Equipment

  • 1 large pot
  • 1 colander
  • 1 potato masher or hand mixer
  • 1 Small skillet
  • Measuring cups and spoons

Ingredients
  

  • 2 lbs 4 medium sweet potatoes, peeled and cubed
  • 1 tbsp butter
  • 3 cloves garlic crushed
  • ½ cup 1% milk
  • 2 tbsp light sour cream
  • Salt to taste
  • Freshly cracked black pepper to taste

Instructions
 

  • Prepare the Sweet Potatoes: Begin by peeling your sweet potatoes.
    Make sure to remove all the skin so that the final mash is silky and smooth.
    Once peeled, cut the sweet potatoes into evenly sized cubes, about 1–2 inches each.
    Uniform pieces ensure that the potatoes cook at the same rate and become tender without overcooking.
  • Boil the Sweet Potatoes: Place the cubed sweet potatoes into a large pot.
    Fill the pot with enough water to fully cover the potatoes, and add a pinch of salt to the water to enhance their natural flavor.
    Bring the water to a rolling boil over medium-high heat.
    Once boiling, reduce the heat to medium and let the potatoes simmer gently.
    Cook them for approximately 15–20 minutes, or until a fork slides easily through the cubes without resistance.
  • Drain the Potatoes: When the sweet potatoes are tender, carefully pour them into a colander to drain the water.
    Give them a gentle shake to remove any excess water, as this helps prevent the mash from becoming watery.
  • Sauté the Garlic: While the sweet potatoes are draining, melt 1 tablespoon of butter in a small skillet over medium heat.
    Add the crushed garlic cloves to the melted butter. Sauté the garlic for 1–2 minutes, stirring constantly, until it becomes fragrant and lightly golden.
    Be careful not to burn the garlic, as this can make it bitter.
    The butter and garlic combination will infuse the potatoes with a rich, aromatic flavor.
  • Return Potatoes to the Pot: Once drained, return the sweet potatoes to the same pot.
    Pour in the sautéed garlic along with the melted butter, ensuring all the garlic pieces are evenly distributed among the potatoes.
  • Add Dairy Ingredients: Pour ½ cup of 1% milk and 2 tablespoons of light sour cream into the pot with the sweet potatoes.
    These ingredients add creaminess and help create a smooth texture without making the mash heavy.
  • Mash the Potatoes: Using a potato masher or a hand mixer, begin mashing the sweet potatoes together with the garlic, butter, milk, and sour cream.
    Work the mixture until it reaches a smooth and creamy consistency, without large lumps.
    If you prefer a silkier texture, you can gradually add a little more milk, one tablespoon at a time, until it reaches your desired consistency.
  • Season the Mash: Taste the mashed sweet potatoes and season them with salt and freshly cracked black pepper.
    Adjust according to your preference, keeping in mind that the garlic and butter already provide a subtle savory flavor.
    Mix well to ensure the seasoning is evenly incorporated throughout the mash.
  • Serve and Enjoy: Transfer the mashed sweet potatoes to a serving bowl.
    For an extra touch, you can drizzle a tiny bit of melted butter on top or sprinkle with freshly chopped herbs such as parsley or chives.
    Serve warm as a comforting side dish for any meal.

Notes

  • Peel and cube sweet potatoes evenly to ensure uniform cooking.
  • Use 1% milk for a lighter mash, or substitute with almond milk for a dairy-free option.
  • Light sour cream can be swapped with Greek yogurt for added protein and tanginess.
  • Don’t overcook the sweet potatoes, or they may become waterlogged and affect texture.
  • Adjust garlic amount according to taste—roasted garlic can add a sweeter, milder flavor.
  • For extra creaminess, warm the milk before adding to the potatoes.
  • Multiply ingredients proportionally if preparing for larger gatherings.
