Cajun Sheet Pan Sausage and Vegetables
This Cajun sheet pan dinner puts sausage, potatoes, and vegetables on one tray. Seven ingredients cover the whole recipe, including the oil and seasoning. I chop everything after work before changing out of my office clothes. The oven handles the cooking while the sausage seasons the surrounding vegetables.
Why This Works

Andouille brings smoky flavor without requiring a separate sauce. Cajun seasoning distributes spices across the potatoes, peppers, onion, and green beans. Olive oil coats the cut surfaces and helps the vegetables roast. The potatoes add substance, so another starch isn’t necessary for serving.
The vegetables offer different textures while sharing the same cooking temperature. Onion and pepper soften, while green beans retain more bite. The supplied nutrition lists 356 calories and 14g protein per serving. Divide the finished pan evenly into six portions to match that yield.
How It Comes Together
Allow 15 minutes prep and 30 minutes cooking. The listed total is 45 minutes for six servings. Most preparation involves cutting the potatoes and vegetables to the specified sizes. Slice the sausage, then combine everything in a large bowl.
Toss the mixture with olive oil and Cajun seasoning before spreading it out. Check that potatoes and vegetables receive seasoning instead of leaving it underneath. Roast until the potatoes are tender when pierced with a fork. Larger potato pieces may need longer than the stated cooking time.
What You Need

Check the Andouille package to confirm whether the sausage is fully cooked. Fully cooked sausage is the straightforward choice for this short roasting method. If using raw sausage, follow its package cooking requirements and verify doneness. Cajun seasoning blends also vary in salt and heat.
- 1 pound white potatoes, cut into 3/4-inch pieces
- 12 ounces Andouille sausage, sliced into rounds
- 1 small yellow onion, cut into 1-inch pieces
- 1 yellow bell pepper, cut into 1-inch pieces
- 12 ounces fresh green beans, trimmed and cut in half
- 1/4 cup extra virgin olive oil
- 1 tablespoon Cajun seasoning
How to Make It

Use a large, rimmed sheet pan to contain the oil and cooking juices. Spread the mixture across the surface rather than piling it in the center. Keep potato pieces close to the specified size for more consistent cooking.
- Preheat the oven to 400°F (200°C).
- In a large mixing bowl, combine the potatoes, sausage, onion, bell pepper, and green beans. Add the olive oil and Cajun seasoning, then toss until evenly coated.
- Spread the seasoned mixture out in an even layer onto a sheet pan.
- Bake for about 30 minutes, or until the potatoes are fork-tender and the vegetables are roasted.
Test several potato pieces before removing the pan from the oven. A fork should pass through their centers without firm resistance. Check pieces from different areas because ovens don’t always heat evenly. Continue roasting briefly if any larger pieces remain firm.
How to Serve It
Serve directly from the pan for the shortest route to dinner. Divide the sausage rounds and vegetables evenly among six plates or bowls. Spoon any remaining seasoned juices over the potatoes. A simple green salad adds a cool contrast to the warm spices.
Rice works alongside the mixture when you want a larger meal. Start it early enough to finish while the sheet pan roasts. Bread is another option for collecting the seasoned juices. These additional sides aren’t included in the supplied nutrition values.
Leftovers and Storage
Refrigerate for up to 4 days at 40°F or below. Divide leftovers into shallow, covered containers within 2 hours of cooking. Reduce that window to 1 hour when surrounding temperatures exceed 90°F. Store salad or bread separately to preserve their texture.
Place one portion in a microwave-safe dish and cover loosely. Heat for 1 minute, stir, then continue in 30-second intervals. Check several spots reach 165°F, including the sausage and potato centers. Microwaving softens the roasted edges but keeps reheating straightforward.
For drier edges, spread leftovers on a sheet pan instead. Reheat at 375°F for 10 minutes, then check the centers. Continue in 3-minute intervals until everything reaches 165°F. Avoid repeatedly reheating the entire batch when you only need one portion.
Quick Notes
Give the mixture room so moisture can escape during roasting. Crowding encourages steaming and limits browned surfaces. If your pan is small, divide between two pans and monitor both.
- Cut potatoes into the listed 3/4-inch pieces so their centers cook on schedule.
- Avoid adding extra salt automatically; sausage and Cajun seasoning may already supply plenty.
- Compare sausage prices by weight rather than package price alone.
- Buy trimmed fresh green beans to reduce preparation time.
- Dry washed vegetables before tossing so excess water doesn’t collect on the pan.
- Replace yellow bell pepper with red bell pepper using the same piece size.
Easy Swaps
These optional substitutions change the original recipe listed above. Keep quantities and cut sizes similar when replacing vegetables. Different sausages and seasonings can change the supplied nutrition values.
- Use fully cooked chicken Andouille instead of pork Andouille for a poultry variation.
- Replace white potatoes with equal weight red potatoes cut into 3/4-inch pieces.
- Choose red or orange bell pepper instead of yellow.
- Use a mild Cajun seasoning blend if your usual blend tastes too hot.

Common Questions
Do I need to boil the potatoes first?
No, the potatoes go onto the pan raw. Cutting them to the specified size helps them finish with the vegetables. Check tenderness before serving rather than relying only on the timer.
How spicy is this dinner?
Heat depends on both the Andouille and the Cajun seasoning. Check their labels when choosing ingredients. A milder sausage and seasoning blend will produce a gentler result.
Can I prepare the vegetables ahead?
Chop the onion, pepper, and beans ahead and refrigerate in covered containers. Cut the potatoes closer to cooking to avoid exposed surfaces browning. Combine with the oil and seasoning when ready to roast.
Keep the potato pieces small and spread everything evenly. Check tenderness before taking the pan out. Portion leftovers promptly for another meal.
