Heat a heavy, oven-proof skillet over medium-high heat and add the bacon. Fry until crisp, drain on paper towels and set aside. Discard all but 1 tablespoon of the bacon fat.
Add the olive oil to the pan along with the potatoes and sauté for 3 to 4 minutes. Add the garlic and cook until fragrant, 1 minute longer. Season with salt and pepper.
Place the pan in the oven and roast until the potatoes are golden brown and tender, 12 to 15 minutes, stirring midway through the cooking time to ensure even cooking.
Remove from the oven, add the bacon and adjust the seasoning as needed. Allow to cool for 2 to 3 minutes, then add the blue cheese and toss to combine. Serve immediately.
Tips for Making This Recipe
For best results, choose a good quality, creamy blue cheese. When you toss a creamy blue with the hot potatoes, it melts a little and coats the potatoes, adding extra flavor and a little richness to the dish.
