3. Step-by-Step Cooking Instructions & Crisping Secrets
The key to achieving the perfect creamy sauce is to not overcook the mushrooms.
Cook them until they release their liquid and start to brown, then add the heavy cream and stir to combine.
Bring the mixture to a simmer and cook for 2-3 minutes until the sauce has thickened slightly.
Finally, stir in the Parmesan cheese until melted and well combined.

Meal-Prep Storage & Crispy Air-Fryer Reheating Guide
• Cool Before Sealing: Let cooked portions cool for 10 minutes before sealing in glass containers so steam never softens the crust (keeps 4 days in the fridge).
• Sauce on the Side: Store dips, drizzles, and fresh herbs separately until right before serving.
• 3-Minute Crispy Reheat: Reheat in a 380°F (193°C) air fryer or dry cast-iron skillet for 3–4 minutes to restore shatteringly crisp edges.
