Oven Baked 3-Ingredient Lard and Onion Potato Scallop

There are some dishes that feel like a warm hug from a farmhouse kitchen, and this Oven Baked 3-Ingredient Lard and Onion Potato Scallop is exactly that. It is humble, golden, and deeply comforting, with tender layers of potatoes and sweet onions baked in rich, savory lard until the edges turn crisp and the center turns silky. It is old-fashioned cooking at its best, and it proves that a short ingredient list can still create something unforgettable.

What I love most about this recipe is how the lard transforms simple potatoes. It adds a savory depth and a beautiful golden crust that butter or oil just cannot match. The onions melt into the layers, becoming soft and sweet, while the potatoes soak up all that richness. It is the kind of side dish that makes a plain roast chicken or pork chop dinner feel like a Sunday supper.

It is also wonderfully forgiving. You can bake it in a cast-iron skillet, a casserole dish, or a Dutch oven, and it comes out delicious every time. Serve it hot from the oven, when the top is crisp and the inside is creamy.

Why You’ll Love This Recipe

This dish is the definition of simple, old-fashioned comfort food. With just three main ingredients, it is budget-friendly, forgiving, and perfect for busy days when you want something warm without a lot of fuss.

The texture is unforgettable. The potatoes get tender and creamy, the onions caramelize into sweetness, and the lard creates a golden, crispy top and bottom.

Ingredients

3 pounds russet or Yukon Gold potatoes, peeled and thinly sliced
2 large yellow onions, thinly sliced
1/2 cup lard, melted, plus more for greasing

Salt and black pepper are considered free pantry staples and can be added to taste. Water or broth can be added if needed.

Directions

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or cast-iron skillet generously with lard.
Layer half the potatoes in the bottom of the dish. Scatter half the onions over the potatoes. Season with salt and pepper. Drizzle with about 2 tablespoons of melted lard.
Repeat with the remaining potatoes, onions, and another drizzle of lard. Season the top.
Pour 1/2 cup water or broth around the edges if you want a more tender, spoonable scallop.
Cover tightly with foil and bake for 45 minutes.
Remove the foil and bake for another 25 to 35 minutes, until the potatoes are fork-tender and the top is deeply golden and crisp.
Let rest for 10 minutes before serving.

Variations

Cheesy Potato Scallop: Sprinkle 1 1/2 cups shredded cheddar between the layers.
Herb Lard Scallop: Add 1 teaspoon dried thyme or rosemary to the melted lard.
Bacon Onion Scallop: Scatter cooked, crumbled bacon over the onions.
Garlic Lard Scallop: Add 2 minced garlic cloves to the melted lard.
Creamy Version: Pour 1 cup heavy cream over the layers before baking.

Expert Tips

Slice the potatoes evenly. A mandoline makes this quick and ensures even cooking.
Use enough lard. It is what gives the scallop its signature richness and crispy edges.
Season in layers. Every layer of potatoes and onions needs salt and pepper.
Cover first, then uncover. This steams the potatoes tender before crisping the top.
Let it rest. Resting helps the layers set and makes serving easier.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in a 375°F oven for 10 to 12 minutes to restore crispiness. Avoid the microwave, as it will make the potatoes soggy. This dish does not freeze well, as the texture can become grainy upon thawing.

Frequently Asked Questions

Can I use butter instead of lard? Yes, but the flavor and crispness will be different.
Can I use sweet potatoes? Yes. They work beautifully with the onions and lard.
Why are my potatoes still firm? They may have been sliced too thick or needed more time. Cover and bake longer.
Can I make this ahead of time? Yes. Assemble it, cover, and refrigerate for up to 24 hours. Add 10 minutes to the covered bake time.
Can I add cheese? Yes. Cheddar, Gruyère, or Parmesan all melt beautifully between the layers.
