Description

Al dente fettuccine pasta is topped with tender chunks of chicken and a creamy Alfredo sauce made with mushrooms, tomatoes, and lots of cheese.

Ingredients

6 tablespoons butter, divided
6 skinless, boneless chicken breast halves - cut into cubes
4 cloves garlic, minced, divided
1 tablespoon Italian seasoning
1 pound fettuccini pasta
1 onion, diced
1 (8 ounce) package sliced mushrooms
1/3 cup all-purpose flour
1 tablespoon salt
3/4 teaspoon ground white pepper
3 cups milk
1 cup half-and-half
8 ounces shredded Colby-Monterey Jack cheese
3/4 cup grated Parmesan cheese
3 roma (plum) tomatoes, diced
1/2 cup sour cream

Directions

1 Gather all ingredients.
2 Melt 2 tablespoons butter in a large skillet over medium heat. Add chicken, 1/2 of the garlic, and Italian seasoning. Cook until chicken is no longer pink in the center and the juices run clear. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Remove from the skillet and set aside.
3 Fill a large pot with lightly salted water and bring to a rolling boil. Cook fettuccine at a boil until tender yet firm to the bite, 8 to 10 minutes. Drain.
4 Meanwhile, melt remaining 4 tablespoons butter in the skillet. Add onion, mushrooms, and remaining garlic; sauté until onion is transparent, about 5 minutes.
5 Stir in flour, salt, and pepper; cook for 2 minutes. Slowly add milk and half-and-half; cook and stir until smooth and creamy. Stir in both cheeses until melted.
6 Stir in chicken mixture, tomatoes, and sour cream. Serve over cooked fettuccini.
7 Enjoy!
