Step 1: Prepare the Beef

1. In a large bowl, toss the beef cubes with the flour, salt, and black pepper until evenly coated. This helps the meat develop a nice crust during browning and thickens the sauce.
2. Heat the vegetable oil in a large Dutch oven or heavy-bottomed pot over medium-high heat.
3. Add the beef in batches, ensuring the pieces are not overcrowded. Brown each side for about 2-3 minutes, then transfer the seared beef to a plate. Repeat with the remaining beef.

Step 2: Sauté the Vegetables

1. In the same pot, lower the heat to medium and add the chopped onion. Sauté for 5-6 minutes, or until softened and translucent.
2. Stir in the red and green bell peppers and cook for another 4-5 minutes until slightly softened.
3. Add the minced garlic and cook for 1 minute, or until fragrant.

Step 3: Build the Sauce

1. Sprinkle the sweet paprika and hot paprika over the sautéed vegetables and stir to coat evenly. This step toasts the spices, enhancing their flavor.
2. Pour in the beef broth, scraping up any browned bits from the bottom of the pot with a wooden spoon.
3. Add the crushed tomatoes, Worcestershire sauce, and caraway seeds (if using). Stir to combine.

Step 4: Simmer the Beef

1. Return the browned beef to the pot along with any accumulated juices. Stir to coat the beef in the sauce.
2. Reduce the heat to low, cover the pot, and let the beef simmer gently for 1 ½ to 2 hours, or until it’s tender and flavorful. Stir occasionally to prevent sticking.

Step 5: Add the Sour Cream

1. Once the beef is tender, remove the pot from the heat. Stir in the sour cream until fully incorporated, creating a creamy and velvety sauce.
2. Taste and adjust the seasoning with additional salt or pepper if needed.

Step 6: Cook the Noodles

1. While the beef is simmering, cook the egg noodles according to package instructions. Drain and toss with butter for added richness, if desired.

Step 7: Serve and Garnish

1. Serve the Beef Paprikash over the buttered noodles, rice, or mashed potatoes.
2. Garnish with freshly chopped parsley for a pop of color and flavor.
