Ingredients
- 4 cups cut green beans
Cream of Mushroom
- 8 oz sliced mushrooms
- 4 cloves garlic
- 1 tablespoon unsalted butter
- 1/2 cup chicken stock or broth
- 1 cup heavy cream (or coconut cream)
- 2 ounce full fat cream cheese
- salt and pepper to taste
- 1/8 teaspoon xanthan gum (sub for 1/2 cup shredded mozzarella)
Onion Topping
- 1/2 sliced onion
- 1/2 cup almond flour
- 2 tablespoon unsalted butter
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
Instructions
Prep
- Use fresh string beans only. Fresh in the bag is fine but not frozen or canned. Slice them in half so they aren't too long.
- Steam string beans for 3-5 minutes until they haven't softened a little with a slight crunch. Set aside.
- Slice mushrooms. Slice 1/2 onion thinly for topping then set aside.
Cream of Mushroom
- In a hot pan on medium heat add chooped garlic gloves. Once fragrant add in mushrooms and cook mushrooms until withered. Once withered pour in heavy cream and add cream cheese.
- Do not let it come to full boil, allow it to steam but if it starts to simmer lower the heat a little. Add in 1/2 cup of chicken stock.
- Now, for thickness quickly whisk in 1/8 teaspoon of xanthan gum. If you don't want to use xanthan gum use 1/4 cup of chicken stock with 1/2 cup shredded mozzarella cheese.
- I tossed the sauce in a blender to chop up the mushrooms but that is optional. It helps with flavor and evens out the sauce.
Make The Casserole
- Preheat oven to 400°F
- Add steamed string beans into casserole dish then top with cream of mushroom sauce you made.
- In a seperate bowl mix salt and pepper into almond flour. Then toss almond flour and onions together. Most of the flour won't stick until the next step.
- Melt 2 TB of butter and pour over mixed almond flour and onions. Mix enough to where everything is coated and somewhat sticking together.
- Spread this across the casserole then place in preheated over for 40-50 minutes or until top turns golden brown. Allow to cool then serve.
Notes
Helpful Recipe Tips
- Adding cheese or xanthan gum for thickness is a great option. Having the inability to make a roux it will take forever to cook the water out of the cream. To speed up the process adding in cheese or xanthan gum is your best friend.
