Ingredients You’ll Need

Here’s what you need to make this luscious homemade lemon garlic sauce:

• Butter: The base of all good things. Use unsalted if possible.
• Shallot (or onion): Finely chopped. Shallots give a mellow sweetness, but yellow onion works too.
• Garlic cloves (minced): Core flavor; bold and savory.
• Fresh lemon juice + zest: Adds brightness and that iconic citrus pop.
• Chicken broth or vegetable broth: For thinning and boosting flavor. Use low-sodium if you’re watching your salt.
• Whole milk, half-and-half, or heavy cream: Choose your richness level. Milk for light, cream for indulgent.
• Thyme or Italian seasoning: Dried or fresh both work.
• Cornstarch slurry (optional): Helps thicken the sauce if you like it extra velvety.

Optional add-ins from readers include grated Parmesan, a pinch of chili flakes, or even chopped basil if you’re feeling fancy.

How to Make Creamy Lemon Garlic Sauce

Making this creamy lemon garlic sauce is easier than scrolling through takeout apps—trust me!

Step 1: Sauté the Aromatics

Start by melting butter in a medium saucepan over medium heat. Once it’s melted, add the finely chopped shallot (or onion) and cook for about 3 minutes until it softens up. Then, toss in the minced garlic and sauté until it’s fragrant. Now, whatever you do, don’t inhale directly over the pan unless you’re in the mood for a garlic facial. (Been there, done that!)

Step 2: Add Lemon & Broth

Next, add the lemon zest and juice. Give it a quick stir to let that citrus goodness fill the air. Then, pour in the chicken or vegetable broth and stir everything together. This is where the magic of the lemon garlic sauce begins!

Step 3: Stir in Dairy

Now it’s time for the dairy. Slowly pour in your warmed milk, half-and-half, or cream while stirring continuously. Warming the dairy first helps prevent curdling. Trust me, it’s a small step that makes a big difference. Once that’s in, sprinkle in some thyme or Italian seasoning and reduce the heat to a gentle simmer. Let it cook for about 10 minutes, stirring occasionally, until it thickens to your liking.

Step 4: Thicken If Needed

If you like your sauce thicker, here’s the secret: mix 1 tablespoon of cornstarch with 2 tablespoons of cold water to make a slurry, then add it slowly into the sauce while whisking. Let it bubble for another couple of minutes until it reaches your desired consistency.

Tips for Success

Here’s the thing about creamy sauces—they can go from perfect to split in a hot second. So here’s what to keep in mind when making this creamy lemon garlic sauce:

For extra flavor, consider adding a tablespoon of grated Parmesan or drizzling a little olive oil into the creamy garlic sauce before serving.

Warm the dairy before adding it to avoid curdling from the lemon’s acidity.

Use cream for richness, or milk for a lighter, healthier version.

Don’t boil the sauce—a gentle simmer is the key to keeping it smooth and creamy.

Stir frequently to ensure your lemon garlic sauce remains silky and smooth.

Notes and Substitutions

Don’t sweat it if you’re missing an ingredient—this sauce is super forgiving.

• No shallots? Use finely chopped onion.
• Out of fresh garlic? Sub in 2 teaspoons garlic powder.
• Need dairy-free? Use full-fat oat milk with a splash of olive oil.
• Low-fat version? Stick with whole milk.
• Want more flavor? Add a few sun-dried tomatoes or chopped green onions.

Gluten-free? This sauce is naturally so—just skip the slurry or use arrowroot powder instead.

This is also a great option for folks following low-carb or keto eating styles.
