Zucchini production is starting to slow down in my garden, but I’m still getting a few zucchinis or yellow straight-neck squash every couple of days.  The other thing that’s abundant this time of year is basil, so I’ve been freezing basil and last weekend I made a huge amount of Basil Pesto with Lemon.  I guess it was that basil pesto that inspired this Pasta with Zucchini and Basil Pesto because when I told my nephew Jake what were going to make he asked me where the recipe was and I tapped the side of my forehead.

This recipe was one of those spontaneous cooking ideas that just appear in my brain:  why wouldn’t a little zucchini sauteed with garlic taste great mixed into pasta with basil pesto?  This is so easy you don’t really need a recipe, but we wrote it down in case anyone wants the particulars! And this isn’t a low-carb recipe, but if you are watching carbs you could make a delicious carb-conscious variation by using more zucchini and a lot less pasta.

Of course there are people who don’t have a garden that’s mass-producing basil, and if that’s the case you can certainly make this with purchased basil pesto in a jar.  But if you do have basil and haven’t made your own pesto, I do highly recommend my recipe with just a touch of lemon. And maybe I’m just in a basil mood lately, but this year’s pesto seemed like some of the best I’ve ever made.

How to Make Pasta with Zucchini and Basil Pesto:

(Scroll down for complete recipe with nutritional information.)

  1. Start a pot of water boiling for the pasta, salting the water.  (That would certainly have been a boring photo, right?)
  2. Then heat 1 T olive oil in a big frying pan, add the minced garlic and saute just about a minute. 
  3. Once you can start to smell the garlic, add all the zucchini, season with salt and fresh ground black pepper, and saute until the zucchini is as tender as you’d like it.
  4. By now the pasta water should be boiling, so throw the pasta into the pot.
  5. I used Basil Pesto with Lemon that I thawed from the freezer. You can use more or less pesto to taste, but 2/3 cup seemed about right to me.
  6. When the zucchini is tender-crisp, stir in the pesto and gently combine with the zucchini.  (If the pasta isn’t done, turn the heat off on this for a minute.)
  7. When the pasta is done, scoop out 1/2 cup pasta cooking water before you drain it. (I don’t like to wash dishes, so I used the same measuring cup I measured the pesto in!)
  8. Drain the pasta into a colander placed in the sink.
  9. Then mix the hot pasta into the zucchini-pesto mixture, adding as much of the pasta cooking water as you need to get the mixture nicely combined.
  10. Serve hot. Leftovers can be stored in the fridge for a few days and gently reheated in the microwave.

This easy and quick Pasta with Zucchini and Basil Pesto is a perfect family dinner during zucchini season! Use even less pasta and more zucchini and pesto if you prefer.


  • 12 oz. dry Penne pasta (or similar shape)
  • salt, for pasta cooking water
  • 2 medium zucchinis (see notes)
  • 1 T minced fresh garlic
  • 1 T olive oil
  • salt and fresh ground black pepper, for seasoning zucchini
  • 2/3 cup Basil Pesto  of your choice (see notes)
  • 1/2 cup pasta cooking water


  1. Fill a large pot with water, add about 2 tsp. salt, and let the water come to a boil while you prep other ingredients.
  2. Wash zucchini if needed, cut off ends, then cut in half lengthwise and slice into half-moon slices. (If the zucchini is really large, you might want to cut it into fourths before slicing.)
  3. Measure out 2/3 cup basil pesto, and mince enough fresh garlic to make 1 tablespoon.
  4. As soon as the water comes to a boil add the pasta, stir, and reduce heat to medium, or high enough to keep the water at a gentle boil.
  5. Cook pasta as long as directed on the package, then measure out 1/2 cup pasta cooking water before you drain the pasta. (Don’t overcook, the pasta should still have some bite to it.  I cooked my pasta exactly 9 minutes.)
  6. While pasta is cooking, heat the olive oil in a very large frying pan (big enough to hold all the pasta when it’s cooked.)  When oil is hot, add the minced garlic, turn heat down to medium, and saute just until you can start to smell garlic, about one minute.  (Don’t let the garlic burn!)
  7. Then add the sliced zucchini, season to taste with salt and fresh ground black pepper, and saute until the zucchini is tender-crisp, about 5 minutes.  (Taste a piece to see if it’s as done as you like it. I stop cooking when it’s still a little crisp.)
  8. Add the pesto to the cooked zucchini and gently stir to combine. (If the pasta is not done yet, turn off the heat.)
  9. Add the drained cooked pasta to the zucchini/pesto combination and gently mix together, adding as much pasta cooking water as you think it needs to get the mixture nicely combined.
  10. Serve hot. This will keep in the fridge for a day or two, but it’s best freshly made.


I used Basil Pesto with Lemon for this recipe. Use more or less pesto to taste. I used zucchini almost 10 inches long. Recipe created by Kalyn.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
If this Penne Pasta with Zucchini and Basil Pesto is made with with Dreamfields or whole-grain pasta, you could eat a small serving of this for phase 2 or 3 of the South Beach Diet, but I would use portion control and serve with something like Ottolenghi’s Perfect Lettuce Salad.  It’s too high in carbs for traditional low-carb diets.
