Ingredients You’ll Need

1 cup pearl barley, uncooked, rinsed: Pearl barley provides the chewy, hearty base and soaks up dressing for substantial texture.
3 cups water: Water is used to cook the barley to tender-chewy doneness.
12 Brussels sprouts, trimmed (and cut into halves if they’re large): Brussels sprouts caramelize at high heat and add a nutty, slightly crisp bite; halve large ones so they cook evenly.
2 large carrots, peeled and sliced: Carrots add sweetness and a firmer texture that holds up under roasting when sliced.
1 small-medium sweet potato, peeled & diced: Sweet potato contributes natural sweetness and a soft, creamy contrast when diced.
2-3 medium beets, peeled & cut up: Beets bring earthy sweetness and deep color; they’re dense so cutting them small helps them roast in time with other veg.
4 medium tomatoes, quartered: Tomatoes add juiciness and bright acidity to finish the salad; quartering them keeps the pieces bite-sized.
3-4 tablespoons olive oil: Olive oil helps vegetables brown and prevents sticking; it’s the roasting fat that carries flavor.
1 teaspoon garlic powder, or to taste: Garlic powder layers savory garlic flavor across the vegetables without adding moisture.
5 dashes Italian seasoning, or to taste: Italian seasoning adds a herby background note that complements the roasted vegetables.
Salt & pepper, to taste: Salt and pepper are used to season vegetables and the final salad to taste.
Handful spinach, optional: A handful of spinach is optional for a leafy element and extra greens if you prefer the salad dressed over fresh leaves.
3 heaping tablespoons tahini: Tahini is the creamy, nutty base of the dressing that gives body and richness.
1/2 lemon, juice of: Fresh lemon juice brightens and thins the tahini while adding essential acidity.
1 clove garlic, minced: Fresh minced garlic adds sharp, aromatic lift to the dressing.
1 tablespoon pure maple syrup: Pure maple syrup balances the dressing with a touch of sweetness to round the lemon and tahini.
Salt & pepper, to taste: Additional salt and pepper let you finish the dressing and seasoned barley/veg to taste.
3-4 tbsp water, to thin the dressing: A few tablespoons of water are used to thin the tahini into a pourable dressing that coats the barley and vegetables.

How to Make the Salad

Cook the pearl barley according to package directions. For example, cook 1 cup pearl barley in 3 cups water with a pinch of salt — this typically takes about 30 minutes — and aim for a chewy but tender texture (not mushy). Drain any excess and fluff with a fork.
Preheat the oven to 400F and position the rack in the middle. This higher temperature encourages caramelization on the vegetables’ edges.
Cut the vegetables into pieces about 1″ so they cook evenly. Toss the Brussels sprouts, carrots, sweet potato, beets, and tomatoes with the 3-4 tablespoons olive oil, 1 teaspoon garlic powder (or to taste), 5 dashes Italian seasoning (or to taste), and salt & pepper. Spread them in a single layer on a baking sheet so pieces have space to brown rather than steam.

Roasting for Caramelization

High, dry heat is what creates the deeply flavored, browned edges on the vegetables. That caramelization is key to turning simple root vegetables into something savory and almost sweet.

Keep the oven at 400F and arrange vegetables in a single layer on the middle rack. If pieces are touching too much they’ll steam instead of roast.

Don’t crowd the pan — leave space between pieces.
Use a rimmed sheet to catch any juices; flip vegetables once midway for even color.
Roast until edges are golden and centers are tender — timing depends on size but generally 25–35 minutes for 1″ pieces.

Cooking Barley Perfectly

Pearl barley needs a bit more time than quick grains but rewards you with a nutty chew that stands up to roasted veg and dressing.

Follow your package instructions, but use the example ratio (1 cup barley to 3 cups water) as a reliable baseline and plan for roughly 30 minutes of simmering.

Bring to a simmer, then cover and cook gently until grains are tender yet slightly chewy.
If water is absorbed but barley is still firm, add a splash more water and continue cooking a few minutes.
Fluff with a fork before combining so the dressing can cling to individual grains.

Tahini Dressing Tips

Tahini thickens on its own, so start with the full flavor components (tahini, lemon, garlic, maple) then thin gradually with water until the dressing pours easily.

Taste as you thin — a little extra lemon brightens it, while a touch more maple mellows acidity if needed.

3 heaping tablespoons tahini + juice of 1/2 lemon + 1 clove garlic + 1 tablespoon maple syrup is the base.
Thin with 3-4 tbsp water, adding a tablespoon at a time to reach desired consistency.
Store extra dressing in the fridge; it may thicken and can be loosened with warm water or more lemon before using.

Quick Tips

Pan spacing: Use a large rimmed baking sheet and don’t overcrowd it — vegetables need room to brown. Roast in two batches if necessary.

Beet timing: Because beets are dense, cut them smaller than other vegetables or start them on the sheet a little earlier so everything finishes around the same time.

Barley texture: Taste the barley near the minimum package time; it should be tender with a slight chew. If it’s still too firm, continue simmering and check every 5 minutes.

Dressing consistency: Whisk 3 heaping tablespoons tahini with the juice of 1/2 lemon, 1 clove minced garlic, 1 tablespoon maple syrup, and salt & pepper. Thin with 3-4 tbsp water until pourable, then adjust lemon and salt to taste.

Frequently Asked Questions

Yes. Serve it warm right after roasting and tossing with barley and dressing for a cozy main, or chill it and serve cold for lunches — both work well because the barley holds its texture.

Chickpeas (roasted or plain), crumbled feta, or sliced grilled chicken are all good choices to make this salad more filling while keeping the flavors balanced.

Yes — farro, brown rice, or the wild rice salad linked above are suitable alternatives, though cooking times and textures will vary.

Final Thoughts

This recipe is built for flexibility: adjust the vegetables to what’s in season, roast for deeper color, and tweak the dressing thickness to coat the barley and veg without drowning them.

Leftovers keep well refrigerated for 3–4 days; reheat gently if you prefer the salad warm or enjoy cold straight from the fridge.
