Looking for a quick, flavorful side? These roasted diced potatoes come out crispy on the outside and tender inside, with plenty of flavor from a simple spice mix. This recipe is sized for two but scales easily for family meals or meal prep.
I love easy, freezer-friendly dinners, and a fast roasted potato side is a staple to pair with chicken, pork, burgers, or meatloaf. Because the potatoes are diced into small, uniform pieces, they roast quickly and develop crisp edges while staying soft inside. For this batch I added lemon juice and Dijon mustard to complement a lemon chicken main, but you can leave those out for a classic olive oil and herb approach.
Why You’ll Love These Roasted Diced Potatoes
- Crispy on the Outside, Tender Inside: High heat roasting produces a golden crust while keeping the center fluffy.

- Customizable: Swap seasonings to match your main dish—everything from classic herbs to spicy blends works well.
- Perfect for Two (or More): The recipe is scaled for two but is easy to multiply for larger crowds.

Below are the ingredients for an easy batch that serves two. Adjust quantities to scale the recipe up or down.
- 5 small white potatoes, unpeeled, diced into 1½-inch cubes
- Juice of ½ a lemon (optional, for brightness)

How to Portion & Cook This Recipe
- Cooking for Two: Use about 4–5 small potatoes (roughly 5 small potatoes total in this recipe).
- Cooking for a Family: Plan on about 2 small potatoes per person and increase seasonings proportionally.
- Meal Prep Tip: Dice potatoes ahead and store submerged in cold water in the fridge for up to 24 hours to prevent browning. Ensure the pieces are fully covered.
Simple Instructions for Roasted Diced Potatoes
Follow these straightforward steps for crispy, flavorful potatoes.
- Preheat & Prep: Heat the oven to 450°F (230°C). Dice potatoes into roughly 1½-inch cubes, leaving skins on for texture and flavor.
- Make the Seasoning: In a mixing bowl, combine olive oil, lemon juice (if using), Dijon mustard (if using), rosemary-garlic seasoning, salt, pepper, and paprika. Stir well.
- Toss the Potatoes: Add the diced potatoes to the bowl and toss until every piece is evenly coated in the oil and spice mixture.
- Arrange on a Sheet: Spread the potatoes in a single layer on a large baking sheet or a stoneware pan. Avoid crowding so steam won’t prevent browning.
- Roast: Bake for about 25 minutes. Scrape and flip the potatoes so the bottoms that have crisped get exposed; bake an additional 5 minutes or until they are golden and tender when pierced with a fork.
- Serve: Serve hot, straight from the oven. Taste and adjust salt if needed.
Helpful Tips for Best Results
- Best Potato Types: Yukon Golds, red potatoes, and russets all work well. Yukon Golds are creamy, while russets get extra fluffy inside.
- Pan and Spacing Matter: Use a dark, heavy baking sheet or stoneware for better browning. Give the potatoes room—crowding prevents crisping.
- Parchment Note: Parchment makes cleanup easy, but for the crispiest edges skip it and roast directly on the pan.
- Season Freely: Swap or add spices—garlic powder, onion powder, thyme, or smoked paprika are great options.
Substitutions & Variations
- Swap Potatoes: Try sweet potatoes, baby potatoes, or fingerlings for a different texture and flavor.
- Seasoning Ideas:
- Garlic powder, onion powder, and thyme for a classic roast.
- Cajun or Creole seasoning for a spicy kick.
- Grated Parmesan and Italian herbs for a cheesy finish.
- Citrus-Free: Omit lemon and Dijon for a traditional roasted potato taste.
Kitchen Notes & Timing
Oven temperatures and pan materials vary, so start checking the potatoes around 15 minutes to gauge browning. Flip when the bottoms look nicely crisp. They’re done when a fork slides in easily and the exterior is golden.
