Pressure Canning Potato Soup Recipe
Making potato soup for pressure canning is incredibly straightforward, but it does require some attention to detail to ensure everything is safe, tasty, and perfectly preserved. Here’s a recipe that will guide you step-by-step through the process, starting with the basics.
Ingredients Needed
To make this creamy, hearty potato soup, here’s what you’ll need:
- 6-8 medium potatoes – peeled and diced (any waxy variety like Yukon Golds work well)
- 1 medium onion – diced
- 2-3 celery stalks – diced
- 3 cloves garlic – minced
- 4 cups chicken broth – or vegetable broth if you prefer a vegetarian option
- 2 cups whole milk – this can be substituted with half-and-half for extra creaminess
- 1 cup heavy cream – for richness
- 2 tablespoons butter – adds flavor and richness to the soup
- 1 teaspoon dried thyme – or fresh if you have it
- 1 teaspoon salt – adjust to taste
- 1/2 teaspoon black pepper – freshly ground if possible
- 1/2 teaspoon paprika – optional, for a smoky depth
- 1/2 cup shredded cheddar cheese – optional, for garnish or stirring in just before serving
- 1 tablespoon flour – for thickening the soup (optional, but it helps give a velvety texture)
- Bacon crumbles – optional for garnish
Cooking Instructions
Now that you have your ingredients ready, let’s break down the process into easy-to-follow steps:
-
Prepare Your Vegetables
Start by washing, peeling, and dicing your potatoes into small cubes (around 1/2 to 1-inch in size). Dice the onions, celery, and garlic too. If you’re adding any bacon, chop it up into small pieces.
-
Sauté Aromatics And Vegetables
In a large pot or Dutch oven, melt the butter over medium heat. Add the diced onions, celery, and garlic, and sauté them for about 3-5 minutes until the onions are translucent and the garlic is fragrant.
-
Cook The Potatoes
Add the diced potatoes to the pot along with the dried thyme, salt, pepper, and paprika. Stir everything together so that the potatoes are well coated in the butter and spices. Cook for about 5 minutes, just to start softening them.
-
Add Liquids
Pour in the chicken broth, ensuring the potatoes are covered. If necessary, add a bit more broth or water. Bring it to a boil, then reduce the heat and simmer the soup until the potatoes are tender (about 10-15 minutes). You can test them by piercing a potato cube with a fork.
-
Blend The Soup
Once the potatoes are soft, use an immersion blender to blend the soup until it reaches your desired consistency. You can leave it slightly chunky for texture or go completely smooth. If you don’t have an immersion blender, carefully transfer portions of the soup into a regular blender. Just make sure to leave the lid slightly ajar to prevent any hot splashes!
-
Finish With Dairy
Stir in the milk, heavy cream, and flour (if you want it thicker). Let the soup simmer for another 5-10 minutes. Taste for seasoning and adjust salt, pepper, or thyme as needed.
-
Can The Soup
Once your soup is complete, it’s time to can. Fill your hot, sterilized jars with the hot soup, leaving about 1-inch headspace at the top. Wipe the rims clean, and seal the jars tightly. Process in a pressure canner at 10 pounds of pressure for 30 minutes (adjust for altitude if necessary).
-
Cool And Store
After the processing time is done, allow the jars to cool completely before storing them in a cool, dark place. The soup will keep for up to a year if canned properly.
Ingredient Insights
Understanding the role each ingredient plays in the soup helps elevate the dish, and it’s crucial when canning.
- Potatoes: The star of the soup. They absorb all the flavors from the broth, butter, and seasonings, creating a satisfying, creamy texture. Starchy potatoes like Russets break down more, making the soup creamy, while waxy varieties (like Yukon Gold) maintain some shape, adding heartiness.
- Broth: Chicken broth adds a savory depth, but you can easily use vegetable broth for a lighter, vegetarian alternative. The broth acts as the base for the soup, enriching it with flavor.
- Dairy: Milk and cream bring a velvety richness, making the soup smooth and indulgent. Whole milk offers a good balance of creaminess without being too heavy, while heavy cream ups the decadence.
- Thyme & Garlic: Fresh, aromatic herbs like thyme lend a subtle earthiness, while garlic adds depth and warmth to the overall flavor profile.
Expert Tips
- Texture Control: If you prefer a chunky soup, don’t blend all the potatoes. Leave some whole or mash them lightly for that rustic texture.
- Thickening: If you like your soup on the thicker side, add the optional flour or cornstarch slurry. You can also thicken it by simmering the soup longer to reduce it.
- Safety First: When pressure canning, always follow the manufacturer’s instructions for your canner. The USDA recommends using a pressure canner for soups with low-acid ingredients like potatoes.
- Freezer Option: If you’re not ready to can, potato soup can be frozen. Let the soup cool completely, transfer it to freezer-safe containers, and freeze for up to 3 months.
Recipe Variations
The beauty of potato soup is how customizable it is! Here are some fun variations you can try:
- Cheesy Potato Soup: Stir in shredded cheddar cheese (or any other cheese you love) towards the end of cooking. It’ll melt into the soup, making it even more indulgent.
- Loaded Potato Soup: For a ’loaded’ version, add crispy bacon, sour cream, chopped green onions, and extra shredded cheese as toppings. This makes a meal that’s even heartier!
- Vegetable Potato Soup: Add extra vegetables like carrots, peas, or corn for a more colorful, nutritious soup. Just dice them small so they cook quickly and integrate well with the potatoes.
- Spicy Potato Soup: Add a pinch of cayenne pepper or diced jalapeños for some heat. It pairs wonderfully with the creamy texture of the soup.
Final Words
Canning potato soup is not only a practical way to preserve a homemade meal for the long term, but it also allows you to create a cozy dish that you can enjoy even on the busiest of days. The flexibility of this recipe means you can adjust it to your preferences and experiment with new flavors or textures.
FAQs
What Is Pressure Canning, And Why Is It Necessary For Potato Soup?
Pressure canning is a method used to safely preserve low-acid foods like potato soup by heating them to a temperature that destroys harmful bacteria, molds, and yeasts. Since potato soup contains vegetables, meats, and dairy, it must be pressure canned to ensure that the food reaches a high enough temperature to eliminate the risk of botulism, which cannot be killed at standard boiling temperatures.
Can I Use Any Type Of Potatoes For Canning Potato Soup?
While you can technically use any variety of potatoes, waxy potatoes like Yukon Golds or red potatoes work best for canning because they hold their shape and texture well after being pressure canned. Starchy potatoes, such as Russets, can turn mushy during the canning process.
Can I Add Dairy Products Like Milk Or Cream When Pressure Canning Potato Soup?
Dairy products like milk, cream, or cheese should not be added directly to potato soup for pressure canning, as they may cause spoilage or affect the safety of the canning process. Instead, you can leave out the dairy and add it when you reheat the soup after opening the jar.
What Ingredients Should I Avoid When Canning Potato Soup?
Avoid using thickening agents like flour or cornstarch in your potato soup before canning, as they can cause the soup to become too thick and unevenly processed. Additionally, avoid using dairy products or adding certain herbs and spices that can alter the preservation process.
How Long Does It Take To Pressure Can Potato Soup?
The pressure canning process for potato soup generally takes about 75-90 minutes, depending on your altitude and the type of jar you’re using. Always follow the recommendations of your pressure canner’s manual for specific times based on your location.
Can I Use A Water Bath Canner Instead Of A Pressure Canner For Potato Soup?
No, water bath canning is not suitable for potato soup, as it does not reach high enough temperatures to safely preserve low-acid foods. Only a pressure canner can reach the necessary temperature to safely process potato soup and other similar foods.
What Is The Proper Canning Jar Size For Potato Soup?
Quart jars are typically recommended for potato soup, as they allow for larger servings. However, pint-sized jars can also be used depending on your preference. Make sure the jars are sterilized before filling them with soup.
How Should I Prepare The Potatoes Before Canning Them?
Peel and chop the potatoes into uniform chunks or cubes. It’s recommended to blanch the potatoes by briefly boiling them for 2-3 minutes before canning to preserve their texture, color, and nutrients.
What Should I Do If My Pressure Canner Is Not Reaching The Required Pressure?
If your pressure canner is not reaching the correct pressure, check the sealing ring, the pressure regulator, and the heat source. Make sure the canner is clean and the valve is functioning properly. If you’re still having trouble, consider consulting the manual for troubleshooting tips.
How Long Can Pressure-canned Potato Soup Be Stored?
Properly pressure-canned potato soup can be safely stored for up to one year in a cool, dark place. After this time, the quality may begin to degrade, and the soup should be checked for signs of spoilage before consumption.
