This Crockpot Cheesy Chicken Sausage Casserole is my big weeknight trick for full bellies with little fuss. The recipe slow simmers tender potatoes with savory chicken breast and smoky kielbasa, all blanketed in a creamy, cheesy sauce. The end result is pure comfort food and makes enough for family or for a few easy lunches.
The first time I tossed these ingredients in my slow cooker was on a cold Sunday when we needed something hearty after soccer. Now even my pickiest kid asks for seconds. The best part is how hands off it is after the chopping.
Ingredients
- Red potatoes: diced into half-inch cubes give a creamy bite and make this a one-pot meal Choose potatoes with smooth skins and no soft spots for best results
- Chicken breast: cut into one inch cubes brings lean, tender protein Check for firm, pink meat without bruising
- Kielbasa: sliced small adds smoky flavor and heartiness Look for kielbasa with natural casing and minimal fillers if possible
- Small white onion: diced creates aromatic sweetness in the base Use onions that are heavy for their size and have no green shoots
- Cheddar cheese: shredded packs melty richness Freshly shred for extra oozy texture
- Cream of chicken and herbs: makes the sauce creamy and flavorful Opt for low sodium if preferred
- Sour cream: lends a nice tang to balance the cheese Go for full fat for best texture
- Heavy cream: adds indulgence and a velvety finish
- Italian seasoning: gives herbal depth and aroma Make sure your blend is fresh for big flavor
- Garlic powder: offers mellow, savory punch Choose a high quality powder without anti-caking agents
- Salt and pepper: bring the flavors together Use kosher salt and freshly ground pepper if you have them
