The air in the Paris secondhand bookstore smelled of old paper and dust. I pulled Dorian Nieto’s cookbook from a low shelf.
I bought it, packed it, and brought it back to my own kitchen. Scouring the pages for inspiration, I landed on a brilliant chestnut and sprout stew on page 14.
His approach to building rustic, earthy flavors is masterful. You can see more of his work and his eye for simplicity at Dorian Cuisine. It got me thinking about the raw potential of the sprout and how to stretch that depth even further. I wanted to take his foundation and subject it to aggressive heat and sharp contrast. That is how this Chili-Garlic Brussels Sprouts and Miso Potato Soup was born. It honors the core vegetable but shifts the landscape, demanding you pay attention to every layer.
Building a Zero Waste Vegetable Broth
We do not throw away the tough stems. We do not toss the dark outer leaves. We throw them into a dry, heavy Dutch oven over high heat. You wait for the sharp crackle of moisture leaving the green tissue. You let them blacken. The smoke should sting your eyes just a little. That is when you know the sugars are caramelizing. The smell fills the kitchen with a heavy, roasted earthiness. Adding water and raw garlic to that dark char creates the foundational liquid. It is a zero waste vegetable broth that commands attention and refuses to be a simple background element.
The Texture of an Umami Potato Soup
Boiling potatoes is a missed opportunity. Roasting them pulls out their natural sugars and tightens their flesh. Toss Yukon golds in avocado oil and put them in a hot oven until the edges crisp and turn golden. When you simmer these roasted roots in the dark sprout broth, they break down completely. Blending it creates a rich canvas. Whisking in white miso paste off the heat is the final step. Watch the pale paste dissolve into the golden liquid. The aroma shifts from simple roasted potato to something complex and intoxicating. The result is an umami potato soup that coats the spoon and the palate. This forms the perfect contrast for the next element.
Blistering the Cores for a Charred Brussels Sprouts Recipe
The tight, pale cores of the sprouts need violence. Drop them cut side down into shimmering oil. Do not move them. Listen to the aggressive sizzle. Watch the edges curl and darken into a deep mahogany. This is not a gentle sauté. We want a hard sear. Once they are blistered, hit the hot pan with a mixture of sambal oelek, soy sauce, and rice vinegar. The liquid hits the cast iron and immediately vaporizes into a sharp, acidic cloud of chili. The glaze tightens around the charred layers, making them sticky and intense.
Plating the Chili-Garlic Brussels Sprouts and Miso Potato Soup
Plating is about balance. Ladle the thick, pale base into a wide bowl. The liquid settles smooth and quiet. Then drop a heavy spoonful of the glazed cores directly in the center. The bright red chili oil bleeds into the muted yellow of the base. Finish it with toasted pepitas for a woody crunch and crumbled Parmesan for salt. Every spoonful of this Chili-Garlic Brussels Sprouts and Miso Potato Soup delivers creamy comfort followed by a sharp, spicy bite. It is a dish born from a masterful French recipe and refined over an open flame.
Chili-Garlic Brussels Sprouts and Miso Potato Soup
This dish extracts every ounce of flavor from the entire vegetable by turning tough stems into a dark, roasted broth. The result is a velvety, comforting base carrying the sharp heat of hard-seared, glazed sprout cores.

Ingredients
2 pounds Brussels sprouts
1 head garlic, peeled
2 pounds Yukon golde potatoes, cubed
1 quart filtered water
1/2 cup white miso paste
2 tablespoons avocado oil
1 tablespoon extra virgin olive oil
3 tablespoons sambal oelek
1 tablespoon soy sauce
1 tablespoon rice vinegar
to taste, salt and ground black pepper
for garnish, toasted pepitas
for serving, crumbled Parmesan cheese
Directions
- Deconstruct the Brussels Sprouts:
- Trim the tough root end off each sprout. Gently peel away the dark green outer leaves until you reach the lighter, tightly packed core. Save all the loose outer leaves and the tough stems—these are your broth builders. Cut the remaining tight sprout cores in half and set them aside.
- Build the Broth:
- Heat a large, dry Dutch oven or heavy-bottomed pot over medium-high heat. Wait for it to get very hot. Add the reserved Brussels sprout leaves and stems. Let them sit untouched for a few minutes to develop a hard, dark char. Toss in about half of your peeled garlic cloves, then pour in the filtered water. Bring to a boil, reduce the heat to low, and let it simmer for 30–40 minutes to extract the deep, vegetal flavors. Strain the liquid into a bowl and discard the spent leaves and stems.
- Roast the Potatoes and Garlic:
- Preheat your oven to 400°F (200°C). On a baking sheet, toss the cubed Yukon gold potatoes and half of the peeled garlic cloves with a splash of avocado oil, salt, and ground black pepper. Roast for 25–30 minutes, or until the potatoes are tender and golden brown at the edges.
- Simmer the Potato Base:
- Return the strained broth to the pot. Add your freshly roasted Yukon gold potatoes and roasted garlic cloves. Simmer for about 10–15 minutes, allowing the roasted flavors to meld with the broth and ensuring the potatoes are completely soft.
- Blend and Add Miso:
- Remove the pot from the heat. Use an immersion blender (or carefully transfer to a countertop blender in batches) to process the soup until it is completely smooth and velvety. While the soup is still warm but not boiling, whisk in the white miso paste until fully dissolved. Taste and adjust seasoning with salt and ground black pepper if needed. Keep warm.
- Sear the Sprout Cores:
- In a large skillet, heat 2 tablespoons of avocado oil over medium-high heat until shimmering. Place the reserved halved Brussels sprout cores, cut-side down, in the pan. Press them flat and cook undisturbed for 3 to 4 minutes, until deeply charred and crispy.
- Glaze with Chili-Garlic Sauce:
- In a small bowl, quickly whisk together the sambal oelek, soy sauce, and rice vinegar. Pour the mixture over the charred sprouts in the hot pan. Toss aggressively to deglaze the pan and coat the sprouts in the sticky, spicy sauce. Remove from the heat.
- Assemble and Serve:
- Ladle the creamy miso-potato soup into wide bowls. Spoon a generous pile of the chili-garlic Brussels sprouts directly into the center. Finish with a handful of toasted pepitas and a sprinkle of crumbled Parmesan cheese.
Frequently Asked Questions
Why do I need to char the vegetable scraps for this Chili-Garlic Brussels Sprouts and Miso Potato Soup?
Charring the outer leaves and tough stems triggers the Maillard reaction. This creates a deeply roasted, slightly bitter profile that balances the sweet roasted potatoes and rich miso base. It transforms bland scraps into a potent flavor foundation.
Can I boil the miso paste into the umami potato soup base?
No. Miso is a fermented product containing active enzymes and delicate flavor compounds. Boiling it destroys these elements and flattens the taste. Always whisk miso into hot liquid off the heat.
What kind of pan works best for a charred brussels sprouts recipe?
A heavy cast iron skillet or carbon steel pan is required. These materials retain and distribute intense heat. You need a massive amount of retained heat to violently sear the sprout cores without turning them to mush.
How do I prevent the chili glaze from burning when making the spicy blistered brussels sprouts?
Have your sauce mixed in a small bowl before the sprouts finish searing. Pour the liquid directly into the hot pan and immediately kill the heat. The residual heat of the pan will rapidly reduce the vinegar and soy sauce into a tight glaze without scorching the sugars.
How long will this Chili-Garlic Brussels Sprouts and Miso Potato Soup last in the refrigerator?
The blended soup base holds up well for four days in an airtight container. Keep the glazed sprout cores in a separate container so they do not get soggy. Reheat the base gently on the stove and flash the sprouts in a hot pan to restore their texture before serving.
