Notes
Expert Recipe Tips:
Choose the Right Cut of Meat. Round steak, chuck steak, and blade steak work best for this recipe because they become tender when cooked low and slow. Look for well-marbled cuts, as they add more flavor.
Use the Right Cooking Time & Temperature. Cooking on LOW for 8 hours gives the best results. Cooking on HIGH may make the meat tougher, as it doesn’t allow enough time for the connective tissues to break down properly.
Don’t Skip the Acidic Ingredients. Tomatoes help tenderize the meat due to their natural acidity. If substituting, use tomato sauce, crushed tomatoes, or even a splash of balsamic vinegar for a similar effect.
Thicken the Sauce Properly. To avoid lumps, always mix cornstarch with cold water before adding it to the slow cooker. Let it cook for another 20 minutes on HIGH to thicken properly. If the sauce is still too thin, add more cornstarch slurry in small amounts.
Avoid Lifting the Lid Too Often. Every time you lift the lid, heat escapes, which can add 20-30 extra minutes to your cooking time. Try to check the dish only when necessary.
Store & Reheat for Best Results. Leftovers taste even better the next day as the flavors continue to develop. When reheating, add a splash of broth or tomato sauce to keep it from drying out.
Serve It with the Right Side Dishes. This dish pairs well with mashed potatoes, rice, egg noodles, or even polenta to soak up the delicious sauce. A fresh salad or steamed veggies like green beans, asparagus, or carrots will balance out the richness of the dish.
 Storage: Store leftovers in an airtight container in the fridge for 3-4 days.To freeze, place in a sealed container for up to 3 months.Reheat in the microwave or on the stovetop over low heat.
