Step 1

Melt the butter in a pan then add the onion. Cook until soft and translucent.

Step 2

Add the garlic, basil and dried herbs (if using) and cook for another 30 seconds.

Step 3

Pour in the cream and allow to come to a simmer. Simmer for 5-7 minutes until the sauce covers the back of a spoon easily.

Step 4

Transfer sauce to a food processor or blender (or use an immersion blender) and blend until smooth.

Step 5

Pour the sauce back into the pan and add lemon juice, salt and pepper to taste. Bring to a simmer and add cooked pasta or serve over cooked chicken.
