Mornay Sauce
Mornay sauce is a rich, cheesy béchamel variation with Swiss and Parmesan, perfect for gratins, vegetables, or seafood dishes, offering a creamy, savory flavor profile.
Ingredients
Instructions
- Bring milk, minced onion, and bay leaf to a full boil.
- Let the mixture stand for 10 minutes to infuse flavors.
- Strain the milk to remove onion and bay leaf.
- Over low heat, melt butter in a saucepan.
- Add flour to the melted butter and cook until light brown.
- Gradually add the strained milk and heavy cream, stirring constantly until the mixture starts to boil.
- Stir in grated Swiss cheese and Parmesan cheese until melted and smooth.
- Season with salt and pepper to taste.
Tips & Substitutions
For a richer flavor, consider adding a pinch of nutmeg or a splash of white wine. If Swiss cheese isn't available, Gruyère or even a mild cheddar can be substituted for a different taste. When cooking the flour, ensure it doesn't darken too much to prevent a bitter taste. Stirring continuously while adding the milk is crucial for a smooth sauce without lumps.
Serving Suggestions
Mornay sauce is perfect for drizzling over vegetables, such as steamed broccoli or cauliflower, and pairs beautifully with any baked pasta dishes. It can also be used as a base for a cheese fondue. For a comforting meal, serve it alongside Yams In Orange Sauce for a delightful contrast.
Storage & Reheating
Store leftover Mornay sauce in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm it over low heat, stirring frequently to restore its creamy texture. If the sauce thickens too much, whisk in a little milk or cream to reach the desired consistency.
