Cauliflower. It’s one of those vegetables that’s quietly taken over kitchens everywhere. You might have noticed it popping up in recipes as a rice substitute, mashed like potatoes, or simply steamed as a side dish. But if you’re watching your calories or just curious about what you’re eating, you probably wonder: how many calories are actually in steamed cauliflower? Spoiler alert—it’s surprisingly low, but there’s a lot more to this humble veggie than just its calorie count.
Let’s dive into what steamed cauliflower really brings to the table, literally and nutritionally. First off, a typical serving of steamed cauliflower—think about three-quarters of a cup or roughly grams—packs around calories. That’s barely anything! To put it in perspective, that’s fewer calories than a small apple or a slice of bread. And here’s the kicker: those calories come mostly from carbs and a little protein, with almost no fat at all.

So why is steamed cauliflower so low in calories? Well, it’s mostly water—like, over 90% water—and fiber, which doesn’t add calories but fills you up. Steaming it is a gentle way to cook, so you’re not adding oils or fats that bump up the calorie count. Unlike frying or roasting with butter or oil, steaming keeps it light and healthy.

But calories aren’t the whole story. Steamed cauliflower is actually pretty impressive when it comes to nutrition. For one, it’s a good source of fiber, which helps keep your digestion on track and can make you feel full longer (always a plus if you’re trying to lose weight). It also has potassium, which is great for your heart and muscles. And even though steaming can reduce some vitamin C compared to eating it raw, there’s still a decent amount left to give your immune system a boost.
Another thing I love about steamed cauliflower is how it fits into almost any diet. Whether you’re keto, paleo, vegan, or just trying to eat cleaner, cauliflower is your friend. It’s low in carbs, fat-free, and naturally gluten-free, so it plays well with all sorts of eating plans.
Diet Type | Why Steamed Cauliflower Works Well |
---|---|
Keto | Low in carbs, helps maintain ketosis if eaten in moderation. |
Paleo | Whole food, unprocessed, nutrient-dense. |
Vegan/Vegetarian | Provides fiber, vitamins, and plant protein. |
Low-Calorie | Very low in calories, perfect for weight loss. |
Gluten-Free | Naturally gluten-free, safe for celiac disease. |
Now, if you’re wondering how steaming stacks up against other ways to cook cauliflower, here’s the scoop. Steaming keeps the calories low and nutrients intact better than boiling or frying. Boiling can leach out some vitamins into the water, and frying? Well, that adds a whole lot of calories thanks to the oil.
Cooking Method | Calories per 100g | Notes |
---|---|---|
Steamed | 20-23 | Preserves nutrients, no added fat. |
Boiled | 23 | Some vitamins lost in water. |
Roasted (with oil) | 50-70 | Higher calories due to oil. |
Fried | 100+ | High fat and calories from oil. |
What’s great is how easy it is to add steamed cauliflower to your meals. You can keep it simple—just steam it and sprinkle some salt, pepper, maybe a squeeze of lemon. Or get creative: pulse it into cauliflower rice, mash it like potatoes, toss it into soups, or add it cold to salads for a bit of crunch. It’s one of those veggies that’s super flexible and always tasty.
