This Instant Pot Creamy Cajun pasta has become one of the more popular recipes in our house.  It’s an easy and delicious pasta dish that can be made on a busy weeknight or for entertaining guests.  We served recently for a small family get together and received rave reviews.  
This recipe will serve 4-6 people depending on your serving size which makes it a great dish for entertaining a small group.  
We made this creamy pasta with sprimp, homemade Cajun seasoning and loads of other refresh ingredients.  But, what we love about this comfort food pasta is how versatile it is.

We chose to make this Cajun pasta with shrimp dish with homemade Cajun seasoning over pre-packaged seasoning as we find it has less sodium and artifical ingredients. 
However, feel free to use a pre-packaged seasoning, if prefered. The benefit of choosing a homemade seasoning is you can also adjust the ingredients to your families liking.  Our family loves food with a good ‘kick’ so this easy recipe was right up our alley.  
Regardless, this pressure cooker meal is almost guaranteed to turn out great!  I also find that the cream sauce, freshly grated Parmesan cheese and cream cheese cool of some of the heat.  If you prefer this pasta dish with less cream, feel free to decrease the heavy whipping cream or cream cheese.

WHAT TYPE OF PASTA SHOULD I USE?

What is great about this Instant Pot Creamy Cajun pasta is you can use any pasta of your choosing.  However, with a creamy pasta such as this, we love to use pasta shells that hold on to the cream sauce well.  Pasta shells such as penne pasta, fettuccini, rigatoni and more are our favorites. 
When cooking pasta in your pressure cooker, be sure to follow the tip before for cooking time.  

TIPS FOR COOKING PASTA IN YOUR INSTANT POT

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!

INGREDIENTS FOR INSTANT POT CREAMY CAJUN PASTA

  • 1 pound raw shrimp, peeled and deveined
  • 2 tablespoons olive oil
  • 1/2 yellow onion, chopped
  • 3 cups chicken broth
  • 1 pound Mezzi Rigatoni
  • 1 14.5 ounce can fire roasted tomatoes
  • 3 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

HOW TO MAKE CREAMY CAJUN PASTA WITH SHRIMP

  1. Turn on your Instant Pot and select the Saute mode on high.
  2. Add olive oil, roasted red diced tomatoes and onions.  Saute until onions are soft, about 3 minutes.  
  3. Add garlic. Continue to saute for an additional 2 minutes.
  4. 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.  
  5. Once shrimp are slightly pink in color, remove from Instant Pot with tongs and place aside in a large bowl.  
  6. Add heavy cream, creamy 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.
  7. Once the sauce has reached your desired thickness, add to large bowl with shrimp and set aside.  
  8. Select the ‘cancel’ function to reset the Instant Pot cooking function.  Select ‘Pressure Cook’ on high.  
  9. 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.  
  10. Once the timer beeps, quick release all pressure.  Carefully remove the lid.  
  11. Add shrimp and sauce to the pasta and mix until all ingredients are well combined.  
  12. Serve hot and enjoy!
