cooking spray
12 potatoes, peeled and thinly sliced
2 onions, thinly sliced
salt and ground black pepper to taste
75 g non-dairy butter
40 g all-purpose flour
720 ml vegetable broth
1 pinch paprika, or to taste
Step 1
Preheat the oven to 175°C (350°F) and grease two 23x33 cm (9x13 inch) baking dishes with cooking spray.
Step 2
Layer the sliced potatoes and onions in the prepared baking dishes, seasoning each layer with salt and pepper.
Step 3
In a medium saucepan over medium heat, melt the non-dairy butter. Stir in the flour until well blended. Gradually whisk in the vegetable broth, stirring constantly until the sauce boils and thickens. Pour the sauce over the potatoes and onions, and sprinkle paprika over the top.
Step 4
Bake in the preheated oven until the potatoes are tender and golden brown, about 50 minutes.
