🍋 Simply Made Suggestions & Swaps …

• Cooking for a crowd? Use a larger roast and adjust the cooking time as needed.
• Don’t skip the sear: Browning the roast first adds extra flavor. It’s a few additional minutes that are worth it.
• Add potatoes: Toss baby potatoes or chopped potatoes into the slow cooker with the carrots and onions for an easy all-in-one dinner.
• Switch up the vegetables: Celery or mushrooms would also work well here.
• Make it extra savory: Add another splash of Worcestershire sauce if you like a deeper beefy flavor.
• Slow cookers vary: Start checking the roast around the 6-hour mark. It’s ready when the beef easily pulls apart with a fork.
