Equipment

  • A Large, Deep Skillet or Dutch Oven (12-inch or 5-Quart)
  • Sharp Knife
  • Cutting Board

Ingredients
  

For the Sizzling Fajita Base

  • 1.5 lbs boneless skinless chicken thighs, cut into bite-sized pieces
  • 1 tbsp. olive oil or avocado oil
  • 1 large yellow onion sliced
  • 2 bell peppers mix of red and green, sliced
  • 3-4 cloves garlic minced

For the From-Scratch Fajita Seasoning

  • 1 tbsp. chili powder
  • 2 tsp cumin
  • 1 tsp smoked paprika
  • 1 tsp dried oregano
  • 0.5 tsp onion powder
  • 0.25 tsp cayenne pepper or more, to taste
  • 1 tsp salt
  • 0.5 tsp black pepper

For the Creamy One-Pan Sauce

  • 10 oz. uncooked penne pasta
  • 3 cups low-sodium chicken broth
  • 1 cup heavy cream
  • 8 oz. Monterey Jack or Colby Jack blend shredded from a block
  • For Finishing & Topping
  • 0.5 cup fresh cilantro chopped
  • 1 lime juiced

Instructions
 

  • Pat chicken dry and place in a medium bowl. In a separate small bowl, whisk together all fajita seasoning spices. Toss the chicken with about two-thirds of the seasoning blend.
  • Heat olive oil in a large, deep skillet over medium-high heat until shimmering. Add chicken in a single layer and sear for 3-4 minutes per side until a deep golden-brown crust forms. The chicken will not be cooked through. Transfer to a clean plate.
  • In the same pan, add sliced onions and bell peppers. Sauté, stirring occasionally, for 5-7 minutes until softened with charred edges.
  • Make a well in the center of the veggies and add the minced garlic. Cook for 30-60 seconds until aromatic. Add the remaining third of the fajita seasoning and stir for 30 seconds to toast the spices. Transfer veggies to the plate with the chicken.
  • Pour the chicken broth into the empty skillet, scraping up all the browned bits from the bottom of the pan as it comes to a simmer.
  • Bring broth to a full simmer, then stir in the uncooked penne. Reduce heat to maintain a lively simmer. Cook, stirring frequently, until pasta is just al dente (check your package instructions, and start tasting 2 minutes before the time is up). Most of the broth will be absorbed.
  • Turn the heat down to LOW. Pour in the heavy cream and stir gently to combine.
  • Turn the heat OFF completely. Immediately add the shredded cheese, stirring constantly until it melts into a smooth, velvety sauce.
  • Return the chicken, veggies, and any accumulated juices to the skillet. Stir until everything is coated and warmed through.
  • Finish by stirring in the fresh lime juice and chopped cilantro. Serve immediately.

Notes

Kate's Expert Tips:
  • Perfect Flavor: For best results, use the homemade seasoning blend. The smoked paprika is key! If using a store-bought (1 oz) packet, add your own pinch of smoked paprika to boost the flavor.
  • Avoid Sticky Pasta: Be sure to scrape the pan well when you add the broth, and stir the pasta every couple of minutes as it cooks in the broth.
  • Silky Smooth Sauce: This is critical. Turn the heat to LOW before adding the cream, and turn it OFF before stirring in the cheese. The residual heat is plenty.
  • Emergency Fix: If your sauce separates, remove it from the heat. Whisk 1 tsp cornstarch with 2 tsp cold water, then slowly whisk that slurry into your sauce to help bring it back together.
  • Recommended Toppings: A dollop of sour cream or Greek yogurt, sliced avocado, crumbled cotija cheese, extra fresh cilantro and lime wedges, pickled jalapeños, and crushed tortilla chips.
