Heat olive oil in a large pot over medium heat. Add diced onions, carrots, and celery. Sauté for 5-7 minutes until softened.
Cook The Chicken Sausage
Add sliced chicken sausage to the pot. Stir occasionally, cooking until the sausage begins to brown, about 5 minutes.
Add Garlic And Seasonings
Add minced garlic, thyme, and paprika. Stir and cook for about 1 minute until fragrant.
Pour In The Broth And Tomatoes
Add the chicken broth and diced tomatoes (with juice) to the pot. Stir everything together, scraping up any bits from the bottom.
Simmer And Cook The Rice
Bring the soup to a simmer. Add the uncooked rice, reduce the heat to low, and cover the pot. Let it simmer for 15-20 minutes, or until the rice is tender.
Adjust Seasoning And Serve
Once the rice is cooked, taste the soup and adjust the seasoning with salt and pepper. Garnish with fresh parsley if desired. Serve hot.
Notes
I like to make a double batch of this soup and freeze it in portions for easy weeknight dinners. It freezes well, and the flavors deepen even more when reheated.
