This delicious and colorful California Pasta Salad is always a hit at parties! Make it a day ahead if you want; the flavors only get better as it sits!

Ironically, I discovered California Pasta Salad during my recent trip home to Wisconsin (if you’re new here, it’s ironic because I actually live in California).

Among the non-stop backyard bonfires, lake-front picnics, and general summer merriment, one of my friends brought the most amazing Pasta Salad in recent memory.

It’s a giant bowl of chewy noodles, colorful veggies, and the best Italian salad dressing I’ve ever had. And unlike every other version of California Pasta Salad you’ll find on the Internet, my dressing is made from scratch!

I envision you all making this pasta salad in late summer when your gardens are overflowing with zucchini (some too big for their own good; you just can’t pick them fast enough!), cucumbers, tomatoes, and bell peppers. I hope you do! It’s so good!

While this recipe originated with Taste of Home in 1992, bloggers have been reposting the recipe over the last few years. However, every single version I find still uses store-bought Italian salad dressing.

We can do better!

Red Wine Vinaigrette takes 2 minutes to make, tastes way better, and is the perfect canvas on which to paint the extra flavors that go in to this dressing (sesame seeds, poppy seeds, celery seeds, paprika, and parmesan cheese).

If you’re reading this, Mom, you may substitute a bottle of store-bought Italian (just add those 5 ingredients I listed in the previous sentence).

The flavors just get better as the salad sits! You’ll want to give it at least 2 hours, but feel free to leave it in the fridge overnight.

  1. This recipe looks so yummy and perfect for a planned potluck that I am going to in a few weeks. One question: do you use fresh grated parmesan cheese or can you use the grated dry parmesan cheese that come in a plastic container the you sprinkle on spaghetti?

    Thank you,5 stars

    1. Hi Mary, for this I would use the grated dry parm from the plastic container. I like that better on pasta salads because it’s saltier and I just LOVE the way it clings to the noodles. But it’s totally your preference, if you have a chunk of regular parm sitting around and you want to grate it, that’s great. But where I come from (Wisconsin) everyone uses the plastic container on pasta salads because they always have it on hand. I think we love what we grew up with! I hope this helps. I hope everyone likes the recipe! -Meggan
