Ingredients

1 Tablespoon Morton's Kosher salt *see note
3 lbs. Yukon Gold potatoes (chopped into 1/2 inch cubes)
1/4 cup salted butter
2/3 cup low sodium chicken broth
1/3 cup milk (whole or 2%)
3 Tablespoons flour
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1 cup full fat sour cream
3 cups sharp cheddar cheese (divided)
Salt and pepper (to taste)
3 green onions (chopped)

Instructions

Preheat oven to 375 degrees and grease a 9 x 13 inch baking dish.
Add the potatoes to a large pot of cold water salted with the tablespoon of Kosher salt. Bring the mixture to a boil and cook for 7-10 minutes or until fork tender, then drain and add to the baking dish.
Bring the chicken broth and butter to a boil in a medium sauce pan.
In a measuring cup, whisk together the milk, flour, garlic powder, and onion powder. Pour the milk mixture into the boiling broth and continue to cook, whisking constantly, until the mixture is thickened and coats the back of a spoon. Lower the heat and season to taste with salt and pepper.
Stir in sour cream and 1 1/2 cups of the cheddar until melted.
Pour the sauce over the potatoes along with most of the green onions. Top with remaining 1 1/2 cups cheese. Bake for 20 minutes or until cheese is browned and mixture is bubbly. Top with the remaining green onions before serving.

Notes

Just like salting pasta water, salting your potato water will infuse the potatoes themselves with good flavor, instead of just covering a somewhat bland potato with cheese sauce.
Salted or unsalted butter can be used for this recipe.
Substitute veggie broth to make the casserole vegetarian.
Gluten free 1 to 1 flour can be substituted for all purpose to make the dish gluten free.
Feel free to sub half the cheese for a different flavor (colby jack, pepper jack, gruyere, etc).
To make ahead of time, assemble the casserole, cover, and store in the fridge until ready to bake. Bake as usual whenever you're ready. (I recommend baking within 24 hours).
