Bring a large pot of salted water to a boil. Add your chosen 8 oz pasta and cook according to package instructions until al dente. Drain and set aside, reserving a little pasta water if desired.
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add 1 lb ground beef and cook, breaking it apart with a spoon, until browned and cooked through, about 6-8 minutes. Season with salt and pepper. Remove excess fat if desired.
Add the chopped onion, minced garlic, and diced bell pepper to the beef. Cook for another 5 minutes until the vegetables soften and the onion turns translucent.
Stir in 2 teaspoons paprika and 1 teaspoon dried oregano, allowing the spices to bloom for a minute. Pour in the entire can of diced tomatoes (with juice) and 1 cup beef broth. Simmer for 10 minutes, letting the flavors meld and the sauce reduce slightly.
Lower the heat and stir in 1/2 cup sour cream and 1 cup shredded cheddar cheese until melted and creamy. Taste and adjust seasoning with additional salt and pepper if needed.
Fold the cooked pasta into the sauce until evenly coated. If the sauce feels too thick, add a splash of reserved pasta water or extra broth to reach your desired consistency.
Spoon the creamy goulash-style pasta into bowls and garnish with fresh herbs if you like. Serve warm and enjoy your comforting meal.
