This crockpot sausage casserole has been my secret weapon for busy weeknights when I need something hearty that practically cooks itself. The slow cooking process transforms simple ingredients into a rich, flavorful meal that tastes like you spent hours in the kitchen, not just minutes on prep.
I first created this recipe during a particularly hectic week when my family needed comfort food but I had zero time to stand over the stove. Now it's requested at least twice a month, especially during the colder seasons when we need something substantial.
Ingredients
- 1 lb smoked sausage sliced into rounds: offers rich smoky flavor that infuses the entire dish look for ones with visible herbs or seasonings in the casing
- 4 potatoes diced: provides hearty texture and helps thicken the sauce naturally waxy varieties hold their shape best
- 1 onion chopped: forms the aromatic base of the casserole sweet varieties add subtle depth
- 1 bell pepper chopped: adds color and slight sweetness red peppers provide the most flavor
- 1 can 14.5 oz diced tomatoes: brings acidity and richness choose fire-roasted for extra depth
- 2 cups chicken broth: creates the silky sauce that ties everything together homemade provides the best flavor
- 1 tsp paprika: adds earthy warmth and beautiful color Hungarian sweet paprika works wonderfully
Step-by-Step Instructions
- Prep The Ingredients:
- Begin by slicing your sausage into even rounds about half an inch thick. Dice the potatoes into chunks roughly one inch in size for even cooking. Chop the onion and bell pepper into similar sized pieces so everything cooks at the same rate. Having all ingredients prepped before assembly ensures nothing gets forgotten.
- Layer The Components:
- Start by placing the diced potatoes at the bottom of your crockpot this helps them cook thoroughly as they need the most time. Add the sliced sausage, chopped onion, and bell pepper on top. Pour in the diced tomatoes with their juice and add the chicken broth. Sprinkle the paprika evenly across the top. No stirring needed at this point.
- Set And Forget:
- Cover the crockpot with its lid and set to low for 5 to 6 hours. The slow cooking allows the flavors to meld together beautifully while tenderizing the potatoes. About halfway through cooking time, gently stir once to ensure even distribution of flavors throughout the casserole. Then replace the lid and continue cooking until potatoes are fork tender.

The smoked sausage is truly the star of this dish. I discovered this by accident one day when I substituted regular sausage for the smoked variety and noticed a dramatic difference in flavor. The smokiness permeates every bite, creating a depth that makes people think you spent hours developing the flavors. My husband now specifically asks for the "smoky potato pot" whenever he sees sausage in our fridge.
Storage Instructions
This casserole keeps wonderfully in the refrigerator for up to 4 days in an airtight container. The flavors actually continue to develop overnight, making leftovers sometimes even more delicious than the first serving. For best results when reheating, warm gently on the stovetop with a splash of broth to maintain the moisture. If freezing, portion into individual containers for easy thawing and let cool completely before transferring to the freezer.
Making It Your Own
The beauty of this recipe lies in its flexibility. Try using sweet potatoes for a nutritional boost and slightly sweeter profile. Kielbasa makes an excellent sausage option, while Italian sausage adds a completely different but equally delicious flavor profile. For a spicier version, add a teaspoon of red pepper flakes or a diced jalapeño. You can also incorporate additional vegetables like carrots, celery, or even kale added in the last hour for extra nutrition.

Serving Suggestions
This hearty casserole stands perfectly on its own, but pairs wonderfully with crusty bread for soaking up the flavorful sauce. A simple green salad with a vinaigrette dressing provides a fresh contrast to the rich casserole. For special occasions, serve with garlic bread and a glass of medium-bodied red wine. During summer months, I often add a fresh tomato and cucumber salad on the side for brightness.
Common Recipe Questions
- → Can I substitute different types of sausage?
Yes! While smoked sausage provides excellent flavor, you can substitute with kielbasa, Italian sausage, chicken sausage, or even a vegetarian alternative. Each will create a slightly different flavor profile but will work well in this slow-cooked dish.
- → What can I serve with this casserole?
This hearty dish works well with a simple green salad, crusty bread, or steamed green vegetables like broccoli or green beans. For a lighter option, serve it with a side of roasted vegetables or coleslaw.
- → Can I freeze the leftovers?
Yes, this casserole freezes well. Allow it to cool completely, then portion into airtight containers. Freeze for up to 3 months. Thaw overnight in the refrigerator and reheat thoroughly on the stovetop or microwave until piping hot.
- → How can I make this dish spicier?
For extra heat, add red pepper flakes, diced jalapeños, or a dash of hot sauce to the crockpot before cooking. You could also stir in some cayenne pepper or use a spicy sausage variety instead of the regular smoked sausage.
- → Can I cook this on high instead of low?
Yes, you can cook this casserole on high for approximately 3-4 hours instead of 5-6 hours on low. However, cooking on low is generally preferred as it allows the flavors to develop more fully and ensures the potatoes cook evenly without becoming mushy.
- → What type of potatoes work best in this casserole?
Waxy potatoes like Yukon Gold or red potatoes hold their shape well during slow cooking. Russet potatoes will work but may break down more during cooking. Baby potatoes are also excellent as they require minimal preparation and maintain their texture.
