THE METHOD
1

Heat oil in a large pot over medium-high heat. Add the sliced mushrooms and cook undisturbed for 4 minutes until browned on one side, then stir and cook 3 more minutes. Remove and set aside.

2

Add onion, carrot, and celery to the same pot. Cook over medium heat 6 minutes until softened.

3

Add garlic and thyme. Cook 1 minute.

4

Return mushrooms to the pot. Add soy sauce and stir to combine.

5

Add the broth and water. Bring to a boil.

6

Add the barley. Reduce heat to a steady simmer and cook uncovered 40 minutes, stirring occasionally, until barley is tender.

7

Taste and adjust salt and pepper. The soup will thicken considerably as it sits. Add water when reheating.

When the math doesn't work

PC cremini mushrooms 454g at $4.99 are the most expensive ingredient here. They are worth it — mushrooms release a lot of water and flavor into the broth. White button mushrooms at the same price would work.

  • Soy sauce adds a background savory note without tasting Asian. It is common in European mushroom soups. Do not skip it.
  • This soup is better the next day. The barley keeps absorbing liquid; add water when reheating.

Gluten-Free

This recipe can be made gluten-free with substitutions.

  • Replace pearl barley with long-grain white rice (same weight) (Rice is GF and slightly cheaper. Add 20 minutes before the end.)
  • Replace soy sauce with tamari (Same cost, gluten-free.)

Barley and standard soy sauce both contain gluten. Use rice and tamari for a fully GF version.
