How To Make Cajun Shrimp In The Instant Pot

Ingredients Needed:

  • Shrimp: Whether fresh or frozen, it’s essential to thaw frozen shrimp before using them.
  • Bell Peppers: Opt for red and yellow bell peppers for their sweeter flavor profile, while green bell peppers tend to be slightly bitter.
  • Cajun Seasoning, Jerk Seasoning, or Your Preferred Seasoning: For a family-friendly option, consider milder seasonings such as smoked paprika, cumin, salt, and pepper.
  • Red Pepper or Chili Flakes (Optional)
  • Oil, Onion, Garlic, Salt, and Pepper
  • Vegetable Stock: If you prefer homemade, here’s a recipe you can use in your Instant Pot.

  • If opting for frozen shrimp, I advise thawing it beforehand. Finely dice the onion, mince the garlic, and chop the bell peppers.
  • Start by selecting the SAUTE function on your Instant Pot and allow it to heat for a minute. Then, add oil to the pot and sauté the onion until it turns soft and translucent. Once the onion is ready, add the garlic and cook until its fragrance fills the air. Turn off the sauté setting and deglaze the pot by adding a small amount of water.
  • Secure the lid and ensure the vent is set to SEALING. Then, select the PRESSURE COOK/MANUAL setting and adjust the cooking time to 0 minutes at LOW pressure. The Instant Pot will build pressure and automatically stop cooking. Once the cooking program completes, promptly release the steam.
  • Gently lift the lid and serve the dish warm over a bed of rice.

You’ll find that there’s plenty of sauce, as the shrimp release a significant amount of liquid. You can either serve it along with the rice or choose to discard it.

If desired, you can thicken the sauce to your preference. Begin by removing the shrimp and bell peppers, setting them aside. Then, select the SAUTE function and add a cornstarch slurry, which consists of 2 tablespoons of cornstarch mixed with 1-2 tablespoons of water. Allow the sauce to simmer while whisking continuously until it thickens. Once thickened to your liking, turn off the SAUTE setting.

Instant Pot Cajun Shrimp Tips

  • When pressure cooking, it’s crucial to opt for LOW pressure instead of high pressure to prevent the shrimp from overcooking. To select LOW pressure, simply press the “pressure cook” button multiple times until the low-pressure setting is displayed.
  • If using frozen shrimp, note that the pressure cooker will require additional time to come to pressure as the shrimp defrosts. Consequently, the bell peppers may be subjected to longer cooking, potentially resulting in mushiness. Therefore, it’s advisable to use fresh shrimp or thaw them before cooking.
  • For those preparing meals for children, consider utilizing a different seasoning blend, as Cajun seasoning can be too spicy for their palates. Instead, opt for milder options such as smoked paprika, cumin, oregano, salt, and pepper.
