Prep Work

1. Peel and dice the potatoes into uniform 1-inch pieces; place them directly into your slow cooker. (Look for: The potatoes will be roughly the same size, ensuring even cooking, and will begin to fill the slow cooker.)
2. Chop the yellow onion and mince the garlic. (Look for: Aromatic scents of fresh onion and garlic will fill the air as you prepare them.)
3. Cook the bacon in a skillet over medium heat until it is perfectly crisp. Remove the bacon to a plate lined with paper towels to drain. Once cool, crumble it and set aside for garnish. (Look for: The bacon will turn golden brown and make a satisfying sizzling sound as it cooks, rendering flavorful drippings.)

Building the Base

1. Drain most of the bacon drippings from the skillet, leaving about 1 tablespoon. Add the butter to the skillet and melt it over medium heat. Add the chopped onion and sauté for 5-7 minutes until softened and translucent. (Look for: The onions will become tender and fragrant, softening beautifully in the butter and bacon drippings.)
2. Stir in the minced garlic and cook for another minute until it becomes fragrant. (Look for: A rich, pungent garlic aroma will emerge, intensifying the savory smell.)
3. Sprinkle in the all-purpose flour and cook for one minute, stirring constantly, to create a light roux. (Look for: The flour will coat the aromatics and smell slightly nutty and toasty as it cooks, thickening the mixture.)

Slow Cooking

1. Transfer the sautéed aromatics from the skillet to the slow cooker with the diced potatoes. Pour in the chicken or vegetable broth, then add the salt and black pepper. (Look for: The liquid will largely cover the potatoes and aromatics, settling into the slow cooker for a long, slow simmer.)
2. Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, until the potatoes are completely fork-tender. (Look for: The potatoes will yield easily when pierced with a fork, and the kitchen will fill with a savory, comforting aroma as the soup cooks.)

Finishing Touches

1. Once the potatoes are tender, use a potato masher or a large spoon to gently mash some of the potatoes directly in the slow cooker. Mash to your desired consistency; some prefer a chunky soup, others a very creamy texture. (Look for: The soup will visibly thicken as you mash, creating a heartier body and texture.)
2. Stir in the whole milk and 1 cup of the shredded cheddar cheese until the cheese is completely melted and the soup is smooth and creamy. (Look for: The soup will become visibly richer and silkier, with the cheese melting seamlessly into the broth.)
3. Taste the soup and adjust the seasoning if needed, adding more salt or pepper to your preference. (Look for: The flavors will be well-balanced and rich, reaching their peak savory goodness.)
4. Ladle the hot soup into bowls and garnish generously with the remaining 1 cup shredded cheddar cheese, crumbled bacon, and fresh green onions or chives. (Look for: The soup will be steaming hot, and the garnishes will add vibrant color and enticing textures to each serving.)

Make-Ahead Tips

Preparing this delicious soup in advance is a breeze! You can chop your potatoes, onions, and garlic the night before and store them in separate, sealed containers in the refrigerator. Cook your bacon in advance and crumble it, keeping it refrigerated until ready to serve. This little bit of foresight means you will have even less hands-on time when you are ready to start the slow cooker.

Freezing Instructions

To freeze this Crockpot Potato Soup, first allow it to cool completely to room temperature. Transfer the cooled soup to freezer-safe containers or heavy-duty freezer bags, leaving about an inch of headspace for expansion. It can be stored in the freezer for up to 3 months. When you are ready to enjoy it, thaw the soup overnight in the refrigerator. Reheat gently on the stovetop over low heat, stirring frequently, or in the microwave until heated through. You may want to add a splash of fresh milk or cream and a sprinkle of cheese when reheating to restore its original creamy texture and flavor.

Substitutions

Feel free to swap Russet potatoes for Yukon Gold for a slightly waxier texture, or even add some sweet potato for a hint of sweetness and extra nutrients. For a vegetarian version, simply use vegetable broth instead of chicken broth and omit the bacon; you can add smoked paprika for a smoky depth. Half-and-half or evaporated milk can replace whole milk for an even richer soup, or use a dairy-free milk alternative like cashew or oat milk for a lactose-free option. If you do not have flour, a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) can be stirred in during the last 30 minutes of cooking for thickening. Any mild or sharp shredded cheese will work wonderfully in place of cheddar.

Frequently Asked Questions

What kind of potatoes are best for potato soup?

Russet potatoes are excellent for potato soup because their high starch content breaks down easily, creating a wonderfully creamy texture when mashed. Yukon Gold potatoes are another great choice; they offer a slightly buttery flavor and maintain a bit more shape while still being creamy.

Can I make this potato soup vegetarian?

Absolutely! To make this soup vegetarian, simply swap the chicken broth for vegetable broth. You will also need to omit the bacon or use a plant-based bacon alternative. For a smoky flavor without the bacon, try adding a half teaspoon of smoked paprika with the other seasonings.

How can I make my potato soup thicker?

There are a few ways to thicken your potato soup. You can mash more of the cooked potatoes directly in the slow cooker to release more starch. If you need more thickening, you can create a cornstarch slurry by mixing 1 tablespoon of cornstarch with 2 tablespoons of cold water, then stir it into the soup during the last 30 minutes of cooking. Another option is to use a bit more flour in the initial roux.

Can I cook this potato soup on a high setting?

Yes, you can cook this Crockpot Potato Soup on a high setting. It will typically take about 3-4 hours on high, compared to 6-8 hours on low. Just ensure the potatoes are completely fork-tender before mashing and adding the dairy.

How long does potato soup last in the refrigerator?

Properly stored in an airtight container, this potato soup will last for 3-4 days in the refrigerator. It often tastes even better the next day as the flavors have more time to meld.

Can I add other vegetables to this potato soup?

Definitely! This soup is very versatile. You can add finely diced carrots and celery along with the onions and garlic, or stir in frozen corn or peas during the last hour of cooking for extra texture and nutrients. Just be mindful not to overcrowd the slow cooker.

Variations

Protein

• Ham and Cheese Potato Soup: Add 1 cup of diced cooked ham to the slow cooker along with the potatoes for a heartier, smoky flavor. This works wonderfully with leftover holiday ham.
• Chicken Bacon Ranch Potato Soup: Stir in 2 cups of shredded cooked chicken and 1 tablespoon of ranch seasoning mix during the last 30 minutes of cooking for a flavorful twist.

Vegetable

• Loaded Veggie Potato Soup: Add 1 cup of mixed frozen vegetables (like corn and peas) or 1/2 cup each of finely diced carrots and celery along with the potatoes for extra nutrition and color.

Seasoning

• Spicy Southwest Potato Soup: Add 1 teaspoon of chili powder, 1/2 teaspoon of cumin, and a can of diced green chiles (drained) to the slow cooker for a warming, zesty kick.
• Herb Garden Potato Soup: Incorporate fresh herbs like a sprig of rosemary or a few sprigs of thyme tied together, adding them to the slow cooker with the broth and removing before mashing for an aromatic depth.

Dietary

• Dairy-Free Potato Soup: Replace whole milk with unsweetened full-fat cashew milk or oat milk, and use a dairy-free shredded cheese alternative. Nutritional yeast can also add a cheesy flavor without dairy.
