize it, but these big noodles are like beautiful Autumn confetti. Here’s what the squash looked like all noodle-ified.

I left the squash whole and used a Y peeler to shave little ribbons around it until I had reached the seeds, then continued around the top part of the squash until I had almost the whole thing in noodle form. While I made the squash noodles, I sautéed the onion, mushroom, and kale in a skillet. I added the cans of tuna and all other remaining ingredients to a mixing bowl and stirred in the sautéed veggies, then mixed it all in with the squash noodles and baked it. I didn’t want the squash to be mushy, so I took it out when the noodles still had the tiniest bit of crunch, but that is a matter of preference. Let me know if  you make this and what you think!

  1. Oh yum! That looks amazing. I actually just took our only butternut squash and threw it in the slow cooker for a soup, so I think I’ll need to run by the store sometime for more squash to make this.
