A medium baked potato with skin has about 161 calories and 4.3 grams of protein.
Here’s a clear look at baked potato calories and protein so you can size portions, match toppings, and build a meal that fits your goals. Data below uses USDA-backed figures for a plain, skin-on potato baked without salt.
Baked Potato Nutrition: Quick Reference
The values below reflect plain potatoes. I calculated each line from the same base profile so the numbers scale cleanly across serving sizes.
| Serving | Calories | Protein (g) |
|---|---|---|
| 100 g (reference) | 93 | 2.5 |
| 1 oz (28 g) | 26 | 0.7 |
| Small potato (138 g) | 128 | 3.5 |
| NLEA serving (148 g) | 138 | 3.7 |
| Medium potato (173 g) | 161 | 4.3 |
| 200 kcal portion (215 g) | 200 | 5.4 |
| Large potato (299 g) | 278 | 7.5 |
Source for the base profile: USDA-based baked potato data (medium, 173 g). That page lists 161 calories, 36.6 g carbs, 4.3 g protein, and about 926 mg potassium for a plain, skin-on potato.
What Changes The Numbers?
Size And Water Loss
Potatoes vary in size and moisture. Larger tubers carry more starch, so calories and protein rise with weight. Baking also drives off water, leaving nutrients more concentrated than in boiled potatoes.
Skin On Vs. Off
Most vitamins and minerals sit in the flesh, while the peel supplies roughly half the fiber. Leaving it on keeps more fiber per bite. Calories and protein barely move when the skin is removed.
Salt, Oil, And Add-ins
Plain baked potatoes are naturally low in fat and sodium. Fat, salt, and extra protein come from toppings. That can be handy when you want a more filling plate, or it can push calories higher than planned. The next sections show exactly how to steer it.
How Baked Potatoes Fit A Healthy Plate
One medium potato offers vitamin C, vitamin B6, and ample potassium. It’s a starchy vegetable, so pair it with lean protein and non-starchy veggies for balance. The Harvard Nutrition Source on potatoes explains why prep method matters: baking or roasting with minimal fat keeps energy in check, while deep-fried versions change the picture.
Baked Potato Calories & Protein By Size And Skin
This section breaks down baked potato calories and protein by common portions, plus quick tips for trimming or boosting protein without blowing the budget on calories.
Small To Large: Picking The Right Potato
Small potatoes (about 138 g) land near 128 calories with roughly 3.5 g of protein. Mediums (173 g) sit at 161 calories and 4.3 g protein. Large spuds can double the weight and push past 275 calories with 7–8 g of protein. The table up top lines up those jumps so you can choose by appetite.
Skin Choices
If you prefer a fluffier interior, you might skip the peel. You’ll give up some fiber, but calories and protein barely change because those come from the starch-rich flesh. For a bit more texture and fiber, keep the skin and mash it into the flesh.
Toppings Math For A Baked Potato
Here’s a set of popular toppings with typical portions. Mix and match to hit the protein mark you want.
| Topping (Portion) | Calories | Protein (g) |
|---|---|---|
| Butter (1 tbsp) | 102 | 0.1 |
| Sour cream (2 tbsp) | 50 | 1.0 |
| Cheddar, shredded (1 oz) | 114 | 7.0 |
| Greek yogurt, nonfat (2 tbsp) | 18 | 3.1 |
| Olive oil (1 tsp) | 40 | 0.0 |
| Bacon bits (1 tbsp) | 25 | 2.0 |
| Black beans (1/2 cup) | 114 | 7.6 |
| Steamed broccoli (1/2 cup) | 27 | 1.9 |
Numbers above reflect standard database entries for common dairy, oils, and pantry items. Swaps like nonfat Greek yogurt in place of sour cream raise protein while holding calories down. A modest sprinkle of cheese adds function and flavor; pairing it with beans multiplies protein and fiber fast.
Builds That Hit Your Target
High-Protein, Moderate Calories
Start with a medium potato. Add 1 ounce of cheddar and 1/2 cup black beans. You’re around 161 + 114 + 114 = 389 calories and 4.3 + 7 + 7.6 ≈ 19 g of protein. Finish with chopped scallions and a spoon of salsa for brightness.
Lighter, Tangy, And Filling
Pick a small potato. Mash in 2 tablespoons nonfat Greek yogurt, a squeeze of lemon, and lots of chives. That lands near 128 + 18 ≈ 146 calories with about 3.5 + 3.1 ≈ 6.6 g of protein, plus a creamy bite without heavy fat.
Comfort Style
Choose a medium potato. Add 1 tablespoon butter and 1 ounce cheddar. Expect roughly 161 + 102 + 114 = 377 calories with about 4.3 + 0.1 + 7 ≈ 11.4 g of protein. It’s cozy and rich; add a side salad to balance the plate.
Answers To Common Calorie And Protein Questions
Does Baking Change Protein?
No, heat doesn’t add protein to potatoes. Baking mostly removes water, so grams per 100 g look slightly higher than in a boiled potato, but total protein for the whole potato stays tied to size.
Which Potato Type Should I Bake?
Russet potatoes deliver the fluffiest texture. White or yellow types bake well too, just a bit denser. Nutrition for plain skin-on baked potatoes is broadly similar across these varieties.
What About Sweet Potatoes?
Sweet potatoes offer slightly fewer calories per 100 g, a touch more fiber, and a bit less protein than a white baked potato. They skew sweeter, which also shifts toppings toward savory picks like beans, feta, or yogurt.
How To Bake For The Best Texture
Basic Oven Method
Scrub potatoes and dry well. Prick each potato 4–5 times. Rub lightly with oil if you like a crisper skin. Bake on a rack at 220°C/425°F until the center hits 98–100°C/208–212°F, about 45–60 minutes for mediums. Rest 5 minutes, then split and fluff with a fork.
Microwave Shortcut
If you’re short on time, microwave 4–6 minutes per side for medium potatoes, then finish in a hot oven for 10 minutes to crisp the skin. Texture lands close to oven-only with much less waiting.
Air Fryer Option
Coat lightly with oil, then cook at 200°C/400°F for 35–45 minutes, turning once. This method keeps exteriors crisp and centers fluffy without much added fat.
Protein Boosters That Pair Well
Plain potatoes carry moderate protein for a tuber. To push higher without overdoing calories, lean on beans, cottage cheese, Greek yogurt, or diced roasted chicken breast. Cheese gives a strong bump in small amounts. If you need more staying power, add a pat of butter or a drizzle of olive oil for taste and texture, then round out the meal with a crisp salad.
Smart Swaps And Portion Tips
- Split one large potato across two plates and add a protein-heavy side like beans or grilled fish.
- Try a medium potato with Greek yogurt, herbs, and a spoon of salsa instead of sour cream.
- Grate a sharp cheese so a lighter sprinkle tastes bold.
- Keep salt gentle; a squeeze of lemon and fresh herbs can wake up flavor with no sodium hit.
Where These Numbers Come From
All potato figures trace back to the same dataset tied to USDA FoodData Central. The baked potato entry above lists 161 calories and 4.3 g protein for a 173 g, skin-on potato. I used that per-100 g profile to scale small, large, and custom portions so your math stays consistent.
Recap: Baked Potato Calories And Protein
baked potato calories and protein data helps you plan meals fast. A plain medium potato gives 161 calories and about 4.3 g protein. Size, skin choices, and toppings shift the total. Use the quick tables, pick a build, and eat the potato that fits your day today.
