You have two good options:
Option A: Paper towel wrap (best balance)
-
Wrap the sweet potato in a slightly damp paper towel.
-
Place on a microwave-safe plate.
Option B: Open plate (more “baked” skin feel)
-
Put the sweet potato directly on the plate.
-
Skin may be slightly drier, but it’s still fluffy inside.
If you want extra even steaming, place it in a microwave-safe bowl with a loose lid or cover (not airtight).
Step 5: Microwave in intervals (time guide below)
Start with the recommended time for your size. Then flip and continue if needed. Microwaves vary, so think of the times as a starting point.
Microwave Sweet Potato Cook Times (High Power)
Small (4–6 oz / 115–170 g):
-
3–4 minutes total
Flip at halfway.
Medium (7–9 oz / 200–255 g):
-
5–6 minutes total
Flip at 3 minutes.
Large (10–12 oz / 285–340 g):
-
7–9 minutes total
Flip at halfway.
Extra-large (13–16 oz / 370–450 g):
-
10–12 minutes total
Flip at halfway, then add 1-minute bursts.
Rule of thumb: If you’re unsure, undercook slightly and add 30–60 seconds at a time.
Step 6: Rest for 2–3 minutes (this is the secret!)
When the microwave stops, let the sweet potato rest on the plate for 2–3 minutes. It continues cooking from residual heat and becomes more evenly soft.
Skipping this rest is a common reason people think the center is “still hard.”
Step 7: Check doneness properly
A sweet potato is done when:
-
it feels soft when you squeeze gently (use a towel—hot!)
-
a fork slides in easily with little resistance
If the center is still firm, microwave in 30–60 second bursts until tender.
How to Cut and Fluff (So It Looks Like the Photo)
-
Slice lengthwise down the center (don’t cut all the way through if you want a “boat”).
-
Pinch the ends gently to open it up.
-
Use a fork to fluff the inside.
-
Add butter, salt, pepper—or your favorite toppings.
That fork fluffing step is what turns “soft” into cloud-like and fluffy.
Common Microwave Sweet Potato Problems (and Fixes)
Problem 1: Dry, tough texture
Causes:
-
cooked too long at once
-
no moisture protection (very dry microwave environments)
-
potato was old or stored too long
Fixes:
-
wrap in a damp paper towel
-
cook in intervals and rest
-
add butter or a drizzle of olive oil after cooking
Problem 2: Hard center, overcooked ends
Causes:
-
potato too thick or uneven shape
-
didn’t flip halfway
-
didn’t rest after cooking
Fixes:
-
flip halfway every time
-
rest 2–3 minutes
-
choose evenly shaped potatoes
-
for very thick potatoes: microwave 70% of time, rest, then finish in bursts
Problem 3: Sweet potato “exploded”
Cause: not poked enough
Fix: poke 8–12 holes all around next time

Meal Prep Ideas: Cook Once, Use All Week
Microwave sweet potatoes are incredible for meal prep because they store well and reheat easily.
Make sweet potato mash
-
Scoop out flesh
-
Mash with butter, salt, and a splash of milk
-
Store for bowls, sides, or baby food
Build fast bowls
-
Sweet potato + protein (chicken, tuna, beans)
-
Add greens (spinach, arugula)
-
Add sauce (ranch, tahini, vinaigrette)
Use in soups
Dice cooked sweet potato into:
-
vegetable soup
-
lentil soup
-
curry coconut soup
How to Store and Reheat
Refrigerate
Store cooked sweet potatoes in an airtight container for up to 4 days.
Freeze
Yes—freeze cooked sweet potatoes (whole or mashed) up to 3 months. Texture becomes softer after thawing, which is perfect for mash or soup.
Reheat
-
Microwave: 1–2 minutes (split first for even heat)
-
Oven/toaster oven: 350°F (175°C) for 10–15 minutes for drier skin
Flavor Boosters (Tiny Additions, Big Difference)
-
A pinch of salt makes sweet potatoes taste sweeter (seriously).
-
Black pepper adds contrast and depth.
-
Smoked paprika gives a “roasted” vibe even without the oven.
-
Cinnamon + salt is the best sweet combo.
-
A squeeze of lime with chili powder is a top-tier savory trick.
Frequently Asked Questions
Can you microwave sweet potatoes without wrapping them?
Yes. Wrapping simply helps keep moisture in and can lead to a softer texture. If you like slightly drier skin, cook uncovered.
Should I poke holes in sweet potatoes before microwaving?
Yes—always. It prevents pressure buildup and improves even cooking.
How long should I microwave 2 sweet potatoes at once?
Add about 2–4 extra minutes total, depending on size. Arrange them with space between and rotate/flip midway.
Is a microwave sweet potato as healthy as baked?
Yes. Microwaving is a gentle cooking method that preserves nutrients well because cook time is short.
