Cozy Beef Diablo

The ‘diablo’ here is all about that zippy, slightly devilish sauce, not blazing heat. You whisk up a quick paste of mustard, chili sauce, Worcestershire, vinegar and a touch of sugar, then slather it over the beef roast before it goes into the crockpot.

As the meat cooks low and slow, that paste melts into a tangy, savory glaze and seasons everything beneath it. The smart part is the layering: sliced potatoes and onion go in the bottom, so they cook in the rendered juices and soak up all that flavor while the roast turns fork-tender above them.

It’s a true set-it-and-forget-it pot roast dinner: five minutes of prep in the morning, and you come home to a complete meal. No browning, no babysitting, just a roast and its sides done in one pot. Slice the beef and spoon the sauce and potatoes alongside.

Pro Tips

• Trim the excess fat off the roast first; in a slow cooker it renders out and makes the sauce greasy.
• Slice the potatoes and onions evenly and set them on the bottom so they cook through in the juices.
• Resist lifting the lid during cooking; every peek lets out heat and adds time.
• If the sauce is thin at the end, lift out the roast and stir a cornstarch slurry into the juices.

Variations

• Bump up the heat with a spoonful of hot chili sauce or a pinch of cayenne for a true diablo.
• Add carrots or mushrooms to the vegetable layer.
• Use a chuck roast for the most tender, fall-apart result.
