🥕Ingredients
Tap to check off as you go
- 12 oz fettuccine
- 1/2 cup unsalted butter
- 1 1/2 cups heavy cream
- 1 1/2 cups freshly grated Parmesan
- 2 cloves garlic, minced
- 1/2 tsp salt
- 1/4 tsp black pepper
- 2 tbsp fresh parsley
📋Instructions
- 1
Bring a large pot of salted water to a boil. Cook fettuccine according to package directions until al dente. Reserve 1 cup of pasta water before draining.
- 2
While the pasta cooks, melt butter in a large skillet over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
- 3
Pour in heavy cream and bring to a gentle simmer. Cook for 2-3 minutes, stirring occasionally, until the cream thickens slightly.
- 4
Lower the heat and gradually whisk in the grated Parmesan cheese until smooth and creamy. Season with salt and pepper.
- 5
Add the drained fettuccine to the sauce and toss to coat. If the sauce is too thick, add reserved pasta water a little at a time until desired consistency is reached.
- 6
Serve immediately, garnished with fresh parsley and extra Parmesan if desired.
💡 Pro Tips
- •Use freshly grated Parmesan—pre-shredded contains anti-caking agents that prevent smooth melting.
- •Reserve pasta water before draining; the starch helps bind the sauce to the pasta.
- •Don't boil the cream; keep it at a gentle simmer to prevent curdling.

Pro Tips for Perfect Alfredo Every Time
Pro Cooking Tip
Always grate your Parmesan from a block—it melts much smoother and gives a richer flavor. Pre-shredded cheese has additives that can make the sauce grainy.
The key to a silky Alfredo sauce is patience and low heat. If you rush and crank up the heat, the cream can separate and the cheese can clump. Stir constantly while adding the Parmesan, and keep the flame low. Also, don't skip the pasta water—it's liquid gold for adjusting consistency.
Serving Suggestions
This Alfredo is delicious on its own, but you can easily turn it into a heartier meal. Add grilled chicken, sautéed shrimp, or steamed broccoli for extra protein and veggies. A side of garlic bread and a simple green salad complete the feast. For a lighter version, swap half the cream for whole milk and use less butter.
