ManPoppet finished a project last night and we are celebrating here with the team (about 6 people). So, I have a 5 lb Round Roast and I want to try a new recipe. I like but don't love pot roast with carrots and celery and potatoes. I was hoping to serve this recipe with garlic mashed potatoes and roasted veg.

Has anyone done this high temp roasting method? Any tips? I have a meeting that will take me away for about 2 hours and this recipe seems to line up perfectly with that.

Thank you in advance everybody!!
