Classic French’s Green Bean Casserole Recipe – Creamy, Crispy, Perfect

Few dishes capture the heart of comfort food quite like Classic French’s Green Bean Casserole. It’s creamy, savory, and irresistibly crispy on top — the kind of recipe that instantly brings back childhood memories of family gatherings and festive dinners. Originally created in the 1950s by Campbell’s Soup Company, this dish has stood the test of time, becoming a must-have side at Thanksgiving tables across America.

Ingredients List

Main Ingredients

• 4 cups (about 1 pound) fresh green beans, trimmed and cut into 1½-inch pieces
  You can also use two 14.5-ounce cans of cut green beans, drained well, or 16 ounces of frozen green beans thawed and patted dry.

• 1 can (10.5 ounces) cream of mushroom soup
  Use low-sodium if preferred, or make a homemade version using mushrooms, butter, flour, and milk.

• ¾ cup milk
  Whole milk gives the creamiest texture, but you can substitute with low-fat or plant-based milk.

• 1 teaspoon soy sauce (optional, for added umami)

• ¼ teaspoon black pepper, freshly ground

• 1½ cups French’s Crispy Fried Onions, divided

• 1 cup shredded cheddar cheese (optional, for a creamier, richer version)

• Salt, to taste (if needed)

Optional Garnish

• Chopped fresh parsley or thyme sprigs for added freshness and color.

Step-by-Step Instructions

Step 1: Prepare the Green Beans

Bring a large pot of water to a rolling boil and add a generous pinch of salt. Drop in the trimmed green beans and blanch for 5–6 minutes, until they are tender yet still slightly crisp.
Immediately drain the beans and transfer them to a bowl of ice water to halt the cooking process. This keeps them bright green and prevents them from turning mushy. After a few minutes, drain again and set aside.
(If using canned beans, simply drain and pat dry to remove excess moisture.)

Step 2: Create the Creamy Sauce

In a large mixing bowl, whisk together the cream of mushroom soup, milk, soy sauce, and black pepper. The mixture should be smooth and velvety. If you prefer a homemade sauce, melt 2 tablespoons of butter in a saucepan, whisk in 2 tablespoons of flour, and cook for 1–2 minutes. Gradually whisk in ¾ cup of milk and ½ cup of vegetable broth, then add 1 cup of sautéed mushrooms for a richer, fresher taste.

Step 3: Combine the Ingredients

Add the blanched green beans to the mushroom sauce mixture, then stir in ½ cup of the crispy onions and half of the shredded cheese (if using). Gently fold everything together so the green beans are evenly coated without breaking.

Step 4: Assemble the Casserole

Lightly grease a 2-quart baking dish. Pour the green bean mixture into the dish and spread it evenly. This ensures even cooking and a smooth, consistent texture throughout.

Step 5: Bake the Base

Preheat your oven to 350°F (175°C) and bake the casserole for 25–30 minutes, until it’s hot and bubbling at the edges. The sauce should thicken slightly and coat the beans evenly.

Step 6: Add the Crispy Topping

Remove the casserole from the oven and carefully sprinkle the remaining crispy onions and cheese (if desired) over the top. Return it to the oven for another 8–10 minutes, or until the onions turn a deep golden brown and the top becomes irresistibly crispy.

Step 7: Rest and Serve

Allow the casserole to rest for about 5 minutes before serving. This helps the sauce settle and thickens the texture slightly. Garnish with chopped parsley or thyme for a fresh, fragrant finish.

For a perfectly balanced holiday table, pair this casserole with roasted turkey, garlic mashed potatoes, and cranberry sauce.

Tips and Substitutions

1. Use Fresh Ingredients When Possible:
Fresh green beans have better texture and flavor than canned. If using frozen, make sure to thaw and drain well to avoid a watery casserole.

2. Keep the Onions Crispy:
Always add the fried onions toward the end of baking. Adding them too early can cause them to soften instead of crisp up.

3. Add a Flavor Boost:
For deeper flavor, sauté 1 clove of minced garlic and a handful of chopped onions in butter before mixing with the soup. A splash of Worcestershire sauce or a dash of smoked paprika can also add richness.

4. Make It Healthier:
Swap regular fried onions for baked or air-fried ones, and use a light cream of mushroom soup or homemade sauce with olive oil instead of butter. You can also add extra vegetables like chopped carrots or peas for fiber and color.

5. Go Dairy-Free or Vegan:
Use unsweetened almond or oat milk and vegan mushroom soup. Nutritional yeast adds a natural cheesy flavor without dairy.

6. Avoid Soggy Texture:
Make sure your beans are fully drained before mixing with the sauce. Excess water can dilute the flavor and prevent the topping from crisping.

7. Add Protein:
Turn this side dish into a main course by adding cooked, shredded chicken, turkey, or crispy bacon. This variation works beautifully for weeknight dinners.

Recipe Variations

1. Cheesy Green Bean Casserole

Add 1½ to 2 cups of shredded cheddar or mozzarella cheese to the sauce before baking. The result is a creamy, indulgent version that feels like a cross between mac and cheese and a vegetable gratin.

2. Mushroom Lover’s Casserole

Sauté 2 cups of fresh sliced mushrooms in butter with garlic and thyme until golden brown, then fold them into the sauce. This intensifies the mushroom flavor and adds meaty texture.

3. Gluten-Free Green Bean Casserole

Choose gluten-free cream of mushroom soup and gluten-free crispy onions. Cornstarch or rice flour can replace wheat flour in homemade sauces.

4. Vegan Variation

Use dairy-free soup, plant-based milk, and vegan fried onions. For extra creaminess, stir in a tablespoon of cashew cream or blended silken tofu.

5. Spicy Kick

Add a pinch of cayenne, red chili flakes, or a few dashes of hot sauce to the mushroom mixture for a gentle, warming heat that contrasts beautifully with the creamy texture.

6. Mediterranean Twist

Replace the mushroom soup with a mixture of Greek yogurt, garlic, lemon juice, and olive oil. Sprinkle with feta cheese and chopped sun-dried tomatoes before baking.

Each of these variations proves how versatile this classic dish can be. For more globally inspired, health-forward recipes that nourish the body as much as they satisfy the palate, you’ll find endless inspiration inside The Encyclopedia of Power Foods.

Common Questions

Can I make French’s Green Bean Casserole ahead of time?
Yes. Assemble the casserole up to 2 days in advance without the onion topping. Cover tightly and refrigerate. When ready to serve, bake as usual and add the topping during the last 10 minutes.

Why did my topping get soggy?
This often happens if the casserole sits too long before baking or if it’s covered while cooling. Always add onions just before finishing in the oven.

Can I use homemade fried onions?
Absolutely. Slice onions thinly, dredge in flour and seasonings, then fry or air-fry until golden. They’re fresher and more flavorful than packaged versions.

Can I double the recipe for a large gathering?
Yes. Simply double all ingredients and bake in a 9×13-inch dish for about 35–40 minutes, adding the onions halfway through.

What can I serve this casserole with besides turkey?
It pairs beautifully with roasted chicken, pork tenderloin, baked salmon, or even as a vegetarian entrée with crusty bread and salad.
