Pork Rinds

When you make this be sure to use really healthy low carb and keto-friendly pork rinds such as these Pork King Low Carb Pork Breadcrumbs for the crispy onions. Many pork rinds you find in supermarkets contain unhealthy additives which won’t do at all.

Cooking Spray 

Also be sure to get a healthy cooking spray like this Primal Kitchen avocado oil spray. Most conventional cooking sprays contain questionable additives.

Soy lecithin is often added as an emulsifier. It’s a by product of processed soybean oil and is likely to contain pesticides and solvents. Not very appetizing is it?

Thanksgiving Keto “Sweet Potato” Casserole

Keto Green Bean Casserole


Crispy Onions:

• 1 tsp. Himalayan salt
• 2 tbsp. coconut flour
• 2 thinly sliced onions
• 3 tbsp. keto friendly ground pork rinds
• Healthy avocado cooking spray

Green Bean Casserole:

• 1 ½ cup organic chicken broth or turkey stock
• 1 lb. trimmed and cut green beans
• 1 tsp. arrowroot powder
• ½ cup organic heavy cream
• ½ tsp. freshly ground black pepper
• ¼ tsp. nutmeg
• 12 ounces sliced mushrooms
• 2 cloves minced garlic
• 4 tbsp. unsalted grass-fed butter
• Himalayan or Real salt – 2 tbsp. and 1 tsp.


1. Preheat oven to 425 F (200 C approx)

2. In a bowl, combine all the ingredients for the crispy onions.

3. Toss to make sure that the onions are coated evenly.

4. Spread the onions on a baking tray that’s lined with unbleached parchment paper. Spray with a healthy avocado oil.

5. Bake in the oven for 12 – 15 min. Observe carefully so as to keep them from burning. Then set aside to cool.

6. While the onions are being baked, you can start preparing the Keto Green Bean Casserole. Boil a gallon of water with 2 tbsp. of Himalayan salt. Add the green beans and blanch for 5 min. Drain and plunge them immediately into a bowl of iced water to prevent overcooking and to keep them nice and green. Set aside.

8. Melt the butter in a skillet. Add mushrooms and the remaining salt. Cook until such time that the mushrooms will release some of their liquid – about 5 minutes.

9. Add the garlic, pepper, and nutmeg. Mix well and cook for one minute more. Sprinkle in the arrowroot powder and stir well. Add the broth and let it simmer.

10. Lower the heat and whisk them in heavy cream. Cook until such time that the ingredients would thicken.

11. Remove from heat and add the green beans. Then place a handful of the cooked onions.

12. Place them in the casserole dish and top with the rest of the onions. Bake the Keto Green Bean Casserole for 15 more.
