This Spinach Artichoke Sun-Dried Tomato Breakfast Casserole has been a weekend obsession in my kitchen for years. I first put this combination together on a rainy Saturday when I wanted something warm and savory for brunch that could feed a crowd and travel well if we had guests. The tang of artichoke hearts and sun-dried tomatoes cuts through the rich, custardy egg base, while the spinach adds freshness and color. The texture is a satisfying balance: tender vegetables, soft curds from the cottage cheese, and a light golden top of baked egg and feta.

I remember serving this at a family brunch where three generations gathered—my grandmother reached for seconds and my teenage cousin declared it "better than takeout." It travels well to potlucks, slices cleanly for easy plating, and even reheats wonderfully. It’s a dish that feels special without being fussy: approachable techniques, pantry-friendly ingredients, and reliable results every time. If you like the flavors of a spinach-artichoke dip but want a hands-off, breakfast-friendly version, this will quickly become a staple.

Ingredients

• Olive oil (1 tablespoon): Use extra-virgin for the best aroma when sautéing shallots—it provides a clean, fruity base. I favor California or Spanish brands for consistent flavor.
• Shallot (1, minced): Shallot adds a sweet, mild onion flavor; mince finely so it softens quickly without leaving raw pockets.
• Spinach (4 cups packed): Fresh baby spinach works best—look for bright leaves without yellowing. It wilts quickly and keeps the casserole light.
• Garlic (2 cloves, minced): Fresh garlic brightens the filling; mince or grate for even distribution.
• Kosher salt & black pepper: Season in stages—season the vegetables while sautéing and taste the egg mixture before baking to adjust.
• Artichoke hearts (14 oz can, drained and chopped): Quartered or marinated artichokes both work—if choosing marinated, reduce added oil elsewhere to avoid greasiness.
• Sun-dried tomatoes (7 oz jar, drained and chopped): Oil-packed sun-dried tomatoes deliver the best texture and flavor; drain and chop so they distribute through each bite.
• Eggs (18 large): Provide the custardy structure—use large eggs at room temperature for the most even bake.
• Cottage cheese (1 1/2 cups): Adds creaminess and light curd texture; full-fat or low-fat both work, but full-fat yields a richer custard.
• Milk (1/2 cup): Whole milk creates a silkier texture; you can use 2% for a slightly lighter result.
• Feta cheese (1/2 cup): Crumbled on top for salty tang and a pretty golden finish; choose a good-quality block-style feta rather than pre-crumbled if possible.
• Garnish: Chopped parsley, basil, or chives add freshness and color—add just before serving for the best presentation.

Instructions

Preheat and prepare: Preheat the oven to 350°F. Grease a 9x13-inch baking dish with nonstick spray or a light brush of olive oil to ensure easy serving. Position an oven rack in the center so the casserole cooks evenly and develops a gentle golden edge. Sauté aromatics and wilt spinach: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the minced shallot and sauté for about 2 minutes until translucent and fragrant but not browned. Stir in the minced garlic, then add the packed spinach. Cook, tossing frequently, for 2–3 minutes until the spinach collapses and any excess moisture has mostly evaporated—this prevents a watery bake later. Combine vegetables: Remove the skillet from heat and stir in the drained, chopped artichoke hearts and chopped sun-dried tomatoes. Season the mixture lightly with kosher salt and freshly ground black pepper. Taste and adjust—since sun-dried tomatoes and feta can be salty, start with a conservative amount of salt. Layer the base: Spread the vegetable mixture evenly across the bottom of the prepared 9x13-inch dish. Pat it down slightly so the egg mixture will sit evenly on top and you won’t end up with pockets of vegetables concentrated in one area. Whisk eggs and dairy: In a large mixing bowl, whisk together the 18 large eggs, 1 1/2 cups cottage cheese, and 1/2 cup milk until blended. Season the mixture with salt and pepper to taste; whisk until combined into a smooth custard. For a silkier texture, pulse the egg mixture briefly in a blender—this is optional but yields a very even custard. Assemble and top with feta: Pour the egg-cottage cheese mixture over the layered vegetables in the pan. Use a spatula to gently stir once or twice to distribute ingredients evenly but avoid over-mixing which can deflate the egg mixture. Sprinkle the 1/2 cup crumbled feta evenly across the top for a tangy finish. Bake and rest: Bake in the preheated oven for 30–40 minutes, or until the eggs are set in the center and the edges are lightly golden. Insert a knife or toothpick into the center—if it comes out clean and the surface has a gentle spring, it’s done. Remove from oven and let rest for 5 minutes; this short rest makes slicing neater and allows the internal temperature to stabilize.

Storage Tips

Cool the casserole to room temperature before storing to avoid condensation. For the refrigerator, cover the pan tightly with foil or transfer slices to airtight containers—use within 4 days. To freeze, wrap individual slices first in plastic wrap, then place them in a freezer-safe zip bag or container for up to 3 months. Reheat refrigerated slices in a 325°F oven for 10–15 minutes or in the microwave on medium power for 60–90 seconds; frozen slices thaw overnight in the fridge before reheating for best texture. Avoid reheating multiple times to preserve flavor and prevent dryness.

Ingredient Substitutions

Swap cottage cheese for ricotta at a 1:1 ratio for a slightly creamier texture and milder flavor. If you prefer a dairy-free version, replace cottage cheese with a firm tofu blend and use a dairy-free feta alternative; textures will differ but flavors can be adjusted with a pinch more salt and lemon zest. For a lower-sodium option, rinse canned artichokes and choose no-salt-added tomatoes, then increase fresh herbs and lemon to boost brightness. You can also add cooked sausage or bacon for extra richness—cook and drain before adding to the vegetables.

Serving Suggestions

Serve wedges warm with a crisp green salad or a fruit platter to balance the savory richness. Garnish with chopped parsley, torn basil, or snipped chives right before serving to add color and fresh notes. For a brunch spread, pair with roasted fingerling potatoes and a light vinaigrette-dressed arugula. If serving as part of a buffet, slice into 2x2-inch squares and place on a platter with toothpicks for easy grabbing.

Cultural Background

The flavor profile nods to Mediterranean influences—artichokes, olive oil, and sun-dried tomatoes recall coastal Italian and Greek combinations. While not a traditional recipe from any single region, it borrows elements of savory bakes and frittatas common across Southern Europe, adapted here into a casserole format that’s popular in American brunch culture. Combining these Mediterranean components with a custard base is a modern home-cook twist that emphasizes vibrant flavors and ease of preparation.

Seasonal Adaptations

In spring, add fresh peas and ramps for a bright take; in summer, swap sun-dried tomatoes for blistered cherry tomatoes and add fresh basil. Autumn invites roasted red peppers and a sprinkle of smoked paprika for warmth, while winter is perfect for adding chopped kale and a handful of roasted mushrooms. Adjust oven times slightly if you add moisture-rich vegetables—pre-roast or sauté them to remove excess liquid before assembling.

Meal Prep Tips

To make this ahead, complete assembly the night before and keep covered in the refrigerator; pull it out 30 minutes before baking so it comes closer to room temperature and bakes more evenly. For single-serve prep, bake once and portion into meal-prep containers for the week—these slices are great for quick breakfast reheats or packed lunches. Label containers with the bake date and use within 4 days for optimal freshness.

This casserole combines convenience and bright Mediterranean flavors in one easy dish—perfect for sharing, prepping, or enjoying as a comforting breakfast at home. Give it a try and make the herb garnish your signature touch; it’s the little things that turn a good dish into a favorite.
