The Best gluten free tuna casserole recipe

I have to admit, I was a bit skeptical when my husband first introduced me to the idea of a tuna casserole recipe that was gluten-free. I mean, who doesn’t love a good tuna casserole, right? But what really drew me in was the fact that this recipe used gluten-free pasta instead of traditional noodles.

As someone who has had to cut gluten out of my diet for health reasons, it’s not always easy to find recipes that cater to my needs. But this one did, and it’s become a staple in our household ever since. The best part is that it’s so easy to make and requires minimal ingredients, which is perfect for busy weeknights when we’re all scrambling to get dinner on the table.

My kids love helping me assemble the casserole and they always ask for seconds (and sometimes even thirds!) The combination of the flaky tuna with the creamy sauce and crunchy pasta is just perfect. It’s also super versatile – we like to serve it with a side salad or some steamed veggies for a quick and easy meal.

And let’s be real, who doesn’t love leftovers? This recipe makes plenty so we can enjoy it again the next day or freeze it for later. Plus, it’s a great way to get some protein into our diets without having to cook up a whole bunch of meat.

The best part is that this recipe is super adaptable – if you want to make it more substantial, just add some diced veggies or cooked chicken on top! My family loves when I make this dish for special occasions like holidays or birthdays because everyone knows they’ll leave full and satisfied. And let me tell you, this recipe never fails to impress!

In fact, I’ve even started making it for potlucks and gatherings because everyone raves about it whenever I bring it out. It’s become such an integral part of our mealtime routine that I’ve even started experimenting with different flavors by adding in different spices or herbs here and there.

8 oz gluten free elbow macaroni or rotini
2 cans (5 oz each) tuna, drained and flaked
1 cup frozen peas
1/2 cup diced onion
2 tablespoons butter or dairy free alternative
2 tablespoons gluten free all purpose flour
2 cups milk or unsweetened almond milk
1 cup shredded cheddar cheese (or dairy free cheese)
1/2 teaspoon salt
1/4 teaspoon black pepper

👨‍🍳Directions

1Preheat oven to 375°F.
2Bring a large pot of salted water to a rolling boil over high heat.

5Add the diced onion and cook until softened, about 3 to 4 minutes, stirring occasionally.
6Sprinkle in the gluten free flour and whisk continuously for 1 minute until the mixture is bubbly.
7Gradually pour in the milk while whisking constantly to prevent lumps.

10In a large mixing bowl, combine the cooked pasta, flaked tuna, frozen peas, and the prepared cheese sauce.

❓ Frequently Asked Questions About Gluten Free Tuna Casserole

1. Can I use any gluten free pasta for this recipe?

Yes you can use any gluten free pasta shape but I recommend something like elbow macaroni or shells. Those shapes hold the sauce well. Just be sure to cook it al dente because it will continue to cook in the oven. Overcooked gluten free pasta can get mushy.

2. How do I make the sauce creamy without gluten?

I use a gluten free all purpose flour blend to make a roux. You melt butter, whisk in the flour, then add milk slowly. This creates a smooth, thick sauce. You can also use a cornstarch slurry if you prefer but the roux gives a richer flavor.

3. Can I make this casserole dairy free as well?

Yes you can substitute the butter with a dairy free margarine and use unsweetened almond milk or oat milk for the milk. For the cheese topping use a dairy free shredded cheese. The texture will be slightly different but still tasty.

4. How do I store leftovers and reheat them?

Store leftovers in an airtight container in the fridge for up to 3 days. To reheat, place a portion in the microwave for about 1 to 2 minutes. For a crispier topping, reheat in a 350 degree oven for about 10 minutes.

5. Can I add other vegetables to this casserole?

Absolutely. You can add steamed broccoli, chopped carrots, or even diced bell peppers. Just make sure to cook them slightly before adding so they are tender. Frozen vegetables work great too.

6. Is this recipe suitable for freezing?

Yes you can freeze the unbaked casserole. Assemble it in a freezer safe dish, cover tightly, and freeze for up to 3 months. Thaw in the fridge overnight then bake as directed, adding about 10 minutes to the baking time.
