Step 1

Heat oven to 425°F.

Step 2

Toss cauliflower with olive oil and season with salt & pepper. Arrange in a deep 9 x 13 inch baking dish and roast (uncovered) for 25-30 minutes, until softened.

Step 3

While cauliflower is cooking, start working on the sauce: Melt butter over medium heat. Add the ranch seasoning and flour, and stir until it is all combined and crumbly.

Step 4

Gradually (working in 1/4 cup increments), add in the almond milk, stirring continuously to make a creamy sauce. This may take 10-15 minutes, so be patient.

Step 5

When all the almond milk as been added and sauce is thickened, add 1 1/2 cups of the shredded cheese in 3 batches. Stir until completely melted and remove the sauce from the heat.

Step 6

Stir in 1/8 to 1/4 teaspoon of salt. Have a quick taste and decide how you'd like it.

Step 7

When cauliflower is slightly soft, stir in the chicken breast pieces and pour the sauce over everything.

Step 8

Return to the oven for 10 more minutes (uncovered).

Step 9

Sprinkle with the remaining cup of cheese and return to the oven for 5-10 more minutes (uncovered). Cut into a piece of chicken to see if it's ready.

Step 10

Allow casserole to rest for 10 minutes (this helps the sauce thicken up).

Step 11

Casserole may be cooked ahead and portioned out into meal prep containers. Heat until steaming hot in the microwave.
