Ingredients

For the Vegetables

  • 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

  1. Peel and dice the potatoes into small cubes (about ½ inch). Add them to a 3-quart stockpot.
  2. Dice the carrots to match the potato size and add them to the pot.
  3. Add minced garlic, 3 cups of water, the bouillon base, parsley, and 1 teaspoon salt.
  4. Bring to a boil over high heat, then reduce to medium and simmer gently for about 20 minutes, with the lid vented.
  5. When the potatoes and carrots are tender (easily pierced with a fork), remove from heat.
  6. 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

  1. In a separate saucepan, melt ½ cup butter over medium heat.
  2. Whisk in ½ cup flour, ½ teaspoon salt, and ½ teaspoon pepper to form a roux. Cook for 1–3 minutes, stirring constantly.
  3. 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.
  4. 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.
