One Pan Orzo with Tuna and Zucchini
This one pan orzo with tuna and zucchini is flavorful and delicious and comes together so fast as everything cooks in one skillet or pan.
This easy, comforting meal makes the most of fresh garden produce, and it can’t be beat for a simple weeknight dinner!

How to Make This One Pan Recipe
Since everything cooks in one skillet or pan, the steps are important for this tuna zucchini recipe!
- Cook the zucchini until it is golden. To get that delicious color (and resulting flavor), let the oil heat until hot and rippling before adding the zucchini, and then let the zucchini cook without stirring for a minute or so. Don’t cook the zucchini too long! You don’t want it mushy. Just slightly softened.
- Remove the zucchini to a plate or dish.
- Toast the orzo and garlic in the pan and then add the broth.
- Cook the orzo, uncovered, at a gentle simmer until the pasta is al dente.
- Stir in the tuna, zucchini, and lemon juice.
- Add the fresh basil and Parmesan cheese.
- Serve immediately! (Why wait? This dish is so delicious!)
Pan Size: use a deep 12-inch skillet for this recipe. If you don’t have a deep skillet, a 6- to 8-quart saucepan or pot will work (the wider the bottom of the pan, the better for cooking the zucchini).
A Few Notes About Ingredients
- Tuna: I use canned, water-packed chunk light tuna for this recipe. You can experiment with other types of canned tuna, although try to avoid oil-packed tuna as it may make the overall dish too greasy.
- Zucchini: yellow zucchini or yellow squash can be subbed for green zucchini. For less noticeable zucchini pieces, try shredding the zucchini. If doing so, it would need just a quick flash in the pan in the first step (or maybe not at all??).
- Orzo: orzo is small rice-shaped pasta. Another type of small pasta, like ditalini or small shells, could probably sub in quite well for the orzo.
- Lemon juice: don’t skip this ingredient! The fresh lemon juice brightens the dish and adds the best flavor. You can sub in half the amount of red wine vinegar for fresh lemon juice, if desired (and add more to taste, if needed).
I feel like canned tuna main dishes get a bad rep. I don’t blame the haters – I cringe thinking of the sludgy tuna noodle casserole of the 80’s (also known as my formative years).
However, recipes like this one pan orzo with tuna and zucchini should revive canned tuna’s reputation forever! It is such a lovely dish.
Unassuming? Sure. Simple? Absolutely. Very, very tasty? 100%
Browning the zucchini until golden and adding fresh basil and punchy Parmesan are just a few of the elements that elevate this humble dish from average to amazing. I’m making this on repeat while I still have zucchini and basil bursting from my garden. I hope you love it!
One Pan Orzo with Tuna and Zucchini
Ingredients
- 2 tablespoons olive oil, divided
- 4 to 5 cups diced zucchini (1/2- to 1-inch pieces)
- Pinch of salt and pepper
- 12 ounces dry orzo pasta (1 3/4 cups)
- 2 cloves garlic
- ⅛ to ¼ teaspoon red pepper flakes
- 3 ¾ cups chicken broth or stock
- ½ teaspoon salt (use 3/4 to 1 teaspoon salt if using low-sodium broth)
- 2 (7-ounces each) cans tuna packed in water, drained (see note)
- 2 tablespoons fresh lemon juice (see note for alternative)
- ½ cup finely shredded Parmesan cheese, plus more for serving
- ½ cup torn fresh basil leaves
Instructions
- In a deep 12-inch skillet or pot, heat 1 tablespoon of the olive oil over medium heat until rippling and hot. Add the zucchini and sprinkle lightly with salt and pepper. Cook, without stirring, for a minute or so. Stir or flip, and continue cooking for 2 to 3 minutes until the zucchini is tender but not mushy.
- Remove the zucchini to a plate and return the pan to medium heat.
- Add the remaining tablespoon olive oil and stir in the orzo, garlic and red pepper flakes. Stir constantly for 30-45 seconds until the mixture smells fragrant.
- Stir in the broth and salt and bring the mixture to a gentle simmer. Continue simmering, stirring often, until the orzo is tender, 8 to 9 minutes. Moderate the heat as needed, while cooking, to prevent the orzo from sticking on the bottom of the pan. Don't boil too vigorously or the liquid will evaporate faster than the orzo cooks. Add additional broth a little at a time, if needed. It's ok (and preferred) for there to be a bit of broth left after the orzo is cooked so that the overall dish won't be dry.
- Add the tuna, zucchini, and lemon juice. Stir and cook until heated through.
- Stir in the Parmesan cheese and basil. Season to taste with additional salt and pepper, if needed (important!). Serve immediately with additional Parmesan cheese, if desired.

I was not sure if my teenage boys would like this dish. I used the Goodles curveball noodles because I didn’t have orzo, and we enjoyed every bite. Thank you for getting us to step out of the box with our lunches. It was a healthy and fast option that will be a repeat.
I love this so much I have made it twice in the last week.
I’m so happy to hear that, Deanna!!
Waaaaa I’ve had a terrible time with zucchini the last few years. I’m determined next year to keep the vine borers away!! I want to be drowning in zucchini!
I hear you, Monica! The last two years, I’ve lost all my zucchini plants to squash bugs. This year I was fully expecting the same…but shockingly, it didn’t happen. I have literally zero idea why it’s been different this year, but I’m sure next year will be depressing so I guess I’ll be grateful. Those bugs are so annoying!
We have also had a problem with vine borers and started spraying our ground with Bt (Bacillus thuringiensis) during the dormant season and spraying our squash plants. It kills the eggs in the ground and the bugs that may try to burrow in the vine.
So good! The lemon, garlic, and pepper flakes are perfect accents. I used 3 cans of tuna to help satisfy my teenage son, but even without that extra, it made plenty more than I expected. Will definitely add to the recipe book!
Thanks for the review, Vicky!
I made this today and it was so so good! I was intrigued when you posted it but did not expect to like it as much as I did. Will definitely be making this again, for sure worlds better than the mushy tuna casseroles of our childhood!
I’m glad you enjoyed this, Kiersten! And I agree…tuna “casseroles” have come a long way since the 90’s. 🙂
To be totally honest, I was a bit skeptical of this recipe. But I thought to myself “just trust Mel! Shes never let you down before.” So I made it for dinner thinking that only my husband and I would eat it. My entire family loved it! Including my three year-old, whose diet mainly consists of string cheese and gogurts. Most of my family didn’t even realize that it was tuna until I told them. Haha I love the combination of all the flavors! I will be making this again!
I appreciate the honest review, Natalie! Phew! Relieved! Haha. Glad everyone enjoyed this!
This one was a hit with my husband. He loved it. Needed a quick dinner and wanted to use some of my zucchini. I did however, sub chicken breast for the tuna. I diced it up, sauteed it prior to cooking the zucchini, removed it from the pan and added it back in with the squash. My husband is not a tuna lover. It was delicious!
Thanks for the details on using chicken in place of tuna, Lynette! Glad this was a hit!
Fast, easy and delicious. I liked the hint of heat the red pepper flakes added. I had no idea what to cook for dinner and this saved me!
Thanks, Aubrey!!
Mel did it again, another recipe to add to my collection. I made this recipe tonight and very happy I did. The mixute of red pepper, lemon, basil, parmesan cheese has a pleasing taste with the tuna. I did not have orzo pasta, used rotini. Was very easy to make as well; will be making it again.
Thanks so much for making this so fast, Sharie – and taking the time to report back! Glad you loved it!
Do you know if this can be made with quinoa or rice? My husband can’t eat wheat or most grains so I’m always looking for alternates in your yummy recipes!
Good question, Heidi – I think it could work quite well with either. For both rice and quinoa, I’d recommend covering the pan while it cooks vs letting it simmer uncovered as the recipe states to do with the orzo pasta. You might need to play around with grain to liquid amounts to get it just right. Good luck if you try it!
Mel – oh no, hoping your son recovers quickly. No fun. You’re a great mom. He is so lucky to have you.
You are so sweet, Teresa. Thank you! He’s doing ok. Been kind of a long weekend, but every day is a bit better.
