Slowly pour in whole milk while whisking constantly to prevent lumps. Bring mixture to a simmer, stirring often to prevent sticking. Let simmer for 4-5 minutes until thickened to gravy consistency. Season with salt and black pepper to taste.

Bake at 350°F for 25-30 minutes until tater tots are hot, crispy, and golden. Let casserole rest for 10 minutes to set before serving. Garnish with chopped green onions if desired and serve hot.
