Cheesy Scalloped Potatoes
How to make the best scalloped potatoes—EVER:
- 6 slices bacon, chopped into 1" pieces
- 3 tbsp. butter
- 3 garlic cloves, minced
- 3 tbsp. all-purpose flour
- 2 c. heavy cream
- 1 c. low-sodium chicken broth
- 2 lb. russet potatoes, rinsed and scrubbed clean
- 2 c. shredded cheddar
- ¼ c. finely chopped chives
- kosher salt
- Freshly ground black pepper
- Preheat oven to 400°. In a large skillet over medium heat, cook bacon until crispy, about 8 minutes. Drain on paper towels.
- In another large skillet over medium heat, melt butter. Add garlic and cook until fragrant, about 1 minute. Stir in flour and cook for another minute. Whisk in cream and chicken broth and season with salt and pepper. Simmer until thickened slightly, about 5 minutes. Remove from heat.
- Peel potatoes and thinly slice each potato crosswise into thin coins. (A mandolin would work great here.)
- Spoon a thin layer of sauce into the bottom of a large casserole dish. Add a single layer of potatoes on top. Spoon more sauce over the potatoes and top with cheese and bacon. Repeat 3 to 4 times, or until the casserole dish is mostly full.
- Bake until the sauce is bubbly and the potatoes are very tender, about 1 hour 15 minutes. Let rest for at least 15 minutes before serving.
