Season the chicken breasts with salt, pepper, garlic powder, and onion powder on both sides.
In a skillet, heat the olive oil over medium heat. Sear each chicken breast for about 3-4 minutes on each side until lightly browned.
Place the seared chicken in the crockpot and pour in the chicken broth.
In a small bowl, mix together the heavy cream and chopped sun-dried tomatoes, then pour over the chicken in the crockpot.
Cover the crockpot and cook on low for 4-6 hours or high for 2-3 hours, until the chicken is cooked through and tender.
About 30 minutes before serving, add the fresh spinach and shredded parmesan cheese into the crockpot. Stir gently and let it finish cooking until the spinach wilts and cheese melts.
Once cooked, serve the chicken and sauce over a bed of cauliflower rice or zucchini noodles for a complete keto meal.
