It’s a vibrant, crowd-pleasing meal that delivers all the gooey, melted cheese satisfaction of a baked casserole with the effortless cleanup of a one-pot wonder.

🥗 Ingredients

The Base

  • 1 tablespoon Olive Oil (or avocado oil)
  • 1.5 pounds Chicken Breast (boneless, skinless, cut into 1-inch cubes)
  • 1 Yellow Onion (medium-sized, finely diced)
  • 3 cloves Garlic (minced)

Pasta and Liquids

  • 12 ounces Rotini or Penne Pasta (dry, uncooked)
  • 15 ounces Red Enchilada Sauce (mild or medium heat)
  • 2.5 cups Chicken Broth (low-sodium)
  • 4 ounces Diced Green Chiles (one small can)
  • 1 cup Black Beans (rinsed and drained)
  • 1/2 cup Frozen Corn

Seasoning and Finishers

  • 1 teaspoon Chili Powder
  • 1 teaspoon Ground Cumin
  • 1/2 teaspoon Smoked Paprika
  • 2 cups Mexican Blend Cheese (shredded)
  • 2 ounces Cream Cheese (cubed, at room temperature)

For Garnish

  • 1/4 cup Fresh Cilantro (chopped)
  • 2 pieces Green Onions (sliced thin)
  • 1/2 cup Sour Cream (for dolloping)

👨‍🍳 Instructions

  1. 1

    Turn the Instant Pot to 'Sauté' mode and add the olive oil. Once hot, add the diced chicken and cook for 3-4 minutes until lightly browned on the outside.

  2. 2

    Add the diced onion to the pot with the chicken. Sauté for another 3 minutes until the onion becomes translucent and soft.

  3. 3

    Stir in the minced garlic, chili powder, cumin, and smoked paprika. Toast the spices for about 30 seconds until fragrant, being careful not to burn the garlic.

  4. 4

    Pour in about 1/4 cup of the chicken broth and use a wooden spoon to scrape the bottom of the pot (deglazing). This ensures no brown bits are stuck, which prevents the 'Burn' warning.

  5. 5

    Add the dry pasta, the remaining chicken broth, the red enchilada sauce, and the green chiles. Do NOT stir; simply press the pasta down with a spoon to ensure it is mostly submerged in liquid.

  6. 6

    Layer the black beans and corn on top of the pasta. Again, do not stir the mixture together.

  7. 7

    Secure the Instant Pot lid and set the valve to the 'Sealing' position. Cancel the Sauté mode.

  8. 8

    Select 'Manual' or 'Pressure Cook' on High Pressure and set the timer for 5 minutes. (Rule of thumb: half the time listed on the pasta box minus 1 minute).

  9. 9

    Once the cooking time is complete, perform a 'Quick Release' by carefully turning the valve to the 'Venting' position to release the steam.

  10. 10

    Open the lid and stir the mixture. It may look a bit liquidy at first, but it will thicken as it sits.

  11. 11

    Add the cubed cream cheese and 1 cup of the shredded Mexican blend cheese. Stir gently until the cream cheese is fully melted and the sauce is velvety.

  12. 12

    Sprinkle the remaining 1 cup of cheese over the top. Place the lid back on for 2-3 minutes (with the power off) to allow the residual heat to melt the cheese topping.

  13. 13

    Garnish with fresh cilantro, green onions, and a dollop of sour cream before serving directly from the pot.

💡 Chef's Tips

Always deglaze the bottom of the pot thoroughly after sautéing to avoid the 'Burn' error. For a spicier kick, add a chopped jalapeño with the onions or use a 'Hot' rated enchilada sauce. If using gluten-free pasta, reduce the pressure cooking time by 1-2 minutes to prevent the noodles from becoming mushy. Use freshly grated cheese from a block if possible; it melts much smoother than pre-shredded bags which contain anti-clumping starches. If the sauce is too thin after pressure cooking, let it sit for 5 minutes with the lid off; the pasta will continue to absorb the excess moisture.

🍽️ Serving Suggestions

Serve with a side of warm flour tortillas or crispy tortilla chips for scooping. Pair with a crisp, cold Mexican lager or a fresh lime margarita to cut through the richness. A simple side salad with avocado and a lime-cilantro vinaigrette provides a refreshing contrast. Top with pickled red onions for a bright, acidic pop of flavor. Add a side of Mexican street corn (Elote) to make it a full festive feast.
