📝 About This Recipe

This elevated breakfast classic transforms humble fungi into a luxurious, bistro-quality meal using a combination of buttery textures and aromatic herbs. By searing the mushrooms until golden and deglazing with a touch of balsamic, we create a deeply savory profile that balances perfectly against creamy mascarpone and crusty bread. It is a sophisticated, vegetable-forward dish that proves breakfast can be both hearty and refined.

🥗 Ingredients

The Mushrooms

  • 500 grams Mixed Mushrooms (combination of Cremini, Shiitake, and Oyster, sliced)
  • 2 tablespoons Unsalted Butter (high quality, European style preferred)
  • 1 tablespoon Extra Virgin Olive Oil
  • 4 pieces Garlic Cloves (thinly sliced or minced)
  • 1 teaspoon Fresh Thyme (leaves stripped from the stem)
  • 1 teaspoon Balsamic Vinegar (for deglazing)

The Toast & Base

  • 2 thick slices Sourdough Bread (cut from a fresh boule)
  • 2 tablespoons Mascarpone Cheese (at room temperature for spreading)
  • 1/2 teaspoon Lemon Juice (freshly squeezed)

Seasoning & Garnish

  • 1 pinch Flaky Sea Salt (Maldon or similar)
  • 1/2 teaspoon Black Pepper (freshly cracked)
  • 1 tablespoon Fresh Flat-Leaf Parsley (finely chopped)
  • 1 pinch Red Chili Flakes (optional, for subtle heat)
  • 1 tablespoon Parmigiano-Reggiano (freshly grated)

👨‍🍳 Instructions

  1. 1

    Clean the mushrooms using a damp paper towel to remove any grit; avoid washing them under water as they act like sponges and will become soggy.

  2. 2

    Slice the mushrooms into uniform 1/4-inch thick pieces to ensure even cooking and a consistent mouthfeel.

  3. 3

    Heat a large wide-based skillet over medium-high heat. Add the olive oil and 1 tablespoon of the butter, swirling until the butter foam subsides.

  4. 4

    Add the mushrooms to the pan in a single layer. Do not crowd the pan; if necessary, cook in two batches to ensure they sear rather than steam.

  5. 5

    Leave the mushrooms untouched for 3-4 minutes until the bottom sides are deeply browned and caramelized.

  6. 6

    Toss the mushrooms and continue to cook for another 3 minutes. Season with a pinch of salt and cracked pepper only after they have browned.

  7. 7

    Reduce the heat to medium. Add the remaining tablespoon of butter, the sliced garlic, and the fresh thyme leaves.

  8. 8

    Sauté for 1-2 minutes until the garlic is fragrant and golden, being careful not to let it burn.

  9. 9

    Deglaze the pan with the balsamic vinegar and lemon juice, scraping up any flavorful browned bits (fond) from the bottom of the skillet.

  10. 10

    While the mushrooms finish, toast your sourdough slices until the edges are golden brown but the center remains slightly chewy.

  11. 11

    Spread a generous layer of mascarpone cheese over each slice of warm toast.

  12. 12

    Pile the hot garlic mushrooms high onto the prepared toast slices.

  13. 13

    Garnish with chopped parsley, a sprinkle of chili flakes, a dusting of Parmigiano-Reggiano, and a final hit of flaky sea salt.

💡 Chef's Tips

Don't salt the mushrooms too early; salt draws out moisture which prevents the browning you need for deep flavor. Use a variety of mushrooms like Shiitake for earthiness and Oyster for a silky texture. If the pan looks too dry, add a splash of vegetable stock or white wine instead of more oil. Ensure your garlic is fresh; old garlic can turn bitter when fried. Rub a raw garlic clove over the toasted bread before spreading the cheese for an extra punch of flavor.

🍽️ Serving Suggestions

Pair with a perfectly poached egg on top for an oozing, rich yolk sauce. Serve alongside a crisp arugula salad with a light lemon vinaigrette to cut through the richness. A fresh cup of Earl Grey tea or a bold Espresso balances the earthy tones beautifully. For a brunch cocktail, a spicy Bloody Mary is the ultimate savory companion. Add a few slices of avocado on the side for added creaminess and healthy fats.
