How to make green bean casserole (without canned soup)

Some may argue that it’s not really a “classic” green bean casserole if there’s no canned cream of mushroom soup, but I would argue that they’ve never tasted a true green bean casserole made from scratch!

“I had never made green bean casserole before, and neither had my family. I made this for them and it was such a big hit. We all loved it! I was glad it was easy to make!!” – Gabriela

Tips for making the best green bean casserole

  1. Make a smoother soup. If you prefer not to have sliced mushrooms with the green beans, you can blend the soup to make it smooth before adding to the green beans or you can mince the mushrooms smaller.
  2. Blanche the green beans. Add them to boiling water and once tender, place them into an ice bath. This will stop them from cooking so that they aren’t mushy and it will help them to remain a bright green color.
  3. Make it gluten-free. You can use gluten-free panko breadcrumbs for the topping and use tamari sauce instead of soy sauce.
  4. Make the homemade mushroom soup ahead of time. You can make the soup up to 4 days ahead of time and keep it covered in the fridge. Don’t add it to the green beans until you are ready to bake the casserole so that they stay firm.

What to serve with green bean casserole

This healthy green bean casserole is the perfect side to serve up for Thanksgiving and the holidays, along with your other seasonal favorite recipes. Try them with:

How to store & reheat green bean casserole

Once your green bean casserole has cooled down to room temperature, transfer any leftovers to an airtight container or cover the baking dish tightly with foil or plastic wrap. Refrigerate it within 2 hours of baking.

How long will green bean casserole last in the fridge? When stored properly fresh green bean casserole can last in the refrigerator for about 3 to 4 days. 

Can I freeze leftover fresh green bean casserole? Prepare your leftovers as you would if storing in the refrigerator. Store your casserole in a freezer safe container. Consider portioning into individual servings. Store in the freezer for 2 to 3 months for the best quality.

Reheating leftover green bean casserole: If frozen, allow your casserole to thaw overnight in the fridge before reheating. Once thawed, microwave smaller portions, or bake larger portions until heated through. 

Frequently asked questions

Can you make it vegan?

You can make the mushroom soup with a plant based milk instead of dairy. Use one with a neutral flavor such as unsweetened almond, oat or soy.

Can you use frozen green beans?

We prefer to make this casserole with fresh green beans, but you can use frozen if you have those to hand. You’ll just need to blanch them in boiling water for an extra minute.

How do I prevent my green bean casserole from becoming too watery?

To prevent excess moisture, make sure to thoroughly drain the blanched green beans. Also, avoid over-thinning the mushroom sauce when making it. 

Can I make this casserole ahead of time?

To prepare this dish ahead of time you can prepare the mushroom sauce in advance and refrigerate it. When you’re ready to assemble to casserole, reheat the sauce and proceed with the rest of the recipe.

Can I use different types of mushrooms in the mushroom sauce?

Yes! You can experiment with various mushroom varieties, such as cremini, shitake, or oyster mushrooms, to add depth and complexity to the sauce.

Ingredients
  

  • 1 tablespoon olive oil
  • 1 pound mushrooms sliced or diced
  • 1 sweet onion thinly sliced
  • 3 garlic cloves minced
  • 2 cups 2% milk
  • 3 tablespoons cornstarch
  • 2 tablespoons water
  • ½ teaspoon salt plus more to taste
  • ½ teaspoon black pepper
  • 1 teaspoon soy sauce
  • 2 pounds green beans fresh, trimmed, cleaned and cut in half
  • Cooking spray
  • 1 ½ cups panko bread crumbs

Instructions

  • In a large skillet over medium high heat, add olive oil and mushrooms and cook until mushrooms begin to soften and release their liquid, 10 minutes. Reduce the heat to medium, add the onion and garlic and cook until the onions are translucent, 5 more minutes.
  • Add the milk to the mushrooms and bring to a low simmer. Mix the cornstarch and water in a small bowl until well combined and add on top of the mushrooms, stirring frequently until the mixture thickens. Add salt, pepper and soy sauce.
  • Preheat the oven to 400°F and spray a 9×13 baking dish with cooking spray.
  • Bring a large pot of salted water to a boil. Prepare an ice water bath. Place the green beans in the pot and cook until crisp tender, 3 minutes. Strain the beans, shock in the ice water bath to cool. Strain the green beans again from the ice water bath and transfer to the prepared baking dish.
  • Add the mushroom mixture on top of the green beans and stir to combine. Sprinkle panko breadcrumbs on top and bake until browned and bubbling in the center, 10-15 minutes.

Notes

Storage: Store any leftovers in an airtight container in the fridge for up to 4 days.
Make Ahead Directions: You can make the soup up to 4 days ahead of time and keep it covered in the fridge. Don’t add it to the green beans until you are ready to bake the casserole so that they stay firm.
Substitutions: For best results, follow the recipe as is. However, here are some common substitutes that would work well in this recipe.
  • Make it gluten-free by using gluten-free panko breadcrumbs for the topping and use tamari sauce instead of soy sauce.

Comments

  1. I made this for Friendsgiving and Thanksgiving. I agree with another commenter that something is missing. I made it gluten/corn/soy free by using arrowroot starch and coconut aminos. I think it was missing seasoning so I added more pink Himalayan salt and extra coconut aminos. Tastes better, but I wonder if this would be better with half milk and half broth? The smoother soup idea is GENIUS. I’ve been making homemade green bean casserole for years. I love mushroom flavor, but hate texture so I always pick them out on my plate. Can’t believe I never thought to blend it.

  2. Made this today and used whole milk instead of 2%. It was not as flavorful as I would have liked. It is missing some thing but I am not sure what. I think I will try to make it again and add Parmesan cheese.

    1. Thank you for your feedback! Cheese definitely sounds like it could be a good addition – let me know if you try that!

  3. Ok this looks amazing, but my family hates mushrooms. I understand it’s a huge part of the dish. Anything I can substitute?

  4. I had never made green bean casserole before, and neither had my family. I made this for them and it was such a big hit. We all loved it! I was glad it was easy to make!!

  5. I have made the campbells soup green bean casserole. My son who is in his 20s hated it. I printed your recipe to make. I decided I was just going to skip it and make a quicker recipe. He saw your recipe and wanted to make it. It was delicious and we ate all the left overs. Everyone loved this green bean casserole Love your recipes ❤️❤️

  6. My Panco breadcrumbs were crispy white but they did not turn golden on baking even after 20 minutes at 175 Degree celsius. What could be the problem?

    1. I would cook it at a higher temperature 205C for 15 minutes. Or if you cook it at 175C, I would just cook it for longer!

  7. This was delicious! I had some leftover cooked greenbeans and went ahead and prep the moshrooms. This couldn’t have been easier!!! I added some parmessan cheesse at the end and was delicious and effortless. I did not pair it with anything else, but some potatoes would have been amazing!
