Low Carb Tuna Casserole – This is my low carb, gluten free take on a traditional classic. You won’t even miss the pasta.
Tuna casserole is always reminiscent of my childhood dinner table. Quick and easy. The poor mans friend. Back then it only took a box of pasta, a couple cans of tuna, some condensed cream of mushroom soup, and peas. Now, I am giving it an elevated low carb, gourmet face lift. The dill and the mustard powder really bring this sauce to life. Serving it over cabbage was just a no brainer. Cabbage is a favorite among low carbers and makes an excellent substitution for noodles. It is filling, inexpensive and versatile. That is a winning combination. If you are a fan of cabbage recipes, check out some of my other variations. Fried Cabbage with Kielbasa, Oven Roasted Cabbage Wedges, and Paleo Cabbage Roll Soup just to name a few. What are some of your favorite ways to eat cabbage?

Pin RecipeIngredients
- 2 tbsp olive oil
- 2 tbsp grass-fed butter
- medium head green cabbage (about 1 1/2 lbs), cut into large shreds
- 1 cup onion, chopped
- 3 ribs celery, chopped
- 2 cloves garlic, minced
- sea salt and black pepper, to taste
- 2 tsp dried dill or 2 tbsp fresh dill
- 2 tsp dry mustard powder (get it here)
- 2 tbsp lemon zest
- juice of 1 lemon
- 1 1/2 cup heavy cream
- 1 1/4 cup Parmesan cheese, grated, divided
- 3 – 5oz cans albacore tuna, drained (I use this brand)
- 1/2 cup frozen peas
Instructions
- Heat the olive oil and butter in an extra large ovenproof skillet over medium heat.
- Once heated, add the cabbage, onion, celery, garlic, sea salt and black pepper to the pan.
- Sauté until the vegetables are crisp tender – about 10 minutes.
- Mix in the dill, mustard powder, lemon zest, and lemon juice.
- Pour the heavy cream and 1 cup Parmesan cheese into the pan. Mix in and keep stirring until the cheese has melted and combined with the heavy cream.
- Reduce heat to medium low and let simmer to allow the sauce to thicken.
- Once the sauce has started to thicken, stir in the tuna and the peas.
- Sprinkle the remaining Parmesan over the top of the dish and transfer to the oven.
- Broil on high for 3-5 minutes or until the Parmesan on top has made a golden brown crust.

Love, love, love your Fried Cabbage with Kielbasa recipe. It’s so good!: ) Can’t wait to try this. Was always a fan of Mac n Cheese casseroles with tuna. This sounds like a much tastier and healthier alternative 🙂
Kim (Buffalo / Niagara Falls, NY area) says
Made this last night for dinner. It was yummy and a nice warm comfort meal reminiscent of the old classic. I am sad there were no leftovers for today’s lunch! Thank you for a great easy recipe. I prepped my cabbage noodles earlier in the week and used them for spaghetti and meatballs and then I packed up the rest of the cabbage noodles in the fridge to use for this. Will definitely make again. For those that don’t like tuna, I think it would be delicious with chicken too. And next time instead of the parm cheese browned on the top, I think I might try some crushed pork rinds.
Carol Jenkins says
Since my tuna noodle casserole calls for cream of mushroom soup, I just HAD to add mushrooms. I pureed them into the heavy cream. I really like this recipe…my husband did not, but, then, he does not care for tuna noodle casserole either!
Alison says
Made this, so delicious! I used gruyere. My only question, my cream didn’t think as much as I hoped for, but otherwise, love it and making this again and again!
Peace Love and Low Carb says
You can always simmer it a little longer or add a little more cheese to the sauce to help thicken it. So happy you enjoyed it!
Kim says
This was so yummy! A gourmet version of my childhood memory. My husband and noodle loving 16 year old kept adding more and more to their plates. There was only a smidge leftover which I gladly ate with lunch the next day. Thanks for the great recipe!
Lisa says
Do you think you can use almond cream or coconut cream?
Peace Love and Low Carb says
Yes, the sauce just won’t be as thick. You may want to add a little xanthan gum to help thicken it.

how long does this keep? i made this a few days ago but i dont want it to go to waste and i also dont want to get sick. My husband wont eat it and neither will my son.. i dont know why its freakin delicious.
Peace Love and Low Carb says
If you are worried about it spoiling, you can always freeze it to reheat later.

I’m so excited to see this. I miss tuna casserole enormously!
Laurie Ebarb says
I just made this. Yumm!! I tried to keep to your recipe but I used broccoli instead of peas, added more cheese and put all of it in instead of topping it off and broiling it. I try not to turn on the oven in the summer here in Houston! It tastes great, but mine is mushier than what your photo looks like. My cabbage probably cooked too long while I was getting the remaining ingredients prepared.
Oh also, I couldn’t find “Lemon Zest” so I used Lemon extract instead. Is it similar?
Peace Love and Low Carb says
Lemon zest is just the rind of the lemon peeled off with a zesting tool.
Rachel says
I LOVED this! And both husband and stepkid had 2 helpings each! Total success.
Thank you!
Stacy says
Omg, this is so amazingly delicious!! I’ll be honest, I was nervous this would just be all right but not great; a poor excuse for the real thing. Man was I wrong! This is even better than regular noodle based tuna casserole. I love the texture the cabbage adds and the flavors in the sauce are dead on. Thanks for a great recipe!!
Kristi says
This was delicious. I made the sauce separately with the cream and cheese reducing until thickened in a small saucepan. Then I added salt, pepper , dry mustard, dill, lemon zest and lemon juice. I poured this over the sautéed cabbage, onion and garlic and mixed well. Finished the recipe as written.
So good!

This is my go to for comfort food. The only thing I did different is swap out the dill and lemon and used celery seed and Worcestershire sauce. Thank you Kyndra for this fabulous recipe!

Charity says
I haven’t tried this yet but I’m planning on it, I like the idea of adding some sauteed mushrooms to the cream,and ill probably throw in some red pepper flakes for a little heat but I’m also going to use edamame instead of peas to lower the net carbs and sugar as well I think they will will make a great swap but ill let you know! Thanks for the awesome recipe ????
Angie says
Thank you SO much for this recipe!!! I made this for my husband and two daughters (10 and 5)…and it will now be on our normal rotation. I’m brand new to this low-carb deal and it can be pretty intimidating for sure. So thank you for easing us I to it!
Debbie in TX says
Very versatile recipe that allows you to sub out whatever veggie you may have on hand, as well as type of meat. Love it!
Susan says
Going to try this recipe tonight, it looks really good..thanks
Kim says
Loved the recipe but next time I will leave out the dill and lemon.

Cindy says
I was amazed at how good this was! Will definitely make it again. I think this would be good with chicken breast, too, if you don’t like tuna! Just got your book Kraveable Keto and I’m looking forward to making more of your recipes!
Angela Bennett says
Just made this tonight for the first time. It is delicious! My husband loves it – he keeps getting more helpings! He said it tastes like something we would get at a fancy restaurant. I’ve been missing tuna noodle casserole, a staple comfort food from childhood. Thank you for creating this recipe!

I made this last night and I’m counting the minutes until I can dig into the leftovers. To make it more like the tuna noodle my mom would make while I was growing up I substituted the onion for some very small mushrooms and instead of topping with Parmesan I topped it with shredded cheddar cheese and sprinkled some crushed pork rinds on top. I also left out the lemon zest. It turned out amazing and took me right back to my moms kitchen!
