Keto Green Bean Casserole

Step by Step Instructions

1. 1

   Preheat oven to 425°F. Toss onions, baking powder (or cornstarch), pork panko and salt together in a large mixing bowl. Spread on a parchment lined baking sheet. Spray with cooking spray.

   For this step

   • 1/2 medium onion, thinly sliced
   • 1 teaspoon baking powder or 1 tablespoon cornstarch
   • 1/4 cup pork panko
   • 1/2 teaspoon salt
2. 2

   Bake the onion rings at 425°F for 18-25 minutes, tossing every 6-7 minutes, until crispy and golden brown.

3. 3

   Fill a large saucepan with enough water to cover the green beans (but don’t add them yet). Add a few sprinkles of salt. Bring to a boil. Once boiling, add green beans and let them boil for 1-3 minutes. Taste one to check if it’s cooked through. Drain and immediately transfer the beans to an ice bath. Once cooled, drain again and set aside.

   For this step

   • 1 lb green beans, trimmed and halved
4. 4

   Melt butter in a large skillet over medium heat. Add mushrooms, 1/2 teaspoon salt, and pepper. Cook 5 minutes until the mushrooms start releasing their liquid. Stir in minced garlic and nutmeg. Cook 1-2 more minutes until fragrant.

   For this step

   • 2 tablespoons butter (unsalted)
   • 10 oz mushrooms, quartered
   • 1/2 teaspoon salt
   • 1/4 teaspoon pepper
   • 2 cloves garlic, minced
   • 1/4 teaspoon ground nutmeg
5. 5

   Sprinkle arrowroot powder over the mushrooms and stir to coat. Pour in the broth while stirring and simmer for 1 minute. Add heavy cream and cook for 6-8 minutes, stirring occasionally, until the sauce thickens.

   For this step

   • 1 1/2 teaspoons arrowroot powder
   • 1 cup chicken or vegetable broth
   • 3/4 cup heavy cream
6. 6

   Add blanched green beans to the cream of mushroom soup and stir to combine. Stir in remaining 1/2 teaspoon salt.

7. 7

   Transfer the green bean mushroom mixture to a baking dish or casserole dish. Top with fried onions. Bake at 400°F for 15 minutes or until hot and bubbly.
