- Garlic (2-3 cloves) – Freshly minced for aromatic flavor.
- Olive Oil (2 tablespoons) – For sautéing and roasting.
- Butter (2 tablespoons) – Adds richness to the dish.
- Chicken Broth (½ cup) – Enhances the flavor and helps with cooking the vegetables.
- Heavy Cream (½ cup) – For a creamy, rich casserole base.

Substitutions and Variations
The great thing about this casserole is its versatility. If you're missing some ingredients or want to switch things up, here are some substitutions and variations to consider:
- Sausage Variations:
- If you want to cut down on fat, use turkey or chicken sausage.
- For extra spice, use hot Italian sausage or chorizo.
- Smoked sausage or kielbasa add a robust, smoky flavor that pairs well with potatoes and green beans.
- Potato Options:
- Russet potatoes are classic, but you can use red or Yukon Gold for a creamier texture.
- For a low-carb option, substitute the potatoes with cauliflower florets.
- Green Beans:
- Fresh green beans are best, but you can use frozen ones to save time.
- Canned green beans work, too, but be sure to drain and rinse them thoroughly.
- Cheese Options:
- If you’re not a fan of cheddar, try using mozzarella, gouda, or Monterey Jack for a different flavor profile.
- To add an extra punch, top with some crumbled feta or blue cheese after baking.
- Vegan Version:
- Use plant-based sausage, dairy-free cheese, and swap heavy cream for coconut milk or a plant-based alternative to create a vegan-friendly casserole.
Step-by-Step Cooking Instructions

This Sausage Green Bean Potato Casserole is easy to assemble and doesn’t require any advanced cooking techniques. Here's how to prepare it:
- Preheat the oven to 375°F (190°C).
- Prepare the sausage:
- Heat a large skillet over medium heat. Add a bit of olive oil and cook the sausage until browned, breaking it into smaller pieces as it cooks.
- Once browned and cooked through, remove the sausage from the skillet and set aside.
- Sauté the vegetables:
- In the same skillet, add some olive oil and butter. Sauté the diced onions until they turn translucent, about 3-4 minutes.
- Add minced garlic and cook for another 1-2 minutes until fragrant.
- Toss in the chopped potatoes and cook for about 5 minutes until they start to soften. Season with salt, pepper, paprika, and Italian seasoning.
- Add green beans:
- Stir the green beans into the mixture, combining them well with the potatoes and onions. If using fresh beans, sauté for an additional 3-4 minutes to soften them slightly.
- Create the sauce:
- Pour in the chicken broth and heavy cream, stirring to combine. Bring to a simmer and cook for 3-4 minutes until the sauce begins to thicken.
- Combine and bake:
- In a large baking dish, layer the sautéed sausage at the bottom. Then, pour the creamy potato and green bean mixture over the sausage.
- Sprinkle the shredded cheddar cheese evenly over the top.
- Cover the dish with foil and bake in the preheated oven for 25-30 minutes.
- Remove the foil for the last 10 minutes to let the cheese get bubbly and golden brown.
- Garnish and serve:
- Once the casserole is out of the oven, let it sit for about 5 minutes. Garnish with freshly chopped parsley or a sprinkle of Parmesan cheese.
Common Mistakes to Avoid
When making Sausage Green Bean Potato Casserole, avoid these common pitfalls to ensure your dish turns out perfect:
- Underseasoning: Potatoes tend to absorb a lot of seasoning, so be generous with salt, pepper, and spices.
- Overcooking the vegetables: The potatoes and green beans should be tender but not mushy. Keep an eye on cooking times.
- Dry Casserole: If the casserole looks dry after baking, you may not have added enough liquid. Be sure to use the full amount of broth and cream.
- Uneven potato cuts: Make sure to cut the potatoes into even-sized pieces so they cook evenly.
