Anyway, let's not waste any more time and get into the recipe!
Step 1: Prep Work For This Keto Casserole
Begin by preheating your oven to 350℉ (177℃).
Next, you'll get your green beans ready. If you're using fresh green beans, you'll need to boil them in salted water for about 10 min or until they're tender. If you're using frozen green beans, then you'll need to defrost them. To defrost them, you can put them in a microwave-safe bowl and add a small amount of water. Then cover with a paper towel and heat for about 1-2 minutes.
However, whether you choose fresh green beans or frozen green beans, you'll still need to drain them and put them aside in a bowl for later.
Add the shredded cheese to a small bowl and set it aside for later.
Step 2: Sautéing The Ingredients & More
Next, you'll want to melt the butter in a large non-stick pan over medium heat. When the butter is melted, toss in the sliced button mushrooms, and add the garlic. Sauté everything for a few minutes, making sure to season it with the thyme. You can also add salt and pepper to taste at this point as well.
After a few minutes of cooking, slowly stir in the chicken broth and deglaze the pan. Then, add the cream cheese and occasionally stir until it completely melts in the broth.
Next, turn off the heat and add the green beans you set aside previously. Be sure to stir the beans gently into the cream cheese mixture to get them evenly coated with it.
Step 3: Baking The Casserole
Transfer everything from the pan into a small casserole dish. Top the mixture with the cheddar cheese you shredded earlier. Bake for about 10 minutes or until hot throughout. You'll know it's ready when the cheese turns a nice, golden color.
Step 4: Making The Crispy Onions
While your casserole is baking, you'll want to get your keto crispy onions ready.
Start by coating the sliced onions with non-stick baking spray and then add them to a bowl. Then, you'll toss them in almond flour until all of them are evenly coated with it.
Now, in a medium non-stick pan, heat the avocado oil until it begins to steam. After this starts to happen, add in the onions and fry until they turn golden brown. Now, set them aside, and let them cool on a paper towel-lined plate until your casserole is done baking.
Step 5: Serving the casserole
When the casserole is ready, carefully take it out of the oven, and let it cool for just a minute or two. Top it with the crispy onions and spread them evenly on the surface of the casserole. Finally, add in some crushed pork rinds as a garnish, and your casserole is ready to serve!
Storage and Reheating Instructions
Ok, so you've made this keto green bean casserole, you loved it, and now you have leftovers that need to be stored.
In the refrigerator, your leftovers will last up to 5 days if you store them in an airtight container. However, if you don't think you will eat all of the green bean casserole in 5 days, you can always freeze it for up to 6 months.
No matter which option you choose, you can't go wrong. This keto casserole heats up incredibly well, and it might even be better the next day/s you make it. To reheat, just put it back in the oven at 350°F for about 10 minutes or until it's warm.
