Substitute for 12 oz Evaporated Milk: Easy Options

If you need a substitute for a 12-ounce can of evaporated milk, gently simmer 3 cups (710 ml) of whole milk until it reduces to 1½ cups (355 ml). This homemade version works well in soups, sauces, casseroles, and baking; for the fastest option, you can also use an equal volume of half-and-half, with a slightly richer result.

Ingredients

3 cups (710 ml) whole milk

Instructions

Pour the milk into a heavy-bottomed saucepan. A wider pan encourages evaporation, but a smaller, deep pan is less likely to splash; either works as long as you keep an eye on the milk. Use a pan with enough room for the milk to bubble without coming close to the rim.
Set the pan over medium heat and warm the milk until it is steaming, with a few small bubbles beginning to form around the edge. Do not let it come to a rolling boil. Once milk boils vigorously, it can foam over, scorch on the bottom, or develop a cooked flavor.
Lower the heat to maintain a gentle simmer. Cook uncovered for about 30–35 minutes, stirring and scraping the bottom and sides every few minutes with a heatproof spatula or wooden spoon. If a skin forms, stir it back in or lift it off; removing it gives the finished milk a smoother texture.
Begin checking the volume after about 25 minutes, since the rate of evaporation depends on the pan and burner. Take the pan off the heat before carefully measuring: the target is 1½ cups (355 ml), equivalent to 12 fluid ounces. If there is more, return it to a gentle simmer and check again after a few minutes. If it has reduced below the target, stir in a little milk to bring it back to volume.
Use the evaporated milk warm in a recipe that calls for it, or let it cool before measuring and storing. It should look creamier than ordinary milk but still pour easily. Do not add sugar: this is unsweetened evaporated milk, not sweetened condensed milk.

Tips

Measure by volume for a can substitution. A standard 12-fluid-ounce can holds 1½ cups (355 ml). If a recipe says “one 12-ounce can,” this is the amount to replace. A scale reading of 12 ounces by weight is not always the same measurement; use the recipe’s stated can size or volume when possible.
Keep the simmer gentle. A few small bubbles are enough. High heat does not make this substitution better; it can cause scorching and a layer of milk solids on the pan. Stir more often as the level drops, and reduce the heat if the bottom begins to catch.
Whole milk gives the closest everyday result. Lower-fat milk can be reduced the same way, but the finished substitute will taste less rich and may feel thinner in a creamy soup or custard. Do not use flavored or sweetened milk unless you want its flavor and sugar in the finished dish.
Plan for the recipe, not just the can. This homemade version is best when you have time to simmer and can watch the pan. For a quick sauce or casserole, an equal volume of half-and-half is convenient; for delicate baking, consider how its extra fat may affect tenderness and richness.

Serving Suggestions

This substitute is an ingredient rather than a drink to serve on its own. Stir it into the recipe wherever the evaporated milk is called for: use the full 1½ cups (355 ml) in pumpkin pie filling, creamy baked pasta, chowder, macaroni and cheese, or a savory casserole. In soups and sauces, add it gradually over low or medium-low heat and stir until smooth. It brings more body than ordinary milk because simmering concentrates the milk solids, though it will not taste quite as uniform as a commercially processed can.

For a dish that will be baked, you can usually use the homemade milk as soon as it has reached the target volume. If a recipe calls for room-temperature ingredients, cool the substitute first so it does not warm eggs or melt butter prematurely. If the recipe specifies that the evaporated milk should be cold, refrigerate it until chilled before adding it. Follow the recipe’s own seasoning and sweetener amounts; this substitute is plain and unsweetened.

Variations

Half-and-half, no simmering: Replace 12 fluid ounces with 1½ cups (355 ml) half-and-half. It is richer and generally less concentrated in milk solids than evaporated milk, so it works especially well in creamy soups, sauces, and casseroles. In a pie or other baked custard, expect a slightly different texture; the recipe may set more softly or taste richer.
Milk and cream: Mix 1 cup (237 ml) whole milk with ½ cup (118 ml) heavy cream to make 1½ cups (355 ml). This is a quick, rich substitute for a sauce or casserole. It has more fat than evaporated milk, so it can make a dish heavier; use it where that extra richness fits rather than in a recipe where a precise low-fat result matters.
Two-percent or skim milk: Reduce 3 cups (710 ml) of either milk to 1½ cups (355 ml) using the same method. The amount is the same, but the result will be less creamy than the whole-milk version. Keep the heat low and stir frequently because lower-fat milk can still scorch and may form a skin.
Dairy-free option: Use 1½ cups (355 ml) unsweetened, unflavored oat milk or soy milk as a direct-volume swap when the recipe can tolerate a change in taste and body. These products do not all reduce like dairy milk, and some can separate or become thick when simmered. For the most reliable result, use an unsweetened product labeled for cooking and substitute it without reducing; check that its flavor suits the dish.
Coconut milk: Use 1½ cups (355 ml) canned, unsweetened coconut milk for a dairy-free creamy option. It adds a noticeable coconut flavor and can change the character of a pie, soup, or sauce, so it is a better fit when that flavor complements the other ingredients. Stir the can well before measuring because the thick cream and liquid may have separated.

Storage and Reheating

Cool the homemade evaporated milk promptly, transfer it to a clean, covered container, and refrigerate within 2 hours of cooking. Use it within 3–4 days. It may look slightly separated after chilling; stir or whisk it until smooth before using. Do not leave it at room temperature for extended storage, and do not try to preserve it by canning.

To reheat a portion, warm it gently in a small saucepan over low heat, stirring often, just until it is fluid and warm. Avoid boiling it, which can make the milk stick or develop a cooked taste. You can also warm it in the microwave in short intervals, stirring between each one. If it is being added to a cooked dish, it is often easiest to reheat it as part of that dish rather than separately.

Freezing is possible, but thawed milk may separate or become grainy, so it is less suitable for smooth sauces and custards. If you freeze it, use a freezer-safe container with room for expansion, thaw it in the refrigerator, and whisk well before using. For the best texture, make a fresh batch when the substitute will be a prominent part of a creamy or baked recipe.

Frequently Asked Questions

How much homemade evaporated milk does this make?

The recipe starts with 3 cups (710 ml) of whole milk and reduces it to 1½ cups (355 ml), or 12 fluid ounces. That is the amount used in place of one standard 12-fluid-ounce can. Check the volume before using rather than relying only on the cooking time, because a wide pan can reduce milk more quickly than a narrow one.

Can I use regular milk instead of evaporated milk without reducing it?

You can, but it will be thinner and less concentrated. Using 1½ cups (355 ml) of regular milk for a can of evaporated milk may make a sauce or filling less creamy or cause a baked recipe to set differently. For the closest simple replacement, simmer 3 cups (710 ml) down to 1½ cups (355 ml), or choose half-and-half if you need a faster option.

Is evaporated milk the same as sweetened condensed milk?

No. Evaporated milk is unsweetened milk with some of its water removed. Sweetened condensed milk is concentrated milk with a substantial amount of sugar added, so it is thick and sweet. Do not use condensed milk as a direct replacement in savory food or in a recipe that expects unsweetened evaporated milk; it will change both sweetness and texture.

Can I make this with skim milk or lactose-free milk?

Skim milk can be reduced in the same way, though the finished substitute will be less rich than one made with whole milk. Lactose-free dairy milk can also work, but its sweetness may be more noticeable after reduction, and it can scorch if heated too strongly. Keep either milk at a gentle simmer, stir regularly, and stop when it reaches 1½ cups (355 ml).

What should I use if I do not have time to simmer milk?

Use 1½ cups (355 ml) of half-and-half for a quick, creamy swap. A mixture of 1 cup (237 ml) whole milk and ½ cup (118 ml) heavy cream is another option, though it is richer. If the recipe is dairy-free, use 1½ cups (355 ml) of suitable unsweetened oat, soy, or coconut milk, understanding that each changes the flavor and may not behave exactly like dairy.

Why did my milk scorch or form a skin?

Scorching usually means the heat was too high, the pan was too thin, or the milk was not stirred often enough. Move the pan off the burner if you smell burning; do not scrape a scorched layer into the milk, since it can make the whole batch taste burnt. A skin is common as milk reduces. Stir it in for a slightly less smooth result or lift it off before measuring.
