Ingredients
  

  • 3 large cans tuna drained (about 15 oz total)
  • 1 onion finely chopped
  • 1 large carrot or 2 small, diced
  • 2 tablespoons olive oil
  • 2 cups canned crushed tomatoes
  • ½ teaspoon dried basil
  • 1 teaspoon sugar
  • Salt to taste
  • Black pepper to taste
  • 10 oz spaghetti

Instructions
 

  • Prep the veggies. Finely chop the onion and dice the carrot into small cubes.
  • Sauté the onion. Heat olive oil in a deep skillet over medium heat. Add the onion, sprinkle with a pinch of salt, and stir occasionally for 5 minutes until soft.
  • Cook the carrot. Add the diced carrot to the skillet. If the veggies start to stick or burn, add about ¼ cup water (not too much—don’t let them swim!). Cook for 15 minutes, adding small splashes of water as needed, until the carrot is soft.
  • Cook the pasta. Meanwhile, boil the spaghetti in a pot of salted water according to package instructions. Drain and set aside.
  • Make the sauce. Pour in the crushed tomatoes, dried basil, sugar, salt, and pepper. Bring to a boil, then simmer for 2 minutes to let the flavors meld.
  • Add the tuna. Stir in the drained tuna, turn off the heat, and mix well. Taste and adjust seasoning if needed.
  • Serve. Spoon the sauce over the cooked spaghetti and enjoy!

Notes

Use good-quality canned tuna for the best flavor—tuna in olive oil adds extra richness.
If the sauce thickens too much, add a splash of pasta water to loosen it up.
