This No Noodle Tuna Casserole recipe is now, officially, my go-to tuna casserole!

I used to make tuna casserole with pasta and tons of cheese. But since I really didn’t want to do the carb/fat combo, I thought I’d try a no-noodle version just to see how it would turn out.

And turn out, it did. It was delicious.

TUNA CASSEROLE WITHOUT NOODLES

Tuna casserole doesn’t need noodles or rice or any other carby addition to be delicious. In fact, it’s quite good without, as you’ll see if you make this.

However, if you are a die-hard noodle fan, feel free to mix in about 2 cups of cooked pasta as it will work well either way. And I know that for some of you, this may be a tad on the dry side. I like it that way. But for those of you who don’t, mixing in a bit more mayo after baking does the trick nicely!

LOW CARB TUNA CASSEROLE

If you are watching your carbs, this dish might be a perfectly delicious fit for your eating plan. At only about 1 net carb per serving, it’s super easy to fill up on this dish without being worried about your carb intake. So enjoy!

What You’ll Need

2 medium garlic cloves – If your cloves are larger, you’ll still want to use 2 cloves. However, if they are smaller, you’ll want 3 or 4 of them.

1 large celery stalk  – You’ll want to chopped this as fine as possible.

½ large red bell pepper – Chop this just a finely as the celery. 

¼ large red onion – Chop this fine as well. The finer you chop, the better the texture of the finished casserole will be.

1 cup green beans – I used frozen/thawed, but fresh works too. These don’t have to be chopped as fine as the celery, pepper and onion, but you still want to chop them on the smaller size.

1 tbsp. olive oil – You can use any oil you prefer. Olive oil is simply what I had on hand.

20 oz. water packed tuna – This was 4 standard cans. Make sure it’s water packed, no oil packed. Drain the water well.

¼ cup mayonnaise – store bought or homemade – see links above

1 cup grated cheddar cheese – It’s best to hand grate from a block of cheddar.

2 tbsp. almond flour – You can use almond meal too, but almond flour will give you a better consistency.

Salt and pepper – I added these to taste after cooking.

In a medium skillet, sauté the onions, garlic, celery, bell peppers and green beans in the olive oil over medium to low heat until the onions are translucent. Allow to cool.

Step four is to mix everything together in a large mixing bowl.

Step five is to sprinkle the almond meal over your casserole and bake.

Sprinkle the almond meal over the top of the casserole and bake at 350 F. for approximately 20-25 minutes (just enough to get the cheese melted.)

Step six is to remove from oven and allow to cool slightly.

Remove from oven and allow to cool slightly before serving. Add salt and pepper to taste.

Step seven is to serve with your favorite sides.

Pairs well with a salad or other veggies.

Mercury In Tuna

Every time I post a recipe that uses tuna, I can count on getting at least one comment admonishing me for “promoting tuna” when it’s such a direct source of mercury.

I get that this is a concern for many people. And if you don’t want to eat tuna, simply don’t eat tuna. I have many other recipes here you’ll enjoy.

  1. Can I use another type of cheese?

    1. The Gracious Pantry says:

      Phyllis – Sure! Whatever sounds good to you! 🙂

  2. I am making this tonight for dinner. I love tuna casserole. I have shied away from them since I am GF AND LF in the last few years. Sounds yummie!

    1. The Gracious Pantry says:

      Jan – Great! Let me know how you like it! 🙂

  3. Tiffany, I made your tuna casserole…Holy Moley, delicious!! I did tweak it a bit. I didn’t have green beans so I added chopped spinach and no almond meal so I topped it with sliced almonds and I added a couple of shakes of Cayenne pepper for a little POP. I added some GF pasta by Tinkyada (my favorite) shells. I also added CABOT LF cheddar cheese (from VT). I will be making this again…thanks! I love tuna casseroles!

    1. The Gracious Pantry says:

      Jan – Fabulous!!! I’m so happy you enjoyed it! 😀

  4. Is there a way to know the nutrition facts? Like calories, fat and so on?

    1. The Gracious Pantry says:

      Vanessa – There are a lot of online calculators where you can easily enter the recipe. I recommend MyFitnessPal.com because all you have to do is copy the recipe page url into the appropriate box and it will import the entire recipe for you. It’s awesome! Hope that helps.

  5. Paula Ann McCabe says:

    What should the oven temperature be?

    1. The Gracious Pantry says:

      Paula – 350 F.

  6. My husband liked this except for the green beans. Hr is not a big veggie person and is very sensitive to texture issues with veggies – somehow he didn’t like the ways the beans were cooked. I could either boil and cook them or possibly just try french style green beans for him.

    1. The Gracious Pantry says:

      Patti – Sorry he didn’t care for them! You could leave them out all together if you prefer.

  7. Tiffany, is there any NON Facebook way to read your Low carb recipes?

  8. Jessica Lynch says:

    Have you ever tried to make this and freeze it? Either before baking or after baking and cooling?

    1. The Gracious Pantry says:

      Jessica – No I haven’t. Technically, you can freeze anything. But I’m not sure what the texture would be like after thawing.

  9. This is AMAZING. I really didn’t think it would be as good without pasta, but somehow this is even better than the classic!

    1. The Gracious Pantry says:

      E – Thank you so much! I’m so happy you loved it!! 😀

  10. This would probably be good scooped into a half of a cooked spaghetti squash too

    1. The Gracious Pantry says:

      A – I hadn’t thought of that, but you might be right! 🙂

  11. I want to try this recipe but just so i am correct..it calls for 4 5oz can tuna, right?

  12. Anne Cooper says:

    This sounds delicious! How many cups or ounces is a serving?

    1. Anne – I never measured. Because it’s in a casserole dish, I just cut it into 8 equal potions. I’ll try to measure next time. Sorry about that!

  13. Terry Row says:

    5 stars
    It sounds great, but everything I make it, I can’t get past Instruction 2. No matter how long I sauté the garlic, celery, bell peppers and green beans in the olive oil over medium to low heat, the onions never turn translucent. They just sit there on the counter. I’ve had to give up several times.
