How to Make Crockpot Mississippi Kielbasa & Cheesy Potatoes
-
Prepare the crockpot: Start by using a 6-quart crockpot. Cut the kielbasa into thick rounds, dice the onion, and chop the Yukon Gold potatoes into evenly sized 1-inch cubes to ensure consistent cooking.
-
Layer the ingredients: Add the cubed potatoes to the bottom of the crockpot. Scatter the diced onion over the potatoes, then neatly arrange the sliced kielbasa on top, creating a beautiful base for your casserole.
-
Add seasonings: Sprinkle the ranch seasoning and au jus gravy mix evenly over the sausage and potatoes, allowing the spices to infuse their flavors throughout the dish.
-
Top with butter and peppers: Place the cubed butter and whole pepperoncini peppers on top of the layered ingredients. Pour in the pepperoncini juice and chicken broth for added moisture.
-
Cook it slow: Cover the crockpot and cook on LOW for 5–6 hours or HIGH for 3–4 hours. You’ll know it’s ready when the potatoes are fork-tender and the flavors are wonderfully melded.
-
Stir in creaminess: Once the potatoes are tender, gently stir the mixture. Add the sour cream and 1½ cups of shredded cheddar cheese, stirring until it’s all beautifully combined.
-
Melt the cheese: Sprinkle the remaining ½ cup cheddar cheese over the top. Cover and cook on LOW for an additional 10–15 minutes, or until the cheese is melty and creamy.

Expert Tips for Crockpot Mississippi Kielbasa & Cheesy Potatoes

Crockpot Mississippi Kielbasa & Cheesy Potatoes Recipe FAQs
How do I select the best potatoes for this recipe?
Absolutely! When choosing potatoes for the casserole, Yukon Gold potatoes are ideal due to their creamy texture and rich flavor. Look for potatoes that are smooth and free of blemishes or dark spots. They should feel heavy for their size and have a firm texture.
How should I store leftover Crockpot Mississippi Kielbasa & Cheesy Potatoes?
Certainly! After enjoying your delicious casserole, allow any leftovers to cool completely. Transfer them to an airtight container and store in the refrigerator for up to 3 days. This helps maintain freshness and flavor. If you plan to keep it longer, consider freezing individual portions instead!
Can I freeze this casserole, and how?
The more the merrier! To freeze Crockpot Mississippi Kielbasa & Cheesy Potatoes, allow the casserole to cool to room temperature. Then, scoop it into freezer-safe containers or resealable bags, making sure to expel as much air as possible. It can be frozen for up to 2 months. When you’re ready to enjoy it, thaw it in the refrigerator overnight before reheating!
What should I do if my potatoes aren’t tender after cooking?
Very well! If you find that your potatoes aren’t fork-tender after the suggested cooking time, simply extend the cooking duration. For LOW, add an extra hour, and for HIGH, try another 30 minutes. Make sure to check for doneness regularly after this period. The key is that all potatoes should be soft and beautifully melded with the other flavors!
Are there any dietary considerations I should be aware of?
Absolutely! If you’re serving this dish to guests with dietary restrictions, note that it contains meat, dairy, and gluten. If needed, consider using gluten-free ranch seasoning and au jus gravy mix to accommodate gluten allergies.
