Can you cook lasagna at 400 degrees in the oven?

Yes, you can cook lasagna at 400 degrees Fahrenheit in the oven. This temperature is suitable for baking lasagna, allowing it to cook through and develop a nice golden top. Typically, it may take about 25 to 30 minutes, but it's important to check for bubbling and ensure the cheese is melted and slightly browned. Always cover the lasagna with foil for the first part of cooking to prevent over-browning.
