Instant Pot Cajun Chicken and Rice Recipe

Instant Pot Cajun Chicken and Rice is a budget-friendly, one-pot dinner that delivers big flavor with minimal fuss. Tender, juicy boneless chicken thighs tossed in Cajun seasoning combine with colorful bell peppers, onions, celery and long-grain white rice to make a comforting weeknight meal that finishes in about 30 minutes.

Cajun Chicken Rice in the Instant Pot

This recipe is all about simple techniques that build deep flavor: a quick flash marinade, a short braise to brown the chicken, a brief sauté of the vegetables to draw out sweetness, and then pressure cooking to finish everything together. The result is a vibrant, well-seasoned rice and chicken dish with bright pepper notes and a gentle heat from the Cajun blend.

You can use boneless, skinless chicken thighs for richer flavor and juiciness, or boneless chicken breasts if you prefer leaner meat. Adjust the amount of Cajun seasoning to your taste — the recipe below leans toward a bolder, spicier profile, but you can reduce the seasoning and skip paprika if you prefer a milder version.

Ingredients

• Chicken: 1.66 pounds boneless, skinless chicken thighs, cut into large chunks. Chicken breasts may be substituted.
• Rice: 2 cups long-grain white rice, rinsed thoroughly and drained.
• Liquid: 2 cups plus 50 ml water or low-sodium chicken stock.
• Onion: ½ cup yellow onion, roughly chopped.
• Celery: ½ cup, finely chopped.
• Bell peppers: ½ cup each of green, yellow, orange and red, finely chopped (or a mix totaling about 2 cups).
• Tomato paste: 1 tablespoon, diluted with 2 tablespoons water.
• Cajun seasoning: 2 tablespoons, adjust to taste.
• Paprika: 1½ teaspoons (optional).
• Oil: 3 tablespoons extra virgin olive oil.

What is Cajun seasoning?

Cajun seasoning is a savory dry spice blend commonly made from onion and garlic powders, salt, black pepper, cayenne or chili powder, oregano and thyme. Many commercial and homemade blends also include paprika and additional chili flakes. The mix delivers a smoky, garlicky, pepper-forward profile with heat from cayenne — ideal for chicken, seafood, rice dishes and grilling.

Key Tips for Best Results

• Rinse the rice thoroughly: Washing rice until the water runs clear removes excess surface starch and helps produce light, separate grains instead of gummy rice.
• Braise the chicken: Browning the chicken on both sides before pressure cooking adds depth and caramelized flavor. This step is optional but highly recommended.
• Sauté the vegetables briefly: Cook onions until translucent, then add peppers and celery for a minute to draw out natural sweetness.
• De-glaze the pot: After sautéing and braising, pour in the liquid and scrape the bottom of the pot to remove any stuck bits. This prevents an Instant Pot “BURN” warning and improves flavor.
• Water-to-rice ratio: For 2 cups rinsed long-grain white rice use 2 cups plus 50 ml of liquid for fluffy, well-cooked rice.
• Rest before serving: Allow the finished dish to sit 10–15 minutes to let steam redistribute for even fluffiness.

How to make Instant Pot Cajun Chicken and Rice — Step by Step

Step 1 — Flash marinate and braise the chicken

Optional: toss the chicken pieces with a few dashes of Cajun seasoning, a little paprika and salt. Set your Instant Pot to Sauté on HIGH, add oil, and brown the chicken briefly on both sides until lightly golden. Remove and set aside.

Step 2 — Sauté the vegetables

Using the same oil, set Sauté to NORMAL and cook the onions until they begin to turn translucent. Add the chopped bell peppers and celery and cook for another 1–2 minutes to soften slightly.

Step 3 — Add seasoning, rice and pressure cook

Stir in the Cajun seasoning (and paprika, if using) and mix. Return the browned chicken to the pot. Pour in the measured water or chicken stock and add the diluted tomato paste. Scrape the pot bottom well to de-glaze and remove any stuck bits. Gently add the rinsed, drained rice, folding it into the liquid without over-stirring to avoid breaking the grains.

Seal the lid and pressure cook on HIGH for 5 minutes. When the cook cycle ends, allow a 10-minute natural pressure release, then release remaining pressure manually. Open the lid, fluff the rice gently with a fork, and let the dish rest 10 minutes before serving for best texture.

Storage, reheating and freezing

Refrigerator: Store leftovers in airtight containers for up to 5 days. Reheat gently in the microwave with a sprinkle of water to keep the rice moist, or warm in a skillet over medium heat with occasional stirring.

Freezer: This dish freezes well for up to 2 months. Portion into freezer-safe bags for easy grab-and-reheat meals. Thaw overnight in the fridge before reheating for best texture.

Notes and helpful reminders

1. Measuring conversions used: 1 cup = 240 ml, 1 teaspoon = 5 ml.
2. Braising means quickly browning the meat to build flavor — a short step that makes a noticeable difference.
3. If you skip braising, you can still flash-marinate the chicken and add it directly to the pot; sauté for 2–3 minutes with the veggies before pressure cooking.
4. Rinsing rice is essential for non-sticky, separate grains — rinse until the water runs clear and drain well.
5. Use the same measuring cup for rice and liquid and follow the specified liquid ratio for best results.
6. To reduce heat, cut back on Cajun seasoning and omit paprika.
7. Allow the finished dish to rest for 10–15 minutes for optimal fluffiness.
