Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

3 medium red potatoes (or 2 cups frozen hashbrowns)
2 teaspoons avocado oil (or sub olive oil)
½ teaspoon sea salt
1 tablespoon avocado oil (or sub olive oil)
3–4 garlic cloves, minced
1 cup yellow onion, diced
1 cup mushrooms, chopped
1 large bell pepper, diced
2 cups spinach
8 eggs
¼ cup full fat coconut milk (or sub cream)
¼ cup grated cheddar cheese (optional)
½ teaspoon sea salt

Directions

1. Preheat your oven to 400°F and grease a 9x9 baking dish with oil.

2. Grate the potatoes using the largest side of a cheese grater. Squeeze out as much liquid as possible using your hands. If using frozen hashbrowns, skip this step.

3. Toss the grated potatoes with oil and sea salt. Press into the prepared baking dish in an even layer. Bake for 20–25 minutes, or until the edges are golden and crispy.

4. While the crust bakes, prepare the filling.

5. Heat oil in a pan over medium heat. Add garlic, onion, mushrooms, and bell pepper. Sauté for 4–5 minutes until onions are translucent. Add spinach and cook until wilted.

6. In a mixing bowl, whisk together eggs, coconut milk, grated cheese (if using), and sea salt.

7. Remove the hashbrown crust from the oven. Spread the cooked vegetables evenly over the crust. Pour the egg mixture evenly on top.

8. Bake for 20–25 minutes, or until the eggs are fully set to your preference.

9. Serve warm with salsa, guacamole, or hot sauce if desired.

Servings: 9 servings

Prep Time: 15 minutes
Cook Time: 45–50 minutes
Total Time: Approximately 1 hour 5 minutes

Variations

Make it dairy-free by skipping the cheese entirely.

Add extra protein such as cooked turkey sausage or diced ham.

Swap vegetables based on what you have on hand, such as zucchini, broccoli, or cherry tomatoes.

Use sweet potatoes instead of red potatoes for a slightly sweeter crust.

Add fresh herbs like parsley, basil, or chives for extra flavor.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days.

To reheat, warm individual portions in the microwave for 30–60 seconds or until heated through.

You can also reheat slices in a 350°F oven for about 10 minutes to maintain the crispy crust texture.

For longer storage, freeze individual portions tightly wrapped for up to 2 months. Thaw overnight in the refrigerator before reheating.

FAQs

Can I use frozen hashbrowns instead of fresh potatoes?

Yes. Simply skip the grating and draining step and press the frozen hashbrowns directly into the baking dish.

How do I know when the casserole is fully cooked?

The center should be set and no longer jiggly. A knife inserted in the middle should come out clean.

Can I make this casserole ahead of time?

Yes. You can prepare and bake it ahead, then refrigerate and reheat when ready to serve.

Is this recipe dairy-free?

It can be. Just omit the cheese and use coconut milk instead of cream.

Can I add meat to this recipe?

Absolutely. Cooked sausage, bacon, or diced ham can be layered over the hashbrown crust before adding the egg mixture.

What other vegetables work well?

Broccoli, zucchini, asparagus, kale, or cherry tomatoes are great additions.

Can I use egg whites instead of whole eggs?

Yes. Substitute with about 2 egg whites per whole egg, though the texture may be slightly less rich.

Why do I need to squeeze the potatoes?

Removing excess moisture helps the crust become crispy rather than soggy.

Can I double this recipe?

Yes. Use a 9x13-inch baking dish and adjust the baking time slightly if needed.

Is this good for meal prep?

Definitely. It stores and reheats well, making it ideal for quick breakfasts throughout the week.
