Peel and quarter the potatoes, then place them on a microwave-safe plate, covering with a microwave lid.
Microwave for 3 1/2-4 1/2 minutes.
Once the knife slides through with some resistance, allow them to cool to room temperature.
You can refrigerate them overnight and dice them into 1/2-inch pieces before using.
In a 12-inch skillet, heat butter, olive oil, rosemary, thyme, and smashed garlic clove over medium-high heat until the herbs sizzle.
Remove and discard the herbs and garlic.
Add the diced potatoes, season with salt, pepper, cayenne, garlic powder, onion powder, and smoked paprika.
Toss to coat and cook for 8-10 minutes, flipping every 2-3 minutes until golden.
Adjust seasoning to taste and serve immediately.
