Preheat your oven to 375°F.
In a greased 9x13-inch baking dish or oven-safe skillet, add orzo, blended cottage cheese, spinach (or chopped zucchini), pesto, broth, parmesan, cherry tomatoes, garlic, and a pinch of salt and pepper. Stir until well combined.
Nestle the raw chicken thighs into the orzo mixture. Drizzle lightly with olive oil and season the tops with salt and pepper.
Cover tightly with foil and bake for 20 minutes.
Remove foil and bake uncovered for another 10–15 minutes, until the orzo is tender, the sauce is creamy, and the chicken is fully cooked.
Let cool slightly before serving. Optional: top with extra parmesan or a spoonful of pesto.
