Ingredients

45 grams of butter
60 grams of all-purpose flour
415 milliliters of low-sodium chicken broth
30 grams of mayonnaise
2 cloves of garlic, minced
4 grams of salt
1 gram of dried parsley
1 gram of poultry seasoning
0.5 grams of ground black pepper
60 milliliters of chopped fresh chives
5 large potatoes, peeled and thinly sliced
180 milliliters of chopped onion

Directions

Step 1
Preheat the oven to 165 degrees C (325 degrees F). Grease a 2.5-liter baking dish.
Step 2
In a saucepan over medium heat, melt the butter. Add the flour and whisk until smooth. Slowly whisk in the chicken broth, then add the mayonnaise, garlic, salt, parsley, poultry seasoning, and pepper. Cook and stir until the mixture thickens and becomes bubbly, approximately 2 minutes.
Step 3
Layer the thinly sliced potatoes and chopped onion in the prepared baking dish. Pour the creamy broth mixture over the top and cover with aluminum foil.
Step 4
Bake in the preheated oven until the potatoes are tender, approximately 1 hour and 45 minutes. Remove the foil and continue to bake until the top turns golden brown, about 15 more minutes. Sprinkle with the fresh chives before serving.
