Gochujang buttered noodles are a quick, deeply savory weeknight pasta where Korean chili paste meets brown butter for a glossy, spicy, umami-packed sauce. The dish balances heat with richness and a touch of sweetness, coating every noodle in a silky, addictive glaze. It’s a flexible, one-pan meal that comes together in about 20 minutes, making it perfect for busy evenings when you want something satisfying without much fuss.
Ingredients
- 12 oz (340 g) dried spaghetti, fettuccine, or other long pasta
- 4 tbsp (56 g) unsalted butter, cut into pieces
- 2 tbsp (30 g) gochujang (Korean chili paste)
- 2 cloves garlic, minced
- 1 tbsp (15 ml) soy sauce
- 1 tsp (5 ml) toasted sesame oil
- 1 tbsp (15 g) brown sugar (optional, for extra sweetness)
- 1/2 cup (120 ml) pasta water, reserved from cooking
- 2 green onions, thinly sliced (for garnish)
- 1 tsp sesame seeds (for garnish)
- Salt, for pasta water
Instructions
- Bring a large pot of salted water to a boil (about 1 tbsp salt per 4 cups water). Add the pasta and cook according to package instructions until al dente. Before draining, reserve 1/2 cup (120 ml) of the pasta water. Drain the pasta and set aside.
- In a large skillet or sauté pan, melt the butter over medium heat. Add the minced garlic and cook, stirring frequently, for 1–2 minutes until fragrant but not browned.
- Add the gochujang, soy sauce, sesame oil, and brown sugar (if using) to the pan. Stir to combine, then cook for 1 minute, allowing the flavors to meld. The mixture will look thick and paste-like.
- Pour in the reserved pasta water, a little at a time, stirring constantly until the sauce becomes smooth and glossy. Simmer for 2–3 minutes to slightly reduce and thicken.
- Add the drained pasta to the skillet and toss well, ensuring every strand is coated in the sauce. If the sauce seems too thick, add a splash more pasta water or regular water to loosen it.
- Remove from heat and stir in half of the sliced green onions. Taste and adjust seasoning—add a pinch of salt if needed (remember the gochujang and soy sauce are already salty).
- Serve immediately, garnished with the remaining green onions and sesame seeds.
Tips
- Gochujang substitute: If you don’t have gochujang, mix 1 tbsp miso paste with 1 tsp chili flakes (like gochugaru or red pepper flakes) and a pinch of sugar. The flavor won’t be identical but will be close in heat and umami.
- Don’t overcook the garlic: Garlic burns quickly and turns bitter. Keep the heat medium and stir constantly when cooking it.
- Reserve extra pasta water: You might need more than 1/2 cup to get the right sauce consistency, especially if the pasta sits for a few minutes. Always reserve a full cup just in case.
- Adjust spice level: Gochujang varies in heat by brand. Start with 1.5 tbsp and add more to taste if you prefer a spicier dish.
Serving Suggestions
Serve these noodles as a main dish with a simple side of steamed greens (like bok choy or spinach) or a crisp cucumber salad. For protein, add grilled chicken, tofu, or shrimp. A soft-boiled egg on top also works beautifully, adding richness and extra texture.
Variations
- Add vegetables: Toss in sliced mushrooms, bell peppers, or zucchini when you add the garlic; cook until tender before adding the gochujang.
- Make it creamy: Stir in 2 tbsp of heavy cream or a dollop of sour cream at the end for a creamier, milder sauce.
- Use different noodles: This sauce works with udon, soba, or even rice noodles. Adjust cooking time accordingly.
- Add protein: Fold in shredded rotisserie chicken, cooked ground beef (ensure it reaches 160°F/71°C), or crispy tofu cubes.
- Vegan version: Use vegan butter or olive oil instead of butter, and skip the brown sugar if you prefer less sweetness.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. The noodles will absorb some sauce, so when reheating, add a splash of water or broth to loosen them. Reheat in a microwave for 1–2 minutes, stirring halfway, or in a skillet over medium heat for 3–5 minutes until hot. Reheat leftovers to an internal temperature of 165°F (74°C) for safety. Freezing is not recommended, as the texture of the pasta will become mushy.
Frequently Asked Questions
Can I use gluten-free pasta? Yes, any gluten-free pasta works. Cook it according to package instructions, and be careful not to overcook, as gluten-free pasta can become mushy quickly.
What is gochujang and where can I find it? Gochujang is a Korean fermented chili paste made from chili powder, glutinous rice, fermented soybeans, and salt. It’s savory, sweet, and spicy. You can find it in Asian grocery stores or online. If unavailable, use the substitute mentioned in the tips.
Is this dish very spicy? The heat level depends on the brand of gochujang and how much you use. Some brands are mild, others are quite hot. Start with less and add more to taste.
Can I make this ahead of time? It’s best served fresh, but you can prepare the sauce (without the pasta) up to 2 days ahead and keep it refrigerated. When ready to eat, cook fresh pasta and toss with the reheated sauce.
What can I use instead of butter? For a dairy-free version, use olive oil or vegan butter. The flavor will change slightly—olive oil gives a fruitier note, while vegan butter mimics the original more closely.
Why does my sauce look clumpy? Gochujang can clump if added to a hot pan without liquid. Make sure to whisk it with the pasta water or some of the melted butter before adding to the pan. Also, keep stirring to create a smooth emulsion.
