Incredible Low Carb Tuna Pie Recipe

Here is a recipe for an incredible low-carb tuna pie recipe made with cheese, green beans, and low-carb flour. Creamy and filling, this tuna fish pie makes a great dinner dish!

Canned tuna is one of the most affordable protein options on the keto diet. Even if you don't think you are a huge fan of canned tuna, you'll love this pie. The filling and crust totally improve the tuna taste.

This recipe reminds me of my favorite tuna pot pie recipe. I changed it up and gave it a crumby topping instead of a traditional pie crust. It's both gluten-free and low in carbs. Plus, it's just so wonderful to be able to enjoy a pot pie on a low-carb diet.

And, not to mention, it's both super-easy to make and it's budget-friendly too!

For anyone that is looking for delicious and different fish recipes to make during Lent, save this one! It's basically comfort food on a keto diet - it's that good.

Ingredients Needed For Tuna Pot Pie

If you have ever baked keto-friendly recipes before, you probably already have everything you need to make this dish. If not, they are easy to find at the store.

Low-Carb Flours

You can either use Carbquik (or almond flour) and then add in some coconut flour. When you use both almond and coconut flour together, you will create the perfect texture for the pie crust.

Dairy Products

The creamy sauce is made with lots of dairy. I used a combination of cheddar cheese, butter, and sour cream. The sour cream gives it a fantastic tartness and keeps it from tasting too rich.

Spices

This is where you can really customize how your tuna pie tastes. The only spices I used are salt and paprika. If you want it to have a bolder taste, sprinkle in some garlic powder.

Tuna

It's really easy to use canned tuna in this recipe! If you prefer fresh tuna, then cook some up and use that instead. This recipe is pretty flexible, and either option will work.

Eggs

The eggs bind all the sauce ingredients together and help them bake up in a thicker and richer way.

Mayonnaise

Mayo is a regular part of traditional tuna casserole. I've heard of people replacing it with plain Greek yogurt. If you do, it will alter the flavor slightly and change how many carbs this recipe has.

Vegetables

I used green beans for the veggies. Either canned, fresh, or frozen will all work perfectly in this recipe.

For the onion, save time and use minced dry onion or even frozen diced onion. Of course, fresh onion will work too, but it just takes longer to cut up.

Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.

Quick Tips:

• If you want the crumb topping to be even crispier, sprinkle some shredded parmesan cheese on top during the last 5 minutes of baking.
• Try this recipe with canned chicken! It will still taste just as delicious.
• They might have a few more carbs, but replace the green beans with peas to change up the texture and taste.
• Let the hot tuna pie sit for several minutes before slicing. This helps the slices hold together better as well.

How To Make A Low Carb Tuna Pie

All of the exact steps are listed in the printable recipe card at the bottom of this post. First, here are some photos and extra tips for each part of the process.

Make The Low-Carb Pie Crust

To start, you'll combine the flours, one cup of cheese, salt, and paprika in a medium bowl. Then, cut the butter in using a pastry blender.

Reserve one cup of the pastry mixture. You will use this as the topping for the pie later. Press the remaining dough into a pie pan.

Add Tuna And Veggies

Place the tuna and green beans into your pie crust.

Make The Cream Sauce

In another bowl, mix the eggs until light and fluffy. Then, mix in the sour cream, the remaining cheese, mayonnaise, and onion. Pour this mixture over the tuna and green beans.

Add The Pie Crust To The Top

Finally, sprinkle the reserved pastry mixture over the top of your pie. Bake it until the top is browned and the pie has risen.

What To Serve With Keto Tuna Pot Pie

This is pretty much an entire meal in one dish! You have protein and veggies in a rich and creamy sauce. To round this out and make it feel like a filling main course, start out with your favorite salad.

This baby kale and avocado salad has parmesan cheese and is light enough to compliment this seafood pie.

Want something sweeter to offset the savory? Make a spinach strawberry salad with a tangy vinaigrette. You can't go wrong with spinach and strawberries.

Is Carbquik gluten-free?

No, it is not gluten-free. If you need a gluten-free option, I suggest replacing it 1:1 with almond flour.

How do you store tuna pie leftovers?

Store leftovers in the refrigerator in an airtight container. Alternatively, you can wrap the pie plate tightly with plastic wrap before refrigerating. It won't last too long, so try to eat it within 2-3 days.

I'm a huge fan of tuna! In fact, I have two delicious tuna casserole recipes you should try. My low-carb tuna casserole has spinach in it, so it's a fantastic source of iron.

If you like mushrooms, then make shirataki tuna noodle casserole. It's creamy and has a deep flavor that you'll really enjoy.

Yes, you can! In fact, it is really easy. Just sprinkle as much red pepper flakes as you want into the sauce. You can also try adding some sliced jalapeno peppers into the recipe as well.

Is canned tuna safe to eat?

If you are worried about tuna being contaminated from radiation from Fukushima, you can read more about that in this article. Personally, I think those not using responsible fishing methods are more of an issue.

This tuna dish was also very delicious reheated in the microwave. I hope that you enjoy it as much as we do!
