Step-by-Step Instructions
1. Prepare the Roast
Pat your chuck roast dry with paper towels. Season it generously all over with salt and pepper. This step helps create a flavorful crust.
2. Sear the Beef (Optional but Recommended)
Heat olive oil in a large skillet over medium-high heat. Sear the roast for 2-3 minutes per side until browned. This adds depth of flavor to your beef dinner recipe.
3. Add Vegetables to the Slow Cooker
Place the chopped carrots, potatoes, and onion at the bottom of your slow cooker. Add the minced garlic over the vegetables. This forms a bed for the roast.
4. Place the Roast and Liquids
Transfer the seared roast to the slow cooker, placing it on top of the vegetables. Pour the beef broth and Worcestershire sauce over the roast and vegetables.
5. Season Your Pot Roast
Sprinkle the dried thyme and dried rosemary over the roast and into the broth. Cover your slow cooker with the lid.
6. Cook Until Tender
Cook on low for 6-8 hours or on high for 3-4 hours, until the beef is fork-tender. This slow cooking ensures a delicious beef dinner recipe.
7. Thicken the Gravy (Optional)
If you prefer a thicker gravy, whisk together cornstarch and cold water in a small bowl. Stir this mixture into the slow cooker liquid during the last 30 minutes of cooking.
Variation Ideas
- Add mushrooms or bell peppers along with the other vegetables.
- Stir in a can of diced tomatoes for a slightly different flavor profile.
- Serve over egg noodles or mashed potatoes instead of including potatoes in the slow cooker.
Storage Instructions
Store leftover slow cooker pot roast in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm portions in the microwave or on the stovetop over low heat until heated through.
Frequently Asked Questions (FAQ)
