Potatoes O'Brien Au Gratin Recipe

This is my homemade version of a popular dish that typically uses the store bought Potatoes O'Brien, which is often hard to find in the stores close to big holidays. With this recipe you can make it all from scratch and it's so easy and less expensive.

So here is the recipe with all my helpful notes.

2 and 1/2 medium size Russet Potatoes, scrubbed and grated using the larger grater holes. Then rinse with cold water and drain. Yes, leave the peels on!
1/4 c. EACH of chopped Sweet Onion, and 3 kinds of Peppers (orange, red, yellow and/or green)So 1 c. total.
1/2 contents of 10.5 oz. size Cream of Chicken Soup (Save the rest to make this again!)
1/2 contents of small (8 oz.) Sour Cream
1 c. shredded Cheddar Cheese, divided into 2/3 c. in dish + 1/3 c. on top per recipe
Salt & Pepper

Preheat oven to 375 degrees. Grease a 8" x 8" baking dish.
In medium bowl, mix sour cream and soup. Add 2/3 c. of the cheese and mix well.
Add potatoes, onion and peppers. Mix well.
Pour in greased dish, sprinkle lightly with salt and pepper, and bake for 30 minutes, uncovered.
Remove from oven and sprinkle remaining 1/3 c. cheese over the top. Bake uncovered another 30 minutes.

Serves 6. Leftovers freeze well, if needed.
