  • 2 pounds green beans (fresh, trimmed)
  • 5 slices bacon (fresh, trimmed)
  • 2 cups cremini mushrooms (fresh, trimmed)
  • 2 cups onions (fresh, trimmed)
  • 1/4 teaspoon salt
  • 3 tablespoons avocado oil (fresh, trimmed)
  • 2 cups cauliflower (fresh, trimmed)
  • 1 cup coconut milk
  • 4 cloves garlic
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon nutmeg
  • 1 tablespoon nutritional yeast
  • 3 egg yolks


  • Pre-heat your oven to 400F.Combine the cauliflower, garlic cloves and coconut milk in a sauce pot, cover with a lid and heat over medium heat.
  • Cook here until the cauliflower is fork tender.In the meantime, arrange your green beans side by side vertically in rows, in one flat layer over 2 sheet pans.
  • Sprinkle the mushrooms all over.
  • Cut the bacon into small pieces and distribute it evenly over all of the veggies.
  • Sprinkle with a pinch of salt.
  • Roast for 20 minutes, middle and bottom rack.
  • Rotate the pans after 10 minutes.In the meantime heat a large skillet over medium heat.
  • Add in the oil or butter then the onions.
  • Sprinkle in the salt.
  • Use tongs or forks to gently toss.
  • Then cover with a tight fitting lid.
  • Stir every 5 minutes until green beans are ready.
  • They will begin to get tender, then translucent, then browned and finally soft and sweet with some toasty bits!By now the cauliflower should be soft.
  • Carefully transfer all the contents of the sauce pot to a blender.
  • Blend on high until smooth, add in a little bit of water or broth if needed.
  • Then add in the egg yolk one at a time until fully combinedWhen the green beans are ready remove them from the oven.
  • They will be browned and crunchy, try not to eat them all.Arrange them in a casserole dish, I like to arrange them in little bunches with the greens beans (with the mushrooms and bacon pieces) all facing the same way, makes it easier to serve.
  • Pick a few pieces of bacon out and set them aside.Pour the cream sauce all over the green beans and use a spatula to spread it out.
  • Then top with the caramelized onions and those bacon pieces you set aside.Pop the casserole in the oven and bake for 20 minutes.Remove from the oven, and serve!
