Step-by-Step Instructions

1. Prepare Your Ingredients

  • Slice green and red bell peppers into thin strips.
  • Cut red onion in half and slice one half into thin wedges.
  • Dice Roma tomatoes into small cubes.
  • Cube the chicken breasts into bite-sized pieces.

2. Cook the Fettuccine

Boil a large pot of salted water. Add fettuccine and cook according to package directions until al dente—about 8–10 minutes. Drain and set aside, reserving a bit of pasta water.

3. Season and Sear the Chicken

  • Sprinkle 1½ teaspoons Cajun seasoning (or more for extra heat) over all the chicken cubes and toss thoroughly.
  • Heat 1 tablespoon butter and 1 tablespoon olive oil in a heavy skillet over high heat.
  • Add half the chicken in a single layer—do not stir right away! Allow it to brown undisturbed for about 1 minute.
  • Flip chicken pieces and cook another minute, then remove to a clean plate. Repeat with second batch, adding oil/butter as needed.

4. Sauté the Vegetables

  • With the skillet still on high, add the rest of the butter and olive oil.
  • Once hot, add the minced garlic, bell pepper strips, and red onion. Sprinkle over the remaining Cajun seasoning, plus salt if necessary.
  • Sauté quickly, stirring, aiming to “blacken” some of the veggies for smoky flavor—about 1 minute.
  • Add the diced tomatoes and sauté for just 30 seconds.
  • Remove the sautéed vegetables from the skillet and set aside.

5. Build the Creamy Cajun Sauce

  1. Deglaze the still-hot pan by pouring in chicken broth and white wine. Scrape up all the browned bits (these add depth!) and simmer on high 3–5 minutes.
  2. Reduce heat to medium-low.
  3. Pour in the heavy cream, whisking constantly until the sauce thickens slightly—this takes another few minutes.
  4. Taste and adjust: Add more black pepper, cayenne, or salt as needed for your preferred spice level.

6. Combine and Serve

  • Return the cooked chicken and vegetables to the sauce, along with the drained fettuccine. Toss gently to combine and coat every noodle with that creamy, spicy sauce.
  • Serve immediately, garnished with a generous handful of freshly chopped parsley.

Tips and Tricks for Success

  • Don’t overcook the pasta. Al dente noodles hold up best, especially once mixed into the creamy sauce.
  • Use high heat for searing. Browning the chicken and veggies quickly builds the dish’s unmistakable smoky flavor.
  • Adjust heat. Cajun seasoning can be mild or hot—add more cayenne or serve with hot sauce for kick.
  • Customize the veggies. Try adding sliced mushrooms, yellow peppers, or a handful of spinach for even more color and nutrition.
  • No wine? Simply use extra chicken broth in its place.
  • Cream substitutions: Half-and-half or evaporated milk can be used for a lighter version, though the sauce may be slightly less thick.

Making Cajun Chicken Pasta Ahead

  • Prep in advance: Chop all vegetables and cut chicken up to a day ahead; store separately in airtight containers in the fridge.
  • Reheating: Warm gently on the stovetop over low heat, adding a splash of milk or broth to loosen the sauce if needed.
  • Freezing not ideal: The creamy sauce is best enjoyed fresh and may separate after freezing and reheating.

Serving Suggestions

  • Bread: Serve with toasted French bread, garlic knots, or warm ciabatta to mop up the sauce.
  • Salad: Pair with a crisp green salad tossed in a tangy vinaigrette to balance the richness.
  • Wine pairing: Try a cold, crisp Sauvignon Blanc or unoaked Chardonnay to complement the spice and cream.
  • For kids or sensitive palates: Omit extra cayenne and offer Parmesan cheese at the table.

Variations and Creative Twists

  • Seafood Cajun Pasta: Add a mix of shrimp and sliced andouille sausage for a New Orleans twist.
  • Vegetarian: Substitute the chicken with sautéed mushrooms or extra vegetables. Use vegetable broth and skip the wine if desired.
  • Lower-calorie version: Swap some cream for milk and use grilled chicken breast.
  • One-pot version: Combine all ingredients in a large pot as in Ree Drummond’s “One-Pot Alfredo”—cook pasta in the sauce for easier clean-up.
  • Extra-cheesy: Fold in grated Parmesan or sharp white cheddar just before serving for a richer sauce.

Homemade Cajun Seasoning Recipe

If you don’t have Cajun spice on hand, make your own! Combine the following:

  • 2 teaspoons paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon thyme
  • 1 teaspoon oregano
  • 1 teaspoon black pepper
  • 1/2 teaspoon cayenne pepper (or more, to taste)
  • 1/2 teaspoon salt

Mix well and store in an airtight container to have on hand!
