Ingredients You’ll Need
The magic of this casserole lies in its straightforward yet flavorful ingredients, each adding a unique layer of taste, texture, and color that comes together beautifully in the final bake.

- Shredded cheddar cheese (2 cups): Infuses cheesy creaminess that melts throughout the casserole.
- Condensed cream of chicken soup (10.5 oz can): A creamy binder that keeps everything moist and flavorful.
- Sour cream (1 cup): Adds tang and richness, making every bite smooth and luscious.
- Garlic powder (½ teaspoon): Infuses a mild garlic aroma essential for that comforting flavor profile.
- Black pepper (½ teaspoon): A subtle heat that enhances the overall taste.

- Chopped green onions (¼ cup, optional): Offers a fresh, slightly sharp contrast and a pop of color when sprinkled on top.
How to Make Cheesy Kielbasa Hashbrown Casserole Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating the oven to 375°F and lightly greasing a 9×13-inch baking dish. This simple step ensures your casserole won’t stick and will come out beautifully crisp on the edges.
Step 2: Cook the Kielbasa
Heat olive oil in a large skillet over medium heat. Add the sliced kielbasa and cook for about 3 to 4 minutes on each side until it’s lightly browned and wonderfully fragrant. Browning the kielbasa develops a savory crust that adds irresistible flavor throughout the casserole.
Step 3: Sauté the Onions
Using the same pan, toss in the diced yellow onion. Sauté for 3 to 5 minutes until they’re softened and aromatic. These onions bring a subtle sweetness that balances the saltiness of the sausage beautifully.
Step 4: Combine All Ingredients
In a large mixing bowl, mix together the thawed hashbrowns, browned kielbasa, sautéed onions, shredded cheddar cheese, condensed cream of chicken soup, sour cream, garlic powder, black pepper, and salt. Stir everything until it’s evenly combined — this is the heart of your casserole, full of texture and flavor waiting to meld in the oven.
Step 5: Bake to Perfection
Transfer the mixture to your prepared baking dish and spread it evenly. Bake uncovered for 40 to 45 minutes, until the top turns a beautiful golden brown and begins bubbling with cheesy goodness. The bubbling signals that all the flavors have married perfectly.
Step 6: Add the Finishing Touches
Once out of the oven, let your casserole cool slightly—patience is key! Then sprinkle with chopped green onions if you like a fresh finish. These add a lovely color contrast and a gentle crunch that lifts the rich flavors.

Garnishes
A sprinkle of fresh green onions or finely chopped parsley adds a fresh pop and a bit of color, making the casserole feel even more inviting. If you like a little extra texture, consider a handful of crispy bacon bits or a drizzle of hot sauce for a kick.
Side Dishes
This dish shines as a standalone hearty meal, but pairing it with a crisp green salad or roasted vegetables can lighten the plate and add contrasting flavors. Steamed broccoli or roasted Brussels sprouts complement the richness wonderfully without competing with the casserole’s bold flavors.
Creative Ways to Present
Turn your Cheesy Kielbasa Hashbrown Casserole Recipe into individual portions by baking in ramekins or muffin tins for a fun, grab-and-go option. You can also top the casserole with crushed butter crackers or extra shredded cheese in the last 10 minutes for a crunchy, golden crust that adds a delightful twist.
Make Ahead and Storage
Storing Leftovers
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. The casserole tastes just as comforting reheated, making it perfect for preparing ahead of busy weekdays.
Freezing
This casserole freezes beautifully. To freeze, cool completely, then cover tightly with foil and plastic wrap to avoid freezer burn. It will keep well for up to 2 months, making it a lifesaver for meal prep or unexpected guests.
Reheating
Reheat leftovers in a 350°F oven for about 20 minutes or until warmed through to preserve that crisp top layer. Alternatively, microwave individual portions for a quicker option, although the texture of the top won’t stay quite as crisp.
FAQs
Can I use fresh potatoes instead of frozen hashbrowns?
While fresh shredded potatoes can work, frozen hashbrowns save time and ensure consistent texture. Just be sure to thaw them completely before mixing to avoid excess moisture in your casserole.
Is there a substitute for the cream of chicken soup?
You can use cream of mushroom or cream of celery soup if you prefer, or make a homemade creamy sauce to keep the casserole rich without canned ingredients.
Can I make this recipe dairy-free?
Yes! Swap out the cheddar cheese and sour cream for dairy-free alternatives. Using a dairy-free cream soup substitute will help keep the casserole creamy while accommodating dietary needs.
What type of kielbasa is best for this casserole?
Traditional smoked kielbasa offers the best flavor, but turkey kielbasa or smoked sausage work well too. Just choose your favorite, and the casserole will turn out delicious.
Can I add vegetables to the casserole?
Absolutely. Diced bell peppers, mushrooms, or spinach can be sautéed with the onions to add nutrition and flavor twists to the classic recipe.
