Season the pork chops with salt and black pepper on both sides.
In a large skillet, heat olive oil over medium-high heat.
Sear the pork chops for about 3-4 minutes on each side until browned. Remove from heat and set aside.
In the Crock-Pot, layer the sliced onions and minced garlic at the bottom.
Add the potato chunks on top.
Pour in the chicken broth, then sprinkle the dried thyme, paprika, and red pepper flakes (if using) over the potatoes.
Place the seared pork chops on top of the potatoes.
Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the pork is tender and cooked through.
If using, add the frozen peas during the last 30 minutes of cooking. Stir gently before serving.
