Equipment

• Large skillet or sauté pan
• Mixing bowl
• 9×13-inch casserole dish
• Cutting board
• Chef’s knife
• Measuring cups and spoons
• Wooden spoon or spatula
• Aluminum foil (for covering casserole)
• Oven mitts

Instructions

1. Preheat and Prep:

   Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with olive oil or nonstick spray.

2. Sauté Vegetables:

   In a large skillet over medium heat, add olive oil. Once hot, add the onion and cook for 2-3 minutes until translucent.

   Add garlic, bell peppers, and carrots. Sauté for 5-7 minutes until softened.

   Stir in the broccoli and cook another 3 minutes. Remove from heat.

3. Mix Casserole Base:

   In a large mixing bowl, combine the cooked brown rice, black beans, diced tomatoes (with juices), corn, plant-based milk, nutritional yeast, smoked paprika, oregano, salt, and black pepper. Mix until evenly combined.

4. Combine Everything:

   Add the sautéed vegetables to the rice mixture. Stir well to combine.

   Taste and adjust seasoning if needed.

5. Assemble in Baking Dish:

   Spoon the mixture into your prepared casserole dish. Smooth the top with a spatula.

6. Add Topping:

   Sprinkle bread crumbs evenly over the top. For extra crunch, you can drizzle a little olive oil over the crumbs.

7. Bake:

   Cover the dish with aluminum foil and bake for 20 minutes. Remove foil and bake an additional 10-15 minutes, until the edges are bubbling and the topping is golden brown.

8. Garnish & Serve:

   Let the casserole cool for 5-10 minutes before serving. Top with fresh parsley and enjoy!

Pro Tip: For an even cheesier flavor, add an extra tablespoon of nutritional yeast to the breadcrumb topping before baking.

Tips & Variations

• Add More Protein: Stir in a cup of cooked lentils or vegan chicken pieces for a heartier casserole.
• Make It Gluten-Free: Use gluten-free bread crumbs or omit the topping altogether.
• Switch Up the Veggies: Substitute or add vegetables like zucchini, spinach, cauliflower, or mushrooms based on what’s in season or your preferences. Try the mushroom-forward twist in our Alba Clamshell Mushroom Recipes.
• Spicy Kick: Add a diced jalapeño or a pinch of red pepper flakes for heat.
• Creamy Upgrade: Swap plant milk for coconut milk or add a dollop of vegan sour cream for a richer texture.
• Meal Prep: This casserole tastes even better the next day! Cool completely, then refrigerate in an airtight container for up to 4 days. Freeze in portions for up to 2 months.
• Try Different Grains: Quinoa, farro, or a wild rice blend all work beautifully in place of brown rice.
• Make it Cheesy: Top with your favorite vegan shredded cheese before baking for extra meltiness.
• For Extra Crunch: Mix in a handful of Almond Cashew Clusters or roasted nuts to the bread crumbs before topping.
