Ingredients List for Sausage Green Bean Potato Casserole
Before diving into the cooking process, it’s important to gather all the ingredients. Here’s what you’ll need for the Sausage Green Bean Potato Casserole:
- 1 lb smoked sausage (or your preferred type of sausage) – Sliced into bite-sized rounds. Smoked sausage brings that distinct savory, slightly smoky flavor to the dish.
- 1 lb fresh green beans – Trimmed and cut into 2-inch pieces. Fresh green beans offer a crisp texture, but you can substitute with frozen if needed.
- 1.5 lbs baby potatoes (red or yellow) – Washed and quartered. Baby potatoes are ideal for roasting, providing a creamy interior with a crispy exterior.
- 2 tablespoons olive oil – For roasting the vegetables and sausage.
- 1 tablespoon garlic powder – Adds a fragrant and rich garlic flavor to the dish.
- 1 tablespoon onion powder – Enhances the savory depth of flavor in the casserole.
- 1 teaspoon smoked paprika – Adds a hint of smoky warmth to the dish.
- Salt and pepper to taste – Essential for balancing the flavors.
- Fresh parsley (optional) – Chopped for garnish, adding a pop of color and freshness.
Substitutions and Variations
One of the best things about the Sausage Green Bean Potato Casserole is how adaptable it is. Here are some common substitutions and variations you can try to make the dish your own:
- Sausage Substitutes: While smoked sausage is a great option for this recipe, you can easily swap it out for other types. Try Italian sausage for a spicier kick, chicken sausage for a lighter option, or kielbasa for a slightly sweeter flavor.
- Potato Alternatives: If you don’t have baby potatoes, Yukon Gold or Russet potatoes work just as well. Just chop them into 1-inch pieces to ensure even cooking. Sweet potatoes can also add a delightful sweetness to balance the savory sausage.
- Vegetable Variations: Add more vegetables to the mix, such as bell peppers, onions, or carrots for added color and nutrition. For a fall twist, try adding cubed butternut squash.
- Cheesy Casserole: To add a rich, cheesy layer, sprinkle shredded cheddar or mozzarella cheese on top during the last 10 minutes of baking.
- Herbs & Spices: Experiment with different herbs like thyme, rosemary, or oregano. For a spicier casserole, add a pinch of red pepper flakes or Cajun seasoning.
Step-by-Step Cooking Instructions

Follow these easy steps to prepare your Sausage Green Bean Potato Casserole. With minimal prep and cooking, you’ll have a delicious dinner ready in no time!
1. Preheat the Oven
Start by preheating your oven to 400°F (200°C). This temperature will help roast the ingredients, allowing the potatoes to become crispy and the sausage to caramelize.
2. Prepare the Ingredients
While the oven heats up, prepare your ingredients:
- Wash and trim the green beans.
- Wash the baby potatoes and cut them into quarters.
- Slice the smoked sausage into bite-sized pieces.
3. Season the Ingredients
In a large mixing bowl, combine the potatoes, green beans, and sausage slices. Drizzle the olive oil over the top, then sprinkle the garlic powder, onion powder, smoked paprika, salt, and pepper. Toss everything together until the ingredients are well-coated in the seasoning.
4. Arrange on a Baking Sheet
Spread the seasoned ingredients evenly onto a large baking sheet. Make sure the potatoes and sausage are spaced out for even roasting. Overcrowding the pan can lead to steaming instead of roasting.
5. Roast in the Oven
Place the baking sheet in the preheated oven and roast for 25-30 minutes, stirring halfway through to ensure even cooking. The casserole is ready when the potatoes are golden and tender, and the sausage is nicely browned.
6. Garnish and Serve
Once the casserole is cooked through, remove it from the oven. If desired, sprinkle with fresh parsley for a bright, fresh finish. Serve warm, and enjoy!

To summarize the process:
- Preheat your oven to 400°F (200°C).
- Wash, trim, and prepare the vegetables and sausage.
- Season the potatoes, sausage, and green beans with olive oil, garlic powder, onion powder, smoked paprika, salt, and pepper.

Common Mistakes to Avoid
While this recipe is simple, a few common mistakes can prevent it from turning out perfectly:
- Overcrowding the baking sheet: When the ingredients are too close together, they steam instead of roast. This can result in soggy potatoes and sausage. Use a large enough sheet pan or roast in batches if needed.
- Skipping the stir: Stirring the ingredients halfway through cooking ensures even browning and helps the potatoes cook evenly.
- Not seasoning enough: Potatoes and green beans can be bland without proper seasoning. Don’t be afraid to add enough salt and pepper to enhance the flavors.
- Under-roasting the potatoes: Ensure the potatoes are fully cooked and have a crispy exterior. If they need more time, give them an additional 5-10 minutes in the oven.
Serving and Presentation Tips
When it comes to serving Sausage Green Bean Potato Casserole, presentation plays a key role. Here’s how to make your dish stand out:
- Family-Style Serving: Serve the casserole directly from the baking sheet for a rustic, family-style presentation. Place it on a wooden board with a serving spoon so guests can help themselves.
- Portioned Plates: For a more formal meal, divide the casserole into individual portions and serve on warm plates. Garnish with fresh parsley for a pop of color.
- Pair with Fresh Sides: Complement the casserole with a light side salad or crusty bread to balance out the rich flavors.
