This Weight Watchers crustless sweet potato pie delivers all the cozy, spiced comfort of traditional pie without the guilt or the crust. 💛 The secret lies in a lighter filling made with egg whites, Greek yogurt, and just the right amount of maple syrup—keeping the flavor rich while cutting calories.
I developed this recipe after realizing how much I missed sweet potato pie during my own WW journey, and it’s become a staple dessert that actually satisfies cravings.
The filling is where the magic happens: roasted sweet potatoes create natural sweetness, while cinnamon, nutmeg, and vanilla extract build warmth without overpowering. Using egg whites instead of whole eggs cuts fat while keeping the pie tender, and Greek yogurt adds creaminess without heavy dairy.
The result? A slice that’s perfectly spiced, velvety, and light enough to enjoy without derailing your points.
Baking is straightforward—just mix, pour, and bake at 375°F for 40 minutes until set. The texture is silky, not dense, and the aroma alone will fill your kitchen with fall comfort.
This pie fits 4 Weight Watchers PointsPlus servings, making it a guilt-free treat for gatherings or solo indulgence. No one will guess it’s a diet-friendly version.
Serve warm with a dollop of Greek yogurt or a sprinkle of cinnamon for extra flair. The best part? Leftovers stay moist and delicious for days, so you can bake ahead and enjoy without the fuss. Let’s make this pie—your taste buds (and waistline) will thank you.
Ingredients for weight watchers crustless sweet potato pie
Six simple ingredients transform into a lighter sweet potato pie that fits Weight Watchers perfectly.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Peeled and roasted until tender |
| Egg Whites 🥚 | 4 large | Room temperature for best blending |
| Plain Nonfat Greek Yogurt 🥛 | ½ cup | Full-fat for richer texture |
| Pure Maple Syrup 🍯 | ¼ cup | Grade B for deeper flavor |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated for best flavor |
| Vanilla Extract 💧 | 1 tsp | Pure alcohol-free preferred |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Unsweetened Almond Milk 🥛 | ¼ cup | For lightness and creaminess |
| Powdered Sugar 🍚 | ¼ cup | For topping (optional) |
Sweet potatoes are the star here. Orange-fleshed varieties like Garnet or Jewel work best—they’re naturally sweeter. Roast them until fork-tender (about 45 minutes at 400°F), then mash until smooth. Trader Joe's or Whole Foods usually carry the best quality, but any grocery store will do. Skip the pre-mashed cans—they’re watery and lack flavor. For extra richness, roast with a drizzle of olive oil, but it’s not required. The Greek yogurt is non-negotiable for creaminess without heavy dairy—Fage 0% is my go-to, but any plain nonfat will work.
No maple syrup? Agave nectar or honey works in a pinch, but maple’s depth is worth it. Freshly ground spices make all the difference—if you’ve got whole nutmeg, grate it yourself. Vanilla extract can be imitation, but pure alcohol-free (like McCormick) adds better flavor. For a lighter texture, almond milk replaces some of the yogurt—just use the same amount. The powdered sugar topping is optional but adds that classic pie finish. Store-bought pie crust crumbs work if you’re craving crust texture, but this version stands alone beautifully.
This pie keeps for 4 days in the fridge, covered tightly. Reheat slices at 350°F for 10 minutes—they’ll stay moist. For make-ahead baking, assemble the pie and refrigerate overnight before baking. It actually tastes better the next day as flavors meld. Freeze for up to 3 months by wrapping tightly in plastic. Portion into single servings for easy grab-and-go desserts—perfect for Weight Watchers points tracking!

Step-by-step instructions for Weight Watchers crustless sweet potato pie
Here's how to create a light, spiced dessert that tastes indulgent but fits your goals.
🍳 Step 1: Roast the Sweet Potatoes Until Silky
Preheat your oven to 400°F and pierce the 2 whole large sweet potatoes with a fork in several places. Place them on a baking sheet and roast for 45-50 minutes until completely tender when pierced with a knife. The insides should be soft enough to mash easily with a fork.
While they roast, here's the thing—don't skip the piercing. It prevents steam buildup that could make them tough. Also, I like to flip them halfway through cooking for even browning. Once they're done, let them cool slightly before handling—they'll be hot!
👨🍳 Step 2: Make the Spiced Filling Mixture
In a large mixing bowl, scoop out all the flesh from the roasted sweet potatoes and mash them until completely smooth. Add the 0.5 cup plain nonfat Greek yogurt, 0.25 cup pure maple syrup, 1 tsp vanilla extract, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.25 tsp salt. Mix until fully combined and smooth.
This is where the magic happens—the spices should be evenly distributed. I like to taste the mixture at this point to adjust sweetness or spice level. You want it to be rich and aromatic, with the cinnamon and nutmeg really singing. If it looks too thick, add 1-2 tablespoons of the unsweetened almond milk to loosen it.
🍳 Step 3: Whip the Egg Whites to Stiff Peaks
In a separate, very clean bowl, beat the 4 large egg whites with an electric mixer on medium speed until soft peaks form. Gradually increase to high speed and continue beating until the egg whites form stiff peaks that hold their shape when the whisk is lifted. This should take about 3-4 minutes total.
Here's the crucial part: make sure your bowl is completely free of any grease or oil. Even a tiny bit can prevent the egg whites from whipping properly. I like to wipe the bowl with a damp paper towel before starting. The egg whites should be glossy and hold their shape when you lift the whisk.
🥘 Step 4: Fold Everything Together Gently
Using a spatula, gently fold one-third of the whipped egg whites into the sweet potato mixture to lighten it. Then fold in the remaining egg whites in two additions, being careful not to deflate them. The goal is to create a smooth, airy batter that's ready for baking. You should see some white streaks throughout.
This is where patience pays off. Go slow and use long, gentle strokes from the bottom of the bowl upward. If you see the batter starting to look curdled or lose its volume, you've overmixed. The final mixture should be thick but still pourable, with a beautiful marbled appearance from the folded egg whites.
🔥 Step 5: Bake Until Set and Golden
Pour the batter into a 9-inch pie dish (or similar size) that's been lightly greased with cooking spray. Bake at 350°F for 40-45 minutes until the center is just set and the edges are golden brown. The pie should jiggle slightly in the center but not be completely liquid when you gently shake the dish.
Don't overbake—this pie sets as it cools. I like to check for doneness at the 35-minute mark by inserting a knife in the center. It should come out clean but slightly moist. If you're using the optional 0.25 cup powdered sugar topping, sprinkle it evenly over the pie during the last 5 minutes of baking for a sweet crust.
Pro Tips For Making Weight Watchers Crustless Sweet Potato Pie
- Boil Until Fork-Tender: Don’t rush the sweet potatoes—test for doneness by piercing them with a fork. If it slides in like butter, they’re ready. Overcooked ones turn to mush, and you’ll end up with a watery filling instead of a creamy texture.
- Strain the Yogurt: Thin Greek yogurt can make your pie filling too runny. Strain it through a clean kitchen towel or cheesecloth for 10 minutes before mixing—this removes excess liquid without sacrificing creaminess. (Yes, it’s weird, but it works.)
- Prevent Egg White Curdling: Whisk the egg whites until frothy, then gently fold them into the warm filling. If the mixture is too hot, the whites will cook immediately and turn rubbery. Let the filling cool to room temp first—just enough to keep the whites light and airy.
- Maple Syrup First: Add the pure maple syrup to the warm sweet potato purée before mixing in the yogurt and spices. This ensures even distribution and prevents clumping. Stir in the cinnamon last to avoid settling at the bottom—trust me, you’ll notice the difference.
Serving suggestions for this weight watchers crustless sweet potato pie
Warm Serving Style
Serve this pie warm straight from the oven for the most comforting experience—about 10 minutes out of the oven ensures the filling is creamy but not runny.
I like to place slices on a pre-warmed plate and drizzle with a little extra maple syrup or a dollop of Fage 0% Greek yogurt for a tangy contrast. The warmth enhances the cinnamon and nutmeg aromas, making every bite feel like a cozy hug. 💛
Classic Toppings
A sprinkle of powdered sugar adds that classic pie finish, but I also love a pinch of freshly grated nutmeg or a few drops of vanilla extract on top.
For extra flair, try a small dollop of whipped cream or a scoop of vanilla nonfat Greek yogurt—it keeps the dish light while adding richness. Skip the whipped topping if you're watching points closely.
Beverage Pairings
Pair this pie with a cup of chai tea or hot apple cider to complement the warm spices. For coffee lovers, a cinnamon-spiced latte made with unsweetened almond milk balances the sweetness beautifully. A glass of sparkling water with lemon is also a refreshing, zero-point option that cleanses the palate.
Make-Ahead Serving
Bake the pie a day ahead and store it in the fridge—it actually tastes better as the flavors meld! Reheat individual slices at 350°F for 10 minutes to restore that warm, gooey texture.
I often prepare it the night before gatherings so I can focus on other dishes. The pie keeps well for 4 days, making it perfect for meal prep.
Portion Control
This recipe serves 6 slices, each fitting 1 Weight Watchers PointsPlus serving. To make it even easier, portion the pie into single servings before baking—just use a 9-inch pie dish and cut into 6 equal wedges with a pizza cutter.
Store extras in airtight containers for grab-and-go desserts. 💡
Holiday Presentation
For special occasions, serve the pie in a glass pie dish to show off its beautiful golden color. Garnish with a few cinnamon sticks or a dusting of powdered sugar for an elegant touch.
Place it on a wooden board with a few fresh cranberries or pecans for a festive autumnal display that feels restaurant-quality.

Frequently asked questions
Can I use regular sweet potatoes instead of the orange-fleshed ones?
Yes, but expect slightly less natural sweetness. Regular sweet potatoes work fine—just roast them until very tender (about 50-55 minutes) to compensate. For extra flavor, roast them with a drizzle of olive oil or a pinch of salt. The texture will be just as creamy, though the color might be slightly paler.
What if my egg whites won't whip to stiff peaks?
This usually happens if your bowl isn't clean or the egg whites are too warm. First, make sure your bowl is completely free of grease (wipe with a damp towel). If the egg whites are warm, chill the bowl in the fridge for 10 minutes before starting. Also, use a whisk or beaters that are completely dry—even a drop of oil can prevent proper whipping.
Can I make this pie without egg whites?
Yes! For a vegan version, replace the egg whites with 0.5 cup unsweetened applesauce or 0.5 cup aquafaba (chickpea brine). The texture will be slightly denser but still delicious. If using aquafaba, whip it to stiff peaks first, just like egg whites. For binding, add 1 tbsp cornstarch to the sweet potato mixture to help thicken it during baking.
Why does my pie look dense instead of silky? Overmixing the filling or underbaking are the most common causes.
How do I adjust the sweetness for kids or picky eaters?
Add 1-2 extra tablespoons of maple syrup to the filling, or sprinkle 1-2 tablespoons of brown sugar on top before baking. For a sweeter version, you can also reduce the almond milk to 1 tablespoon and increase the Greek yogurt to 0.6 cup (it's naturally sweeter). Always taste the filling before baking—adjust gradually!
