How to Make Green Bean Casserole
First, you will prep the green beans and mushrooms to add to the baking dish. Before doing anything, preheat your oven to 375 degrees Fahrenheit.
- Mince shallots and garlic. Cut button mushrooms into slices. Prepare the green beans by washing, trimming, and cutting them into halves or thirds.
- Boil the green beans for 3 minutes, then place in ice water to blanch them.
- Once the beans cool, place them in a strainer to drain them, then add them to a 9 by 13-inch casserole dish.
- Heat a skillet over medium heat and melt butter. Saute the garlic and shallots for 2-3 minutes.
- Add the sliced mushrooms with salt and pepper and saute for 8 minutes. After sauteing, place them in the casserole dish with the green beans.
How to Make Cream of Mushroom Soup
- Cut button mushrooms into small chunks - smaller than the slices of mushrooms you cut earlier.
- Melt butter in a skillet over medium heat and add the mushrooms to it with salt and pepper. Saute 5-6 minutes, then remove to a bowl.
- Reduce the heat to medium-low and add more butter. Once melted, sprinkle in gluten-free flour and stir together to create a paste-like consistency known as a roux.
- Slowly add chicken broth to the skillet while stirring. Once incorporated, add evaporated milk, continuing to stir.
- Finally, season and continue stirring until creamy and thickened.
Finally, assemble your gluten-free green bean casserole and bake.
- Pour homemade cream of mushroom soup into the casserole dish over the green beans and mushrooms. Stir together to fully incorporate.
- Place the baking dish into the oven and bake, uncovered, for 25 minutes.
- After 25 minutes are up, remove and top with gluten-free French fried onions or gluten-free panko breadcrumbs. Spread over top and bake for another 10 minutes.
- Remove and allow to cool slightly before serving. Enjoy!
Green Bean Casseroles FAQs
Unwashed fresh green beans will keep well in the refrigerator for about 1 week. Keep them in the vegetable drawer of your refrigerator in an airtight container or sealed plastic bag.
To make green bean casserole ahead of time, simply prepare as directed without baking. Store in the refrigerator for up to 3 days, then bake when ready to serve.
You can make green bean casserole with frozen green beans by defrosting them first. Thaw frozen green beans by removing them from the package and placing them in a colander. Place the colander under running cool water, occasionally stirring as they thaw. In about 30 to 45 minutes, the beans should defrost. Alternatively, you can defrost them in the microwave; however, green beans tend to taste better when thawed under water.
You can make green bean casserole with canned green beans if you prefer. Follow the rest of the recipe step-by-step as instructed.
The only dairy in my gluten-free green bean casserole recipe is butter and evaporated milk. To make dairy-free green bean casserole, you will need to replace these two ingredients. Use a vegan butter substitute to replace the butter.
For the evaporated milk, you can easily make your own dairy-free alternative. Evaporated milk is milk that has been boiled down to reduce its water content. So, to make your own dairy-free evaporated milk, boil your milk alternative on the stove until it reduces by half.
For best results, use almond milk. Boil for 30 minutes on the stove until the contents of your pan reduce by half the amount you started with. For ½ cup evaporated milk, you'll want to boil down at least 1 cup of almond milk in a saucepan.
You may also be able to find a vegan evaporated milk substitute at the grocery store, such as evaporated coconut milk. If you are able to find it at the store, you can use that instead.
Alternatively, you can leave out the evaporated milk and use regular dairy-free milk instead. The texture will not be the same, but it should still thicken properly.
Fresh Green Bean Casserole Toppings
- Green bean casserole with cheese: Cheddar cheese or Parmesan cheese are great choices for making green bean casserole with cheese. Top with cheese before baking.
- Green bean casserole with bacon: Bacon is an incredible addition to green bean casserole. To make green bean casserole with bacon, I cook my bacon separately and then crumble it on top. Try combining cheese and bacon for a green bean casserole unlike any you've had before!
