Instant Pot Chicken Fajita Pasta
Description
Creamy, cheesy, one-pot Instant Pot chicken fajita pasta with rotini, peppers, salsa, and smoky Tex-Mex spices. Ready in 30 minutes — perfect for busy weeknights with no draining required.
Ingredients
For the pasta:
- 1 tablespoon olive oil
- 2 boneless, skinless chicken breasts, (about 1 lb), diced into 1-inch pieces
- 1 medium red onion, diced
- 2 tablespoons minced garlic
- 1 cup salsa, medium heat
- 2 tablespoons fajita seasoning, homemade or store-bought
- ½ teaspoon salt, skip if your seasoning is salted
- 3 cups chicken broth
- 3 cups rotini pasta, uncooked
- 1 red bell pepper, diced
- 1 green bell pepper, diced
- ⅓ cup heavy cream
- 1 cup shredded Mexican blend or sharp cheddar cheese, freshly shredded
For serving (optional):
- Fresh cilantro, chopped
- Lime wedges
- avocado, Diced
- Sour cream
- Pico de gallo
- Crushed tortilla chips
- Pickled jalapeños
Instructions
- Build the base. Add the olive oil, diced chicken, red onion, garlic, salsa, fajita seasoning, salt, and chicken broth to the Instant Pot. Stir well to make sure nothing is stuck to the bottom of the pot — this prevents a burn notice.
- Layer the pasta on top. Pour the rotini evenly over the liquid and press it down gently so the broth just covers it. Do not stir. If the pasta isn't fully submerged, add 1–2 tablespoons of water.
- Pressure cook. Lock the lid in place and set the valve to sealing. Cook on HIGH PRESSURE for 4 minutes. The pot will take 8–10 minutes to come to pressure before counting down.
- Quick release. When the timer beeps, carefully move the valve to venting for a quick pressure release. Wait until the float pin drops, then open the lid.
- Add peppers, cream, and cheese. Stir in the diced bell peppers, then the heavy cream, then the shredded cheese. Stir until the cheese is melted and the sauce coats the pasta.
- Rest. Place the lid back on (no need to pressurize) and let everything sit for 3–5 minutes. The residual heat softens the peppers just enough while the sauce finishes thickening.
- Serve. Garnish with fresh cilantro, a squeeze of lime, and your favorite toppings. Serve hot.
Equipment
- 6-quart Instant Pot or electric pressure cooker
- Wooden Spoon
- Measuring Cups and Spoons
- Cutting board and chef's knife
Notes
- Pasta on top, never stirred in. Stirring pasta into the liquid is the #1 cause of burn notices in Instant Pot pasta recipes. Layer it, don't mix it.
- Pepper texture. Adding peppers at the end keeps them crisp-tender. For fully soft peppers, sauté them at the start, set aside, and stir them back in at the end. Pressure cooking peppers turns them mushy.
- Don't use frozen chicken. The pasta will overcook waiting for frozen chicken to finish. Thaw it in the fridge overnight first.
- Heat level. Comes down to your salsa and fajita seasoning. Heavy cream tames spice noticeably, so don't be afraid of medium or even hot salsa.
- Cream substitutes. Half-and-half works (sauce will be thinner). 4 ounces of cream cheese also works (sauce will be thicker and tangier). Avoid milk alone — it can curdle.
- Cheese matters. Freshly shred from a block. Pre-shredded cheese has anti-caking starches that keep it from melting smoothly into the sauce.
- Doubling the recipe. Double every ingredient and keep the 4-minute cook time the same. Don't fill the pot past the max fill line — pasta expands.
- Make it vegetarian. Swap the chicken for one drained, rinsed can of black beans (added at the end with the peppers) and use vegetable broth.
- Storage. Refrigerate up to 4 days in an airtight container. Reheat with a splash of broth or milk to loosen the sauce.
- Freezing. Freeze the chicken-and-sauce base WITHOUT the cream and cheese for up to 2 months. Add fresh cream and cheese when reheating.
