Day-old crusty bread soaks up a rich egg-and-milk custard while pockets of tangy feta and wilted spinach punctuate each bite, giving a pleasing contrast between the soft, custardy interior and the lightly crisped top finished with nutty Parmesan. Sautéing the onions and cooking the spinach first concentrates flavor and removes excess moisture so the strata bakes up golden instead of soggy. It’s an ideal make-ahead centerpiece for holiday mornings or casual weekend gatherings—assemble it the night before, refrigerate, then pop it in the oven while you finish coffee. The combination of tangy feta and savory Parmesan keeps the profile bright and savory, and the straightforward ingredient list makes it easy to adapt: toss in cooked bacon or roasted peppers for a heartier version, or swap bread types to change the texture. Serve it warm with a squeeze of lemon or chopped herbs to lift the richness and you’ve got a crowd-pleasing, sliceable breakfast that travels well from kitchen to table. ## Recipe Information - Prep Time: 25 minutes - Cook Time: 45 minutes - Total Time: 70 minutes - Servings: 2 - Difficulty: Easy - Category: Breakfast ## Ingredients ### Preheat and prepare bread - 8 cups Day-old crusty bread, cut into 1-inch cubes - 2 tablespoons Extra-virgin olive oil ### Sauté onion and wilt spinach - 1 medium Yellow onion, finely chopped - 10 cups (packed) Fresh baby spinach ### Layer filling and whisk custard - 8 large Large eggs - 2 1/2 cups Whole milk - 8 ounces Feta cheese, crumbled - 1 1/2 teaspoons (combined) Kosher salt and freshly ground black pepper ### Top with Parmesan and chill (optional) - 1/2 cup (grated) Grated Parmesan cheese ## Instructions ### 1. Preheat and prepare bread Preheat the oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish with 1 tablespoon of the olive oil, then spread the cubed day-old bread evenly in the dish so it forms a single layer. ### 2. Sauté onion and wilt spinach Heat the remaining 1 tablespoon olive oil in a large skillet over medium heat and cook the chopped onion until soft and translucent, about 4–5 minutes. Add the spinach in batches and cook, stirring, until wilted and most of the liquid has evaporated; remove from heat and let cool slightly. ### 3. Layer filling and whisk custard Evenly scatter the sautéed spinach and onion over the bread cubes and crumble the feta on top. In a large bowl, whisk together the eggs, milk and the salt-and-pepper mixture until smooth, then pour the custard evenly over the bread, pressing gently so the bread soaks up the liquid. ### 4. Top with Parmesan and chill (optional) Sprinkle the grated Parmesan over the strata. For best make-ahead results, cover and refrigerate for 30 minutes up to overnight to allow the custard to fully absorb; if baking immediately, let the assembled dish sit at room temperature for 20 minutes while the oven finishes preheating. ### 5. Bake until set and golden Bake uncovered at 350°F (175°C) for 35–45 minutes, or until the center is set and the top is golden brown. If the top begins to brown too quickly, tent loosely with foil for the final 10–15 minutes. ### 6. Rest and serve Let the strata rest for 10–15 minutes after removing from the oven so it firms up for clean slicing. Cut into wedges and serve warm, garnished with extra crumbled feta or chopped fresh herbs if desired. ## Nutrition Estimated nutrition per serving (1 serving): - Calories: 1512 kcal - Protein: 82.1 g - Carbohydrates: 112.6 g - Fat: 81 g - Saturated Fat: 37 g - Fiber: 8.4 g - Sugar: 33.1 g - Cholesterol: 992.6 mg - Sodium: 4367.9 mg - Potassium: 1889.8 mg - Calcium: 1738.9 mg - Iron: 14.1 mg - Vitamin D: 9.1 mcg ## Tips ### Dry the spinach well After wilting, press the spinach in a fine-mesh strainer or squeeze in a clean kitchen towel to remove excess liquid that would otherwise waterlog the strata. ### Use day-old bread Slightly stale bread soaks the custard rather than turning into mush; if your bread is fresh, cube and dry it on a sheet pan at 300°F for 10–15 minutes first. ### Evenly distribute custard Pour the egg-milk mixture slowly and gently press the bread down with a spatula so each cube absorbs the custard for uniform texture. ### Control top browning If the Parmesan browns too quickly, tent the dish with foil during the last 10–15 minutes to prevent burning while the center finishes cooking. ### Salt cautiously Feta and Parmesan are salty; hold back a little of the added salt when whisking the custard, then taste a cooked edge and adjust if needed. ## Variations and Substitutions ### Add cooked sausage Fold in 8 ounces of crumbled, cooked breakfast sausage or diced cooked ham for added protein and a savory, smoky depth. ### Mediterranean twist Swap half the feta for chopped sun-dried tomatoes and add a tablespoon of chopped oregano for a brighter, more aromatic flavor. ### Greens mix Substitute a mix of kale and spinach—massage the kale briefly before sautéing to soften its texture and reduce cooking time. ### Make it vegetarian-friendly (vegan) Use firm tofu blended with 2–3 tablespoons chickpea flour and a splash of non-dairy milk as the custard, and swap feta for a tangy vegan cheese; bake a bit longer until set. ## Notes This strata is forgiving and scales well for a crowd—prepare it the night before for stress-free entertaining. Home cooks will love how the feta brightens the custard and the dish holds together for easy slicing. ### Storage and Make-Ahead Cool the strata completely, then refrigerate in an airtight container for up to 3–4 days. For longer storage, cut into portions, wrap tightly and freeze for up to 2 months; thaw in the fridge overnight before reheating. Reheat slices in a 325°F oven for 10–15 minutes (or until warmed through) to restore some crispness—microwaving is faster but will soften the crust. ### Serving Suggestions Serve the strata with a bright, simple salad such as arugula tossed with lemon vinaigrette or a tomato-cucumber salad to cut the richness. Roasted breakfast potatoes or a platter of fresh fruit make it feel like a full brunch, and drinks like fresh-squeezed orange juice, a crisp Prosecco or good coffee round out the meal. ## Frequently Asked Questions ### Can I use fresh bread instead of day-old? You can, but fresh bread will absorb differently and can become soggy; briefly dry the cubes in a low oven (about 300°F for 10–15 minutes) to remove moisture before assembling. ### How long can the assembled strata sit before baking? It can sit in the refrigerator for 30 minutes up to overnight (around 8–12 hours) to allow the custard to fully soak in; avoid leaving it more than 24 hours for best texture. ### How do I know when the strata is fully cooked? The center should be set with only a slight jiggle when you gently shake the dish; an instant-read thermometer inserted into the center should read about 165°F. ### My strata was watery—what went wrong? Most likely excess moisture from the spinach or fresh bread; make sure to thoroughly squeeze wilted spinach and use day-old or dried bread so the custard is absorbed rather than pooling. ### Can I make this lower in fat? You can swap to 2% milk or part-skim milk and use a lower-fat feta, but the custard will be less rich and slightly firmer—season carefully since lower-fat options may mute flavor. ## Related Recipes and Guides - [Pumpkin Oat Muffins](https://www.topshelf.recipes/recipes/pumpkin-oat-muffins) - [Chocolate Chip Banana Muffins](https://www.topshelf.recipes/recipes/brown-butter-chocolate-chip-banana-muffins) - [Pad Krapow Pork](https://www.topshelf.recipes/recipes/pad-krapow-pork) - [Canning Peaches Light Syrup](https://www.topshelf.recipes/recipes/canning-peaches-light-syrup) - [Easy Homemade Yogurt Without Special Equipment](https://www.topshelf.recipes/recipes/easy-homemade-yogurt-without-special-equipment) - [Maple Bacon Butter Board with Cracked Pepper and Toastables](https://www.topshelf.recipes/recipes/maple-bacon-butter-board-cracked-pepper-toastables) - [Gluten-Free Weeknight Grilling Plan](https://www.topshelf.recipes/articles/gluten-free-weeknight-grilling-plan) - [Low-Fat Grill Swaps for Big Flavor](https://www.topshelf.recipes/articles/low-fat-grill-swaps-big-flavor) - [DIY Edible Monster Eyes Candy](https://www.topshelf.recipes/articles/diy-edible-monster-eyes-candy)
