Ingredients and Preparation

Here’s a detailed breakdown of everything you’ll need to make this creamy, flavorful pasta dish:

Ingredients

• 3 ½ cups (828ml) chicken broth or chicken stock
  • This adds flavor to the pasta as it cooks. You can substitute vegetable broth if you’re out of chicken stock.
• 1 pound (454g) penne pasta
  • Penne holds its shape well under pressure cooking, but you can also use rigatoni or ziti. For a healthier option, try whole wheat or chickpea pasta.
• 1 red onion, finely diced
  • Red onion adds a mild sweetness and color. Yellow onions work as a substitute.
• 1 tablespoon fajita seasoning or taco seasoning
  • Use store-bought seasoning or make your own blend of chili powder, paprika, cumin, garlic powder, and onion powder.
• 1 teaspoon dried oregano
  • This herb brings out earthy undertones. Italian seasoning can also work in a pinch.
• Salt, to taste
  • Adjust according to your preference. Remember, broth and seasoning mixes can add saltiness.
• 1 pound (454g) boneless, skinless chicken breasts, diced
  • Swap with boneless chicken thighs or cooked, shredded rotisserie chicken for convenience.
• ¾ cup salsa
  • This adds tangy, spicy flavors. Choose mild, medium, or hot based on your preference.
• 3 bell peppers, chopped (use different colors)
  • A mix of red, yellow, and green peppers adds vibrant color and crunch.
• ½ cup (242g) half and half or heavy cream
  • For a dairy-free option, use coconut cream or almond milk.
• ¾ cup (62g) grated cheese
  • Cheddar, Monterey Jack, or a Mexican blend work perfectly.

Step-by-Step Instructions

Cooking in an Instant Pot can be intimidating at first, but this recipe makes it foolproof. Here’s how to make it:

1. Prepare the Ingredients
   • Dice the chicken breasts into bite-sized pieces. Chop the bell peppers and finely dice the red onion. Measure out all your ingredients before starting to streamline the process.
2. Add Ingredients to the Instant Pot
   • Pour the chicken broth into the pot. Add the pasta, red onion, fajita seasoning, oregano, and salt. Lay the diced chicken on top. Do not stir—this prevents ingredients from sticking to the bottom.
3. Add the Salsa
   • Spread the salsa evenly over the top of the chicken and pasta. Again, avoid stirring.
4. Pressure Cook
   • Secure the Instant Pot lid and set the valve to “Sealing.” Select the high-pressure “Pressure Cook” or “Manual” function and set the timer for 4 minutes.
5. Quick Release
   • Once the cooking cycle is complete, perform a quick pressure release by carefully turning the valve to “Venting.” Open the lid once the pressure has fully released.
6. Add Final Ingredients
   • Stir in the chopped bell peppers, half and half, and grated cheese. Cover the pot with the lid (without sealing) and let the residual heat soften the peppers and melt the cheese, about 7 minutes.
7. Serve and Enjoy
   • Give everything a good stir to combine. Garnish with fresh cilantro, lime wedges, or extra cheese if desired. Serve immediately.

Beginner Tips and Notes

This recipe is beginner-friendly, but a few extra tips can make your cooking experience even smoother:

Troubleshooting

• If the pasta sticks to the pot: Always ensure the pasta is fully submerged in the broth before cooking. Use a wooden spoon to press it down gently.
• If the chicken browns too quickly: Cut the chicken into uniform pieces to ensure even cooking. You can also sauté the chicken in the Instant Pot on “Sauté” mode before adding the other ingredients.
• If the vegetables are too crunchy: Let the dish rest with the lid on for a few more minutes to soften the peppers.

Efficiency Tips

• Prep in advance: Chop onions and bell peppers ahead of time and store them in the fridge.
• Freeze leftovers: Store leftover onions and peppers in the freezer for up to 2 months. Add them directly to the Instant Pot without thawing.
• Save time with rotisserie chicken: Use pre-cooked chicken to skip the dicing step.

Substitution Ideas

• For a vegetarian version: Replace chicken with tofu or omit it altogether. Use vegetable broth instead of chicken broth.
• For added spice: Add diced jalapeños or a splash of hot sauce.
• For dairy-free: Use coconut cream or almond milk instead of heavy cream and nutritional yeast instead of cheese.

Serving Suggestions

Pair your Instant Pot Chicken Fajita Pasta with complementary sides to create a complete meal:

• Fresh salad: A simple green salad with avocado, cucumber, and lime vinaigrette pairs beautifully with the creamy pasta.
• Garlic bread: Serve warm, crusty garlic bread for a satisfying contrast in texture.
• Salsa and chips: Add an extra element of fun with tortilla chips and salsa or guacamole.

Leftovers

• Store leftovers in an airtight container in the fridge for up to 4 days.
• Freeze portions for up to 3 months. Thaw in the fridge overnight and reheat gently on the stove or in the microwave.
