Mushroom Lentil Barley Casserole: A Rustic Vegan Delight

I’ll never forget the first time I made this casserole. It was a blustery autumn evening, the kind where the scent of woodsmoke hangs heavy in the air. My sister, a long-time vegetarian, was visiting, and I wanted to create something hearty and comforting that even a dedicated carnivore like myself would love. The earthy aroma that filled the kitchen as the mushrooms browned and the lentils simmered was simply intoxicating. That first bite, the nutty barley mingling with the savory mushrooms, sealed the deal – this casserole became a cherished staple in our family meals.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 1 hour 5 minutes
• Total Time: 1 hour 25 minutes
• Servings: 4
• Yield: 1 casserole
• Dietary Type: Vegan

Ingredients

• 1 tablespoon olive oil
• 8-12 ounces shallots or pickling onions, peeled
• 1 1⁄2 lbs mixed mushrooms, in thick slices (a mix of wild or exotic ones like oyster, shiitake, enoki and chestnut mushrooms is great)
• 2 garlic cloves, minced
• 4 ounces pearl barley
• 4 ounces red lentils
• 2 tablespoons soy sauce
• 3 tablespoons dry sherry
• 3⁄4 – 1 pint vegetable stock
• 2 tablespoons chopped fresh herbs (rosemary, thyme and parsley) or 2 tablespoons dried herbs, equivalent
• 1 bay leaf
• Salt & freshly ground black pepper to taste

Equipment Needed

• Large skillet or Dutch oven
• Covered casserole dish (optional)
• Knife
• Cutting board

Instructions

1. Begin by heating the olive oil in a large skillet or Dutch oven over medium heat. Add the shallots or pickling onions and cook gently, stirring occasionally, until they are softened and nicely browned. This should take about 10-15 minutes. Don’t rush this step; the caramelized onions add a wonderful depth of flavor.
2. Add the sliced mushrooms and minced garlic to the skillet. Increase the heat to high and cook, stirring frequently, until the mushrooms start to release their juices and begin to brown. This usually takes around 8-10 minutes. Be careful not to overcrowd the pan; cook the mushrooms in batches if necessary to ensure they brown properly.
3. Stir in the pearl barley, red lentils, soy sauce, dry sherry, fresh or dried herbs, and 3/4 pint of vegetable stock. Add the bay leaf.
4. Bring the mixture to a boil, then reduce the heat to low. At this point, you have two options for cooking:
   • Oven Method: Transfer the mixture to a covered casserole dish and bake at 350°F (180°C) for 45 minutes.
   • Stovetop Method: Cover the skillet or Dutch oven and simmer on top of the stove for 25-30 minutes.
5. Regardless of which cooking method you choose, it is important to check the casserole periodically during cooking. The barley and lentils should be cooked through, and most of the liquid should be absorbed. If the mixture becomes too dry, add more vegetable stock a little at a time, stirring to incorporate it.
6. Once the barley and lentils are cooked, remove the bay leaf. Taste the casserole and adjust the seasoning as needed. It likely won’t need much salt because the soy sauce and vegetable stock contribute a good amount of sodium, but a generous grind of black pepper is always a welcome addition.
7. Let the casserole sit for a few minutes before serving. This allows the flavors to meld together even further.

Expert Tips & Tricks

• For a richer, deeper flavor, use a combination of dried and fresh mushrooms. Soak dried mushrooms in hot water for about 20 minutes to rehydrate them, then chop them and add them to the casserole along with the fresh mushrooms. Don’t discard the soaking liquid; strain it and add it to the casserole for extra flavor.
• If you’re short on time, you can use pre-cooked barley and lentils. Simply add them to the casserole during the last 15 minutes of cooking, or until heated through.
• To enhance the umami flavor, add a tablespoon of tomato paste along with the mushrooms and garlic.
• Don’t be afraid to experiment with different herbs. Sage, thyme, and rosemary all pair beautifully with mushrooms and lentils.
• For a smoother, creamier texture, stir in a dollop of vegan cream cheese or a splash of coconut milk at the end of cooking.
