Crab Pasta Recipe with Pesto, Mushrooms & Tomatoes

Crab Pasta Recipe with Pesto, Mushrooms & Tomatoes is one of my family’s favorite dinner recipes. I’ve been making this pesto pasta recipe for over 20 years.

When I first started making this crab pasta recipe, pesto was only available in specialty gourmet stores in teeny, expensive jars.

Luckily, back then I came across envelopes of pesto mix at my grocery store. It was affordable and worked well when combined mushrooms, tomatoes, and imitation crab.

Over the years, my crab pasta recipe has made several changes. Sometimes I leave out the tomatoes and sometimes I use canned crab instead of imitation crab.

No matter how you make it, if you’re a fan of seafood pasta recipes, you’ll love this crab pasta.

How to make a gluten free crab pasta

Go gluten free with gluten free pasta 

I now make gluten free crab pasta. (You don’t have to unless you’re gluten free.)

There are so many brands of delicious gluten free spaghetti on the market now that my family doesn’t mind this too much.

Gluten free imitation crab?

If you’re gluten free and are using imitation crab, make sure the brand you’re using is certified as gluten free. Not all brands are.

You can also canned crab, which is naturally gluten free.

Another option for this pesto pasta recipe is using bay shrimp instead of imitation crab.

My family loves this recipe for crab pasta

Even though most kids don’t like crab, mushrooms or pesto, my children love crab pasta recipe.

Maybe it’s the sweetness of the imitation crab or the sprinkling of Pecorino Romano cheese. (You can also use Parmesan cheese.)

They love it reheated the next day, too.

I’ve even eaten this crab pesto pasta recipe cold. In my opinion, the mark of a good pasta dish is that it should taste as good cold as it does hot. Yum!

Tomatoes:

Make sure to use cherry tomatoes instead of grape tomatoes (and a variety of colors) since they're sweeter and more delicious.
