Instructions

1. Preheat the oven to 375 degrees F. and add the broccoli into a 9×13 casserole dish
2. In a skillet over medium-high heat, add the diced onion, garlic and olive oil and sauté for 4-5 minutes until the onion is soft and translucent. Add the onions to the casserole dish with the broccoli
3. Add all of the sauce ingredients except for the egg into a container you can use for mixing with an immersion blender or into your blender. Blend for 3-4 minutes, or until the cashews are completely blended and the sauce is creamy and smooth
4. Add the egg into the sauce and blend for about 15 seconds, just until combined. Do not over mix it into the sauce
5. Pour the sauce into the casserole dish with the broccoli and onions and stir it in so the broccoli is completely coated and the sauce is evenly distributed in the casserole dish
6. Bake for 1 hour, uncovered, or until the top of the broccoli casserole doesn’t have any excess liquid sitting in the middle. You may need to cook an additional 15 minutes, which happens most often when using frozen broccoli instead of fresh broccoli. The casserole is done and fully cooked when the top is a cheesy golden brown color
7. Remove from the oven, garnish with any additional parsley and let sit for 5 minutes before serving
