  • 8 oz thin linguini pasta
  • 1 small onion diced. about 1 cup
  • 2 cups heavy cream
  • cup pasta water reverse from cooking pasta
  • 1 tbsp. paprika
  • ¾ cup grated parmesan cheese or 6 oz. cream cheese
  • 1 tsp. salt
  • 1 tsp. black pepper
  • 2 tbsp. Cajun seasoning low salt
  • 1 tsp. cayenne pepper optional
  • 1 tbsp. olive oil


  • 2 lbs. shrimp
  • 1 tbsp. olive oil
  • ¾ tsp. garlic powder
  • 1 tsp. onion powder
  • 1 ½ tsp. paprika
  • 2 tbsps. Cajun seasoning low salt


  • Cook pasta al dente, according to package directions.
  • Meanwhile, season the shrimp with some paprika, onion powder, garlic powder and low salt Cajun seasoning.
  • Pan sear the shrimp for about 5-7 minutes with olive oil until they are almost cooked through. Set aside.
  • In the same pan, sauté the onion until they are caramelized in one 1 tbsp of olive oil.
  • Add in the spices, pasta water and heavy cream.
  • Simmer on low for about 2-3 minutes and then add in the grated parmesan cheese. Give it a stir and then simmer for a couple more minutes.
  • Add in the cooked pasta and toss to coat really well with the creamy Cajun sauce.
  • Then add in the shrimp and mix everything together well. Cover and simmer for 3-4 minutes on low heat. Remove and serve!
  • You can garnish with some pepper flakes or chopped parsley before serving.



  • Ideally cook the pasta al dente, so it will come out with enough bite after you simmer it in the sauce.
  • After dropping the pasta into the boiling water, stir immediately to avoid the noodles sticking.
  • Make sure to reserve some pasta water for the sauce, this helps make it more robust.
  • To save time, opt for shelled and deveined shrimp.
  • Shrimp cooks quick, so keep an eye it on when pan searing. They should turn opaque pink and form a 'C' shape.
  • Ideally opt for low salt Cajun seasoning I have bought so many brands of Cajun seasoning and could not handle most of them because they are so salty. So be sure to grab a good one.
  • If you are not a fan of heavy cream or want to reduce the fat, you can use half and half instead (half milk , half cream for the amount required).
  • Top with some red pepper flakes for an extra kick of heat.
