One-Pot Chicken Fajita Pasta


  • Author: OliviaBennett

Description

Born from a fridge clean-out and a dinner promise I had no idea how to keep, this dish became an instant classic in my tiny college kitchen. Today, it’s a weeknight regular—full of sizzling fajita flavors, tender chicken, and creamy pasta—all made in one pot with zero stress. Gather around the stove and get ready for second helpings.


Ingredients

Scale
  • 3 tbsp neutral oil (avocado or grapeseed)

  • 3 chicken breasts, sliced thin

  • 1 red, 1 green, 1 yellow bell pepper, sliced

  • 1 yellow onion, sliced

  • 1 tsp kosher salt + 1 tsp black pepper

  • 1 tbsp each: chili powder, cumin, garlic powder

  • 5 cups whole milk (or unsweetened oat milk)

  • 4 cups penne pasta

  • 1 cup shredded pepper jack cheese


Instructions

  • Heat oil in a large pot over medium-high. Sear chicken (5–6 mins), season, then set aside.

  • Sauté peppers and onions (4–5 mins). Stir in spices for 30 seconds.

  • Return chicken. Add milk and bring to a light simmer.

  • Stir in pasta. Cook uncovered 12–15 mins, stirring often, until al dente.

  • Turn off heat, stir in cheese until melted. Taste and adjust seasoning.

Notes

  • Stir pasta often to prevent sticking.

  • Warm milk first to avoid curdling.

  • Slice peppers evenly for perfect texture.

  • Let sauce thicken off-heat—it’ll become creamier as it cools.
