This cheesy potato bake takes many of our favorite comfort foods: creamy potatoes, melty cheese, rich butter and decadent sautéed onions. The flavors melt together into a delicious casserole that warms us from the inside out. Peeling and slicing the potatoes, and chopping the onions takes a little extra effort, but it is worth it for the homemade goodness that we love.
We often tuck this casserole into the oven alongside a roast for Sunday dinner and are rewarded when the whole family cleans their plates and asks for seconds. It’s definitely a favorite at our house!
