Print Recipe
Pin RecipeIngredients
- 1 pound fresh green beans, cleaned, trimmed and halved
- ½ cup blanched almond flour (I use this brand)
- 1 teaspoon sea salt
- ½ teaspoon black pepper
- 1 small onion, thinly sliced
- 2 large shallots, thinly sliced
- 8 ounces cremini mushrooms, rough chopped
- 2 tablespoons butter
- 3 cloves garlic, minced
- ½ cup chicken stock
- ½ cup heavy cream
- ¼ cup grated Parmesan cheese
- avocado oil (or frying oil of your choice)
Instructions
- In a large pot of salted water, bring the green beans to a boil. Boil for 5 minutes. Drain in colander and submerge the beans in an ice water bath to shock them and stop the cooking process. Drain and set aside.
- In a large mixing bowl, combine almond flour, sea salt, and black pepper. Add onions and shallots and toss until they are well coated.
- In a large skillet over medium-high heat, heat ½ inch of avocado oil. Once the oil is hot, add breaded onions and shallots in small batches and fry until crispy and golden brown.
- Remove them from the oil and spread out on a paper towel to remove excess grease.
- Drain skillet and reduce heat to medium. Add the mushrooms, butter and garlic to the pan.
- Sauté the mushrooms and garlic for 5 minutes.
- Preheat oven to 400°
- To the skillet, add heavy cream, and chicken stock. Bring to a boil over medium heat and then reduce heat to low and let simmer to thicken. Once sauce has started to thicken, stir in Parmesan cheese.
- Add green beans to sauce and stir until they are coated. Transfer mixture to a casserole dish. Spread crispy onions and shallots out evenly around the perimeter of this dish. Bake 15 minutes.

I have yet to find a heavy cream with some unhealthy chemicals included. Though I live in a rural area and we do not have access to much in the way of organic foods here, I still won’t purchase these items. I am guessing that I can substitute organic coconut milk for the heavy cream?
Thanks for your response! I use many of your recipes and we haven’t been disappointed yet! Thank you for all you do!
Sincerely, Sharon

Kyndra is the expert……but just wanted to quickly state, That No, I am sure, she would agree, Coconut Milk is Wrong….It’s Sweet for Desserts. Better off using can cream/ regular milk if you’re in rural area.

Half an inch of avocado oil? Here in UK, avocado oil is the most expensive oil you can buy. Why can’t you use an alternative?

Plan on making this for Thanksgiving this year. Do you think this could be made and assembled the day before? I hate leaving everything to the last minute. It takes the joy out of meal preparation. Thanks!

Yes, I definitely think you could. I would probably do the onions and shallots right before serving though.
