In a large pot or Dutch oven, heat the vegetable oil over medium-high heat. Add the meat and cook until browned on all sides, stirring occasionally.
Add the chopped onions and minced garlic to the pot and cook until the onions are soft and translucent.
Add the chopped bell peppers, sliced carrots, and sliced celery to the pot and cook for 5-7 minutes, until the vegetables have softened.
Add the cubed potatoes, canned diced tomatoes, tomato paste, beef broth, paprika, thyme, rosemary, salt, black pepper, and bay leaves to the pot. Stir everything together and bring to a boil.
Reduce the heat to low, cover the pot with a lid, and let the stew simmer for 1 1/2 to 2 hours, or until the meat is tender and the vegetables are fully cooked.
In a small bowl, whisk together the all-purpose flour and water to make a slurry. Add the slurry to the pot and stir well. Let the stew simmer for another 10-15 minutes, or until the sauce has thickened.
Remove the bay leaves and serve the Bosnian Jahnija hot with rice or bread.
