A comforting dish combining tender potatoes and green beans in a creamy, flavorful sauce.
Boil the potatoes in a large pot of water until they are tender when pierced with a fork.
Cut the potatoes into even-sized pieces to ensure they cook evenly.
Cook the green beans according to the package instructions, then drain them.
If using fresh green beans, blanch them in boiling water for 3-4 minutes.
In a saucepan, melt the butter over medium heat, then stir in the flour, salt, pepper, and thyme to form a roux.
Stir constantly to prevent the roux from burning.
Gradually add the milk to the roux, whisking continuously until the sauce thickens and comes to a gentle boil.
Warm the milk slightly before adding to prevent lumps.
Combine the cooked potatoes and green beans in a serving bowl, then pour the sauce over them and mix gently to coat.
Garnish with fresh parsley or a sprinkle of paprika for added color.
