Ingredients

  • 8 oz spaghetti pasta
  • 1-2 tsp olive oil
  • 1 tbsp garlic minced
  • 28 oz canned diced tomatoes
  • 1 1/2 cup chicken broth
  • 8 oz mascarpone cheese
  • 2 cups mozzarella shredded
  • 1 1/2 tsp basil
  • 1 tsp oregano
  • 1/2 tsp marjoram
  • 3 cups cooked chicken diced or shredded
  • 1 tsp salt or to taste
  • 1/2 tsp black pepper or to taste

Instructions

  • Cook spaghetti pasta in a pot for two minutes less than package recommendation. Drain and set aside.
  • In a large skillet, sauté minced garlic in olive oil for 15-30 seconds under medium heat. Do not over-brown or burn garlic.
  • Add diced tomatoes, chicken broth, mascarpone cheese, basil, oregano, and marjoram. Mix to combine.
  • Bring to boil, then cook on medium low heat for 8-10 minutes to reduce liquid. Add cooked chicken, then add 1 cup of shredded mozzarella cheese. Liquid should thicken slightly. Keep in mind that liquid will thicken more after adding pasta. Add salt and black pepper.
  • Remove from heat and add 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.
  • Bake casserole dish in oven for 20 minutes until the cheese on the top of the casserole is bubbly.
  • Remove from oven. Serve and enjoy!

Notes

If using raw chicken, cook two pieces of raw chicken breast in boiling water for 10-12 minutes, or until internal temperature reached at least 165℉. Cube or shred chicken when it is done. Then follow the rest of the recipe instructions.
