Step 1: Cook the Kielbasa

1. Heat the Skillet: Start by heating a large skillet over medium heat. Add the olive oil and let it warm up.
2. Sauté the Kielbasa: Add the sliced kielbasa sausage to the skillet and cook for 5-7 minutes, or until it’s browned and slightly crispy. This helps to release the savory flavor into the oil. Once done, remove the kielbasa from the skillet and set it aside.

Step 2: Sauté the Vegetables

1. Cook the Onion: In the same skillet, add the diced onion and sauté for 3-4 minutes until softened and translucent.
2. Add Seasoning: Sprinkle in the garlic powder, paprika, salt, and pepper. Stir to combine, allowing the spices to bloom for a minute.

Step 3: Add the Hash Browns

1. Cook the Hash Browns: Add the frozen hash browns (or fresh ones, if you prefer) to the skillet. Spread them out in an even layer and let them cook for about 10-12 minutes, flipping halfway through. You want them golden and crispy on both sides.
2. Return Kielbasa: Once the hash browns are crisp, return the cooked kielbasa to the skillet and stir everything together. Let it cook for an additional 3-4 minutes to combine the flavors.

Step 4: Add the Cheese

1. Melt the Cheese: Sprinkle the shredded cheddar cheese over the top of the hash browns and kielbasa. Cover the skillet with a lid and cook for another 2-3 minutes until the cheese is melted and gooey.

Step 5: Serve

1. Garnish and Enjoy: Once the cheese has melted, remove the skillet from the heat. Garnish with freshly chopped parsley if desired. Serve hot and enjoy!
