Tried this for dinner last week and used a slow cooker for the whole thing for about 10 hours after browning the meat on the stove – it was incredible!! Amazing flavor, loved all of the onions and the amount of gravy it made too. We’ll be making it again!
Absolutely delicious. Ever since we have used this recipe I dont make it any other way.
Sorry I meant to add a 5 start with my previous comment
So easy, but the results were mouthwatering restaurant quality. Honestly, the best pot roast I’ve ever made. My roast was under two pounds and I cooked it in the oven at 300° to slow down the process given its smaller weight. It was perfect!
❤️ Love Hearing this!!
Best roast we ever had! Made exactly as written. Husband said not to wait too long to make again.
