Here's what you need to make this creamy potato bacon soup.
See Recipe Card Below This Post For Ingredient Quantities
- Bacon, diced: The smoky, salty base of the soup. Cook it until crispy, then use the rendered fat to build flavor in the soup.
- Unsalted butter: Adds richness and helps sauté the vegetables. Combined with bacon fat, it creates a flavorful base.
- Onion, diced: Part of the Cajun Potato Soup holy trinity. Adds sweetness and depth to the soup.
- Green bell pepper, diced: Another part of the holy trinity. Brings a mild, slightly sweet flavor.
- Celery, diced: Completes the holy trinity. Adds a subtle earthiness and texture.
- Garlic, minced: Adds aromatic, savory flavor that deepens as it cooks.
- All-purpose flour: Thickens the soup and gives it a creamy, velvety texture.
- Cajun seasoning: The star spice blend. Adjust the amount based on your heat preference.
- Kosher salt: Enhances all the flavors. Taste and adjust as you go.
- Russet potatoes, peeled and cut into 1-inch cubes: The base of the soup. Russets break down slightly as they cook, helping to thicken the broth.
- Chicken stock: Provides the savory liquid base. Use vegetable stock for a vegetarian version.
- Whole milk: Adds creaminess without being too heavy.
- Heavy cream (optional): Makes the soup extra rich and velvety. You can substitute with more chicken stock for a lighter soup.
- Green onions, sliced (for garnish): Adds a fresh, bright finish.
How to Make Cajun Potato Soup
This hearty Cajun Potato Soup with bacon comes together in a few simple steps.
Cook the bacon: In a large Dutch oven, cook the diced bacon over medium heat until crispy, about 6 to 8 minutes. Remove the bacon with a slotted spoon and drain it on paper towels. Leave about 2 tablespoons of bacon fat in the pot for flavor.
Sauté the vegetables: Add the butter to the pot with the bacon fat. Stir in the diced onion, bell pepper, and celery, and cook until softened, about 5 minutes. The vegetables should be tender and fragrant. Add the minced garlic and cook for 1 more minute, stirring constantly so it doesn't burn.
Add flour and spices: Sprinkle the flour over the vegetables and stir to coat everything evenly. Add the Cajun Potato Soup seasoning and salt, then cook for 2 minutes, stirring frequently. This step cooks out the raw flour taste and toasts the spices.
Simmer the potatoes: Add the cubed potatoes to the pot and gradually pour in the chicken stock while stirring. Bring the mixture to a simmer and cook for 12 to 15 minutes, or until the potatoes are tender and easily pierced with a fork. Taste the broth and adjust the seasoning as needed.
Add the dairy: Stir in the milk and heavy cream if using. Simmer gently for 5 minutes, but don't let the soup boil, or the dairy may curdle.
Optional blending: For a creamier soup, use an immersion blender to puree part of the soup, leaving some potato chunks for texture. This step is optional but makes the soup extra thick and velvety.
Finish with bacon: Return the cooked bacon to the pot, stir to combine, and simmer for 2 minutes to heat everything through.
Serve: Ladle the soup into bowls, garnish with sliced green onions, and serve hot with cornbread or crusty bread on the side.
Substitutions and Variations
Make it vegetarian. Skip the bacon and use vegetable stock instead of chicken stock. Add smoked paprika for a smoky flavor.
Use different potatoes. Yukon Gold potatoes work well and create a creamier texture. Avoid waxy potatoes like red potatoes, as they don't break down as easily.
Skip the cream. For a lighter soup, use extra chicken stock instead of heavy cream. The soup will still be creamy from the flour and milk.
Add more vegetables. Toss in corn, diced carrots, or chopped kale for extra nutrition and texture.
Make it spicier. Add a pinch of cayenne pepper, diced jalapeños, or hot sauce for extra heat.
Equipment for Cajun Potato Soup
- Large Dutch oven or soup pot: Holds all the ingredients and distributes heat evenly.
- Slotted spoon: For removing the crispy bacon without losing the fat.
- Knife and cutting board: For chopping vegetables and potatoes.
- Immersion blender (optional): Purees part of the soup for a creamier texture.
- Spoon or ladle: For stirring and serving.
Storage and Reheating Tips
Store leftovers in an airtight container in the fridge for up to 4 days. The soup may thicken as it sits, so add a splash of stock or milk when reheating.
Reheat on the stove. Warm the soup over medium-low heat, stirring occasionally, until heated through. Add a little liquid if it's too thick.
Reheat in the microwave. Heat individual portions in the microwave for 2 to 3 minutes, stirring halfway through.
Freeze for later. The soup freezes well for up to 3 months. Thaw in the fridge overnight and reheat on the stove. The texture may change slightly, but the flavor stays great.
Serving Suggestions
Serve with cornbread. Warm, buttery cornbread is the perfect pairing for this comforting Cajun Potato Soup.
Add crusty bread. Serve with a thick slice of sourdough or French bread for dipping.
Top with extra bacon. Crumble extra crispy bacon on top for added texture and smokiness.
Pair with a simple salad. Balance the richness of the soup with a light green salad or my Mango Slaw for a fresh contrast.
Top Tip
Don't skip the bacon fat. The rendered bacon fat adds smoky, savory flavor that you can't replicate with just butter or oil.
Cook the flour long enough. Two minutes of cooking the flour with the vegetables and spices removes the raw taste and creates a smooth, thick base.
Adjust the seasoning gradually. Cajun Potato Soup seasoning blends vary in heat and saltiness. Start with less and add more to taste.
Simmer gently after adding dairy. Boiling the soup after adding milk and cream can cause it to curdle. Keep the heat low and stir occasionally.
Blend for extra creaminess. Using an immersion blender on part of the soup creates a thick, velvety texture while leaving some chunks for interest.
FAQ
What are some common mistakes to avoid when making potato soup?
Avoid boiling the soup after adding the dairy, as this can cause it to curdle. Cut the potatoes into even pieces so they cook uniformly, and don't skip the roux step, which is what thickens the soup and gives it body.
What can I add to Cajun Potato Soup to give it more flavor?
Add crispy bacon, Cajun Potato Soup seasoning, fresh garlic, sautéed onions, celery, and bell peppers. A splash of hot sauce, a squeeze of lemon juice, or a dollop of sour cream can also brighten the flavor. Fresh herbs like thyme or parsley add freshness.
Why is it called crack potato soup?
"Crack" potato soup is a nickname for loaded baked potato soup that's so rich, creamy, and addictive that people can't stop eating it. It's usually loaded with bacon, cheese, sour cream, and green onions, making it incredibly indulgent and hard to resist.
What soup is famous in Louisiana?
Louisiana is famous for gumbo, a thick stew made with a dark roux, the holy trinity (onion, bell pepper, celery), and protein like shrimp, sausage, or chicken. Other famous Louisiana soups include red beans and rice, turtle soup, and crawfish bisque.
