Fall is a wonderful season for cooking: the markets are full of freshly harvested vegetables and pumpkins start appearing on store shelves. When pie pumpkins arrive, I enter a few months of enjoying pumpkin in many dishes. Pie pumpkins have a sweeter, more concentrated flavor than the larger carving varieties, and they’re perfect for eating and pureeing. While pumpkin is delicious in the classic pie, it’s also lovely simply pureed with a touch of sugar and warming spices.
The sous vide method is an excellent way to cook pumpkin. Cooking the flesh in a sealed bag in a controlled water bath preserves moisture, concentrates flavor, and keeps nutrients intact. For this recipe I add butter, brown sugar, and spices into the bag so the pumpkin steeps in those flavors while it cooks. The result is a rich, smooth puree ready to use as a side dish, a pie filling, or a component in other recipes.
Choose a small pie pumpkin weighing about 4–5 pounds. These tend to be sweeter and have firmer, denser flesh than large carving pumpkins. Cut the pumpkin into quarters, remove all seeds and the stringy interior, then peel or trim off the outer skin. Slice the pumpkin flesh into roughly 1-inch wedges for even and relatively quick cooking.
Arrange the pumpkin slices in a single flat layer inside a food-safe vacuum bag so the pieces are not stacked. Sprinkle the brown sugar and spice mixture evenly over the pumpkin, then add the butter in small cubes so it melts and distributes during cooking. Seal the bag using a vacuum sealer or a reliable water-displacement method.
Set your sous vide bath to 180°F (82°C) and immerse the sealed bag. Cooking time will vary with slice thickness, but plan on 2 to 3 hours. After about two hours check for tenderness: a cooked wedge will give easily when pressed and will mash under light pressure. The pumpkin should be tender throughout, but not waterlogged.
When the pumpkin is cooked, remove the bag from the water bath, cut it open, and pour the contents — pumpkin and cooking liquid — into a bowl. Purée the mixture using a potato masher for a slightly chunky texture, or a hand blender, immersion blender, or stand mixer for a very smooth puree. The cooking liquid adds flavor, so include some of it to reach your preferred consistency.
This pumpkin purée is versatile: serve it simply as a spiced side dish, use it as the base for pumpkin pie filling, or spoon it into casseroles. For a nostalgic treat, spread the puree in the bottom of a baking dish, top with marshmallows, and bake until the marshmallows are browned and golden.
Sous Vide Spiced Pumpkin
Ingredients
- 1 pie pumpkin (about 4–5 pounds)
- 3/4 cup brown sugar
- 1/4 cup butter
- 1 1/2 tsp cinnamon
- 1 tsp ginger
- 1/2 tsp nutmeg
- 1/4 tsp cardamom
- 1/4 tsp ground cloves
- 1/2 tsp salt
Instructions
- Fill the sous vide water bath and set the temperature to 180°F (82°C).
- Cut the pumpkin into quarters. Scoop out seeds and fibrous strands and discard. Peel or trim off the outer skin, then slice the pumpkin flesh into 1-inch wedges.
- Combine the brown sugar and spices in a bowl and mix well.
- Place the pumpkin slices in a large food-safe bag in a single layer. Sprinkle the sugar and spice mixture over the pieces.
- Cut the butter into 1/2-inch cubes and add them to the bag so they are distributed over the pumpkin.
- Ensure the pumpkin slices lie flat and are not stacked. Vacuum seal the bag securely.
- Place the sealed bag in the preheated water bath and cook for 2–3 hours, depending on slice thickness.
- Remove the bag from the bath, open it, and transfer the pumpkin and any cooking liquid to a bowl. Puree with a potato masher for a rustic texture or a hand/immersion blender or stand mixer for a smooth puree.
- Serve the puree as a side dish, use it as pie filling, or incorporate it into other recipes as desired.
Notes
To make pumpkin pie: Mix 2 1/4 cups pumpkin puree with 1 1/4 cups heavy cream and 3 eggs until smooth. Pour the filling into an unbaked pie shell. Bake at 400°F for 10 minutes, then reduce the oven temperature to 350°F and continue baking for about 25 minutes, or until the edges are set and the center has only a slight jiggle when the pie is gently shaken.
Storage and reheating: Cool the puree, then refrigerate in an airtight container for up to 4–5 days or freeze for longer storage. Reheat gently on the stovetop, stirring to restore a creamy texture, or warm in a low oven.
Variations and tips: For a bolder flavor, add a splash of maple syrup or a pinch of orange zest. If you prefer less sweetness, reduce the brown sugar. The sous vide method yields a deeply flavored, evenly cooked puree that works well in both sweet and savory applications.
