Pro Tips for Creamy Crawfish Fettuccine
- Reserve Pasta Water: Keep a cup of pasta water before draining. It helps loosen the sauce if it gets too thick.
- Don’t Overcook Crawfish: Add the crawfish near the end to avoid making them rubbery. Heat them just enough to absorb the flavors.
- Adjust Heat to Taste: Start with a little cayenne and add more if needed. The spice level is flexible.
- Use Fresh Parmesan: Pre-shredded cheese can clump. Grate fresh Parmesan for a smoother, creamier sauce.
- Toss Gently: Stir the pasta gently once added to the sauce to avoid breaking the noodles and keep the texture just right.
