Season the chicken thighs with salt, pepper, and paprika.
In a large skillet, heat olive oil over medium-high heat.
Dredge each chicken thigh in flour, shaking off excess.
Brown the chicken thighs in the skillet for about 5-7 minutes per side.
Remove chicken from the skillet and set aside.
Add sliced onions and minced garlic to the skillet, sauté until softened.
Pour in chicken broth, scraping the bottom to deglaze the pan.
Return chicken thighs to the skillet, cover, and reduce heat to low.
Simmer for about 30 minutes until chicken is cooked through.
Stir in butter and thyme before serving, allowing the sauce to thicken.
