Ingredients
- 1 cup pearl barley, rinsed
- 2 cups vegetable broth
- 1 tablespoon olive oil
- 3 cups mixed mushrooms (cremini, shiitake, oyster), cleaned and sliced
- 1 medium yellow onion, finely chopped
- 3 cloves garlic, minced
- 1 large carrot, diced
- 1 teaspoon fresh thyme, finely chopped
- 1/2 cup grated Parmesan cheese (optional, omit for vegan)
- 2 tablespoons all-purpose flour
- 1 ½ cups milk (use plant-based milk for dairy-free)
- Salt and freshly cracked black pepper, to taste
- 2 tablespoons fresh parsley, chopped, for garnish
- 1 tablespoon vegan butter or unsalted butter
Instructions
- Prepare the barley: In a medium saucepan, combine rinsed barley and vegetable broth. Bring to a boil, then reduce heat to low. Simmer uncovered for 30-35 minutes, until tender but still slightly chewy. Drain any excess liquid. Tip: Keep an eye on the barley to avoid overcooking-it should hold its shape without becoming mushy.
- Sauté the mushrooms: While the barley cooks, heat olive oil in a large skillet over medium-high heat. Add mushrooms and a pinch of salt, stirring occasionally, until they release moisture and turn golden brown, about 7-8 minutes. Set aside.
- Cook aromatics: In the same skillet, add butter, then sauté onions, garlic, and diced carrots over medium heat until softened and fragrant, about 5 minutes. Stir in fresh thyme.
- Make the creamy sauce: Sprinkle flour over the softened vegetables and stir thoroughly to coat. Slowly whisk in the milk, ensuring there are no lumps. Continue to cook and stir until sauce thickens, about 5 minutes. Season with salt and pepper.
- Combine and assemble: Fold cooked barley and sautéed mushrooms into the creamy sauce. Mix until evenly distributed and gently heated through.
- Transfer to casserole dish: Spoon the mixture into a greased 9×13-inch baking dish. Sprinkle the top evenly with grated Parmesan if using.
- bake and finish: Bake uncovered in a preheated oven at 375°F (190°C) for 15-20 minutes until bubbly and golden on top. Remove and let rest for 5 minutes before serving.
Tips for Success
- Barley cooking Precision: Opt for pearl barley for a quicker cooking time and tender bite. If using hulled barley, increase cooking time and liquid slightly. Always rinse thoroughly to remove excess starch and prevent clumping.
- Mushroom Mix: Choosing a combination of mushrooms ensures maximum depth and texture-cremini bring earthiness,shiitake adds smoky notes,and oyster mushrooms introduce a delicate,velvety feel.
- Customize the Creaminess: For a dairy-free version, swap milk and butter for almond or oat milk and vegan butter. Nutritional yeast can be sprinkled on top for a cheesy flavor without dairy.
- Make Ahead: Prepare the barley and mushroom mixture a day before, then refrigerate. bake just before serving to enhance flavors and ease last-minute cooking.
- Texture Balance: Avoid overloading with liquid; the casserole should be moist but not soupy. The creamy sauce gently clings to the grains, creating a luscious mouthfeel.
