Keto noodles

For this low carb macaroni salad recipe, you have a couple different options for keto noodles and they range in different net carb totals as well as if they contain gluten or not.

  • Lupin flour pasta – This is my favorite option as it is gluten free and low carb. The ingredients are fairly clean and there are only 6 g net carbs per 1/4 container. And this makes a lot of pasta so really each bag is about 8 servings making each serving 3 g net carbs.


  • Shirataki noodles – Another gluten free and very low carb option. Shirataki noodles are Japanese gelatinous noodles made from the konjac yam. The noodles are mostly comprised of water and glucomannan. Glucomannan is a water soluble fiber which means these noodles have almost ZERO net carbs! Shirataki noodles have very little flavor on their own so they take up the flavor of the dish they are made with. If prepared correctly, they are a wonderful substitute for pasta and noodles in a keto recipe.


  • Wheat based keto macaroni – These look the most like actual macaroni noodles; however, they do contain wheat and are a little higher in carbs. 7 grams net carbs per 2 oz serving.

Storage information

Store any leftover keto macaroni salad in the refrigerator for up to 3 days. This recipe can be made ahead of time and stored in the fridge as well. I think it tastes even better the next day since the flavors have a chance to meld together.
