Cut chuck roast in small pieces - 1/2" to 3/4" cubes.
Heat 2 cups of water with the bouillon cubes and stir to combine. I use the microwave and a glass measuring cup.
Heat 1 tablespoon of oil over medium high heat in large cast iron skillet. When oil is shimmering, add about 1/3 of beef, spreading it out over the skillet to allow room to sear. Salt and pepper lightly when beef is in skillet.
Stir beef and allow to sear on all sides. Remove from skillet to a slow cooker sprayed with cooking spray. Repeat two more times until beef is all seared and in the slow cooker.
Add onions to skillet and allow to cook down for 3 to 5 minutes until softened. Add smashed garlic clove and paprika and stir, combining paprika with the onions and keeping mixture moving for about 3 minutes more.
Sprinkle flour over the onion mixture and allow to brown slightly, stirring for another few minutes.
Pour bouillon water over onions and stir until mixture thickens.
Pour/spoon the gravy over the beef in the crock pot and add the basil, caraway seeds and thyme. Combine well.
Cover crock pot and cook on low heat for 3 to 4 hours. Serve with sour cream and boiled, herbed potatoes.
