Notes & Substitutions

Instructions For Mississippi Chicken Spaghetti

Creamy Mississippi Chicken Spaghetti with Pepperoncini and Green Onions

Follow these easy steps to prepare your amazing Mississippi Chicken Spaghetti recipe. This simple process ensures a perfect, comforting meal every time.

  1. Gather all ingredients. This helps streamline the cooking process.
  2. Prepare Slow Cooker: Place the chicken breasts in the bottom of your slow cooker. This forms the base for our flavorful Mississippi chicken pasta.
  3. Season Chicken: Sprinkle the au jus and ranch seasoning mixes evenly over the chicken. These packets pack a huge flavor punch for this slow cooker chicken spaghetti.
  4. Add Flavor: Place 6 of the pepperoncini peppers on top of the chicken. Pour 1/4 cup of the pepperoncini brine from the jar over everything. This is key for the unique tangy flavor in this Mississippi Chicken Spaghetti recipe.
  5. Top with Butter: Lay the stick of butter on top of the chicken and peppers. The butter slowly melts, infusing richness throughout the dish.
  6. Slow Cook: Cover the slow cooker with its lid. Cook on High for 2 hours and 15 minutes. The chicken will become incredibly tender.
  7. Incorporate Creaminess: Uncover the slow cooker. Add the 8 ounces of cream cheese to the pot. Replace the lid and continue to cook while the pasta cooks, about 10 minutes, allowing the cream cheese to soften.
  8. Cook Pasta: Meanwhile, bring a large pot of salted water to a boil. Add the 1 pound of spaghetti and cook for 9 minutes, or until al dente. Reserve 1/2 cup of the starchy pasta water before draining the spaghetti.
  9. Shred Chicken: Carefully remove the cooked chicken from the slow cooker and shred it into bite-sized pieces using two forks. Remove the cooked peppers and chop them into smaller pieces. Chop the remaining 6 fresh pepperoncinis. Add all the shredded chicken and chopped peppers back to the slow cooker. Stir until the mixture is well combined and creamy. This is crucial for a smooth Mississippi Chicken Spaghetti recipe.
  10. Add Pasta & Cheese: Add the drained spaghetti, the reserved 1/2 cup pasta water, and 1 cup of the shredded Monterey Jack cheese to the slow cooker. Stir until all ingredients are well combined and the pasta is coated in the creamy sauce.
  11. Melt Cheese Topping: Top the mixture with the remaining shredded Monterey Jack cheese. Cover the slow cooker again and cook until the cheese is melted and bubbly, about 5 to 10 minutes.
  12. Serve: Spoon the delicious Mississippi Chicken Spaghetti recipe into bowls. Garnish generously with fresh sliced green onions for a pop of color and mild onion flavor. Enjoy!

Pro Tips & Troubleshooting

Make your slow cooker chicken spaghetti perfect every time with these helpful tips.

  • Perfectly Shredded Chicken: Use two forks to shred the chicken directly in the slow cooker for ease. For an even quicker method, use a hand mixer to shred the cooked chicken in the pot.
  • Achieving Creamy Sauce: Don’t skip reserving the pasta water! Its starch helps thicken the sauce and ensures a luscious, creamy texture for your creamy chicken pasta.
  • Adjusting Spice Level: For more heat, add extra pepperoncinis or a pinch of red pepper flakes. For less tang, reduce the amount of pepperoncini brine.
  • Preventing Dry Pasta: Cook your spaghetti al dente, as it will continue to absorb liquid in the slow cooker. If the dish seems too thick, add a splash more pasta water or chicken broth.
  • Faster Cooking Options: If you’re truly short on time, use pre-cooked rotisserie chicken. Just add it during the last 30 minutes of slow cooking to ensure it’s heated through.
  • Make Ahead Tips: You can cook the chicken mixture ahead of time. Refrigerate it, then reheat and combine with freshly cooked pasta and cheese when ready to serve this easy chicken spaghetti.

Serving, Storage, & Variations

This versatile Mississippi Chicken Spaghetti recipe is a crowd-pleaser that offers many possibilities.

Serving Suggestions

  • Pair this hearty creamy chicken pasta with a crisp green salad tossed in a light vinaigrette for a balanced meal.
  • Warm, crusty garlic bread is perfect for soaking up every last bit of the rich sauce.
  • Steamed vegetables like broccoli or green beans make a great, simple side dish.
  • Serve with a fresh baguette to scoop up the cheesy goodness.

Storage

  • Refrigerate: Store leftover Mississippi chicken pasta in an airtight container in the refrigerator for up to 3-4 days.
  • Freeze: For longer storage, freeze cooled leftovers in freezer-safe containers for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

Reheating

  • Microwave: Reheat individual portions in the microwave until warmed through, adding a splash of chicken broth or milk if the sauce is too thick.
  • Stovetop: Gently reheat larger portions in a pot over medium-low heat, stirring occasionally and adding a little broth to prevent drying.

Variations

  • Spicy Kick: Stir in a diced jalapeño with the chicken, or add a pinch of red pepper flakes for an extra fiery Mississippi chicken pasta.
  • Veggie Boost: Sauté sliced mushrooms, bell peppers, or spinach and stir them in with the cooked pasta for added nutrition and texture.
  • Different Proteins: This creamy chicken pasta is also fantastic with shredded pork or even ground turkey for a different flavor profile.
  • Baked Version: After combining the chicken, pasta, and sauce, transfer the mixture to a 9×13 inch casserole dish. Top with extra cheese and bake at 375°F (190°C) for 20-25 minutes, or until bubbly and golden.

Common Mistakes to Avoid

  • Overcooking the spaghetti: Always cook it al dente; it will continue to soften in the slow cooker.
  • Not reserving pasta water: This starchy water is crucial for creating a silky, creamy sauce.
  • Forgetting the pepperoncini brine: The brine is essential for the signature tangy flavor of this dish.
