Use a potato masher or a fork to mash the potatoes.

Step 6

Add the butter, the milk, the cheddar cheese, the garlic powder, 1/2 teaspoon of the salt, and 1/4 teaspoon of the pepper to the mashed potatoes and stir well.

While the potatoes are boiling, heat the olive oil in a large cast-iron skillet over medium-high heat until it sizzles, about 2 minutes.

Step 8

Add the onion and the carrots to the skillet and sauté until fragrant and tender, about 2-3 minutes.

Carefully spoon the mashed potatoes over the top of the ground beef mixture, spreading them out evenly.
