To cook nachos in the oven, the typical baking time ranges from about 3 to 15 minutes depending on the temperature and toppings used:

• At 350°F (175°C), bake the nachos for 3 minutes initially with just a layer of cheese to create a "cheese barrier," then add other toppings and bake for an additional 5-7 minutes until the cheese is fully melted and everything is heated through

• Alternatively, baking at 375-400°F (190-200°C) usually takes about 8-15 minutes to melt the cheese and warm the toppings, with some recipes recommending around 10 minutes for fully melted, bubbly cheese without burning the chips

• Some sources suggest baking at 400°F for about 10 minutes until the cheese is melted and the chips are slightly golden

• A common approach is to start checking at 3 minutes and remove the nachos once the cheese is nicely melted and toppings are heated, usually within 10 minutes total baking time

In summary, the best practice is to bake nachos at around 350-400°F for approximately 8-10 minutes, adjusting based on your oven and toppings, ensuring the cheese melts well without burning the chips. Starting with a short bake with cheese only and then adding toppings can help keep chips crispy

. Basic cooking guideline:

• Preheat oven to 350-400°F (175-200°C)
• Spread chips on a baking sheet
• Add a layer of shredded cheese and bake 3-5 minutes
• Add toppings and more cheese if desired
• Bake another 5-7 minutes until cheese is melted and toppings are hot
• Serve immediately for best texture

This method balances melted cheese and crispy chips for ideal nachos.
