Low-Carb Pesto Caprese Chicken Casserole

Low-Carb Pesto Caprese Chicken Casserole

Think keto and casseroles can’t go together? Think again! This low-carb friendly casserole has layers of tender chicken, cheesy mozzarella and parmesan, tangy pesto, spinach, and roasted cherry tomatoes! Doesn’t that sound amazing?

This is a super easy recipe that will please even the pickiest of eaters, even the ones who don’t normally eat keto. How could you go wrong with cheese and chicken? And when I say easy I mean really easy.

All you have to do is layer the chicken cutlets into a large casserole dish, top with pesto, spinach, and mozzarella then top with another layer in the same order. After that you’ll add the cherry tomatoes to the sides and sprinkle with some parmesan and bake until bubbly. For a complete meal I would serve this with a green salad and an Italian vinaigrette.
