Ingredients
- 2.5 cups cut green beans (can range anywhere from 2-3 cups is ideal)
- 1/2 white onion
- 8 oz sliced mushrooms
- 1/4 cup white wine vinegar
- 1/2 cup chicken bone broth (regular chicken broth is fine)
- 1 cup heavy cream (or coconut cream)
- 1 tablespoon unsalted butter
- 1 teaspoon salt
- 1 teaspoon coarse black pepper
- 2 tablespoon olive oil
optional for cream thickness. One or the other
- 1/8 teaspoon xanthan gum
- 1/4 cup shredded cheese
Instructions
- If using canned string beans proceed to step 4. Wash and cut string beans up to desired size
- Boil string beans to soften. About 5-10 minutes. Don't overcook because they will cook in the oven as well.
- After finish boiling drain them then make cream sauce for casserole.
- Sliced onion and mushrooms. On medium heat sweat the mushrooms to remove excess water.
- After they are done add in olive oil and toss in sliced onions then season with salt and pepper.
- Cook mushrooms and onions down then add in butter and allow to melt then incorporate.
- Pour in white wine vinegar and allow the vinegar to completley reduce making sure you don't burn anything watch the heat. If onions/mushrooms look dry add a little oil but they shouldn't.
- After vinegar has reduced add broth to the pan. Bring to boil then lower to simmer and reduce by half.
- Pour in heavy cream and reduce to simmer as well. Allow to thicken. If you want a thicker sauce since there is no roux add in 1/8 tsp xanthan gum or 1/4 cup of cheese of choice.
- Preheat oven to 300ºF then layer string beans in casserole dish.
- Mix in cream sauce and string beans then bake for 20 minutes. Allow to cool then serve.

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.
- Using canned string beans to make the recipe even faster to make!
- Skipping the parmesan chips. They are only optional for a crunchy topping but they don't add the same element the onion straws do. Although you can purchase onion flavored chips to help.
