Overview: How To Make Keto Tuna Casserole Recipe?
Get ready to indulge in a childhood classic with a keto twist – it’s time for Quick Keto Tuna Casserole, a revamped version of Mom’s Tuna Bake. With just 15 minutes of prep time and 30 minutes in the oven, you’ll have a satisfying entree ready to serve.
To kick things off, preheat your oven to 350 degrees. While it’s heating up, grab a 9″ x 9″ or 9″ x 11″ oven-proof pan or a small casserole bowl, and give it a quick spritz with avocado oil to prevent sticking.
Now, let’s talk ingredients. You’ll need two cans of Albacore Tuna (5.5 oz each), along with chopped baby carrots, celery, onion, and frozen petite peas. Don’t forget the flavor boosters: lemon pepper seasoning and shredded Colby jack or cheddar cheese. For the creamy binder, mix together an egg, mayonnaise, and sour cream in a medium bowl, then toss in the tuna and veggies.
Once everything’s nicely combined, pour the mixture into your prepared pan and sprinkle the remaining cheese on top. Pop it in the oven and let it bake for about 30 minutes, until the cheese is melted and the casserole is hot and bubbly.
When it’s done, cut it into four servings and dig in while it’s still warm. It’s a hearty, keto-friendly meal that’ll satisfy your cravings without derailing your low-carb lifestyle. Enjoy!

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.
What To Serve With Tuna Casserole?
Variations You Must Try!
- Switch up the Tuna: Instead of the regular tuna in water, go for tuna in olive oil. Trust me, it adds a whole new level of yum!
- Swap the Sauce: Don’t feel like mayo? No problem! Give sour cream a shot instead. Both are great, but hey, I’m team mayo all the way!
- Add Some Dill: Want to kick up the flavor? Throw in some dill! It’s like a little burst of freshness in every bite.
- Cheese Choices: Out of Gruyere? No sweat! Reach for sharp cheddar or provolone instead. And if you’re feeling adventurous, smoked gouda is a winner too!
Can You Freeze This Casserole?
Yes. Once completely cool, you can wrap the baking dish in plastic wrap followed by a layer of foil. Freeze it for up to three months. Thaw it in the fridge.
Why Is My Casserole Dry?
This casserole can become dry if the ratio of tuna to creamy ingredients (mayonnaise and mustard) is too high.
I find that ⅓ cup of mayo works well, but depending on the brand of tuna you use, you might need to increase it and use up to ½ cup.
