# Instructions:

01 - Turn oven on to 350°F. Stir thawed potatoes, melted butter, shredded cheese, and sour cream together in a big bowl.
02 - Cook garlic and onions in butter until softened. Add flour and spices, then whisk in milk and broth to make a creamy sauce.
03 - Mix the creamy sauce into the potato mixture and transfer it all into a greased 9x13-inch pan.
04 - Put the casserole in the oven and bake for 45 to 50 minutes until it's bubbling nicely.
05 - Bring the oil to 350°F. Fry onion slices in small batches for 2-5 minutes until crispy and golden. Let them drain and sprinkle with salt.
06 - Spread crispy onions over the hot casserole and dig in right away.

# Notes:

01 - Feel free to prep everything ahead, but save the onions for the last minute.
02 - Keep the oil at 350°F for every batch of onions you fry.
