My grandpa used to make this for Sunday dinner, and every plate was wiped clean. Just three simple ingredients come together for the ultimate cozy comfort dish.

This oven-baked brown gravy potato dish proves that simple ingredients can deliver big flavor. With just three staples, you get a rich, comforting side that tastes like it’s been slow-cooked for hours. As the potatoes bake, they absorb the savory gravy while the butter adds extra richness, creating a soft, melt-in-your-mouth texture with a thick, velvety finish.

 3-Ingredient Brown Gravy Potato Bake

Ingredients

• 3 lbs potatoes (Russet or Yukon Gold)
• 3 cans (10½ oz each) brown gravy
• 4 tbsp unsalted butter, cut into small pieces

 Instructions

1. Prep the potatoes
Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Peel and slice potatoes into thin, even rounds (about 1/8-inch thick).

2. Smooth the gravy
Pour gravy into a bowl and whisk until smooth for even layering.

3. Layer the dish
Create three layers:

• First layer: potatoes, gravy, butter
• Repeat for the second layer
• Finish with remaining potatoes, gravy, and butter on top
