How to Cook Frozen Diced Potatoes in the Oven?

Potatoes are a staple food that is used in many different dishes around the globe. Among all preparations, diced potatoes are one of the most versatile ingredients that can be used as a side dish or incorporated into casseroles and stews.

Frozen diced potatoes are a convenient and reliable time-saver for busy individuals who do not have enough time to cut, wash and peel fresh potatoes before cooking. While there are different methods to cook frozen diced potatoes, this article will focus on how to cook them in an oven.

Preparing Frozen Diced Potatoes for Oven Cooking

Before baking or roasting your frozen diced potatoes, they should be defrosted first. To defrost the frozen dice potato properly, follow these steps:

  • Remove the frozen diced potatoes from their packaging and transfer them into a colander.
  • Rinse with cold water while shaking the colander gently to separate any stuck-together pieces.
  • Place on a paper towel or cloth and pat dry.
  • Leave it on your countertop for 30 minutes until fully defrosted.

Once defrosted, excess moisture needs to be removed before cooking; otherwise, the outcome may become soggy rather than crispy.

To remove excess moisture, wrap the thawed potato dice in a clean kitchen towel, cheesecloth gauze or paper towel and press lightly to squeeze out any excess water remaining.

Choosing the Right Pan for Cooking Frozen Diced Potatoes

A proper pan is essential for successful outcomes when cooking frozen diced potatoes in an oven. Some examples of pans that can be used include:

  • Non-stick sheet: Ideal for crispier results because it doesn’t absorb moisture as much as some other materials like glassware.
  • Glass container: Good option if you want to monitor your bake closely through transparency (but lengthen your cook time by several minutes compared with other pans).
  • Cast iron skillet: Perfect for restaurant-style, brown and crispy potato dice.

The pan you choose must be large enough to ensure that your potatoes cook evenly. Do not overcrowd the pan – ensure there’s enough space between every potato dice.

Seasoning and Spicing up Your Frozen Diced Potatoes

Seasoning your frozen diced potatoes before baking is essential for improved flavor. Adding a variety of spices and flavorings can add deliciousness and variety to any recipe. Here are five common seasonings people use for their diced potatoes:

  1. Salt: the most basic ingredient to enhance the natural taste of potatoes.
  2. Black pepper: perfect as a complementary spice with salt.
  3. Paprika: great for added smokiness, especially when used in small amounts.
  4. Garlic powder/granules: fantastic if you’re looking to add an extra surge of savory flavors.
  5. Rosemary: goes well with the earthy flavors of potatoes.

Mix these ingredients in a small bowl, then season your defrosted potato dice or include them in melted butter or cooking oil before spreading it over your potatoes.

Cooking Techniques

Baking Frozen Diced Potatoes

Here’s how you can bake frozen diced potatoes perfectly:

  1. Preheat your oven to 425°F (218°C) on convection mode or 450°F (232°C) on regular baking mode.
  2. Line your baking sheet with parchment paper or spray it lightly with cooking spray so that nothing will stick to it.
  3. Spread out the diced potato pieces across the tray in a single layer.
  4. Roast them for approximately 30 minutes, stirring halfway through.

Roasting Diced Potatoes from Frozen

If you’d instead like to get roasted frozen diced potatoes, follow these steps:

  1. Preheat oven to 400°F (204°C) on convection mode or 425°F (218°C) on regular baking mode.
  2. Prep a baking sheet lined with parchment paper or sprayed cooking spray.
  3. Spread out the thawed potatoes across the sheet in one layer.
  4. Add 1-2 tbsp of your favorite oil or butter to help them crisp and brown nicely
  5. Roast for roughly 25 minutes, stirring occasionally every 10 minutes or so.

Air-frying Frozen Diced Potatoes

Air-frying works well too – especially if you want more delicate but evenly cooked products:

  1. If available, preheat your air fryer to 400°F (204°C).
  2. In batches, place frozen diced potatoes into the air fryer basket until full but not overcrowded.
  3. Lightly spray cooking oil on top of them or use an oil-dipped brush to coat them evenly.
  4. Cook them for approximately ten minutes before flipping them over; then cook for another five to ten minutes until golden brown and crispy.

Storage Tips For Leftover Cooked Potatoes

Any leftover cooked diced potatoes will last up three days once properly stored in an airtight container and placed inside the fridge.

For reheating leftovers, use an oven or pan instead of microwave as it can make your potatoes either soggy or rubber-like texture. You can also repurpose diced potatoes in other recipes like stews, curries, soups or breakfast hash with eggs – the possibilities are countless!
