This casserole became a weekend ritual in my kitchen the first winter I wanted something bright and savory to break the monotony of oatmeal and toast. I discovered the flavor combination while cleaning out my pantry: a jar of sun-dried tomatoes, a can of artichoke hearts, and a bag of spinach tucked into the back of the fridge. The result? A warm, custardy bake that tastes like a fresh spinach-artichoke dip transformed into breakfast. It wakes up the table with bright tomato sweetness, briny artichoke bites, and the delicate tang of feta against a soft egg base. I remember serving this to a houseful of friends after a holiday run; everyone reached for seconds before coffee was poured. The texture is what keeps people coming back — silky eggs that hold together but still feel light, pockets of soft artichoke, and the chewy pop of sun-dried tomatoes. It’s forgiving to improvise with what you have, yet specific enough that when you follow the proportions, it reliably turns out creamy and golden every time.

Ingredients

• Olive oil: Use a good-quality extra-virgin olive oil for flavor; 1 tablespoon adds a subtle fruity note and helps soften aromatics without overpowering the other ingredients.
• Shallot: One small shallot, minced, provides a sweet, mild onion flavor—perfect for gently building savory depth without biting sharpness.
• Spinach: Four cups packed fresh leaves wilt quickly and add color and nutrients; baby spinach works great because it wilts faster and blends seamlessly into the custard.
• Garlic: Two cloves, minced, bring an aromatic backbone—don’t overcook it or it will turn bitter; add near the end of wilting the greens for best flavor.
• Artichoke hearts: A 14-ounce can, drained and chopped. Look for artichokes packed in water rather than oil for a cleaner flavor that won’t make the bake oily.
• Sun-dried tomatoes: A 7-ounce jar, drained and chopped. Choose tomatoes packed in oil for softness and richness; if packed dry, rehydrate briefly in hot water before chopping.
• Eggs: Eighteen large eggs provide the custardy structure—use room-temperature eggs so they blend evenly with the dairy.
• Cottage cheese: One and a half cups of small-curd cottage cheese adds creaminess and keeps the texture light; full-fat cottage cheese yields the richest result.
• Milk: Half a cup of milk (whole milk recommended) for a tender, slightly custardy set; you can substitute a milk alternative but flavor and texture will change.
• Feta cheese: Half a cup crumbled on top adds salty tang—look for a block of feta and crumble by hand for the best texture.
• Herbs for garnish: Chopped parsley, basil, or chives brighten every bite and make the pan look finished when served.

Instructions

Preheat and prepare the pan: Set the oven to 350°F and grease a 9×13-inch baking dish thoroughly with nonstick spray or a light coat of oil. A well-greased pan prevents sticking and helps the edges brown evenly; set it aside while you cook the vegetables. Sauté the aromatics and greens: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the minced shallot and cook about 2 minutes until translucent and fragrant. Add the spinach and the minced garlic, and continue to cook for roughly 3 minutes, stirring often, until the spinach has fully wilted. Taste and season with kosher salt and freshly ground black pepper. Add artichokes and sun-dried tomatoes: Remove the skillet from heat. Stir in the chopped artichoke hearts and sun-dried tomatoes, tasting as you go and adjusting salt and pepper. Spread this vegetable mixture in an even layer across the bottom of the prepared baking dish; this creates pockets of flavor within the egg custard. Whisk the eggs and dairy: In a large bowl, whisk together 18 large eggs, 1 1/2 cups cottage cheese and 1/2 cup milk until fully combined. Season lightly with salt and black pepper. Let the mixture rest for a minute so the cottage cheese can hydrate and integrate with the eggs. Assemble and top with feta: Pour the egg mixture evenly over the layered vegetables in the baking dish. Use a spatula to gently stir so the vegetables are distributed evenly throughout the eggs, then sprinkle the top with 1/2 cup crumbled feta. The feta will brown slightly and add a salty finish. Bake and cool: Bake in the preheated 350°F oven for 30 to 40 minutes, until the eggs are set in the center and the edges are slightly golden. To check doneness, insert a knife into the center — it should come out mostly clean. Remove from oven and cool for 5 minutes before cutting into squares. Garnish with chopped parsley, basil or chives and serve warm.

Storage Tips

Store leftover squares in an airtight container in the refrigerator for up to four days. For best reheating, preheat the oven to 350°F and warm individual portions for 8–12 minutes, or microwave a single piece for 60–90 seconds, though oven reheating preserves texture better. To freeze, wrap cooled slices tightly in plastic wrap and place in a freezer bag; they’ll keep up to three months. Thaw overnight in the fridge before reheating and refresh with a quick 5-minute broil if you want the top to regain a little color.

Ingredient Substitutions

If you don’t have cottage cheese, substitute an equal volume of ricotta for a slightly sweeter, silkier custard. For a lower-sodium option, use low-sodium feta or omit the feta and top with a sprinkle of freshly grated Parmesan before serving. If sun-dried tomatoes are packed dry, rehydrate them in warm water for 10 minutes, then drain and chop; or swap in roasted red peppers for a milder, sweeter profile. To make this dairy-free and vegan, replace eggs with a chickpea flour batter and use dairy-free cottage and feta alternatives — results will shift toward a denser texture.

Serving Suggestions

Serve warm squares alongside a crisp arugula salad dressed in lemon vinaigrette to cut the richness, or present it with toasted sourdough and seasonal fruit for a brunch spread. For a heartier meal, slice and tuck into soft rolls for breakfast sandwiches with an extra smear of hummus or pesto. Garnish with fresh basil, parsley, or chives for color and brightness right before serving. A light, sparkling beverage or a citrusy iced tea complements the tang of the feta and sun-dried tomatoes exceptionally well.

Cultural Background

This dish blends Mediterranean flavors—artichokes, feta and sun-dried tomatoes—with a classic American breakfast format. Artichokes and sun-dried tomatoes are staples in Mediterranean cuisines, prized for their preserved, concentrated flavors. Turning these ingredients into an egg casserole is an American adaptation that borrows the bright, briny components of mezzes and transforms them into a comforting, communal morning bake. It’s a modern cross-cultural approach that honors both freshness and convenience.

Seasonal Adaptations

In spring and summer, swap sun-dried tomatoes for fresh, halved cherry tomatoes roasted briefly for sweetness and texture. In autumn, fold in a cup of sautéed mushrooms or caramelized onions for earthiness. For holiday mornings, add a handful of chopped roasted red pepper and a sprinkle of smoked paprika for warmth. You can also finish with seasonal herbs: basil in summer, chives in spring and flat-leaf parsley in winter.

Meal Prep Tips

Assemble the vegetable layer and whisk the eggs the night before; store the components separately and pour the egg mixture over the vegetables just before baking for the freshest texture. If you prefer true make-ahead convenience, bake the casserole fully, cool completely, then refrigerate. Reheat later and garnish just before serving. Use portion-sized containers for grab-and-go breakfasts — they reheat quickly and make weekday mornings effortless.

This casserole is one of those recipes that grows more beloved the more you make it: a dependable, flavorful dish that adapts to seasonal produce, pantry finds, and guest preferences. Share it with friends or keep it as your own weekend treat — either way, it’s a satisfying way to start the day.
