Wondering how many calories are in a slice of halibut? This halibut calories per slice calculator gives you a quick estimate based on slice size, number of slices, and how the fish is prepared. Instead of guessing portion sizes, you can choose a thin cut, standard fillet, thick cut, or enter the exact weight of one slice in grams or ounces.
The tool also breaks down the main macronutrients — protein, fat, and carbohydrates — so you can use it for meal planning, macro tracking, or simply staying within a daily calorie target. Halibut is naturally low in fat and high in protein, making it a popular choice for balanced, high-protein meals.
Whether you are counting calories for weight management or building a nutrient-dense diet plan, this calculator turns a vague “one slice” into a clear, usable number. For precise results, weigh your fillet and choose the preparation method that matches how you cook it.
🐟 Halibut Calories Per Slice
Estimate calories and macros for any number of halibut slices, from thin sashimi cuts to thick restaurant fillets.
How to Use This Tool
Start by entering the number of halibut slices you plan to eat. The preset buttons make this quick for one, two, four, or six slices, but you can type any value. Next choose a slice size: thin cuts of about 85 g (3 oz), standard fillet slices of about 113 g (4 oz), thick cuts of about 170 g (6 oz), or a custom weight of your own. If you choose custom, enter the weight per slice in grams or ounces. Then pick the preparation method that best matches how the fish is cooked — raw, baked or grilled, pan-seared with oil, or breaded. The calculator will show total calories, calories per slice, and protein, fat, and carbohydrate totals.
For the most accurate numbers, weigh one slice on a kitchen scale and use the custom weight option. If you prefer to estimate by exact gram amounts, the halibut calories per gram calculator may be a useful companion.
How the Calories Are Estimated
The calculator is based on published food-composition values for halibut expressed as calories and macronutrients per 100 grams of edible flesh. Raw halibut contains roughly 91 kcal per 100 g. Cooking without added fat does not add calories, but it does remove water, so a cooked portion is more calorie-dense per 100 g than the same weight of raw fish. Baking or grilling is listed here at about 111 kcal per 100 g, pan-searing at about 140 kcal per 100 g, and breaded or battered halibut at about 180 kcal per 100 g, depending on the amount and type of coating and oil.
Core formula: total grams of halibut ÷ 100 × calories per 100 g = total calories. The same proportion is used for protein, fat, and carbohydrates.
For example, a 113 g standard slice of baked halibut works out to 113 ÷ 100 × 111, which is about 125 kcal. Multiply by the number of slices to get the full meal total. The macro values in this tool reflect common USDA-style averages for halibut, so individual fillets can vary slightly.
Worked Examples
Example 1 — Two baked standard slices. Two 113 g slices weigh 226 g in total. With 111 kcal per 100 g, total calories = 226 ÷ 100 × 111 = 251 kcal. Protein = 226 ÷ 100 × 22.9 ≈ 51.8 g; fat ≈ 3.6 g.
Example 2 — Four raw thin slices. Four 85 g slices weigh 340 g. With 91 kcal per 100 g, total calories = 340 ÷ 100 × 91 = 309 kcal. Protein = 340 ÷ 100 × 18.6 ≈ 63.2 g; fat ≈ 4.4 g.
Example 3 — One thick pan-seared slice. A 170 g thick cut cooked with a little oil provides 170 ÷ 100 × 140 = 238 kcal, roughly 34.3 g protein and 10.2 g fat.
Reference Values by Preparation
The table below shows the approximate values used by this calculator. Use them as a general guide when planning meals.
| Preparation | Calories (kcal/100g) | Protein (g) | Fat (g) | Carbs (g) |
|---|---|---|---|---|
| Raw / sashimi | 91 | 18.6 | 1.3 | 0 |
| Baked / grilled | 111 | 22.9 | 1.6 | 0 |
| Pan-seared with oil | 140 | 20.2 | 6.0 | 0 |
| Breaded / battered | 180 | 16.1 | 9.8 | 7.5 |
Values are approximate. For the latest official nutrient listings, search for halibut in the USDA FoodData Central database.
Factors That Affect Accuracy
- Slice weight varies more than most people expect. A hand-cut fillet slice can differ by 20 g or more from a serving-size guide, so weighing is the most reliable method.
- Cooking method changes calorie density. Baking and grilling add almost no fat, while butter, oil, marinades, or a flour-and-egg breading add meaningful calories.
- Species and origin matter slightly. Pacific, Atlantic, and Alaskan halibut have similar but not identical nutrient profiles; most USDA data uses a blended average.
- Raw versus cooked weight is different. If you weigh raw fish before cooking, use the raw calorie value; if you weigh the cooked portion, use the cooked value.
Pro tip: For portion control, bake or grill halibut without added oil and weigh it raw. A 4 oz (113 g) raw portion is a lean, satisfying serving that fits easily into most calorie targets.
Frequently Asked Questions
How many calories are in one slice of halibut? A typical baked standard slice (113 g) has about 125 kcal. A thin raw slice (85 g) has about 77 kcal, and a thick pan-seared slice (170 g) has about 238 kcal. The exact amount depends on thickness and cooking method.
Is halibut good for weight loss? Halibut is rich in protein, which helps with satiety, and it is naturally low in fat when cooked without added oil. A high-protein meal can help reduce hunger and support muscle maintenance during a calorie deficit. Just keep in mind that breaded or butter-basted preparations add calories quickly.
Should I track halibut raw or cooked? Use the state that matches how you weigh it. Raw halibut contains more water, so 100 g raw will weigh less after cooking but will not lose calories. This calculator lets you choose the preparation method, so you can track either way.
Can I use this for meal prep? Yes. Calculate total calories for your planned number of slices, then divide across containers. For consistent results, use the custom weight option and weigh each portion after cooking.
