How to make Tuna Pesto Pasta step by step
Here are some quick visual instructions with a brief explanation. Be sure to read through the full instructions with exact ingredient measurements & steps in the recipe card below!
Step 1: Cook the pasta according to package instructions. Every pasta box has a different cooking time. The key elements to cooking the pasta well is to begin with a large pot of salted water and mix the pasta often to prevent it from sticking to each other.
Step 2: Strain the pasta. It’s important that when you strain the pasta you don’t rinse it. We want the starches of the pasta water to stay on the pasta.
Step 3: Next, add all the Pesto ingredients to a blender or food processor. This includes the basil, spinach, walnuts, garlic, lemon juice, oils, parmesan, and salt.
Step 4: Blend it all together until the basil pesto is super smooth. This usually takes me 2-3 minutes.
Step 5: Time to begin assembling the pasta dish! Start with breaking up the canned tuna chunks in the bottom of a large bowl. This bowl will be used to mix the entire pasta dish together.
Step 6: To the bowl, add the cooked pasta, halved cherry tomatoes, and creamy pesto.
Step 7: Mix it all together until pasta is well coated in the sauce. Taste and add more salt if you like!
Step 8: Time to enjoy the pasta for lunch or dinner! Grab a fork and dig in. What a quick meal!
Recipe tips and tricks
- Use your favorite brand of canned tuna! If you have a preference of type of tuna or a brand that stands out to you, that’s what will work best in this recipe.
- Buy your spinach and basil at most 1-2 days before you make the recipe since they can both wilt quickly and get soggy in the fridge.
- Add some heat to the dish! If you like spicy foods, add ¼ to ½ teaspoon red pepper flakes to the pesto before blending. It will add a nice kick of spice to the recipe.
Storage and reheating
- Storage: This simple tuna pesto pasta stores best in an airtight container in the fridge for up to 4 days.
- Reheating: To reheat the pasta, either microwave a single portion for 1-2 minutes or you can place it in a pot on the stovetop with 1-2 tablespoon water, cover the pot and cook for 8-10 minutes on medium-low (mixing occasionally). This is an easy recipe to meal prep and divide into containers for a few days.
- Freezing: I have not tried freezing this pasta dish, and am not sure I would recommend it. If you give it a go, let me know!
Additions and substitutions
- Swap the spinach: Substitute of either parsley, arugula or even kale.
- Swap the walnuts: Use almonds, pine nuts, or another nut instead of walnuts.
- Swap the parmesan: If you don’t have parmesan (vegan or dairy) on-hand, feel free to leave it out and replace with 1-2 tablespoons nutritional yeast with ½ teaspoon garlic powder and even add 1 teaspoon miso paste.
- Add more veggies: Add peas, sun-dried tomatoes, sautéed zucchini or even artichoke hearts to this dish to add bulk and make it even healthier.
Frequently asked questions
Either way! The pasta can get hard in the fridge if you leave it overnight. So if you want to eat it cold, be sure to prepare it a minimum of 5 hours in advance, refrigerate it, and then serve right away.
Yes! This is actually my personal preference. Some people like to use canned tuna in oil, but I find the water version to be the most ideal ingredient for this recipe.

Instructions
- Fill a large pot with water and 1 tablespoon salt. Add pasta to the pot, stir occasionally and cook pasta according to package directions. Drain the pasta (no need to rinse) through a colander. Set drained pasta aside (it can stay in the colander).
- To make the Pesto, blend all Pesto ingredients in a high-speed blender or food processor until smooth for 2 minutes. If it’s having a hard time blending, pause blending every so often and use a spoon to move things around in the blender and blend again.
- Prepare the tuna by draining the water from the can. Place the tuna into a large mixing bowl and flake it into small pieces using a fork.
- Add the cooked pasta, cherry tomatoes and pesto to the flaked tuna. Mix together until pasta is well coated.
- Taste and adjust salt to your liking if necessary.
- Garnish with lemon zest and grated parmesan before serving.
Test Kitchen Notes
- Reheat: You can microwave a bowl of pasta for 1-2 minutes. Alternatively, reheat on the stove over medium-low heat with a tablespoon or two of water to hydrate it (keeping the pot covered).
- The pasta can get hard in the fridge overnight so I don’t recommend serving it cold the next day. But if you make this recipe 3-5 hours in advance, you can store it in the fridge and then serve it chilled; which is wonderful!
- Swap the walnuts for almonds, pine nuts, pistachios or hazelnuts.
- Swap the spinach for parsley or even arugula.
- Feel free to swap the tuna with canned or freshly cooked flaked salmon too.
