Creamy garlic chicken fettuccine is a one-pan sauce built on seared chicken, toasted garlic, and grated parmesan. The sauce thickens from the pasta water, not from a heavy cream reduction, so it coats the noodles instead of pooling under them.
Weigh the parmesan and grate it yourself. Pre-shredded cheese contains starch that turns the sauce grainy at 80°C (176°F). Fresh grating takes two minutes and gives a glossy, elastic sauce.
The whole dish takes 50 minutes from cold pan to plated bowl. Read the steps once, set your timer, and do not walk away from the garlic.

About the Ingredients
340 g (12 oz) dried fettuccine
Dried fettuccine holds sauce better than fresh. Substitute tagliatelle or linguine at the same weight; check the package time and pull it one minute early.
680 g (1.5 lb) boneless, skinless chicken breasts, halved horizontally
Halving the breasts gives two thin cutlets per piece, which cook through before the crust burns. Substitute boneless thighs and add four minutes to the sear.
12 g (4 cloves) garlic, finely minced
Fresh garlic only here; jarred garlic tastes metallic when toasted. Buy firm, tight heads and discard any green sprouts, which turn bitter.
45 g (3 tbsp) unsalted butter, divided
Butter browns faster than oil and builds the nutty base. Substitute ghee if you need a higher smoke point; use the same weight.
15 g (1 tbsp) olive oil
Oil raises the smoke point of the butter so the chicken sears instead of scorching. Substitute avocado oil with no change to timing.
240 g (1 cup) heavy cream, 36% fat
Full-fat cream is required; light cream curdles at a simmer. Substitute 200 g whole milk plus 40 g butter whisked in at the end for a lighter sauce.
60 g (about 3/4 cup) parmesan, finely grated
Grate on a microplane so the cheese melts without clumping. Substitute pecorino romano for a sharper, saltier sauce; reduce added salt.
1 g (1/4 tsp) fine sea salt, plus more for the pasta water
Salt the water at 10 g per 4 liters so the pasta seasons from within. Substitute kosher salt by weight, not volume.
0.5 g (1/4 tsp) freshly ground black pepper
Grind to order; pre-ground pepper loses its oils. Substitute white pepper for a milder heat that disappears into the cream.
10 g (1/3 cup) fresh flat-leaf parsley, chopped
Add parsley off heat so it stays green. Substitute basil, added at the same moment, for a sweeter finish.
Tips & Tricks
Do Not Boil the Cream
Keep the sauce at a bare simmer, 85-90°C (185-194°F). A rolling boil splits the fat and the sauce turns oily; pull the pan off heat the moment bubbles ring the edge.
Reserve Two Cups of Pasta Water
Starchy water is the emulsifier. Without it the cheese seizes into strings; add it one splash at a time until the sauce coats the back of a spoon.
Toast Garlic Briefly, Not Brown
Thirty to forty-five seconds at medium heat is enough. Garlic goes from sweet to acrid in ten seconds, so have the cream measured and ready beside the stove.
Pro Tips
Step-by-Step Instructions
1. Boil the Pasta
Bring 4 liters of water to a rolling boil at 100°C (212°F) and add 10 g salt. Cook 340 g fettuccine for 1 minute less than the package time, until it bends but still has a chalky center (bite a strand to check). Reserve 480 ml (2 cups) pasta water and drain.
2. Dry and Season Chicken
Pat 680 g chicken cutlets dry with paper towel and season both sides with the sea salt and pepper. Dry meat sears brown; wet meat steams grey (moisture must leave the surface before browning begins).
3. Sear the Chicken
Heat the olive oil and 15 g butter in a 30 cm skillet over medium-high heat to 190°C (375°F). Sear the cutlets 5 to 6 minutes per side until deep golden brown and the thickest part reads 74°C (165°F) on an instant-read thermometer. Transfer to a board.
4. Toast the Garlic
Lower the heat to medium and add the remaining 30 g butter. Add 12 g minced garlic and stir 40 seconds until fragrant and pale gold (it should smell sweet, never sharp). Pour in 240 g cream immediately to stop the cooking.
5. Build the Sauce
Simmer the cream at 85-90°C (185-194°F) for 3 minutes until it thickens slightly and bubbles just at the pan edge. Whisk in 60 g parmesan off heat until the sauce is smooth and glossy (no visible grains).
6. Emulsify with Pasta Water
Add the drained fettuccine and 120 ml (1/2 cup) reserved pasta water. Toss over low heat 2 minutes until the sauce clings to the strands and pools slowly when you lift a fork. Add more water 30 ml at a time if it tightens.
7. Slice and Finish
Slice the rested chicken against the grain into 1 cm strips. Fold the chicken and any board juices into the pasta with 10 g parsley. Taste and adjust salt; serve at once in warm bowls.
Delicious Variations
Lemon Basil Version
Add 6 g lemon zest and 15 g lemon juice with the parmesan, and swap parsley for torn basil. The acid cuts the cream and brightens the garlic.
Mushroom and Thyme
Sear 200 g sliced cremini in the same pan before the garlic until browned, then proceed. Add 2 g fresh thyme with the cream for an earthy sauce.
Spicy Arrabbiata Cream
Add 3 g red pepper flakes with the garlic and 100 g crushed tomatoes before the cream. Simmer 5 minutes longer for a pink, fiery sauce.
How to Store Creamy Garlic Chicken Fettuccine
Refrigerator
Store in an airtight container up to 3 days. The sauce thickens cold; loosen with 30 ml water per portion during reheating.
Freezer
Freeze the sauce and chicken alone up to 2 months; cream sauces separate when frozen with pasta. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat gently in a covered skillet over low heat, 60-70°C (140-158°F), with a splash of water, stirring 4 to 5 minutes until loose and glossy. Never microwave on high, which splits the cream.
Frequently Asked Questions
Q: Why did my creamy garlic sauce turn grainy?
The sauce turned grainy because the pan was too hot or the parmesan was pre-shredded and starchy. Add cheese off heat at 85°C (185°F) or lower and grate fresh. Whisk in 15 ml pasta water to pull it back together.
Q: Can I make creamy garlic chicken fettuccine ahead of time?
You can make the sauce and sear the chicken up to 2 days ahead and refrigerate them separately. Boil fresh pasta and combine at serving time, because held pasta absorbs the sauce and turns dry. Reheat the sauce gently with 30 ml water per portion.
Q: How do I stop the chicken from drying out?
Sear thin cutlets fast over medium-high heat and pull them at 74°C (165°F) internal. Rest them 5 minutes before slicing so the juices redistribute. Slicing against the grain shortens the fibers and keeps each bite tender.
Q: What can I use instead of heavy cream?
Use 200 g whole milk plus 40 g butter whisked in at the end, or 220 g full-fat evaporated milk. Both simmer without curdling, though the sauce will be thinner. Do not use half-and-half at a boil, which splits.
Q: Is this dish very garlicky?
It is garlic-forward but rounded, since 12 g toasted in butter turns sweet rather than sharp. For a milder sauce, use 8 g garlic and add it with the cream instead of toasting. Add raw garlic at the end only if you want a sharp bite.
Cook the pasta, sear the chicken, and watch the sauce come together in one pan. Weigh, watch, repeat.
