Preheat your oven to 180°C (350°F) and give it enough time to fully heat up before you place anything inside—this helps the chicken cook evenly from the start. While the oven is heating, lightly grease your baking dish with a small amount of oil or butter, spreading it across the base and sides so nothing sticks and the rollups release easily after baking.

Take your chicken breasts and slice them horizontally into thinner, even fillets. If any pieces are still thick, place them between two sheets of parchment paper and gently pound them with a rolling pin or the back of a heavy utensil until they are uniform in thickness. This step is important because evenly sized pieces cook at the same rate and are much easier to roll without tearing.

In a mixing bowl, add the softened cream cheese, shredded cheese, ranch seasoning, garlic powder, salt, and pepper. Use a spoon or spatula to mix everything together thoroughly until the mixture becomes smooth, creamy, and well combined. Make sure there are no lumps of cream cheese left, as a smooth filling spreads more evenly and gives a better texture inside the rollups.

Lay each piece of chicken flat on your work surface and spread a generous but even layer of the creamy mixture over it. Use the back of a spoon or spatula to gently spread it all the way to the edges, but avoid adding too much filling, as overfilling can cause it to spill out while baking.

Starting from one end, carefully roll each chicken piece tightly into a log shape, keeping the filling inside as much as possible. Once rolled, secure each piece with one or two toothpicks to help it hold its shape during cooking. Try to keep the rolls snug but not overly tight, so they cook evenly.

Place each rollup seam-side down in your prepared baking dish, spacing them slightly apart so heat can circulate around them. Once all the rollups are arranged, drizzle a small amount of olive oil over the top of each one—this helps keep the chicken moist and encourages a light golden color as they bake.

Transfer the dish to the center rack of your preheated oven and bake for about 25–30 minutes. Check them toward the end of the cooking time—the chicken should be fully cooked through, and the tops should look lightly golden with some bubbling from the cheese filling. If needed, you can bake for an extra few minutes to achieve a slightly more golden finish.

Once done, remove the baking dish from the oven and let the rollups rest for about 5 minutes before serving. This resting time allows the filling to settle and thicken slightly, making the rollups easier to handle and preventing the creamy center from spilling out when you cut into them.
