Cuisine: Italian
Servings: 4


  • 1 pound fettuccine or linguine, spaghetti, etc
  • 3 pints cherry tomatoes halved
  • 1 medium onion diced
  • 1 stick unsalted butter
  • salt and pepper to taste
  • 1/4 cup parsley minced
  • 1/4 cup basil hand torn
  • 2 cups reserved pasta water will most likely not need it all


  • In a large pan saute the onion in butter over medium-low heat until soft (about 5 minutes) then add the tomatoes. Season the tomatoes initially with a teaspoon of kosher salt.
  • Cook the sauce over medium heat for 30-35 minutes (stir frequently and lower heat if scorching) or until the cherry tomatoes have burst and softened and the butter has completely blended in with the tomatoes.
  • Meanwhile, bring a large pot of salted (2 tablespoons kosher salt per gallon of water) water to boil. When the sauce is almost to your liking begin boiling the fettuccine to 1 minute less than al dente.
  • A few minutes before the pasta finishes cooking add 1 cup of pasta water to the sauce and stir to combine. Continue to cook the sauce over medium heat.
  • Add the pasta to the sauce and toss to coat. Cook until the pasta is just al dente then turn off the heat and season to taste with more salt and pepper as required. Add the herbs, toss once more, then plate. If the sauce is at all dry, add more of the reserved pasta water a few ounces at a time to loosen it up. Serve with grated parmesan cheese. Enjoy!



  • Some tomatoes will be juicer than others.  If you need a bit more tomato, feel free to increase the amount of cherry tomatoes or supplement with 14 ounces (half of a can) of crushed plum tomatoes.
  • Make sure to reserve extra pasta water, to thin the sauce as much as required to avoid it drying out. 
  • Leftovers can be saved for up to 3 days and can be reheated in the microwave.
