Ingredients Needed to Make Fresh Green Bean Casserole with Homemade Cream of Mushroom Soup
- 3 lbs fresh green beans (trimmed and washed)
- 6 tbsp butter (divided for sautéing and the roux)
- 24 oz mushrooms (finely diced for the best texture)
- 1/3 cup flour (all-purpose works perfectly)
- 1 cup sherry (adds a wonderful depth of flavor)
- 1 cup chicken broth (use a high-quality stock for better results)
- 2 cups half and half (for that signature creaminess)
- 1 1/2 cups crispy fried onions (classic store-bought style)
- 1 tsp dried thyme
- 1 tsp black pepper
- Salt to taste
Instructions to Make Fresh Green Bean Casserole with Homemade Cream of Mushroom Soup – Step by Step
Step 1: Start by preheating your oven to 350 degrees. While that warms up, trim your fresh green beans into manageable 1.5-inch pieces. Bring a large pot of salted water to a rolling boil and blanch the beans for 5 to 7 minutes until they are tender-crisp. Immediately drain and plunge them into an ice-water bath to stop the cooking and lock in that gorgeous, bright green color.
Step 2: In your favorite cast iron skillet or a large heavy-bottomed pan, melt 3 tablespoons of butter over medium-high heat. Add your diced mushrooms and let them sit undisturbed for a few minutes to develop a beautiful brown sear. Sauté them until they are golden and fragrant, then set them aside and repeat the process with the remaining butter and mushrooms. This extra effort ensures your sauce has deep, meaty flavor.
Step 3: Return all the cooked mushrooms to your pan and sprinkle in the flour, stirring constantly for about a minute to cook out that raw flour taste. Splash in the sherry and use a wooden spoon to scrape up all those delicious, flavorful brown bits from the bottom of the pan. Slowly pour in the chicken broth and half-and-half, whisking continuously to ensure the sauce stays silky and lump-free.
Step 4: Season the sauce with the dried thyme, black pepper, and salt. Let the mixture simmer gently for a few minutes until it thickens into a rich gravy. Tilt the pan slightly to pool the sauce and pulse it with an immersion blender to achieve a semi-smooth, creamy texture while leaving a few mushroom chunks for heartiness. If you do not have an immersion blender, a quick whirl in a food processor does the trick.
Step 5: Fold the blanched green beans into the creamy mushroom sauce until every bean is beautifully coated. If your skillet is oven-safe, you can leave it right there; otherwise, transfer the mixture into a 9×13 baking dish. Scatter the crispy fried onions evenly over the top and bake for 35 to 40 minutes, or until you see bubbly, golden edges that look absolutely irresistible.
Chef’s Tips for a Perfect Result
- Always blanch your beans in heavily salted water to season them from the inside out.
- Do not skip the ice bath; it is the only way to keep the beans from turning into a mushy, olive-drab mess.
- Use room-temperature half-and-half to prevent the sauce from breaking or curdling when it hits the hot pan.
- Make sure to scrape the bottom of your skillet thoroughly when adding the sherry; that is where the most intense mushroom flavor lives.
Variations and Substitutions
- Vegetarian Option: Simply swap the chicken broth for a rich vegetable stock or mushroom-based broth to keep the flavor profile deep and savory.
- Gluten-Free Alternative: Substitute the all-purpose flour with a 1:1 gluten-free flour blend, which works beautifully as a thickener without altering the final texture.
- Herb Refresh: Feel free to swap the dried thyme for fresh rosemary or sage if you want a more aromatic, woodsy profile during the winter months.
How to Serve and Pair
This casserole is the ultimate partner for roasted turkey, glazed carrots, or creamy mashed potatoes. Serve it in the original cast iron skillet for a rustic, cozy feel that says you spent all day in the kitchen. For a formal dinner, transfer it to a ceramic serving dish and garnish with a few sprigs of fresh parsley or fried shallots for an extra pop of color and texture.
Storage and Reheating
Refrigerator
Store leftovers in an airtight glass container for up to 3 days. The flavors actually continue to meld and get better the next day, making this a perfect leftover lunch option.
Freezer
While you can freeze this casserole, the texture of the green beans may soften slightly. To freeze, store in a freezer-safe container for up to one month, but wait to add the fried onion topping until the final baking stage.
Reheating
Reheat in a 350-degree oven covered with foil for about 20 minutes until heated through, then remove the foil and add fresh crispy onions for the final 5 minutes of baking to restore the crunch.

Frequently Asked Questions (FAQ)
Can I use canned green beans instead of fresh?
While fresh is best for texture, you can use high-quality canned beans, but make sure to drain them extremely well to prevent a watery sauce. Adjust your salt intake, as canned beans often have a much higher sodium content than fresh.
How do I know when the casserole is fully baked?
The casserole is finished when the sauce is bubbling vigorously around the edges of the dish and the topping is a deep golden brown. A quick poke with a knife into the center should reveal tender, not mushy, green beans.
Why is my sauce lumpy?
A lumpy sauce usually happens if the liquid is added too quickly or not whisked vigorously enough during the initial stages. Use an immersion blender to smooth out any small clumps, and next time, remember to add your liquid in a slow, steady stream while whisking.
Can I assemble this the night before?
Yes, you can fully assemble the casserole, skip the fried onions, cover it tightly, and keep it in the fridge for up to 24 hours. Let it sit on the counter for 20 minutes before baking to take the chill off, and add the onions right before it goes into the oven.
How can I customize this for a brunch menu?
Add some crumbled goat cheese or crispy sautéed shallots to the mixture for an elegant twist that pairs beautifully with scrambled eggs and fresh sourdough toast. The creaminess of the sauce complements savory breakfast items perfectly.

Making a fresh green bean casserole with homemade cream of mushroom soup is a game-changing experience that breathes new life into a holiday classic.

Ingredients
3 lbs fresh green beans, trimmed and washed
6 tbsp butter, divided
24 oz fresh mushrooms, finely diced
1/3 cup all-purpose flour
1 cup vegetable broth (non-alcoholic substitute for sherry)
1 cup chicken stock
2 cups half and half
1 1/2 cups crispy fried onions
1 tsp dried thyme
Salt and black pepper to taste
Instructions
Preheat your oven to 375°F (190°C).
Blanch the green beans in boiling salted water for 3-4 minutes until bright green and crisp-tender, then drain and set aside.
In a large skillet, melt 3 tablespoons of butter over medium-high heat and sauté the mushrooms until browned and moisture has evaporated.
In a separate saucepan, melt the remaining butter and whisk in the flour to create a roux; cook for 1 minute.
Slowly whisk in the vegetable broth and chicken stock, then stir in the half and half until the sauce thickens.
Stir the sautéed mushrooms and dried thyme into the sauce, seasoning with salt and pepper.
Combine the blanched beans with the mushroom cream sauce in a baking dish.
Bake for 20-25 minutes until bubbling.
Top with crispy fried onions and bake for an additional 5 minutes until golden.
Notes
You can assemble the casserole ahead of time and store it in the refrigerator before baking. Add the fried onions just before the final 5 minutes of baking to ensure they remain perfectly crispy. If using fresh thyme, use 1 tablespoon instead of 1 teaspoon of dried.
