Ingredients You’ll Need for Garlic Potato Gratin

To create this delicious Garlic Potato Gratin, you’ll need the following ingredients:

3 lb Yukon Gold Potatoes: These potatoes are perfect for gratin due to their buttery texture and great flavor. They hold their shape well when baked.
1 large garlic head: Roasting garlic brings out its sweetness, making it a perfect addition to the creamy mixture.
1 cup whole milk: Adds creaminess to the dish. You can use low-fat milk, but whole milk gives the best flavor.
1/4 cup heavy cream: This ensures that your gratin is luxuriously rich. If you want to skip it, slightly increase the amount of milk.
6 oz cream cheese: This ingredient contributes to that delightful creamy layer. Just make sure you’re using a regular (non-light) cream cheese.
1/4 tsp nutmeg: A pinch of nutmeg enhances the warmth and complexity of the dish without overwhelming it.
1/4 tsp smoked paprika: This brings a subtle smokiness that pairs beautifully with the garlic.
1/2 tsp dried parsley: A hint of herbiness, parsley freshens up the richness of the gratin.
1/2 tsp onion powder: This adds depth without having to chop onions.
2 cups Gruyere cheese, grated: The melted Gruyere adds a nutty and tangy quality to the dish, making it incredibly flavorful.
1/2 cup Parmigiano Reggiano, grated (+ more for topping): This cheese gives a lovely salty kick and a crispy topping when baked.
1 tsp butter: For greasing your baking dish, so the gratin doesn’t stick.
Chives, to taste, for topping: These provide a fresh pop of color and flavor to finish off your dish.
Salt and pepper, to taste: Essential for seasoning.

Substitutions and Shortcuts:

If you’re missing some of these ingredients, don’t worry! You can substitute the Gruyere with another cheese like Fontina or even Cheddar. For the cream cheese, you might use mascarpone or sour cream. Whole milk can be swapped for a plant-based milk, though avoid almond milk for this recipe due to its flavor. And if you don’t have chives, scallions provide an excellent alternative.

How to Make Garlic Potato Gratin Step-by-Step

Now, let’s dive into the heart of the operation—the preparation of your Garlic Potato Gratin. This section will guide you through every step, ensuring your success.

Prepare the Roasted Garlic: Start by preheating your oven to 375°F (190°C). Take a head of garlic and cut off the top, exposing the individual cloves. Drizzle some olive oil over it, then wrap the garlic snugly in aluminum foil. Place the package directly on the oven rack and roast for about one hour. The cloves will become soft and sweet, making the gratin incredibly flavorful.
Blend the Cream Mixture: After the garlic has roasted and cooled enough to handle, squeeze the softened cloves out into a mixing bowl or blender. Add the cup of whole milk, 1/4 cup of heavy cream, 6 ounces of cream cheese, 1/4 cup of Gruyere cheese, the grated Parmigiano Reggiano, nutmeg, smoked paprika, dried parsley, and onion powder. Blend until smooth and creamy. The mixture should be thick yet pourable—this will be your rich sauce that brings the entire dish together.
Slice the Potatoes: Meanwhile, while the garlic is roasting, wash and peel the Yukon Gold potatoes. Slice them thinly—aim for about 1/8th of an inch thick. You want them thin enough to cook through, but not paper-thin, so they hold their shape during the baking.
Layer the Baking Dish: Butter a large baking dish, ensuring it’s greased thoroughly to prevent sticking. Begin layering the potato slices in the bottom of the dish, fanning them out for an even distribution. After layering, drizzle about a third of the cream mixture over the potatoes. Follow up by sprinkling a generous handful (about 1/2 cup) of the remaining Gruyere cheese on top. Repeat this process until you reach the final layer of potatoes.
Bake the Gratin: Cover the baking dish with aluminum foil and place it in the middle rack of your oven preheated to 400°F (204°C). Bake for 45 minutes—the foil will help steam the potatoes, making them tender. After 45 minutes, carefully remove the foil and return it to the oven to bake uncovered for an additional 15 to 20 minutes. This final step is crucial, as the gratin will turn golden and bubbly.
Finishing Touches: Once it’s cooked, take the dish out of the oven and let it cool for a few minutes. This will allow the layers to settle and make serving easier. Before serving, sprinkle freshly chopped chives, black pepper, and extra grated Parmigiano on top for a finishing touch.

Common Mistakes to Avoid

When making Garlic Potato Gratin, there are a few common pitfalls that can turn your culinary adventure into a little disaster. Here are some tips to ensure that doesn’t happen!

1. Not Preheating the Oven

This might sound basic, but it’s crucial. If you don’t preheat your oven, your potatoes may not cook evenly, leading to a mushy or undercooked dish. Always make sure your oven is at the right temperature before you put the gratin in.

2. Overslicing the Potatoes

Slicing your potatoes too thin can lead to a mushy texture. The ideal thickness is about 1/8th of an inch. Use a mandoline for uniform slices if you’re comfortable with one, but a good sharp knife works fine, too.

3. Forgetting to season

Don’t skimp on the salt and pepper! Season each layer of potatoes and the cream mix well, as it’s easy to overlook that step in larger recipes. A little salt will draw out the flavors of these ingredients and elevate the dish.

Serving Suggestions for Garlic Potato Gratin

Garlic Potato Gratin can stand alone as a comforting meal, but it shines even brighter when paired with other dishes. Here are some serving suggestions:

1. Pair with a Fresh Salad

A bright, fresh salad pairs beautifully with the richness of the gratin. Consider a simple green salad with mixed greens, cherry tomatoes, and a light vinaigrette. The acidity of the dressing will cut through the creaminess and cleanse the palate.

2. Serve with Roasted Vegetables

Roasted vegetables make an excellent side dish alongside Garlic Potato Gratin. Try mixing seasonal vegetables such as carrots, brussels sprouts, or zucchini, tossed with olive oil, salt, and herbs, then roasted until tender.

3. Add a Protein

For a complete meal, consider adding a protein. A roast chicken or pan-seared fish would complement the flavors well without overpowering them. A light, herb-marinated chicken would work wonders!

Conclusion
