Green Bean Filling:

2 2/3 Cups (400g) Fresh OR Frozen Green Beans

2 Cups (250g) Button Mushrooms

1/3 Cup (80mL) Chicken Broth

8oz (224g) Full Fat Cream Cheese

1/2 Cup (56g) Cheddar Cheese

1 Clove (3-4g) Fresh Garlic

1 Tbsp (14g) Butter

1/3 Tsp Dried Thyme

Salt & Pepper

Pork rinds (for topping)

Crispy Onions:

1/2 (40g) A Small Onion

2 Tbsp (14g) Blanched Almond Flour

1/2 Cup (120g) Avocado Oil, For Frying


  1. Preheat your oven to 350℉ (177℃).
  2. If using fresh green beans, boil them in salted water for about 10 min or until tender. If using frozen green beans, defrost them. Drain the green beans and set aside. Shred the cheddar and set aside.
  3. In a large non-stick pan over medium heat, melt the butter. Sauté the mushrooms and garlic for a few minutes. Season with salt, pepper, and thyme.
  4. Stir in the chicken broth and deglaze the pan. Then add the cream cheese, stirring occasionally until it melts.
  5. Turn off the heat. Add the green beans to the pan and stir gently. Transfer everything to a small casserole dish. Top with the cheddar and bake for about 10 minutes or until hot throughout.


  1. Coat the sliced onions with non-stick baking spray, add them to a small bowl, and coat them in the almond flour.
  2. Then, in a medium non-stick pan, heat the oil. Add in the onions and fry until golden brown.
  3. Let them cool on a paper towel-lined plate.
  4. When the casserole is ready, top it with the onions and crushed pork rinds.
