1Preheat your oven to 375°F (190°C).
Peel and slice the 4 medium potatoes into thin rounds.
In a large pot, bring water to a boil and add the potato slices. Cook for about 5-7 minutes until slightly tender, then drain.
In a baking dish, layer half of the potato slices evenly.
Spread half of the soft cheese over the potatoes, followed by half of the shredded cheese.
Add the canned peas evenly over the cheese layer.
Pour half of the pasta sauce over the peas.
Repeat the layers with the remaining potatoes, soft cheese, shredded cheese, and pasta sauce.
Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes.
Remove the foil and bake for an additional 10-15 minutes, or until the top is golden and bubbly.
Let the casserole cool for a few minutes before serving.
