Loaded Mashed Potato Casserole is the most delicious way to repurpose up to 4 cups of leftover mashed potatoes. It's loaded with bacon, cheese, sour cream, two kinds of onion, and topped with cheese crackers for good measure.
Preheat oven to 350 degrees F. Spray large casserole dish with nonstick spray. In small bowl, stir crackers and butter until well combined.
If mashed potatoes are cold, place in a large microwave-safe bowl and microwave 60 to 90 seconds to soften. Add sour cream, garlic powder and pepper to potatoes; stir until well combined.
Reserve 2 tablespoons each bacon and cheese. Add remaining bacon and cheese to potatoes, along with red onion, green onion and parsley; stir until well combined.
Transfer mixture to prepared casserole dish and sprinkle with cracker mixture and reserved bacon and cheese. Bake 25 to 30 minutes or until heated through.
