Step 1: Prepare the Taco Meat - Start by browning the beef in the Instant Pot using the sauté function. Drain excess fat, add your favorite taco seasoning, and a splash of water. Stir well, then seal the lid and set to manual high pressure for 10 minutes. Once done, perform a quick release.
Step 2: Layer the Nachos - In a large mixing bowl, combine the cooked taco meat with 1 cup of shredded cheese. Gently mix until the cheese begins to melt and combine with the meat.
Step 3: Assemble the Nachos - On a large serving platter or dish, spread out the tortilla chips evenly. Spoon the cheesy taco meat mixture over the chips, ensuring even coverage.
Step 4: Add More Cheese - Sprinkle the remaining 1 cup of shredded cheese generously over the top of the nachos.
Step 5: Melt the Cheese - If you wish to melt the cheese further, place the nachos in the oven at 350°F (175°C) for about 5-10 minutes until bubbly and golden. Alternatively, use the instant pot on the sauté setting for a couple of minutes, being cautious not to burn the bottom.
Step 6: Top and Serve - Once the cheese is melted, add dollops of sour cream and sprinkle chopped cilantro on top. Serve immediately and enjoy!
