Ingredients

• 1 tablespoon olive oil (for sautéing)
• 1 small yellow onion, diced
• 3 cloves garlic, minced
• 10 oz (about 5 cups) fresh baby spinach
• 8 large eggs
• 1½ cups cottage cheese (full-fat or 2%)
• ½ cup crumbled feta cheese, plus extra for topping
• ¼ cup grated Parmesan cheese
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ¼ teaspoon nutmeg (optional, adds warmth)
• 8 sheets phyllo dough, thawed (or use 4 sheets in a 9×13 dish, depending on thickness)
• 3 tablespoons melted butter or olive oil, for brushing phyllo

Optional Substitutions

• Cottage cheese — Ricotta works well but has less protein and a slightly grainier texture. Greek yogurt can replace half the cottage cheese for tanginess but will be less creamy.
• Phyllo dough — For a grain-free version, use 4 large eggs extra and bake without phyllo for a frittata-style dish. You can also use puff pastry sheets for a richer texture.
• Spinach — Frozen spinach works: thaw 10 oz, squeeze dry, and add directly to the egg mixture. Kale can be substituted; sauté longer until tender.
• Feta cheese — Goat cheese offers a similarly tangy flavor but is softer. Cotija also works but is much saltier.
• Eggs — For a lower-cholesterol option, use 4 whole eggs plus 4 egg whites. The bake will be slightly less rich.
• Dairy-free — Use vegan cottage cheese, tofu cottage cheese, and omit Parmesan. Use a dairy-free feta alternative.

Instructions

1. Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with nonstick spray or butter.
2. Sauté the aromatics: In a large skillet, heat olive oil over medium heat. Add the diced onion and cook for 4-5 minutes until soft. Add minced garlic and cook for 30 seconds until fragrant.
3. Wilt the spinach: Add the fresh spinach to the skillet in batches. Cook, stirring, until completely wilted, about 2-3 minutes. Remove from heat and let cool slightly.
4. Mix the egg base: In a large bowl, whisk the eggs until frothy. Add the cottage cheese, feta, Parmesan, salt, pepper, and nutmeg. Stir to combine.
5. Combine filling: Once the spinach mixture is cool enough to handle, chop it roughly on a cutting board. Stir the chopped spinach into the egg mixture.
6. Layer the phyllo: Unroll the phyllo sheets and keep them covered with a damp towel to prevent drying. Place 4 sheets in the bottom of the prepared dish, brushing each with melted butter. Let the edges hang over the sides slightly.
7. Pour the filling: Spread the egg and spinach mixture evenly over the phyllo layer.
8. Top with phyllo: Layer the remaining 4 phyllo sheets on top, brushing each with butter. Tuck the overhanging edges into the dish. Score the top layers into squares with a sharp knife to make serving easier.
9. Bake: Place the dish on a baking sheet to catch any drips. Bake for 35-45 minutes, until the phyllo is golden brown and the center is set (a knife inserted comes out clean).
10. Rest: Let the bake cool for 10 minutes before slicing. This helps the layers set and makes serving neat.
11. Serve warm: Top with extra crumbled feta and a sprinkle of fresh dill if desired. Enjoy!

Pro Tips

• Use full-fat cottage cheese for the creamiest texture. Low-fat versions can make the bake watery.
• Don't skip squeezing spinach if using frozen — excess liquid will make the casserole soggy.
• Let the phyllo thaw overnight in the fridge. Thawing at room temperature can make it sticky.
• Brush phyllo generously with melted butter for maximum flakiness and golden color.
• Score the top phyllo before baking to make slicing cleaner and prevent the top from shattering.
• Check for doneness by shaking the dish gently — the center should be just set, not jiggly.
• Let it rest after baking for at least 10 minutes. This firms up the custard and makes pieces hold together.
• Add a pinch of red pepper flakes for a subtle heat that brightens the flavors.
• Use a glass or ceramic dish for even baking and a nice crust on the phyllo.
• Double the recipe for a crowd — bake in two 9×13 dishes or one large roasting pan.

Variations and Substitutions

• Add ground meat: Brown ½ pound turkey or chicken sausage and mix into the filling for extra protein.
• Veggie boost: Sauté mushrooms, bell peppers, or zucchini along with the onion for more nutrients.
• Cheese swap: Use shredded mozzarella or provolone for a milder flavor; add more feta on top.
• Herb infusion: Mix in fresh dill, mint, or parsley for a more authentic spanakopita taste.
• Make it crustless: Omit the phyllo and pour the filling directly into a greased dish. Bake 25-30 minutes for a frittata.
• Mini muffin version: Bake in greased muffin tins for 15-18 minutes for portable servings.
• Gluten-free adaptation: Use gluten-free phyllo or skip the phyllo entirely as noted above.
• Dairy-free version: Replace cottage cheese with a tofu-cheddar blend, use dairy-free feta, and olive oil instead of butter.

Storage and Reheating

Fridge

Store leftovers in an airtight container in the refrigerator for up to 5 days. The phyllo will soften slightly but still tastes great.

Freezer

To freeze, cool the bake completely, then wrap the dish tightly in foil or plastic wrap, or transfer individual portions to freezer-safe bags. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat individual slices in the microwave for 1-2 minutes, or in a 350°F oven for about 10 minutes until warmed through. To restore crispiness to the phyllo, reheat in an air fryer at 350°F for 3-4 minutes.

FAQ

Can I make this cottage cheese spanakopita bake ahead? Yes! Assemble the casserole the night before, cover, and refrigerate. Bake directly from the fridge, adding 5-10 minutes to the baking time.

Can I use frozen spinach? Absolutely. Thaw 10 ounces of frozen spinach and squeeze out as much water as possible before mixing.

Is this breakfast bake gluten-free? Not as written because of phyllo dough. Use gluten-free phyllo or make it crustless for a gluten-free version.

How do I know when it's done? The casserole is done when the top is golden brown and the center is set — a knife inserted in the center should come out clean, and the internal temperature should reach 160°F.

Can I skip the phyllo? Yes, you can make this as a crustless frittata. Pour the filling into a greased dish and bake 25-30 minutes.

What if my cottage cheese is lumpy? That's normal! You can blend it in a food processor for 10-15 seconds for a smoother texture if preferred.

Can I use a different cheese? Feta is signature but goat cheese, ricotta, or even cream cheese mixed with Parmesan work well.

How many servings does this make? About 8-10 servings as a main dish, depending on how hungry your crew is. It's also great as a side for brunch for more people.
