In a large pot, boil water and cook linguine (al dente) as directed on package.

In a separate saucepan, heat olive oil over medium heat. Add the chicken sausage and cook, breaking it apart. Add the garlic and cook another 2 minutes.

When the sausage is fully cooked, add the spinach, artichoke hearts, salt, and pepper.

In a measuring cup, whisk together the chicken broth and powdered heavy cream. Add the mixture to the saucepan and bring to a boil, stirring occasionally.

Sprinkle flour over sauce and incorporate. Stir until sauce slightly thickens.

Once linguine is cooked, drain and add to the saucepan. Toss pasta to coat with sauce.

To serve, sprinkle with red pepper flakes and parmesan cheese.
