Ingredients

• 1 lb baby potatoes or small Yukon Gold potatoes (about 12-15 potatoes, each about 1.5 inches wide)
• 1 tablespoon olive oil
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/2 cup kimchi, drained and roughly chopped (use more for extra spicy)
• 2 large eggs
• 1/4 cup shredded mozzarella cheese (optional, for melty goodness)
• 1 green onion, thinly sliced (for garnish)
• 1 teaspoon sesame seeds (optional, for garnish)
• Sriracha or gochujang sauce for drizzling (optional)

Optional Substitutions

• Use sweet potatoes or red potatoes instead of baby potatoes. Sweet potatoes add natural sweetness; red potatoes hold shape well.
• Swap the eggs with egg whites or tofu scramble for a lower-cholesterol or vegan version.
• Replace mozzarella with cheddar, feta, or skip the cheese for a dairy-free option. Cheddar melts sharp and rich; feta adds tangy saltiness.
• Use mild kimchi if you prefer less heat, or try cabbage kimchi, radish kimchi, or even sauerkraut for a different tang.
• Add cooked bacon, sausage, or leftover ham for extra protein and savoriness. Just chop and sprinkle on top.
• Swap olive oil with avocado oil for a higher smoke point and neutral flavor.
• Try a sprinkle of everything bagel seasoning for a fun twist — it adds crunch and flavor.

Instructions

1. Prep the potatoes: Scrub the potatoes clean but leave the skin on for extra texture. Place them in a microwave-safe bowl with 2 tablespoons of water. Microwave on high for 4-5 minutes until fork-tender. (Alternatively, boil them in salted water for 10-12 minutes.) Drain and let cool slightly.
2. Smash the potatoes: Place each potato on a cutting board and use the bottom of a glass or a potato masher to gently smash it until it's about 1/2-inch thick. Don't worry if some break apart — that means more crispy edges.
3. Season and air fry: In a bowl, toss the smashed potatoes with olive oil, salt, and pepper. Arrange them in a single layer in the air fryer basket. Cook at 400°F (200°C) for 10 minutes.
4. Add kimchi and eggs: After 10 minutes, flip the potatoes. Scatter the chopped kimchi over the potatoes, making sure some pieces nestle between them. Crack the eggs carefully over the potatoes and kimchi. If using cheese, sprinkle it on top.
5. Finish cooking: Return the basket to the air fryer and cook at 370°F (185°C) for another 6-8 minutes for runny yolks, or 9-10 minutes for firmer eggs. The eggs should be set to your preference.
6. Garnish and serve: Carefully remove the egg smash from the air fryer (use a spatula to release any stuck bits). Sprinkle with sliced green onion and sesame seeds. Add a drizzle of sriracha or gochujang if desired. Serve immediately.

Pro Tips

• Par-cook the potatoes until just tender, not mushy. Overcooked potatoes will fall apart when smashed. Aim for a fork that meets slight resistance.
• Don't overcrowd the air fryer basket. Leave a little space between potato pieces so air circulates and they get crispy. Cook in batches if needed.
• Flip halfway through the initial potato cooking to ensure even browning on both sides.
• For extra crispy smashed potatoes, let the par-cooked potatoes dry out for a few minutes before smashing — less steam means more crunch.
• Use a non-stick air fryer basket or line with perforated parchment paper to prevent the eggs from sticking. The cheese can also help create a release layer.
• Adjust cooking time based on egg doneness. Start checking at 6 minutes for soft yolks. Remember the eggs continue to cook slightly after removal.
• Drain the kimchi well so excess liquid doesn't make the potatoes soggy. Pat dry with a paper towel if needed.
• Serve immediately for the best texture — the potatoes stay crispy for only about 10-15 minutes after cooking.

Variations and Substitutions

• Kimchi Potato Egg Bowl: Don't feel like smashing? Simply cube the potatoes and air fry them, then top with kimchi and fried eggs for a deconstructed version.
• Loaded Kimchi Potato Smash: After cooking, top with sour cream, avocado slices, and extra kimchi for a loaded-baked-potato vibe.
• Kimchi Potato Egg Quesadilla: Use the cooked potato and egg mixture as a filling for a crispy flour tortilla quesadilla with cheese.
• Breakfast Tacos: Spoon the hot potatoes and eggs into warm corn tortillas, drizzle with crema (or Greek yogurt) and hot sauce.
• Spicy Kimchi Potato Hash: Increase the spice by adding a teaspoon of gochugaru (Korean chili flakes) to the oil before tossing potatoes.
• Vegan Kimchi Potato Smash: Replace eggs with a tofu scramble or chickpea flour scramble, and use dairy-free cheese or avocado.
• Kimchi Potato Egg Grilled Cheese: Layer the smash between two slices of sourdough with extra cheese and grill until golden.

Storage and Reheating

Fridge

Store leftover kimchi potato egg smash in an airtight container in the refrigerator for up to 2 days. The potatoes will lose some crispiness but remain tasty.

Freezer

Freezing is not recommended for the assembled dish because the eggs and potatoes become watery when thawed. However, you can freeze the plain smashed potatoes (before adding kimchi and eggs) for up to 3 months. Reheat them directly in the air fryer from frozen, then add fresh kimchi and eggs.

Reheating

For best results, reheat leftovers in the air fryer at 350°F (175°C) for 3-5 minutes to revive the crispiness. Microwaving will make the potatoes soft and the eggs rubbery, so avoid that if possible. If you must microwave, use a low power setting and cover loosely.

FAQ

Can I make this recipe without an air fryer? Yes! Bake the smashed potatoes on a sheet pan in a 425°F (220°C) oven for 20-25 minutes, then add kimchi and eggs and bake another 5-8 minutes. You can also use a cast-iron skillet on the stovetop.

Do I have to microwave the potatoes first? Microwaving or boiling the potatoes before smashing ensures they cook through evenly and become tender. If you skip this step, the potatoes may not be fully cooked by the time the eggs are done.

Can I use a different type of potato? Yes, baby Yukon Gold, red potatoes, or even fingerlings work well. Avoid large baking potatoes unless you cut them into smaller chunks.

What if I don't like spicy food? Use mild kimchi (labeled “mild” or “white kimchi”) and reduce or omit the optional sriracha. The dish will still have tangy, savory flavor without the heat.

How can I make the eggs cook faster? If you prefer quicker egg cooking, crack the eggs after the potatoes have cooked for 12 minutes (instead of 10). The residual heat will help set the whites faster.

Can I add other vegetables? Absolutely! Add chopped bell peppers, mushrooms, or zucchini along with the kimchi. Just make sure they are cut small so they cook through.

Is this recipe gluten-free? Yes, all the ingredients listed are naturally gluten-free. Just double-check that your kimchi brand doesn't contain wheat-based soy sauce.

How do I prevent the eggs from sticking to the air fryer basket? Spray the basket well with cooking spray before adding the potatoes. You can also use a silicone liner or parchment paper with perforations (cut to fit).
