  • ON THE TABLE IN 30 MINUTES! – No, really! You need less than 10 minutes prep/hands-on time, and then it cooks in the Ninja Speedi for about 20 minutes. This is a perfect recipe for busy weeknight dinners or lazy weekend meals. Super-fast, super-simple, and delicious!
  • LOW CARB – I’ve kept the carbs low by using less pasta and adding more veggies. You could trim even more carbs off by using a lower carb pasta.
  • INEXPENSIVE – I used organic vegetables and albacore tuna in this recipe, and it came to just under $5 per serving. But you could use less expensive ingredients and save at least $1 per serving!

Tools you’ll need to make Tuna Feta Pasta Bake

I developed this recipe specifically for the Ninja Speedi, but you could make it on the stove and in the oven if you don’t have a Speedi.

Ingredient Substitutions for Tuna Feta Pasta Bake

Penne pasta, Italian seasoning, cherry tomatoes, flaked tuna, sliced Kalamata olives, feta cheese, olive oil, and chopped red onions in white dishes on a white marble counter

Penne or spiral pasta My favorite pasta is penne so that’s what I used in my recipe, but you can use your favorite. I also kept the amount to just six ounces to keep the carb count low. But if you aren’t counting carbs, then feel free to use a full 12 oz box. Just add another cup of water to the cooking pot.

Cherry tomatoes I loooove San Marzano cherry tomatoes from Trader Joe’s, and that’s what I used in my recipe. (That’s why they look long and weird!) But any cherry tomato can be used in the recipe. Try the multi-colored ones that are super-sweet. They’re so delicious!

Feta cheese A block of feta is preferred, but if you can’t find one, you could use crumbled feta. It’s usually a bit drier than a block and it may start to brown much faster during the air frying mode. Be sure to check the amount in the container if you use crumbled. They are often a couple ounces less than a block.

Kalamata olives I prefer the taste of kalamata olives in this recipe over black olives, but black olives would work great, too. And if you’re feeling brave, try green olives!

See the recipe card below for the full list of ingredients.

How to Make Tuna Feta Pasta Bake in the Ninja Speedi

Hands down, this was one of the easiest, fastest, and tastiest recipes I’ve made. Triple win! Here’s how to make it:

Dump the pasta, tuna, and water into the Ninja Speedi cooking pot and stir to break up the tuna.

Put the crisping tray in the upper position in the cooking pot. Add the feta, tomatoes, olives, and onions to the tray. Drizzle with oil and sprinkle with some of the seasonings. Cook according to the settings in the recipe card.

Handy tip: Perfectly Roasted Feta & Veggies!

If you are using really small tomatoes or your onions are chopped really small, you can check on the “doneness” of the veggies and feta before the Speedi shuts off. Just lift the lid when there are still a couple minutes left on the timer. If you like the doneness, then go ahead and remove them. I like my feta really roasted so I make sure that the veggies are chopped fairly big, and I only use large cherry tomatoes so they don’t get too shriveled. That way they are done at the same time the feta is.

When the unit shuts off, lift the lid. Using silicone-tipped tongs to carefully lift the crisping tray out. Dump the veggies and feta into the cooking pot.

I try to move the veggies and pasta to the sides then stir the feta into any remaining water left in the pot.

I then add more seasonings and any extras, like the capers you see in the image above. Stir everything together, but be gentle so the tomatoes don’t burst. Then serve!

FAQs about Tuna Feta Pasta in the Ninja Speedi

Simply substitute gluten-free pasta in the recipe! Also be sure to check the package of feta cheese to make sure there are no starch-based ingredients listed.

You could just leave out the tuna and it would be a vegetarian dish. You could also substitute your favorite meat replacement for the tuna. It would be really delicious with vegetarian Italian meatballs! Or try chik’n or a sausage alternative.

In my opinion, I don’t think a dairy-free feta alternative would taste very good in this recipe, but give it a try if you like. Or you could just leave out the feta and the recipe is still delicious, just not cheesy and creamy.
