Scrub 2-4 sweet potatoes and pierce with a fork. Bake at 425℉ for 45-60 minutes and allow to cool slightly before stuffing with taco meat. Alternatively, you can make in the instant pot. To a large skillet, add oil over medium heat. Once hot, sauté diced yellow onion until translucent, about 5 minutes. Add minced garlic and sauté until fragrant, about 1 minute.
Add ground beef and season with chili powder, cumin, garlic powder, onion powder, smoked paprika, salt and pepper. Brown and crumble ground beef until no longer pink.
Stir in salsa and black beans - if using. Stir to combine and warm through for 5 minutes.
Using a butter knife, half the baked sweet potatoes and mash the flesh a bit with a fork. Top each half with a heaping scoop of meat mixture (about 1/2 cup), and top with cheese and any additional toppings. Serve and enjoy.
