Ingredients

  • 1 pound raw shrimp, peeled and deveined 
  • 2 tablespoons olive oil
  • 1 tablespoon minced garlic
  • 1/2 yellow onion, chopped
  • 1 14.5 ounce can fire roasted tomatoes
  • 3 cups chicken broth 
  • 1 pound Mezzi Rigatoni
  • 4 tablespoons Cajun seasoning (you can use prepackaged Cajun seasoning, if needed)
  • 1 1/2 cups parmesan cheese 
  • 1 1/2 cups heavy cream 
  • 4 ounces cream cheese
  • Pinch of salt to taste 

Instructions

  • Turn on your Instant Pot and select the Saute mode on high. 
  • Add olive oil, roasted red diced tomatoes and onions.  Saute until onions are soft, about 3 minutes.
  • Add garlic. Continue to saute for an additional 2 minutes. 
  • Toss shrimp in cajun seasoning until coated evenly.  Place shrimp into Instant Pot and saute for 2-3 minutes on each side until shrimp are slightly pink in color.  
  • Once shrimp are slightly pink in color, remove from Instant Pot with tongs and place aside in a large bowl.  
  • Add heavy cream, cream cheese, Parmesan cheese and stir so all ingredients in the Pot are mixed together well.  Saute until thickened, about 10 minutes. NOTE: do not clean out the pot.  You will want all the Cajun goodness to cook into the sauce. 
  • Once the sauce has reached your desired thickness, add to large bowl with shrimp and set aside.  
  • Select the 'cancel' function to reset the Instant Pot cooking function.  Select 'Pressure Cook' on high. 
  • Add pasta shells and chicken broth.  Stir until mixed well.  Pressure cook on high for 3 minutes.  NOTE: we like our pasta very slighly al dente.  If you like yours more soft, you may want to cook for 4 minutes.
  • Once the timer beeps, quick release all pressure.  Carefully remove the lid.
  • Add shrimp and sauce to the pasta and mix until all ingredients are well combined. 
  • Serve hot and enjoy! 

STOVE TOP

  • In a large pan over medium heat, add olive oil onions.  Saute until onions are soft, about 3 minutes.  
  • Add garlic. Continue to saute for an additional 2 minutes. 
  • Toss shrimp in cajun seasoning until coated evenly.  Place shrimp into your pan and saute for 2-3 minutes on each side until shrimp are slightly pink in color.  
  • Once shrimp are slightly pink in color, remove from the pan with tongs and place aside in a large bowl.
  • Add heavy cream, cream cheese, Parmesan cheese and stir so all ingredients in the Pot are mixed together well.  Saute until thickened, about 10 minutes. NOTE: do not clean out the pot.  You will want all the Cajun goodness to cook into the sauce. 
  • Once the sauce has reached your desired thickness, add to large bowl with shrimp and set aside. 
  • In a medium pot over medium heat, bring water with a pinch of salt to boil. 
  • Add pasta shells and cook for 4-5 minutes or until pasta has reached your desired pasta softness.
  • Mix pasta shells, shrimp and sauce together until well combined.  Add any additional cajun seasoning or salt or pepper to taste. 
  • Top with additional Parmesan cheese.  Serve hot and enjoy!

Notes

When cooking Instant Pot recipes with pasta feel free to choose any pasta shell you might prefer.  Regardless of which pasta you choose, be sure to follow the cooking times indicated on the box of your pasta choice.  Whatever the box says - cut it in half and subtract 2 minutes. 
For example, if the box says to cook for 10 minutes, you will cut that in half (5) and subtract 2.  All together you would cook for 3 minutes.  
If for any reason you don't feel as though your pasta is cooked enough, you can always place the lid back on your Instant Pot and pressure cook again for 0 minutes.  That should do the trick!
