Ingredients

  • For the green beans:
    • 1 1/2 lbs (680 g) fresh green beans, trimmed and chopped
  • For the mushroom sauce:
    • 2 tbsp clarified butter or ghee
    • 2 cups button mushrooms, sliced
    • 1 large yellow onion, diced
    • 2 cloves garlic, minced
    • 1 tbsp coconut aminos
    • 1/2 cup coconut cream (thick part only)
    • 1 cup vegetable or chicken broth
    • 1 tbsp gluten-free flour or arrowroot powder
    • 1/4 tsp sea salt (more to taste)
    • 1/4 tsp black pepper (more to taste)
  • For the crispy onions:
    • 1 large yellow onion, sliced into thin rings
    • 2 large eggs
    • 4 tbsp gluten-free flour
    • 2 tbsp avocado or olive oil
    • Pinch of salt and pepper
  • Optional garnish:
    • Chopped parsley
    • Sea salt flakes
    • Freshly ground black pepper

Instructions

  1. Preheat oven: Preheat to 375°F (190°C). Lightly grease a 9×13-inch (23×33 cm) casserole dish.
  2. Make crispy onions: In a bowl, whisk eggs and gluten-free flour until smooth. Season with salt and pepper. Heat 1 tbsp oil in a skillet over medium-low heat. Dip onion rings in batter and fry in batches 2–3 min per side. Drain on paper towels. Repeat with remaining oil and onions.
  3. Blanch green beans: Boil green beans for 3–4 min until bright green. Transfer to ice water bath for 1–2 min, then drain well.
  4. Make mushroom sauce: In a skillet, melt ghee over medium heat. Sauté mushrooms, onion, and garlic for 4–5 min. In a bowl, whisk coconut cream, broth, coconut aminos, and flour until smooth. Add to skillet and stir 3–5 min until thickened. Season to taste.
  5. Assemble casserole: Spread green beans in prepared dish. Pour sauce over and toss gently to coat. Top with crispy onions.
  6. Bake: Cover loosely with foil or parchment. Bake 20 min until bubbly and lightly golden. Let rest 5–10 min before serving.
  7. Garnish: Top with parsley, sea salt flakes, and fresh pepper if desired.

Notes

  • Use frozen green beans if needed—thaw and pat dry first.
  • Crispy onions can be made a few hours in advance but are best added just before baking.
  • Adjust salt depending on broth and coconut aminos used.
