Directions

Step 1

Peel and dice the potatoes into evenly sized chunks. Place them in a large pot, cover with water, and add 1 teaspoon of salt.

Step 2

Bring the pot of potatoes to a boil, reduce the heat to simmer, and cook for 10–12 minutes, or until the potatoes are fork-tender. Drain and set aside.

While the potatoes cook, preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish.

Step 4

In a skillet over medium heat, cook the ground beef and diced onion until the beef is browned and fully cooked. Drain any excess grease.

Step 5

Add the taco seasoning, tomato sauce, and frozen corn to the skillet. Stir well and let the mixture simmer for 2–3 minutes. Remove from heat.

Step 6

Mash the cooked potatoes with the butter, milk, remaining 1 teaspoon of salt, and sour cream until smooth and creamy.

Step 7

Spread the ground beef mixture evenly across the bottom of the greased baking dish.

Step 8

Spoon the mashed potatoes over the beef layer and spread them evenly using a spatula.

Step 9

Sprinkle the shredded cheddar cheese on top of the mashed potato layer.

Step 10

Bake in the preheated oven for 20 minutes, or until the cheese is melted and bubbly.

Step 11

Remove the casserole from the oven and let it rest for 5 minutes.

Step 12

Garnish the casserole with sliced green onions and optional black olives before serving.

Step 13

Serve warm, and enjoy your Taco Mashed Potato Casserole!
