Mother’s Day Parmesan Potatoes
A Midwestern-style comfort dish turned elegant. Thinly sliced potatoes slowly bathe in a simple Parmesan cream mixture until they reach a golden, spoon-tender perfection.
Ingredients
- 3 pounds russet potatoes, scrubbed and thinly sliced (1/8–1/4 inch)
- 2 cups heavy cream
- 1 1/2 cups finely grated Parmesan cheese (divided)
- 1 1/2 teaspoons kosher salt (plus more to taste)
Directions
- Prep the Slow Cooker: Lightly grease a 5- to 6-quart oval slow cooker insert with butter or oil to prevent sticking.
- Slice the Potatoes: Scrub potatoes and pat dry. Using a sharp knife or mandoline, slice into even rounds (1/8–1/4 inch thick). Leaving skins on adds texture, but you may peel them for a smoother look.
- Whisk the Sauce: In a medium bowl, whisk together the heavy cream, 1 cup of Parmesan, and salt until smooth.
- Layering: Arrange one-third of the potatoes in the bottom, overlapping like shingles. Drizzle with one-third of the cream mixture. Repeat this process two more times, finishing with a layer of potatoes. Press down gently to settle the slices.
- Slow Cook: Cover and cook on LOW for 4 1/2 to 5 1/2 hours. Avoid lifting the lid during the first few hours to keep the heat consistent.
- The Finish: 20–30 minutes before serving, sprinkle the remaining 1/2 cup of Parmesan on top. Cover and continue cooking until the cheese is melted and glossy.
- Rest: Turn the slow cooker to WARM and let sit for 10–15 minutes. This allows the sauce to thicken into a velvety glaze before serving.
How to Serve: Garnish with fresh chives or green onions. These are beautiful alongside baked ham, roasted chicken, or a brunch frittata. Pairs perfectly with dry sparkling wine or iced tea with lemon.
Variations & Kitchen Tips
- Lighter Version: Swap up to 1/2 cup of cream for whole milk (though the texture will be slightly less rich).
- Flavor Boost: Add a pinch of nutmeg or black pepper to the cream for a classic “Gratin” flavor profile.
- Grate your own: Use a high-quality, aged Parmesan and grate it finely for the smoothest melt.
Food Safety: Cook on LOW to ensure potatoes soften properly and reach a safe temperature. Do not leave on the WARM setting for more than 2 hours. Refrigerate leftovers in shallow containers and reheat until steaming hot.
