How Many Calories Are In Spinach Quiche? | Smart Slice Math

Spinach quiche is a custardy egg pie packed with greens and cheese. The calorie math looks simple at first glance, but it moves fast once you change the crust, the dairy, or the slice size. A light crustless pan can land near the calorie count of plain scrambled eggs, while a deep bakery wedge can rival a slice of cheesy breakfast pizza.

This guide breaks down calorie ranges per slice, where those calories come from, how serving size changes the total, and easy tweaks that shave fat grams without losing the brunch feel.

Calorie Count In A Slice Of Spinach Quiche

Most home cooks bake spinach quiche in a standard 9-inch pie dish, then cut it into 8 wedges. A single wedge in that setup usually falls around 280 to 340 calories, with about 20 grams of fat, 12 or so grams of protein, and mid-teens grams of carbohydrate. That range lines up with nutrition data for “quiche, with spinach,” where one piece equal to 1⁄8 of a 9-inch pie clocks in at about 298 calories and around 20 grams of fat.

Plenty of grocery deli counters and brunch cafés sell dense slices that are taller and creamier than the home version. Those often land far higher. A spinach quiche slice around 190 grams can reach about 500 calories per piece, driven by cream, extra cheese, and a thick pastry shell.

Then you’ve got crustless pans and “skinny” brunch bakes. Public extension recipes built on eggs, cottage cheese, feta, and thawed frozen spinach drop the pastry shell and lean on low-fat dairy. One of those pans lands close to 146 calories per serving with about 10 grams of fat and 11 grams of protein.

Why The Numbers Change

Spinach quiche behaves like a math problem with three main levers: crust, dairy, and slice size. The crust alone can add 100-150 calories to a wedge, since a classic butter crust brings flour and fat without much protein. Rich dairy pulls the total upward fast too. Heavy cream and full-fat cheese mean a silkier center, but they also drive fat grams per slice. A version that trades cream for low-fat cottage cheese, or swaps some cheddar for reduced-fat Swiss, trims dozens of calories in a single serving.

Slice size might be the sneakiest factor. Cutting a 9-inch pie into 6 slices instead of 8 bumps each serving by a third. That’s the difference between something near 300 calories and something that creeps toward 400-plus, even before any cream or bacon shows up.

Spinach Quiche Calories By Style

Style	Calories Per Slice (1/8 Of 9-Inch Pie Or Similar)	Notes On Ingredients
Classic Homemade With Crust	~300–340 kcal	Eggs, milk, cheese, sautéed spinach, standard pastry shell.
Crustless Cottage Cheese Pan	~140–200 kcal	No pastry; eggs plus low-fat cottage cheese and feta, baked in a sprayed pie dish.
Thick Café Slice	~450–500 kcal	Taller wedge; cream and extra cheese, often served warm from a bakery case.

Protein helps keep brunch hunger under control, and spinach quiche delivers more than toast or a muffin because eggs bring about 6 grams of complete protein per large egg for roughly 72 calories, according to USDA FoodData Central. That mix of protein and fat is one reason slices like the crustless cottage cheese version feel filling even around the 150-200 calorie mark.

For meal prep, this same protein logic shows up in high protein breakfast ideas across the site. Eggs, leafy greens, and a salty cheese crumble punch above their calorie count, and that lines up with why spinach quiche keeps showing up on brunch menus.

Serving Size Math For Spinach Egg Pie Slices

Serving size sounds boring, but it quietly decides what lands in your food log. A slim 1⁄8 wedge from a home pan might weigh 130-150 grams and sit near 300 calories. A deli wedge can double that weight, which explains why it can jump toward 450-500 calories in one serving.

Standard 9-Inch Pie

A lot of home recipes stick to four eggs, milk, frozen spinach, and a store-bought crust baked in a 9-inch shell. When you cool the pan and slice it into 8 wedges, each wedge gives you a balance of veggies, dairy, and pastry without blowing past breakfast calories for most folks. That’s why a single wedge often lands near 300 calories, not 500.

If you’re tracking carbs, that same standard wedge carries about 17 grams of total carbohydrate, 12.5 grams of protein, and 20 grams of fat. The crust supplies most of the starch, while the eggs and cheese push protein and fat.

Bigger Cafe Wedges

Walk into a bakery and the slice on your plate might not look like the slim triangle you cut at home. Commercial pans are often deeper, and cooks lean on cream, Swiss, cheddar, or even feta for the silky texture people expect from brunch quiche. That richer dairy base plus a taller pastry wall can lift one wedge to about 500 calories.

That’s not “bad,” it’s just data. If lunch will be lighter, a hearty wedge at 10 a.m. can still work inside your daily calorie intake. The trick is knowing that you just logged breakfast on the same level as a loaded breakfast sandwich.

Macros And Nutrition In Spinach Quiche

Calories tell only part of the story. Spinach quiche carries protein from eggs, calcium from cheese, and iron and vitamin K from leafy greens. Many lighter pans still sit in a sweet spot for protein thanks to eggs and low-fat dairy.

Macro Snapshot Per Slice

Version	Per-Slice Macros	What It Means
Classic With Crust	~300 kcal • ~20 g fat • ~12 g protein • ~17 g carbs	Balanced wedge for brunch or light lunch.
Crustless Low-Fat Dairy Pan	~150 kcal • ~10 g fat • ~11 g protein • ~3 g carbs	Lower calorie bite that still fills you up.
Deep Cafe Slice	~500 kcal • higher fat • higher sodium	Large wedge made with cream and extra cheese.

One pattern stands out: fat grams drop fast when you skip the pastry and swap heavy cream for cottage cheese or lower-fat Swiss. That’s how you get a slice near 146 calories that still brings double-digit protein.

Protein And Fullness

Eggs carry a full set of amino acids, and a large egg runs about 6 grams of protein for around 72 calories. That steady protein drip helps explain why even a light crustless spinach bake tends to hold you till lunch better than plain toast.

Spinach quiche also brings calcium from cheese and leafy greens. Calcium, plus the saltiness of cheese, is part of why brunch feels satisfying without needing a huge plate of potatoes.

How To Make Your Slice Lighter Without Losing Flavor

You don’t have to ditch brunch favorites to dial back calories. The goal is trimming fat where it piles up the fastest, and keeping protein up so the meal still feels steady.

Skip The Pastry Shell

A sprayed glass pie dish gives you structure without puff pastry or butter crust. University of Illinois Extension’s crustless spinach version uses beaten eggs, low-fat cottage cheese, feta, Swiss, frozen spinach, and a hit of nutmeg. One serving lands near 146 calories with about 11 grams of protein, which fits a light breakfast or a snack between meetings. You still get that eggy custard center, just without the flour shell.

Swap Dairy Choices

A traditional quiche often calls for cream. Swapping in milk or even part-skim cottage cheese lowers fat grams per slice. Low-fat cottage cheese blends smoothly once baked, and feta’s salty bite keeps the dish from tasting bland even with less cheddar.

Eggs glue the filling together either way, and a large egg brings protein for about 72 calories. That means you can cut back on cheese volume without ending up with a watery, floppy slice.

Pile In More Greens

Frozen spinach is cheap, already blanched, and easy to squeeze dry. Loading extra spinach into the custard adds volume without many calories, which is the same basic trick used in diabetes-friendly versions from public nutrition programs. The greens also bring iron and vitamin K, two minerals leafy veg are known for.

Safe Storage And Reheating

Leftover egg dishes fall under the same safety rules as other cooked casseroles. Federal food safety guidance says quiche with filling should be kept chilled and eaten within about 3 to 5 days once baked. The USDA also says cooked leftovers should go in the fridge within two hours, then get reheated to 165°F before eating.

For weekday meal prep, that means slice, chill fast in shallow containers, and reheat just what you plan to eat. That routine keeps texture closer to fresh while staying inside basic safety rules.

Bottom Line On Spinach Quiche Calories

A standard home-baked spinach quiche cut into 8 wedges usually lands near 300 calories per slice, with fat and protein coming mostly from eggs and cheese. Drop the crust and lean on low-fat dairy and you can slide toward 150-200 calories while still getting double-digit protein. Grab a tall café wedge loaded with cream and pastry and you’re closer to 450-500 calories.
