Tools You'll Need

  • Measuring cups and spoons
  • Whisk or fork

Ingredients

For the Grains:

  • 1 cup quinoa, farro, or brown rice
  • 2 cups water or vegetable broth
  • ¼ teaspoon salt

For the Roasted Vegetables:

  • 2 cups sweet potatoes, peeled and cubed (about 1 large)
  • 2 cups Brussels sprouts, trimmed and halved
  • 1 red onion, cut into wedges
  • 2 tablespoons olive oil
  • 1 tablespoon balsamic vinegar
  • 1 teaspoon dried rosemary
  • 1 teaspoon dried thyme
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

For the Tahini Dressing:

  • ¼ cup tahini
  • 2 tablespoons lemon juice
  • 2 tablespoons water (plus more to thin)
  • 1 tablespoon olive oil
  • 1 clove garlic, minced
  • ¼ teaspoon salt
  • Pinch of cumin (optional)

For Assembly:

  • 1 avocado, sliced
  • 2 cups fresh spinach or mixed greens
  • ¼ cup pumpkin seeds or toasted almonds
  • Fresh parsley or cilantro, chopped
  • Optional: crumbled feta or goat cheese

Instructions

Cook the Grains:

  1. Rinse quinoa (or your chosen grain) thoroughly in a fine-mesh strainer. In a medium saucepan, combine grains, water (or broth), and salt. Bring to a boil, then reduce heat to low, cover, and simmer according to package directions (about 15 minutes for quinoa, 25-30 for farro, 35-40 for brown rice). Remove from heat and let stand covered for 5-10 minutes. Fluff with a fork.

Roast the Vegetables:

  1. Preheat oven: Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper.
  2. Prep vegetables: In a large bowl, combine sweet potatoes, Brussels sprouts, and red onion. Drizzle with olive oil and balsamic vinegar, then sprinkle with rosemary, thyme, salt, and pepper. Toss until well coated.
  3. Roast: Spread vegetables in a single layer on the prepared baking sheet. Roast for 20-25 minutes, flipping halfway through, until tender and caramelized on the edges.

Make the Tahini Dressing:

  1. While vegetables roast, prepare the dressing. In a small bowl or jar, whisk together tahini, lemon juice, water, olive oil, minced garlic, salt, and cumin (if using). Whisk until smooth. Add more water a tablespoon at a time until you reach your desired consistency – it should be pourable but still creamy.

Assemble the Bowls:

  1. Divide the cooked grains among 4 bowls.
  2. Add a handful of fresh spinach or mixed greens to each bowl.
  3. Top with the roasted vegetables and sliced avocado.
  4. Drizzle generously with tahini dressing.
  5. Sprinkle with pumpkin seeds and fresh herbs. Add crumbled feta if desired.
  6. Serve immediately or store for meal prep (see notes).

Pro Tips

  • Cut vegetables uniformly: Chop sweet potatoes and Brussels sprouts into similar-sized pieces for even roasting.
  • Don't overcrowd the pan: Give vegetables space to roast rather than steam. Use two baking sheets if needed.
  • Make extra dressing: This tahini dressing keeps well for a week and is delicious on everything – salads, grain bowls, roasted veggies, etc.
  • Meal prep magic: Store components separately in airtight containers. Assemble just before eating to keep greens fresh and avocado from browning.
  • Warm it up: For meal prep bowls, reheat the grains and vegetables, then add fresh greens, avocado, and dressing after reheating.

Recipe Variations

  • Add Protein: Top with grilled chicken, salmon, chickpeas, or tofu.
  • Mediterranean Style: Add cucumber, cherry tomatoes, olives, and feta; use lemon-oregano dressing.
  • Southwest Bowls: Use black beans, corn, bell peppers, and cilantro-lime dressing.
  • Asian-Inspired: Add edamame, carrots, and sesame seeds; use ginger-sesame dressing.
  • Different Grains: Try farro, freekeh, barley, or cauliflower rice for low-carb.
  • Seasonal Veggies: Use whatever's in season – butternut squash in fall, asparagus in spring, zucchini in summer.
  • Vegan: This recipe is easily vegan – just skip the feta or use vegan cheese.

FAQs

How long do roasted veggie grain bowls last in the fridge?
Stored separately in airtight containers, the components will keep for 4-5 days. Assemble just before serving for best results.

Can I freeze these bowls?
You can freeze the cooked grains and roasted vegetables for up to 3 months. Thaw and reheat, then add fresh toppings. Don't freeze the greens, avocado, or dressing.

What's the best grain for grain bowls?
Quinoa, farro, brown rice, and barley are all excellent. Quinoa cooks quickly and is protein-rich; farro has a wonderful chewy texture.

How do I reheat the components?
Reheat grains and vegetables in the microwave or in a skillet with a splash of water. Add fresh greens, avocado, and dressing after reheating.

Can I make this gluten-free?
Yes! Use quinoa, brown rice, or certified gluten-free grains. All other ingredients are naturally gluten-free.

How do I prevent avocado from browning in meal prep?
Store avocado whole and slice fresh each day, or toss sliced avocado with lime juice and store in an airtight container with the pit.

What other dressings work well?
Lemon vinaigrette, balsamic glaze, green goddess, or simple olive oil and lemon juice are all delicious options.
