Steps
Before you start
- Measure out your rice and broth before starting
- Use a heavy-bottomed pot with a tight-fitting lid for even cooking
- Have all ingredients prepped and within arm's reach
Sauté mushrooms until golden
- Heat the olive oil in a large heavy-bottomed pot (3–4 quart) over medium-high heat for 1 minute.
- Add the sliced mushrooms in a single layer, season with ¼ teaspoon of the salt, and let them cook without stirring for 2–3 minutes until the bottoms are golden brown.
- Stir and cook for another 4–5 minutes, stirring occasionally, until all the mushrooms are tender and any released liquid has mostly evaporated.
- They should be deeply browned and fragrant.

Ready when: Mushrooms are golden brown and have released and reabsorbed their liquid
Tip: Don't stir the mushrooms too early—letting them sit allows them to develop a caramelized crust
Add garlic and pepper
- Add the minced garlic and cracked black pepper to the mushrooms and stir constantly for about 30 seconds until fragrant.
- Be careful not to let the garlic burn.

Ready when: Garlic is fragrant and releases its aroma
Toast the rice
- Add the rinsed brown rice to the pot and stir constantly for 2–3 minutes.
- The rice will begin to dry out and smell slightly nutty as the grains warm and any remaining moisture evaporates.
- This toasting step deepens the rice's flavor.

Ready when: Rice is warm and has a subtle nutty aroma
Add broth and bring to boil
- Pour in the vegetable broth and remaining ½ teaspoon salt.
- Stir once or twice to combine, then bring to a boil over medium-high heat, about 2–3 minutes.
- Watch for steam and bubbling around the edges.

Ready when: Liquid is at a rolling boil
Reduce heat and cover
- Once the liquid is boiling, reduce the heat to low, stir the rice once, and cover the pot with a tight-fitting lid.
- The rice will now simmer gently and steam as it cooks.

Tip: A tight lid is essential—steam trapped inside will cook the rice evenly
Simmer until rice is tender
- Let the rice simmer gently for 40 minutes without lifting the lid.
- Brown rice takes longer than white rice to soften.
- After 40 minutes, peek under the lid to check: the rice should be tender but still have a slight firmness to the bite, and most of the liquid should be absorbed.

Ready when: Rice is tender, liquid is mostly absorbed, and grains are separate
Tip: Avoid lifting the lid during cooking—each peek releases steam and slows cooking
Rest and fluff
- Remove the pot from heat and let it sit covered for 10 minutes.
- This allows the rice to finish absorbing any remaining moisture.
- After resting, remove the lid and gently fluff the rice with a wooden spoon or rice paddle, breaking up any clumps.
- If desired, stir in the optional butter for extra richness.

Ready when: Rice is fluffy, grains are separated, and all liquid is absorbed
Tip: Fluffing with a gentle hand prevents breaking the grains and makes the rice light and airy

Tips
- For the best texture, use long-grain brown rice rather than short-grain, which tends to stick together
- If your mushrooms release a lot of liquid, drain it off before proceeding—you want them to caramelize, not steam
- Cracking peppercorns fresh in a mortar and pestle or with the side of a knife gives more texture and flavor than pre-ground pepper
- This pilaf pairs beautifully with roasted chicken, grilled steak, or a simple salad for a vegetarian meal
Make ahead
Prepare the mushrooms and garlic up to 2 hours ahead, but keep them separate and at room temperature. Cook the full dish no more than 1 day in advance; reheat gently with a splash of broth if needed.
Storage & reheating
Store in an airtight container in the refrigerator for up to 4 days. To reheat, add 2–3 tablespoons of broth or water per cup of rice and warm gently on the stovetop over medium-low heat for 3–5 minutes, stirring occasionally, until heated through. You can also microwave individual portions, covered, for 1–2 minutes with a splash of broth. The dish does not freeze well due to the texture change in the rice.
Substitutions
- cremini or button mushrooms → cremini and shiitake mushroom blend (half of each), or portobello mushrooms, diced. Shiitake adds deeper umami and woodsy notes; portobello gives a meatier texture
- long-grain brown rice → long-grain white rice or jasmine rice. Reduce the broth to 2.5 cups and cooking time to 18–20 minutes for white rice
- vegetable broth or low-sodium chicken broth → mushroom broth or beef broth. Mushroom broth doubles down on umami; beef broth adds richness
- black pepper → white pepper or a blend of peppercorns (black, pink, and coriander). White pepper is milder and won't be visible; mixed peppercorns add complexity
