# What You'll Need:
→ Pasta
01 - 12 oz penne pasta
→ Chicken
02 - 1 lb boneless, skinless chicken breasts
03 - 1/2 tsp salt
04 - 1/4 tsp black pepper
05 - 1 tbsp olive oil
→ Sauce
06 - 2 tbsp unsalted butter
07 - 1 medium yellow onion, finely chopped
08 - 3 garlic cloves, minced
09 - 1/2 tsp red pepper flakes (optional)
10 - 14 oz canned crushed tomatoes
11 - 1/2 cup heavy cream
12 - 1/3 cup freshly grated parmesan cheese
13 - 1/2 cup fresh basil leaves, chopped
14 - Salt and black pepper, to taste
# Directions:
01 - Bring a large pot of salted water to a boil and cook the penne pasta until al dente. Drain, reserving 1/2 cup of pasta cooking water, then set pasta aside.
02 - While pasta cooks, season chicken breasts evenly with salt and black pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Add chicken and cook 5 to 6 minutes per side until golden and cooked through. Transfer to a plate and allow to rest for 5 minutes before slicing thinly.
04 - Reduce skillet heat to medium. Add butter and chopped onion, sautéing for 3 to 4 minutes until translucent. Add garlic and red pepper flakes, cooking 1 minute until fragrant.
05 - Stir in crushed tomatoes and let simmer for 5 minutes to develop flavor.
06 - Lower heat and stir in heavy cream. Simmer for 2 to 3 minutes until sauce slightly thickens.
07 - Mix in parmesan and half of the basil leaves, stirring until cheese melts. Season sauce with salt and black pepper to taste.
08 - Add sliced chicken and drained pasta to the sauce. Toss thoroughly to coat, adding reserved pasta water gradually to achieve a smooth consistency.
09 - Immediately plate the dish, garnishing with remaining basil and additional parmesan as desired.
