  7. Add the cooked spaghetti to the skillet, tossing to coat the pasta evenly with that luscious sauce.
  8. Serve hot, garnished with a sprinkle of chopped fresh parsley for a touch of brightness.

Substitutions & Additions

If you want to get creative with this recipe, here are some ideas:

  • Swap out the chicken for shrimp or even tofu for a different protein option.
  • Use half-and-half instead of heavy cream for a lighter sauce.
  • Add vegetables like spinach or sun-dried tomatoes for extra flavor and nutrition.
  • For a spicy kick, toss in some red pepper flakes or a splash of hot sauce.

Tips for Success

Here are a few tips to ensure your dish turns out perfectly:

  • Don’t overcook the chicken to prevent it from becoming dry. Cook just until it’s no longer pink.
  • Make sure to stir the sauce frequently to avoid any sticking or burning.
  • You can prep the chicken and sauce ahead of time and just combine it with the pasta when you’re ready to eat.

How to Store Garlic Butter Chicken Spaghetti with Creamy Roasted Red Pepper Sauce

If you have leftovers (which is rare because it’s so good), store them in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or on the stovetop, adding a splash of cream or water if the sauce thickens too much.

FAQs

  • Can I use whole wheat spaghetti? Absolutely! Whole wheat spaghetti will add a nice nutty flavor and is a healthier option.
  • Can this be made vegetarian? Yes! Simply replace the chicken with your favorite vegetables or plant-based protein.
