The secret to a delicious pot roast is to intensify flavor by searing the meat, and that’s what you’ll learn how to do with this super-basic recipe. After that, you’ll sauté vegetables and herbs in the hot pan, then put the whole thing into the oven to cook slowly for 2½ to 3 hours. That’s it! Master this technique, and you’re ready to tackle other kinds of pot roasts, both for the oven and the slow cooker. One important thing to note: A pot roast is not the same as a prime rib roast. The best beef pot roasts are made with tough, gnarly cuts like beef chuck roast; using spendy beef to make pot roast is a waste. So save your bucks and go for the chuck.
