Equipment

  • 1 large skillet for sautéing vegetables
  • 1 Baking Dish (approximately 9x13 inches)
  • 1 Blender or Food Processor (for blending tofu mixture)
  • Measuring Cups and Spoons
  • Knife & Cutting Board

Ingredients
  

  • 1 Block 14 oz Firm tofu
  • 2 tbsp Olive oil
  • 1 Medium Onion diced
  • 1 Medium Bell pepper diced
  • 1 Cup Mushrooms sliced
  • 2 Cups Spinach fresh
  • 1/2 Cup Unsweetened almond milk or any plant milk
  • 1/2 tsp Garlic powder
  • 1/2 tsp Turmeric
  • 1/4 tsp Black salt optional, for egg flavor
  • 1-2 Cups Stale bread torn into chunks
  • 1/2 Cup Plant-based protein tempeh, chickpeas, or vegan sausage
  • Salt and pepper to taste
  • Nutritional yeast optional, for cheesy flavor

Instructions
 

  • Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking dish.
  • Sauté the vegetables: In a large skillet, heat olive oil over medium heat. Add the diced onions, bell peppers, and mushrooms.
    Sauté for 5-7 minutes, until softened. Add the spinach and cook until wilted, about 2-3 minutes. Remove from heat and set aside.
  • Prepare the tofu base: In a blender or food processor, blend the tofu, almond milk, garlic powder, turmeric, black salt (if using), and pepper until smooth.
  • Assemble the casserole: In a large mixing bowl, combine the sautéed vegetables, torn bread chunks, and plant-based protein.
    Pour the tofu mixture over the top and stir gently to coat all ingredients.
  • Bake: Transfer the mixture into the prepared baking dish and spread evenly. Bake in the preheated oven for 35-40 minutes, until the top is golden and firm.
  • Serve: Allow the casserole to cool for a few minutes before slicing and serving. Garnish with fresh herbs or vegan cheese if desired.

Notes

  • Customize with your favorite vegetables: You can add zucchini, tomatoes, or sweet potatoes for extra flavor and nutrients.
  • Use stale bread: Day-old or slightly dry bread works best as it absorbs the tofu mixture and helps bind the casserole together.
  • Make ahead: Assemble the casserole the night before and refrigerate overnight. Simply bake it in the morning for an easy, stress-free breakfast.
  • Make it gluten-free: Use gluten-free bread for a completely gluten-free casserole.
  • Add spice: For an extra kick, you can add chili flakes or hot sauce to the tofu mixture.
