INGREDIENTS YOU’LL NEED:

- 6 hard-boiled eggs, peeled and sliced
- 3 cups baby spinach, roughly chopped
- 1 small onion, finely diced
- 1 cup shredded cheddar cheese
- ½ cup milk
- 6 large eggs
- 2 tablespoons olive oil
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon paprika
- Salt and pepper, to taste
HOW TO MAKE Savory Hard-Boiled Egg & Spinach Breakfast Bake:
First things first: imagine your kitchen slowly filling with the smell of onions gently caramelizing and cheese melting into golden perfection — that’s the magic you’re about to create.
STEP-BY-STEP INSTRUCTIONS:
- Preheat and Prep
Start by preheating your oven to 350°F (175°C). Lightly grease a 9×9-inch baking dish with a little olive oil or cooking spray. This helps ensure the bake comes out easily and gives you those beautiful, crispy edges. - Sauté the Onion and Spinach
In a medium skillet over medium heat, warm the olive oil. Add the diced onion and cook until it’s translucent and fragrant, about 3-4 minutes. Toss in the chopped spinach and stir until it’s wilted down, another 2 minutes or so. The spinach will look like a lot at first, but it cooks down quickly — a little kitchen magic right before your eyes. - Layer the Goodness
Spread the sautéed onion and spinach mixture evenly over the bottom of your prepared baking dish. Arrange the sliced hard-boiled eggs over the spinach like you’re creating a beautiful little mosaic.

- Whisk the Eggs and Seasoning
In a mixing bowl, whisk together the fresh eggs, milk, garlic powder, onion powder, paprika, salt, and pepper. Keep whisking until it’s all combined and slightly frothy — this helps create a light, fluffy texture once baked. - Assemble and Top
Pour the egg mixture carefully over the hard-boiled eggs and spinach. Sprinkle the shredded cheddar cheese evenly across the top. It might not look like much at this point, but just wait — the oven is about to work its magic. - Bake to Perfection
Place the dish in the preheated oven and bake for about 30-35 minutes, or until the eggs are set and the top is beautifully golden. You’ll know it’s ready when it slightly puffs up and a knife inserted into the center comes out clean. - Cool and Serve
Let it cool for a few minutes before slicing. This makes it easier to serve and gives the flavors a moment to settle and deepen.
HELPFUL TIPS:
- Chop spinach finely so it incorporates evenly throughout the bake.
- Use freshly grated cheese if you can — it melts better and tastes richer than pre-shredded varieties.
- Customize it by adding mushrooms, tomatoes, or even a sprinkle of fresh herbs like parsley or chives before serving.
- Don’t overbake or the texture could turn rubbery. Keep an eye on it after the 30-minute mark!
