HOW TO MAKE VEGETARIAN MEXICAN CASSEROLE

Below is a step-by-step guide to assembling and baking this delightful casserole. Follow each stage carefully to ensure every layer is perfectly seasoned and the final dish is bubbly, cheesy, and satisfying.

1. Preheat your oven to 375°F (190°C) to ensure it’s evenly heated before baking the casserole.

2. In a large skillet, heat the olive oil over medium heat until shimmering, which helps prevent sticking and allows vegetables to sauté gently.

3. Add the chopped onion and cook until it becomes translucent, about 5 minutes, stirring occasionally to avoid burning.

4. Stir in the minced garlic, diced red bell pepper, diced yellow bell pepper, and chopped zucchini. Cook for another 5 minutes, or until the vegetables are tender but still vibrant in color.

5. Add the corn kernels, drained black beans, drained pinto beans, ground cumin, chili powder, and smoked paprika. Stir constantly until the spices are evenly distributed and the beans are warmed through.

6. Pour in the diced tomatoes with green chilies and the salsa. Mix thoroughly, then season with salt and pepper to taste, ensuring a balanced and lively flavor.

7. Remove the skillet from heat and stir in the cooked brown rice and one cup of the shredded cheese until everything is well combined.

8. Layer half of the tortilla strips at the bottom of a greased 9×13-inch baking dish, forming a sturdy base that will absorb the delicious juices.

9. Spread half of the vegetable and rice mixture evenly over the tortilla layer, ensuring each corner of the dish gets a good share.

10. Repeat the layering process with the remaining tortilla strips and the rest of the vegetable mixture, creating two cohesive layers.

11. Top the casserole with the remaining one cup of cheese, distributing it evenly to achieve that signature melty crust.

12. Cover the dish with foil and bake in the preheated oven for 25 minutes, allowing all ingredients to meld and the cheese to soften.

13. Remove the foil and bake for an additional 10 minutes, or until the cheese is fully melted and bubbly, with lightly golden edges.

14. Garnish with chopped fresh cilantro right before serving to add a pop of color and a burst of herbal freshness.

SERVING SUGGESTIONS FOR VEGETARIAN MEXICAN CASSEROLE

When it’s time to serve, this casserole truly shines as a hearty centerpiece. Whether you’re hosting a casual dinner or enjoying a family meal, presentation and complementary sides can elevate the experience. Here are some ideas to make each serving feel extra special:

• Fresh guacamole: Dollop a scoop of creamy, lime-infused guacamole on each portion. The cool avocado blends beautifully with the warm layers of cheese and spices, adding both color and richness.

• Zesty lime wedges: Offer lime wedges on the side for guests to squeeze over their casserole. The tangy citrus cuts through the richness and brings a bright, refreshing contrast.

• Creamy sour cream: Serve with a side of sour cream for a smooth, slightly tangy topping. Swirl a tablespoon on top of each serving to mellow out any extra spice and add a silky texture.

• Crispy tortilla chips: Provide a handful of tortilla chips for scooping or crumbling. Their crunch pairs perfectly with the soft, cheesy layers, creating a delightful textural contrast.

HOW TO STORE VEGETARIAN MEXICAN CASSEROLE

After enjoying your initial feast, you’ll want to keep any leftovers fresh and delicious. Proper storage ensures that each reheated serving tastes just as good as the first. Follow these methods to maintain flavor and texture:

• Refrigeration: Allow the casserole to cool to room temperature, then place it in an airtight container or cover the baking dish tightly with foil. Store in the refrigerator for up to 4 days, reheating individual portions in the microwave or oven.

• Freezing: For longer-term storage, slice the cooled casserole into portions and wrap each one in plastic wrap, then place in a freezer-safe bag. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.

• Oven reheating: To maintain that fresh-baked texture, preheat the oven to 350°F (175°C). Place the casserole (covered) on a baking sheet and heat for 15–20 minutes, or until warmed through. Remove the cover in the last 5 minutes for a melty cheese top.

• Meal prep jars: Layer individual servings in mason jars for grab-and-go lunches. Start with rice and beans, then veggies, cheese, and garnish. Store in the fridge for up to 3 days, and reheat with the lid off in the microwave.
