How Long to Cook Mexican Casserole in the Oven
Proper cooking time can significantly affect your casserole’s taste and texture. Here, we’ll guide you through cooking times based on different oven temperatures.
Cooking at 350F

Cooking at 375F
If you opt for a slightly higher temperature of 375F, aim for a cooking duration of 20 to 25 minutes. The higher heat can help achieve a crispy top layer, which many find desirable.
Adjustments for Different Casserole Versions
The cooking time can vary depending on the specific recipe you choose. Whether you’re making adjustments for dietary preferences or ingredient availability, here are some guidelines:
Using Chicken Instead of Beef
Switching out ground beef for chicken can affect the cooking times. When using chicken, you might want to reduce the baking time by a few minutes to ensure the meat remains moist.
