To a large pot, add water and bring it to a boil. Once boiling, add the rotini and cook according to the package directions. After cooking, drain the pasta and return it to the pot.
While the pasta cooks, take out a large skillet. Drizzle in 2 tablespoons of olive oil and heat it over medium-high. Once hot, add the diced chicken and season it with lemon pepper and kosher salt. Cook for about 5 minutes, stirring frequently.
When the chicken is nearly done, add the minced garlic to the skillet. Cook for one minute, stirring constantly until fragrant.
Next, pour in the lemon juice and toss in half of the spinach. Stir everything together and cover the skillet with a lid for about 2 minutes.
After about 2 minutes, add the remaining half of the spinach and stir it in. Cook until all the spinach is wilted down.
Now, it’s time to combine everything! Add the chicken and spinach mixture, along with all the cooking juices, to the pot with the cooked pasta. Toss everything together until well combined.
Finally, add the remaining 2 tablespoons of olive oil and the minced basil. Give it one last good stir to mix everything together.
Serve your Lemon Pepper Chicken Pasta hot, and enjoy immediately. This dish is best enjoyed fresh, but it will keep in an airtight container in the fridge for up to 5 days if you have leftovers.
