Using pre-made pesto keeps prep to a minimum while delivering a bright herbal flavor. The recipe is straightforward and flexible, so you can tailor it to what you have on hand or to your family’s tastes.

Why this recipe works

• It’s filling and balanced: canned tuna adds generous protein without extra cooking time.
• Minimal ingredients: the core recipe uses just a few pantry staples for an easy, weeknight-friendly meal.
• Fast to make: with prepared pesto and quick-cooking pasta, the whole dish is ready in about 20 minutes.
• Highly adaptable: add vegetables, cheese, or extra herbs to customize flavor and texture.

Recipe ingredients

Ingredient notes

• Pesto: Store-bought pesto works perfectly and saves time, but homemade pesto also yields excellent flavor.
• Grape tomatoes: Cherry or grape tomatoes work best because they’re small and sweet; if using a larger tomato, remove the seeds and pulp to avoid a watery sauce.
• Tuna: Tuna packed in oil (olive oil preferred) is more flavorful and moist, but tuna packed in water can be used—drain most of the water first and consider adding a little olive oil back in.

Step-by-step

Follow these simple steps to prepare the pasta. Images illustrate the key moments so you can see how the dish should look as you go.

1. Bring a large pot of water to a rolling boil. Salt the water generously—well-seasoned cooking water is the first step to well-seasoned pasta.
2. While the water heats, rinse and halve the grape tomatoes. Set them aside.
3. Cook the pasta according to package directions until al dente. Before draining, reserve about ½ cup of the starchy pasta water to help loosen the sauce if needed.
4. Drain the pasta and return it to the pot. Add the tomatoes, pesto, lemon juice, and the cans of tuna (use the tuna with its oil for maximum flavor; add undrained). Gently fold the ingredients together to combine without breaking up the tuna too much.
5. If the mixture seems thick, stir in the reserved pasta water a little at a time until you reach the desired consistency.
6. Taste and finish with salt, pepper, and more lemon juice to brighten if needed. Serve immediately with optional torn basil or lemon wedges.

Tips and tricks

• Salt the pasta water generously for the best flavor.
• Adjust the amount of pesto to suit your preference—add more for a bolder herbal profile or less if you prefer a lighter coating.
• Mix gently to preserve the texture of the tuna; overmixing will break it into fine flakes.
• This dish is delicious hot, but also works well at room temperature or chilled as a pasta salad.

Additions and substitutions

This recipe adapts easily to what you have on hand. Add or swap ingredients at the final mixing stage.

Add-in ideas

• Garnish with torn fresh basil and extra lemon wedges for brightness.
• Stir in grated Parmesan or shredded mozzarella for a cheesier result.
• Use sun-dried tomatoes or roasted red peppers for concentrated tomato flavor.
• Add extra vegetables like quartered artichoke hearts, steamed broccoli florets, or sautéed onions.
• For more fiber and bulk, add drained, rinsed chickpeas or white beans.
• Sprinkle crushed red pepper flakes for heat, if desired.

Substitution ideas

• Swap canned tuna for canned chicken, salmon, or crab if preferred.
• If fresh tomatoes aren’t available, use sun-dried tomatoes or roasted peppers instead.

Storage and reheating

• Best enjoyed the day it’s made, but leftovers keep in a tightly covered container in the fridge for 3–4 days.
• Pasta can dry out in the refrigerator. Stir in a tablespoon or two of additional pesto or a splash of water before reheating to restore moisture.
• Reheat single servings in the microwave. For larger amounts, warm gently on the stove in a covered shallow pan, stirring occasionally. The dish is also enjoyable cold or at room temperature.
• Frozen: the pasta can be frozen for 2–3 months in an airtight container, but tomatoes may soften after thawing. If concerned, omit tomatoes before freezing and add them fresh after thawing.

Recipe FAQs

What is the best tuna to use for tuna pesto pasta?

Tuna packed in oil—preferably olive oil—adds the best flavor and a moist texture. If available, choose tuna labeled “solid” (solid white albacore or solid light yellowfin) for larger pieces that hold up well in the pasta.

Can I use tuna packed in water?

Yes. Drain most of the water before adding the tuna to the pasta. You can add 2–3 teaspoons of olive oil to the finished dish to replace the flavor and fat that would have come from tuna packed in oil.

What pasta shape is best for pesto?

Short, twisted shapes like fusilli, rotini, gemelli, or cavatappi hold pesto well. If possible, choose bronze-cut pasta for a slightly rough texture that clings to sauce, though any shape you prefer will work.

What pairs well with tuna pesto pasta?

This pasta already provides protein, so light accompaniments work best: a fresh green salad, a bean salad, sautéed vegetables, or a simple cup of vegetable soup are all good options. A simple cheese-and-tomato starter can also complement the meal.
