# What You 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
# Steps:
01 - Boil penne pasta in a large pot of salted water until al dente. Drain, reserving 1/2 cup of the cooking water, then set pasta aside.
02 - Season chicken breasts evenly with salt and black pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Sear chicken breasts for 5-6 minutes per side or until golden brown and cooked through. Remove and let rest for 5 minutes, then slice thinly.
04 - Reduce skillet heat to medium. Add butter and chopped onion; sauté for 3-4 minutes until translucent. Stir in garlic and red pepper flakes; cook for 1 minute until fragrant.
05 - Add crushed tomatoes to the skillet and simmer for 5 minutes to develop flavors.
06 - Lower heat and stir in heavy cream. Simmer gently for 2-3 minutes until sauce slightly thickens.
07 - Stir in parmesan cheese and half of the chopped basil until cheese melts. Season sauce with salt and pepper to taste.
08 - Add sliced chicken and cooked pasta to the sauce. Toss gently to coat evenly, adding reserved pasta water as necessary to achieve a silky texture.
09 - Plate immediately, garnishing with remaining basil and additional parmesan if desired.
