Tuscan Chianti-Braised Mushroom Stracotto Burger

Introduction

In Tuscany, stracotto is the sacred art of slow braising until everything softens into a rich, fragrant melody. For this slow-cooked burger, we shred king oyster mushrooms and slowly simmer them in Chianti, soffritto, and garden herbs, crowning the tender glaze with a velvety cashew fonduta inside a warm olive oil bun.

Ingredients

• 500g king oyster mushrooms, shredded lengthwise with a fork
• 2 tablespoons extra virgin olive oil, plus more for finishing
• 1 medium red onion, finely minced
• 1 carrot, finely minced
• 1 celery rib, finely minced
• 3 cloves garlic, crushed
• 2 tablespoons double-concentrated tomato paste
• 200ml Chianti or dry Tuscan red wine
• 250ml rich vegetable broth
• 2 sprigs rosemary and 2 sprigs fresh sage, tied with kitchen twine
• 1 dried bay leaf
• 1 cup raw cashews, soaked and blended smooth with 1/2 cup warm water, nutritional yeast, and sea salt
• 4 artisanal rosemary focaccia rolls or olive oil buns, halved
• 2 cups wild baby arugula
• Sea salt and freshly cracked black pepper, to taste

Instructions

1. Heat the extra virgin olive oil in a heavy-bottomed Dutch oven over medium-low heat.
2. Add the minced red onion, carrot, and celery with a pinch of sea salt, cooking slowly for 12 minutes until deeply aromatic and sweet.
3. Stir in the crushed garlic and double-concentrated tomato paste, cooking for 2 minutes until caramelized and brick-red.
4. Fold in the shredded king oyster mushrooms, tossing to coat with the soffritto base.
5. Pour in the Chianti wine, deglazing the bottom of the pot, and simmer gently for 5 minutes until reduced by half.
6. Add the vegetable broth, herb bundle, and bay leaf; season generously with black pepper and sea salt.
7. Cover with the lid slightly ajar, reduce heat to low, and slow-braise for 45 minutes until the mushroom fibers are melt-in-your-mouth tender and coated in a glossy, savory reduction.
8. Remove the herb bundle and bay leaf, then fold in a final swirl of olive oil.
9. Toast the halved buns on a dry skillet until golden and crisp.
10. Assemble each burger by layering the bottom bun with crisp wild arugula, a generous mound of slow-braised mushroom stracotto, a warm spoonful of silky cashew fonduta, and cap with the toasted bun top.

Serve hot with a quick thread of your freshest new-season Tuscan extra virgin olive oil and a glass of dry Chianti. Pure comfort, born of patience and garden simplicity.
