Ingredients

• 8 large eggs, beaten
• 1 cup whole milk (or any dairy-free alternative)
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 tablespoon olive oil
• 1 medium onion, diced
• 1 red bell pepper, chopped
• 1 zucchini, sliced into half-moons
• 2 cups baby spinach, roughly chopped
• 1½ cups crumbled feta cheese
• 2 cups shredded cheddar (optional for extra gooey goodness)
• 1 teaspoon dried oregano or Italian seasoning

Instructions

1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with a light coating of olive oil or nonstick spray. This step ensures your **breakfast casserole** slides out cleanly—no post-bake wrestling match required.
2. Sauté the aromatics: In a large skillet over medium heat, warm the olive oil. Toss in the diced onion and red bell pepper. Cook for 4–5 minutes until they soften and start to caramelize. Don’t rush this or you’ll miss that sweet veggie depth.
3. Add zucchini and spinach: Stir in zucchini slices and chopped spinach. Cook 2–3 minutes until the spinach wilts. You want tender veggies, not soggy mush—keep an eye on texture.
4. Mix eggs and seasoning: In a roomy bowl, whisk together the eggs, milk, salt, pepper, and dried oregano. This blend forms the custardy base that holds everything together.
5. Layer the casserole: Scatter half the sautéed veggies across the bottom of the dish. Sprinkle with half the feta and cheddar. Pour half the egg mixture over, then repeat with the remaining veggies, cheeses, and eggs. Layers = flavor explosion.
6. Optional make-ahead step: Cover the dish tightly with foil and refrigerate overnight. This is your **Breakfast Casserole Overnight** secret. It frees up your morning and lets flavors marry beautifully.
7. Bake uncovered: Slide the dish into the preheated oven. Bake 30–35 minutes or until the center jiggles slightly—think more “custard” than “liquid.” If you love a golden top, broil on high for 2 minutes at the end, keeping a hawk’s eye on it.
8. Rest before slicing: Let it cool 5–10 minutes so slices hold their shape. I know you’re excited, but trust me—patience here means perfect squares, not a scrambled mess.
9. Serve warm: Cut into squares and arrange on a platter. Watch guests go back for seconds—consider this your **Brunch Potluck** bragging moment.
10. Store leftovers: Cover and refrigerate up to 4 days, or freeze individual portions for an **Easy Breakfast Casserole Make Ahead** grab-n-go treat.

Variations

Spice things up with these creative twists:
1. Sausage & Cheddar Swap: Swap half the veggies for crumbled breakfast sausage or chorizo, and switch feta for sharp cheddar. It’s basically a **Savory Breakfast** party in a pan.
2. Mediterranean Flair: Add chopped sun-dried tomatoes, olives, and a sprinkle of fresh basil. Skip the cheddar and lean fully into the feta for a Greek-style casserole.
3. Tater Tot Layer: Line the bottom with a layer of frozen tater tots—think **Easy Tater Tot Casserole** meets egg bake. You get crunchy edges and soft interior all at once. Seriously, why didn’t anyone think of this sooner?

Serving & Tips

Serve this casserole with a fresh green salad or a side of roasted potatoes for balanced **Breakfast Ideas Casserole** vibes. Drizzle with hot sauce or a dollop of salsa for a zesty kick.
Storage: Wrap leftovers tightly or transfer to an airtight container. It keeps in the fridge for up to 4 days—perfect for weekday breakfasts.
Make Ahead: Assemble the night before to save precious AM minutes. This recipe doubles as an **Overnight Breakfast Casserole With Hashbrowns** if you swap veggies for shredded potatoes.

FAQs

Can I prepare this as a Breakfast Casserole Make Ahead?

Absolutely! Simply assemble the casserole up to 24 hours in advance, cover it tightly, and store it in the fridge. When you’re ready, pop it into the preheated oven straight from the fridge, adding an extra 5–10 minutes to the bake time if it’s super chilled. This **make-ahead** trick saves morning chaos for later.

What vegetables work best in a Healthy Breakfast Casserole?

I love using bell peppers, spinach, zucchini, and onions for that colorful crunch. You can also sneak in shredded carrots or broccoli florets for extra nutrients. Just chop them uniformly so they cook evenly. Feel free to riff based on what’s in your crisper drawer—flexibility FTW!

Can I freeze leftover slices?

Yes! Wrap individual portions tightly in plastic wrap and foil, then stash in the freezer for up to 2 months. To reheat, thaw overnight in the fridge and warm in a 350°F oven for 10–12 minutes, or zap in the microwave for a quick grab-n-go meal. It’s basically a **breakfast casserole** on autopilot.

How do I turn this into an Overnight Breakfast Casserole With Hashbrowns?

Just swap the sautéed vegetables for a layer of frozen hashbrowns. Assemble everything, cover, and refrigerate overnight. In the morning, bake as usual. You’ll get crispy edges from the tots and a creamy egg center—trust me, it’s a crowd-pleaser at any **brunch potluck**.
