1-First, preheat the oven to 400°F (205°C) and line a baking sheet with foil. This helps with cleanup and ensures even baking.

2-Next, wash and dry the potatoes, poke holes in them with a fork, spray with olive oil, then season with salt and pepper. Pop them in the oven for about 45 minutes to bake until tender.

3-While the potatoes are baking, brown the ground beef and diced onion in a skillet over medium heat, then drain the excess grease. Add taco seasoning and water, simmering for a few minutes until it’s all mixed well.

4-In a saucepan over medium-low heat, melt the processed cheese, shredded pepper jack, diced chilies, and evaporated milk, stirring until smooth. This cheese sauce will tie everything together perfectly.

5-After the initial bake, switch the oven to low broil and bake the potatoes for another 15 minutes to crisp the skins. Once done, cut them open, fluff the insides, and season again if needed.

6-Finally, top each potato with the cheese sauce, taco meat, extra shredded cheeses if you like, and add-ons such as diced tomatoes, sliced jalapeños, sour cream, and chopped cilantro. The whole process takes about 15 minutes to prepare, with a total cook time of around 1 hour.
