How to Make One Pot Chicken Fajita Pasta: Step-by-Step

1. Sear the Chicken

Heat 1 tablespoon of olive oil in a large skillet or Dutch oven over medium-high heat. Add the sliced chicken and cook for 4–5 minutes, stirring occasionally, until browned and cooked through. Remove the chicken from the pan and set aside.

2. Sauté the Veggies

In the same pot, add the remaining tablespoon of olive oil. Toss in the sliced bell peppers, onion, and garlic. Sauté for 4–5 minutes until the veggies are softened and slightly caramelized, but still have a bit of bite.

3. Season and Add Base Ingredients

Sprinkle the fajita seasoning over the sautéed vegetables and stir to coat everything evenly. Return the cooked chicken to the pot. Add the Rotel tomatoes and pour in the chicken broth. Stir well to combine.

4. Add Pasta and Cook

Bring the mixture to a gentle boil, then stir in the uncooked pasta. Reduce the heat to medium-low, cover the pot, and simmer for 12–15 minutes, stirring occasionally to prevent sticking. Cook until the pasta is al dente and most of the liquid has been absorbed.

5. Stir in the Cream Cheese and Cheddar

Once the pasta is cooked and the liquid has thickened slightly, add in the cubed cream cheese. Stir continuously until the cream cheese melts into the sauce. Then, sprinkle in the shredded cheddar cheese and stir until melted and smooth.

6. Garnish and Serve

Remove from heat and let the pasta sit for 5 minutes to thicken further. Garnish with fresh chopped cilantro, if desired, and serve hot.

Frequently Asked Questions

Can I use pre-cooked chicken?

What’s the best pasta for this dish?

Short pasta like penne, rotini, or rigatoni works best because they hold the sauce well.
