1 cup pesto
Bring a pot of salted water to boil. Add your pasta and cook until al dente, about 10 minutes.
8 oz. pasta
Before draining the pasta, scoop out ¼ cup of pasta water and set aside.
¼ cup pasta water
Drain the pasta and set aside.
While the pasta is cooking, heat a frying pan to medium-high heat with 2 tbs. of olive oil. Add 4 oz. of capers. Sauté until crispy and hot – about 5 minutes. Set aside in a small bowl.
4 oz. capers
Add another tbs. of olive oil to the same frying pan, and set to medium-high heat. Sauté the diced shallots and minced garlic with a little bit of salt and pepper until soft and translucent, about 2-3 minutes.
2 cloves garlic, 1 shallot
Add pesto, pasta water, and lemon juice to the frying pan and combine well until it makes a sauce. Add the tuna, and break it up with a spatula.
¼ cup pasta water, 10 oz. canned tuna, 1 tbsp. lemon juice
Add the pasta and stir until well combined.
Serve, garnished with the fried capers and lemon zest.
Zest of 1 lemon
Notes
Substitutions and Speed Tips
If your pasta doesn’t come in an 8 oz. package, but rather a 1 lb. package, measure 8 oz of dry pasta on a food scale before cooking. Alternatively, if you don't have a food scale, you can separate roughly ½ of the 1 lb. bunch of dry pasta to use for this recipe.
Pasta Substitute: Lentil or chickpea pasta. Spiralized sweet potatoes, zucchini, or carrots. You can also use spaghetti squash.
Pasta Water Substitute: Vegetable or chicken broth, milk, cream, or cornstarch mixture.
Capers Substitute: Chopped green or Kalamata olives, or toasted breadcrumbs.
Olive Oil Substitute: Avocado oil, walnut oil, flaxseed oil, or grapeseed oil. Just note, using these oil substitutes may slightly change the flavor of the pesto pasta.
Garlic Substitute: Garlic powder – substitute at least 1 tsp.
Shallots Substitute: Finely diced yellow or red onions.
Lemon Juice and Zest Substitute: 1 tsp. of vinegar, such as white wine vinegar, red wine vinegar, or apple cider vinegar.
Tuna Substitute: Cod, halibut, shrimp, salmon (canned or fresh), chicken, or chickpeas.
