Instant Pot Chicken and Peppers recipe

The first time I made this Instant Pot Chicken and Peppers, it was born out of sheer necessity. It was one of those evenings where the day had completely run away from me, and the thought of standing over a hot stove for an hour felt impossible. I had chicken breasts in the fridge and a trio of colorful bell peppers on the counter that were on the verge of losing their crispness. My Instant Pot, my trusty kitchen sidekick, seemed to be calling my name. I half-heartedly chopped the vegetables and chicken, threw them in the pot with some pantry seasonings and a can of tomatoes, and sealed the lid with a hopeful sigh. Less than 30 minutes later, the aroma that filled my kitchen was nothing short of miraculous. It was rich, savory, and smelled like a meal that had simmered for hours. When I opened the lid, I was greeted by a vibrant stew of perfectly cooked, tender chicken and bright, flavorful peppers in a luscious tomato sauce. I served it over a simple scoop of rice, and my family devoured it. My husband, who is usually my toughest critic, looked up from his clean bowl and said, “This is a keeper. A definite keeper.” He was right. It has since become a cornerstone of our busy weeknight rotation, a testament to the fact that you don’t need hours to create a meal that is deeply comforting, healthy, and incredibly delicious.

Ingredients: A Symphony of Color and Flavor

This recipe relies on a simple list of fresh ingredients and pantry staples to create a dish that is bursting with flavor. The quality of your ingredients will shine through, so choose the best you can.

Core Ingredients:

• Olive Oil: 2 tablespoons.
• Boneless, Skinless Chicken Breasts: 1.5 lbs (about 680g), cut into 1-inch cubes.
• Yellow Onion: 1 large, chopped.
• Bell Peppers: 3 large, of various colors (e.g., red, yellow, orange), seeded and sliced into strips.
• Garlic: 4 cloves, minced.
• Chicken Broth: ½ cup, low-sodium.
• Canned Diced Tomatoes: 1 can (14.5 ounces or 411g), undrained (fire-roasted for extra flavor).
• Tomato Paste: 2 tablespoons.
• Dried Oregano: 1 teaspoon.
• Dried Basil: 1 teaspoon.
• Smoked Paprika: ½ teaspoon.
• Salt: ¾ teaspoon, or to taste.
• Freshly Ground Black Pepper: ½ teaspoon.

• Fresh Parsley: ¼ cup, chopped, for garnish.
• Grated Parmesan or Provolone Cheese: For serving.

A Deeper Look at the Ingredients

Understanding the role of each component will help you master and customize this dish.

The Chicken: While this recipe calls for chicken breasts, chicken thighs are also an excellent choice.

• Chicken Breasts: They cook quickly and, thanks to the pressure cooker’s moist environment, stay tender and juicy. They are a lean source of protein and shred nicely if you prefer that texture.
• Chicken Thighs: Boneless, skinless chicken thighs will yield an even more succulent and flavorful result due to their higher fat content. They hold up beautifully to pressure cooking and become melt-in-your-mouth tender.

The Bell Peppers: The star vegetable of the dish.

• Color Matters: Using a variety of colors isn’t just for looks; it’s for flavor. Red, orange, and yellow bell peppers are sweeter and milder, while green bell peppers have a more savory, slightly bitter taste. The combination creates a wonderful flavor profile.
• The Cut: Slicing the peppers into strips about ½-inch thick is ideal. If they are cut too thinly, they risk turning to mush under pressure. The thicker strips will soften but still retain some of their texture.

The Sauce Base: This is what brings everything together.

• Chicken Broth: This is your primary cooking liquid. It’s essential for bringing the Instant Pot to pressure and for deglazing the pot to prevent the dreaded “BURN” notice.
• Diced Tomatoes: Fire-roasted diced tomatoes are a fantastic choice here, as they add a subtle smokiness and depth that regular diced tomatoes don’t have. Do not drain them; the liquid is part of the sauce.
• Tomato Paste: This is a concentrated flavor powerhouse. It adds a rich, deep tomato flavor and a beautiful color to the sauce that you can’t get from diced tomatoes alone.

Instructions: Your Step-by-Step Guide to Pressure Cooking Perfection

Follow these instructions closely for a flawless result. This recipe is designed for a 6-quart Instant Pot, but can be adapted for an 8-quart model.

Step 1: Sauté the Aromatics and Chicken
Turn your Instant Pot on by selecting the Sauté function and adjust it to “More” or “High.” Once the display reads “Hot,” add the 2 tablespoons of olive oil. Add the chopped onion and sauté for 3-4 minutes, stirring occasionally, until it begins to soften and become translucent. Add the minced garlic and cook for another minute until fragrant. Pat the chicken cubes dry with a paper towel and season them generously with salt and pepper. Add the chicken to the pot in a single layer (you may need to do this in two batches to avoid overcrowding). Cook for 2-3 minutes per side, just until the outside is lightly browned. The chicken will not be cooked through at this stage. This browning step builds a crucial layer of flavor. Remove the browned chicken and set it aside on a plate.

Step 2: The All-Important Deglazing Step
With the chicken removed, pour the ½ cup of chicken broth into the hot pot. Use a wooden spoon or flat-edged spatula to scrape up all the browned bits (known as fond) that are stuck to the bottom of the pot. This step is critical. Not only does the fond contain immense flavor, but failing to deglaze the pot is the number one cause of the “BURN” error message on an Instant Pot. Scrape diligently until the bottom of the pot is smooth. Press Cancel to turn off the Sauté function.

Step 3: Layer the Ingredients (The Right Way)
Return the browned chicken and any accumulated juices back into the pot. Sprinkle the dried oregano, dried basil, and smoked paprika over the chicken. Add the tomato paste and the can of undrained diced tomatoes. Stir everything together gently. Finally, layer the sliced bell peppers on top of the chicken and sauce mixture. Do not stir the peppers in. Placing them on top helps prevent them from becoming overcooked and mushy.

Step 4: Pressure Cook
Secure the lid on the Instant Pot, ensuring the steam release valve is set to the Sealing position. Select the Pressure Cook or Manual button and set the timer for 8 minutes at High Pressure. The Instant Pot will take about 10-15 minutes to come to full pressure before the cooking countdown begins.

Step 5: Release the Pressure and Finish the Sauce
Once the 8-minute cooking cycle is complete, allow the pressure to release naturally for 5 minutes. This helps the chicken stay tender. After 5 minutes, carefully perform a Quick Release by moving the steam release valve to the Venting position. Be cautious of the hot steam. Once the pin has dropped, it is safe to open the lid. The sauce will appear thin at this point. To thicken it, select the Sauté function again. In a small bowl, whisk together the 1 tablespoon of cornstarch and 2 tablespoons of cold water to create a smooth slurry. Pour the slurry into the pot and stir gently. Let the sauce simmer for 2-3 minutes, stirring, until it has thickened to your desired consistency.

Step 6: Final Touches
Press Cancel to turn off the heat. Stir in the fresh chopped parsley. Taste the sauce and adjust the seasoning with more salt and pepper if needed. Let the dish rest for a few minutes before serving to allow the flavors to meld.

Additional Tips for Instant Pot Success

Master your pressure cooker and perfect this recipe with these five essential tips.

1. Don’t Overcrowd the Pot When Searing: To get a proper brown crust on your chicken, it needs direct contact with the hot surface of the pot. If you dump all the chicken in at once, it will steam instead of sear. Work in two batches if necessary. The flavor you build in this step is well worth the extra few minutes.
2. Layer, Don’t Stir (Before Cooking): The order of ingredients matters in an Instant Pot. After deglazing, add your chicken and sauce base, but place the peppers and any other vegetables right on top. Don’t stir them down into the liquid. This keeps them elevated from the most intense heat at the bottom of the pot, preventing them from turning to mush.
3. Adjust Cook Time for Chicken Thighs: If you opt to use boneless, skinless chicken thighs, they are more forgiving than breasts but benefit from a slightly longer cook time to become fall-apart tender. Increase the pressure cooking time to 10 minutes instead of 8.
4. Embrace Flavor Variations: This recipe is a fantastic canvas for experimentation. For a Mexican-inspired twist, swap the oregano and basil for cumin and chili powder and add a can of black beans (rinsed) along with the peppers. For a bit of briny, Mediterranean flavor, add some Kalamata olives and a sprinkle of feta cheese at the end.
5. Master the Cornstarch Slurry: Always mix cornstarch with cold water before adding it to a hot liquid. If you add cornstarch directly to the hot sauce, it will clump up instantly and be impossible to dissolve. A smooth slurry ensures a smooth, perfectly thickened sauce every time.

Frequently Asked Questions (FAQ)

Here are answers to the most common questions about making this Instant Pot recipe.

1. I got the “BURN” notice on my Instant Pot! What went wrong?
The “BURN” notice is almost always caused by food being stuck to the bottom of the pot, preventing the liquid from circulating properly. The most likely culprit is that the pot wasn’t deglazed thoroughly after searing the chicken. Scrape every last browned bit off the bottom with your broth. Also, ensure you have enough thin liquid (at least ½ cup for a 6-quart pot) for the pot to come to pressure.

2. Can I use frozen chicken for this recipe?
Yes, you can use frozen chicken cubes in a pinch. You can skip the searing step and place the frozen cubes directly into the pot. You will need to increase the pressure cooking time to 12-15 minutes to ensure the chicken is cooked through. The final texture may be slightly less firm, but it will still be delicious.

3. My bell peppers are too soft/mushy. How can I fix this for next time?
This is a common issue. To ensure your peppers retain some texture, make sure you are cutting them into thicker strips (at least ½-inch wide). Most importantly, layer them on top of all the other ingredients and do not stir them in before cooking. A 5-minute natural release is perfect; a longer natural release can continue to cook and soften them.

4. Can I double this recipe in my 6-quart Instant Pot?
While you can double the ingredients, you may run into issues with the “Max Fill” line on a 6-quart pot. Doubling the recipe is better suited for an 8-quart Instant Pot. If you do attempt it in a 6-quart model, be very careful not to exceed the ⅔ full line, as the pot needs empty space to build pressure safely. The cooking time would remain the same.

5. How do I store and reheat leftovers?
This recipe is fantastic for leftovers! Store the cooled chicken and peppers in an airtight container in the refrigerator for up to 4 days. You can also freeze it for up to 3 months. To reheat, you can use the microwave or gently warm it in a saucepan on the stove. The sauce may thicken slightly upon refrigeration; you can add a splash of chicken broth or water to thin it out if needed.
