How to Make Green Bean Casserole Without Canned Soup

- Place the green beans in a steamer pot over boiling water and steam for 8 minutes or until fork tender. Preheat oven to 400°F.

- In a large sauce pot melt 1 tablespoon butter and sauté the chopped onion and 1/4 teaspoon of salt for 4 minutes.

- Remove the onions and set aside in a separate bowl with the panko and parmesan cheese. Toss to evenly combine.

- In the same large sauce pot, melt the remaining 2 tablespoons of butter, add the mushrooms and remaining 1 teaspoon of salt and sauté for 4 minutes. Add the minced garlic and cook for an additional 1 minute.

- Sprinkle 2 tablespoons of flour over the mushrooms and stir for 30 seconds until evenly coated.

- Add the chicken broth and milk, bring to a simmer and cook for 8-10 minutes or until thickened. If you run your spoon through the sauce and it immediately runs back together, continue to reduce.

- Add the beans to the sauce and then pour into a greased 8 x 8 inch baking dish.

- Sprinkle with onion/panko mixture on top, lightly spray with oil and bake for 25 minutes or until the top is golden.

Tips and Tricks
- Make Ahead Version: This casserole is perfect for prepping ahead during a busy holiday week! Make the crispy onion topping and the green bean/mushroom mixture a day in advance, then assemble and bake right before serving.
- Storage: Got leftovers? Store your green bean casserole covered in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through to keep the topping crisp.
- For Extra Crisp Topping: If you love a golden, crunchy finish, broil the casserole for 1–2 minutes at the end of baking. Just keep a close eye so it doesn’t burn!

I make this recipe every year for many years now. It’s delicious. Thank you so much for sharing!
That makes my heart so happy! Glad this one has become a tradition for you 🙂 Thanks for the kind comment!

You could make the green bean mixture and the onion mixture a day ahead of time. Keep them separated, then combine when ready to place in the oven.
How far in advance could I make this?
Simply delicious! Followed recipe exactly and it is soooo good. Thanks, Catherine!

Catherine, I want to try the green bean casserole. I’m adding it to my Thanksgiving meal plan. I have a question: What brand/model is that electric skillet you’re using in the video? I think I could teach my young kids to try cooking if we had something like that. Thank you!
Oops…green beans should have been mushrooms! We love green beans but are not mushroom fans.
No one in our family cares for green beans. Is there a way to make the roux with something else other than mushrooms to give it good flavor?
Love green bean casserole and this one looks soooo creamy 🙂
