Homemade Cream of Soup Mix – A Pantry Staple

I remember my grandmother always having a little jar of something mysterious on her pantry shelf. As a kid, I’d sneak a peek, wondering what secret ingredient she used to make her casseroles so incredibly creamy and comforting. Only later did I discover it was her own homemade cream of soup mix, a simple blend of pantry staples that transformed into culinary gold with just a little water and heat. The aroma of those bubbling casseroles, rich with the subtle flavors of chicken, celery, and onion, still brings me right back to her cozy kitchen, a place filled with love and delicious food.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 5 minutes
• Total Time: 20 minutes
• Yields: 3 cups of mix
• Dietary Type: Adaptable to Vegetarian/Vegan

Ingredients

• 2 cups powdered milk
• ½ cup cornstarch, plus 2 tablespoons cornstarch
• ½ cup instant mashed potatoes
• ¼ cup chicken bouillon granules (see variations for vegetarian options)
• 2 teaspoons dried parsley
• 2 teaspoons dried onion flakes
• 1 teaspoon dried celery flakes
• 1 teaspoon instant minced garlic
• 1 teaspoon onion powder
• ½ teaspoon dried marjoram
• ¼ teaspoon garlic powder
• ⅛ teaspoon white pepper

Equipment Needed

• Airtight container (jar or storage container)
• Microwave-safe bowl
• Whisk
• Measuring cups and spoons

Instructions

1. In a large bowl, thoroughly combine all of the ingredients: powdered milk, cornstarch (including the extra 2 tablespoons), instant mashed potatoes, chicken bouillon granules, dried parsley, dried onion flakes, dried celery flakes, instant minced garlic, onion powder, dried marjoram, garlic powder, and white pepper. Ensure there are no clumps of powdered milk or cornstarch.
2. Transfer the mixture to an airtight container. A glass jar or a resealable plastic container works well.
3. Store the container in a cool, dry place, such as a pantry, for up to one year.
4. To use as a cream of chicken soup substitute (equal to one 10.75-ounce can of condensed soup): In a microwave-safe bowl, combine 1 ⅓ cups of water with 6 tablespoons of the dry soup mix.
5. Heat the mixture on high in the microwave for 3 to 5 minutes, or until it thickens and becomes bubbly. Whisk the mixture occasionally during heating to prevent lumps from forming and to ensure even thickening. Start with 3 minutes and add time as needed, checking frequently.
6. For cream of mushroom soup: While the soup is heating, sauté ½ to 1 cup of sliced mushrooms in a little butter or oil until tender. Add the sautéed mushrooms to the thickened soup and stir to combine.
7. For cream of celery soup: While the soup is heating, sauté one chopped rib of celery in a little butter or oil until softened. Alternatively, add ¼ teaspoon of celery salt to the soup mixture along with the water before heating.
8. Adjusting for smaller batches: If you only need half a can of condensed soup, simply halve the measurements. Use ⅔ cup water and 3 tablespoons of the dry mix. This is especially useful when making smaller portions or adjusting recipes.

Expert Tips & Tricks

• Ensure complete dryness: Moisture is the enemy of this mix. Make sure all utensils and the storage container are completely dry before combining the ingredients. This will prevent clumping and extend the shelf life.
• Bouillon adjustment: Taste the finished soup before adding any additional salt. The bouillon granules are often quite salty, and you may not need any extra.
• Vegetarian/Vegan variation: For a vegetarian or vegan version, substitute the chicken bouillon granules with vegetable bouillon granules or a powdered mushroom broth. Ensure that your instant mashed potatoes are also vegetarian/vegan-friendly.
• Microwave power variations: Microwave cooking times can vary depending on the power of your microwave. Start with a shorter cooking time and add time as needed, whisking frequently to prevent scorching.
• Whisking technique: When whisking the soup while it’s heating, use a quick, circular motion to break up any lumps and ensure a smooth, creamy texture.
• Adding herbs: Feel free to add other dried herbs to the mix according to your preferences. Thyme, basil, or oregano would all be delicious additions.
• Flavor enhancement: For a richer flavor, use milk or broth instead of water when preparing the soup.

Serving & Storage Suggestions

Serve your homemade cream of soup immediately after preparing it. It’s a versatile base for casseroles, sauces, and soups.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm on the stovetop over low heat, stirring occasionally, or in the microwave, checking frequently and stirring in between intervals. The texture may change slightly upon reheating, but the flavor will remain. It is not recommended to freeze the prepared soup, as the texture can become grainy after thawing.

The dry soup mix itself should be stored in an airtight container in a cool, dry place for up to a year.

FAQs (Frequently Asked Questions)

Q: Can I use fresh herbs instead of dried herbs?
A: While you can use fresh herbs, dried herbs are recommended for the mix because they have a longer shelf life and won’t introduce moisture to the mix. If using fresh, add them when preparing the soup.

Q: My soup is lumpy. How can I fix it?
A: If your soup becomes lumpy, use an immersion blender to smooth it out, or whisk vigorously. Ensure you’re whisking frequently during the heating process to prevent lumps from forming in the first place.

Q: How can I make this mix lower in sodium?
A: Use a low-sodium or no-sodium chicken bouillon, and avoid adding any extra salt to the finished soup.

Q: Can I use this mix as a gravy base?
A: Yes, you can use this mix as a gravy base. Simply adjust the amount of liquid to achieve the desired consistency. Start with less liquid and add more until you reach your preferred thickness.

Q: How long will the prepared soup last in the refrigerator?
A: The prepared soup will last for up to 3 days in the refrigerator. Make sure to store it in an airtight container.
