Preheat your oven to 200 degrees and line two baking sheets with paper towel.
Using the 3mm blade (or blade c), spiralize your zucchinis. Divide the zucchini noodles between the two paper towel-lined baking sheets in a flat layer. Sprinkle evenly with salt. (don't worry the paper towel won't burn at such a low temp!)
Bake the zucchini noodles in the oven for 40 minutes to dry them out. Once cooked, cover with paper towel and press out any excess moisture. Repeat once more with an additional paper towel. Set aside.
Bring your oven up to 375 degrees and place the Greek yogurt, BBQ sauce and 1 cup of cheese in a large saucepan over medium-low heat. Cook until the cheese just begins to break down and look melty and “stringy,” about 8-10 minutes, whisking regularly. *
While the cheese melts, toss together the shredded chicken breast, cilantro and dried zucchini noodles into a large bowl. Lightly cut up the mixture up with a fork and knife to make it easier to evenly mix, as well as cut, once cooked.
Once the cheese has begun to melt, pour the sauce over the zucchini noodle mixture and season with a pinch of pepper. Mix well until the sauce evenly coats all the noodles.
Spread the casserole into a casserole dish and bake for 20 minutes. Sprinkle with the remaining cheese and bake until golden brown and bubble, about 20-25 more minutes.
Once cooked, let the casserole cool for 20 minutes (don’t skip this!) to let it set and absorb some of the water.**
Cut and drizzle with extra BBQ sauce and cilantro, if desired. DEVOUR.
