For the Cheesy Cajun Rotini
  • 1 lb rotini pasta or any short pasta
  • 6 tablespoons butter
  • 4 cloves garlic minced
  • 3 tablespoons all-purpose flour
  • 3 cups whole milk
  • 2 cups shredded sharp cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1 tablespoon Cajun seasoning
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 green onions thinly sliced, for garnish

Equipment

  • Large Pot
  • Large Skillet
  • Medium Saucepan
  • Spoon or Spatula
  • Whisk

Method
 

  1. Step 1: Get a big pot of salted water boiling. Add the rotini and cook according to package directions until al dente. Drain well and set aside.
  2. Step 2: While pasta cooks, toss cubed chicken breasts in a bowl with olive oil, 1 tablespoon Cajun seasoning, smoked paprika, ½ teaspoon salt, and ¼ teaspoon black pepper to coat.
  3. Step 3: Heat a large skillet over medium-high heat. Melt 2 tablespoons of the chicken butter. Add the seasoned chicken cubes and sear for about 6-8 minutes, stirring occasionally, until golden brown and cooked through. Transfer chicken to a plate and set aside.
  4. Step 4: In the same skillet, melt the remaining 2 tablespoons of the chicken butter over medium heat. Add the 4 cloves of minced garlic (from the chicken ingredients) and cook for about 1 minute, stirring constantly, until fragrant. Keep this garlic butter mixture and the skillet handy.
  5. Step 5: In a separate medium saucepan, melt the 6 tablespoons of butter (from the sauce ingredients) over medium heat. Add the 4 cloves of minced garlic (from the sauce ingredients) and sauté for about a minute until fragrant.
  6. Step 6: Sprinkle the flour over the butter and garlic in the saucepan. Whisk constantly for 1-2 minutes to cook out the raw flour taste and form a smooth, golden roux.
  7. Step 7: Gradually pour in the whole milk, a little at a time, while whisking constantly to keep the mixture smooth. Increase heat slightly and bring to a gentle simmer, whisking occasionally. Let it simmer for about 5-6 minutes until slightly thickened.
  8. Step 8: Turn the heat down to low. Stir in the shredded cheddar and mozzarella cheeses until fully melted and the sauce is smooth and creamy. Season the sauce with the tablespoon of Cajun spice (from the sauce ingredients), ½ teaspoon salt, and ¼ teaspoon black pepper. Taste and adjust seasoning.
  9. Step 9: Add the drained rotini pasta to the cheese sauce in the saucepan. Gently stir everything together until the pasta is evenly coated.
  10. Step 10: Add the cooked chicken cubes back into the skillet with the garlic butter made in Step 4. Give it a quick toss to coat the chicken.
  11. Step 11: Spoon portions of the creamy pasta into bowls. Top generously with the garlic butter Cajun chicken. Sprinkle with thinly sliced green onions for garnish. Serve warm.

Notes

Storage: Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop over low heat, adding a splash of milk or broth to loosen the sauce, or microwave individual portions, stirring halfway through.
Tips for Success: Cook pasta al dente. Whisk flour and butter for 1-2 minutes for a proper roux. Add milk gradually while whisking for a lump-free sauce. Keep cheese sauce on low heat after adding cheese to prevent separation. Always taste and adjust seasoning. You can cook the chicken and sauce ahead of time and store separately, reheating gently before combining with freshly cooked pasta.
Substitutions & Additions: Try shrimp or smoked sausage instead of chicken. Add chopped bell peppers, onions, or spinach for extra veggies. Use penne, farfalle, or other short pasta shapes. Experiment with different cheeses like Monterey Jack or Pepper Jack. Adjust spice level with Cajun seasoning or a pinch of cayenne.
