How to Make Cheesy Potato And Onion Casserole

Preheat oven to 375°F (190°C).
Peel and thinly slice 2 large onions.
Peel and thinly slice 2 lbs potatoes.
Core and slice 2 medium tomatoes.
In a greased 9x13 inch baking dish, layer potatoes, onions, and tomatoes. Season each layer generously with salt, pepper, and 1 tbsp dried thyme.
Dot the top with 2 tbsp margarine.
Cover the dish with foil and bake for 50-60 minutes, or until potatoes are tender.
While potatoes bake, prepare the cheese sauce: Melt 4 tbsp butter in a saucepan. Whisk in 4 tbsp all-purpose flour until smooth. Gradually whisk in 3 cups milk until smooth and thickened. Stir in 2 cups shredded cheddar cheese, 1 tbsp Dijon mustard, and salt and pepper to taste.
Remove the casserole from the oven, pour the cheese sauce evenly over the vegetables, and return to the oven uncovered for 15-20 minutes, or until golden brown and bubbly.
