Start by seasoning the flour with salt and pepper. Dredge each piece of steak in the flour until well coated. This step enhances both the flavor and the texture of the meat as it cooks.

In a large skillet, heat the vegetable oil over medium-high heat. Once the oil is hot, add the floured steak pieces. Sear them until they're nicely browned on both sides, about 3-4 minutes each. Not only does this create a beautiful crust, but it also locks in the flavors.

Now, layer the cooked steak into your slow cooker. Give it a moment to settle. Next, add the chopped onions, diced bell peppers, and sliced mushrooms atop the steak. These vegetables will not only add flavor but also moisture as they cook down.

In a separate bowl, mix together the beef consomme, diced tomatoes (with their juices), soy sauce, minced garlic, and smoked paprika. Stir well to combine. Pour this mixture over the beef and vegetables in the slow cooker. Make sure everything is well-coated.

Set your slow cooker to low heat and cook for about 7 to 8 hours. If you’re in a rush, you can set it to high for about 3-4 hours. The goal here is to allow the meat to become tender and for the flavors to meld beautifully.
