Ingredients

- 1 tablespoon vegetable oil or avocado oil, sunflower oil, corn oil
- 1 small yellow onion, diced
- 2 cloves garlic, minced
- 1 pound (450 grams) raw shrimp, deveined and peeled
- 2 tablespoons Cajun seasoning
- ¼ teaspoon chili flakes (optional, for added heat)
- ¾ teaspoon salt, or to taste
- 3 small bell peppers, diced (yellow, green, and red for color)
- ¼ cup vegetable stock or chicken stock

How To Make Instant Pot Cajun Shrimp
Step 1: Sauté the Aromatics
Start by turning your Instant Pot to the sauté mode. Add 1 tablespoon of your chosen oil to the pot. Once the oil is hot, add the diced yellow onion and sauté for 2-3 minutes until it becomes translucent. Next, add the minced garlic and sauté for an additional minute, stirring constantly to avoid burning.
Step 2: Add the Shrimp and Spices
Now it’s time to add the star of the show: the shrimp! Sprinkle the Cajun seasoning and chili flakes over the shrimp, ensuring they are evenly coated. Toss everything together for about 2 minutes, allowing the shrimp to absorb those fantastic flavors.
Step 3: Incorporate the Vegetables and Stock
Add the diced bell peppers to the pot, mixing them in with the shrimp and onions. Pour in the vegetable or chicken stock, scraping up any bits stuck to the bottom of the pot. This will add even more flavor to your dish.
Step 4: Pressure Cook
Close the lid of the Instant Pot and ensure the valve is set to sealing. Cook on high pressure for just 1 minute. Yes, you read that right, just 1 minute! Once the cooking time is up, allow the pot to naturally release pressure for 5 minutes before performing a quick release for any remaining pressure.
Step 5: Taste and Garnish
After releasing the pressure, carefully open the lid. Give the shrimp a gentle stir to combine the flavors. Taste and adjust seasoning, adding more salt or Cajun spice if desired. Serve hot, garnished with chopped fresh parsley or cilantro.
Expert Tips
To ensure your Instant Pot Cajun Shrimp turns out perfectly, keep these tips in mind:
- Use quality shrimp: Fresh or properly frozen shrimp will provide the best texture and flavor.
- Don’t overcook: The shrimp cooks very quickly, so it’s important to not extend the cooking time. They’ll become rubbery if overcooked.
- Adjust spice levels: If you prefer a milder dish, reduce the Cajun seasoning or skip the chili flakes.
- Serve immediately: This dish is best enjoyed fresh, as the shrimp can lose their tenderness if left to sit.
Variations and Customizations
There are many ways to personalize this Instant Pot Cajun Shrimp recipe:
- Add extra vegetables: Consider adding zucchini, corn, or even okra for added texture and nutrients.
- Swap the protein: If shrimp isn’t your thing, try substituting with chicken or tofu, adjusting the cooking time as necessary.
- Make it creamy: Stir in a splash of heavy cream at the end for a rich, creamy sauce.
- Serve over grains: This dish is fantastic served over rice, quinoa, or even pasta to soak up all that delicious sauce.
How to Store Leftovers
If you happen to have leftovers (which is rare, given how delicious this dish is), here’s how to store them:
– Allow the Cajun shrimp to cool completely, then transfer them to an airtight container.
– Store in the refrigerator for up to 2 days. Reheat gently on the stovetop or in the microwave until warmed through.
– If you’d like to freeze it, portion into freezer-safe containers and freeze for up to 2 months. Thaw in the fridge overnight before reheating.
