Creamy Pesto Sauce

Creamy pesto sauce combines basil pesto, olive oil, and cream for a smooth, versatile sauce that’s ideal for pasta, pizza, or meal prep.

Creamy Pesto Sauce is my 10‑minute answer to restaurant‑quality flavor at home. It’s bright, garlicky and nutty, as a classic basil pesto should be. But a generous splash of cream turns it velvety enough to cling to pasta or drizzle over roasted vegetables.

It’s a sauce I can always rely on to rescue plain noodles, grilled chicken, or even warm crusty bread. Big flavor, minimal effort, and ready before your water hits a rolling boil.

Creamy Pesto in 3 Simple Steps

1. Blend pesto – Basil, garlic, pine nuts, Parmesan, salt, and olive oil.
2. Stir in cream – Gently fold into the pesto until smooth.
3. Taste & adjust – Add more salt if needed. Serve warm or cold.

Creamy Pesto Sauce Ingredients

• Basil – Fresh, fragrant leaves with no stems. I look for smaller leaves when I can, they’re more tender and have great flavor.
• Garlic – Two large cloves is my sweet spot. More than that tends to take over the sauce.
• Pine Nuts – I usually toast the pine nuts for just a minute or two to bring out their nuttiness. I usually store extras in the freezer so they don’t go rancid.
• Parmesan – Instead of pre-shredded cheese, I like to finely grate fresh from a block of Parmigiano Reggiano; it blends in better.
• Olive Oil – I use a mild or medium extra-virgin olive oil to keep the basil flavor front and center.
• Cream – Heavy cream gives the sauce its richness.

How to Make Creamy Pesto Sauce (Step-by-Step)

1. Prep the ingredients – Rinse and pat dry basil. Toast the pine nuts if desired. Peel garlic.
2. Blend the base – In a food processor, pulse the basil, garlic, pine nuts, Parmesan, and salt until finely chopped. Scrape down the sides.
3. Stream in olive oil – With the machine running, pour in oil slowly until the mixture becomes smooth and emulsified.
4. Add cream – Transfer the pesto to a bowl and gently stir in the cream.
5. Taste and serve – Add more salt if needed and use immediately, or chill for later.

Why This Creamy Pesto Works

1. Stirring in the cream after blending keeps the basil bright and the texture silky. Heating everything together would dull the flavor and color.
2. Using a high-speed food processor gives you a smooth, creamy sauce in seconds—no pounding or muddling required.
3. The cream rounds it out—giving the pesto enough richness to cling to pasta or stand up to grilled meat, without muting the fresh basil or garlic.

Make-Ahead & Storage

Creamy pesto is best used fresh, but it keeps well in the refrigerator for up to 3 days. If storing, press plastic wrap directly on the surface to help prevent browning. For freezing, omit the cream and stir it in after thawing.
