Step-by-Step Overview
Making Green Bean Casserole is a straightforward process that anyone can master. You’ll start by preheating the oven and preparing your ingredients—trimming and blanching the green beans and sautéing mushrooms if you choose to include them. Next, you’ll mix the creamy soup with milk and seasonings, then combine everything together before transferring it to the oven for baking.
What You’ll Need
Here’s a list of the ingredients you’ll need to create this classic dish:
- 4 cups fresh green beans, trimmed and blanched
- 1 can (10.5 oz) cream of mushroom soup
- 1/2 cup milk
- 1 cup French fried onions, divided
- 1/2 cup sliced mushrooms (optional)
- 1 tablespoon butter (optional, for sautéing mushrooms)
- 1/2 teaspoon garlic powder (optional)
- Salt and pepper to taste
Feel free to swap fresh green beans for frozen, but make sure to check their texture, as they can be softer once cooked. If you’re looking for a lighter option, consider using a low-fat cream of mushroom soup.

Directions to Follow
- Preheat your oven to 350°F (175°C).
- If using mushrooms, heat butter in a pan over medium heat and sauté them until they are tender.
- In a large mixing bowl, whisk together the cream of mushroom soup, milk, garlic powder, salt, and pepper until the mix is smooth.
- Gently fold in the blanched green beans and the sautéed mushrooms, ensuring everything is well coated.
- Pour the mixture evenly into a casserole dish.
- Bake for 20-25 minutes, until hot and bubbly.
- Stir in half of the French fried onions, sprinkle the remaining onions on top, and return to the oven for an additional 5-7 minutes, until the onions are golden brown.
Best Ways to Enjoy It
This Green Bean Casserole pairs beautifully with a variety of main dishes. Serve it alongside roasted turkey for Thanksgiving, grilled chicken for a summer barbecue, or even as a centerpiece for a vegetarian meal. For a fun twist, consider adding a sprinkle of freshly grated Parmesan cheese or a squeeze of lemon juice over the top before serving.
How to Store
To keep your leftovers fresh, store any uneaten Green Bean Casserole in an airtight container in the refrigerator. It will stay good for about 3-4 days. If you want to reheat the casserole, simply place it in the oven at 350°F (175°C) until warmed through, or cover it and microwave individual portions until hot. Avoid reheating multiple times, as this can affect the texture of the green beans.
Helpful Cooking Tips
- Make sure to blanch the green beans before adding them to the casserole to preserve their bright color and crispness.
- If you prefer a more intense flavor, try sautéing the mushrooms with a clove or two of minced garlic.
- For crunchier onions, consider adding them during the last few minutes of baking; this will help maintain their texture.
Recipe Variations
Get creative with this Green Bean Casserole! You can easily modify the recipe by incorporating different ingredients. Consider adding shredded cheese for a cheesy twist, or a handful of chopped walnuts for an added crunch. If you want to make it dairy-free, try substituting the cream of mushroom soup with a vegan alternative and using plant-based milk.
