Now, I will guide you through the magical 10-minute Spicy Tuna and Potato Stew recipe in great detail.

Before You Start: Essential Ingredients and the Golden Ratio Sauce

The first step to successful cooking begins with proper preparation of ingredients. Since the cooking time for this dish is very short (around 10 minutes) and the process goes by in a flash, it is highly recommended to have all ingredients perfectly chopped and set up before turning on the stove. Check the list of ingredients below, prepared for 2 servings.

Main Ingredients Preparation

  • 1 Can of Tuna (approx. 100g-150g): You can use the oil from the tuna, but if you prefer a clean and light broth, it is better to slightly open the lid and squeeze out the oil, or drain it completely using a strainer. The unique savory flavor of the tuna drives the overall taste of the stew.
  • 2 Small Potatoes: Choose potatoes that are not too large. Fresh potatoes with firm flesh and no blemishes when peeled are best. Potatoes are the core ingredient of this dish, absorbing the boiling sauce to provide a fluffy and soft texture.
  • 1/2 Onion: Onions are a great vegetable that releases natural sweetness as they cook, reducing the need for artificial sugar. Although the crisp texture disappears, it adds deep flavor to the broth.
  • 1 Handful of Green Onions (Daepa): The unique fragrance and slight sharpness of green onions completely eliminate any potential fishiness from the tuna, leaving a very clean and refreshing aftertaste. It also serves as a visually excellent garnish.
  • 1 Pinch of Cheongyang (Spicy) Chili (Optional): If you enjoy spicy food that blows away stress, try finely chopping some spicy chilies. The added kick will complete the perfect side dish.

The Golden Ratio Sauce Ingredients

  • 1 Tablespoon Gochujang (Korean Red Chili Paste): The essential base for Korean seasoning, providing a deep, rich flavor and suitable consistency.
  • 1 Tablespoon Gochugaru (Korean Red Chili Flakes): Adds a vibrant, appetizing red color and a clean, spicy kick.
  • 1 Tablespoon Soy Sauce: Adds savory umami and perfectly balances the overall seasoning.
  • 1 Tablespoon Minced Garlic: An indispensable ingredient in Korean marinades that adds rich aroma and eliminates unpleasant odors.
  • 1 Tablespoon Sugar: Mildly neutralizes the spiciness and adds a beautiful gloss to the dish. You can reduce it to half a tablespoon if you prefer less sweetness.
  • 200ml Water: About one full paper cup. If you prefer a soupier style, you can add 50ml more water.
  • A Dash of Black Pepper: Sprinkled at the very last step to perfectly mask any remaining fishiness.

Foolproof 10-Minute Spicy Tuna and Potato Stew Instructions

Once all ingredients are ready, let's start cooking in earnest. The process is so intuitive and easy that even cooking novices can whip it up with their eyes closed.

1. Prep and Slice the Vegetables

First, slice the main vegetables, potatoes, and onions into bite-sized pieces. If potatoes are sliced too thinly, they can easily break apart from the heat during boiling, making the broth thick and messy. Conversely, if sliced too thickly, they will take too long to cook through, causing the tuna to become dry. Therefore, I recommend dicing them into 0.5cm to 1cm thick cubes or half-moons. Slice the onions into similar sizes and thicknesses to balance the cooking speed.

2. Layer the Vegetables in the Pot

Using an earthenware pot (ttukbaegi) or a cast-iron pot helps retain heat throughout the meal, making it even more enjoyable. Spread the sliced potatoes and onions evenly across the bottom of the prepared pot without leaving empty spaces. Layering firm vegetables at the bottom allows their natural juices to extract as they heat up, deepening the broth's flavor, and excellently prevents the tuna from directly touching the bottom and burning.

3. Mix the Magic Sauce

Now it's time to make the core sauce that determines the perfection of this dish. In a small bowl, mix 1 tablespoon of gochujang, 1 tablespoon of gochugaru, 1 tablespoon of soy sauce, 1 tablespoon of minced garlic, and 1 tablespoon of sugar evenly. Rather than measuring and adding them directly to the boiling pot, mixing them beforehand allows the chili flakes to absorb moisture and expand, resulting in a much richer red color and harmonizing the flavors.

4. Add the Tuna and Green Onions

Over the layered vegetables, gently place the drained tuna in one whole mound. Breaking the tuna too finely with a spoon or chopsticks can make the broth look messy, so maintaining large chunks is the secret to enhancing visual perfection. Generously top the tuna with a handful of chopped green onions to add fragrance. If you want a mouth-numbing spiciness, sprinkle the finely chopped spicy chilies at this stage.

5. Pour in the Sauce and Simmer

Carefully pour the specially mixed sauce into the center of the pot, and pour 200ml of water around the edges until the ingredients are slightly submerged. Initially, set the heat to high to encourage the broth to boil vigorously. Once the broth comes to a full boil, slightly cover the pot with a lid and reduce the heat to medium or medium-low. Simmer gently for about 5 to 7 minutes until the potatoes are completely fluffy and cooked through.

The most important precaution during this process is not to stir the ingredients too frequently with a spatula or spoon. As mentioned earlier, frequent friction will crush the tuna and break apart the well-cooked potatoes. However, if you prefer a rough style where you mix everything with the broth over rice later, you can gently stir occasionally to prevent sticking to the bottom without worrying about maintaining the shape.

6. Reduce the Broth and Serve

When the edges of the potatoes become slightly translucent and a chopstick pierces through smoothly without resistance, the dish is almost done. Once the spicy and sweet broth has fully penetrated the potatoes and tuna, and the volume of the broth has reduced to less than half of its original amount, turn off the stove. If you used an earthenware pot, the residual heat will continue cooking, allowing you to enjoy the appetizing bubbling sound with your eyes and ears when served on the table. Finally, add a dash of black pepper to your liking to complete the dish.

Expert Tips to Elevate Your Dish

While simply following the recipe will yield an excellent and delicious meal, adding a few subtle details will noticeably elevate the quality of the dish. I am specially sharing these hidden golden tips from culinary experts.

How to Keep Potatoes Intact

Immediately after slicing the potatoes, soak them in cold water for about 5 minutes to cleanly remove the surface starch. This process prevents the exterior of the potatoes from becoming sticky like paste or easily breaking apart during simmering, and it also prevents the broth from becoming thick and cloudy due to the starch. Never skip this simple yet powerful step if you want to preserve the fluffy, natural taste and texture of the potatoes. Also, if potatoes have been stored too long and have sprouted or parts of the skin have turned green from sunlight, they contain a natural toxin called 'solanine.' For your family's health, it is best to carve them out deeply with a knife or boldly discard them.

Balancing the Seasoning

Scientifically, molecules that provide sweetness are larger than salty molecules and are the last to penetrate ingredients. If you choose to add the seasonings separately directly into the pot instead of mixing them beforehand as introduced today, it is standard practice to add sweet seasonings like sugar or plum extract first to coat the exterior of the potatoes with a pleasant sweetness, and then add saltiness and spiciness with soy sauce and gochujang later. Furthermore, if you want an explosive umami flavor like in restaurants, try soaking a piece of dried kelp (kombu) in 200ml of water for a short time and use it as kelp stock instead of plain water. A deep and luxurious flavor rivaling chemical enhancers will come alive in the entire dish.

Smart Way to Use Tuna Oil

The original recipe recommends discarding the oil from the canned tuna for a clean and light taste. However, this tuna oil is not just ordinary cooking oil; it is like a delicious essence where the rich umami and nutrients of the tuna meat are concentrated. When layering the potatoes and onions at the bottom of the pot, drizzle a little tuna oil and sauté over low heat for about 1 minute. The savory aroma of the tuna will deeply penetrate the surface of the vegetables, making the overall broth taste much heavier and richer. If you choose this sautéing method, the broth might become slightly greasy, so slightly reducing the amount of soy sauce in the seasoning or adding a bit more spicy chili and black pepper to cut through the greasiness with spiciness is the perfect balance.

Perfect Side Dish Pairings

The completed Spicy Tuna and Potato Stew is a powerful main dish that can easily empty a bowl or two of rice with its presence alone. Generously scoop large, cooked potatoes and soft tuna chunks along with the thick broth over freshly cooked, steaming white rice, and mix vigorously with a spoon. As a finishing touch, if you fry an egg sunny-side up with a runny yolk and serve it on the side, the richness of the yolk will fantastically harmonize with the spicy and sweet seasoning, providing an ultimate taste experience.

Also, placing a spoonful of rice mixed with the stew onto crispy, unseasoned plain seaweed and wrapping it up is a delicacy among delicacies that I highly recommend. The plain seaweed softly neutralizes the intense spiciness while its unique, subtle ocean aroma adds depth to the heavy taste of the stew. If you have young children at home who cannot eat spicy food well yet, you can boldly omit the spicy chili flakes and gochujang from the sauce ratio, add a little more sugar or oligosaccharide to the soy sauce base, and simmer it into a salty and sweet teriyaki-style Soy Sauce Tuna and Potato Stew.
