Make Vegan Breakfast Casserole: A Simple Method

This simple, step-by-step guide will help you create a mouth-watering Vegan Breakfast Casserole that everyone will love!
Step 1: Preheat Your Oven
Start by preheating your oven to 375°F (190°C). This ensures your casserole will bake evenly and come out perfectly golden.
Step 2: Prepare the Vegetables
In a large mixing bowl, combine the diced onion, red bell pepper, and green bell pepper. This colorful mix not only adds flavor but also makes your casserole visually appealing.
Step 3: Cook the Vegan Sausage
In a skillet over medium heat, cook the crumbled vegan sausage until it’s browned and heated through. This will take about 5-7 minutes. Once cooked, remove from heat and set aside.
Step 4: Combine the Ingredients
In the large mixing bowl, add the frozen shredded hash browns, cooked vegan sausage, and sautéed vegetables. Sprinkle in the Italian seasoning, garlic powder, onion powder, and paprika. Stir well to combine all the ingredients.
Step 5: Create the “Egg” Mixture
In another bowl, whisk together the vegan egg substitute, all-purpose flour, baking powder, and a pinch of kosher salt until smooth. This mixture will give your casserole a fluffy texture.
Step 6: Mix Everything Together
Pour the “egg” mixture over the hash brown and veggie mixture. Add the shredded vegan cheddar cheese and stir until everything is well combined.
Step 7: Transfer to Baking Dish
Grease your 9×13 inch baking dish lightly with oil. Pour the combined mixture into the dish, spreading it evenly with a spatula.
Step 8: Bake to Perfection
Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the casserole is set and lightly browned on top. You can check for doneness by inserting a knife into the center; it should come out clean.
Step 9: Garnish and Serve
Once baked, remove the casserole from the oven and allow it to cool for a few minutes. Garnish with freshly chopped parsley or green onions before serving. Slice into squares and enjoy!
Nutrition-Minded Tweaks

To make this Vegan Breakfast Casserole even healthier, consider the following tweaks:
- Swap the Vegan Sausage: Use a low-fat version or homemade crumbles made from lentils or chickpeas.
- Add More Veggies: Incorporate spinach, mushrooms, or zucchini for additional nutrients.
- Use Whole Wheat Flour: Substitute all-purpose flour with whole wheat flour for added fiber.
- Reduce the Cheese: Cut back on vegan cheese or use a low-calorie alternative.
Pitfalls & How to Prevent Them
While making your Vegan Breakfast Casserole, keep these common pitfalls in mind:
- Overcooking: Keep an eye on the casserole as it bakes. Every oven is different, so check for doneness a few minutes early.
- Too Watery: Ensure your vegetables are diced finely and drained if necessary to avoid excess moisture.
- Not Enough Flavor: Adjust the seasonings according to your taste. Feel free to add more spices if you prefer a bolder flavor.
Save for Later: Storage Tips
This Vegan Breakfast Casserole is perfect for meal prep or leftovers. Here are some storage tips to keep it fresh:
- Refrigerate: Store any leftovers in an airtight container in the refrigerator for up to 5 days.
- Freeze: You can freeze the casserole before or after baking. Wrap it tightly in plastic wrap and foil for up to 3 months.
- Reheat: To reheat, simply pop it in the oven at 350°F (175°C) until warmed through, or microwave individual portions.
