Vegan Breakfast Casserole Recipe
Introduction
This Vegan Breakfast Casserole is a hearty and flavorful way to start your day. Packed with tofu, vegetables, and savory spices, it offers a satisfying plant-based alternative to traditional egg casseroles. Perfect for meal prep or a cozy weekend breakfast.

Ingredients
- 2 16-ounce (450 g) blocks silken tofu (I use Nasoya)
- 2/3 cup (51 g) nutritional yeast
- 1/3 cup (39 g) chickpea/garbanzo bean flour
- 1/4 teaspoon ground turmeric
- 1/2 teaspoon salt
- Black pepper, to taste
- 10 ounces (280 g) frozen hashbrowns (no need to thaw)
- 1/2 red bell pepper, diced
- 1/2 yellow onion, diced (or 1 teaspoon onion powder)
- 3 cloves garlic, minced (or 1/2 teaspoon garlic powder)
- 4 cremini mushrooms, sliced
- 4 ounces (110 g) frozen spinach, thawed and squeezed
Instructions
- Step 1: Preheat the oven to 350°F (175°C) and line or spray a 9×9-inch baking tray.
- Step 2: Add the tofu, nutritional yeast, chickpea flour, turmeric, salt, and black pepper to a high-speed blender or food processor. Blend until the mixture is thick and creamy, about 45 to 60 seconds. Use a tamper if your blender has one for easier mixing.
- Step 3: Evenly sprinkle the hashbrowns across the base of the prepared baking tray. Add the diced red bell pepper, onion, garlic, mushrooms, and thawed spinach over the hashbrowns.
- Step 4: Pour the blended tofu mixture over the vegetables and hashbrowns. Use a spatula to mix everything together gently, ensuring the vegetables are evenly distributed. Smooth out the top with the spatula.
- Step 5: Bake on the middle rack of the oven for 45 to 47 minutes, or until the top is evenly browned and the casserole feels firm to the touch.
- Step 6: Let the casserole sit for 5 minutes after baking. Slice and serve warm. Enjoy!
Tips & Variations
- For extra flavor, add smoked paprika or a splash of soy sauce to the tofu mixture before blending.
- Feel free to swap out the vegetables for ones you prefer, such as zucchini, kale, or cherry tomatoes.
- If you don’t have silken tofu, blend firm tofu with a bit of plant milk to achieve a creamy texture.
- Use fresh spinach instead of frozen, just sauté it lightly before adding to the casserole.
Storage
Store leftover casserole in an airtight container in the refrigerator for up to 7 days. To reheat, warm individual portions in the microwave for 1 to 2 minutes or place in a preheated oven at 350°F (175°C) for 10-15 minutes until heated through.

FAQs
Can I make this casserole ahead of time?
Yes! You can prepare the casserole fully and refrigerate it before baking. When ready to eat, bake as directed, adding a few extra minutes if baking straight from the fridge.
Is chickpea flour necessary?
Chickpea flour helps bind the casserole and adds a subtle flavor, but you can substitute with other gluten-free flours like oat or rice flour if needed. The texture may vary slightly.

- 3 cloves garlic, minced (or 1/2 teaspoon garlic powder)

Instructions
- Preheat Oven and Prepare Tray: Preheat your oven to 350°F (175°C) and line or lightly spray a 9×9-inch baking tray to prevent sticking.
- Blend Base Mixture: Combine the silken tofu, nutritional yeast, chickpea flour, turmeric, salt, and black pepper in a high-speed blender or food processor. Blend for 45 to 60 seconds until the mixture is thick, creamy, and smooth.
- Assemble Casserole: Evenly distribute the frozen hashbrowns across the base of the prepared baking tray.

Use a spatula to mix and incorporate everything well, ensuring an even distribution and smoothing out the top for an even bake.

Notes
- You can substitute the red bell pepper and mushrooms with other vegetables like zucchini, broccoli, or kale depending on your preference.
- If you don’t have fresh garlic or onion, garlic powder and onion powder are acceptable alternatives.
- Do not thaw hashbrowns before using; they bake well frozen and help create a crisp texture.
- Use a high-speed blender or food processor for best results; a regular blender may require a tamper or stopping to scrape down the sides.
- Leftover casserole can be reheated in the microwave or oven and makes excellent packed breakfast for busy days.
