This one-pan meal combines flavorful kielbasa, soft potatoes, and snappy green beans for a full dinner with hardly any cleanup afterward. I've tweaked this dish through many busy weeknights when I'm short on time but still want something tasty and homemade.
I stumbled onto this meal during an incredibly hectic time when my children had activities every night. It's now our Tuesday go-to before soccer when we need something filling yet fast.
What You'll Need
- Baby red potatoes: Perfect because their thin skins don't need peeling and they cook quickly
- Kielbasa sausage: Adds smoky taste and protein without any complicated prep
- Yellow onion: Gets deliciously sweet when cooked at high heat
- Frozen green beans: Do the job perfectly and cut down on prep time versus fresh
- Olive oil: Makes everything roast properly and gives depth
- Steak seasoning: Delivers rich flavor in just one ingredient
How To Make It
- Get Everything Ready:
- Set your oven to 400°F. Clean the potatoes well and cut them into 1inch chunks not too tiny or they'll cook too fast compared to other stuff. Slice the kielbasa into 1/2 inch rounds so they'll brown nicely without getting dry. Chop the onion into 1inch pieces they should be pretty big to handle the cooking time.
- Load Up Your Pan:
- Dump the potatoes kielbasa onion and frozen green beans right onto a big baking sheet. The frozen beans can go straight from freezer to pan don't bother thawing them it actually helps them keep better texture. Pour olive oil over everything making sure it's all coated. Sprinkle steak seasoning all over.
- Toss And Bake:
- Get in there with your hands and mix everything until all pieces have oil and seasoning on them. This makes sure it all cooks and tastes the same. Spread everything out in one layer so it roasts properly instead of steaming. Stick it in the hot oven for 20 minutes.
- Mix And Finish Up:
- When 20 minutes pass pull the pan out and stir everything around. This helps it all brown evenly and stops anything from burning. Put it back in for another 15 minutes or until you can easily stick a fork in the potatoes and everything looks golden brown at the edges.

Steak seasoning works like magic in this meal. Most types have salt pepper garlic onion paprika and sometimes a bit of chili all mixed together. My grandma showed me this trick when I was cooking in her kitchen as a kid it makes simple foods taste fancy right away.
Quick Shortcuts
You can cut everything up the night before and keep it in the fridge until cooking time. Just grab the green beans from the freezer right before you're ready to cook.
Switch It Up
Feel free to swap ingredients based on what's in your kitchen. Sweet potatoes make a great stand-in for red potatoes adding extra nutrients and different flavor. Turkey or chicken sausage works instead of kielbasa if you want something lighter.
What To Serve With It
This dish works perfectly by itself but tastes even better with a basic green salad with tangy dressing for a meal that feels like dining out. If you've got big eaters add some crusty bread to soak up all the tasty oil left on the pan.

Dig into this fast and filling dinner with your family—it'll soon become a regular request at your table!
Frequently Asked Questions
- → Can I use fresh green beans instead of frozen?
Sure thing! Fresh green beans work great. Just cut off the ends and snap them into 2-inch pieces. They might cook a bit quicker than frozen ones, so take a peek around 30 minutes to make sure they're not overdone.
- → What type of steak seasoning works best?
Any steak seasoning you have will do the job. Many folks like Montreal steak seasoning for its mix of salt, pepper, garlic and spices. Feel free to use more or less depending on how salty your seasoning is.
- → Can I substitute another type of sausage?
For sure! Kielbasa gives a nice smoky taste, but you can swap in other ready-to-eat sausages like andouille, smoked turkey sausage, or Italian sausage. If you want to use uncooked sausages, make sure to cook them completely before adding them to your pan.
- → How do I ensure everything cooks evenly?
Cut your potatoes about the same size, around 1-inch chunks, and spread everything out in one layer without cramming the pan. Don't skip stirring halfway through - it helps everything brown nicely. If your pan looks too full, grab a second one instead of piling everything up.
- → What can I serve with this dish?
This dish stands alone as a full meal, but a simple green salad or some crusty bread can round things out nicely. A spoonful of sour cream or some dijon mustard on the side goes really well with these savory flavors.
- → How do I store and reheat leftovers?
Pop any extras in a sealed container in the fridge and eat within 3 days. For the best results, warm it up in a 350°F oven for 10-15 minutes to keep everything crispy. If you're in a rush, the microwave works too - just heat until it's warm throughout.
