Place baby potatoes in a large pot, cover with water, add salt, and boil until tender, about 12–15 minutes.
Drain the potatoes and set aside.
Melt butter in a large skillet over medium heat.
Add minced garlic and sauté until fragrant, about 1–2 minutes, avoiding browning.
Pour in heavy cream and stir to combine.
Add grated Parmesan and dried thyme or rosemary, simmer gently for 3–5 minutes until sauce thickens slightly.
Season sauce with salt and black pepper to taste.
Add cooked potatoes to the skillet and toss to coat evenly in the sauce.
Cook for an additional 2–3 minutes until heated through.
Serve warm, garnished with fresh parsley or chives if desired.
