Beef Stew with Butternut Squash

I love butternut squash and try to use it as much as I can during the autumn months. This beef stew with butternut is really good, and a nice departure from more traditional beef stew. I found the recipe here.3 tbsp. olive oil1 chopped onion2 large minced cloves garlic1 tsp. ground dried rosemary1 tsp. dried thyme1/2 tsp. salt 1/2 tsp. pepper2 pounds beef stew meat, cut into 1 inch cubes1/4 cup
