Hash—whether canned corned beef hash, homemade skillet hash, turkey hash, or a plant-based lentil version—is a hearty breakfast staple. But serving sizes vary widely, and the calorie count changes with the type of hash you choose and the add-ons you pile on. This calculator estimates calories per serving from the hash's calorie density and your selected weight, then adds up common toppings like fried eggs, cheese, butter, or ketchup.
This tool is useful for anyone tracking calories or macros: meal prep planners, home cooks, people following flexible dieting, or anyone curious about portion sizes. Enter your serving weight, choose a hash type, tick any add-ons, and get an instant estimate of total calories plus a protein, carbs, and fat breakdown.
All values are based on standard USDA nutrition data and typical recipes, so they are a close estimate—not a lab measurement. Use the quick-fill buttons for common canned-hash portion sizes, and switch between grams and ounces to match your food scale.
🥘 Hash Calories Per Serving Calculator
Estimate calories and macros for corned beef hash, turkey hash, and plant-based hash, plus common add-ons.
📊 Results
Quick Start
Select a hash type from the dropdown, enter your serving weight in grams or ounces, and tick any add-ons you used. Press Calculate to see total calories and macros. The quick-fill buttons set common canned-hash portions: half a cup (113 g), three-quarters of a cup (170 g), and one cup (227 g). You can also weigh any portion on a kitchen scale and type it directly. For packaged hash, check the label first: if your can lists a different calorie density than the dropdown, you can still use the calculator by selecting the closest type and adjusting the serving weight.
How the Estimate Is Calculated
Each hash type in the tool is represented by a calorie density and macro profile per 100 grams. The serving calories are found by scaling that density by the entered weight:
Protein, carbohydrate, and fat are scaled the same way, then any checked add-on values are added.
Values are based on standard USDA food data and common recipe proportions. Canned corned beef hash averages about 220 kcal per 100 g, with roughly 12 g protein, 14 g carbohydrate, and 14 g fat. Homemade corned beef hash is usually a bit leaner at about 180 kcal per 100 g because it contains more potato and less rendered fat. Turkey hash comes in around 150 kcal per 100 g, while vegetarian lentil hash supplies more carbohydrate and less fat at about 140 kcal per 100 g.
Worked Examples
Example 1 — Canned hash, 170 g: For 170 g (about 3/4 cup) of canned corned beef hash with no add-ons, scale the density: 220 × 170 ÷ 100 = 374 kcal. Protein = 12 × 1.7 = 20.4 g; carbs = 14 × 1.7 = 23.8 g; fat = 14 × 1.7 = 23.8 g.
Example 2 — Turkey hash with egg: A 113 g serving of turkey hash starts at 150 × 113 ÷ 100 ≈ 170 kcal. Add one large fried egg (90 kcal) and the total rises to about 260 kcal, with roughly 25 g protein and 15 g fat.
Example 3 — Homemade hash with cheddar: For 227 g (about 1 cup) of homemade corned beef hash, the base is 180 × 227 ÷ 100 ≈ 409 kcal. Adding 1/4 cup shredded cheddar (115 kcal) brings the total to about 524 kcal.

|---|---|---|---|---|
| Canned corned beef hash | 220 | 12 g | 14 g | 14 g |
| Homemade corned beef hash | 180 | 11 g | 11 g | 10 g |
| Turkey hash | 150 | 14 g | 9 g | 7 g |
| Vegetarian lentil hash | 140 | 10 g | 16 g | 4 g |

Common Mistakes to Avoid
Using dry weight for hydrated ingredients. If you make hash from dried potatoes or pre-cooked meat, the calorie density changes after rehydration. Weigh the final cooked hash only.
Ignoring cooking fat. Fork-tender hash often needs oil or butter in the pan, and that fat adds 100–200 kcal per tablespoon. If you use a generous amount, add it as an add-on or manually include it in your count.
Assuming all cans are the same. A 15 oz can of corned beef hash usually contains about 425 g total, but not all of it is eaten as one serving. The label may state serving size as 1 cup or 3 oz; convert to your actual portion.
Frequently Asked Questions
How accurate is this calculator? It gives a useful estimate for meal tracking, but hash can vary by brand, recipe, and cooking method. Canned hash labels often list between 200 and 240 kcal per 100 g, while restaurant hash may contain more oil. If the package provides different numbers, those are more accurate.
Are the add-on values exact? No. They represent typical USDA portion sizes: one large fried egg (about 90 kcal), 1/4 cup shredded cheddar (about 115 kcal), 1 tablespoon butter (about 102 kcal), and 1 tablespoon ketchup (about 17 kcal). Different brands and preparation methods change the numbers slightly.
Should I weigh hash before or after cooking? Weigh after cooking for the best estimate of what is on your plate. Raw ingredients lose water during cooking, so a raw weight will not match the density values in the calculator.
