Step-by-Step Instructions

Step 1 — Prep Your Vegetables

Dice one large yellow onion, two celery stalks, and one green bell pepper. This “holy trinity” of Cajun cooking forms the flavor base for your Fall-Inspired Hearty Cajun Potato Soup. Mince three cloves of garlic and set aside.

Tip: For a smoother soup, you can finely chop the vegetables. For a chunkier, heartier texture, a rough chop is perfect.

Step 2 — Sauté the Aromatics

In a large Dutch oven or heavy-bottomed pot, heat 2 tablespoons of olive oil or butter over medium heat. Add the diced onion, celery, and bell pepper. Sauté for 5-7 minutes, stirring occasionally, until the vegetables have softened.

Add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic.

Step 3 — Build the Flavor Base

Stir in 2 tablespoons of Cajun seasoning, 1 teaspoon of smoked paprika, and 1/4 teaspoon of cayenne pepper (adjust for heat preference) into the vegetable mixture. Cook for 1 minute to toast the spices, which will deepen their flavor.

Pour in 4 cups of chicken or vegetable broth, using a wooden spoon to scrape up any browned bits from the bottom of the pot.

Step 4 — Add Potatoes and Simmer

Add 2 pounds of peeled and cubed russet potatoes to the pot. Bring the liquid to a boil, then reduce the heat to a gentle simmer. Cover the pot and let it cook for 15-20 minutes.

The potatoes are done when they are fork-tender and easily break apart when pressed against the side of the pot.

Step 5 — Create a Creamy Base

In a separate saucepan, melt 4 tablespoons of butter over medium heat. Whisk in 1/4 cup of all-purpose flour and cook for 1-2 minutes to form a roux. Slowly whisk in 2 cups of whole milk or half-and-half until the mixture is smooth and slightly thickened.

Tip: Temper the milk mixture by slowly adding a ladle of the hot soup broth to it before combining everything to prevent curdling.

Step 6 — Combine and Final Simmer

Pour the creamy milk mixture into the large pot with the potatoes and broth. Stir to combine thoroughly. Add 1 cup of shredded sharp cheddar cheese and stir until melted and incorporated.

Let the Fall-Inspired Hearty Cajun Potato Soup simmer uncovered for another 5-10 minutes, allowing it to thicken to your desired consistency. Season with salt and black pepper to taste.

Step 7 — Serve and Garnish

Ladle the hot soup into bowls. Top with your favorite garnishes like crispy chopped bacon, sliced green onions, extra shredded cheese, or a dollop of sour cream.

This soup is best served immediately while hot, making it the ultimate comfort food for a crisp fall day.

Healthier Alternatives

Common Mistakes to Avoid

• Mistake: Using waxy potatoes that don’t break down. Fix: Opt for starchy Russets or Yukon Golds to create a naturally creamy base.
• Mistake: Adding Cajun seasoning too early. Fix: Bloom spices in oil for 30 seconds at the end to unlock their full, vibrant flavor.
• Mistake: Overcrowding the pot with vegetables. Fix: Sauté onions and celery in batches to ensure they caramelize, not steam.
• Mistake: Using a weak, store-bought broth. Fix: Simmer a ham hock or use a high-quality stock for a richer, deeper flavor foundation.
• Mistake: Boiling the soup aggressively after adding dairy. Fix: Stir in cream or milk off the heat to prevent curdling and splitting.
• Mistake: Undersalting during cooking. Fix: Season in layers, tasting after each addition, as potatoes absorb a surprising amount of salt.
• Mistake: Skipping the garnish. Fix: Top with crispy bacon, green onions, and a dash of hot sauce for essential texture and heat.

Storing Tips

• Fridge: Cool your Fall-Inspired Hearty Cajun Potato Soup completely before transferring to an airtight container. It will keep well for up to 4 days.
• Freezer: This soup freezes beautifully for up to 3 months. Use a freezer-safe container, leaving about an inch of headspace for expansion.
• Reheat: Thaw frozen soup overnight in the refrigerator. Reheat gently on the stovetop or in the microwave, stirring occasionally, until it reaches an internal temperature of 165°F for food safety.

For best texture, give the soup a good stir after reheating, as the potatoes may have absorbed some liquid during storage.
