Porcini risotto with cooked Boletus edulis pieces and Parmigiano Reggiano

Porcini Risotto with Dried Boletus edulis

August 27, 2026Rostislav Savov0 comments

This four-serving risotto uses 25 g dried porcini and 320 g risotto rice. The mushrooms soak in warm water, are drained and rinsed, then cook with the rice through measured additions of hot fresh stock. The recipe discards the soaking liquid to keep sediment control simple.

Quick Answer

Porcini risotto with dried Boletus edulis begins by soaking 25 g porcini for 20–30 minutes, draining and rinsing the pieces. Cook shallot and porcini, toast 320 g rice, then add 1 litre hot unsalted stock gradually over 18–20 minutes. Finish off the heat with butter and Parmigiano Reggiano.

Ingredients

  • 25 g dried Boletus edulis porcini
  • Warm water, for rehydration; soaking liquid discarded in this formula
  • 1 litre unsalted vegetable or chicken stock, kept hot
  • 15 ml extra-virgin olive oil
  • 30 g unsalted butter, divided
  • 60 g shallot, finely chopped
  • 320 g Carnaroli or Arborio rice
  • 60 g Parmigiano Reggiano, finely grated
  • 3 g fine salt, plus more only after tasting
  • 0.5 g finely ground black pepper
  • 10 g flat-leaf parsley, finely chopped

The risotto contains milk. Stock may contain celery or other declared allergens. Check the rice, stock, butter and cheese labels for current declarations and cross-contact.

Equipment

  • Clean soaking bowl and fine strainer
  • Small saucepan for hot stock
  • Wide heavy-based sauté pan
  • Ladle and heatproof spoon
  • Digital scale and measuring jug
  • Knife and board

Before You Start

Read the physical label and current Terra Ross dried-porcini page. This formula discards the soaking liquid rather than depending on filtration. It uses fresh unsalted stock for predictable sediment and salt control.

Keep the stock hot but not violently boiling. Measure the rice, divide the butter into 15 g for cooking and 15 g for finishing, and grate the cheese before the rice enters the pan.

Method

  1. Rehydrate the porcini

    Cover 25 g dried porcini with warm water and soak for 20–30 minutes, targeting 25 minutes within the product window.

  2. Drain, rinse and cut

    Lift without disturbing sediment, discard the liquid, rinse carefully and cut large pieces.

  3. Heat the stock

    Bring 1 litre unsalted stock to a gentle simmer and keep it hot.

  4. Soften the shallot

    Heat 15 ml oil and 15 g butter; cook 60 g shallot for 4–5 minutes without browning.

  5. Cook the porcini

    Add the drained porcini and cook for 3 minutes, stirring for even heating.

  6. Toast the rice

    Add 320 g rice and stir for 2 minutes until hot and lightly coated.

  7. Add stock gradually

    Add hot stock one ladle at a time over 18–20 minutes, maintaining a steady simmer.

  8. Adjust the final consistency

    Stop when rice is tender with a slight bite and flows softly; do not force in unused stock.

  9. Finish off the heat

    Remove from heat; stir in 15 g butter and 60 g Parmigiano Reggiano, rest 2 minutes and add parsley.

  10. Season and serve

    Add 3 g salt and 0.5 g pepper, taste, adjust sparingly and divide among four warm bowls.

Control Risotto Texture

Use a wide pan so grains cook in a relatively even layer. Stock should enter hot enough to preserve the simmer. Add it in measured portions and allow the rice to absorb most of one addition before the next.

The final risotto should spread gently rather than sit as a stiff mound. Butter and cheese thicken it during the off-heat finish, so stop the stove phase slightly looser than the intended plate texture. If the pan becomes dry before the rice is tender, add more hot stock in small amounts.

Food Safety and Allergen Notes

Rehydration does not complete cooking. The porcini first cook with the shallot and then remain in the pan throughout the 18–20 minute rice stage. Use clean water for rinsing and do not include unresolved sediment.

Milk is present in butter and Parmigiano Reggiano. Check stock for celery and any other allergens. Serve risotto promptly. If leftovers are unavoidable, refrigerate within two hours and reheat thoroughly to 74°C / 165°F. As conservative rice-quality guidance, use the chilled risotto promptly and follow current official or local food-safety rules for its refrigerated storage duration. Do not cool a deep pot slowly at room temperature.

Variations Within the Recipe Intent

Vegetable or chicken stock can be used when its label suits the diner. Carnaroli and Arborio behave differently, so judge texture rather than assuming identical absorption. Parsley may be omitted. Do not add truffle oil to make the dish “more porcini”; porcini and truffles remain distinct.

A liquid-reuse variation would require a separate controlled formula because filtration, stock quantity and seasoning would all change. This version intentionally avoids that dependency.

Common Mistakes

Mistake Better action
Using gritty soaking liquid Discard it in this formula and use fresh stock.
Adding cold stock Keep stock hot to preserve the simmer.
Flooding the rice Add one ladle at a time.
Finishing over high heat Stir butter and cheese in off the heat.
Letting risotto stand Serve immediately in warm bowls.

Scaling and Timing the Risotto

Risotto is sensitive to pan width and batch depth. For eight servings, use two wide pans or a vessel proven to keep an even simmer; simply doubling ingredients in a small pan changes evaporation and stirring.

Keep extra hot stock available when testing a larger batch, but do not pour it in automatically. Rice variety, pan and heat determine actual absorption. The endpoint remains tender rice with a slight central bite and enough surrounding liquid to flow.

Coordinate service before the first ladle enters the rice. Warm bowls, grate cheese and prepare garnishes in advance. Once butter and Parmigiano are folded in, the risotto should rest only for the stated two minutes, receive final seasoning and go directly to the table.

Why the Risotto Formula Uses Fresh Stock

Fresh unsalted stock gives the cook a known liquid volume without depending on the clarity or concentration of porcini soaking water. It also makes the recipe easier to repeat across batches of dried mushrooms with different sediment levels.

Olive oil and the first butter portion carry the shallot and porcini through the aromatic stage. The second butter portion and Parmigiano enter off the heat, where they support a glossy finish without extending stove cooking. Parsley is optional and should remain a light fresh accent.

Measure the dry rice and porcini by weight. Keep stock in a marked jug or saucepan so additions can be monitored without forcing the entire litre into the pan. This approach separates the recipe’s fixed quantities from its texture-based endpoint and makes any unused stock an expected control rather than an error.

Frequently Asked Questions

Can the porcini soaking liquid be used?

This formula discards it and uses fresh stock for simple sediment control.

Why rinse the porcini after soaking?

Rinsing removes remaining natural particles from the softened pieces.

Which rice should I use?

Carnaroli or Arborio works; judge texture because absorption differs.

Should rice be rinsed?

No. This formula toasts the dry rice so its surface starch can support the risotto texture.

Can I add all stock at once?

No. Gradual additions provide better control over absorption and texture.

Is wine required?

No. This formula uses stock without wine.

Can the recipe be dairy-free?

Not by simple omission; butter and Parmigiano define the finish, so a separate formula is needed.

Are porcini a type of truffle?

No. Boletus edulis is a wild mushroom.

How should leftovers be handled?

Chill within two hours, use promptly as conservative rice-quality guidance, follow current official or local storage rules and reheat thoroughly to 74°C / 165°F.

Can the recipe be doubled?

Use a sufficiently wide pan or cook separate batches; pan geometry affects evaporation and rice cooking.

Sources and Further Reading

Conclusion

Controlled rehydration, careful rinsing, hot stock and gradual absorption give dried porcini a clear place in risotto. Finish away from heat and serve immediately while the rice remains fluid. The measured dry weight and fresh-stock method keep the result repeatable without relying on uncertain soaking liquid. Warm bowls before the final off-heat finish and portion the rice at once. That short service discipline preserves the intended flowing consistency instead of allowing a correctly cooked risotto to tighten while it waits.
