Crispy Parmesan Potato Gratin Ingredients
• Discover the delicious elements of this crispy Parmesan classic.
For the Creamy Base
- Heavy Cream – Provides richness and creaminess; substitute with half-and-half for a lighter option.
- Kosher Salt – Enhances flavor; sea salt works if kosher is not available.
- Garlic (3 cloves, minced) – Adds aromatic depth; fresh garlic is best for stronger flavor.
- Butter (1 tbsp) – Adds richness and helps caramelize shallots.
- Shallot (1 small, diced) – Contributes sweetness and flavor; you can swap with yellow onion if needed.
For the Potatoes
- Yukon Gold/White Potatoes (5 medium) – Provides texture and flavor; keeping the skin on adds nutrients.
For the Cheese Topping
- Gruyere Cheese (1 cup, grated) – Melts beautifully and introduces a nutty flavor; feel free to try Fontina or Emmental instead.
- Parmesan Cheese (1/2 cup, grated) – Complements Gruyere with its salty depth; Pecorino Romano can serve as a substitute.
For the Finishing Touch
- Fresh Thyme (1 tsp) – Infuses herbal notes; dried thyme is also a great alternative if fresh isn’t on hand.
Step‑by‑Step Instructions for Crispy Parmesan
Step 1: Preheat the Oven
Begin by preheating your oven to 325°F (163°C). This slow and steady temperature will ensure that your crispy Parmesan potato gratin bakes evenly. Preheating is essential for achieving that golden, bubbly top we all crave. While the oven warms up, gather your ingredients and equipment, including a 12-inch cast-iron skillet and a small saucepan.
Step 2: Prepare the Cream Mixture
In a small saucepan, combine heavy cream, kosher salt, and three cloves of minced garlic. Over low heat, simmer this mixture gently for about five minutes, allowing the garlic to infuse its aromatic flavor into the cream. Stir occasionally for even blending, then remove from heat and set aside to cool slightly as you prepare the potatoes.
Step 3: Slice the Potatoes
Using a mandoline slicer, thinly slice five medium Yukon Gold potatoes to about 1/8 inch thickness. This ensures a uniform cook and perfect texture for your crispy Parmesan potato gratin. Arrange the slices neatly on a baking sheet for easy access, avoiding any browning while you move on to the next step.
Step 4: Sauté the Shallots
In your cast-iron skillet, melt one tablespoon of butter over low heat. Add the diced shallot and sauté for approximately five minutes, stirring frequently, until the shallots become soft and caramelized. This step builds a sweet base flavor that beautifully complements the creamy potatoes in your gratin.
Step 5: Layer the Potatoes
Once the shallots are ready, start layering the potato slices in a spiral pattern over the caramelized shallots in the skillet. This technique not only looks appealing but also ensures even cooking throughout the dish. Ensure the potato layers are snug and evenly distributed for the best final result in your crispy Parmesan potato gratin.
Step 6: Add the Cream Mixture
Pour the infused cream mixture evenly over the neatly arranged potatoes, ensuring that every slice is well-coated. This creamy base is pivotal to the rich texture and flavor that defines your crispy Parmesan potato gratin. Use a spoon to help any cream seep through the layers for an even bake.
Step 7: Bake Covered
Cover the skillet tightly with tin foil and place it in the preheated oven. Bake for one hour and 15 minutes, allowing the potatoes to tenderize and absorb the flavors from the cream and garlic. Check towards the end of the bake time; the potatoes should be soft when pierced with a fork.
Step 8: Broil for Crispiness
After the initial bake, carefully remove the foil and switch your oven to the broil setting. Generously sprinkle one cup of grated Gruyere and half a cup of grated Parmesan cheese on top of the potatoes, followed by fresh thyme. Broil for about five minutes, keeping a close eye on it until the cheese is golden and bubbly, achieving that coveted crispiness.
Step 9: Serve Warm
Once the cheese is perfectly browned, remove the skillet from the oven and let it sit for a few minutes. This brief resting time allows the layers to settle. Serve your crispy Parmesan potato gratin warm, and enjoy a delightful plate of creamy, cheesy goodness that’s sure to impress both family and friends!
