Savory Hard-Boiled Egg Spinach Breakfast Bake

There’s something deeply comforting about a warm, homemade breakfast on a slow weekend morning.

It’s a dish that doesn’t shout for attention but always leaves people asking for seconds.

This recipe is inspired by quiet Sunday mornings growing up, when the house would still be sleepy, and the only sound was the soft hum of the oven and the sizzle of breakfast in the kitchen. It’s the kind of meal my mom would make using whatever greens and eggs we had on hand—often leftover hard-boiled eggs from the week—and turn them into something hearty and satisfying.

A cross between a casserole and a crustless quiche, this breakfast bake brings together creamy eggs, vibrant spinach, and savory aromatics. It’s the perfect way to start the day whether you’re hosting brunch or just want something nourishing to meal prep for busy mornings.

INGREDIENTS YOU’LL NEED:

• 6 hard-boiled eggs, peeled and halved
• 1 tablespoon olive oil
• 1 small onion, finely chopped
• 2 garlic cloves, minced
• 6 oz fresh spinach
• 4 large eggs
• 1 cup milk of choice (dairy or non-dairy)
• 1 cup shredded mozzarella cheese
• 1/2 teaspoon salt
• 1/2 teaspoon black pepper
• 1/4 teaspoon nutmeg (optional)

HOW TO MAKE SAVORY HARD-BOILED EGG SPINACH BREAKFAST BAKE:

STEP-BY-STEP INSTRUCTIONS:

1. Preheat and prep
   Start by preheating your oven to 375°F (190°C). Lightly grease a medium-sized baking dish—something around 8×8 inches works perfectly.
2. Sauté the aromatics
   In a skillet over medium heat, warm the olive oil and toss in the chopped onion. Cook until it becomes translucent and fragrant, about 4–5 minutes. Add the minced garlic and stir for another 30 seconds.
3. Wilt the spinach
   Add the spinach to the skillet and cook down until it wilts—this should only take a couple of minutes. Don’t worry if it looks like a lot at first; spinach always reduces a ton!
4. Whisk the egg mixture
   In a separate mixing bowl, whisk together the 4 large eggs, milk, salt, pepper, and nutmeg. Stir in the shredded cheese for a little gooey richness throughout the bake.

1. Assemble the bake
   Spread the spinach mixture evenly across the bottom of your greased baking dish. Nestle the halved hard-boiled eggs into the spinach, yolk-side up. Then, gently pour the egg and milk mixture over everything, letting it settle around the ingredients.
2. Bake to golden perfection
   Slide the dish into the oven and bake for 30–35 minutes, or until the center is set and the top is just starting to turn golden. The aroma at this point is heavenly—warm eggs, bubbling cheese, and toasty edges.
3. Cool and serve
   Let the bake rest for 5–10 minutes before slicing into it. It’ll hold together better and the flavors really come through after a short rest.

HELPFUL TIPS:

• Make it dairy-free by using non-dairy milk and a plant-based cheese or simply omitting the cheese altogether.
• Bulk it up by adding diced cooked potatoes or sweet potatoes for an even heartier dish.
• Add herbs like chopped parsley, chives, or dill to the egg mixture for an extra layer of flavor.
• If your hard-boiled eggs are a bit older, this is a great way to use them up deliciously.
• This bake also tastes great at room temperature—ideal for brunch spreads or picnic-style breakfasts.
