Heat up a tablespoon of olive oil in a large pot, preferably a non-stick one, over medium-high heat.
Once the oil is hot, you can add the chopped onion and sauté it over medium-high heat until it becomes soft and translucent. If the onion starts burning, make sure to reduce the heat.
Once the onion is ready, it is time to add the ground beef. Make sure to break it up using a wooden spoon and stir it into the sautéed onion.
Season the onion and meat mixture with salt, pepper, garlic powder, onion powder, oregano, rosemary, and chili flakes. Then, combine everything together.
It is important to cook the beef until it develops a golden brown color, as this process will release all the delicious meat juices and make the slumgullion that much more delicious.
Once the meat is ready, you can pour in the tomato sauce and add bouillon for more flavor.
Let the slumgullion cook on low for another 5-7 minutes. As we’ve mentioned, you can always choose to slow cook your American goulash if you’d like an even richer consistency and enhanced flavors.
Also, remember to stir the slumgullion frequently to prevent it from burning and sticking to the bottom of the pot.
Once the slumgullion is ready, it is time to add in your cooked pasta of choice, whether it be penne, rigatoni, gemelli, farfalle, spaghetti, or simple macaroni.
Combine the pasta with the goulash, and then mix in the shredded cheddar cheese while it is still hot so the cheese melts.
You can also add the cheese once you plate the slumgullion, as well as fresh parsley.
