Eo Nam-seonsaeng's One-Pan Milk Butter Pasta

Ryu Soo-young's super-simple one-pan pasta recipe that took 'Fun-staurant' by storm. No need to boil pasta separately; everything cooks in one pan with milk, butter, and tuna sauce for a deep, savory flavor.

The 'One-Pan Milk Butter Pasta' introduced by Ryu Soo-young (Eo Nam-seonsaeng) on KBS2's 'Fun-staurant' is a game-changing recipe for busy home cooks and students. Traditional pasta requires boiling water in a large pot to cook noodles separately before making sauce in another pan. This one-pan magic reduces cleanup and slashes cooking time to around 15 minutes, offering restaurant-quality results with zero hassle. The scientific brilliance lies in natural starch emulsification. As the pasta cooks directly in the liquid, its starch binds with milk and butter, creating a silky, luxurious texture without heavy cream. The starch coats each noodle strand tightly, locking in rich, comforting flavors while saving leftover cream from going to waste. Chef Ryu's signature twist is the addition of 'tuna sauce' and freshly minced garlic. The garlic cuts through the rich dairy, while tuna sauce delivers an unexpected smoky umami kick. Perfect for quick weeknight dinners or cozy weekend treats, discover how to master this viral dish step-by-step!

👨‍🍳 Cooking Steps

1

In a deep pan or pot, combine 500ml water, 300ml milk, 20g butter, and 0.5t salt, and bring to a boil over high heat.

💡 Tip: Milk overflows easily, so watch carefully and adjust the heat as it starts to bubble up.
2

Once the liquid is boiling, spread and add 100g of spaghetti noodles.

💡 Tip: Stir the pasta immediately after adding so the strands do not stick to the bottom.
3

Reduce to medium heat and simmer for about 10 minutes, stirring occasionally, until the pasta absorbs the sauce.

💡 Tip: Stir frequently to prevent the starch and dairy mixture from scorching at the bottom.
4

When the liquid reduces significantly, add 1T of tuna sauce and 1T of minced garlic. Stir well and cook for 2 more minutes.

💡 Tip: Adding tuna sauce near the end preserves its rich aroma and maximizes the savory taste.
5

Once the sauce becomes thick and coats the pasta, turn off the heat, plate, and garnish with Parmesan cheese powder and freshly ground black pepper.

💡 Tip: Freshly cracked black pepper provides a punchy contrast to the creamy sauce.

🌟 Pro Chef Tips

  • • Cooking the pasta in one pan allows the starch from the pasta to naturally thicken the milk sauce into a velvety consistency.
  • • Tuna sauce is Chef Ryu's signature kick, adding a surprisingly deep, savory depth that pairs wonderfully with butter.
  • • Adding minced garlic near the very end keeps its aromatic garlic flavor fresh and pungent.

⚠️ Avoid Common Pitfalls

  • ❌ If the heat is too high, the liquid will evaporate before the pasta cooks. Keep it at a steady medium simmer.
  • ❌ Adding garlic too early might scorch it, turning the sauce bitter and losing its fresh aroma.
  • ❌ Failing to stir early on causes a milk skin to form, leading to noodles burning at the bottom.

🧂 Spice & Seasoning Adjustments

  • • Add chopped red chili flakes or fresh hot peppers if you prefer a spicy cream pasta variation.

🧊 Storage & Reheating

  • • One-pan pasta is best enjoyed immediately.
  • • If needed, store in an airtight container in the fridge for up to 1 day and reheat with a splash of milk.

❓ Frequently Asked Questions

Q. Can I use regular soy sauce instead of tuna sauce?

A. You can, but it won't have the unique smoky umami. For the best result, mix half a tablespoon of soup soy sauce and half a tablespoon of fish sauce.

Q. Does it really get creamy without heavy cream?

A. Yes! The starch released from the pasta naturally emulsifies with the milk and butter, creating a thick, creamy sauce without any heavy cream.

Q. What should I do if the pasta keeps sticking to the bottom?

A. Scrape and stir the bottom of the pan frequently with a spatula. If it sticks too fast, lower the heat slightly.

Q. Can I use soy milk or low-fat milk instead?

A. Low-fat milk yields a thinner taste due to lower fat content. Unsweetened soy milk works, though it adds a nutty soy note. Standard whole milk is recommended.

Q. How should I reheat leftover pasta?

A. Leftover pasta thickens as it cools. Add 2-3 tablespoons of milk or water and gently heat over low heat while stirring.
