My sister made this 3 ingredient side dish for Sunday dinner and I have been dreaming about it ever since

My sister brought this simple little side dish to Sunday dinner one week, and I honestly have been thinking about it ever since. It’s the kind of recipe you pull out when you’re tired, hungry, and still want something that tastes special without a lot of fuss. Just three ingredients—potatoes, Dijon mustard, and a bit of oil—come together in the oven to make golden, crispy wedges with a tangy, savory glaze that clings to every edge. It’s very much a small-town, family-style dish: practical, budget-friendly, and perfect for sliding into the oven while the rest of dinner comes together.

These Dijon potato wedges are wonderful with simple roasted chicken, pork chops, or grilled sausages, and they’re just as at home next to burgers or meatloaf. I like to put them right on the table in the foil-lined pan so everyone can grab the crispiest pieces. A green salad, steamed green beans, or roasted broccoli rounds out the plate nicely. For dipping, set out a little extra Dijon, ketchup for the kids, or a quick mix of mayo and mustard for something creamy. They’re also great at brunch alongside scrambled eggs and bacon.

Servings: 4

2 pounds russet or yellow potatoes, scrubbed and cut into thick wedges

Preheat your oven to 425°F (220°C). Line a large baking sheet with aluminum foil for easy cleanup, and lightly crumple the foil, then flatten it back out so the wedges have little ridges to sit on. This helps them crisp up and also matches that homey, slightly rustic look.

Scrub the potatoes well under cool running water. Leave the skins on for extra texture and flavor. Pat them dry with a clean kitchen towel or paper towels, then cut each potato into thick wedges—usually 8 wedges per medium potato.

In a large mixing bowl, whisk together the Dijon mustard and vegetable oil until the mixture is smooth and glossy. It should look like a loose, shiny dressing.

Add the potato wedges to the bowl. Use clean hands or a spatula to toss until every wedge is well coated in the Dijon-oil mixture. Take a moment to really work the mixture into the potatoes so the mustard clings to the sides and edges.

Spread the coated potato wedges out in a single layer on the foil-lined baking sheet. Make sure they are not piled on top of each other; give them a little breathing room so they roast instead of steam. Turn any pieces that look under-coated so the mustard side is facing up for the best color and shine.

Place the baking sheet on the middle rack of the preheated oven. Bake for 25–30 minutes, then carefully remove the pan and use a spatula or tongs to flip the wedges so a new side is touching the foil. This helps all the edges get crispy and browned.

Return the pan to the oven and bake for another 10–15 minutes, or until the wedges are deep golden brown with crispy edges and the mustard glaze looks slightly shiny and set. The insides should be tender when pierced with a fork.

When they’re done, let the potato wedges rest on the pan for 3–5 minutes. This quick rest helps the exterior firm up a bit more and makes them easier to remove from the foil. Serve them straight from the pan or transfer to a platter, scraping up any little crispy, mustardy bits to spoon over the top.

If your family likes a little extra flavor, you can sprinkle the coated wedges lightly with salt and pepper right before baking, though the Dijon already adds a nice savory punch. For kids or picky eaters who might be unsure about mustard, use a milder Dijon or mix half Dijon and half regular yellow mustard to soften the tang. You can also cut the potatoes into smaller fries instead of wedges; just shorten the baking time and keep an eye on them so they don’t burn. For a slightly richer version, drizzle an extra teaspoon of oil over the wedges halfway through baking to help deepen the browning. If you’d like a bit of herb flavor without adding more ingredients to the coating, serve the finished wedges with a sprinkle of dried parsley or chives at the table. Food safety tips: Always wash and scrub potatoes well to remove dirt before cooking, and cut away any green spots or deep eyes. Use a sharp knife and a stable cutting board to prevent slips when cutting wedges. Make sure the potatoes are cooked until tender all the way through (a fork should slide in easily) to avoid an underdone, starchy texture. Let the baking sheet cool slightly before moving it or tearing off the foil to avoid steam burns, and keep hot pans out of reach of children. Leftover wedges should be cooled, then stored in a covered container in the refrigerator and eaten within 3–4 days; reheat in a hot oven or air fryer to bring back some crispness.
