What Ingredients You Will Need

This pumpkin miso paste recipe relies on simple ingredients that come together for a surprisingly complex flavor. Each one plays its part beautifully.

Pumpkin: Fresh pumpkin, roasted and pureed (approximately 2 cups of puree). Sugar pumpkins or pie pumpkins work best due to their sweet and creamy texture.
Miso paste: White or yellow miso is ideal for this recipe as it’s milder and complements the pumpkin’s sweetness.
Salt: Use unrefined sea salt to aid the fermentation process and enhance the flavors.
Maple syrup: Optional, but adds a subtle sweetness that pairs beautifully with the pumpkin and miso.
Rice vinegar: Adds acidity and helps balance the flavors.
Ground ginger: For a hint of warmth and spice.
Garlic: Minced or grated, for an extra layer of savory depth.

Feel free to adjust the ingredients to your liking. If you want a spicier kick, add a pinch of cayenne or chili flakes. For those avoiding sugar, you can skip the maple syrup—it’s still delicious without it.

Equipment Needed

Food processor: To blend the roasted pumpkin into a smooth puree.
Mixing bowls: For combining the pumpkin puree with miso and other ingredients.
Fermentation jar: A glass jar with an airtight lid is ideal for fermenting your paste.
Spatula: For scraping down the sides of your food processor and mixing ingredients thoroughly.
Measuring cups and spoons: To ensure accurate ingredient proportions.

If you don’t have a food processor, a high-speed blender or even an immersion blender can work in a pinch. Just make sure you puree the pumpkin until it’s silky smooth!

Preparation Method

Prepare the pumpkin: Preheat your oven to 400°F (200°C). Slice your pumpkin in half, scoop out the seeds, and place it cut-side down on a baking sheet lined with parchment paper. Roast for 40-50 minutes, or until the flesh is soft and easily pierced with a fork. Let it cool.
Puree the pumpkin: Scoop out the roasted pumpkin flesh and transfer it to a food processor. Blend until completely smooth. Measure out 2 cups of puree.
Mix the ingredients: In a large mixing bowl, combine the pumpkin puree, 1 cup of miso paste, 2 tablespoons of rice vinegar, 1 teaspoon of ground ginger, 1 minced garlic clove, and 1 tablespoon of maple syrup (optional). Mix everything thoroughly until well combined.
Pack into a jar: Transfer the mixture into a clean glass jar. Use a spatula to press the paste down firmly, eliminating any air pockets. Leave about 1 inch of space at the top to allow for expansion during fermentation.
Seal and ferment: Close the jar tightly and place it in a cool, dark spot. Let the paste ferment for 7-10 days. Check occasionally for any signs of mold; if you spot any, scrape it off immediately.
Taste and adjust: After 7 days, open the jar and taste the paste. If you prefer a deeper flavor, let it ferment for a few more days. Once you’re satisfied, store the pumpkin miso paste in the refrigerator to halt the fermentation process.

Remember to clean your equipment thoroughly before use to ensure proper fermentation. And don’t be alarmed by bubbles or a slight sour smell—these are signs that the fermentation is working!

Cooking Tips & Techniques

Choose the right pumpkin: Sugar pumpkins or pie pumpkins yield the best flavor and texture. Avoid using watery varieties like carving pumpkins.
Roasting is key: Roasting the pumpkin enhances its natural sweetness and adds depth. Don’t skip this step!
Fermentation temp matters: Aim for a spot that’s around 60-75°F (15-24°C). Too hot, and the fermentation may go awry; too cold, and it might not ferment properly.
Avoid contamination: Always use clean utensils and jars to prevent unwanted bacteria from interfering with the fermentation process.
Don’t rush it: The flavors develop over time, so be patient. If you’re new to fermentation, check the paste daily to observe how it evolves.

Variations & Adaptations

One of the best things about pumpkin miso paste is how versatile it can be. Here are some ideas to make it your own:

Spicy kick: Add a teaspoon of chili flakes or Sriracha for a delightful heat that pairs beautifully with the sweet pumpkin.
Seasonal twist: Swap pumpkin for butternut squash or sweet potato to explore different flavors. Both work wonderfully.
Dietary adaptations: Use coconut aminos instead of miso for a soy-free version, or choose gluten-free miso if you’re avoiding gluten.
Herb-infused option: Add a handful of chopped fresh rosemary or thyme for an herby, earthy vibe.

I once tried adding a pinch of smoked paprika, and the smoky undertones were incredible. The possibilities are endless, so don’t be afraid to experiment!

Serving & Storage Suggestions

Once your pumpkin miso paste is ready, the ways to enjoy it are endless:

Serving: Use it as a base for soups, stews, or curries. Spread it on warm crusty bread, or mix it into a dip with yogurt or sour cream.
Complementary dishes: Pair it with roasted vegetables, grilled tofu, or even as a marinade for chicken or fish. A dollop on steamed rice or noodles is heavenly.
Storage: Store the paste in an airtight container in the refrigerator. It will keep for up to 3 months, and the flavor will deepen as it ages.
Reheating: If you’re using it in hot dishes, no special steps are needed—it blends right in when stirred into soups or sauces.

Pro tip: The flavors of this paste mature and deepen over time. If you can resist the temptation, let it sit for a couple of weeks in the fridge before using it.
