Ingredients

  • 1 cup pearl barley, rinsed
  • 2 ½ cups vegetable broth (low sodium preferred)
  • 1 tablespoon olive oil
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 2 medium carrots, diced
  • 1 red bell pepper, diced
  • 1 zucchini, diced
  • 1 cup mushrooms, sliced
  • 1 cup fresh spinach, roughly chopped
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • Salt and pepper, to taste
  • ½ cup shredded mozzarella or vegan cheese (optional)
  • Fresh parsley, chopped for garnish

Equipment

  • Medium saucepan with lid
  • Large sauté pan or skillet
  • 9×9 inch baking dish or similar casserole dish
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Knife and cutting board

Instructions

  1. Cook the barley: In a medium saucepan, combine the rinsed barley and vegetable broth. Bring to a boil, then reduce heat to low, cover, and simmer for about 30-35 minutes or until barley is tender and liquid is absorbed. Remove from heat and fluff with a fork.
  2. Prepare the vegetables: While the barley cooks, heat olive oil in a large sauté pan over medium heat. Add onion and garlic, cooking until fragrant and translucent, about 3-4 minutes.
  3. Sauté the veggies: Add carrots, bell pepper, zucchini, and mushrooms. Cook for 7-8 minutes, stirring occasionally, until vegetables are tender but still vibrant. Stir in dried thyme and oregano, seasoning with salt and pepper to taste.
  4. Add spinach: Toss in the chopped spinach and cook for another 2 minutes until wilted.
  5. Combine barley and veggies: Transfer the cooked barley to the sauté pan with vegetables. Mix thoroughly to combine all ingredients evenly.
  6. Assemble the casserole: Preheat your oven to 375°F (190°C). Lightly grease the baking dish. Pour the barley and vegetable mixture into the dish and spread evenly.
  7. Add cheese topping (optional): Sprinkle the shredded mozzarella or vegan cheese evenly over the top for a gooey finish.
  8. Bake: Place the casserole in the oven and bake for 20-25 minutes, or until the cheese is melted and slightly golden.
  9. Garnish and serve: Remove from oven, sprinkle with fresh parsley, and let cool slightly before serving.

Tips & Variations

“Feel free to swap the vegetables based on what’s in season or what you have in your fridge. Sweet potatoes, kale, or peas would be excellent additions!”

  • Make it vegan: Simply omit the cheese or use a plant-based alternative for a dairy-free version.
  • Boost the protein: Add cooked lentils or chickpeas for extra protein and texture.
  • Spice it up: Incorporate a pinch of smoked paprika or chili flakes for a subtle kick.
  • Make ahead: Prepare the casserole a day in advance and refrigerate. Bake when ready to serve.
  • Use pearl or hulled barley: Pearl barley cooks faster, but hulled barley is more nutritious though takes longer to cook.
