1. 1. Preheat your oven to 375°F.

2. 2. In a large skillet, heat 2 tablespoon of olive oil over medium heat. Add the diced onion and minced garlic, and sauté until they become soft and fragrant. Next, toss in the ground beef, followed by 1 teaspoon of salt, 1/2 teaspoon of black pepper, and 1/2 teaspoon of paprika. Cook this mixture until the beef is browned and crumbled nicely.

3. 3. In a large mixing bowl, combine the diced potatoes with 1 cup of ranch dressing. Toss them together until each piece is thoroughly coated in that creamy goodness.

4. 4. Grease your baking dish and begin layering. Start with half of the ranch-coated potatoes, followed by spreading the cooked beef mixture evenly over this layer, and finally, top with the remaining potatoes.

5. 5. Sprinkle 1 cup of shredded cheddar cheese and 1 cup of crispy bacon bits over the final layer of potatoes.

6. 6. Cover your dish with foil and bake it for 35 minutes. After that, remove the foil and allow it to bake for an additional 15 minutes, or until the cheese is bubbly and has turned golden brown.

7. 7. As you pull your masterpiece from the oven, sprinkle with chopped green onions for a fresh touch. Serve hot.
