Instructions

  1. Preheat oven to 400°F. Wash and dice potatoes into 1-inch cubes. Place in a pot with salted water, bring to a boil and cook until tender, about 15 minutes.
  2. While potatoes cook, trim asparagus and cut into 2-inch pieces. Slice portobello mushrooms into 1/2-inch strips. Finely chop chives.
  3. On a baking sheet, toss asparagus with a drizzle of oil, salt and pepper. Roast for 10-12 minutes until tender. In the last 3 minutes, sprinkle sliced almonds on top and toast lightly.
  4. Drain potatoes and return to pot. Add sour cream, crème fraîche, truffle seasoning and salt to taste. Mash until smooth and creamy. Cover to keep warm.
  5. Heat a skillet over medium-high heat with a drizzle of oil. Add portobello strips and cook without stirring for 3-4 minutes until browned. Flip and cook another 2 minutes. Add mushroom stock concentrate and 1/4 cup water, scraping up any browned bits. Simmer until sauce thickens slightly, about 1 minute.
  6. Slice demi-baguette in half lengthwise, then cut each half crosswise to make 4 pieces. Toast in oven or toaster until golden. Spread each with ricotta, drizzle with hot honey and sprinkle with chopped walnuts and chives.
  7. Serve truffle mash alongside portobello mushrooms and asparagus amandine. Garnish with additional chives if desired. For dessert, enjoy vanilla cheesecake.

Recipe Tips

For extra creamy mash, warm the sour cream and crème fraîche before adding.

Don’t overcrowd the skillet when cooking mushrooms; work in batches if needed for better browning.

Toast the almonds just until fragrant to avoid burning.

FAQ

Can I use regular honey instead of hot honey?

Yes, regular honey works well. For a spicy kick, add a pinch of red pepper flakes.

What can I substitute for truffle seasoning?

You can use a pinch of truffle salt or omit it for a classic mashed potato flavor.

How do I store leftovers?

Store components separately in airtight containers in the refrigerator for up to 3 days. Reheat gently.
