Preheat the Oven: Start by preheating your oven to 400°F (200°C). This ensures your potatoes will develop that delightful crispy skin.
Prepare Potatoes: Scrub the russet potatoes clean and then pat them dry. Prick each potato with a fork, rub with olive oil, and sprinkle generously with salt and pepper.
Bake Potatoes: Place the potatoes directly on the oven rack and bake for about 45–55 minutes, or until they are tender inside and have a beautifully crispy exterior.
Cook Taco Filling: While the potatoes are baking, heat a skillet over medium heat. Add the ground beef or turkey, cooking until browned. Drain any excess fat.
Season the Meat: Stir in the taco seasoning and water, then let it simmer for 5 minutes. If you're using black beans or corn, add them at this stage for extra flavor.
Prepare Potatoes for Filling: When the potatoes are done baking, remove them from the oven. Carefully slice them open and fluff the insides gently with a fork.
Load the Potatoes: Spoon the taco meat into each potato, then top generously with shredded cheese. You can return the potatoes to the oven for 3–5 minutes if you like melty cheese!
Finish with Toppings: Finally, add your desired toppings like sour cream, salsa, diced avocado, green onions, cilantro, and jalapeños.
