Ready to get cooking? Follow these simple steps, and you’ll be digging into cheesy potato perfection in no time!

Prep Time: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with cooking spray or butter.
Potato Power: Peel the russet potatoes and dice them into small cubes, about 1/2 inch in size.
Boil ‘Em Up: Place the diced potatoes into a large pot of water, making sure they are fully submerged.
Tender Time: Bring the pot of potatoes to a boil over medium-high heat and cook for about 10-12 minutes, or until the potatoes are just fork-tender but not fully soft.
Drain Away: Drain the potatoes well and set them aside to cool slightly.
Sausage Sizzle: While the potatoes are cooking, slice the kielbasa beef sausage into rounds about 1/4 inch thick.
Oil Up: Heat a large skillet over medium heat and add the olive oil.
Sausage Brown: Once the oil is heated, add the sliced kielbasa beef sausage to the skillet. Cook the beef sausage for about 5-7 minutes, stirring occasionally, until it is browned and slightly crispy on the edges.
Sausage Set Aside: Remove the kielbasa beef sausage from the skillet and place it on a plate to set aside.
Onion Time: In the same skillet, add the chopped onion and cook for about 3-4 minutes, stirring occasionally, until the onion becomes translucent and softened.
Spice It Up: Add the garlic powder, onion powder, paprika, black pepper, and salt to the skillet with the onions.
Stir and Sizzle: Stir the seasonings into the onions and cook for an additional 1-2 minutes until fragrant.
Combine Forces: In a large mixing bowl, combine the cooked potatoes, sautéed onions with seasonings, and the cooked kielbasa beef sausage.
Cheese Please!: Add the melted butter, sour cream, milk, and 1 1/2 cups of shredded cheddar cheese to the bowl and mix everything together gently until fully combined.
Baking Dish Bound: Transfer the mixture to the greased 9×13-inch baking dish and spread it out evenly.
Cheese Topping: Top the casserole with the remaining 1/2 cup of shredded cheddar cheese.
Bake It!: Place the casserole dish in the preheated oven and bake for about 20-25 minutes, or until the cheese on top is melted and bubbly.
Cool Down: Remove the casserole from the oven and let it cool for a few minutes.
Parsley Pop: Sprinkle the chopped parsley over the top of the casserole for a fresh pop of color and flavor.
Serve and Enjoy: Serve the Kielbasa beef sausage Cheesy Potato Casserole warm, and enjoy!

Pro Tips for Cheesy Potato Casserole Perfection

Want to take your casserole to the next level? Here are some pro tips from yours truly:

Potato Prep: Dice the potatoes evenly so they cook at the same rate.
Don’t Overcook: Make sure the potatoes are fork-tender, but not mushy, before adding them to the casserole.
Cheese Choice: Use a good quality cheddar cheese for the best flavor and melting.

Common Mistakes to Avoid

Even the easiest recipes can have pitfalls. Here’s what to watch out for:

Overcooked Potatoes: Mushy potatoes are no fun either. Aim for fork-tender.
Too Much Liquid: Drain the potatoes well to avoid a soggy casserole.
Burnt Cheese: Keep an eye on the casserole while it’s baking to prevent the cheese from burning.
