Flip them over and sprinkle with another teaspoon of Cajun Seasoning. Allow the shrimp to sauté for 2-3 more minutes, or until the they have turned pink and begin to firm up. The shrimp will cook quickly, so be careful not to over cook them.

You’ll want to cook for another 3-5 minutes or until the sauce has thickened so that it will coat the shrimp really well.

Rinse the Palmini under cold water for a couple minutes. After they’ve drained, add them along with the shrimp back to the skillet and cook for another minute or until everything is heated through.

Tips on Making the Best Keto Creamy Cajun Shrimp

  • The first tip to making the perfect low carb shrimp recipe is selecting high quality shrimp. You need to look for local, wild-caught shrimp. Try to avoid farmed shrimp because most likely they been treated with chemicals, antibiotics or pesticides.
  • To ensure you get a really fresh, pronounced flavor, grate your Parmesan cheese right before using it. You just can’t get that from pre-grated cheese.
  • If your sauce is a little thin, just add more cheese and allow to cook a little longer. The sauce will thicken as it cooks.
  • If you don’t have Parmesan cheese on hand, you can substitute with Asiago or Romano cheese and it will be equally as delicious.
  • In case you have leftovers, place them in a freezer safe bag, let all the extra air out the bag and zip it closed, making sure the shrimp are covered with sauce. It will keep in the freezer for up to 3 months.

Is Palmini Pasta Keto Friendly?

Absolutely! Palmini Noodles is made from harvested heart of palm trees. And because it is made from a low carb vegetable and does not contain ANY grains, like traditional pasta, Palmini makes the perfect noodle substitution. They have several size noodles to choose from. The Palmini Linguini is perfect for this recipe but if you make Zucchini Lasagna recipe, you can substitute the zucchini for Palmini Lasagna Noodles.

Not only is Palmini low in carbs, it is rich in fiber, vitamins B2, B6, and C. It also contains zinc, potassium, riboflavin, magnesium and iron. Who could ask for more?

What Does Palmini Pasta Taste Like?

When you first open the can, you’ll notice a mild scent to the Palmini. After rinsing it well under cold water, the flavor becomes very mild. It stands up better in rich sauces, such as this Cajun sauce or a zesty marinara than in a mild butter reduction. Hearts of palm pasta has the texture much like al dente pasta.

    Just made this tonight – this was excellent. My husband is not a shrimp fan and he had two servings! It was also our first time trying Palmini noodles and we liked them. My only change was I put the shrimp in a ziplock back with the seasoning and shook them up to get better coverage prior to cooking. This is going in our regular rotation. Love your Cajun seasoning too! I think this would be good with chicken tenderloins for non fish lovers. Thanks for the recipe.

    1. Thank you so much for the kind remarks. I think you’re right about chicken tenders being good this way too. Thanks for the suggestion.

  2. 5 stars
    Made this for dinner tonight and it was delicious! My husband is a pretty picky eater and he inhaled it. Sauce was fantastic and the palmini were a pleasant surprise. Glad I found this recipe!

    1. That is wonderful! Anytime a recipe is husband approved, that definitely makes it a keeper. I am so glad you guys loved it.

  3. 5 stars
    There are only 5 stars to rate this but it is so much more than 5 stars! I made this yesterday for dinner! I am on a Keto diet and my husband is not so I put his on angel hair pasta and mine on Zucchini. When we started dinner my husband kept saying this was a homerun and soooo good! Then when I went to put the leftovers in the bowl to keep he said “Don’t waste one drop of it!” He LOVED IT and so do I! Thank you Julianne!

    1. You are welcome and this is SO awesome to hear! I love that it is even husband-approved. 😊

  4. 5 stars
    WOW! Brilliant recipe! My BF and I ate the whole thing and we are stuffed. You re a genius. ❤️
