Ingredients You’ll Need
· 1 1/2 lbs sausage (kielbasa or smoked sausage), sliced 1/4 inch thick
· 2 lbs baby creamer potatoes, washed and sliced in half
· 2 (15 oz) cans green beans, drained
· 1/8 cup vegetable oil
· 1/4 cup butter, melted
· 1 teaspoon garlic powder
· 1/2 teaspoon onion powder
· 1/2 teaspoon black pepper
· 1/2 teaspoon salt (or to taste, depending on sausage saltiness)
· Optional: 1 small onion, sliced; 1 teaspoon paprika or Italian seasoning
Note: For a lower carb option, use turnips or cauliflower instead of potatoes. For a gluten-free version, ensure sausage is certified gluten-free.
Step-by-Step Instructions
- Preheat Oven: Preheat your oven to 400°F (200°C). Lightly grease a 9×13 inch baking dish or large rimmed sheet pan.
- Prep Ingredients: Slice sausage into 1/4-inch rounds. Wash baby potatoes and cut any larger ones in half so they are roughly equal in size. Drain canned green beans well.
- Season the Potatoes: In a large bowl, toss halved potatoes with vegetable oil, garlic powder, onion powder, black pepper, and salt. Mix until evenly coated.
- Combine Everything: Add sliced sausage and drained green beans to the bowl with potatoes. Pour melted butter over the top and gently toss everything together until well mixed.
- Transfer to Baking Dish: Spread the mixture evenly into the prepared baking dish or sheet pan in a single layer. This helps the potatoes roast and the sausage caramelize.
- Bake: Bake uncovered for 35-45 minutes, stirring once halfway through, until potatoes are fork-tender and sausage is nicely browned. If you like extra crispy edges, broil for the last 2-3 minutes.
- Rest and Serve: Remove from oven and let rest for 5 minutes. Garnish with fresh parsley if desired. Serve hot as a complete meal.
Tips for the Best Sausage Green Bean Potato Casserole
· Use Smoked Sausage: Kielbasa or andouille adds deep, smoky flavor. Turkey sausage works for a lighter option.
· Cut Potatoes Uniformly: This ensures even cooking. Baby creamer potatoes are ideal because they cook quickly and stay tender.
· Fresh Green Beans? If using fresh, blanch them for 3-4 minutes first, or add them raw but increase baking time slightly and cover with foil for the first 15 minutes.
· Add Extra Veggies: Sliced bell peppers, mushrooms, or zucchini can be added for more nutrition.
· Make it Cheesy: Sprinkle 1 cup shredded cheddar cheese over the top during the last 10 minutes of baking for a cheesy casserole twist.
· Crockpot Version: Combine all ingredients in a slow cooker and cook on LOW for 4-5 hours or HIGH for 2-3 hours until potatoes are tender.
Frequently Asked Questions
Can I use fresh green beans instead of canned?
Yes! Use about 1 pound of fresh green beans, trimmed and cut into 2-inch pieces. Blanch them in boiling water for 3 minutes, then drain and add to the casserole. Or add them raw and cover the dish with foil for the first 15 minutes of baking, then remove foil to finish.
What kind of sausage works best?
Smoked sausage like kielbasa, andouille, or beef sausage is classic. You can also use Italian sausage (remove from casing and crumble) or chicken apple sausage for a different flavor. Pre-cooked sausage is easiest.
Is this casserole gluten-free?
It can be. Potatoes, green beans, and most sausages are naturally gluten-free. Always check the sausage label for hidden gluten fillers. Use a gluten-free certified brand if needed.
Can I make this ahead of time?
Yes. Assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. When ready to bake, let it sit at room temperature for 15 minutes, then bake as directed, adding 5-10 extra minutes since it starts cold.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven. You can also freeze portions for up to 2 months – thaw overnight and reheat.
What to serve with this casserole?
It’s a complete meal on its own, but a simple side salad or crusty bread pairs nicely. For extra veggies, steamed broccoli or roasted carrots work well.
