This oven baked 3-ingredient bacon fat roasted potatoes recipe is straight from my grandfather’s playbook. He swore that the secret to truly crispy potatoes was using bacon fat instead of oil, and after watching him make these on Sunday mornings my whole childhood, I’m convinced he was right. With just potatoes, bacon fat, and salt, you get deeply browned, shatteringly crisp edges and a fluffy center—no fancy techniques or extra ingredients. It’s the kind of simple, practical side dish you can throw together on a busy weeknight but still feels special enough for a holiday table.
These potatoes are perfect next to roast chicken, grilled pork chops, or a simple seared steak. I like to pile them into a white serving bowl, set them in the middle of the table, and let everyone help themselves. They’re also great with eggs for a weekend brunch, or alongside a big green salad when you want something comforting but easy. A dollop of sour cream, a sprinkle of fresh herbs, or a side of ketchup or hot sauce all work well if you want to dress them up a bit.
Bacon Fat Roasted PotatoesServings: 4
Ingredients
2 pounds russet potatoes, scrubbed and cut into 1-inch chunks
4 tablespoons bacon fat (rendered from cooked bacon), melted
1 1/4 teaspoons kosher salt, plus more to taste
Directions
Preheat your oven to 425°F (220°C). Place a large, heavy sheet pan (metal, not glass) on the middle rack while the oven heats so the pan gets hot.
While the oven preheats, prep the potatoes: scrub them well and cut into roughly 1-inch chunks, trying to keep the pieces similar in size so they cook evenly. Pat the potatoes very dry with a clean kitchen towel or paper towels—this helps them crisp instead of steam.
In a large bowl, toss the potato chunks with the melted bacon fat and kosher salt until every piece is well coated and glossy. Take a moment to scrape the bowl and make sure no potato is left dry; the even coating of bacon fat is what gives you that deep golden, crispy exterior my grandfather loved.
Carefully remove the hot sheet pan from the oven and immediately spread the potatoes out in a single, even layer. They should sizzle a bit when they hit the pan. Make sure there is a little space between pieces so they can crisp instead of crowding and steaming.
Roast the potatoes for 20 minutes without stirring, letting the bottoms get deeply browned. After 20 minutes, use a thin spatula to flip and turn the potatoes, scraping up any browned bits from the pan and rotating them so new sides make contact with the hot metal.
Return the pan to the oven and roast for another 15–20 minutes, flipping once more if needed, until the potatoes are deeply golden brown on most sides and the edges are very crisp. Total roasting time will be about 35–40 minutes, depending on your oven and the size of the pieces.
Taste a potato and sprinkle with a little more salt if needed. Transfer the hot, crispy potatoes to a white serving bowl and serve right away while the outsides are still crackly and the centers are fluffy. If you’re juggling other dishes, you can keep them warm in a low oven (around 200°F/95°C) for 10–15 minutes, but they’re best fresh out of the oven.
Variations & Tips
If you like a little extra flavor without adding more main ingredients, you can play around with finishing touches. After roasting, toss the hot potatoes with a pinch of black pepper, smoked paprika, or garlic powder. Fresh herbs like chopped parsley or chives are great sprinkled on just before serving and won’t fight with the simple bacon-and-potato flavor. To save time on busy nights, you can cut the potatoes earlier in the day, store them in cold water in the fridge, then drain and dry them really well before tossing with bacon fat and salt. If you don’t have enough saved bacon fat, you can supplement with a little neutral oil, but the flavor and crispness are best when most of the fat is from bacon. For extra-crispy edges, lightly rough up the cut potatoes after drying by shaking them in a colander for a few seconds before tossing with the bacon fat—this creates more surface area that turns golden and crunchy in the oven.
