I like to sauté small pieces of seasoned chicken and broccoli in skillet while the fettuccini is cooking, you can serve it with the pasta or on the side. Seasoned grilled shrimp are fantastic with this as well.
Cook the box of fettuccini on the stove in a large Dutch oven, approximately 15 minutes at a hard boil. Be sure to add salt to your water.
When the fettuccini is done, reserve pasta water for sauce and drain pasta in a strainer. Return the Dutch oven to the stove with the heat on low.
Add butter to the pot and make sure the butter doesn't burn. Add the pasta back to the pot and use tongs to get all of the fettuccini coated with butter.
Add parmesan cheese to the pasta and continue to use the tongs to keeps the pasta coated. Add pasta water, cream, salt, and pepper. Continue to combine ingredients on low until sauce is creamy and covering pasta completely.
Serve alfredo with your choice of meat and vegetable.
