How To Make A Keto Green Bean Casserole- Step by Step
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Pour string beans in casserole dish then add made from scratch cream sauce and mix.
- Place in oven at 300F for 20 minutes. Then top with crumbled parmesan chips.

- 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.
- Sub out chicken bone broth for chicken broth. But you will lose the health benefits of the nutrient packed broth.
