In a Dutch oven, heat the olive oil and add in the beef, onion, and garlic.
Cook these over medium heat until the beef is browned and the onions are tender.
Add in the ketchup, salt, pepper, paprika, brown sugar, mustard powder, Tabasco sauce, and 3 cups of water.
Bring it to a boil, cover, and reduce the heat to a low simmer.
Crack the lid just a bit and simmer for 2 - 2 1/2 hours.
When it is almost done, cook your noodles.
When the goulash has finished cooking, you will thicken the sauce.
Increase the heat to bring the liquid to a boil. Whisk the corn starch and remaining 1/3 c water together in a small dish until smooth. Stir it into the sauce and let it cook for just a minute to thicken.
Place the cooked noodles and the goulash in a large serving bowl and toss to coat.
