Creamy Garlic Parmesan Sauce

This is a quick, creamy garlic Parmesan sauce, close to a classic Alfredo, made with butter, garlic, cream and freshly grated Parmesan. It takes about 15 minutes and four main ingredients.

Made at home, it has none of the stabilizers in jarred sauce, and it’s ready in the time it takes to boil pasta. A wedge of Parmesan costs more up front than a shaker can, but it lasts for weeks and melts far better.

Use this garlic Parmesan cream sauce on pasta, spooned over chicken or drizzled on steamed vegetables.

Ingredients and Swaps

• Butter and garlic: Four cloves of fresh garlic give the sauce its flavor.
• Heavy cream: Thickens as it simmers, with no flour needed. Half-and-half works for a thinner sauce.
• Parmesan: Freshly grated from a wedge on a cheese grater. Pre-grated shaker cheese doesn’t melt smoothly and can turn grainy.
• Italian seasoning: Optional. A pinch of nutmeg is the classic alternative.

Tips for a Smooth Sauce

• Keep the garlic pale. Cook it for under a minute. Browned garlic turns bitter.
• Simmer gently. Small bubbles only. Boiling can make cream separate.
• Add the cheese gradually. Stir it in a handful at a time, off the heat or over very low heat.
• Season last. Parmesan is salty, so taste before adding salt.

Ways to Use It

• Pasta: Enough for 12 ounces of fettuccine or penne. Thin with a splash of pasta water.
• Chicken: Spoon over Juicy Baked Chicken Breasts or Pan-Seared Chicken Thighs.
• Vegetables: Toss with steamed broccoli or spoon over Fluffy Baked Potatoes.
• Pizza: Use it as a white pizza sauce.

Garlic Parmesan Cream Sauce Without Heavy Cream

No cream in the fridge? Milk works if you thicken it with a little flour first. It’s lighter and costs less, and it still clings to pasta.

1. Melt 2 tablespoons butter in a saucepan over medium-low heat and cook the garlic for about 30 seconds.
2. Whisk in 2 tablespoons flour and cook for 1 minute, whisking, so the sauce won’t taste floury.
3. Slowly whisk in 1½ cups milk. Simmer gently, whisking often, until it coats the back of a spoon, 3 to 5 minutes.
4. Take the pan off the heat and stir in ¾ cup freshly grated Parmesan a handful at a time. Season with salt and pepper.

Whole milk gives the creamiest result. Thin it with a splash of pasta water if it gets too thick.

Garlic Parmesan Sauce vs. Alfredo

The original Alfredo from Rome is just butter, Parmesan and a little pasta water tossed with hot fettuccine. The Alfredo most Americans know adds cream, which makes it thicker and easier to get right. This sauce is the American style with extra garlic, so you can use it any time a recipe calls for Alfredo sauce.

Storage and Reheating

• Refrigerate in an airtight container for up to 4 days.
• Reheat gently on the stove over low heat, stirring often.
• Add a splash of milk or cream as it warms to bring back the texture.

Garlic Parmesan Sauce Questions

Why is my sauce grainy?

The heat was too high when the cheese went in, or the cheese was pre-grated. Use freshly grated Parmesan and low heat.

How do I thicken it?

Simmer it for another minute or two. It also thickens as it cools.

How do I make a smooth white sauce for pasta with cream?

Keep the heat low, let the cream simmer gently instead of boiling, and stir in freshly grated Parmesan a little at a time off the heat. High heat and pre-grated cheese are the two most common reasons a cream sauce turns grainy.

Can I freeze garlic Parmesan sauce?

It’s best fresh. Cream sauces can separate and turn grainy after freezing. If you do freeze it, thaw it in the fridge and reheat it slowly over low heat, whisking in a splash of milk.
