How to Make Classic Mornay Sauce
STEP 1. Heat the milk. In a small saucepan, add whole milk and salt, whisk together, and heat until just boiling.
STEP 2. Prepare the roux. In a heavy-bottomed saucepan, melt butter over low heat, blend in flour, and cook slowly while stirring continuously until it becomes a white roux.
STEP 3. Add the milk mixture. Remove the roux from heat and pour in the hot milk while whisking vigorously to ensure a smooth blend.
STEP 4. Return to heat. Place the mixture back on medium heat, stirring until the sauce comes to a boil, then boil for 1 minute.
STEP 5. Incorporate seasonings and cheese. Remove from heat, add salt, pepper, and grated cheese, stirring until cheese is fully melted.
STEP 6. Finish the sauce. Season with nutmeg and adjust salt and pepper, then stir in remaining butter until melted. Serve warm.
Why This Recipe Works
The balance between the creamy béchamel sauce and the melted cheese creates a delightful texture that’s neither too heavy nor too light. The gradual heating allows the flavors to meld perfectly, while the roux ensures a stable base for the cheese to combine seamlessly. The result is a sauce that clings beautifully to your chosen ingredients – whether pasta or vegetables – ensuring a satisfying flavor in every bite.
