Instant Pot Leek Mashed Potatoes

Mashed potatoes are a beloved side dish around the world. Their comforting nature and simple preparation have made them a staple across cultures for centuries. From creamy and smooth to chunky and rustic, mashed potatoes offer endless variations. Adding leeks to the classic recipe introduces a subtle sweetness and delicate onion flavor, elevating this humble dish.

Leeks belong to the same family as onions and garlic, but offer a milder, more refined taste profile. When cooked, they become incredibly tender and add a delicious depth to mashed potatoes.

The Instant Pot revolutionizes mashed potato making! This versatile kitchen appliance cuts down on both cooking time and cleanup. By pressure cooking the potatoes and leeks, you’ll achieve perfectly fluffy results in a fraction of the time compared to traditional stovetop methods. It’s a fantastic way to get a delicious, satisfying side dish on the table with minimal effort.

Recipe Details

Ingredients

• Potatoes (2 pounds): Yukon Gold potatoes are ideal for their creamy texture, but russets work well too.
• Leeks (1 large or 2 medium): Use the white and light green parts, thoroughly washed to remove any grit.
• Butter (4 tablespoons): Provides richness. For a dairy-free option, substitute with olive oil or a vegan butter alternative.
• Milk (1/2 cup): Warmed milk helps create a smoother consistency. For dairy-free, unsweetened plant-based milks (almond, oat, etc.) work well.
• Salt and pepper (to taste): Essential for seasoning.

Optional Additions

• Garlic (2-3 cloves, minced): Adds a savory note.
• Fresh herbs (thyme, chives, parsley): Choose your favorite for a flavor boost.
• Sour cream or Greek yogurt: Adds a delightful tanginess.
• Cheese (Parmesan, cheddar): A classic topping for those who enjoy it.

Preparation Steps

1. Prep the Potatoes:

   • Peel potatoes and cut them into roughly 1-inch cubes. Uniform pieces ensure even cooking.
   • For a rustic texture, you can leave the potato skins on.

2. Slice the Leeks:

   • Remove the root end and the tough, dark green parts of the leek.
   • Slice the remaining white and light green portions lengthwise in half, then into thin half-moon slices.
   • Rinse leeks thoroughly in a colander under cool water to remove any dirt or sand.

3. Assemble in the Instant Pot:

   • Place the potatoes and leeks into the Instant Pot’s inner pot.
   • Add enough water to just cover the vegetables. For most Instant Pots, this is about 1 cup of water.
   • Season generously with salt.

4. Pressure Cook:

   • Secure the Instant Pot lid and make sure the pressure valve is set to “Sealing.”
   • Select the “Manual” or “Pressure Cook” setting and cook on High pressure for 8 minutes.

5. Release Pressure (Choose One):

   • Natural Release: Allow the pressure to release naturally for 10 minutes. This gentler method is ideal for very creamy mashed potatoes.
   • Quick Release: Carefully turn the pressure valve to “Venting” to release the remaining pressure. Use caution as steam will be hot.

6. Drain and Mash:

• Once the pressure is fully released, carefully open the lid.
• Drain any excess cooking liquid.
• Add butter (or dairy-free substitute) and warmed milk.
• Use a potato masher, hand mixer, or large fork to mash until your desired consistency is reached.
• Season to taste with salt and pepper.

Tips:

• Avoid overfilling your Instant Pot. Keep ingredients below the maximum fill line.
• If you prefer firmer mashed potatoes, reduce the cook time by 1-2 minutes.
• For extra creamy results, warm the milk before adding it.
• Use a potato ricer for the smoothest, lump-free mashed potatoes.

Cooking Method

The Instant Pot makes cooking perfectly tender potatoes and leeks incredibly simple. Here’s the breakdown of the process:

1. Pressure Cooking: The high-pressure environment inside the Instant Pot cooks the potatoes and leeks much faster than traditional boiling. The trapped steam raises the temperature above water’s usual boiling point, leading to rapid softening of the vegetables.

2. Pressure Release: Two options exist for releasing the pressure after cooking:

   • Natural Release: This involves letting the Instant Pot sit undisturbed for about 10 minutes. The pressure slowly dissipates on its own. This is good for creamy, softer mashed potatoes.

   • Quick Release: This involves carefully turning the release valve to the “Venting” position. Hot steam will rapidly escape. Use caution and keep your hands clear. This method is better if you prefer mashed potatoes with a bit more texture.

3. Achieving Your Ideal Texture: The main factor controlling your mashed potatoes’ texture is the combination of cooking time and pressure release method.

• Creamy: Cook for the full 8 minutes and use a natural release.
• Slightly Chunky: Reduce the cook time to 6-7 minutes and use a natural release.
• Rustic: Cook for 6 minutes and do a quick release.

Additional Tips:

• Start with cold water in your Instant Pot. This helps the potatoes cook more evenly.
• For ultra-smooth potatoes, run them through a ricer after draining.
• Don’t over-mash, as this can make the potatoes gummy. Start gently and mash until you reach your desired consistency.

Cook’s Notes

• Doubling the Recipe: You can easily double this recipe. However, you may need to increase the cooking time by a couple of minutes to ensure the potatoes are fully cooked.
• Protect Your Instant Pot: For starchy foods like potatoes, use a trivet or steamer basket inside the inner pot. This prevents direct contact and lessens the chance of food sticking and potentially causing a “burn” message.
• Potato Variations: Experiment with different potato types! Red potatoes, sweet potatoes, and even a mix of varieties can add new flavor dimensions to your mashed potatoes.
• Spice It Up: If you like a little kick, add a pinch of red pepper flakes or cayenne pepper during the cooking process.
• Make-Ahead: Mashed potatoes can be made 1-2 days in advance and reheated. Keep them in an airtight container in the refrigerator.

Serving Suggestions

• Garnishes That Shine:

  • A pat of melted butter creates a classic pool of richness.
  • Freshly chopped chives or green onions add color and a mild onion flavor.
  • Chopped parsley offers a vibrant pop of green and freshness.
  • A sprinkle of crispy bacon bits for salty, savory goodness.
  • A dollop of sour cream or Greek yogurt adds tanginess.
  • Grated Parmesan or cheddar cheese adds a savory depth.

• Perfect Pairings: Instant Pot Leek Mashed Potatoes are incredibly versatile and pair beautifully with a wide range of dishes. Here are a few ideas:

  • Roast chicken or turkey
  • Pan-seared steaks or pork chops
  • Meatloaf or lentil loaf
  • Fried or baked fish
  • Steamed vegetables like broccoli, carrots, or green beans.
  • Serve alongside a fresh salad for a lighter meal

• Creative Presentation: Elevate your mashed potatoes with a simple swirl using the back of a spoon. Sprinkle with your favorite garnishes for a dish that’s as pleasing to the eye as it is to the palate.

Tip: Warm your serving plates for the ultimate comfort food experience!
