Evening Meals

Tender spinach, tangy feta, and a creamy egg-and-cottage-cheese filling make this savory pie a practical choice for breakfast, lunch, or a simple dinner. It bakes in one dish until gently golden, with a soft, sliceable center and plenty of greens in every wedge.

This version is crustless, so there is no pastry to roll or layer. Cottage cheese blends into the eggs to create the base, while feta brings the distinctive salty flavor. A little onion, garlic, and dill round out the filling without overwhelming the spinach.

Serve a warm slice with tomatoes and cucumber, or pair it with toast or roasted potatoes for a larger meal. The pie also reheats well, making it useful when you want a savory dish ready for the next day.

This is a suggested recipe developed from the dish title and has not been kitchen-tested. Use the filling’s doneness rather than the baking time alone, since dish depth and ingredient moisture affect the result.

Why You’ll Love This Pie

No pastry preparation: The egg filling sets into a crustless pie.

Protein-rich ingredients: Eggs, cottage cheese, and feta provide the protein without powder.
Plenty of spinach: A well-drained package of spinach distributes through the entire dish.
Flexible serving: Enjoy it for breakfast, lunch, or dinner.
Easy portions: Cut into six wedges for consistent servings.
Useful leftovers: Refrigerated slices can become a quick meal with a fresh side.

What Kind of Spinach Pie Is This?

This is a crustless egg-based spinach pie with cottage cheese and feta. It shares the spinach, feta, and herb combination found in many savory pies, but it is not a traditional phyllo-wrapped spanakopita. Expect a tender baked egg filling rather than crisp pastry layers.

Blending the cottage cheese with the eggs reduces visible curds and gives the base a more uniform consistency. The feta stays in small crumbles, creating pockets of stronger flavor.

The pie should hold a slice after resting while remaining moist. It should not have a wet center or release a large pool of liquid when cut. Removing water from the spinach is the most important preparation step for achieving that balance.

Ingredients

1 tablespoon olive oil, divided
½ medium yellow onion, finely diced
2 garlic cloves, minced
1 package frozen chopped spinach, 10 oz, thawed completely
6 large eggs
1 cup plain cottage cheese, preferably 2% or full-fat
¾ cup crumbled feta cheese, about 4 oz
2 tablespoons chopped fresh dill, or 1 teaspoon dried dill
¼ teaspoon black pepper
⅛ teaspoon ground nutmeg, optional
Up to ¼ teaspoon fine salt, optional and to taste

Ingredient Notes

Spinach: Frozen chopped spinach makes the quantity easy to repeat. Thaw it fully, then squeeze out as much water as possible. The package weight is measured before thawing and squeezing. Do not replace it with an equal cup measure of loose raw leaves; raw spinach contains much more volume before cooking.

Eggs: Six large eggs provide the main structure. The pie is intended to be fully baked, not soft or runny like lightly cooked scrambled eggs.

Cottage cheese: Use a plain product with a texture you enjoy. If liquid is pooled on the surface, drain that off before measuring. Blending makes the filling smoother, but it does not remove excess moisture. Very watery cottage cheese can produce a softer pie.

Feta: Feta brings both tang and salt. Block feta that you crumble yourself often has a pleasant texture, while precrumbled feta is convenient. Drain brined feta and pat away excess surface moisture. Taste the cheese before deciding whether to add any salt to the egg mixture.

Onion and garlic: Sautéing the onion first softens it and removes some moisture. Raw onion can stay firm inside an egg bake, so keep this preparation step. Add garlic near the end to avoid scorching it.

Dill: Dill gives the spinach and feta a fresh herbal finish. Parsley can be substituted for a milder flavor. Use less dried herb than fresh because the flavor is more concentrated.

Nutmeg: An optional small pinch complements spinach. Measure lightly so it remains a background note.

How to Make High-Protein Spinach & Feta Pie

1. Thaw and Squeeze the Spinach

Place the thawed spinach in a clean kitchen towel or several layers of sturdy cheesecloth. Gather it into a bundle and squeeze over the sink until very little liquid comes out.

Open the bundle and separate the compressed spinach with a fork or your fingers. Breaking it apart makes it easier to distribute through the filling without dense clumps.

If thawing in advance, keep the spinach refrigerated. Do not rely on baking to evaporate all the water from an unsqueezed package.

2. Prepare the Dish and Oven

Heat the oven to 375°F. Grease a deep 9-inch pie dish using about one teaspoon of the measured olive oil. Reserve the remaining two teaspoons for the skillet.

Use a dish with at least 6 cups capacity and leave room below the rim for the filling to puff slightly. If your dish is shallow, bake excess filling separately in a greased ramekin rather than overfilling. A small ramekin will need less cooking time.

3. Cook the Aromatics

Heat the remaining oil in a skillet over medium heat. Add the onion and cook for about 4–6 minutes, stirring, until softened. Add the garlic and cook for another 30 seconds.

Stir in the squeezed spinach and cook for 1–2 minutes, separating any remaining clumps. The mixture should look relatively dry, with no puddle in the skillet. Remove from the heat and let cool until only slightly warm.

4. Blend the Egg Base

Place the eggs and cottage cheese in a blender or food processor. Blend briefly until mostly smooth. Add black pepper, optional nutmeg, and optional salt. Start with little or no salt if the feta is strongly seasoned.

Do not taste the raw egg mixture. You can judge the need for salt from the cheese and correct individual baked servings at the table.

5. Combine the Filling

Pour the egg mixture into a large bowl. Fold in the cooled spinach mixture, dill, and feta. Stir gently but thoroughly so the spinach is evenly dispersed.

Keep the feta in small crumbles rather than blending it with the eggs. This gives the pie little pockets of tangy cheese.

6. Fill and Bake

Pour into the prepared dish and spread the spinach evenly. Bake on the center rack for about 35–45 minutes, beginning to check near 35 minutes.

The edges should be set and the center should no longer look liquid. A food thermometer inserted into the middle should reach 160°F. A slight soft movement is different from a wet, sloshing center; use temperature to help confirm doneness.

If the top browns before the center is ready, cover loosely with foil and continue baking. A deeper or cooler dish may need longer than the suggested range.

7. Rest Before Slicing

Let stand for 10–15 minutes before cutting. The pie will settle slightly as it cools, and resting makes it easier to lift clean wedges.

Cut into six slices and serve warm. A spatula with a thin edge helps release the first piece without breaking it.

Tips for a Firm but Tender Slice

Remove spinach water thoroughly. This matters more than extra mixing or adding more cheese. Wet greens are a common reason for a watery pie.

Cool the skillet mixture briefly. Very hot spinach can begin cooking the eggs unevenly as you combine them.

Avoid overfilling. Leave a little room at the top, and use the dish capacity rather than diameter alone as a guide.

Do not overbake to make it firmer. Excess cooking can make eggs rubbery and encourage liquid to separate. Check the center and remove the pie when properly set.

Allow the resting time. Cutting straight from the oven can make a tender filling appear looser than it will be after a short rest.

Season with the feta in mind. Salty cheese can provide enough seasoning without the full optional amount of salt.

Troubleshooting

Problem	Likely cause	Helpful adjustment
Liquid collects around slices	Spinach or cottage cheese was very wet	Squeeze spinach thoroughly and drain pooled liquid from the cheese next time.
Center remains wet	Dish is deep or baking time insufficient	Continue baking, tenting if needed, until the center reaches 160°F.
Filling is rubbery	Eggs were overbaked	Check earlier and remove once properly set.
Pie falls apart when sliced	It was cut too hot or not fully set	Rest before slicing and verify doneness during baking.
Spinach forms dense clumps	Squeezed spinach was not separated	Break it apart before combining with the egg base.
Flavor is too salty	Feta plus added salt	Omit optional salt next time and serve with unsalted fresh vegetables.
Top browns quickly	Oven heat or dish placement	Move away from direct top heat if necessary and tent loosely with foil.

Variations

Fresh Spinach Version

Cook fresh spinach separately until fully wilted, cool it, squeeze dry, and chop. Use enough cooked, squeezed spinach to approximate the amount produced by the 10 oz frozen package. Fresh spinach yield varies, so do not assume a small handful replaces the package.

Spinach and Mushroom

Sauté a small quantity of finely chopped mushrooms until their released liquid has evaporated, then cool and fold into the filling. Extra vegetables increase volume, so watch dish capacity and bake excess separately if needed.

Pepper and Herb

Add a small amount of well-drained, finely chopped roasted red pepper and use parsley alongside the dill. Pat the peppers dry first to avoid introducing extra water.

A Little Heat

Add a pinch of red pepper flakes to the spinach while it cooks. Keep it modest so the dill and feta remain noticeable.

Individual Egg Bakes

Divide the filling among greased muffin cups or ramekins, leaving expansion room. Begin checking much earlier than for a full pie and cook each center to 160°F. The exact time depends on portion depth and container size.

Serving Suggestions

For breakfast, serve a warm wedge with tomatoes and a slice of toast. For lunch, pair it with cucumber, olives, and a simple green salad. Lemon-dressed vegetables provide a fresh contrast to the creamy filling.

For dinner, add roasted potatoes or a bean salad according to your appetite. The pie itself contains no crust, but that does not require every accompaniment to be bread-free.

A little plain yogurt with chopped herbs can be served alongside. Keep strong salty toppings restrained because feta already supplies plenty of flavor.

Make-Ahead and Storage

You can thaw and squeeze the spinach and cook the onion mixture a day ahead. Refrigerate those prepared components promptly in a covered container, then mix with the eggs and cheeses when ready to bake.

For convenient portions, bake the whole pie, rest it, and refrigerate leftovers in shallow covered containers within 2 hours. Keep refrigerated and use within 3–4 days.

Freeze cooled individual slices for up to 2 months for best quality, wrapping well before placing in a freezer-safe container. The filling may release a little moisture or change texture after thawing. Thaw overnight in the refrigerator.

How to Reheat

Place a slice in an oven-safe dish and cover loosely. Warm in a 325°F oven until the center reaches 165°F. Timing depends on slice thickness and starting temperature, so check the middle rather than relying on a fixed number of minutes.

For quicker reheating, microwave an individual portion in short intervals, checking and turning as needed. Avoid prolonged heating after it is hot, which can toughen the eggs. Reheat only the amount you intend to eat.

Frequently Asked Questions

Does this have a pastry crust?

No. This recipe is a crustless egg pie. Adding pastry changes the preparation, baking needs, and nutrition and is not part of these directions.

Will the cottage cheese taste strong?

Blending distributes it through the eggs, while feta, garlic, and herbs provide the more noticeable flavors. Choose plain cottage cheese without added flavorings.

Can I skip blending?

Yes. Whisk the eggs and stir in the cottage cheese, expecting some curds to remain visible. The texture will be less uniform but the basic preparation is similar.

Can I use only egg whites?

That would change structure, flavor, volume, and moisture. This formula is written for six whole large eggs; an egg-white version needs its own adjustments.

Can I use ricotta instead of cottage cheese?

Ricotta changes both texture and protein content, and some products are much wetter than others. It is not a guaranteed identical replacement. If experimenting, drain excess liquid and monitor the center during baking.

Is this low-carb?

It does not contain a flour or pastry crust, but its carbohydrate content still depends on the vegetables and dairy products used. Calculate from your ingredient labels before assigning a precise carbohydrate or net-carb figure.

How much protein is in one slice?

As an illustration, six eggs may supply about 36 grams, a cup of cottage cheese about 24–28 grams, feta about 16 grams, and spinach several more grams. Divided into six slices, the pie may provide roughly 13–15 grams per slice, depending on the products. Two slices provide a larger meal portion with about twice that amount. These are estimates, not laboratory-tested values.

Why did the pie puff and then settle?

Egg mixtures can rise during baking and settle as they cool. Some settling is normal. A deeply sunken, wet center is different and suggests checking dish depth and doneness.
