Asparagus Casserole (Green Bean Casserole Imposter)

This is in honor of the age-old American Thanksgiving tradition of the Green Bean Casserole!  I have substituted the green bean pods with asparagus chunks…made a homemade condensed mushroom soup…and have baked the traditional fried onions on top…I think you’ll enjoy the result!

“Fried” Onions:
2 small onions, finely sliced
1/4 cup arrowroot
1/4 cup almond meal
2 tablespoons avocado oil, or preferred oil

“Condensed” Mushroom Soup:
1 cup chicken broth (homemade preferred)
8 ounces baby Bellas (or mushrooms of choice), sliced
1 celery stalk, chopped
1 tablespoon ghee or organic butter
1 small parsnip, peeled and chopped
1 teaspoon cooking Sherry
1 teaspoon sea salt
1 teaspoon ground pepper

2 bunches steamed asparagus, diced
1/4 cup organic whipping cream (optional) or coconut milk

Put sliced onions in a bowl. Add 1 tablespoon of avocado oil. Distribute oil over onions with your hands (or with a spoon if you desire).

Preheat oven to 350 degrees.

Place almond meal and arrowroot in a gallon plastic bag. Shake. Add oiled onions to mixture. Take remaining oil and brush onto a baking dish. Distribute onions.

Cook for 15 minutes. Stir. Cook for 10 minutes. Stir. Cook an additional 5 minutes. (Onions will be somewhat crispy, some moister…that’s OK because the rest will crisp later). Set aside.

In a saucepan, add mushrooms, celery, butter, parsnip, salt, pepper and chicken stock. Heat on medium-high until parsnips are tender. Add Sherry. Using an immersion blender, blend until smooth (or use a stand blender or food processor). Add optional whipping cream.

Mix the mushroom mixture with asparagus.

In an 8×8 greased pan, pour in mixture. Cook for 15 minutes. Add crispy onions on top. Cook for an additional 15 minutes. Let set for at least 20 minutes to thicken.
