While the water is beginning to boil, shred your block of cheese. Set aside.
8 oz Shredded Cheddar Cheese
Begin to make the roux for your sauce. Melt the butter in a medium saucepan over medium heat.
2 Tbsp Butter
Once the butter is melted, add the flour. Continue to stir and cook over medium heat for 1-2 minutes.
2 Tbsp Unbleached All-purpose Flour
After a couple of minutes, slowly whisk in your milk until incorporated well.
1 Cup Whole Milk
Add plain Greek yogurt (or sour cream) and whisk until smooth.
1/4 Cup Greek Yogurt
Cook the sauce for a couple of minutes until it begins to thicken.
Once the mixture is thick, reduce the heat to low and add the cheese. Stir constantly as the cheese begins to melt and become smooth.
Lastly, add in your salt to taste. (Feel free to omit if you are making it for littles)
1/2 tsp Sea Salt
Once the cheese is completely melted, your noodles should be done cooking around this time. Drain your noodles and immediately add them to your sauce. Mix well until all noodles are coated with that cheesy goodness.
Serve as a side dish or enjoy by itself!
