This green bean casserole is a homemade version of the classic comfort food. It doesn’t use canned soup, but it’s still very easy to make. It’s creamy, has a lot of flavor from the caramelized onions and mushrooms, and has French’s Onions on top for the perfect crunch.
Ingredients
- 2 tablespoons of olive oil
- 1 medium onion, thinly sliced
- Kosher salt and freshly ground black pepper to taste
- 1 pound of mushrooms (cremini, button, oyster, or maitake), cut into 4 parts
- 1 pound of green beans, with the stems trimmed and cut in half or roughly chopped
- 2 tablespoons of unsalted butter
- 2 tablespoons of flour
- 1¾ cups of whole milk
- 1 clove of garlic, finely chopped or grated
- 2 tablespoons of soy sauce or tamari
- French’s Crispy Fried Onions, as much as you want for topping
How to Get Ready Step by Step
Step 1: Cook the onions.
- Put the olive oil in a large skillet (7 inches or more) over medium-high heat to warm it up.
- Add the chopped onions and some salt and pepper. While the onions cook for 10 to 12 minutes, or until they are soft and starting to turn golden brown, stir them every so often.
Don’t rush this step because it adds flavor.
Step 2: Put in the mushrooms
- Put the pan on medium-low heat and then add the mushrooms. Taste and add more salt and pepper if needed.
- Every so often, stir the food and cook it for another 10 to 12 minutes. The mushrooms will release moisture, then shrink and turn brown. At the end, the onions should be brown and well-caramelized. That’s what you need.
Step 3: Make the green beans cook.
- Put the green beans directly into the skillet. It might look full at first, but don’t worry.
- Mix everything together and then add salt and pepper to taste. While the green beans are cooking for 8 to 10 minutes, stir them every now and then until they are:
- Bright green
- completely soft
Step 4: Prepare the Creamy Sauce
- Put the butter in the skillet and let it melt.
- Spread the flour evenly over the vegetables and stir them constantly for 2 to 3 minutes. This gets rid of the taste of raw flour and makes the sauce thicker.
- Pour in the milk slowly while stirring. Let the mixture get thicker before you add more.
Now add: • Soy sauce (or tamari) • Garlic
- Mix well and let the mixture come to a gentle boil. The sauce should cover all of the vegetables evenly.
Adjust the spices to suit your taste.
Step 5: Put the casserole in the oven.
- Set your oven to 220°C (425°F).
- Add a lot of French’s Crispy Fried Onions to the green bean mix.
- Put the skillet in the oven (or move it to a baking dish if your skillet can’t go in the oven) and bake for 20 to 25 minutes, or until the top is golden brown and the edges are bubbly.
Tips for Making
- You can make the casserole without the onion topping up to a day ahead of time.
- Keep it in the fridge with the lid on.
- Add the fried onions when you’re ready to bake and follow the directions.
Leftover food
To be honest, this casserole is best when eaten again the same way:
- For the best texture, reheat in the oven.
- Or use the microwave for ease.
