Preparation of keto chicken and green bean casserole

A. Preparing the green beans:

  1. Blanching the green beans keeps their vibrant color, crisp texture, and nutritional value. To blanch, bring a pot of water to a rolling boil, then add the trimmed and cut green beans. Cook them for 2 to 3 minutes or until tender but still crisp. Immediately drain the green beans and plunge them into an ice water bath to halt the cooking process. Once they have cooled, drain them again and set aside.
  2. Steaming green beans are another way to preserve their nutrients and natural flavors. To steam, place the trimmed and cut green beans in a steamer basket over a pot of boiling water. Cover and steam for 5 to 6 minutes or until tender yet still crisp. Remove the green beans from the steamer and set aside.

B. Preparing the chicken:

  1. Cooking options: This casserole has several ways to cook the chicken. It depends on your preferences and the time you have available. You can:
  2. Boil – Place the chicken breasts or thighs in a pot of water or chicken broth. Bring the liquid to a boil, then reduce the heat to a simmer. Then cook for 15 to 20 minutes or until the chicken is ready. Remove the chicken from the pot and let it cool before shredding.
  3. Bake – Preheat your oven to 375°F (190°C). Season the chicken with salt and pepper, then place them on a baking sheet lined with parchment paper. Bake for 25 to 30 minutes or until the chicken is ready and reaches an internal temperature of 165°F (74°C). Let the chicken cool before shredding.
  4. Use rotisserie chicken – You can use rotisserie chicken as a time-saving option. Remove the skin and shred the meat, discarding any bones.
  5. Shredding the chicken into bite-sized pieces with two forks after it cools. Or, you can use your fingers or a pair of kitchen shears to shred the chicken. Set the shredded chicken aside, ready to assemble the casserole.

Making The Creamy Sauce

A. Sautéing the onion and garlic – Melt the butter over medium heat in a large skillet or saucepan. Once the butter has melted, add the chopped onion and cook for 3 to 4 minutes. Or until it becomes soft and translucent. Stir in the minced garlic and cook for 1 to 2 minutes or until fragrant. Be careful not to burn the garlic, as this can result in a bitter taste.

B. Pouring heavy cream into the onion and garlic mix while stirring creates the creamy sauce base. Stir in the chicken broth. Let the flavors blend, and the sauce thicken by simmering.

C. Adding and melting the cream cheese – Cut the cream cheese into small cubes and add them to the simmering sauce. Stir until the cream cheese melts and is well mixed into the sauce. The cream cheese will add creaminess and acidity to complement the sauce’s richness.

D. Seasoning the sauce – Now it’s time to perfect the sauce. Stir in the Dijon mustard, which adds a mild tang and a hint of spice. It will enhance the flavor profile of the sauce. Taste the sauce and adjust the salt and pepper according to your preferences. Remember that the flavors will intensify as the casserole bakes, so it’s best to season at this stage. After seasoning the sauce, remove it from the heat and set aside, ready to assemble the casserole.

Assembling the casserole:

A. Layering the ingredients – Preheat your oven to 375°F (190°C) to assemble the casserole. Combine the shredded chicken and cooked green beans in a large mixing bowl. Toss to distribute the ingredients. Pour the creamy sauce over the chicken and green beans, using a spatula to spread it across the mixture. Make sure the creamy sauce covers the casserole.

B. Before baking, add crunch with almond flour or pig rinds. A crispy, golden-brown crust will enhance the creamy sauce. Sprinkle-grated parmesan cheese over the casserole.

C. Bake the casserole for 20 to 25 minutes until the top is golden brown, and the casserole is hot. The crunchy topping from almond flour or crushed pork rinds complements this dish. Keep an eye on the casserole while it bakes, and cover it with foil if it starts to brown.

D. Garnishing and serving – Remove the casserole from the oven and allow it cool before serving. Chopped fresh parsley provides color and a fresh, herbaceous flavor creamy sauce. Enjoy this ketogenic comfort dish hot from the oven!
