How to Make Mashed Potato Casserole

Potato Casserole

Step 1

Generously grease a 9x13-inch casserole dish with nonstick cooking spray. Preheat oven to 350°F.
Step 2

Place potatoes in a large pot and cover with cold water. Lightly salt the water and add garlic, bay leaf, and thyme. Bring to a boil over high heat, then reduce heat, partially cover, and simmer until potatoes are fork tender, about 20 minutes. Drain and let stand until potatoes steam dry, about 3 minutes. Discard bay leaf and thyme sprigs.
Step 3

Divide cooked potatoes in half. Mash half the potatoes using a potato masher until there are no lumps. Add the cream cheese, olive oil, Greek yogurt, and milk; stir until smooth. Season with black pepper, thyme, and sage. Add remaining potatoes; stir to combine. Transfer potato mixture to prepared baking dish and smooth the top.

Bread Crumb Topping

Step 1

In a small mixing bowl, combine the bread crumbs, thyme and black pepper. Sprinkle the bread crumb mixture evenly over the top of the mashed potatoes. If you would prefer the casserole without the bread crumb topping (as pictured), skip this step.
Step 2

Bake until top is golden brown and potatoes are heated through, about 35 to 40 minutes. Serve warm topped with a dollop of Greek yogurt and garnished with sliced green onion and chopped mint.
