In a large skillet, crumble and brown the sausage, then drain off the grease.
2 16oz pkg ground sausage
Cut potatoes into fat 1/4" slices and boil for 10-15 minutes. Take care not to over cook the potatoes. They should be a little hard as they will continue to cook when you bake the casserole.
3 lb Yukon Gold potatoes
Then, rinse them with cold water so that you can easily handle the slices.
In a mixing bowl, combine the cream soup with the Worcestershire sauce and milk, then whisk together. Season with dried thyme, salt, and pepper to taste.
2 10.5 oz cans cream of potato soup, 1½ cups milk, 2 teaspoons Worcestershire sauce, salt, black pepper, 1/2 teaspoon dried thyme
Butter a 9×13 casserole dish. (Alternatively, you can use (2) 8x8 or 9x9 pans).
Begin layering the ingredients in this order: a little sauce on bottom, half the sliced potatoes, half the sausage, half the cheese, and repeat until dish is full, ending with sauce on the top.I like to add a little bit of extra salt and pepper to the layers as well, but that's a personal preference. 2 cups cheddar cheese, shredded
Crush the crackers and sprinkle them over the top.
buttery crackers such as Ritz
Drizzle melted butter over the top, then finish off with a bit more cheese.
2 tablespoons butter, 3/4 cup cheddar cheese, shredded
Cover with tinfoil and bake at 350-degrees F for 45-60 minutes until bubbly.
Remove the tinfoil and bake another 5-8 minutes to allow top to brown.
