Whole30 Chicken Broccoli Casserole

This Whole30 Chicken Broccoli Casserole combines shredded cooked chicken, broccoli florets, mushrooms, and onions under a creamy Vegan Alfredo Sauce. It is baked until bubbly and slightly thickened, delivering a hearty and savory casserole featuring tender vegetables and protein. The dish offers a flavorful, silky sauce coating the ingredients, suitable for a filling main course that can be prepared ahead with the sauce made in advance.

Description

The Whole30 Chicken Broccoli Casserole features cooked shredded chicken layered with sautéed cremini mushrooms, diced onion, and crisp-tender broccoli inside a casserole dish. The topping uses a Vegan Alfredo Sauce mixed with chicken broth to create a creamy layer that envelops the vegetables and chicken during baking. This dish is baked at 400°F until the sauce thickens and bubbles, providing a warm, savory casserole with a balance of textures from tender meat and vegetables and a smooth, rich sauce.

The sautéing of mushrooms, onions, and broccoli briefly before baking helps develop flavor while maintaining the broccoli’s bright color and slight crunch. The casserole's creamy sauce and meat make it a filling meal appropriate for lunch or dinner. Its components and preparation method allow it to be a practical meal prep option, with the sauce able to be made the day prior and the casserole baked at serving time.

This casserole can be garnished with rosemary for additional fragrance and visual appeal. It pairs well as a standalone meal or alongside a simple salad for a balanced plate.

Preparing the Vegan Alfredo Sauce requires soaking cashews ahead of time, so planning is necessary. The recipe suits those following Whole30 principles and is adaptable for meal prepping by making the sauce in advance and combining the cooked ingredients later for baking.

Ingredients

Servings
  • 4 cups chicken cooked and shredded
  • 2 tbsp olive oil
  • 2 broccoli florets removed, heads
  • 10 cremini mushrooms sliced
  • 1/2 onion diced, small
  • 1 cup chicken broth
  • 1 recipe Vegan Alfredo Sauce
  • salt to taste
  • black pepper to taste
  • rosemary for garnish

Instructions

  1. Make the Vegan Alfredo Sauce and set aside. This can also be made the day before and stored in the fridge.
  2. Preheat the oven to 400 degrees fahrenheit.
  3. Heat the olive oil in a large sauté pan over medium heat. Add the sliced mushrooms and diced onion and stir for 3 minutes. Add the broccoli florets (make sure they're in bite-sized pieces and not too large) and stir for another 3 minutes or until the broccoli is crisp-tender and bright green.
  4. Place the shredded chicken in a 9x13-inch casserole dish, covering the bottom. Add the sautéed mushrooms, onions and broccoli in a flat layer on top.
  5. Stir the chicken broth into the Vegan Alfredo sauce, then pour on top of the broccoli in the casserole dish. Use a spatula if needed to make sure everything is well coated.
  6. Cook the casserole for 20-25 minutes. The sauce should be bubbling and slightly reduced and thickened. Garnish with fresh rosemary if desired and serve immediately.

Notes

  • Prepare the Vegan Alfredo Sauce in advance by soaking cashews, as this step is necessary before blending the sauce.
  • This casserole is convenient for meal prep; making the sauce a day ahead and assembling the casserole before baking saves time.
