Step-by-Step: Spicy Gochujang Beef Udon

Step 1: Prepare the noodles

Start by cooking the udon noodles according to package instructions. Usually, this means boiling them in salted water for 8–10 minutes until tender but still chewy. Once cooked, drain and rinse under cold water to stop cooking and set aside.

Step 2: Marinate the beef

In a bowl, combine the gochujang, soy sauce, and sesame oil. Add the thinly sliced beef sirloin and toss to coat thoroughly. Let it marinate for 10–15 minutes to absorb those bold flavors.

Step 3: Stir-fry the beef

Heat the vegetable oil in a large skillet or wok over medium-high heat. Add the marinated beef in a single layer and sear until browned and cooked through, about 3–4 minutes. Remove beef from skillet and set aside.

Step 4: Cook the vegetables

In the same skillet, add the sliced onion, minced garlic, bell pepper, broccoli florets, and julienned carrot. Stir-fry for 5–6 minutes, until the vegetables are tender-crisp and fragrant.

Step 5: Combine and finish

Return the cooked beef to the skillet with the vegetables. Add the cooked udon noodles and toss everything together. Adjust seasoning with salt and pepper to your preference. Stir-fry for another 2 minutes to heat through and allow the flavors to meld.

Step 6: Garnish and serve

Transfer your Spicy Gochujang Beef Udon to serving bowls. Sprinkle with sliced green onions and toasted sesame seeds for a pop of color and crunch. Serve immediately and enjoy!

Warm & Cool Weather Spins

• For cooler nights, add a splash of beef broth and extra gochujang to create a spicy noodle soup.
• On warmer days, serve the stir-fried beef and veggies over cold udon noodles tossed in a sesame-soy dressing for a refreshing cold noodle salad.
• Swap broccoli for snap peas or baby bok choy for varied green crunch.
• Add a soft-boiled egg or tofu cubes for extra protein and texture.

Errors to Dodge

• Don’t overcook the udon noodles; they should be tender but still have a chew to hold the sauce well.
• Avoid overcrowding the skillet when cooking beef—this causes steaming instead of searing.
• Be mindful with gochujang’s spice level; start with less if you prefer milder heat and adjust after tasting.
• Make sure to rinse cooked noodles under cold water to stop them from sticking and getting mushy.

Storage Pro Tips

This dish stores beautifully for meal prep or leftovers. Place cooled Spicy Gochujang Beef Udon in an airtight container and refrigerate for up to 3 days. When reheating, warm gently in a skillet over low heat, adding a splash of water or broth to loosen the sauce and keep noodles from drying out. Avoid microwaving without stirring to prevent uneven heating.

Helpful Q&A

Can I use another type of noodle?

Absolutely! While udon’s thick, chewy texture pairs perfectly with this dish, you can substitute with rice noodles, soba, or even spaghetti in a pinch. Just adjust cooking times accordingly.

Is there a substitute for gochujang?

If you don’t have gochujang on hand, a mix of chili paste and a bit of miso or tomato paste can mimic the sweet-spicy-salty profile. However, authentic gochujang really shines in this recipe.

Can I make this recipe vegetarian?

Yes! Swap the beef for firm tofu or tempeh, and increase the vegetables for a hearty vegetarian version. Make sure to use vegetarian-friendly soy sauce.

How spicy is this dish?

The heat level is moderate thanks to gochujang’s balanced spicy and sweet flavor. You can easily adjust by adding more or less gochujang or balancing with a touch of honey or sugar.
