Ingredients
2
boxes Betty Crocker™ au gratin potatoes
1 1/2
cups finely shredded sharp Cheddar cheese (6 oz)
1 1/2
cups finely shredded Monterey Jack cheese (6 oz)
1/4
cup grated Parmesan cheese
3 1/2
cups water
2
cups half-and-half
1
can (2.8 oz) French-fried onions (about 2 cups)
Preparation
Heat oven to 400°F. Spray 13x9-inch (3-quart) glass baking dish with cooking spray. Place potatoes (from au gratin potato boxes), and Cheddar, Monterey Jack and Parmesan cheeses in baking dish.
In 3-quart saucepan, heat water to boiling, stir in sauce mixes (from au gratin potato boxes) with whisk until dissolved. Stir in half-and-half. Pour over potatoes and cheese in baking dish. Bake 30 to 35 minutes or until potatoes are tender.
Stir potatoes; sprinkle with onions. Bake 5 to 7 minutes longer or until French-fried onions are golden brown. Let stand 5 minutes before serving (sauce will thicken as it stands).
