So... I tried a new recipe called Cheddar-Mashed Potato Casserole from Kraft Foods website, of which I am a member. I think my recipe turned out delicious, even though I had to improvise with what I had.
...and here is the original recipe:
Cheddar-Mashed Potato Casserole (from Kraft Foods website)
2 lb. Yukon gold potatoes (about 6), peeled, quartered
2 Tbsp. Butter
1/2 cup BREAKSTONE'S or KNUDSEN Sour Cream
1 cup KRAFT Shredded Cheddar Cheese
6 slices OSCAR MAYER Bacon, cooked, crumbled
1. Cook potatoes in boiling water in large saucepan 20 min. or until tender; drain. Return to pan.
2. Heat oven to 350ºF. Add butter and sour cream to potatoes; mash until smooth. Spoon half into 1-1/2-qt. casserole; cover with layers of cheese, remaining potato mixture and bacon.
3. Bake 30 to 35 min. or until heated through.
