Ingredients

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 1.5-quart or 9x9-inch baking dish.
  2. If using fresh green beans: Bring a large pot of salted water to a boil. Add the trimmed green beans and cook (blanch) for about 5 minutes until they are crisp-tender and bright green. Immediately drain them and plunge them into a bowl of ice water to stop the cooking. Drain well and set aside. This keeps them from getting mushy.
  3. If using canned green beans: Simply drain the beans well.
  4. Classic Method: In a large bowl, whisk together the condensed cream of mushroom soup, milk, soy sauce, and black pepper until smooth.
  5. From-Scratch Method: Heat olive oil in a skillet over medium heat. Add the sliced mushrooms and cook until softened, about 5-7 minutes. Stir in the minced garlic and cook for another minute. Sprinkle the flour over the mushrooms and stir for one minute to cook off the raw flour taste. Slowly whisk in the milk and vegetable broth until smooth. Simmer, stirring often, until the sauce thickens, about 5-8 minutes. Season with salt and pepper.
  6. In your prepared baking dish (or the bowl you mixed in), combine the blanched or canned green beans, the mushroom sauce, and â…” cup of the french fried onions. Stir everything together until the green beans are fully coated.
  7. Spread the mixture evenly in the baking dish. Bake, uncovered, for 25 minutes, or until the casserole is hot and bubbly around the edges.
  8. Remove the casserole from the oven and sprinkle the remaining â…” cup of french fried onions evenly over the top. Return it to the oven and bake for another 5 minutes, just until the onions are golden brown and extra crispy. Let it rest for a few minutes before serving.

Note

  • Make-Ahead Plan: You can assemble the casserole (without the final onion topping) up to 24 hours in advance. Cover and refrigerate. When ready to bake, you may need to add 5-10 minutes to the initial baking time. Add the top layer of onions at the end as directed.
  • Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or in the oven at 350°F until warmed through.
  • Add a Cheesy Twist: For an extra layer of flavor, stir in ½ cup of shredded cheddar or Gruyère cheese with the green beans and sauce.
  • Spice it Up: Add a pinch of cayenne pepper or a dash of hot sauce to the mushroom sauce for a little kick.

Frequently Asked Questions

Expand All:

Can I make this casserole vegan?

Yes! Use the from-scratch sauce method with plant-based milk (like unsweetened almond or oat milk) and vegetable broth. Ensure your french fried onions are vegan, or make your own crispy onions by thinly slicing an onion, tossing it in flour, and pan-frying until golden.

Can I use frozen green beans?

Absolutely. Thaw about 20 ounces of frozen green beans completely and pat them dry to remove excess moisture before adding them to the sauce. This prevents a watery casserole. There's no need to blanch them first.

What can I substitute for cream of mushroom soup?

Besides the from-scratch recipe above, you can use other condensed "cream of" soups like cream of celery or cream of chicken for a different flavor profile. A condensed cheddar cheese soup also works for a cheesier version.

How do I prevent a soggy casserole?

The key is to manage moisture. If using fresh beans, blanching and shocking them in ice water is crucial. If using canned or frozen, make sure they are drained and patted very dry. The from-scratch sauce also gives you more control over the thickness.
