    3 Hacks for Easy Kabocha Squash Pie

    1. Use the Frozen Pie Shells or Pie Crusts

    Store-bought pie crusts are great for a beginner baker.  Making your own pastry shell can be challenging and time consuming, especially if you’ve never tried making it before.  For this Kabocha Squash Pie recipe, you can purchase a ready-made pie shell from your grocer’s freezer.

    What brand should you buy?  Personally, I like Wholly Wholesome Organic Traditional 9″ Pie Shells because even without blind baking (read the next section), the bottom of the crust does not get soggy!  The crust texture is light and flaky with crisp edge, and it has toasty buttery flavors that are quite delicious.  It also comes with on a pie dish so you don’t need to purchase additional pie trays.

    I’ve also tried Trader Joe’s pie sheet and it’s one of our favorites as well.  But Trader Joe’s Pie Crusts are pastry sheet, which requires your own pie dish.  If you don’t bake often, pie shell I mentioned above might be a better choice.

    2. Steam Kabocha 

    Most of you probably roast/bake pumpkins and squash in the oven.  However in Japan, steaming or microwaving kabocha is the mainstream.  Maybe it’s because we don’t have an American-size oven and roasting is not a common cooking method in Japan.

    From my own cooking experience, I recommend steaming kabocha.  It only requires 15 minutes of steaming (vs. 45-60 minutes of roasting/baking at 400F).  Also, steaming helps retain the moisture content in the kabocha during the cooking process.

    3. Use Pumpkin Pie Spice

    For those of you who’re not in the U.S., pumpkin pie spice is an American spice mix commonly used in pumpkin pie and pumpkin spice latte (or pumpkin smoothie for a healthier version).  It’s a really convenient spice to have during the holiday season.

    It is generally a blend of powdered cinnamon, nutmeg, ginger, cloves, and all spice.  If you can’t get this spice, you can mix 1 tablespoon ground cinnamon, 2 teaspoons ground ginger, 1/2 teaspoon allspice, 1/2 teaspoon ground cloves, and 1/2 teaspoon ground nutmeg for about 2 tablespoon of homemade pumpkin pie spice blend.

    Prebake or Not to Prebake Pie Crust

    Pre-baking the pie crust before adding the filling is called “Blind Bake” and most of pies, tarts, and quiches call for pre-baking.

    This technique is used to make sure the bottom of the pie is crisp and will hold up the soggy contents.  Also, it’s good to pre-bake when your pie is going to spend minimal time in the oven.

    One drawback for blind bake is that you will need to account for an additional 1 hour or so to the cooking process.  15-20 minutes to blind bake, then another 30 minutes for the crust to cool before adding the filling and bake again.  While it requires extra cooking time, the investment is well worth it to prevent soggy bottoms and blown out pie crust.

    For this recipe, I skipped the blind bake process.  The pie crust I used held up the filling very well and the bottom of the crust never got soggy with the kabocha filling.  If you’re using pie shells/crusts that are known for soggy crusts, I definitely recommend pre-baking.  I put the instruction for pre-baking in the recipe.

    3 Cool Kitchen Tools

    1. Stainless Steel Steamer Basket

    Stainless Steel Steam Basket.If you don’t have a steamer basket, I recommend you to invest in this stainless steel steamer basket ($8 on Amazon) that can be in pans and pressure cookers.

    You can steam vegetables, eggs, and even fish!  I especially like it because it’s dishwasher friendly and collapsible for easy storage!  You can use how I used the stainless steel steamer basket in the kabocha squash pie video.

    2. Food Processor 

    Food ProcessorIf you do a lot of pureeing, a big food processor like this is very helpful.  I used to have a smaller food processor so I had to puree vegetables in batches.

    This 14 cup food processor is big enough for most of pureeing job I have to do.

    One negative thing about this food processor is that it’s quite big and takes up a big space in your kitchen cabinet.

    3. Fine Mesh Strainer

    uragoshiki For those of you who don’t own a food processor or blender, this fine mesh strainer or similar one ($10 on Amazon) is a cool tool to have!

    In Japanese cooking, we use this fine mesh strainer instead of a food processor or blender because there is no space in a typical Japanese kitchen for these gadgets. 🙂

    Course: Dessert
    Cuisine: Japanese
    Keyword: homemade pie, pumpkin pie
    Servings: 1 (9" or 23 cm pie)
    Author: Nami
    • 2.5 lb kabocha squash/pumpkin (2.5 lb = 1134 g) (with seeds and skin)
    • 2 Tbsp unsalted butter (2 Tbsp = 30 g)
    • 2 Tbsp sugar (2 Tbsp = 30 g)
    • 1 large egg yolk
    • 2 large eggs
    • cup brown sugar (⅓ cup = 72 g)
    • 2 tsp pumpkin pie spice
    • ½ tsp salt (kosher or sea salt; use half if using table salt)
    • 1 Tbsp rum
    • 200 ml heavy (whipping) cream (200 ml = ¾ cup + 2 Tbsp)
    • 1 pie crust
    Whipped Cream:
    • 1 cup heavy (whipping) cream (1 cup = 240 ml)
    • 2 Tbsp sugar
    1. Gather all the ingredients.
    [Optional] Blind Baking – Please read the blog post first
    1. Preheat the oven to 400F (200C). Take out the pie crust from the freezer and thaw for 10 minutes.
    2. When the pie crust has softened a little bit, prick both bottom and sides of the pie crust with a fork, make sure not to poke through. This allows steam to escape and prevents bubbles from forming from the bottom of the crust. Alternatively, you can use pie weights. Bake the pie crust for 15-20 minutes or until golden brown. Remove from the oven, let it cool until room temperature.
    Kabocha Squash Pie
    1. Put 1 cup of water into the pan (I use a wok) and place the steamer basket on top.
    2. With a very firm chef’s knife, cut kabocha in half and scoop out seeds. Cut squash into 1½ inch (4 cm) cubes.
    3. Place kabocha cubes in a steamer basket and cover with lid. Turn heat to high and steam for 15 minutes.
    4. After 15 min, check if kabocha ready by inserting the skewer into a thick kabocha cube. If it goes through smoothly, then they’re done. Otherwise, keep steaming and check back in 1 minute. Remove the steamer basket from the pan. When the kabocha is cool enough for you to touch, remove the skin with a knife.
    5. Transfer the kabocha to a food processor or blender. Puree kabocha until smooth. Since the kabocha was steamed and contains a good amount of moisture, you don’t need to add any liquid. However, if the kabocha has been sitting out too long and seems dehydrated, add 1 Tbsp. water at a time to help it pureed. My pumpkin squash yield about 3 cups (675 g). For this recipe, you will need 2 cups (450 g) pureed kabocha squash.
    6. If you don’t have a food processor or blender, transfer kabocha to a large bowl and mash with a fine mesh strainer like this to pass through kabocha for finer texture. You can also use a potato masher but it won’t be as refined.
    7. Preheat the oven to 400F (200C). Take out the pie crust from the freezer and thaw for 10 minutes.
    8. In a large bowl, combine 2 Tbsp. (30 g) unsalted butter and 2 Tbsp. (30 g) granulated sugar. Whisk until it’s creamy consistency.
    9. Add 1 egg yolk and 2 eggs, one at a time and whisk well to combine before adding next one.
    10. Add 2 cups (450 g) pureed kabocha and mix well to combine.
    11. Add ⅓ cup (72 g) brown sugar, 2 tsp. pumpkin pie spice, and ½ tsp. kosher salt into the bowl and mix all together.
    12. Add 1 Tbsp. rum and ¾ cup + 2 Tbsp. (200 ml) heavy whipping cream and whisk well.
    13. Pour the filling into the pie crust. Tap the crust on the counter a few times to make sure there is no air gap in the fillings.
    14. Bake at 400F (200C) for 15 minutes and then reduce oven temperature to 350F (180C) and bake for 50 minutes, or until the skewer inserted near the center comes out clean. If you pre-baked the pie crust, you might need to shield the edges with foil to avoid the crust becoming too brown and overdone.
    15. Cool on wire rack for 2 hours. Serve immediately or refrigerate up to 3 days. Serve the pie with a big dollop of fresh whipped cream (recipe follows).
    Whipped Cream
    1. [Optional] Place a metal mixing bowl and metal whisk into the freezer for 10 to 15 minutes (If you don’t use an electric mixer, this step helps you to make whipped cream faster).
    2. Add 1 cup (240 ml) heavy whipping cream and 2 Tbsp. sugar into the mixing bowl. Whisk just until the cream reaches stiff peaks.
    3. Store any unused portion in an airtight container for up to 24 hours. When ready to use, re-whisk for 10 to 15 seconds.
