Preheat your oven to 375°F (190°C).

Peel the potatoes and chop them into small, even cubes.

Chop the onion and mince the garlic cloves.

In a large skillet over medium heat, heat the olive oil. Add the chopped onion and minced garlic, sautéing until fragrant and softened.

Toss in the ground beef along with the salt, black pepper, thyme, and paprika. Cook and break up the meat until it's browned and fully cooked.

Pour in the beef broth, giving it a good mix. Let this simmer for a few minutes so all the flavors meld together. Then, remove the skillet from heat.

In a large mixing bowl, combine your diced potatoes with the beef mixture. Gently fold in the sour cream and half of the shredded cheddar cheese until everything is beautifully mixed.

Transfer this mixture into a baking dish, spreading it evenly. Finish by sprinkling the remaining cheddar cheese on top.

Cover tightly with foil and let it bake in the preheated oven for 30 minutes.

After 30 minutes, remove the foil and continue baking for another 10 to 15 minutes, until the cheese is wonderfully melted and bubbling.

Take it out of the oven and let it rest for about 10 minutes before serving to give it the perfect texture.
