Tuna Pasta Recipe Ingredients

Spaghetti: A great pasta choice here for the base of the dish.

Salt and black pepper: Added for enhanced flavor.

Extra virgin olive oil: Essential for a rich coating and added moisture for the pasta.

Green onions: Used to build up the background flavor of the dish.

Sun dried tomatoes: Added for a zesty pop of bright flavor.

Capers: These add salty, briny flavor that pairs super well with the flavor of tuna.

Garlic: Included for some traditional Italian flavor.

Red pepper flakes: You can adjust the amount of these added to taste as they are spicy.

Canned tuna in olive oil: Be sure to use tuna in oil vs. tuna in water, as you’ll also be including the oil from the can for the pasta dressing.

Lemon: A key flavor here to enhance the tuna. Both the zest and juice will be used.

Parsley: This ingredient adds fresh herby flavor and a pretty pop of color.
