Preheat the oven to 350F.

Drizzle some olive oil into the base of a baking dish. Add the chicken breasts and drizzle with a little more oil. Season with salt and pepper.

Cover the dish in foil and roast until the chicken has reached 165F.

Meanwhile, make the sauce by combining cream cheese, chicken broth, diced jalapeño, onion powder, and minced garlic to a saucepan. Once the cream cheese has melted, add some unsweetened almond milk and shredded cheddar cheese. Season with black pepper.

Once the chicken has cooked, drain any excess liquid from the dish, then cover the chicken with the sauce. Roast for an additional five minutes, uncovered.
