Ingredients
- 2 medium (about 1 lb), sliced into 1/2-inch strips chicken breasts
- 2 tbsp Cajun seasoning
- 12 oz penne pasta
- 4, minced garlic cloves
- 4 cups chicken broth
- 1 cup heavy cream
- 1 cup, grated parmesan cheese
- 3 cups baby spinach
- 2 tbsp olive oil
- 1 tsp, divided salt
- 1/2 tsp, divided black pepper
Instructions
- Step 1: Heat 2 tbsp olive oil in a large deep skillet or Dutch oven over medium-high heat. Toss 2 medium sliced chicken breasts with 2 tbsp Cajun seasoning, then add to skillet. Cook for 5-6 minutes, stirring occasionally, until chicken is cooked through and edges are slightly charred. Remove chicken and set aside.
- Step 2: In the same skillet, add 4 minced garlic cloves and sauté over medium heat for 30 seconds until fragrant.
- Step 3: Add 12 oz dry penne pasta and 4 cups chicken broth. Bring to a boil, then reduce heat to medium-low and simmer uncovered for 12 minutes, stirring occasionally until pasta is tender and most of the broth is absorbed.
- Step 4: Stir in 1 cup heavy cream, 1 cup grated parmesan cheese, and 3 cups baby spinach. Cook for 2-3 minutes until spinach wilts and sauce thickens slightly.
- Step 5: Return cooked Cajun chicken to the skillet. Season with 1/2 tsp salt and 1/4 tsp black pepper, stirring to combine. Cook for 1 more minute to heat through before serving.
