This one-pan sausage and green beans recipe has been my weeknight lifesaver for years. When I need a comforting meal without the hassle of multiple dishes, this flavorful combination of perfectly roasted sausage, tender green beans, and crispy potatoes always delivers satisfaction with minimal effort.
I first made this recipe when my in-laws showed up unexpectedly for dinner. The meal came together so quickly and impressed everyone so much that it's now our go-to entertaining dish when we want something delicious without spending all day in the kitchen.
Ingredients

- Garlic powder: provides aromatic depth without the risk of burning that fresh garlic has
- Salt: enhances all the flavors use kosher salt for better flavor distribution
- Italian seasoning blend: a timesaving mixture that adds complexity without multiple spice jars
- Black pepper: adds necessary warmth and subtle heat
- Fresh parsley: the final fresh element that brightens the entire dish
How To Make One Pan Sausage Green Beans
- Prepare the ingredients:
- Cut potatoes into evenly sized pieces to ensure they cook at the same rate. For average baby potatoes, halves work well, but larger ones may need quartering. Trim green beans by snapping off the tough ends or using a knife to cut them. Slice the onion into wedges thick enough to withstand roasting without burning. Cut the sausage on a diagonal bias which increases surface area for better browning and creates more visually appealing pieces.
- Create the seasoning mixture:
- Combine all the dry seasonings in a small bowl before adding to the vegetables. This extra step ensures even distribution of flavors throughout the dish rather than having pockets of certain spices. The blend should be fragrant and well mixed.
- Coat everything thoroughly:
- In a large mixing bowl, toss all ingredients with olive oil first to create a thin coating that helps the seasonings adhere. Add the spice mixture next, using your hands or wooden spoons to turn the ingredients repeatedly until every piece has visible seasoning. This thorough coating is crucial for developing flavor during roasting.
- Arrange for optimal cooking:
- Spread everything in a single layer on your parchment-lined baking sheet, ensuring no pieces are stacked on top of each other. Space between items allows hot air to circulate, creating the caramelized edges that deliver the best flavor. If overcrowded, the ingredients will steam rather than roast.
- Monitor the cooking process:
- At the halfway point around 15 minutes, open the oven and stir everything with a spatula. Redistribute any pieces that are browning too quickly to the center and move less-browned pieces to the edges where heat is more intense. This adjustment ensures everything finishes cooking at the same time.
- Finish with fresh elements:
- The chopped parsley added at the end provides more than just visual appeal it adds a bright, herbaceous counterpoint to the rich, savory flavors that developed during roasting. Add it just before serving so it maintains its vibrant color and fresh flavor.
My favorite part of this dish is how the sausage fat renders during roasting, coating the vegetables with its savory flavor. I discovered this happy accident when I first made the recipe with particularly fatty kielbasa, and now I specifically look for sausages with a higher fat content to enhance this effect. My husband always reaches for the crispy onion bits first, claiming they taste like savory candy.
Make-Ahead Options
You can prep this entire dish up to 24 hours before cooking. Simply prepare all ingredients, toss with oil and seasonings, then store in an airtight container in the refrigerator. When ready to cook, spread on your sheet pan and add about 5 minutes to the cooking time since the ingredients will be cold. This prep-ahead approach makes it perfect for busy weeknights when you know time will be limited.

Variation Ideas
This recipe template works beautifully with numerous variations. Try sweet Italian sausage with bell peppers and zucchini in summer, or swap in chorizo with sweet potatoes and brussels sprouts for a fall version. Chicken sausage makes a lighter option that pairs wonderfully with asparagus and red potatoes. The key is maintaining similar cooking times for your chosen vegetables or staggering the addition of quicker-cooking items halfway through.
Serving Suggestions
While this dish stands perfectly well on its own, I sometimes serve it with a simple side to round out the meal. A green salad with a tangy vinaigrette provides a nice contrast to the rich roasted flavors. For heartier appetites, crusty bread for soaking up the flavorful juices from the pan works beautifully. During summer months, we enjoy this with a cold glass of crisp white wine or lemonade for the kids.
Storage Instructions
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F oven for 10 minutes to maintain the crispy texture, or microwave for 1-2 minutes if you're in a hurry. I often make a double batch specifically for meal prep lunches throughout the week. The flavors actually improve after a day in the refrigerator as they have time to meld together.

Recipe FAQs
- → Can I use different types of sausage?
Absolutely! While the dish calls for pre-cooked andouille or kielbasa, you can substitute with Italian sausage, chicken sausage, or even turkey sausage. If using raw sausage, ensure it reaches an internal temperature of 74°C (165°F) before serving.
- → How can I make this dish spicier?
To add heat, incorporate red pepper flakes into your seasoning mix, use a spicy variety of andouille sausage, or add sliced jalapeños to the vegetable mixture before roasting. You could also serve with hot sauce on the side.
- → Can I prepare this ahead of time?
Yes! You can prep all ingredients and store them separately in the refrigerator for up to 24 hours. You can also toss everything with oil and seasonings, then refrigerate in a sealed container for up to 8 hours before baking. Add 5 minutes to the cooking time if starting from cold.
- → What can I substitute for green beans?
Asparagus, broccoli florets, Brussels sprouts, or bell peppers work wonderfully as alternatives. Adjust cooking times accordingly as some vegetables cook faster than green beans. For vegetables that cook quickly, consider adding them halfway through the roasting time.
- → Is this dish gluten-free?
The basic ingredients are naturally gluten-free, but always check your sausage labels as some varieties contain fillers with gluten. The seasonings should be gluten-free, but verify your Italian seasoning blend doesn't contain any gluten-based additives.
- → What sides pair well with this meal?
While this is a complete meal on its own, you could serve it with crusty bread, a simple green salad, or a side of applesauce for a complementary sweet element. For a more substantial meal, consider serving over rice or with cornbread.
