How Many Calories Are in Spinach, Raw or Cooked? Raw vs. Cooked

A 100-gram serving of raw leaves provides about 23 calories, while plain cooked spinach provides roughly 20 to 25. A 30-gram serving supplies roughly 7 calories before any oil, butter, cheese, or sauce.

You’ll get a clearer food log by comparing portion weight, water content, cooking methods, and added ingredients. This guide covers spinach nutrition facts and practical measurements for salads, steamed vegetables, and cooked meals.

Raw Spinach Sets the Low-Calorie Baseline

A 30-gram portion of raw spinach supplies about 7 calories, according to the 23-calorie figure for 100 grams. That low energy count lets you build a large salad without making spinach the main calorie source.

USDA FoodData Central lists raw spinach at about 23 calories per 100 grams. Its high water content contributes to that figure, while vitamins and minerals increase its nutrient density without adding comparable energy.

Raw spinach provides folate, vitamin K, and vitamin C. Those nutrients make the leaves useful for salads and side dishes, although nutrient amounts vary with freshness, storage, and preparation.

Weight and volume provide useful reference points

You get better control by weighing spinach than by estimating a cup. A loosely packed household cup can sit near 30 grams, but tightly packed leaves may weigh more and raise the calorie estimate.

Your scale gives you a reproducible serving. Record the same 30-gram amount each time, and you can compare raw leaves with cooked portions without confusing volume changes for differences in calorie content.

Cooked Spinach Changes Weight Rather Than Adding Calories

Plain boiling or steaming leaves adds no calories by itself. Heat softens the spinach and changes its water content, so 100 grams of plain cooked leaves still contain roughly 20 to 25 calories.

One cup of cooked spinach contains about 40 calories, but that cup does not correspond to one raw cup. Drained leaves pack more tightly, and the final weight depends on retained water and cooking time.

Your calorie total changes mainly through preparation. Water contributes no calories, while olive oil, butter, cheese, cream, and sauce can add substantial energy to the same portion of leaves.

Preparation determines the comparison

Boiled spinach entries generally describe the plain vegetable after draining. The calorie total varies with retained water and cooking method, so “cooked spinach” alone doesn’t identify the exact portion you eat.

For example, 100 grams of plain steamed spinach contains about 23 calories. One teaspoon of olive oil contributes roughly 40 calories, bringing the combined serving to about 63 calories.

That example separates the spinach from the fat added in the pan. Without measuring the oil, you could attribute a higher dish total to the leaves rather than the cooking fat.

“Log spinach separately from cooking fat so your food record shows the energy supplied by each ingredient.

Water Loss Makes Volume Comparisons Misleading

The leaf mass changes during cooking, which makes equal-looking cups unreliable. A loose cup of raw spinach contains air between delicate leaves, while a cooked cup holds denser, wilted spinach with less visible space.

Boiling also removes some water from the leaves. That loss can reduce the drained weight, so a 100-gram raw portion may become a smaller amount of plain cooked spinach.

Suppose you start with 100 grams of raw spinach. After boiling and draining, the edible portion could weigh about 30 to 50 grams and contain roughly 5 to 12 calories.

A cup reverses part of the visual loss because packed cooked leaves take up less space. That higher cup total reflects a different serving weight, not calories created by heat.

Your strongest comparison uses the same starting weight and no added fat. Measure the spinach after draining so water loss and leaf shrinkage don’t distort the result.

Calories per 100 grams offer another useful check. You can compare the raw and cooked figures without relying on cups, which vary in packing density and retained moisture.

Cooking Ingredients Can Raise the Dish Total

One tablespoon of olive oil adds about 120 calories, more than several cups of raw spinach. A small amount of fat can therefore produce a much higher dish total than the leaves alone.

Your food record needs to reflect that difference. Track oil, butter, cheese, cream, and sauce separately so the spinach entry continues to describe the vegetable rather than an entire prepared dish.

Separate the vegetable from the additions

Boiled and drained leaves give you the simplest baseline for tracking plain spinach. Sautéed spinach can include oil or butter, while a creamed preparation can add dairy and a thickener.

• ▸Measure pan fats: Record the oil or butter amount before cooking, even though some fat remains in the pan.
• ▸Count sauces separately: Cream, cheese sauce, and salad dressing contribute more calories than plain leaves.
• ▸Check serving weight: A restaurant plate can contain more fat than the teaspoon listed in your food log.
• ▸Drain the leaves: Excess liquid can carry dissolved fat and seasonings from the cooking pan.
• ▸Name the method: “Boiled, drained spinach” gives you more detail than an entry labeled only “spinach.”

MyFitnessPal can help organize your log, though the selected entry must match your food. A plain boiled spinach record won’t represent a skillet meal made with two teaspoons of butter.

You also need to separate the leaves from prepared dishes. A creamed spinach entry includes dairy and other additions, so using it for plain steamed leaves overstates the vegetable total.

Once added ingredients are separated from the spinach itself, weighing the prepared serving gives you a reliable calorie total.

A Practical Serving Method for Calorie Tracking

Put your bowl on a kitchen scale and tare it before adding spinach. A 30-gram raw portion supplies about 7 calories and gives you a repeatable baseline for salads and side dishes.

Your cooked entry needs a different reference. Weigh the drained leaves, record the cooking method, and list any fat or sauce that reaches the plate.

Use this four-step tracking routine

1. 1Weigh the raw leaves: Record the amount before washing, cooking, or adding other ingredients.
2. 2Choose your method: Label the spinach as raw, boiled, steamed, microwaved, or sautéed.
3. 3Record fat and sauce: Measure each teaspoon of oil, pat of butter, and serving of cheese, cream, or dressing.
4. 4Measure after draining: Record the edible cooked weight after excess liquid has been removed.

Your goal is a portion you can reproduce at the next meal. A consistent 30-gram raw reference is easier to apply than an estimated bowl, while a cooked portion should reflect its drained weight.

You can pair that spinach portion with 100 grams of chopped tomatoes, 90 grams of cooked quinoa, and 100 grams of grilled chicken. Recording each amount separately gives you a more complete meal total.

Build meals from measured amounts

A 30-gram spinach portion fits beside measured servings of vegetables, grains, and protein. Your food log then shows the calorie contribution of each component rather than placing everything under a vague salad entry.

A tightly packed cooked cup differs from a loosely filled raw cup. You shouldn’t treat those measures as equivalent, because the cooked cup contains more leaf mass and less air.

A 30-gram raw serving is useful for comparing portions, but a weighed cooked serving is better for a dish such as boiled, drained spinach. Your scale handles the weight change that a cup measure can hide.

Choosing Raw or Cooked Spinach for Your Meal

Raw leaves give you more volume for about 7 calories per 30 grams. Cooked leaves take up less space and can be easier to measure, but your portion depends on the method and retained water.

Your choice can follow the meal. Choose raw spinach for salad bulk, plain boiling or steaming for a drained side dish, or sautéing for a softer texture with measured oil.

Raw spinach works well in large, light portions

Raw spinach adds color, texture, and volume to a salad without contributing much energy. A 30-gram portion supplies about 7 calories, leaving room for dressing and other ingredients in your meal budget.

Raw leaves provide vitamin K, folate, and vitamin C. Fat-soluble vitamin K absorption improves when you eat spinach with olive oil or avocado, though those additions raise the dish total.

Your salad can still stay light without relying on an exact volume estimate. Weighing the leaves lets you add dressing separately and compare your serving with the 30-gram reference.

Boiled or steamed leaves keep the vegetable total low

Boiling or steaming gives you a cooked side without added fat. Drain the leaves, weigh the edible portion, and record plain cooked spinach using the prepared weight.

Heat can lower vitamin C and folate, while water-soluble nutrients can move into cooking water. Minerals such as iron remain in the leaves, although plant iron is harder to absorb than iron from animal foods.

Cooking also changes portion weight. That difference matters for your log because a drained 30-gram serving does not represent the same starting amount as 30 raw grams.

Sautéed spinach works when the oil is measured

Sautéing adds a richer flavor and softer texture, but oil becomes part of the dish’s calorie total. Measure the fat, record it, and include it beside the spinach entry.

You can retain the vegetable’s nutrient density while controlling the added energy. Boiled and drained spinach remains the plain baseline; measured oil supplies the difference between that baseline and a skillet meal.

Raw and cooked forms both support a low-calorie meal when you measure the portion. Count the leaves, cooking method, oil, butter, cheese, and sauce separately for the most useful total.

Key Takeaways

Your most accurate spinach entry matches the food on your plate. Use about 23 calories per 100 grams for raw leaves or about 20 to 25 for plain cooked spinach, then adjust for serving weight and added fat.

Weighing gives you the strongest portion control. A clearly named cooking method and separate entries for oil, butter, cheese, and sauce provide the context needed to compare raw and cooked spinach calories accurately.
