Homemade Cream Soup Substitute

This is the smart pantry hack that frees you from depending on canned cream-of-mushroom or cream-of-chicken soup for every casserole recipe. A dry mix of powdered milk, cornstarch, bouillon and dried herbs sits in a jar in your pantry, and when a recipe calls for a can of condensed soup, you just measure out ⅓ cup of mix, whisk with 1 ½ cups water, and simmer until thickened. Done.

The cornstarch is doing all the structural work. The starch absorbs water as it heats and creates the velvety, condensed-soup thickness that defines the original. No flour needed; no roux step required. Whisk into cold water first, then heat gradually for a lump-free result.

Using low-sodium bouillon is the smart choice for this homemade version. Canned condensed soups are notorious for their high sodium content. This DIY version uses less salt and lets you add more to taste at the end if needed, giving you control over the final dish.

The convenience is real. Make a single batch and you have the equivalent of 8 to 10 cans of soup in a single jar. Use it for tuna casserole, green bean casserole, scalloped potatoes, or any recipe that calls for cream-of-something soup as a binder.

Pro Tips

• Use instant non-fat dry milk powder, not the cooking-grade powdered milk. Instant dissolves smoothly.
• Store in an airtight jar at room temperature for up to 6 months.
• Whisk thoroughly in cold water before heating to prevent lumps.
• Add mushrooms, sauteed onions, celery, or chopped cooked chicken to create specific variations (cream of mushroom, celery, chicken).

Variations

• Beef bouillon instead of chicken creates a cream-of-beef equivalent.
• Add ¼ teaspoon of garlic powder to the mix for additional savory depth.
• Stir in ¼ cup of grated parmesan when reconstituting for cream-of-parmesan soup.
• Use as the base for chicken and dumpling-style stews.
