Hey y’all, it’s Anne here from Beyond the Bayou Blog! As someone who’s spent years working in restaurants, I know how tough it can be to find tasty keto-friendly dishes. That’s why I’m excited to share this keto tuna casserole recipe with you today.

Like a lot of you, I’ve struggled with my weight and have tried different diets over the years. The keto diet has really worked for me in keeping my cravings under control and helping me shed some pounds. But it can be hard to stick to with all the tempting carb-filled foods out there!

This tuna casserole is one of my go-to keto meals. It’s hearty, filling, and just so darn good. Best of all, it’s easy to make with ingredients you likely already have in your kitchen. No fancy stuff required! Whether you’re keto or just looking for a yummy, comforting casserole, this recipe is sure to hit the spot.

Is This Tuna Casserole Really Keto-friendly?

You’re probably wondering if this tuna casserole fits the keto bill, right? Well, let me tell you, it absolutely does! Unlike those carb-loaded versions with pasta, canned soup, and even potato chips (seriously, who came up with that?), my recipe is all about keeping it healthy and low-carb.

Here’s the lowdown: the pasta in this casserole has almost ZERO net carbs. How? It’s made with eggs, olive oil, mozzarella, and psyllium husk. Plus, I whipped up the creamy base from scratch, no starchy additives or canned soups in sight.

So, if you’re keeping an eye on your carb intake, rest assured, this dish is totally keto-friendly. Enjoy guilt-free!

Tips For Making Low-carb Tuna Casserole 

  • Crunchy Keto Topping: Craving that satisfying crunch without loading up on carbs? Try scattering crushed pork rinds on top before baking. It’s a keto-friendly move that keeps those net carbs in check while adding that perfect crispy texture.
  • Chicken Swap: Feeling adventurous? Swap out the tuna for some shredded chicken. It’s a tasty twist that brings a whole new dimension to the dish.
  • Almond Milk Alert: When you’re pouring in the milk, make sure it’s unsweetened almond milk. Skip the flavored or sweetened stuff to keep your casserole low-carb and on point.
