Tips For Success

  • Season your pasta water with salt for flavorful noodles and sauce. 
  • Cook the pasta slightly less than usual as the pasta will continue to cook as you make the sauce. 
  • Use a mug to scoop out some of the pasta water before draining. 
  • If your sauce is too dry, add a little extra pasta water. 


  • Swap/Add Veggies - Yellow squash and eggplant also work well in this dish.
  • Add Fresh Herbs - Toss in some fresh basil or your favorite fresh herbs.
  • Make it Spicy - Add some crushed red pepper flake with the rest of the seasonings to give this recipe a spicy kick. 
  • Add Protein - Toss is sauteed chicken breast or cooked shrimp. 

Budget-Friendly Tips 

  • Plant a Garden - Both zucchini and cherry tomatoes are easy to grow, and doing so can save you money. 
  • Make Friends with a Gardener -  Gardeners are known to leave bags of zucchini and squash all over the place when their garden is producing. Make friends with a gardener so you can be the recipient of this wonderful gift. 
  • Stock Up on Pasta - Pasta is shelf-stable, so buy in bulk or when it’s on sale. 
  • Store Cheese in The Freezer - If you can’t use all of your parmesan cheese, store it in the freezer for later use.
