Serving up the ultimate homemade pot roast is a cinch with our handcrafted sauce. We start by combining sweet caramelized onions with the rich, earthy flavors of porcini mushrooms, adding hearty Merlot red wine, fragrant herbs and roasted garlic. Ingredients are slow-simmered for hours to ensure deep, complex flavor. Prep couldn't be simpler—just combine the sauce with seared beef brisket, then finish in the oven. For a great dinner, serve your pot roast with mashed potatoes or buttered noodles.

  • Rated 5 out of 5 by from So good I had to... create an account on so that I could post a response to the one other review of this... I stumbled across this around a year ago and decided to give it a try. Literally, my entire family was slurping the sauce off of the plate. While it may not be everyone’s taste, I have yet to prepare this for family or guests that have not raved about “my” pot roast and requested it again and again... so I just HAD to throw my two cents in. This sauce is a staple in our pantry. Love. Love. Love.
