Step‑by‑Step Instructions for Cheese Sauce
Step 1: Melt the Butter
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Stir it gently with a wooden spoon until it completely liquefies and becomes bubbly, taking care not to let it brown—this should take about 1 minute. The butter creates a rich base for your Ultimate Cheese Sauce.
Step 2: Make the Roux
Once the butter is melted, whisk in 4 tablespoons of all-purpose flour until fully combined. Cook this mixture for 1-2 minutes, stirring constantly, until it bubbles and takes on a light golden hue—this roux will help thicken your sauce and provide a robust flavor.
Step 3: Add the Milk
Gradually pour in 2 cups of milk while whisking continuously to prevent lumps from forming. Continue cooking over medium heat for about 4-5 minutes, stirring frequently until the mixture thickens and starts to bubble gently. The desired consistency for your cheese sauce should be smooth and creamy.
Step 4: Incorporate the Cheeses
Remove the saucepan from the heat and stir in 1 cup each of shredded cheddar cheese and Monterey Jack cheese. Mix thoroughly until the cheeses have completely melted and the sauce is smooth, creating a silky texture for your cheese sauce that’s perfect for fries.
Step 5: Adjust the Consistency
If the cheese sauce seems too thick, you can gradually whisk in a bit more milk, a tablespoon at a time, until it reaches your desired creaminess. This step ensures your cheese sauce clings beautifully to fries or nachos, enhancing every bite.
Step 6: Season to Taste
Finally, season your Ultimate Cheese Sauce with salt and pepper to taste. Feel free to add any additional spices you enjoy, like paprika or cayenne, for an extra kick. Stir well to combine, ensuring each flavor shines through in this delicious cheese sauce.
Step 7: Serve Immediately
Serve your cheese sauce right away, drizzling it over hot crispy fries or alongside nachos. For an extra touch, consider garnishing with fresh herbs or toppings like crispy bacon bits or sliced jalapeños. Enjoy the richness and warmth of your home-cooked cheese sauce!
