Prepare the Beef and Vegetables: First, season the beef with salt and pepper. In a large pot, heat a drizzle of olive oil over medium-high heat, and brown the beef on all sides. Then, transfer the beef to a bowl. Meanwhile, in the same pot, add the diced onions, carrots, and celery, cooking them until they soften and become lightly caramelized. Next, add garlic and stir for another minute.
Build the Flavor Base: Once the vegetables are tender, return the beef to the pot and mix in the cubed potatoes and diced tomatoes. Then, pour in the beef broth, grape juice, and apple cider vinegar. Stir well to combine all ingredients, ensuring that the flavors start to meld together. Additionally, sprinkle in the dried rosemary, thyme, and basil.
Simmer to Perfection: Bring the mixture to a gentle simmer, cover the pot, and reduce the heat to low. Allow the casserole to cook for about 2 hours, stirring occasionally. Meanwhile, if you decide to add green beans, incorporate them during the last 20 minutes of cooking. This ensures they remain crisp and add a fresh contrast to the dish.
Final Touches and Serving: Once the beef is tender and the vegetables have absorbed the savory broth, taste the casserole and adjust seasoning if needed. Finally, remove from heat, garnish with freshly chopped parsley, and serve warm. Enjoy your rich, fulfilling meal as it fills your kitchen with inviting aromas and flavors.
