Instructions
Heat olive oil in a large pot over medium-high heat until shimmering.
Add chicken pieces, season with salt and pepper, and cook until browned on all sides, about 5 minutes.
Transfer chicken to a plate. Add onion, carrots, and celery to the pot; cook, stirring occasionally, until vegetables soften, 4–5 minutes.
Stir in garlic, thyme, oregano, red pepper flakes, and tomato paste; cook until fragrant, about 1 minute.
Add rice and chicken broth; bring to a gentle simmer. Cover, reduce heat to low, and cook until rice is tender, about 18 minutes.
Return chicken to the pot and simmer until heated through, about 2 minutes.
Stir in spinach until wilted, then sprinkle parsley over the top and serve.
Notes
Testing note: Rinsing the rice until the water runs clear results in a cleaner, less starchy broth.Testing note: Letting the browned chicken rest on a warm plate while the vegetables cook helps prevent overcooking.Testing note: Freezing the soup in 2-cup portions ensures even reheating and preserves texture.
