Heat olive oil in a large skillet over medium-high heat.
Add ground turkey and diced onion; cook while breaking up the meat until browned and onion is translucent.
Stir in minced garlic, thyme, smoked paprika, salt, and pepper, cooking for 60 seconds.
Add shredded Brussels sprouts to the skillet and toss to incorporate with the turkey.
Deglaze the pan with apple cider vinegar and chicken broth.
Cover the skillet and steam for 5 minutes until sprouts are tender.
Remove the lid and sauté for 2 additional minutes to evaporate excess liquid and slightly caramelize the sprouts.
