Frequently Asked Questions

How do I keep the green beans from getting mushy in the casserole?

The key is to add the green beans partway through the baking time. the green beans are added after the potatoes have roasted for about 20 minutes. This keeps them vibrant, crisp-tender, and prevents overcooking.

Can I make Sausage Green Bean Potato Casserole ahead of time?

Absolutely! You can prep the entire casserole, cover it tightly, and store it in the refrigerator for up to 24 hours before baking. For best results, bring the dish to room temperature for about 20 minutes before placing it in the oven to ensure even cooking.

What type of sausage works best for this recipe?

Smoked sausage is the most common choice for its rich, savory flavor. However, kielbasa, turkey sausage, or even spicy andouille sausage work well depending on your preference. For a lighter option, use chicken or plant-based sausage while still keeping the essence of Sausage Green Bean Potato Casserole intact.

Can I use frozen green beans and potatoes?

Yes, frozen green beans are a convenient substitute. There’s no need to thaw them — just add them during the second baking phase. For potatoes, frozen diced potatoes can work, but keep in mind they may soften more quickly, so monitor baking time to prevent overcooking.
