How to Store or Freeze This Casserole
Allow the Mexican casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
Transfer the casserole to an airtight container. If you prefer, you can also use a baking dish with a tight-fitting lid.
For short-term storage, place the container in the refrigerator. The casserole will stay fresh for up to 4-5 days.
If you plan to store the casserole for a longer period, consider freezing it. Wrap the entire baking dish tightly with plastic wrap, followed by a layer of aluminum foil. This double layer helps prevent freezer burn.
Alternatively, you can portion the casserole into individual servings before freezing. Use freezer-safe containers or resealable plastic bags. Label each container with the date to keep track of freshness.
When ready to enjoy, thaw the frozen casserole in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor.
Reheat the casserole in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until heated through. If reheating from frozen, it may take a bit longer, around 30-35 minutes.
For a quicker option, you can also reheat individual servings in the microwave. Place the portion on a microwave-safe plate and cover it with a microwave-safe lid or another plate. Heat on high for 2-3 minutes, stirring halfway through to ensure even heating.
To keep the vegan cheese melty and delicious, you can add a fresh sprinkle of cheese on top before reheating. This will give it that freshly baked appeal.
Enjoy your reheated Mexican casserole with a side of avocado slices, a dollop of vegan sour cream, or a sprinkle of fresh cilantro for an extra burst of flavor.
How to Reheat Leftovers

- Preheat your oven to 350°F (175°C).
- Transfer the leftover Mexican casserole to an oven-safe dish.

Microwave Method:
- Place a portion of the casserole in a microwave-safe dish.
- Cover the dish with a microwave-safe lid or a damp paper towel to retain moisture.
- Heat on high for 2-3 minutes, stirring halfway through to ensure even heating. Add an extra minute if needed.
Stovetop Method:
- Heat a non-stick skillet over medium heat.

Air Fryer Method:
- Preheat your air fryer to 350°F (175°C).
- Place the casserole in an air fryer-safe dish or use aluminum foil to create a makeshift dish.
