If you have time, season the chicken thighs with a pinch of salt and pepper. A quick sear in a skillet with a little oil adds flavor, but it’s perfectly okay to skip and place the chicken straight into the slow cooker.
In the slow cooker, whisk together the chicken broth, soy sauce (if using), garlic, onion, oregano, and paprika. This is your base—simple, comforting, and ready for the cooker.
Add the rinsed rice to the broth, giving it a gentle stir to coat the grains. Layer the chicken thighs on top, skin side up. They’ll baste the rice as they cook, keeping things moist.
Sprinkle the frozen vegetables around the sides—no need to thaw. Cover and cook on low for about 6 to 7 hours, or on high for 3 to 4 hours, until the chicken reaches 165°F (74°C) and the rice is tender.
If the mixture seems too liquid at the end, remove the lid and let it sit for 5–10 minutes. A quick stir will help the rice finish absorbing some of that sauce.
Taste and adjust with a little extra salt or pepper if needed. Serve hot, with a simple green salad or steamed greens on the side for balance.
