Instructions

Step 1: Roast the Sweet Potatoes

Preheat your oven to 375°F (190°C). Place the sweet potatoes directly on a baking sheet lined with parchment paper to prevent sticking and facilitate easy cleanup. Pierce each potato a few times with a fork to allow steam to escape during roasting, which prevents bursting and ensures even cooking. Roast the sweet potatoes for approximately 45 to 60 minutes, or until they are tender when pierced with a fork or skewer. The roasting process concentrates their natural sweetness and imparts a smoky aroma, which enhances the overall flavor of the pie.

Once cooked, remove the sweet potatoes from the oven and allow them to cool slightly—about 10-15 minutes—so they can be handled safely. While still warm, peel the skins away using a paring knife or your fingers, taking care to discard the skins and retain the flesh. For easier handling, you may cut the sweet potatoes into chunks before mashing.

Step 2: Prepare the Crispy Onion Crust

While the sweet potatoes are roasting, focus on creating the crispy onion crust. In a large skillet or frying pan, melt the butter over medium heat. Once melted and bubbling, add the thinly sliced onions. Use a sharp knife or mandoline to ensure uniform slices—about 1/8 inch thick—for even cooking and crispiness. Stir the onions occasionally to coat them evenly with butter and prevent sticking or burning.

Cook the onions until they turn a deep golden brown, about 15-20 minutes. They should be crispy yet not burnt, so adjust the heat as needed. Once golden and crispy, transfer the onions to a paper towel-lined plate to drain excess butter and cool slightly.

In a mixing bowl, combine the crispy onions with the flour and a pinch of salt, mixing thoroughly. This mixture will serve as the crust’s base. Transfer the onion-flour mixture into your pie dish and press it evenly across the bottom, creating a compact crust. You can use the back of a spoon or your fingers to press firmly, ensuring the crust adheres well and provides a sturdy base for the filling.

Step 3: Prepare the Filling

Peel the roasted sweet potatoes carefully, then transfer the flesh to a large mixing bowl. Mash them thoroughly using a potato masher, fork, or electric mixer until smooth and free of lumps. The goal is a silky, uniform consistency that will meld seamlessly with the miso mixture.

In a separate bowl, whisk together the miso paste, eggs, heavy cream, brown sugar, cinnamon, nutmeg, and ginger until well combined. Use a whisk to incorporate air and ensure a smooth, homogeneous mixture. Season with salt and pepper to taste, keeping in mind that miso paste is naturally salty, so taste before adding extra salt.

Combine the mashed sweet potatoes with the miso mixture, folding gently until thoroughly integrated. This step requires careful mixing to allow the flavors to meld while maintaining the smooth texture of the filling.

Step 4: Assemble the Pie

Pour the sweet potato and miso filling into the prepared crispy onion crust. Use a spatula or spoon to spread the filling evenly, smoothing the top for a neat presentation. The filling should fill the crust to just below the rim of the pie dish, ensuring it doesn’t overflow during baking.

Step 5: Bake the Pie

Place the assembled pie on the middle rack of your preheated oven. Bake at 375°F (190°C) for approximately 35-40 minutes, or until the filling is set and the top is lightly browned. To check for doneness, gently shake the pie dish; the filling should jiggle slightly but not be liquid. Insert a toothpick or a thin knife into the center—if it comes out clean, your pie is ready.

Allow the pie to cool for at least 15 minutes on a wire rack before slicing. This resting period helps the filling set further, making slicing cleaner and presentation more attractive.

Preparation Tips

• Choose firm sweet potatoes: They roast evenly and develop a rich flavor without becoming overly mushy.
• Uniform onion slices: Use a mandoline or sharp knife for thin, consistent slices, ensuring even crispiness.
• Pre-cook the crust: If you prefer a firmer crust, bake it for 10 minutes before adding the filling.
• Adjust spices: Tailor the spice levels to your taste—adding more cinnamon or ginger for warmth or reducing sugar for a less sweet profile.
• Use room temperature eggs: To facilitate emulsification and prevent curdling in the filling.
• Test crispiness: Keep an eye on the onion crust during frying; remove once it reaches your preferred crunch level.

Nutritional Information

Tips and Tricks

• Enhance flavor depth: Adding a splash of soy sauce to the miso mixture can amplify umami.
• Make ahead: Prepare the sweet potato mash and crispy onion crust a day in advance; assemble and bake just before serving.
• Use different miso types: Experiment with red or mixed miso for richer, more complex flavors.
• Adjust sweetness: For a less sweet pie, reduce the brown sugar or omit it entirely.
• Veggie variation: Add finely chopped spinach or kale to the filling for added greens.

Add-ons

• Cheese: A sprinkle of crumbled feta or grated Parmesan on top before baking can add a savory note.
• Herbs: Fresh thyme, rosemary, or chives can brighten the flavor profile.
• Nuts: Toasted pecans or walnuts sprinkled on top add crunch and richness.
• Extras: A drizzle of honey or balsamic glaze can elevate the dish as a finishing touch.

Side Dishes

• Fresh greens: A simple arugula or spinach salad dressed with lemon vinaigrette complements the richness of the pie.
• Roasted vegetables: Brussels sprouts, carrots, or parsnips roasted lightly with herbs.
• Grain options: Quinoa, wild rice, or a hearty pilaf can serve as a base.
• Pickles or chutneys: Acidic accompaniments enhance the savory elements.

Improvements and Variations

• Vegan adaptation: Replace eggs with flaxseed meal (1 tablespoon flaxseed + 3 tablespoons water per egg), swap heavy cream for coconut cream or almond milk, and use vegan butter.
• Low-sodium version: Use low-sodium miso and reduce salt in the crust and filling.
• Crust alternatives: Consider a crust made from crushed gluten-free crackers or a nut-based crust for added flavor.
• Flavor infusions: Incorporate garlic, smoked paprika, or cayenne pepper into the filling for additional layers of taste.

Save and Store

To store leftovers, allow the pie to cool completely, then cover it with plastic wrap or transfer to an airtight container. It can be refrigerated for up to 3 days. For longer storage, wrap tightly in aluminum foil and freeze for up to 1 month. To reheat, place the pie slices in a preheated oven at 350°F (175°C) for about 15 minutes or until warmed through, or microwave in short bursts, being cautious not to overheat and compromise texture.

FAQ
