Cook the Pasta: Bring a large pot of generously salted water to a rolling boil. Add the penne pasta and cook according to the package directions until al dente, typically around 9-11 minutes. Once cooked, drain the pasta and set it aside, reserving about 1/2 cup of the pasta water.
Sauté the Chicken: In a spacious skillet over medium heat, add the olive oil and allow it to warm. Introduce the cubed chicken to the skillet, seasoning it with salt, pepper, and red pepper flakes if desired. Sauté the chicken, stirring occasionally, until it is golden brown and fully cooked through, approximately 5-7 minutes. Once done, remove the chicken from the skillet and place it on a plate to rest.
Prepare the Sauce: In the same skillet, add the minced garlic and cook for about 30 seconds until it becomes fragrant, stirring continuously to avoid burning. Next, pour in the crushed tomatoes, stirring to combine, then bring the mixture to a gentle simmer.
Add Cream and Seasonings: Once simmering, carefully stir in the heavy cream, dried oregano, and sugar. Let the sauce simmer for an additional 5 minutes, stirring occasionally to enhance the flavors and allow it to thicken slightly.
Combine Ingredients: Return the sautéed chicken to the skillet with the sauce. Then add the drained penne pasta as well as the grated Parmesan cheese. Toss everything together gently until well combined and the pasta is evenly coated with the sauce. If the sauce appears too thick, add a splash of the reserved pasta water to achieve your desired consistency.
Garnish and Serve: Remove the skillet from heat and fold in the fresh chopped basil. Taste and adjust seasoning with additional salt and pepper if needed, ensuring the flavors are just right.
Notes
Serve with additional grated Parmesan and fresh basil for garnish.
