Why You Should Make This One-Pot Pasta

This recipe became a staple last summer when my garden produced an abundance of zucchini. It shows how a few pantry staples and a single pan can deliver a deeply satisfying meal. The sauce stays saucy, the zucchini melts into the pasta, and the whole dish comes together quickly with minimal fuss.

Top reasons to make this one-pot zucchini pasta:

  1. One-pot cooking means fewer dishes and easy cleanup.
  2. Shredded zucchini adds vegetables discreetly — perfect for picky eaters. Grating on the small holes blends it into the sauce; larger holes give more texture.
  3. Made from everyday pantry ingredients that are easy to keep on hand.
  4. Frozen shredded zucchini works well, so you can enjoy this year-round.
  5. No need to pre-thaw or drain fresh zucchini; the extra liquid helps create a saucier pasta. For frozen zucchini, drain excess water if it’s very watery.

Important Ingredient Notes

  • Small pasta: Choose small shapes like small shells, elbow macaroni, ditalini, or similar. Twelve ounces is about three cups.
  • Pasta sauce: A good quality jarred pasta sauce makes this simple and delicious. If using 24-ounce sauce instead of 28-ounce, add about 1/2 cup extra water or tomato sauce.
  • Milk: The milk adds creaminess so the finished dish isn’t strictly marinara. 1%, 2% or whole milk works well. Unsweetened non-dairy milks should also be fine.
  • Seasonings: Dried basil and oregano add background flavor. Stir in fresh basil at the end for a bright finish, if available.
  • Shredded zucchini: No need to peel — just trim the ends and shred on the small or large holes of a box grater. You’ll need roughly one medium zucchini (10–11 ounces) for this recipe.
  • Parmesan: Freshly grated Parmesan melts best and gives the creamiest texture. Serve extra at the table for sprinkling.

Cooking note: Authentic or thicker pasta shapes may require more cooking time and extra liquid. Add additional water as needed while simmering and adjust cooking time until pasta is tender.

Additional Notes

  • Different pastas cook at different speeds. If your pasta requires longer than the listed cook time, add a little more liquid and continue simmering until tender.
  • To prevent sticking, maintain a gentle simmer, stir often, and add small amounts of water if the sauce becomes too thick or the pasta starts to cling to the pan.
  • This pasta is delicious as a meatless main, and it pairs nicely with baked or cooked meatballs stirred in at the end so they’re coated in sauce.

This has been my go-to summer meal when zucchini is abundant: saucy, comforting, and ready in about 30 minutes without heating the oven.

Easy One-Pot Saucy Zucchini Pasta

Yield: 6 servings | Prep Time: 10 mins | Cook Time: 20 mins | Total Time: 30 mins

Ingredients

  • 12 ounces small pasta (small shells, elbow macaroni, ditalini), about 3 cups
  • 28-ounce jar pasta sauce (about 3 cups)
  • 2 cups water
  • 1 cup milk (1%, 2% or whole)
  • 1 teaspoon salt
  • 1 teaspoon dried basil
  • 1/2 teaspoon dried oregano
  • Pinch crushed red pepper (optional)
  • 2 to 3 cups shredded zucchini (no need to peel), about one medium 10–11 ounce zucchini
  • 1/2 cup freshly grated Parmesan cheese, plus extra for serving

Instructions

  1. In a deep skillet or wide saucepan combine the pasta, pasta sauce, water, milk, salt, dried basil, dried oregano and crushed red pepper (if using).
  2. Bring the mixture to a gentle simmer over medium heat, stirring often. Maintain a gentle simmer and continue cooking for 8–9 minutes, stirring frequently to prevent sticking.
  3. Stir in the shredded zucchini and simmer 2–3 more minutes, stirring often, until the pasta is tender. Add extra cooking time if your pasta needs it; add a little water as required to keep the sauce loose and prevent sticking.
  4. Remove from heat and stir in the Parmesan cheese. Taste and adjust salt if needed.
  5. Serve warm with additional Parmesan on the side. Note: the pasta will thicken as it rests.
  6. Optional: if serving with meatballs, cook the meatballs separately and stir them into the pasta at the end so they are coated in sauce.

Notes

Pasta sauce: If using 24 ounces of jarred sauce, add 1/2 cup extra water or tomato sauce to reach the saucy consistency called for. You can also substitute 28 ounces crushed tomatoes—if you do, consider doubling the dried herbs and adding 1 teaspoon brown sugar and a splash of soy sauce for balance.

Zucchini: Trim the ends and shred on the small or large holes of a box grater depending on the texture you prefer. Fresh or frozen shredded zucchini both work well; drain excess liquid from frozen zucchini if it is very watery.
