Can I use heavy cream instead of light cream?

Absolutely. Heavy cream will make the sauce even richer and lower the carb count slightly. It may also thicken faster, so keep an eye on the simmering time.

Is there a dairy-free alternative for this keto sauce?

You can try using full-fat coconut cream in place of the light cream. The flavor will be slightly different but still delicious. The Parmesan can be swapped for nutritional yeast for a vegan option.

How can I prevent the sauce from separating?

Make sure to temper the pesto by adding the hot cream gradually while pulsing, and avoid boiling the final sauce. Low, gentle heat is key to a smooth emulsion.

Easy Keto Basil Cream Sauce Recipe – Low Carb & Versatile

Name: Basil Cream Sauce
Prep time: 15 min
Cook time: 25 min
Total time: 40 min
Yield: 4
Cuisine: Keto
Ingredients: cups fresh basil leaves; cloves garlic, minced; /4 cup olive oil; ounces pine nuts; /2 cup grated Parmesan cheese; salt and pepper to taste; pint light cream

Ingredients

cups fresh basil leaves
cloves garlic, minced
/4 cup olive oil
ounces pine nuts
/2 cup grated Parmesan cheese
salt and pepper to taste
pint light cream

Instructions

Step 1

First, I place the fresh basil leaves and minced garlic in a food processor. With the motor running, slowly drizzle in the olive oil until the mixture starts to emulsify and look like a coarse pesto. This takes about 40 seconds. Next, add the pine nuts and grated Parmesan cheese, then blend for another minute until everything is well combined. Meanwhile, slowly heat the light cream in a small saucepan over low heat, just until it starts to simmer. Carefully pour about half of the hot cream into the processor with the basil mixture and pulse a few times to incorporate. This tempers the pesto and helps it meld with the cream without clumping. Pour the whole mixture back into the saucepan with the remaining cream and stir gently. Let it simmer over low heat for about 5 minutes, stirring occasionally, until the sauce thickens to your liking. Season with salt and pepper to taste. I find that letting it sit off the heat for a minute allows the flavors to settle beautifully before serving.

Chef's Tip

If you want to save a few calories, toast the pine nuts in a dry pan first. It deepens their nutty flavor and adds a lovely aroma to the sauce. I do this step while the cream is heating.

Storage Tips

Store any leftover sauce in an airtight jar in the refrigerator for up to 5 days. Reheat gently over low heat, stirring in a splash of water or cream if it thickens too much.

Variation Tips

For a lighter version, substitute the pine nuts with toasted sunflower seeds. If you're not strictly keto, this sauce is wonderful over a bed of zucchini noodles or stirred into steamed green beans. You could also add a pinch of red pepper flakes for a gentle kick.
