Instant Pot Jambalaya Recipe Shrimp and Sausage: Cajun Spice in 30 Minutes

This Instant Pot version brings authentic Cajun flavor to your weeknight table without the fuss. I developed this recipe after years of testing, ensuring the shrimp and sausage combination delivers restaurant-quality results in 30 minutes.

The secret is layering the spices and cooking the proteins perfectly. The andouille sausage adds smoky depth, while the shrimp soak up the bold Cajun seasoning. Every bite captures the essence of New Orleans.

What you get is a one-pot meal with tender shrimp, flavorful sausage, and perfectly cooked rice. The holy trinity of onions, bell peppers, and celery builds a rich, aromatic base that defines traditional jambalaya.

Serve it straight from the pot for a satisfying dinner that’s as easy as it is delicious.

Ingredients for Instant Pot Jambalaya Recipe Shrimp and Sausage

Authentic Cajun flavors start with smoky sausage, plump shrimp, and the holy trinity of veggies.

The sausage is non-negotiable here—andouille brings that smoky, spicy backbone. Check the butcher counter for the real deal, or grab Aidells at most supermarkets. Shrimp should be large (16-20 count) for even cooking. For the rice, long-grain white absorbs the flavors best. Basmati or jasmine work too but avoid instant rice (it’ll turn mushy).

No andouille? Kielbasa or smoked sausage in a pinch. Fresh shrimp only—frozen works too (thaw first). Out of Cajun seasoning? Mix one-third each paprika, garlic powder, and cayenne. The holy trinity (onion, bell pepper, celery) is sacred—don’t skip it. Trader Joe’s has great pre-diced mirepoix if you’re short on time.

This tastes even better the next day. Keeps 4 days in the fridge, freezes for 3 months. Store leftovers in airtight containers (the rice soaks up liquid, so add broth when reheating).

Step-by-Step Instructions for Instant Pot Jambalaya with Shrimp and Sausage

Here’s the method. Straightforward, tested, works every time.

Step 1: Sauté the Aromatics and Sausage

Set your Instant Pot to the sauté function and add the 2 tbsp olive oil. Once hot, add the sliced 12 oz Andouille Sausage and cook for 3-4 minutes until it starts to brown. This renders out the fat and builds the first layer of flavor.

Next, add the diced 1 whole Yellow Onion, diced 1 whole Green Bell Pepper, and diced 2 pieces Celery Stalks. Sauté for 5 minutes until the vegetables soften and the onion becomes translucent. Stir in the minced 4 cloves Garlic Cloves and cook for 30 seconds until fragrant—don’t let it burn.

Step 2: Toast the Rice and Add Spices

Stir in the 1.5 cups Long-Grain White Rice and cook for 2 minutes, stirring constantly. This toasts the rice slightly, which enhances its nutty flavor and prevents it from turning mushy. You’ll notice the grains become slightly opaque as they absorb the flavors of the sautéed vegetables.

Add the 2 tbsp Cajun Seasoning, 1 tsp Smoked Paprika, 1 tsp Dried Thyme, and 1 tsp Salt. Stir well to coat the rice and vegetables evenly with the spices. The mixture will be fragrant and deeply colored—this is the foundation of your jambalaya’s bold Cajun flavor.

Step 3: Pressure Cook with Broth and Tomatoes

Pour in the 2.5 cups Chicken Broth and add the 1 can Diced Tomatoes with their juices. Stir to combine, making sure to scrape up any browned bits from the bottom of the pot—this prevents burning. Add the 2 pieces Bay Leaves for a subtle herbal note.

Secure the lid, set the valve to sealing, and cook on high pressure for 5 minutes. The Instant Pot will take about 10 minutes to come to pressure before the cooking time begins. Once done, let the pressure release naturally for 10 minutes, then quick-release any remaining pressure.

Step 4: Add Shrimp and Finish Cooking

Open the lid and stir the jambalaya. The rice should be nearly tender at this point. Nestle the 1 lb Large Shrimp into the mixture, pressing them down slightly so they’re mostly submerged in the liquid. Secure the lid again and cook on high pressure for 3 minutes. The shrimp will cook perfectly in this short time.

Once the cooking time is complete, quick-release the pressure. Open the lid and remove the 2 pieces Bay Leaves. Stir gently to distribute the shrimp and sausage evenly. Let it sit for 5 minutes to allow the flavors to meld together. The jambalaya should be thick and hearty, with the rice fully cooked and the shrimp opaque and pink.
