After draining boiled potatoes, return them to the hot pot for 1-2 minutes to evaporate excess moisture, ensuring creamy rather than gluey mashed potatoes.

Heat the half and half and butter together before adding to the potatoes to prevent temperature shock and achieve silky-smooth consistency without overworking the potatoes.

Fold in the Boursin cheese last and gently to preserve its delicate herb flavors and prevent them from becoming bitter or muted from prolonged heat exposure.

Yukon Golds have higher natural butter fat content and waxy texture that creates the perfect creamy consistency without needing excess dairy, unlike starchy Russets.

Add salt and seasoning blend to potatoes before the dairy, then taste and adjust after incorporating Boursin—this prevents over-seasoning since the cheese adds significant salt.
