Pat the lamb chops dry with paper towels. Place them in a large bowl.
Rub ½ teaspoon salt over all sides of the chops. Set aside for 20 to 30 minutes in the fridge.
In a large bowl, place olive oil, tomato paste mixed with a little water, garlic, thyme, chili flakes, 1 teaspoon salt, and pepper.
Mix well and add the salted chops.
Rub the marinade evenly over all sides of the chops.
Set them aside on a plate for another 20 to 30 minutes at room temperature. This short rest lets the flavors soak into the meat. Keep the rest of the marinade for vegetables.
Peel the potatoes and cut them into thick slices. Slice the tomatoes into thick rounds or cut them into wedges. Halve or slice the Turkish peppers.
Rub the prepared vegetables with the rest of the marinade from the lamb chops.
Spread the potato wedges on the bottom of your oven dish. Layer the peppers on top of the potatoes.
Place the seasoned lamb chops on top of the vegetables and arrange the tomato wedges in between chops. Pour any leftover seasoning mixture from the bowl over the top.
Spread everything evenly so the lamb cooks over the vegetables. Preheat your oven to 180 ℃ - 356 ℉.
Cover the pan loosely with foil to keep the lamb juicy. Bake for about an hour.
Remove the foil and continue baking another 15 to 20 minutes until the potatoes are soft and the lamb reaches your preferred doneness. If you use a meat thermometer, aim for around 60 ℃ - 140 ℉ for medium.
Remove the pan from the oven. Cover again loosely with foil and let the lamb rest for about 10 minutes.
Serve the lamb chops with the roasted potatoes, peppers, and tomatoes, spooning over the pan juices for extra flavor.
