Ingredients You’ll Need

2 tablespoons unsalted butter: This rich base adds creaminess to the sauce. For a lighter alternative, consider using olive oil instead.
3 cloves garlic, minced: Fresh garlic brings a punch of flavor and aroma. Feel free to use garlic powder in a pinch, but fresh is best!
1 cup heavy cream: This is the heart of the sauce that creates its luxurious texture. For a lower-fat option, half-and-half works too, although it may alter the richness.
4 ounces cream cheese or mascarpone: Adds a velvety smoothness; mascarpone can make it even creamier. Cream cheese is more common, so choose based on what you have.
3/4 cup finely grated Parmesan cheese: This cheese provides a salty, nutty flavor; aged Parmesan works great here. Nutritional yeast is a good substitute for a non-dairy option.
1/2 cup basil pesto: Store-bought is convenient, but homemade really shines with fresh flavor. Adjust based on your preference for basil intensity.
Juice and zest of 1 lemon: Brightens the sauce; the zest adds aromatic oils. If lemons aren’t available, a splash of white wine vinegar can be used.
1/4 teaspoon kosher salt: Enhances overall flavors. When seasoning, remember to taste and add more if needed.
1/8 teaspoon black pepper: A pinch gives depth to the sauce. If you want some heat, consider adding a dash of freshly cracked black pepper.
Pinch of red pepper flakes, optional: Adds a nice kick; perfect for those who enjoy a bit of spice.
Pasta water, as needed (start with 1/4 cup): This starchy water is magic for adjusting the sauce’s consistency without watering it down.

How to Make Pesto Cream Sauce

Melt the Butter: In a large skillet over medium heat, melt 2 tablespoons of unsalted butter. Add the minced garlic and cook for 30–60 seconds, just until fragrant—be careful not to let it brown.
Add the Cream: Pour in 1 cup of heavy cream and bring it to a gentle simmer. Cook for 2–3 minutes, stirring regularly. You want it to bubble around the edges, giving it a light, frothy feel.
Incorporate the Cheese: Lower the heat to medium-low and stir in 4 ounces of cream cheese until smooth. Gradually whisk in 3/4 cup of finely grated Parmesan cheese a handful at a time until well combined; avoid boiling as it can cause the sauce to break.
Add Pesto: Once the cheeses have melted and created a smooth sauce, remove it from heat, and stir in 1/2 cup of basil pesto until fully combined. This helps keep the fresh flavor of the pesto intact.
Adjust Consistency: Add warm pasta water, starting with 1/4 cup, until the sauce coats the back of a spoon. Adjust with more if needed to reach your desired consistency.
Season It Up: Season with 1/4 teaspoon kosher salt, 1/8 teaspoon black pepper, and a pinch of red pepper flakes, if desired. Give it one last stir and taste; adjust as necessary.
Serve Immediately: Toss the sauce with hot pasta and finish with extra Parmesan and a drizzle of olive oil, if you like. Enjoy your creation while warm!

Storing & Reheating

Leftover pesto cream sauce can be stored at room temperature for up to 2 hours. To refrigerate, place it in an airtight container, where it will keep for 3-4 days in the fridge. If you wish to freeze it, pour the sauce into a freezer-safe container or bag, and it can be stored for up to 3 months. When you’re ready to enjoy it again, just reheat on low heat on the stovetop, stirring frequently until warm. Note that the texture might slightly change — if it thickens, just add a splash of cream or pasta water to freshen it up.

Chef’s Helpful Tips

Ensure your butter and cream cheese are at room temperature for smoother incorporation into the sauce.
Stir constantly when adding the cheese to avoid clumping; this helps achieve that creamy consistency we love.
Taste your sauce often! This allows you to adjust seasoning as per your preference, ensuring the best flavor every time.
If your sauce gets too thick, don’t hesitate to add more pasta water gradually until it has the right consistency.
Experiment with different types of pesto—nut-free or kale-based can create wonderful variations.

Pesto cream sauce is a versatile delight that can become a household favorite. Whether served over pasta, as a dip, or a dressing, it brings a little touch of joy to everyday meals. Don’t shy away from making this recipe your own by changing it up with various ingredients or pairings.

Recipe FAQs

Can I use store-bought pesto?

Absolutely! Store-bought pesto is a convenient option and works perfectly in this recipe. If you have the time, homemade pesto can enhance the sauce’s flavor dramatically.

Can I make this sauce dairy-free?

Definitely! For a dairy-free version, substitute the cream with coconut cream or a plant-based creamer. For cheese, try nutritional yeast or a vegan cream cheese alternative.

How do I know when my sauce is done?

The sauce should be smooth and creamy without any visible lumps once the cheese is fully melted and combined. A gentle simmering but not boiling action achieves the perfect consistency.

Can I prepare this sauce ahead of time?

Yes, you can prepare the sauce ahead of time and store it in the refrigerator. Just reheat gently on the stove before serving, adding a bit of water or cream if needed to loosen it up.
