Begin by flattening the chicken breasts to an even thickness. Season both sides with salt and crushed red pepper.
In a large skillet, melt the butter over medium heat. Add the chicken and cook for about 6-7 minutes on each side.
Remove the chicken from the skillet and set aside. In the same skillet, add the oil from sun-dried tomatoes and sauté the garlic for about 30 seconds.
Sprinkle the flour over the garlic and stir to create a roux. Gradually whisk in chicken broth, then add heavy cream, sun-dried tomatoes, thyme, and salt.
Return the chicken to the skillet and simmer in the sauce for about 5 minutes.
Meanwhile, cook the pasta according to package instructions. Drain and set aside.
In the last minutes of cooking, stir in the cooked peas.
To serve, plate the pasta and top with chicken and sun-dried tomato sauce. Enjoy!
