This cheese sauce is a versatile and flavorful addition to many dishes, perfect for enhancing your meals.
Melt the butter in a saucepan over medium heat.
Ensure the butter doesn't brown to maintain a light-colored sauce.
Add the flour to the melted butter and whisk until smooth and bubbly.
Cook the mixture for a minute to remove the raw flour taste.
Gradually pour in the milk while whisking continuously to avoid lumps.
Warm the milk slightly before adding for a smoother sauce.
Bring the mixture to a gentle boil, stirring constantly, until it thickens.
Reduce the heat if the sauce thickens too quickly to prevent scorching.
Lower the heat and stir in the cheddar and parmesan cheeses until melted and smooth.
Add the cheese in small batches to ensure it melts evenly.
Season the sauce with salt and black pepper to taste.
Taste the sauce before adding salt, as the cheese may already be salty.
Serve the cheese sauce warm over your favorite dish or as a dip.
Keep the sauce warm to maintain its creamy consistency.
