Step‑by‑Step Instructions for Green Bean and Potato Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step ensures the heat is evenly distributed as you bake your Green Bean and Potato Casserole. While the oven warms up, grease your casserole dish with cooking spray or a light layer of olive oil to prevent the casserole from sticking during baking.
Step 2: Combine the Ingredients
In your greased casserole dish, layer the drained diced potatoes and fresh or frozen green beans. Next, add the creamy Colby cheese and pour in the cream of chicken soup. Using a spatula, gently mix everything together until all the ingredients are well combined, and you’re left with a colorful, creamy mixture ready for baking.
Step 3: Cover and Bake
Carefully cover the casserole dish with aluminum foil, making sure it’s tightly sealed to trap moisture. Place the dish into your preheated oven and bake for 30 minutes. This initial baking process allows the flavors to meld beautifully and the ingredients to soften, setting the stage for a delicious casserole.
Step 4: Uncover and Continue Baking
After the first 30 minutes, carefully remove the foil to let the casserole brown nicely. Bake uncovered for an additional 15 minutes, allowing the top to become bubbly and golden. Keep an eye on it; you want that delightful crispy layer forming while ensuring the insides remain creamy and comforting.
Step 5: Serve the Casserole
Once your Green Bean and Potato Casserole has reached a beautiful golden-brown color, carefully remove it from the oven. Let it cool for a few minutes before serving. Dish up portions of this hearty casserole, and enjoy it hot as a delightful side or main dish perfect for sharing with family and friends.

This Creamy Green Bean and Potato Casserole is ideal for those busy nights when you need a comforting meal on hand. You can easily prepare it up to 24 hours ahead of time by mixing your diced potatoes, green beans, Colby cheese, and cream of chicken soup in the casserole dish, then covering it tightly with plastic wrap or foil and refrigerating. To keep the ingredients fresh and prevent browning, give the potatoes a quick rinse before assembling. When you’re ready to bake, simply remove the casserole from the refrigerator, uncover it, and pop it into a preheated oven following the original baking instructions—no need to adjust the cooking time! Enjoy the ease of having a homemade dinner ready to go with minimal effort!

Green Bean and Potato Casserole Recipe FAQs
What kind of potatoes should I use?
You can use diced potatoes for this recipe, but I recommend fresh potatoes. If you prefer, parboil them for 10-15 minutes before adding them to the casserole. This ensures they cook evenly and result in a soft texture that’s perfect for your dish!
How should I store leftovers from the casserole?
Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Before serving, reheat in the oven or microwave until warmed through. It’s always best to enjoy it while it’s fresh and creamy!
Can I freeze the Green Bean and Potato Casserole?
Absolutely! You can freeze portions of the casserole in airtight containers or freezer bags for up to 2 months. To thaw, place it in the refrigerator overnight, then reheat in the oven at 350°F (175°C). Cover it initially with foil to keep it moist, and uncover the last few minutes for a crispy topping.
What should I do if my casserole is too watery?
If you find your casserole is too watery, the most likely culprit is not draining the potatoes thoroughly or using too much cream of chicken soup. To fix it, you can try adding a bit of cornstarch mixed with water or a handful of breadcrumbs during the cooking process to absorb excess liquid. Ensure your potatoes are well-drained before combining them with the other ingredients for the best texture!
Are there any allergy considerations for this dish?
Yes! This casserole contains cheese and cream of chicken soup, which may not be suitable for those with dairy allergies. For a dairy-free variation, consider using dairy-free cheese and a homemade cream of mushroom soup. Always check labels to ensure any substitutes fit your dietary needs.
