Spinach Artichoke Sun-Dried Tomato Breakfast Casserole

30

Some recipes happen completely by accident, and honestly, those are often the best ones.

A few years ago, I was hosting a weekend brunch and realized I had a strange collection of ingredients sitting in the refrigerator. A half jar of sun-dried tomatoes. Some spinach. A can of artichoke hearts. Plenty of eggs.

Not exactly a plan.

Still, I started tossing things together, hoping for something decent enough to serve guests the next morning.

As the casserole baked, the kitchen filled with the smell of roasted tomatoes, melted cheese, and savory herbs. It smelled like a cozy café tucked into a quiet corner of town.

I remember peeking through the oven door every few minutes, probably more than necessary.

When I finally pulled it out, golden and bubbling around the edges, I knew we had something special.

The first bite delivered creamy eggs, tender spinach, tangy artichokes, and little bursts of sweet sun-dried tomato. Everyone went back for seconds.

Since then, this spinach artichoke sun-dried tomato breakfast casserole has become my go-to dish for holidays, brunches, meal prep, and those mornings when I want something a little extra without a lot of extra work.

How to Master the Perfect Spinach Artichoke Sun-Dried Tomato Breakfast Casserole (My Secret Method)

Start by lightly greasing a baking dish and preheating your oven to 375°F.

In a large bowl, whisk the eggs and milk until smooth and slightly frothy. Add the garlic powder, salt, and pepper.

Now stir in the spinach, chopped artichokes, sun-dried tomatoes, mozzarella, Parmesan, and onion. The mixture may look loaded with vegetables—and that’s exactly what you want.

Pour everything into the baking dish and spread it evenly.

Slide it into the oven and bake for about 35 to 40 minutes. You’ll know it’s ready when the center feels set and the top turns beautifully golden.

Allow it to rest for a few minutes before slicing. Trust me, the flavors settle and improve during that short wait.

Chef’s Notes and Tips For A Flawless Spinach Artichoke Sun-Dried Tomato Breakfast Casserole

If your spinach contains excess moisture, give it a quick squeeze with paper towels before mixing it into the casserole. Too much liquid can affect the final texture and make the casserole softer than intended.

For maximum flavor, use oil-packed sun-dried tomatoes rather than dry-packed versions. They provide richer flavor and blend beautifully into the egg mixture. A little extra Parmesan on top before baking creates a wonderfully golden crust.

Get Creative! Easy Substitutions and Fun Variations

Swap mozzarella for Gruyère, Swiss, or sharp cheddar. Add cooked turkey sausage, bacon, or diced ham for extra protein.

You can also include mushrooms, roasted red peppers, kale, or zucchini. This cheesy spinach breakfast bake recipe adapts easily to whatever vegetables happen to be in your refrigerator.

Lighten It Up! Simple Swaps for a Healthier Spinach Artichoke Sun-Dried Tomato Breakfast Casserole

Use reduced-fat cheese and replace some whole eggs with egg whites to lower calories and fat.
