This sheet pan dinner brings together smoky kielbasa, tender potatoes, and crisp green beans for a complete meal with minimal cleanup. I've perfected this recipe through countless weeknight dinners when time is short but I still want something satisfying and homemade.
I discovered this recipe during a particularly busy season of life when my kids had activities every evening. Now it's become our Tuesday tradition before soccer practice when we need something substantial but quick.
Ingredients
- Petite red potatoes: Chosen for their thin skins and ability to roast quickly
- Kielbasa sausage: Provides smoky flavor and protein without much prep work
- Yellow onion: Adds sweetness when roasted at high temperature
- Frozen green beans: Work perfectly and save prep time no need for fresh
- Olive oil: Helps everything roast evenly and adds richness
- Steak seasoning: Brings complex flavor in one simple ingredient
Step-by-Step Instructions
- Prep Your Ingredients:
- Preheat your oven to 400°F. Wash the potatoes thoroughly and slice them into 1inch pieces not too small or they might overcook before the other ingredients. Cut the kielbasa into medallions about 1/2 inch thick so they brown nicely without drying out. Dice the onion into 1inch chunks they should be fairly large to stand up to the roasting time.
- Assemble The Sheet Pan:
- Place the potatoes kielbasa onion and frozen green beans directly onto a large baking sheet. The frozen beans go straight from freezer to pan no thawing necessary which saves time and actually helps them maintain better texture. Drizzle everything with olive oil making sure to get good coverage. Sprinkle the steak seasoning evenly across all ingredients.
- Mix And Roast:
- Use your hands to toss everything together until all pieces are evenly coated with oil and seasoning. This ensures even cooking and flavor distribution. Make sure ingredients are spread in a single layer so they roast rather than steam. Place in the preheated oven for 20 minutes.
- Stir And Finish Cooking:
- After the initial 20 minutes remove the pan from the oven and give everything a thorough stir. This helps promote even browning and prevents any pieces from burning. Return to the oven for another 15 minutes or until the potatoes are fork tender and everything has a nice golden brown color around the edges.

Steak seasoning is my secret weapon in this dish. Most varieties contain salt pepper garlic onion paprika and sometimes a hint of chili all in one bottle. My grandmother actually taught me this trick when I was learning to cook in her kitchen it instantly elevates simple ingredients.
Time Saving Tips
You can prep all the ingredients the night before and store them in the refrigerator until ready to cook. Just remember to take the green beans from the freezer right before cooking.
Customization Options
This recipe welcomes substitutions based on what you have available. Sweet potatoes work wonderfully in place of red potatoes adding nutritional benefits and a different flavor profile. Turkey or chicken sausage can replace kielbasa for a lighter option.

Enjoy this quick and hearty meal with your loved ones—it's guaranteed to become a family favorite!
Frequently Asked Questions
- → Can I use fresh green beans instead of frozen?
Yes, you can substitute fresh green beans. Trim the ends and cut them into 2-inch pieces. They may cook slightly faster than frozen, so check for doneness around the 30-minute mark.
- → What type of steak seasoning works best?
Any brand of steak seasoning will work well. Montreal steak seasoning is a popular choice that provides a good balance of salt, pepper, garlic, and other spices. Adjust the amount based on your seasoning's salt content.
- → Can I substitute another type of sausage?
Absolutely! While kielbasa offers a great smoky flavor, you can use other pre-cooked sausages like andouille, smoked turkey sausage, or Italian sausage. Raw sausages will need to be fully cooked first before adding to the sheet pan.
- → How do I ensure everything cooks evenly?
Cut the potatoes into uniform 1-inch pieces and make sure ingredients are spread in a single layer without overcrowding the pan. The mid-cook stir is essential for even browning. If needed, use two sheet pans rather than cramming everything onto one.
- → What can I serve with this dish?
This is a complete meal on its own, but you could add a side salad or crusty bread to round it out. A dollop of sour cream or dijon mustard on the side makes a nice accompaniment to the savory flavors.
- → How do I store and reheat leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F oven for 10-15 minutes for the best texture, or microwave until heated through if you're in a hurry.
