How to Make Vegan Breakfast Casserole with Hash Browns
-
Thaw the hash browns slightly and grease a 9×13 baking pan. This ensures your casserole cooks evenly and doesn’t stick while baking.
-
Sauté the onion and garlic in a pot with vegan butter over medium heat for about 3 minutes until softened and fragrant. The aroma is heavenly!
-
Add the diced zucchini, vegan sausage, sliced mushrooms, and chopped red pepper. Cook for 5-6 minutes until the veggies soften and bring their flavors to life.

Stir in the flour and cook for 2-3 minutes to remove the raw taste while allowing it to combine with the veggie mixture nicely.
-
Gradually pour in the plant milk, vegetable broth, vegan cheese, and nutritional yeast. Stir well and simmer for 8-10 minutes until the mixture thickens into a creamy delight.
-
Preheat the oven to 350°F (175°C). This step is essential for achieving that perfect golden brown crust.
-
Mix the thawed hash browns into the cheese mixture and pour it all into the greased baking pan. Cover it with foil to keep moisture in while it bakes.
-
Bake for 35 minutes, then remove the foil and bake for an additional 25 minutes until golden brown. For a crispy finish, optionally broil for a minute or two, watching closely to prevent burning.
