Green Bean Casserole (From Scratch)

It’s difficult to imagine any holiday table without a Creamy Green Bean Casserole (from scratch) with a crunchy, crisp topping. Green Bean Casserole is a classic Thanksgiving side dish and this one is made entirely from scratch and uses a homemade cream of mushroom soup. P.S. It can be made 2 days ahead!

There are a handful of sides that consistently show up at our holiday table and Green Beans are always on the menu! We love serving Green Bean Casserole with Mashed Potatoes, Sweet Potato Casserole, and Roasted Brussels Sprouts all paired with a stunning Prime Rib Roast or Juicy Roast Turkey for the ultimate feast!

Homemade Green Bean Casserole:

This recipe is a staple at Thanksgiving dinner and the holiday itself. Everyone loves a classic green bean casserole and this one is made from fresh real ingredients: Green beans in a creamy mushroom sauce baked under a crisp bread crumb and cheese topping.

What is Green Bean Casserole?

This traditional green bean casserole is essentially a green bean gratin. It was invented in the US by Dorcas Reilly in 1955 who developed it with Campbell’s cream of mushroom soup. This green beans casserole is baked in a homemade cream of mushroom soup and there is nothing quite like homemade! The green beans are more vibrant and the sauce is so flavorful.

The Best Green Bean Casserole Topping:

Rather than using the deep-fried canned onion rings, this recipe has a crisp and flavorful parmesan garlic crust. The contrast between the creamy beans and the crunchy savory crumb topping is delicious.

Making a green bean casserole from scratch is really easy and so much better than canned beans cooked in canned cream of mushroom soup and topped with pre-made deep-fried onions. You will feel so good about serving this to the people you love!

How to Make Green Bean Casserole from Scratch:

Using fresh green beans makes the beans extra sweet, tender, and vibrant. You can’t match that same texture or flavor with beans that come out of a can. To make green bean casserole with fresh green beans:

  • Trim and blanch the beans for 5 minutes for firmer beans or 8 minutes if you prefer softer beans
  • Make the mushroom sauce and combine with green beans
  • Top with the Parmesan herb and garlic breadcrumbs
  • Bake immediately or store in the fridge to bake on the day of the feast

Can You Make Green Bean Casserole Ahead?

During the busyness of the holidays, it’s wonderful to have some make-ahead recipes up your sleeve. You can make this green bean casserole recipe up to 2 days ahead, covered and refrigerated until ready to bake. If baking at a later date, top with the Parmesan breadcrumb mixture immediately before baking to ensure a crisp topping.

If I could describe this green bean casserole, I would say it tastes just like the original but better. The homemade mushroom sauce still holds the same savory punch of Campbell’s cream of mushroom soup but tastes more wholesome, and therefore infinitely more delicious.


Green Bean Casserole (from Scratch)

Creamy green bean casserole recipe made from scratch with homemade cream of mushroom soup, topped with parmesan garlic and herb breadcrumbs.

For the Green Bean Casserole

  • 1 lb green beans trimmed
  • 1 Tbsp butter
  • 1 Tbsp olive oil
  • 8 oz mushrooms (cremini, baby Bella, or white)
  • 1 medium onion chopped
  • 2 cloves garlic
  • 2 Tbsp all-purpose flour
  • 1/2 cup chicken or vegetable stock
  • 1 cup heavy whipping cream
  • 1 Tbsp Worcestershire sauce
  • 1 Tbsp soy sauce
  • salt to taste
  • black pepper to taste

For the Parmesan Herb and Garlic Breadcrumbs

  • 1/2 cup breadcrumbs
  • 1/3 cup parmesan cheese
  • 1/4 tsp garlic powder (or 1 tsp garlic flakes)
  • 1 tsp dried parsley
  1. Preheat Oven to 375˚F. Set a large pot with water over high heat and bring to a boil then add trimmed green beans. Cook/blanch them for 5 minutes for firmer beans or 8 minutes for softer beans. Drain and set aside. 

  2. Meanwhile, Place a large pan over medium/high heat and add 1 Tbsp butter and 1 Tbsp oil, then add sliced mushrooms with a pinch of salt and pepper. Saute until the mushroom liquid has evaporated and mushrooms are golden.

  3. Move mushrooms to one side of the pan and add chopped onion. Saute onions over low heat for a couple of minutes then stir them together with mushrooms and saute until onions are soft (6-8 min). Add minced garlic and cook for 30 seconds longer while stirring. 

  4. Add 2 Tbsp flour and stir until the flour turns into a paste. Continue cooking 1-2 minutes, stirring constantly until it smells slightly nutty, being careful not to burn the mixture.

  5. Add the 1/2 cup chicken stock and bring to a boil over medium heat, stirring constantly and scraping the bottom of the pan with a spatula. Add 1 cup heavy cream, 1 Tbsp Worcestershire sauce, 1 Tbsp soy sauce and cook over low until sauce has a creamy and gravy-like consistency (it thickens more as it bakes). Season with salt to taste.

  6. Add blanched green beans to the mushroom sauce and stir to combine then transfer to a casserole dish. 

  7. In a separate bowl, combine 1/2 cup breadcrumbs, 1/3 cup parmesan cheese, 1/4 tsp garlic powder and 1 tsp dried parsley. Sprinkle over the green bean casserole. Bake uncovered at 375 F for 20 minutes then broil for 2-3 minutes until topping is golden.
