Benefits Of Made From Scratch Keto Green Bean Casserole

  • Adding in what you like to eat.
  • Knowing all the ingredients being used.
  • Making something homemade that people think is hard.
  • Staying in the limits of the keto diet.

How To Make A Keto Green Bean Casserole- Step by Step

  1. Cut up about 2 pounds of string beans. Cutting them into small bite sizes. Then boil the green beans for about 10 minutes. Just softening them a little. Do not overcook them because they will go in the oven.
  2. Slice up 1/2 onion and mushrooms. Some mushrooms come pre-sliced and that’s fine. Afterward add mushrooms to a pan on medium heat to allow the mushrooms to sweat and release excess water.
  3. After mushrooms have shrunken up a bit add oil and raw onion into the pan. Cook these down adding salt and pepper in the meantime.
  4. Toss in 1 TB of butter and add in white wine vinegar for flavor. Cook this down almost completely. Meaning keep a close eye on the heat to avoid burning or allowing them to get dry. If they look a little dry toss in some oil.
  5. When vinegar has cooked down pour in chicken bone broth or regular broth. Bring to boil then lower heat to simmer and reduce by half.
  6. After broth has reduced add in heavy cream. Bring to a boil then simmer as well until sauce thickens. A tip to speed the process for a thicker sauce are cheese or 1/8 teaspoon of xanthan gum. If you use neither sauce won’t get but so thick.
  7. Pour string beans in casserole dish then add made from scratch cream sauce and mix.
  8. Place in oven at 300F for 20 minutes. Then top with crumbled parmesan chips.

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.

    This recipe is sooo good! You can use canned fried onions instead. They have a bit more crunch and cut down on the time. I’m wondering if you could make this, freeze it and cook it later?

    This is amazing! The mushroom flavor and consistency feel and taste like what mushroom soup should. The combination is decadent and delicious!! I also used gluten free fried onions to save a bit of time and even used canned green beans ( lots to cook on Thanksgiving!) and I used an immersion blender but left some of the mushrooms a little bigger. Everyone wanted the recipe!
