Creamy Pesto Sauce

Step-by-Step Instructions

Step 1: Prepare the base

Warm a small saucepan over low to medium heat and add olive oil and butter. Allow the butter to melt gently without browning.

Step 2: Build flavor

Add minced garlic and sauté briefly until fragrant, about 30 seconds. Avoid letting it color, as this can introduce bitterness.

Step 3: Add cream

Pour in the heavy cream and stir gently. Bring it to a light simmer, not a boil, allowing it to thicken slightly.

Step 4: Incorporate pesto

Lower the heat and whisk in the basil pesto until fully combined. The sauce should turn a uniform pale green.

Step 5: Finish with cheese

Gradually add grated Parmesan, stirring continuously until melted and smooth. Season with salt and black pepper to taste.

Step 6: Balance and adjust

If desired, add a few drops of lemon juice to brighten the sauce. Adjust consistency with a splash of cream or pasta water if needed.

FAQs

Can I make this sauce dairy-free?
Yes, substitute heavy cream with full-fat coconut milk and use nutritional yeast instead of Parmesan for a dairy-free alternative.

Why did my sauce separate while reheating?
High heat can cause the fats to split. Always reheat slowly over low heat and stir continuously.

Can I add protein directly into the sauce?
Absolutely. Cooked chicken, shrimp, or even sautéed mushrooms can be folded in at the end for a complete one-pan meal.
