This casserole has been my favorite go-to for busy weekend mornings and holiday brunches for years. I first combined these flavors on a chilly spring morning when I had leftover sun-dried tomatoes and a stubbornly full carton of cottage cheese. The bright, briny artichokes and chewy sun-dried tomatoes balance the creamy eggs and tangy feta beautifully. The texture is satisfying: soft, custardy eggs with pockets of tender artichoke and concentrated tomato bite, finished with a light golden edge where the eggs meet the baking dish. I love that this dish is forgiving and travel-friendly for potlucks. I discovered the combination while experimenting with a spinach-artichoke dip I wanted to make portable for breakfast; turning it into a savory egg bake produced a layered flavor that keeps well and tastes fresh even when reheated. Family and friends always ask for the recipe, and it has shown up on Mother’s Day, graduation mornings, and chilly camping breakfasts. What makes it special is its busy-weekend versatility: it can be assembled the night before, baked in the morning, or reheated slice by slice for a quick protein-packed start.

Ingredients

• Olive oil: Use 1 tablespoon of a good extra-virgin olive oil such as California Olive Ranch for a clean fruitiness that sautés the shallots without overpowering the dish.
• Shallot: One small shallot, minced finely for about a mild onion-sweet base; look for firm, dry skin and avoid sprouting bulbs.
• Spinach: Four packed cups of raw spinach; baby spinach works best because it wilts quickly and distributes evenly through the base.
• Garlic: Two cloves, minced for aromatic depth; press or mince finely to avoid large garlic pockets.
• Artichoke hearts: One 14-ounce can, drained and chopped — canned quartered hearts are convenient and deliver tangy bite that holds up in baking.
• Sun-dried tomatoes: One 7-ounce jar, drained and chopped; oil-packed tomatoes are flavorful—drain and pat dry if using oil-packed to control fat content.
• Eggs: Eighteen large eggs provide the custardy structure; use room-temperature eggs for a smoother bake and more even set.
• Cottage cheese: One and one-half cups of cottage cheese adds moisture and light creaminess; small-curd or low-fat are both fine depending on preference.
• Milk: One half cup of 2 percent milk softens the texture; whole milk yields a richer finish while skim reduces fat.
• Feta cheese: Half cup crumbled feta for salty, tangy finish — opt for a block-style feta for better flavor and texture than pre-crumbled varieties.
• Fresh herbs for garnish: Chopped parsley, basil, or chives for color and bright herbal finish when serving.

Instructions

Prepare the oven and pan: Preheat the oven to 350 degrees F. Grease a 9-by-13-inch baking dish thoroughly with nonstick spray or a light brush of oil so the custard releases cleanly when cool. This ensures even browning and prevents sticking at the edges. Sauté aromatics and wilt spinach: In a large skillet over medium-high heat, warm 1 tablespoon olive oil. Add the minced shallot and cook for about 2 minutes, stirring until soft but not browned. Add the spinach and garlic and sauté for 2 to 3 minutes, stirring frequently, until the spinach is just wilted. Remove from heat — look for glossy, dark green leaves with no raw crunch remaining. Combine vegetables: Stir the drained, chopped artichoke hearts and chopped sun-dried tomatoes into the spinach mixture. Season lightly with kosher salt and freshly ground black pepper; keep in mind the feta will add additional salt later. Spread this vegetable layer evenly across the bottom of the prepared baking dish and set aside. Whisk custardy egg mixture: In a large bowl, vigorously whisk 18 large eggs with 1 and 1/2 cups cottage cheese and 1/2 cup milk until relatively smooth. Season with a touch of salt and black pepper. Whisking aerates the eggs slightly, giving the final bake a lighter texture and helping the cottage cheese break down into a creamy matrix. Assemble and finish: Pour the egg mixture evenly over the vegetable layer in the baking dish. Use a spatula to gently coax the egg mixture to fill gaps so the vegetables are distributed. Sprinkle the crumbled feta evenly over the top; it will brown slightly and create pleasant pockets of saltiness during baking. Bake and rest: Place the dish in the preheated oven and bake for 30 to 40 minutes. The center should be set and no longer jiggle; edges should develop a light golden color. A toothpick inserted in the center should come out mostly clean. Remove from the oven and let the casserole rest for 5 minutes to firm up — this makes slicing cleaner and keeps the texture custardy rather than watery.

Storage Tips

Cool the casserole to room temperature before refrigerating, then cover tightly with plastic wrap or transfer slices to an airtight container. Refrigerated portions will stay fresh for up to four days. For freezing, cut into serving squares and freeze on a tray for two hours, then transfer to a freezer-safe bag to prevent sticking. Thaw overnight in the refrigerator and reheat at 325 degrees F in a covered baking dish until warmed through. Microwaving single servings works for rushed mornings: cover loosely and heat in 30 second intervals to avoid rubbery eggs.

Ingredient Substitutions

If you prefer a dairy-free version, substitute silken tofu blended with a little non-dairy milk for the cottage cheese and skip the feta, or use a plant-based feta alternative. To reduce sodium, choose low-sodium canned artichokes and rinse sun-dried tomatoes if they are packed in oil with salt. Swap baby kale for the spinach — blanch it briefly before sautéing to soften the leaves. For a richer finish, replace half the milk with half-and-half. Each substitution alters texture slightly: tofu gives a firmer set, while higher-fat dairy makes the custard silkier.

Serving Suggestions

Serve warm squares with a simple arugula salad dressed in lemon vinaigrette to cut the richness. Fresh herb garnish brightens each portion: chopped basil emphasizes the sun-dried tomatoes, parsley cleanses the palate, and chives echo the savory egg notes. For brunch, offer toasted sourdough and a small bowl of sliced olives or roasted red peppers. This dish pairs well with light sparkling wine or herbal tea for a relaxed weekend meal.

Cultural Background

This casserole is a modern American interpretation of Mediterranean flavors combined with classic baked egg dishes. Spinach and artichoke have long been combined in dips and spreads across American kitchens; folding those ingredients into an egg-based bake is a practical adaptation that blends convenience and flavor. The inclusion of sun-dried tomatoes nods to Southern European preservation techniques, where concentrated tomato flavor brings richness without heavy sauces.

Seasonal Adaptations

In spring, add blanched asparagus tips or fresh peas for brightness. Summer benefits from using fresh cherry tomatoes gently roasted first instead of sun-dried tomatoes. In autumn and winter, swap spinach for Swiss chard or kale and add a few tablespoons of roasted red peppers for sweetness. Fresh herbs can be tailored to seasonality: basil in summer, tarragon in spring, and parsley or chives year-round.

Meal Prep Tips

Assemble the dish the night before by completing all steps through pouring the egg mixture over the vegetables, then cover and refrigerate. Bring to room temperature for 20 minutes before baking and add a few extra minutes to the bake time if still cold from the fridge. Portion into individual silicone cups or small casserole dishes to make grab-and-go breakfasts that reheat evenly. Label and date frozen portions for simple weekday warming.

This casserole is approachable, flavorful, and forgiving — perfect for sharing with friends and family. Try it once and you’ll find little ways to make it your own, whether that’s a sprinkle of smoked paprika, a handful of olives, or a drizzle of good olive oil before serving. Enjoy the ritual of a shared breakfast and the easy satisfaction of a well-made, comforting dish.
