Health Benefits

While this Cheese & Herb Potato Gratin is definitely a rich and indulgent dish, it still offers some surprising health benefits when enjoyed in moderation:

Potatoes: Both sweet potatoes and Yukon Gold potatoes provide essential vitamins and minerals. Sweet potatoes are rich in beta-carotene, which your body converts into vitamin A, essential for healthy vision and immune function. Yukon Gold potatoes offer potassium, vitamin C, and fiber.
Cheese: Gruyère and cheddar cheeses contain calcium and protein, important for bone health and muscle function. Choosing high-quality cheese can also enhance the overall flavor without needing to use a large quantity.
Herbs: The addition of thyme, sage, parsley, and rosemary not only adds incredible flavor but also brings antioxidants and anti-inflammatory properties. These herbs have been used for centuries for their potential health benefits.
Balanced Fats: Using whole milk or half-and-half provides a source of healthy fats that aid in the absorption of fat-soluble vitamins.
Broth Benefits: Using low-sodium chicken broth adds depth to the dish while keeping it relatively light. Opting for homemade broth can also provide essential nutrients like collagen.

Though it’s not a low-calorie dish, this gratin can be part of a balanced meal when enjoyed alongside a fresh salad or lean protein.

Ingredients List

Olive Oil: 1 tablespoon (for brushing the skillet)
Sweet Potatoes: 3 medium, peeled and sliced thinly (using a mandolin)
Yukon Gold Potatoes: 6 small, peeled and sliced thinly
Kosher Salt: 1 teaspoon
Ground Black Pepper: 1/4 teaspoon

Yellow Onion: 1/2 cup, thinly sliced and chopped
Whole Milk or Half-and-Half: 1/2 cup

Step-By-Step Cooking Instructions

Preparation:
- Preheat your oven to 375°F (190°C).
- Lightly brush the inside of a 10-inch cast-iron skillet or a 2-quart baking dish with olive oil. This prevents the potatoes from sticking and helps create a beautiful golden crust.
Slice the Potatoes:
- Peel the sweet potatoes and Yukon Gold potatoes.
- Slice them very thinly using a mandolin or sharp knife. Try to keep the slices uniform in thickness to ensure even cooking.
Combine Ingredients:
- In a large mixing bowl, gently toss the sliced potatoes with kosher salt, black pepper, garlic powder, thyme, sage, parsley, rosemary, and the grated cheese. Reserve about 1/2 cup of the cheese for topping later.
- Add the chopped onions to the mixture and gently combine.
Arrange in the Skillet:
- Take small handfuls of the potato mixture and line them up vertically in the prepared skillet or baking dish. Continue until all the potatoes are arranged neatly.
- Sprinkle the reserved cheese on top.
Add Liquid:
- Pour the whole milk and chicken broth evenly over the potatoes. This liquid helps cook the potatoes to a tender consistency and adds creaminess to the dish.
Bake:
- Cover the skillet tightly with foil and bake for 50 minutes.
- Remove the foil and bake for another 15-20 minutes until the potatoes are tender and the top is golden and bubbly.
Let It Rest:
- Allow the dish to cool for about 10 minutes before serving.

Pairing Suggestions

Choosing the right sides and drinks can elevate your Cheese & Herb Potato Gratin to another level. Here’s what works well:

Main Courses: Roasted chicken, beef tenderloin, or grilled lamb chops complement the rich flavors of the gratin.
Salads: A light arugula salad with lemon vinaigrette or a mixed green salad with balsamic dressing works well.
Vegetables: Serve with steamed green beans, roasted Brussels sprouts, or sautéed spinach.
Beverages: For non-alcoholic options, try sparkling water with lemon or herbal iced tea.
Bread: A crusty baguette or warm dinner rolls are perfect for soaking up the creamy, cheesy goodness.

Storage, Freezing & Reheating Instructions

Making this dish ahead or storing leftovers is a breeze. Here’s how:

Storage:

Allow the gratin to cool completely before transferring it to an airtight container.
Store it in the refrigerator for up to 3 days.

Freezing:

To freeze, place the cooked and cooled gratin in a freezer-safe container.
Freeze for up to 3 months.
When ready to use, thaw overnight in the refrigerator.

Reheating:

Preheat the oven to 350°F (175°C).
Place the gratin in an oven-safe dish and cover with foil.
Heat for about 20-30 minutes, or until warmed through.

The key is reheating it gently to maintain its creamy texture and avoid drying it out.

Common Mistakes to Avoid

To make sure your gratin turns out perfectly every time, avoid these common mistakes:

Overlapping Potatoes Too Tightly: Stacking the potato slices too tightly can prevent even cooking. Arrange them loosely for better results.
Skipping the Foil: Baking the gratin covered for the first part of cooking is essential for tender potatoes. Only uncover during the last stage to achieve that golden, crispy top.
Using Too Much Liquid: Adding more milk or broth than needed can make the gratin soupy. Stick to the recommended measurements.
Not Preheating the Oven: Always preheat the oven to ensure even cooking and perfect texture.
Forgetting to Let It Rest: Letting the dish cool slightly before serving allows the flavors to meld and the cheese to set properly.

Pro Tips

Make your gratin even better with these helpful tips:

Use Fresh Herbs When Possible: While dried herbs work well, fresh herbs provide a more vibrant flavor. Just remember to increase the quantity when using fresh.
Shred Your Own Cheese: Pre-shredded cheese often contains anti-caking agents that can affect melting. Grating your own cheese results in a smoother, creamier texture.
Use a Mandolin: For best results, use a mandolin to achieve thin, even potato slices. This ensures they cook uniformly.
Mix Cheese Types: Combining Gruyère with sharp white cheddar gives you the best of both worlds—nutty, creamy, and sharp flavors.
Make It Ahead: You can assemble the dish and refrigerate it up to a day before baking. Just bring it to room temperature before popping it in the oven.
