Boil the pasta: In a large pot, cook 1 lb spaghetti according to package instructions. Reserve some pasta water before draining.
Sauté shallot: In a large skillet over medium heat, melt 2 Tbsp butter and add ⅓ cup diced shallot. Cook for 2–3 minutes, until soft and translucent.
Add garlic + flour: Stir in 2 tsp grated garlic and cook for 30 seconds. Add 2 Tbsp flour and stir constantly for 1–2 minutes to remove the raw taste.
Deglaze with wine: Remove skillet from heat and stir in ¼ cup white wine.
Build the sauce: Return to heat and stir in 1 cup heavy cream, ⅓ cup parmesan, 1 tsp salt, ½ tsp black pepper, ¼ tsp red pepper flakes, ⅛ tsp nutmeg, and the zest and juice of 1 lemon. Simmer until the sauce thickens and coats the back of a spoon.
Combine: Add cooked pasta directly to the sauce using tongs. Toss until well coated, thinning with reserved pasta water as needed.
Garnish and serve: Top with chopped parsley and serve warm.
Recipe Notes:
Don’t skip the flour step – it helps thicken the sauce properly.
Use tongs to transfer pasta – it brings some starchy water with it to help the sauce cling.
Add pasta water as needed – to thin the sauce to your liking.
Grate garlic and lemon fresh – for the best flavor.
Serve immediately – the sauce is best hot and creamy.
