To bake enchiladas, the typical recommended time is about 20 minutes in an oven preheated to 350°F (175°C). This duration allows the enchiladas to cook through, the cheese to melt, and the tortillas to become slightly crispy on the edges

. Here are some details from various recipes:

• Bake uncovered at 350°F for about 20 minutes until cooked through and cheese is melted and bubbly

• Some recipes suggest baking for 20 to 30 minutes at 350°F, depending on the filling and sauce

• If enchiladas are assembled cold or frozen, baking time may increase to 40-50 minutes uncovered, or bake covered for 20 minutes then uncovered for 20 minutes if frozen

• Baking at 375°F for 20-25 minutes is also common for beef enchiladas

In summary, the standard baking time for enchiladas at 350°F is around 20 minutes, with slight variations depending on the recipe and whether the enchiladas are fresh, cold, or frozen.
