Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 1 hour
• Total Time: 1 hour 30 minutes
• Servings: 50
• Yield: Approx. 4 gallons
• Dietary Type: Vegetarian (Can be made vegan with substitutions)

Ingredients

• 5 lbs potatoes
• 3 quarts water
• 2 tablespoons salt
• 1 tablespoon MSG (optional)
• 3 lbs onions
• 1 cup butter or 1 cup margarine
• 1/2 cup all-purpose flour
• 4 quarts milk
• 2 cups cream
• White pepper, to taste
• 1 cup chopped chives or 1 cup chopped scallion tops, for garnish

Equipment Needed

• Large stockpot (at least 5-gallon capacity)
• Heavy-bottomed saucepan
• Large stirring spoons
• Whisk
• Potato masher or immersion blender (optional)
• Cutting board
• Chef’s knife

Instructions

1. Begin by prepping the potatoes. Peel all 5 pounds and cut them into small, uniform dice. This will ensure even cooking.
2. Place the diced potatoes in the large stockpot and cover with 3 quarts of water.
3. Add 2 tablespoons of salt and, if desired, 1 tablespoon of MSG. The MSG will enhance the savory flavor, but it’s perfectly fine to omit it.
4. Cover the pot and cook over medium-high heat until the potatoes are very soft and easily mashed, about 20-25 minutes. They should be practically falling apart.
5. Once the potatoes are cooked, use a whisk or an immersion blender to puree the mixture until it’s smooth. You can also use a potato masher if you prefer a slightly chunkier texture. Set aside.
6. While the potatoes are cooking, prepare the onions. Chop the 3 pounds of onions into a small dice. Consistency is key here to ensure they cook evenly.
7. In the heavy-bottomed saucepan, melt 1 cup (1/2 pound) of butter or margarine over medium heat. Make sure your pan is large enough to accommodate all the onions without overcrowding.
8. Add the chopped onions to the melted butter and cook, stirring frequently, until they are soft and golden, about 15-20 minutes. Be careful not to let them brown or burn, as this will impart a bitter flavor to the soup. You want them tender and slightly sweet.
9. Sprinkle 1/2 cup of all-purpose flour over the cooked onions. Cook, stirring constantly, for 2-3 minutes to create a roux. This will help thicken the soup. Be sure to cook out the raw flour taste by stirring continuously, but avoid browning the roux.
10. Gradually add 4 quarts of milk to the onion mixture, whisking continuously to prevent lumps from forming. This step requires patience! Add the milk in a slow, steady stream, ensuring each addition is fully incorporated before adding more.
11. Cook, stirring frequently, until the sauce is smooth and thickened, about 10-15 minutes. The sauce should be thick enough to coat the back of a spoon.
12. Simmer the sauce for 10 minutes, stirring often, to fully develop the flavors. This low, slow simmering is important for a rich, well-rounded taste.
13. Combine the thickened onion sauce with the pureed potato mixture in the large stockpot. Heat well over medium heat, stirring frequently to prevent sticking.
14. Add 2 cups of cream and heat gently. Do not boil after adding the cream, as it may curdle. If you prefer a lighter soup, you can substitute the cream with more milk or undiluted evaporated milk.
15. Taste and adjust the seasoning with more salt and a pinch of white pepper. Remember that flavors will meld and deepen as the soup sits, so err on the side of slightly under-seasoning initially.
16. Finely chop fresh chives or scallion greens to make about 1 cup.
17. Serve the soup hot with a ladle, about 3/4 cup to a portion.
18. Sprinkle each serving with about 1/2 teaspoon of chopped chives or scallion greens for a fresh, vibrant garnish.

Expert Tips & Tricks

• Make-Ahead Magic: The potato soup base (before adding the cream) can be made a day or two ahead and stored in the refrigerator. This is a huge time-saver when cooking for a large crowd. Just reheat gently before adding the cream and serving.
• Enhance the Flavor: For a smoky depth, consider adding a few slices of cooked and crumbled bacon to each serving.
• Thickness Adjustment: If the soup is too thick, add more milk or water to reach your desired consistency. If it’s too thin, simmer uncovered for a longer period to allow some of the liquid to evaporate.
• Vegan Variation: Substitute the butter with a plant-based butter alternative, use your favorite plant-based milk instead of dairy milk, and omit the cream or replace it with a vegan cream alternative.
• Equipment is Key: Using a large, heavy-bottomed pot is essential to prevent scorching, especially when making large batches.

Serving & Storage Suggestions

Serve the potato soup hot in bowls or mugs, garnished with fresh chives or scallions. Crusty bread or a simple side salad makes a perfect accompaniment.

Storage:

• Room Temperature: Do not leave at room temperature for more than 2 hours.
• Refrigerator: Store leftover soup in an airtight container in the refrigerator for up to 3-4 days.
• Freezer: For longer storage, freeze the soup in freezer-safe containers for up to 2-3 months. Thaw completely in the refrigerator before reheating.

Reheating:

Reheat the soup gently over medium heat on the stovetop, stirring frequently. Add a splash of milk or broth if needed to thin it out. Avoid boiling, especially if the soup contains cream. You can also reheat individual portions in the microwave, stirring occasionally.

FAQs (Frequently Asked Questions)

Q: Can I make this soup in a slow cooker?
A: Yes, you can. Sauté the onions first, then combine all ingredients (except the cream and chives) in the slow cooker. Cook on low for 6-8 hours or on high for 3-4 hours. Stir in the cream just before serving.

Q: How do I prevent the soup from curdling when adding the cream?
A: Make sure the soup is not boiling when you add the cream. Heat it gently and stir frequently to prevent curdling. Using room temperature cream can also help.

Q: Can I use different types of potatoes?
A: Yes, Yukon Gold potatoes work well for their creamy texture. Russet potatoes are also suitable, but they may require more pureeing to achieve a smooth consistency.

Q: What can I use if I don’t have chives or scallions?
A: Fresh parsley or dill can be used as a substitute for garnish, although the flavor profile will be slightly different.

Q: How long will the soup last in the freezer?
