Lower-Fat Substitute for Heavy Cream (Easy Recipe)

This lower-fat substitute for heavy cream combines low-fat milk and cornstarch into a smooth, pourable mixture for soups, sauces, and casseroles. It thickens as it heats, so it can stand in for cream in many savory recipes, but it will not whip or behave like high-fat cream in every dish.

Ingredients

1 cup (240 ml) cold 1% or 2% milk
1 tablespoon (8 g) cornstarch

Instructions

Pour about 3 tablespoons (45 ml) of the cold milk into a small bowl. Whisk in the cornstarch until the mixture is completely smooth, with no dry pockets or lumps. Keep the remaining milk nearby. Mixing the starch with cold milk first is important: adding dry cornstarch directly to hot milk can leave stubborn lumps.
Pour the remaining milk into a small saucepan and warm it over medium heat, whisking occasionally, until it is steaming but not boiling. This usually takes about 2 to 3 minutes for this amount. A vigorous boil is unnecessary and can make milk scorch on the bottom of the pan.
Whisk the cornstarch slurry once more, then pour it gradually into the warm milk while whisking constantly. Continue to cook for about 1 minute, until the mixture lightly coats a spoon and looks smooth. Keep it at a gentle simmer rather than a rolling boil.
Take the pan off the heat. Use the substitute promptly in a recipe calling for about 1 cup (240 ml) of heavy cream, or let it cool briefly before storing. It will thicken a little more as it cools; whisk it again before using if it has settled.

Tips

Choose the milk for the job. Two-percent milk gives a rounder, slightly richer result than 1% milk, while skim milk makes a leaner, less creamy substitute. The cornstarch supplies body, not the richness or flavor of the fat in heavy cream, so choose the higher-fat milk option if you want a closer texture while still using less fat than cream.
Keep the heat gentle. A hard boil can cause scorching and may make a starch-thickened mixture overly thick or uneven. Whisk across the bottom and corners of the saucepan as it warms. If it becomes thicker than you want, whisk in milk a tablespoon (15 ml) at a time until it is pourable.
Temper before adding to a hot dish. For a soup or sauce that is already very hot, whisk a few spoonfuls of the hot liquid into the substitute first, then stir the warmed mixture back into the pot. This gradual change in temperature helps the dairy blend smoothly. Avoid adding it to an acidic sauce all at once; tomato, wine, and lemon can make milk proteins curdle, especially at high heat.
Use it where thickening is useful. This mixture is best in cooked savory dishes where a little starch is welcome. It is not suitable for whipping, and it may not work in recipes that depend on cream’s fat for structure, tenderness, or a glossy finish. The best result comes from choosing a recipe that is meant to be creamy rather than expecting this mixture to duplicate every property of heavy cream.

Serving Suggestions

Stir the substitute into blended vegetable soup, chowder, or a pot of potato soup near the end of cooking. Add it gradually, then heat the soup gently until it is hot and evenly thick. For a skillet sauce, take the pan off the hottest part of the burner before whisking the mixture into the cooking liquid. It adds a creamy-looking consistency without requiring a full cup of heavy cream.

It also works in casseroles and savory pasta dishes when the recipe needs a modest amount of creamy sauce. For example, whisk it into a small amount of warm broth, then combine that with cooked vegetables or pasta before baking. Because the mixture is less rich than cream, season the finished dish thoughtfully: a little salt, black pepper, herbs, or grated cheese can help balance the lighter mouthfeel. Add seasonings to the dish rather than assuming the substitute itself will taste rich or buttery.

For a recipe that calls for cream in coffee, tea, or a cold dessert, this cooked, starch-thickened mixture is usually not the best match. It can taste floury or gel-like when chilled, and it does not have the smooth, fatty texture people expect from cream in a drink. Use milk directly if a thinner result is acceptable, or choose a product specifically intended for the cold application.

Variations

Use 2% milk for extra body: The method and quantity stay the same, but the result tastes a little fuller than a version made with 1% milk. It is still much less rich than heavy cream and is useful when the sauce needs a more substantial feel.

Make it dairy-free: Unsweetened, unflavored soy milk is generally the most practical plant-based choice for a savory sauce because it has a more substantial body than many rice or almond drinks. Use 1 cup (240 ml) soy milk and 1 tablespoon (8 g) cornstarch, following the same method. Check that the carton is unsweetened; vanilla or sweetened varieties can make a savory dish taste out of place. Plant-based milks differ in how they thicken and tolerate heat, so warm gently and follow the carton’s cooking guidance.

Use arrowroot instead: Replace the cornstarch with 1 tablespoon (8 g) arrowroot powder and mix it with cold milk in the same way. Arrowroot can make a smooth, glossy sauce, but it does not always hold up as well through extended cooking or reheating. Avoid a long boil, and add it near the end of cooking.

For a tangy finish: If the recipe suits a slightly tart flavor, you can stir plain, low-fat Greek yogurt into the finished dish instead of cooking it in the saucepan. Start with a few spoonfuls, loosen it with warm sauce, and then fold it in off the heat. Yogurt is not a direct one-to-one replacement in every recipe, and boiling it can cause curdling, so use this option only when its tanginess fits the dish.

Storage and Reheating

Use the substitute fresh when possible, since it can thicken further and become slightly pasty as it sits. If you need to prepare it ahead, transfer it to a clean, covered container and refrigerate it within 2 hours of cooking. It keeps for up to 3 days in the refrigerator. Stir or whisk it before using; if it has set firmly, loosen it with a small splash of milk.

Reheat only what you need in a small saucepan over low heat, whisking frequently and adding milk as needed to restore a pourable texture. Do not let it scorch or boil hard. For leftovers that contain the substitute as part of a cooked dish, refrigerate within 2 hours and use within 3 to 4 days. Reheat leftovers to 165°F (74°C), stirring so the dish heats evenly. Freezing the prepared substitute is not recommended: thawing can separate the milk and leave the starch mixture grainy. If it has been left at room temperature for more than 2 hours, discard it.

Frequently Asked Questions

Can I replace heavy cream with this mixture in equal amounts?

In many cooked soups, gravies, and sauces, you can use about 1 cup (240 ml) of this mixture for 1 cup (240 ml) of heavy cream. The finished dish will be less rich, and its texture may be more starch-thickened than silky. Start with a little less if the recipe is already thick, then add more to taste. A direct swap is not dependable in baking, candy-making, whipped toppings, or recipes where cream’s fat is essential.

Will this substitute whip into peaks?

No. Whipping cream forms peaks because its high fat content allows it to hold air. Milk and cornstarch do not have enough fat for that structure, even after the mixture is chilled. Use a product made for whipping if the recipe needs whipped cream, or choose a different topping that is designed to be served without whipping.

Can I use it in baking?

Sometimes, but not as a universal one-to-one replacement. Heavy cream contributes fat and liquid, and those ingredients affect tenderness, moisture, and browning in baked goods. This substitute adds starch and less fat, so it can change a cake, custard, or scone’s texture. It is more dependable in a savory casserole or a baked dish with a sauce than in a recipe where cream is a major part of the batter.

Why did my mixture turn lumpy or too thick?

Lumps usually form when cornstarch is added dry to hot liquid or when the cold slurry is not smooth before it goes into the pan. Whisk the starch into cold milk first, then pour it in gradually while whisking. If the mixture is smooth but too thick, whisk in milk a tablespoon (15 ml) at a time. If small lumps remain, strain it through a fine-mesh sieve before adding it to the dish.

Can I add it to tomato soup or a lemony sauce?

Yes, but use gentle heat and add it slowly. Acidic ingredients can make dairy proteins curdle, especially if the sauce boils. Temper the substitute with a little hot soup or sauce, stir it back into the pan off the strongest heat, and avoid boiling afterward. If a recipe is strongly acidic or needs prolonged simmering, a non-dairy alternative suited to cooking may be more reliable.

What is the best lower-fat substitute for heavy cream in coffee?

This particular recipe is not ideal for coffee because cornstarch can give a drink a slightly thick or starchy texture. For coffee, use milk on its own if a lighter, thinner result is acceptable, or select a coffee creamer formulated to pour smoothly into hot drinks. The right option depends on whether you value a creamy texture, a neutral flavor, or simply a lighter addition.
