This easy sheet pan sausage green beans and potatoes has become one of my favorite solutions for a no-fuss weeknight dinner. Everything roasts together in the oven for a hearty meal that fills the kitchen with comfort food aromas and gives you plenty of hands-off time while it cooks.
My family first tried this recipe after a trip to a local farm where we brought home fresh green beans and potatoes. It instantly reminded me of classic southern comfort food but with far less effort at the end of a long day.
Ingredients
- Baby potatoes: The star ingredient for a filling bite Use potatoes that feel firm to the touch and avoid any with green spots
- Green beans: Fresh and tender beans add color and crunch Look for snap beans with a bright green color and no wilting
- Yellow onion: This sweetens and builds flavor Choose onions with firm skins and no visible soft spots
- Pre-cooked andouille sausage or kielbasa: Brings smoky richness to the dish Choose quality sausage with minimal added sugars for best flavor
- Olive oil: Helps everything roast and brown Choose extra virgin olive oil for the best taste
- Garlic powder: Delivers mellow savory depth Make sure it is still aromatic and not clumpy
- Salt: Essential to highlight all the flavors Use kosher or sea salt for more even seasoning
- Italian seasoning blend: Adds a mix of herbs for earthy flavor Use a blend with oregano basil and rosemary for the most fragrance
- Ground black pepper: Rounds out the seasonings with subtle heat Freshly ground pepper is always best
- Fresh parsley: Bright garnish adds freshness Chop right before serving for optimal taste and color
Step-by-Step Instructions
- Prep the Vegetables:
- Halve or quarter baby potatoes so they’re similar in size for even roasting. Wash and trim green beans. Slice yellow onion into thin wedges for a balance of texture and flavor.
- Mix the Seasonings:
- Combine garlic powder salt Italian seasoning and black pepper in a small bowl. Mixing first ensures the seasoning is even throughout the dish.
- Toss Everything Together:
- In a large mixing bowl add potatoes green beans onion and sausage slices. Drizzle with olive oil and then sprinkle in your seasoning blend. Toss thoroughly so every piece is coated with oil and spices.
- Arrange on Baking Sheet:
- Line a rimmed baking sheet with parchment paper for easy cleanup and to prevent sticking. Spread the mixture out into a single even layer so the vegetables roast instead of steam.
- Roast Until Tender and Caramelized:
- Bake in a preheated 400 degree oven for thirty to forty minutes. Stir once halfway through so everything browns evenly and potatoes become crisp-tender.
- Finish and Serve:
- As soon as the potatoes are fork-tender and the sausage is browned at the edges remove from the oven. Scatter fresh chopped parsley on top and serve hot.

One of my favorite things about this recipe is how the sausage flavors soak into the veggies while roasting. I remember trying a similar dish as a child at my grandmother’s house and I always come back for second helpings when I make it at home.
Storage Tips
Let any leftovers cool then store them in an airtight container in the fridge. The dish keeps well for up to three days. Reheat in a skillet or on a sheet pan in the oven to revive the crispy edges.
Ingredient Substitutions
Switch out the baby potatoes for sweet potatoes or Yukon Golds for a slightly different texture and flavor. If you cannot find andouille or kielbasa try smoked chicken sausage or a plant-based sausage for a lighter option. Baby carrots or bell peppers are great stand-ins if you are short on green beans.
Serving Suggestions
Pair this all-in-one meal with a crisp side salad or warm crusty bread for a classic family table feel. For a lighter summer meal try serving with a dollop of herbed yogurt instead of bread or add a squeeze of lemon just before serving.

Origins and Inspiration
While similar combinations pop up across southern and midwestern kitchens this particular one-pan technique comes from my love of lazy Sunday meals. It reminds me of big gatherings where food comes out piping hot and family gathers around with little fuss on clean-up.
