Ingredients for Slow Cooker Loaded Potato Soup

For the Soup Base:

• 2 lbs (about 4-5 medium) Russet or Yukon Gold potatoes, peeled and diced into 1-inch (2.5 cm) cubes
• 1 medium yellow onion, chopped
• 2 cloves garlic, minced
• 6 cups (1.4 L) chicken broth or vegetable broth
• 1 teaspoon salt, or to taste
• ½ teaspoon black pepper, or to taste
• 4-6 slices bacon, cooked crisp and crumbled (reserve 2 tablespoons bacon grease)

For Thickening & Creaminess:

• 2 tablespoons (30 g) unsalted butter
• 2 tablespoons (15 g) all-purpose flour
• 1 cup (240 ml) heavy cream or half-and-half
• 1 ½ cups (170 g) shredded sharp cheddar cheese, plus more for garnish

For Garnish:

• ½ cup (30 g) chopped green onions or chives
• Extra crumbled bacon
• Extra shredded cheddar cheese

Ingredient Notes

• Potatoes: Russet potatoes break down nicely, contributing to a creamy texture. Yukon Golds also work well and offer a slightly waxier texture if you prefer some potato chunk integrity. Avoid waxy red or new potatoes as they don’t break down as easily.
• Broth: Chicken broth adds a rich flavor, but vegetable broth can be used for a vegetarian option (omit bacon as well). Choose low-sodium broth to control the overall saltiness.
• Bacon: Choose thick-cut bacon for the best flavor and texture in your soup. Reserve a little bacon grease to sauté the onion and garlic for an extra layer of savory depth.
• Cheese: Freshly shredded cheddar cheese melts much smoother and tastes better than pre-shredded varieties, which often contain anti-caking agents.
• Thickening: The butter and flour create a roux that helps thicken the soup to a perfect consistency. Cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) can be used as an alternative if you prefer to avoid flour.

Equipment You’ll Need

• 6-quart or larger slow cooker
• Large skillet
• Whisk
• Potato masher or immersion blender (optional, for desired creaminess)
• Cutting board and knife

How to Make Cozy Slow Cooker Loaded Potato Soup

1. Cook the Bacon: In a large skillet over medium heat, cook the bacon until crisp. Remove bacon from skillet, drain on paper towels, and crumble once cooled. Reserve about 2 tablespoons of bacon grease in the skillet.
2. Sauté Aromatics (Optional but Recommended): Add the chopped onion to the reserved bacon grease in the skillet and cook until softened, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant. This step enhances flavor significantly.
3. Combine in Slow Cooker: Add the diced potatoes, sautéed onion and garlic (if using), chicken broth, salt, and pepper to your slow cooker. Stir gently to combine.
4. Slow Cook: Cover and cook on LOW for 4-6 hours or on HIGH for 2-3 hours, or until the potatoes are very tender and easily mashable.
5. Prepare Thickener: While the soup is cooking, melt the 2 tablespoons of butter in a small saucepan over medium heat. Whisk in the 2 tablespoons of flour and cook for 1-2 minutes, stirring constantly, to create a roux. This will form a thick paste.
6. Thicken the Soup: Once the potatoes are tender, remove the lid. Add the roux to the slow cooker, stirring vigorously to prevent lumps and incorporate it completely. Cook for another 15-20 minutes on HIGH, or until the soup has visibly thickened.
7. Add Cream and Cheese: Stir in the heavy cream and 1 ½ cups of shredded cheddar cheese until the cheese is melted and fully incorporated. If desired, use a potato masher or an immersion blender to gently mash some of the potatoes for a creamier consistency, leaving some chunks for texture.
8. Finish and Serve: Stir in half of the crumbled bacon. Taste and adjust seasonings as needed. Serve hot, garnished with the remaining crumbled bacon, extra shredded cheddar cheese, and fresh green onions.

Pro Tips for the Best Results

• Don’t Skip Sautéing: While optional, sautéing the onion and garlic in bacon grease before adding to the slow cooker adds a depth of flavor that can’t be achieved otherwise.
• Don’t Overfill: Ensure your slow cooker isn’t filled past the recommended maximum line (usually 2/3 to 3/4 full) to prevent overflow during cooking.
• Mash for Texture: If you like a smoother soup, mash more of the potatoes with a potato masher or use an immersion blender for a few pulses directly in the slow cooker. For a chunkier soup, mash less.
• Freshly Shredded Cheese: Always use freshly shredded cheese. Pre-shredded cheese contains starches that can make your soup grainy or prevent smooth melting.
• Season Throughout: Taste and adjust seasonings (salt, pepper) before serving, as flavors can mellow during slow cooking.
• Low and Slow is Best: While you can cook on high, cooking on low heat generally results in more tender potatoes and a more developed flavor.

Common Mistakes to Avoid

• Watery Soup: This often happens if you don’t use a thickener or don’t allow enough time for it to cook down slightly after adding the roux. Make sure your roux is cooked well and give the soup about 15-20 minutes after adding it to thicken.
• Gritty Cheese: Using pre-shredded cheese can lead to a gritty texture. Shred your own for the smoothest, creamiest result.
• Mushy Potatoes: While we want tender potatoes, cooking them for too long or cutting them too small can result in a completely mushy texture without any potato integrity. Stick to 1-inch (2.5 cm) cubes and check for tenderness at the lower end of the cooking time.
• Bland Flavor: Don’t forget to season with salt and pepper. The optional step of sautéing the aromatics in bacon grease also significantly boosts flavor.

Variations & Substitutions

• Cheesy Variations: Experiment with different cheeses like Monterey Jack, Colby, or even a smoked gouda for a different flavor profile.
• Add Veggies: Stir in some frozen corn, diced carrots, or celery along with the potatoes for added nutrients and texture. Add them at the beginning of cooking.
• Spice It Up: A pinch of cayenne pepper or a dash of hot sauce can add a nice kick to your soup.
• Smoked Paprika: Add a teaspoon of smoked paprika with the garlic for a deeper, smoky flavor.
• Protein Boost: Add cooked, shredded chicken or ham during the last hour of cooking for an even heartier meal.
• Dairy-Free Option: Use a plant-based milk (like unsweetened cashew or oat milk) and a dairy-free cream cheese or vegan shredded cheese alternative. You may need to adjust thickening.

Serving Suggestions

This Cozy Slow Cooker Loaded Potato Soup is a meal in itself, but it pairs wonderfully with a few simple sides. Serve it with a crusty loaf of bread or garlic bread for dipping, or a fresh green salad with a light vinaigrette to balance the richness. For an extra touch, offer a topping bar with extra bacon, cheese, green onions, and even a dollop of sour cream or Greek yogurt.

Storage & Reheating

• Refrigerator: Store leftover soup in an airtight container in the refrigerator for up to 3-4 days.
• Freezer: This soup freezes moderately well. The texture of the potatoes might change slightly upon thawing, becoming a bit softer. Freeze in individual portions in airtight, freezer-safe containers or bags for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
• Reheating: Reheat on the stovetop over medium-low heat, stirring frequently, until heated through. You may need to add a splash of milk or broth to thin it out if it has become too thick. Reheat smaller portions in the microwave, stirring halfway through.

FAQ About Slow Cooker Loaded Potato Soup

Can I make this soup vegetarian?

Yes, absolutely! Simply use vegetable broth instead of chicken broth and omit the bacon. You can replace the bacon with smoked paprika for a smoky flavor or a plant-based bacon substitute.

What kind of potatoes are best for potato soup?

Russet potatoes are excellent for potato soup as they break down easily, contributing to a wonderfully creamy texture. Yukon Gold potatoes are also a great choice, offering a slightly richer flavor and holding their shape a bit more.

How can I make my potato soup thicker?

This recipe uses a butter and flour roux for thickening. If you find your soup isn’t thick enough, you can create a slurry with 1-2 tablespoons of cornstarch mixed with an equal amount of cold water, then stir it into the hot soup and cook for another 15-20 minutes until thickened.

Can I prepare this soup ahead of time?

Yes, this soup is perfect for making ahead! It often tastes even better the next day as the flavors meld. Store it in the refrigerator and reheat following the instructions above.

Why did my cheese become grainy in the soup?

Grainy cheese is typically caused by using pre-shredded cheese, which contains anti-caking agents that don’t melt smoothly. Always shred your own cheese from a block for the best, creamiest results.

Can I use milk instead of heavy cream or half-and-half?

You can use whole milk, but the soup will be less rich and creamy. If using skim or low-fat milk, the soup may curdle or separate due to the lower fat content when heated, especially with cheese. For best results, stick to heavy cream or half-and-half.
