This comforting and creamy potato soup comes straight from the granddaughter of an Idaho potato farmer. It’s thick, luxurious, and perfectly hearty — no fancy ingredients or long simmer times required.
4 cups diced Russet potatoes (about 2 large or 2 lbs)
1 cup diced carrots (about 2 large)
1 clove garlic, minced
3 cups water (just enough to barely cover the vegetables)
1 tablespoon Better Than Bouillon Chicken Base (chicken or turkey flavor)
¼ cup fresh parsley, chopped (or 1 tablespoon dried)
1 teaspoon kosher salt
For the White Sauce (Béchamel)
½ cup butter (1 stick)
½ cup all-purpose flour
½ teaspoon kosher salt
½ teaspoon black pepper
4 cups whole milk
Optional Garnishes
Shredded cheddar cheese
Chopped green onions
Extra chopped parsley
Instructions
1. Cook the Vegetables
Peel and dice the potatoes into small cubes (about ½ inch). Add them to a 3-quart stockpot.
Dice the carrots to match the potato size and add them to the pot.
Add minced garlic, 3 cups of water, the bouillon base, parsley, and 1 teaspoon salt.
Bring to a boil over high heat, then reduce to medium and simmer gently for about 20 minutes, with the lid vented.
When the potatoes and carrots are tender (easily pierced with a fork), remove from heat.
Use a potato masher to achieve your preferred texture — chunky, smooth, or somewhere in between. (For a silky finish, use an immersion blender.)
2. Make the White Sauce
In a separate saucepan, melt ½ cup butter over medium heat.
Whisk in ½ cup flour, ½ teaspoon salt, and ½ teaspoon pepper to form a roux. Cook for 1–3 minutes, stirring constantly.
Gradually whisk in 4 cups milk, about 1 cup at a time, whisking until smooth before adding more. Tip: Warming the milk beforehand in the microwave for 1–2 minutes helps prevent lumps and speeds things up.
Bring the sauce to a gentle boil, stirring constantly. Let it bubble for 1 minute, then remove from heat.
3. Combine and Serve
Pour the white sauce into the pot with the mashed vegetables. Stir well until fully blended.
Serve hot, topped with shredded cheese, green onions, and a sprinkle of parsley.
Storage
Store leftovers in the refrigerator for up to 5 days.
Do not freeze. Potatoes absorb moisture and cause the sauce to separate and turn grainy.
