Sausage, green bean, and potato casserole fresh from the oven

Why You’ll Love It

Think of that smoky snap when you bite into a slice of kielbasa—like catching the scent of a crackling fire on a cool evening. The baby potatoes, with their silky centers and golden edges, offer a gentle sweetness against that charred spark. Green beans add a fresh, bright note that cuts through the richness, much like laughter breaking through a cozy chat. Then there’s the cheese, bubbling and pulling everything together in gooey harmony. Best of all, it’s a one-dish wonder: minimal hands-on fuss, a single baking pan to wash, and a table full of happy faces. Who could resist?

Timing and Servings

Prep takes about 15 minutes—just slicing, seasoning, and stirring everything together. Once the ingredients are snug in the pan, the dish bakes at 375°F: 30 minutes covered, then 10 minutes uncovered to crisp the cheese. You’ll be in and out of the kitchen in under an hour, perfect for busy weeknights or laid-back weekends. This recipe fills a standard 9×13-inch pan and serves 6 to 8 hungry folks (or fewer if someone has a hearty appetite).

Ingredients

  • 1 lb smoked kielbasa, sliced into ½-inch rounds
  • 1.5 lbs baby creamer potatoes, halved
  • 2 (14.5-oz) cans green beans, drained (or 12 oz fresh, trimmed)
  • 1 small onion, diced
  • 3 garlic cloves, minced
  • 1 cup chicken broth
  • ½ cup heavy cream (or half-and-half for a lighter touch)
  • 1 cup shredded sharp cheddar cheese
  • ½ tsp Cajun seasoning (Slap Ya Mama® works great), plus salt and pepper
  • 2 Tbsp olive oil

Directions

First, preheat your oven to 375°F and slick a 9×13 baking dish with oil or nonstick spray. Those baby potatoes shine when they get a little solo time in the pan. Heat 2 Tbsp olive oil in a large skillet over medium heat, then add the halved potatoes. Season with salt, pepper, and Cajun spice—just enough for a gentle kick—and let them sizzle for about 10 minutes, flipping occasionally until golden brown.

Slide the potatoes to one side and introduce the kielbasa rounds. Let them brown for 2–3 minutes per side for that smoky char. Stir in the diced onion and garlic and cook until the onion softens, about 2 minutes. Scrape up any browned bits—they’re flavor gold. Next, pour in the drained green beans, then add 1 cup chicken broth and ½ cup cream or half-and-half. Give everything a gentle swirl so each piece wears a silky coat.

Transfer the skillet mix—or the prepped filling—into your greased baking dish, spreading it out evenly. Blanket it with shredded cheddar, as though dusting it with edible sunshine. Cover with foil and bake for 30 minutes. Then peel back the foil and bake another 10 minutes, just long enough for the cheese to bubble and brown at the edges. If you’re chasing a crispier finish, pop the uncovered pan under the broiler for a minute—just don’t wander off; cheese moves from golden to charred. Let the casserole rest five minutes so the juices redistribute and every forkful holds together like a warm, hearty hug.

Variations

There are plenty of ways to tweak this: swap kielbasa for chicken or turkey sausage to lighten the load; pick a spicy andouille for a bolder profile; replace green beans with asparagus tips or roasted broccoli when spring hits; stir in sun-dried tomatoes or smoked paprika for more depth; switch the cream for Greek yogurt thinned with milk to cut richness. Go ahead—make it yours.

Storage & Reheating Tips

Leftovers are a gift on busy mornings. After serving, cool extra casserole at room temperature for up to 30 minutes, then tuck it into an airtight container and refrigerate for up to four days. To reheat, preheat the oven to 350°F, cover the dish with foil, and bake for about 15 minutes or until warmed through—no soggy corners allowed. Microwave single portions by stirring halfway through to avoid cold spots. For longer storage, freeze in an airtight dish or individual portions for up to three months; thaw overnight before reheating.

FAQs

Q: Can I put this together before company arrives?
A: Absolutely—you can prep everything through the broth-and-cream step, cover, and chill. When it’s dinner time, bake as directed, adding 5–10 extra minutes if it’s straight from the fridge.

Q: No heavy cream on hand—what now?
A: Half-and-half works nicely, or stir a tablespoon of cornstarch into whole milk for similar thickness.

Q: My crew isn’t a fan of green beans. Suggestions?
A: Broccoli florets, asparagus tips, or even sweet corn will all play nicely here.

Q: How spicy will this be?
A: Only as fiery as you make it. Cut back the Cajun seasoning for a milder dish or crank it up for real heat.

Conclusion

There’s something timeless about gathering around a steaming casserole after the temperature dips, spooning out cheesy, savory bites that feel like childhood wrapped in a skillet. This sausage, green bean, and potato dish hits all the marks—nostalgia, comfort, and ease. Pair it with crusty bread and a crisp winter salad for a meal that checks every box. Let that cheesy goodness remind you that simple ingredients can shine bright when given a little love.
