How Many Calories Are In Homemade Scalloped Potatoes? | Batch Math Guide

Calories In A Pan Of Scalloped Potatoes — Tested Batch Math

Let’s pin the numbers to a standard kitchen pan so you can portion smart. The batch below reflects a common home tray: russet slices layered in a light roux with a modest cheddar blanket. The total comes out near 1,700 calories for the whole dish, which lines up with a 210–290-calorie side serving depending on scoop size.

Ingredient Set Used For The Calculation

This template mirrors what most home cooks make on weeknights. You can tweak cheese or milk and use the adjustment tips later.

Pan Breakdown (Ingredients • Amount • Calories)

Ingredient	Amount	Calories
Russet potatoes, sliced	900 g (about 2 lb)	≈ 711 kcal
Whole milk	480 g (2 cups)	≈ 288 kcal
Cheddar cheese, shredded	113 g (1 cup packed)	≈ 455 kcal
Butter	28 g (2 Tbsp)	≈ 201 kcal
All-purpose flour	16 g (~2 Tbsp)	≈ 58 kcal
Total, whole pan	—	≈ 1,713 kcal

Those potato slices carry most of the weight, while cheddar and butter add dense energy in a small volume. Once you set your daily calorie needs, these tray totals make portioning easy at dinner.

Where The Ingredient Numbers Come From

Values are pulled from widely used nutrition databases built on lab-analyzed foods. For the tubers, see the potato entry (per 100 g). Whole milk lands near 60 kcal per 100 g; cheddar sits around 400 kcal per 100 g; and butter is roughly 717 kcal per 100 g—each based on standard full-fat versions and typical shredded cheese density. These references reflect USDA-linked datasets and give a tight baseline for home math.

How Serving Size Changes The Calories

Once the tray total is fixed, the rest is slicing the pie. If the pan feeds six, each plate gets more energy than if the pan feeds ten. Cheese-forward styles push the per-cup number up, while a leaner sauce brings it down.

Per-Serving Estimates By Pan Yield

Pan Portions	Per Serving Calories	Macros (C/F/P, g)
6 servings	≈ 285–295 kcal	32 / 13 / 11
8 servings	≈ 210–220 kcal	24 / 10 / 8
10 servings	≈ 170–180 kcal	19 / 8 / 6

What Pushes The Number Up Or Down

Cheese Level

Doubling the cheddar adds about 450 more calories to the tray. That’s ~45–75 extra per plate depending on how many people you’re serving.

Milk Choice

Swapping whole milk for 2% trims about 20 calories per 100 g of milk used. With two cups in the sauce, the pan sheds roughly 90–100 calories total.

Butter Amount

Each tablespoon brings ~100 calories. If your roux already coats the slices smoothly, you can hold back a spoon without losing texture.

Slice Thickness

Thinner rounds pack more potato per scoop; chunkier cuts leave more air gaps. Same ingredients, different density on the plate.

Make Your Own Nutrition Estimate, Step By Step

This quick method keeps you within a small margin of error while you cook.

1. Weigh the potatoes. A cheap digital scale pays for itself. Note grams or pounds before slicing.
2. Measure the dairy. Track milk in cups and weigh cheese if possible.
3. Log the butter and flour. Two tablespoons of each is common for a light sauce.
4. Grab per-100-gram values. Potatoes, milk, cheddar, and butter all have stable entries in USDA-linked datasets like MyFoodData. Multiply by your weights to get totals.
5. Add everything up. That’s your pan total. Divide by servings for the plate number.

Sodium And Smart Seasoning

Cheese and salted butter add sodium alongside flavor. If you’re watching intake, the current sodium advice points to keeping the day’s total within moderate limits. Lean on onion, garlic, black pepper, and fresh herbs to brighten the pan without leaning hard on the shaker.

Macronutrients: What You’re Getting

Carbohydrates

Potatoes are mainly starch, and the flour roux adds a little more. A side scoop typically lands in the 19–32 gram range shown above; pair with non-starchy vegetables or a lean protein to balance the plate.

Protein

Cheddar and milk contribute most of the protein. Expect ~6–11 grams per serving in common portion sizes.

Fat

Butter and cheddar drive the fat number. Tweak the amount of each to match your goals while keeping the sauce silky.

Ways To Lighten The Dish Without Losing Comfort

Dial Down The Cheese

Use a sharper cheddar so a smaller handful still tastes bold. Sprinkle a thin top layer and skip a heavy middle layer.

Swap The Dairy

Try 2% milk and thicken with a slightly longer simmer. You’ll keep the creamy texture and shave calories from the pan total.

Trim The Butter

One tablespoon in the roux plus a quick brush on top can be enough for browning and flavor.

Add Volume With Veg

Fold in thinly sliced onions or a handful of blanched greens between layers. Same pan size, fewer calories per scoop.

Method Notes: Consistent Results At Home

Slice Evenly

Uniform ⅛–¼-inch rounds cook through at the same pace. That steadiness helps serving size stay consistent too.

Simmer The Sauce

Cook the roux for one minute, whisk in warm milk, and simmer until it lightly coats the spoon. A stable sauce spreads calories evenly across the tray.

Layer And Cover

Arrange two layers of potatoes, a modest pour of sauce, and a light sprinkle of cheese. Cover for most of the bake to keep moisture, then finish uncovered for color.

Ingredient Reference Points You Can Trust

When you want precise figures, databases that compile USDA analyses are your friend. Potato values and dairy entries in those tools give dependable per-100-gram numbers that translate neatly to home weights. Pick the variant that matches your carton or block and stick to that line for repeatable math.

Frequently Missed Tweaks That Change Calories Fast

Pan Size And Depth

Switching to a deeper 8×8 changes density and serving size. If you keep the same ingredient list, your calories per cup will look higher simply because the scoop is fuller.

Oil Sprays And Toppings

A generous oil spray or breadcrumb cap adds energy that often goes uncounted. Measure or weigh before you sprinkle.

Salt Content Of Cheese

Some brands run saltier than others. If you’re steering toward a moderate daily target, taste before adding extra salt to the sauce.

Putting It On The Plate

Serve alongside roast chicken or baked fish and a pile of green veg. The plate stays balanced, and your side can sit in that ½- to ¾-cup sweet spot without crowding out protein or fiber.
