Stop boiling sweet potatoes in water! This 5-star chef trick makes them melt like butter

Ingredients

• 4 pieces Sweet Potatoes (medium, uniform size, skin on)
• 1 tablespoon Baking Soda (for initial soak to loosen dirt)
• 1 tablespoon Salt (for second soak to calm enzymes)
• 2 tablespoons Olive Oil (thin coating for crisp skin; extra‑virgin recommended)
• 1 tablespoon Unsalted Butter (optional, for brushing instead of oil)
• 2 tablespoons Brown Sugar (only for casserole variation)
• 1/2 teaspoon Ground Cinnamon (only for casserole variation)
• 1 large Egg (only for casserole variation; beaten)
• 1 tablespoon Lemon Juice (only for casserole variation)
• 2 tablespoons All-Purpose Flour (only for casserole variation; helps set the bake)

Instructions

1. Select Uniform Sweet Potatoes

   Choose 4 medium sweet potatoes that are similar in size, have firm plump skin and a fresh colour. Avoid smooth or shriveled ones.

   Time: PT5M

2. Prepare Baking Soda Soak

   Fill a large basin with clean water and dissolve 1 tablespoon of baking soda. Submerge the potatoes for about 2 minutes to loosen dirt.

   Time: PT2M

3. Scrub Potatoes

   Using your hands (or a soft brush), scrub each potato to remove soil. Rinse briefly.

   Time: PT5M

4. Trim Ends

   Cut off both ends of each sweet potato – these parts are fibrous and less tasty.

   Time: PT5M

5. Prepare Salt Soak

   In another basin, add 1 tablespoon of salt to clean water and stir until dissolved.

   Time: PT2M

6. Salt Soak

   Place the trimmed potatoes in the salted water, ensuring both ends are submerged. Soak for 15 minutes.

   Time: PT15M

7. Rinse and Drain

   Rinse the potatoes once more under running water and let them drain on a clean towel.

   Time: PT2M

8. Pierce Holes

   Using a fork or a sharp knife, gently pierce several holes around each potato to allow steam to escape.

   Time: PT2M

9. Brush with Oil

   Lightly brush the entire surface of each potato with olive oil (or melted butter) for a crisp, golden skin.

   Time: PT2M

10. Roast in Oven

    Place the potatoes on a parchment‑lined baking tray (or directly on the rack). Roast at 200°C (400°F) for 20‑30 minutes, turning once halfway through.

    Time: PT30M

    Temperature: 200°C

11. Rest and Serve

    Remove the potatoes from the oven, let them cool for 2 minutes, then serve as a side or snack.

    Time: PT2M

12. Optional: Steaming Method

    If you prefer steamed sweet potatoes, bring water to a boil in a pot, insert a steaming rack, add the potatoes, cover tightly and steam 15 min on high then 15 min on medium heat.

    Time: PT35M

13. Optional: Sweet Potato Casserole

    Peel, slice and mash the steamed potatoes while hot. Stir in 1 tbsp softened butter, 2 tbsp brown sugar, ½ tsp cinnamon, a pinch of salt, 1 beaten egg, 1 tbsp lemon juice and 2‑3 tbsp flour until smooth. Transfer to a baking tray and bake at 175°C (350°F) for 25‑30 min.

    Time: PT45M

    Temperature: 175°C
