Rich creamy lemon basil sauce with sauteed chicken tossed with pasta.
Start by boiling water in a large pot. Add a generous amount of salt to the pot of water. This will help to season the pasta. Cook pasta according to package instructions. Drain.
While water is heating up, in a large skillet, heat butter and olive oil over medium heat. Add onion and saute for 5-6 minutes. Turn up the heat to medium-high and add chicken breast. Saute for 7-8 minutes. Add garlic and saute for 1 minute. Garlic can easily burn so watch it carefully. Season with salt, pepper, and red pepper flakes.
Add chicken broth and heavy cream or half-n-half. Let simmer for 5 minutes. Stir in lemon juice and lemon zest. If you want more lemon flavor, add more lemon zest. Taste sauce and add more salt, if necessary.
