Season the chicken breasts with salt and pepper on both sides.
Add the olive oil to a pan over medium heat on the stove. Then, add the chopped shallot and crushed garlic to the pan. Sauté the shallot and garlic for about 2 minutes. From there, move the shallot and garlic to one side of the pan.
Sear the seasoned chicken breasts in the pan for about 2-3 minutes on each side. While searing, sprinkle the onion powder and Italian seasoning over the chicken.
Place the seared chicken in the slow cooker. Then, add the chopped sun-dried tomatoes, low-sodium chicken broth, and optional chili crunch oil or a pinch of red pepper flakes.
Place the lid on the slow cooker and cook everything on low for 4-6 hours, or until the chicken is fully cooked and reaches an internal temperature of 165°F.
About 30 minutes before serving, prepare a cornstarch slurry by mixing the cornstarch with two tablespoons of cold water. Stir the cornstarch slurry into the slow cooker to thicken the sauce. Let everything cook on low for 30 minutes to thicken the sauce.
When ready to serve, turn off the slow cooker and remove the chicken. Before adding the grated Parmesan and blended cottage cheese, it's important to stop the cooking process to lower the overall heat. This helps ensure that the sauce isn’t too hot, which could cause the cottage cheese to separate. Once the heat has reduced, stir in the Parmesan and cottage cheese, mixing well until smooth. Then, coat the chicken in the sauce and pour the remaining sauce over the chicken.
