This breakfast casserole has been one of my favorite weekend rituals for years: a warm, savory tray that fills the kitchen with the smell of garlic and browned feta and brings everyone to the table without fuss. I first assembled this combination on a sleepy Sunday morning when guests were on their way and the pantry offered little more than a jar of sun-dried tomatoes and a can of artichokes. The balance of slightly chewy sun-dried tomato, tender artichoke heart, and bright spinach wrapped in a rich egg and cottage-cheese custard felt like a revelation — hearty, bright, and forgiving. What makes this bake special is how flexible it is. The cottage cheese keeps the egg custard lush without becoming heavy, while the feta adds salty pockets that caramelize a touch around the edges. The texture is creamy in the center with a slight golden top and crisped corners; the taste is Mediterranean-bright, making it feel both comforting and fresh. I often prepare it a day ahead and pop it into the oven in the morning for an easy holiday brunch that still tastes homemade and thoughtful.

Ingredients

• Olive oil (1 tablespoon): Use a mild extra-virgin olive oil for sauteing; it adds subtle fruitiness and prevents the shallot from sticking — avoid smoky or robust oils that can overpower the dish.
• Shallot (1, minced): Shallot gives a softer, slightly sweet onion flavor. If you only have onions, use 2 tablespoons finely chopped yellow onion.
• Spinach (4 cups packed): Baby spinach works best because it wilts quickly and doesn’t need chopping. Look for bright, unblemished leaves.
• Garlic (2 cloves, minced): Fresh garlic is essential for aroma; add it briefly to avoid bitterness from overcooking.
• Kosher salt and black pepper: Season to taste; I start with 1 teaspoon kosher salt and 1/2 teaspoon freshly cracked black pepper for the whole dish and adjust if needed.
• Artichoke hearts (14 oz can, drained and chopped): Quartered marinated or plain canned artichokes both work — drain well to avoid watery custard.
• Sun-dried tomatoes (7 oz jar, drained and chopped): Tomatoes packed in oil add richness; if using dry-packed, rehydrate in warm water for 10 minutes and drain.
• Eggs (18 large): The structure of the bake relies on eggs — large eggs give the right custard texture.
• Cottage cheese (1 1/2 cups): Adds creaminess and a light tang; small-curd full-fat cottage cheese yields the best texture.
• Milk (1/2 cup): Any milk works — whole milk yields a richer custard, but 2% is a fine substitute.
• Feta cheese (1/2 cup): Crumbled on top to create salty pockets; choose a block-style feta and crumble yourself for the best texture.
• Fresh herbs for garnish: Chopped parsley, basil, or chives brighten the finished dish and add color.

Instructions

Prep the oven and pan: Preheat the oven to 350°F. Grease a 9×13-inch baking dish with nonstick spray or a little olive oil rubbed over the surface. Preheating ensures even cooking and helps the edges set and brown properly while the center finishes. Sauté the aromatics and spinach: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the minced shallot and cook for about 2 minutes until softened but not browned. Stir in the garlic and cook 30 seconds until fragrant, then add the packed spinach. Toss and cook 2–3 minutes until wilted and most liquid has evaporated. Remove from heat to prevent overcooking. Add artichokes and sun-dried tomatoes: Fold the drained, chopped artichoke hearts and chopped sun-dried tomatoes into the wilted spinach. Taste and season with kosher salt and freshly cracked black pepper. If your sun-dried tomatoes were packed in oil, taste before adding salt as they may be salty already. Spread vegetables in the pan: Transfer the vegetable mixture to the prepared baking dish and spread into an even layer to help the eggs set uniformly around the pieces. Mix the egg custard: In a large bowl, whisk together 18 large eggs, 1 1/2 cups cottage cheese, and 1/2 cup milk until fairly smooth — small curds from the cottage cheese are fine. Season lightly with salt and pepper. Whisking aerates the mixture slightly and helps create a tender custard. Assemble, top and bake: Pour the egg mixture evenly over the vegetable layer. Gently stir a couple times with a spatula to nestle vegetables into the custard. Sprinkle 1/2 cup crumbled feta evenly over the top. Bake at 350°F for 30–40 minutes, until the center is set and the edges are lightly golden. A knife inserted in the middle should come out clean or with a few moist crumbs. Rest and garnish: Remove from oven and let cool 5 minutes for easier slicing. Garnish with chopped parsley, basil, or chives before cutting into squares and serving warm.

Storage Tips

Allow the pan to cool to room temperature for no more than two hours before refrigerating. Store in an airtight container or cover the baking dish tightly with foil. Refrigerated portions will keep well for 3–4 days; to freeze, cut into single servings, flash-freeze on a sheet tray, then transfer to a freezer bag for up to 3 months. Reheat frozen portions in a 350°F oven covered with foil for 20–25 minutes, removing foil at the end to crisp the top, or microwave at medium power in 30-second increments until warm.

Ingredient Substitutions

If you need dairy-free options, replace cottage cheese with a silken tofu blended until smooth and use a dairy-free milk; omit feta or swap for a plant-based salty crumble. For lower sodium, rinse canned artichokes and choose a no-salt-added sun-dried tomato option. Swap spinach for baby kale or Swiss chard — increase sauté time slightly to soften the tougher greens. To make it lighter, use egg whites for half the eggs and low-fat cottage cheese.

Serving Suggestions

Serve warm squares with a crisp green salad and a simple lemon vinaigrette to cut through the richness. For brunch, offer roasted potatoes or crusty bread and a fruit platter. Garnish with fresh chopped herbs and a light drizzle of extra-virgin olive oil for color and brightness. A dollop of plain Greek yogurt or a side of pesto pairs beautifully for more Mediterranean flavor.

Cultural Background

This bake blends Mediterranean ingredients — artichoke, feta, and sun-dried tomato — with a classic American breakfast-casserole format that emerged mid-century as a make-ahead solution for feeding families. The combination nods to Greek and Italian flavors while embracing the convenience of layered bakes popular in North American weekend brunch culture. It’s a contemporary hybrid that’s both comfort food and light enough to feel fresh.

Seasonal Adaptations

In spring and summer, swap sun-dried tomatoes for halved cherry tomatoes and add fresh basil for brightness. In fall and winter, fold in sautéed mushrooms or roasted red peppers for more depth. For holiday mornings, add a touch of smoked paprika or a handful of chopped roasted pecans on top for crunch and warmth.

Meal Prep Tips

Assemble the casserole the night before, cover, and refrigerate. In the morning, remove from the fridge while the oven preheats and bake straight from cold (adding 5–7 minutes to baking time). Portion into single-serving containers for grab-and-go breakfasts; store in the refrigerator and reheat quickly in the microwave at work or in the oven at home.

There’s something quietly celebratory about a pan of warm, herb-sprinkled custard squares set out for family and friends. This casserole is an invitation to linger over morning coffee and conversations — make it your own, and don’t be surprised if it becomes the centerpiece of your next brunch.
