I can never resist a silky lemon garlic sauce that makes pasta shine and turns simple chicken into something special. This one is rich, bright, and loaded with flavor in every spoonful.

Jump to Recipe

I’m obsessed with this creamy lemon garlic sauce because it hits every craving at once: rich, bright, tangy, savory, and just a little sharp in the best way. I love it over chicken when I want dinner to feel extra, and I adore it tangled into pasta when I’m pretending I have my life together.

The garlic gives it that punchy bite I can’t quit, while lemon juice keeps the whole thing fresh instead of heavy. And that glossy, creamy finish?

Ridiculous. But the real reason I keep coming back is simple.

It tastes like restaurant sauce without the fuss.

Ingredient Quantities

2 tablespoons olive oil

2 tablespoons unsalted butter

4 garlic cloves, minced

1 cup low sodium chicken broth

1 cup heavy cream

1/2 cup freshly grated Parmesan cheese

2 tablespoons fresh lemon juice (about 1 lemon)

1 teaspoon lemon zest

1 tablespoon all purpose flour (optional, for thicker sauce)

How to Make this

Print Recipe (No Advertisments)

1. Heat 2 tablespoons olive oil and 2 tablespoons unsalted butter in a large skillet over medium heat until butter is melted and sizzling.

2. Add 4 minced garlic cloves and cook 30 to 45 seconds, stirring constantly, until fragrant and just beginning to turn golden.

3. If using the flour for a thicker sauce, sprinkle 1 tablespoon all purpose flour over the garlic and fat, stir continuously for 1 minute to cook out the raw flour taste.

4. Pour in 1 cup low sodium chicken broth while whisking to dissolve any flour and scrape up browned bits from the pan.

5. Stir in 1 cup heavy cream and bring to a gentle simmer, reducing heat to medium low and simmer 3 to 5 minutes until the sauce starts to thicken.

6. Add 1/2 cup freshly grated Parmesan cheese, 2 tablespoons fresh lemon juice, and 1 teaspoon lemon zest, stirring until the cheese melts and the sauce is smooth.

7. Season with 1/2 teaspoon kosher salt, 1/4 teaspoon freshly ground black pepper, and 1/8 teaspoon red pepper flakes if using; taste and adjust seasoning or lemon to preference.

8. Simmer another 1 to 2 minutes to meld flavors and reach desired consistency; if sauce becomes too thick, thin with a splash of chicken broth or reserved pasta water.

9. Remove from heat, stir in chopped fresh parsley, and spoon over cooked pasta or cooked chicken. Serve immediately.

FAQ

Can I make this sauce ahead of time? Yes. Cool completely, store in an airtight container in the refrigerator for up to 3 days. Reheat gently on low heat, stirring frequently to prevent separation.

How do I thicken the sauce if it is too thin? Whisk 1 tablespoon flour into 1 to 2 tablespoons of cold water to make a slurry, then stir into the simmering sauce and cook 1 to 2 minutes. For a gluten free option, use 1 teaspoon cornstarch mixed with cold water instead.

Can I use milk instead of heavy cream? You can, but the sauce will be thinner and less rich. Use whole milk for best results and cook gently; finishing with a little extra Parmesan can help improve body and flavor.

Is this sauce suitable for freezing? Cream based sauces can separate when frozen and thawed, so freezing is not recommended. If you must freeze, store tightly and reheat slowly while whisking to help reincorporate fats.

How do I prevent the sauce from curdling? Cook over low to medium heat and avoid boiling after adding the cream. Temper any hot liquid by slowly whisking it into the cream, and stir constantly while reheating.

What pairs best with this sauce and serving tips? It is excellent with grilled or pan seared chicken breasts, tossed with pasta, or drizzled over roasted vegetables. Finish with extra lemon zest and chopped parsley for brightness and color.

Creamy Lemon Garlic Sauce For Chicken Or Pasta! Recipe Substitutions and Variations

Heavy cream: substitute with 1 cup half and half plus 2 tablespoons melted butter for richness; or 1 cup whole milk thickened with 1 tablespoon cornstarch; or use full fat Greek yogurt thinned with a little milk (stir in off heat to avoid curdling).
Parmesan cheese: swap with grated Pecorino Romano for a saltier, tangier profile; or use aged Asiago; or use 2 to 3 tablespoons nutritional yeast for a dairy free, cheesy flavor.
Low sodium chicken broth: replace with low sodium vegetable broth for a vegetarian version; or use 3/4 cup water plus 1/4 cup dry white wine for brightness; or dissolve 1 teaspoon low sodium bouillon in 1 cup hot water.
Unsalted butter: use ghee for a nuttier flavor and higher smoke point; or use an equal amount of neutral oil plus 1 teaspoon butter flavoring; or replace with vegan buttery spread for a dairy free option.

Pro Tips

1) Toast the garlic gently and keep the heat moderate. Garlic goes from fragrant to bitter fast, so 30 to 45 seconds over medium is ideal. If it starts browning too quickly, pull the pan off the heat for a few seconds.

2) Use freshly grated Parmesan and add it off the heat or over very low heat. Pre-grated cheese often contains anti-caking agents that prevent smooth melting. Adding the cheese too hot can make the sauce grainy, so stir until just smooth.

3) Reserve a ladle of pasta water before draining. The starchy water is perfect for loosening a sauce that gets too thick without diluting flavor, and it helps the sauce cling to pasta.

4) Adjust lemon and seasoning at the end, not the beginning. Lemon brightens the whole sauce, so start with the listed amount and add more in small increments after tasting. Low sodium broth lets you control salt more easily.
