Cook fettuccine until just shy of al dente in a large pot of boiling, well-salted water. When done cooking, drain in a colander.
About 5 to 7 minutes before pasta is done cooking, melt butter and heavy cream together in a large skillet over medium heat.
Heat until sauce begins to simmer, stirring constantly (do not boil). Reduce heat to medium low.
Stir in Parmesan cheese in batches. Season with salt and pepper to taste.
Toss pasta and sauce together for a minute or two, until sauce thickens and coats noodles.
Season with additional salt and pepper, if needed. Then remove from heat.
Serve immediately, topped with additional Parmesan. Enjoy!
Notes
To get the timing right, make sure to start cooking your pasta before you make the sauce. You want to cook the pasta until it's just shy of al dente (it will finish cooking in the sauce). For best results, use top quality ingredients for this recipe (no canned or pre-shredded Parmesan) and avoid making substitutions.Check out the information before this recipe card for helpful tips, step-by-step photos, variations, serving suggestions, and more!
