Roasted Brussels Sprouts with Walnuts 4-6 side servings 1 pound Brussels sprouts 2 tablespoons balsamic vinegar 1-2 tablespoons olive oil coarse sea salt 1/2 cup chopped walnuts Parmesan cheese (optional) Preheat your oven to 375 degrees F. Cut the Brussels sprouts in half, trying to make sure each piece is a similar size so they'll roast evenly. Place the Brussels sprouts on a roasting pan and drizzle with olive oil and balsamic vinegar. Toss until evenly coated. Sprinkle to taste with coarse sea salt. Roast for 25-30 minutes, stirring once or until Brussels sprouts begin to brown. Remove pan from oven. Stir Brussels sprouts again and add walnuts. Roast for another five minutes or until walnuts are browned. Sprinkle with parmesan cheese (optional) and serve immediately. Back to Dinner Recipes
