Ingredients
- 2 lbs beef stew meat – cut into 1-inch cubes
- 1 tablespoon olive oil
- 1 large onion – chopped
- 3 cloves garlic – minced
- 4 medium carrots – sliced
- 3 medium potatoes – diced (or try substituting with sweet potatoes)
- 1 cup green beans – trimmed and halved
- 1 can (14.5 oz) diced tomatoes – undrained
- 2 cups beef broth
- 2 tablespoons Worcestershire sauce
- 1 teaspoon dried thyme
- 1 teaspoon dried basil

Instructions
Step 1:
In a large skillet, heat the olive oil over medium-high heat. Add the beef stew meat and brown it on all sides. This step adds flavor, so don’t skip it.
Step 2:
Transfer the browned beef to your slow cooker. In the same skillet, sauté the chopped onion and garlic until they are translucent, about 3-4 minutes. Add them to the slow cooker.
Step 3:
Layer in the carrots, potatoes, and green beans. Pour the diced tomatoes (with their juice) and beef broth over the top. Stir in the Worcestershire sauce, thyme, basil, salt, and pepper.
Step 4:
Cover and cook on low for 8-10 hours or high for 4-6 hours, until the beef is tender and the flavors have melded beautifully.

Healthier Alternatives
If you’re looking to lighten things up a little, consider using lean cuts of beef or replacing some of the potatoes with additional vegetables like zucchini or bell peppers. You can also use low-sodium broth to reduce the sodium content.
Serving Suggestions
This dish pairs wonderfully with crusty bread or a fresh green salad. For a delightful twist, serve it alongside my delicious Slow Cooker Lipton Potatoes, making for a comforting and complete meal.
Common Mistakes
One common mistake is adding too much liquid, which can leave your casserole soupy rather than stew-like. Make sure to follow the liquid measurements and trust that the vegetables will release some moisture as they cook. Also, avoid lifting the lid too often; slow cooking benefits from a steady heat.
Chef’s Notes
- For added depth of flavor, consider adding a splash of red wine to the casserole before cooking.
- You can assemble this casserole the night before and let it cook in the morning for a stress-free dinner.
- Don’t forget to taste before serving. Adding a touch more salt or fresh herbs can elevate the dish.
FAQs
- Q1: Can I use frozen meat for this recipe?
A1: Absolutely; Just remember to increase the cooking time if using frozen meat to ensure it cooks thoroughly. - Q2: What vegetables can I add?
A2: Feel free to get creative. Corn, peas, and even bell peppers work great in this casserole. - Q3: How do I store leftovers?
