  • 10 oz spaghetti pasta
  • 2 chicken breasts ~1-1.5 lbs
  • 40 oz diced tomatoes canned
  • 2 cups chicken broth
  • 6 oz mascarpone cheese
  • 2 cups mozzarella shredded
  • 1 1/2 tsp basil
  • 1 tsp oregano
  • 1/2 tsp marjoram
  • 1-2 tsp olive oil
  • 1 tbsp garlic minced
  • salt to taste


  • Using a crockpot, cook chicken and chicken broth on high for 3 hours. Add enough chicken broth to cover over half of the chicken (no need to completely submerse chicken). 
  • Remove chicken breasts and shred them using a fork, then bring it back to cook on low in crockpot for 30 minutes.
  • Cook spaghetti pasta in a pot for 8-9 minutes, or two minutes less than package recommendation. Drain and set aside.
  • In a pot, sauté minced garlic in olive oil for 30 seconds. Do not over-brown or burn garlic.
  • Add diced tomatoes, mascarpone cheese, 3/4 cup of cooked chicken broth from the crockpot (without the chicken), basil, oregano, and marjoram.
  • Bring to boil, then cook on medium low heat for 10-15 minutes. Add 1/3 cup (packed) of shredded mozzarella cheese. Liquid should thicken slightly. If you like the liquid thicker, add another 1/4 cup (or more) of shredded mozzarella cheese. Keep in mind that liquid will thicken more after adding the more items. Add salt to taste.
  • Remove from heat and add shredded chicken (drained) and cooked spaghetti into the sauce. Mix well. Then pour everything into a 9"x13" casserole dish.
  • Sprinkle the rest of the shredded mozzarella onto the top of the casserole dish.
  • Broil casserole dish in oven for 3-4 minutes until the cheese on the top of the casserole is browned.
  • Remove from oven and cool for 10 minutes. Serve and enjoy!
