Ingredients for Tuna Spaghetti with Canned Tomatoes
- 2 tablespoons olive oil

- ¼ teaspoon red pepper flakes
- 28 ounces canned whole peeled tomatoes
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- 10 ounces canned tuna (2 cans)
- 8 ounces dried spaghetti (or pasta of your choice)
- ¼ cup chopped flat-leaf parsley (optional, for garnish)
How to Make Tuna Pasta with Canned Tuna
Boil Pasta: Bring a large pot of salted water to a boil. Cook pasta according to package directions. Drain and set aside.
Make a Garlic-Infused Tomato Sauce: Heat olive oil in a large skillet or braising pan over medium. Add minced garlic and red pepper flakes, stirring constantly for about 1 minute.
Break Down the Tomatoes: Pour in the canned whole peeled tomatoes and use a wooden spoon or fork to gently break them apart. Lower the heat, if needed, to avoid splattering.
Simmer the Sauce: Season with kosher salt and black pepper. Simmer the sauce gently for 5 to 7 minutes, until slightly reduced.
Add the Canned Tuna Fish: Stir in the canned tuna (including the liquid), breaking it up into chunks and mixing thoroughly with the tomato sauce. Simmer for another 3 minutes to allow the flavors to meld.
Combine and Serve: Add the cooked pasta directly to the skillet. Toss until well-combined and heated through. Garnish with chopped parsley, if desired, and serve hot.
Recipe Tips: How to Cook with Canned Tuna
- Use quality canned tuna. I recommend Safe Catch Wild Ahi Yellowfin Tuna, which is Whole30 Approved and delivers 43 grams of protein per 5-ounce can.
- Break tomatoes easily: Crush whole tomatoes by hand before adding to the pan for faster sauce prep.
- Stir often to avoid burning and help the sauce coat the pasta evenly.
Variations and Substitutions for Tuna Spaghetti
- Tomatoes: Use diced canned tomatoes for a chunkier texture and faster cook time.
- Pasta: Swap spaghetti for linguine, bucatini, fettuccine or gluten-free pasta for a variation that suits your dietary needs.
- Add-ins: A handful of capers or sliced olives can add a briny twist to the tomato tuna pasta.
Let leftovers cool to room temperature before storing. Store in an airtight container in the fridge for up to 3 days. This pasta with canned tuna tastes delicious served cold, making it a great choice for packed lunches or meal prep.
