Ingredients

Scale

Core Ingredients

pounds smoked sausage (beef or turkey), sliced into ½-inch rounds​
2 pounds Yukon gold or red potatoes, diced into uniform chunks​
pounds fresh green beans, trimmed​
2 tablespoons olive oil​
1 teaspoon garlic powder​
1 teaspoon onion powder​
1 teaspoon kosher salt
½ teaspoon black pepper​

Optional Additions

1 cup shredded cheddar or mozzarella cheese​
1 cup sliced mushrooms or red bell pepper strips​
1 teaspoon fresh thyme or rosemary​
½ cup low-sodium broth


Instructions

  • Preheat Oven
    Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish.

  • Prepare Ingredients
    Wash and dice the potatoes into uniform chunks. Slice the sausage into ½-inch rounds. Trim the ends off the green beans.

  • Parboil Potatoes
    Boil or steam the diced potatoes for about 8–10 minutes until just fork-tender. Drain and set aside.

  • Combine Ingredients
    In a large bowl, combine the sausage, parboiled potatoes, and green beans. Drizzle with olive oil, then add garlic powder, onion powder, salt, and pepper. Toss until evenly coated.

  • Assemble Casserole
    Transfer the mixture to the prepared baking dish, spreading it out evenly. If using, add optional ingredients like cheese, mushrooms, bell peppers, herbs, or broth.

  • Bake
    Cover the dish with aluminum foil and bake for 20 minutes. Remove the foil and continue baking for an additional 15–20 minutes, stirring halfway through, until the potatoes are golden and the sausage is browned.

  • Rest and Serve
    Allow the casserole to rest for about 5 minutes before serving. This helps the flavors meld and makes it easier to serve.

Notes

  • Green Beans: For a vibrant color and crisp texture, briefly steam fresh green beans for 2 minutes before adding them to the casserole.

  • Sausage: Using pre-cooked smoked sausage saves time and ensures even cooking.

  • Cheese: Adding cheese during the last 5 minutes of baking creates a deliciously melted topping.

  • Variations: Feel free to customize with different vegetables or spices to suit your taste.
