I love preparing this healthy veggie egg casserole with hashbrowns when I want a hearty and nourishing breakfast that still feels light and wholesome. The crispy hashbrown base creates a satisfying foundation, while the eggs and colorful vegetables bake together into a soft, flavorful filling. I often make this casserole for weekend brunch, family breakfasts, or even meal prep for busy mornings because it reheats beautifully and stays delicious for days.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
3 cups grated potatoes or frozen hashbrowns
1 tablespoon avocado oil
1 teaspoon sea salt
2 garlic cloves, minced
1 small onion, diced
1 cup mushrooms, sliced
1 bell pepper, diced
2 cups fresh spinach
8 large eggs
1/4 cup full-fat coconut milk or cream
1/2 cup shredded cheddar cheese (optional)
1/2 teaspoon black pepper
Directions
I start by preheating my oven to 375°F (190°C) and lightly greasing a 9×9-inch baking dish so the casserole releases easily after baking.
In a bowl, I toss the grated potatoes or frozen hashbrowns with avocado oil and half of the sea salt. I press the mixture firmly into the bottom of the baking dish to form an even crust.
I bake the hashbrown crust for about 20 minutes until it begins turning lightly golden and slightly crisp.
While the crust bakes, I heat a skillet over medium heat and sauté the diced onion and minced garlic for about 2–3 minutes until fragrant. I add the mushrooms and bell pepper and cook them for another 3–4 minutes until they soften.
Next, I stir in the spinach and cook it just until wilted, then I remove the pan from the heat.
In a mixing bowl, I whisk together the eggs, coconut milk, remaining sea salt, and black pepper until smooth.
I spread the cooked vegetable mixture evenly over the baked hashbrown crust. Then I pour the egg mixture over the vegetables and sprinkle shredded cheddar cheese on top if I decide to include it.
I return the dish to the oven and bake for 25–30 minutes until the eggs are fully set and the top becomes lightly golden. I let the casserole cool slightly before slicing and serving.

Variations
I often like to change this casserole depending on what vegetables I have available. Sometimes I add zucchini, broccoli, or cherry tomatoes for extra color and flavor.
When I want more protein, I mix in cooked turkey sausage or diced chicken. For a dairy-free version, I simply skip the cheddar cheese and keep the coconut milk for creaminess.
I also enjoy experimenting with herbs and spices. Fresh parsley, basil, smoked paprika, or a pinch of chili flakes can easily transform the flavor of the dish.
Storage/Reheating
I store leftover casserole in an airtight container in the refrigerator for up to 4 days. I like slicing it into individual portions so it is easy to grab for quick breakfasts.
For reheating, I warm a slice in the microwave for about 1–2 minutes until heated through. If I want the hashbrown crust to stay a little crisp, I reheat it in the oven at 350°F (175°C) for about 10 minutes.
This casserole also freezes well. I wrap individual portions tightly and freeze them for up to 2 months. When I want to eat one, I thaw it overnight in the refrigerator and reheat it normally.
FAQs
Can I use frozen hashbrowns instead of fresh potatoes?
Yes, I often use frozen hashbrowns when I want to save time. I simply thaw them slightly and press them into the baking dish to form the crust.
How do I know when the casserole is fully cooked?
I check the center of the casserole. When the eggs are set and no longer runny, and the top is lightly golden, the casserole is ready.
Can I make this casserole ahead of time?
Yes, I frequently prepare it the night before and store it in the refrigerator. In the morning, I bake it fresh or reheat pre-baked portions.
What other vegetables can I add?
I like adding zucchini, broccoli, asparagus, or tomatoes. Many vegetables work well as long as I sauté them first to remove excess moisture.
Is this casserole gluten-free?
Yes, the recipe is naturally gluten-free since it uses potatoes instead of flour-based ingredients.
Conclusion
I enjoy making this healthy veggie egg casserole with hashbrowns because it is simple, satisfying, and packed with nutritious ingredients. The crispy potato base, flavorful vegetables, and fluffy eggs create a balanced dish that works perfectly for breakfast, brunch, or meal prep. I find it to be one of those dependable recipes that I can easily customize while still delivering a comforting and delicious result every time.
