Why You’ll Love This Hearty Mushroom Barley Pilaf Side Dish
- Comforting and filling: Barley has a pleasantly chewy texture that makes this side dish feel substantial.
- Simple ingredients: Vegetable stock, barley, mushrooms, scallions, celery, salt, and pepper are all you need.
- Easy to prepare: The barley simmers while you cook the vegetables, so the tasks overlap.
- Dairy-free by design: The recipe uses stock instead of butter or cream. Just check the stock label to confirm it suits your needs.
- Good warm or chilled: Serve it right after cooking, or cool it for a convenient make-ahead dish.
Mushroom Tips
Choose mushrooms that feel firm and look dry, with no slimy spots or strong odor. White button and cremini mushrooms both work well here; cremini have a slightly deeper flavor. Wipe them with a damp paper towel or brush off any dirt, then slice them evenly so they cook at a similar pace. Avoid crowding the skillet, since mushrooms release moisture as they cook. Give that liquid time to evaporate so the vegetables become savory rather than watery.
Options for Substitutions
- Use another stock: Low-sodium vegetable stock is a good choice if you want more control over the salt. You can also use mushroom stock for a deeper earthy flavor.
- Switch the barley: Hulled and pot barley both work. Hulled barley may take longer to soften, so follow the package guidance and check it as it cooks.
- Try another mushroom: Cremini, white button, or a mix of mushrooms can be used in the same amount. Shiitake mushrooms also add a strong savory note, though their stems are usually best removed.
- Replace the scallions: Use a small chopped onion or a few tablespoons of chopped shallot instead. Cook until softened before adding the mushrooms.
- Change the celery: If you do not have celery, use a little diced carrot or bell pepper. The flavor will change, but the pilaf will still be tasty.
- Adjust the seasoning: Add dried thyme or parsley for extra aroma, or use a pinch of garlic powder. If your stock is salty, start with less salt and taste before serving.
Watch Out for These Mistakes
First, do not assume every type of barley cooks in exactly 50 minutes. Hulled barley often takes longer than pot barley, so check the package and taste a few grains near the end. The barley should be tender but still pleasantly chewy.
Next, keep the pan covered while the barley simmers, and use low heat once the stock boils. If the heat is too high, the liquid may evaporate before the barley softens. If the grains are still firm, add a little hot water and continue cooking.
Also, drain the barley well before combining it with the vegetables. Excess liquid can make the pilaf wet and dilute its flavor. Meanwhile, let most of the mushroom liquid cook away before you stir the vegetables into the barley.
Finally, season thoughtfully. Vegetable stock can contain a lot of salt, so taste the finished pilaf before adding more. Add the mushrooms only after the scallions and celery have started to soften, so the vegetables cook evenly.
What to Serve With Hearty Mushroom Barley Pilaf Side Dish?
This Hearty Mushroom Barley Pilaf Side Dish pairs nicely with roasted chicken, baked salmon, or pan-seared tofu. For a plant-based meal, serve it with roasted carrots or green beans and a crisp leafy salad. You can also add a bowl of vegetable soup for a cozy, satisfying dinner. Since the pilaf has an earthy flavor, simple sides with fresh or lightly seasoned flavors balance the plate well.
Storage Instructions
Store: Let the pilaf cool, then place it in an airtight container and refrigerate it within two hours of cooking. Enjoy it within 3 to 4 days. For best texture, store it in a shallow container so it cools quickly.
Freeze: Transfer cooled pilaf to a freezer-safe container or bag, leaving a little room for expansion. Freeze for up to 2 months for the best quality. Thaw it overnight in the refrigerator before reheating.
Reheat: On the stovetop, warm the pilaf in a covered skillet over low heat with a splash of water or vegetable stock. Stir now and then until hot throughout. In the microwave, place a serving in a microwave-safe dish, add a small splash of liquid, cover loosely, and heat in short intervals, stirring between each one.

Step-by-Step Instructions
Step 1: Set Aside Stock and Bring It to a Boil
Measure out 3 tablespoons of the vegetable stock and set it aside for the vegetables. Pour the remaining stock into a medium saucepan and bring it to a boil over high heat.

Add the barley to the boiling stock. Lower the heat, cover the pan, and simmer for about 50 minutes, or until the barley is tender. Check the package directions, especially if you are using hulled barley, since it may need more time.
Step 3: Drain the Cooked Barley
When the barley is tender, drain off any extra liquid. Then transfer the barley to a large bowl and set it aside while you cook the vegetables.
Step 4: Cook the Scallions and Celery
While the barley cooks, warm the reserved stock in a medium skillet over medium heat. Add the chopped scallions and celery. Cook for 5 to 6 minutes, stirring now and then, until the celery is crisp-tender.
Step 5: Add the Mushrooms and Seasoning
Stir in the sliced mushrooms, salt, and pepper. Cook for about 5 minutes, stirring as needed, until the vegetables are soft and most of the mushroom liquid has evaporated.
Step 6: Combine and Serve
Add the cooked vegetables to the bowl of barley and stir until evenly mixed. Taste and adjust the seasoning if needed. Serve the pilaf warm, or cool it and serve chilled.
