Baked Oatmeal That Costs 84 Cents a Serving and Feeds You for Three Days
Breakfast cereal is where shrinkflation hit hardest, which is a little ironic given how much of the shelf it takes up. When the GAO looked at product downsizing, cereal was one of the categories where it showed up most, and the boxes that got smaller turned out to be the ones people actually buy.
Rolled oats did not get that treatment, mostly because a 42-ounce canister of oats is not a product anybody is trying to make exciting. There is no cartoon on the front. Nobody is redesigning the packaging.
This is the thing I make on Sunday when I do not want to think about breakfast again until Wednesday. It bakes in one dish, keeps in the fridge for four days, and reheats in a microwave without turning into wallpaper paste.
What it costs
Ingredient Amount Cost
Rolled oats 3 cups (270 g) $1,02
Whole milk 2.5 cups $0,68
Large eggs 2 $0,36
Apples or frozen berries 2 apples $1,80
Brown sugar or maple syrup 1/3 cup $0,35
Butter 3 tbsp $0,45
Baking powder, cinnamon, vanilla, salt – $0,35
Total 6 servings $5,01
84 cents per serving.
The milk and egg figures come from BLS average price data for June 2026: $4.32 a gallon for whole milk, $2.14 a dozen for large eggs. The rest are my estimates from a normal supermarket, since BLS does not track oats or cinnamon.
For comparison, a single-serve instant oatmeal packet runs somewhere north of 50 cents and gives you about half the food. You are paying for the paper. https://americankitchentales.com/frozen-vs-fresh-produce-the-price-myth-nobodys-debunking/
Ingredients
Serves 6, in a 9×13 inch dish.
- 3 cups old-fashioned rolled oats
- 2.5 cups milk, any kind
- 2 large eggs
- 1/3 cup brown sugar or maple syrup
- 3 tbsp butter, melted, plus a little for the dish
- 2 tsp baking powder
- 1 tsp ground cinnamon
- 1 tsp vanilla extract
- 1/2 tsp salt
- 2 apples, diced, or 1.5 cups frozen berries
Do not use steel-cut oats. They will not soften in the bake time and you will end up chewing gravel. Quick oats work but go pasty. Old-fashioned rolled is the one.
Method
Heat the oven to 350°F (175°C) and butter a 9×13 dish.
Whisk the milk, eggs, sugar, melted butter, vanilla, and salt together in a bowl. Whisk properly, especially if your butter is hot, or you will get scrambled egg threads in your oatmeal.
Stir in the oats, baking powder, and cinnamon. Fold in the fruit, keeping a handful back.
Pour into the dish, scatter the reserved fruit on top, and bake 35 to 40 minutes, until the center is set and the top is golden. A knife in the middle should come out mostly clean. Slightly wet is fine; it firms up as it cools.
Let it sit 10 minutes before cutting. Cutting it hot gives you six piles instead of six squares.

Estimated from USDA reference values, rounded, using whole milk and apples. Skim milk drops it by roughly 25 calories a serving. Cutting the sugar to a quarter cup takes about 20 calories and 5 grams of sugar off each square, and I honestly cannot taste the difference when the fruit is ripe.
Notes
On frozen fruit. Frozen berries are usually cheaper than fresh outside of summer, and in a baked dish the texture difference disappears entirely. Do not thaw them first. Frozen straight into the batter, or they bleed and you get purple oatmeal.
Storage. Cool completely, cover, fridge, four days. It also freezes in individual squares. Reheat with a splash of milk over the top, 60 to 90 seconds in the microwave.
Making it cheaper. Store brand oats and store brand baking powder are chemically identical to the branded versions and usually run 30 to 40% less. Oats in particular have almost no quality gradient. Buy the big canister; the per-ounce price on the small one is a joke.
Making it more filling. Half a cup of peanut butter stirred into the wet mix adds about 8 grams of protein per serving for around 60 cents total. It also makes it taste like a cookie, which is either a feature or a problem depending on your morning.
