Prep the Ingredients – Cut the chicken thigh into small, bite-sized pieces. Mince the garlic and onion.
Season the chicken – In a small bowl, combine the chicken with paprika, oregano, salt, and pepper. Mix together thoroughly.
Cook the pasta – In a pot of salted boiling water, cook your pasta according to the time on the package directions, subtracting a minute (we will finish the pasta in sauce).
Cook the chicken – Head a stainless steel pan to medium-high heat. Spray with cooking spray and add the chicken pieces in a single layer on the pan. Cook for about 3-4 minutes each side.
Add the aromatics – After you turn the chicken pieces to the second side, add the chopped garlic, onion, and chili. Cook for about 1 minute or until fragrant, being sure to stir the ingredients to prevent the ingredients from burning.
Simmer the canned tomatoes – Add the canned tomatoes to the pan and bring the sauce to a simmer. Let cook for about 10 minutes or until the tomatoes have been cooked down so that they are easily burst with a wooden spoon.
Add the pasta and adjust the sauce – Save the pasta water before straining the pasta. Add the pasta into the sauce and mix thoroughly, adjusting the sauce with pasta water as needed. Add in the cheese and sugar and mix thoroughly.
Garnish and serve – Plate the dish and garnish with chopped parsley, more red pepper flakes, and parmesan cheese. Serve and enjoy your delicious chicken arrabiata!
