Step-by-Step Instructions
Step 1 – Cook the Spaghetti
Begin by cooking the spaghetti according to the package directions in a pot of salted boiling water until al dente.
Visual cue: The pasta should be firm to the bite but cooked through. Drain and set aside.
Step 2 – Sear the Chicken
Season the chicken pieces with Cajun seasoning and smoked paprika. In a large skillet, heat olive oil over medium-high heat and add the chicken. Cook until browned and cooked through, about 6–8 minutes.
Visual cue: The chicken should have a golden exterior and should be cooked completely.
Step 3 – Make the Roux
Remove the chicken from the skillet and set aside. In the same skillet, melt butter over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
Visual cue: The garlic should become soft but not browned.
Step 4 – Create the Sauce
Sprinkle in the flour and whisk continuously for 1–2 minutes to form a roux. Gradually whisk in the milk and chicken broth, stirring constantly to avoid lumps. Bring to a gentle simmer.
Visual cue: The mixture should thicken slightly and be smooth without lumps.
Step 5 – Add Cheeses
Add the cream cheese and 1 cup of mozzarella to the sauce, stirring until melted and smooth. Stir in the Parmesan cheese and season with salt, pepper, and red pepper flakes if using.
Visual cue: The sauce should be creamy and velvety, with all cheeses fully incorporated.
Step 6 – Reintroduce Chicken
Add the cooked chicken back into the sauce and simmer for 2–3 minutes to heat through.
Visual cue: The chicken should be evenly coated with the sauce and warm.
Step 7 – Combine with Spaghetti
Add the cooked spaghetti to the skillet and toss to coat in the sauce.
Visual cue: Each strand of spaghetti should be well-coated with the creamy sauce.
Step 8 – Melt Remaining Cheese
Sprinkle the remaining 1 cup of mozzarella on top, cover, and let sit for 2–3 minutes until the cheese melts.
Visual cue: The cheese should be bubbly and melted, blending beautifully with the spaghetti.
Pro Tips for Success
- Control the Heat: Keep the heat medium to ensure the butter does not burn when making the roux.
- Texture Check: Avoid overcooking the spaghetti; it should be al dente for best texture.
- Season Smart: Taste the sauce before serving and adjust the seasoning as needed for a well-balanced flavor.
- Avoid Lumps: Whisk vigorously when adding liquid to the roux to keep the sauce smooth.
- Don’t Skip the Resting: Letting the dish sit after adding mozzarella allows the cheese to melt properly and provides a richer texture.
Flavor Variations
- Spicy Version: Add more Cajun seasoning or a dash of hot sauce for an extra kick.
- Cheesy Version: Increase the amount of mozzarella or consider adding another cheese like cheddar for varied flavors.
- Veggie Boost: Stir in sautéed bell peppers, zucchini, or spinach to incorporate more vegetables.
- Protein Swap: Substitute the chicken with shrimp or cooked sausage for a different protein profile.
- Herb-Infused: Add fresh herbs like basil or parsley for a pop of freshness.
Serving Suggestions
- Pair with a simple green salad dressed with vinaigrette for a refreshing side.
- Serve with garlic bread to scoop up the creamy sauce.
- Offer a sprinkle of fresh parsley or extra Parmesan on top for garnish.
- Enjoy as a communal dish, allowing everyone to serve themselves directly from the skillet.
- This dish is also fantastic reheated for lunch the next day!
