Yep. Someone on here shared it with me. I will share with you.
Homemade Cream of ___ Soup Mix
2 cups powdered milk
¾-1 ¼ cups cornstarch or 2 ½ cups flour
¼ cups chicken, beef, or vegetable bouillon granules
2 Tablespoons dried onion flakes or 1 teaspoon of onion powder
1 teaspoon dried thyme, crushed
1 teaspoon dried basil or marjoram, crushed
½ teaspoon black or white pepper
Combine all ingredients and blend until mixed. Store in an airtight container in a cool dry place for up to 1 year. This recipe makes 3 cups and is enough for 9 cans of soup.
To substitute for one can of condensed cream soup:
In a 1-quart saucepan or microwave safe bowl, combine 1/3 cup of soup mix and 1 1/4 cup water. (If made with flour, add ½ cup mix to 1 ¼ water.) For soup, double the water. Bring to a boil or microwave on high for 2 to 2 1/2 minutes, stirring occasionally.
