Easy 20-min Soy Egg Udon Stir Fry Ingredients

This Easy 20-min Soy Egg Udon Stir Fry comes together with a handful of simple ingredients, many of which you might already have in your pantry. The magic is in how they come together so quickly.

For the Soy Eggs (Ajitsuke Tamago):

• 4 large eggs
• 1/4 cup soy sauce (or tamari for gluten-free)
• 1/4 cup water
• 1 tablespoon mirin (or 1 tsp sugar mixed with 1 tbsp water)
• 1 teaspoon sesame oil

For the Udon Stir Fry:

• 2 packs (approx. 14 oz) pre-cooked udon noodles
• 1 tablespoon vegetable oil
• 2 cloves garlic, minced
• 1-inch piece ginger, grated
• 1 cup sliced shiitake mushrooms
• 1 bell pepper, thinly sliced
• 2 cups chopped bok choy or cabbage
• 2 green onions, sliced (white and green parts separated)

For the Stir Fry Sauce:

• 3 tablespoons soy sauce
• 1 tablespoon oyster sauce (or vegetarian oyster sauce)
• 1 tablespoon rice vinegar
• 1 teaspoon sesame oil
• 1 teaspoon sugar or honey
• (Optional) 1 teaspoon chili garlic sauce or sriracha for heat

Smart Swaps:

• Noodles: Can’t find udon? Thick ramen noodles or even spaghetti work in a pinch.
• Protein: Add cooked chicken, shrimp, or tofu for a more substantial meal.
• Veggies: This is a great clean-out-the-fridge recipe. Carrots, snap peas, or broccoli would all be fantastic additions.

Step-by-Step Instructions for Your Soy Egg Udon

The process is straightforward, but a few key steps make all the difference in building deep, savory flavor.

1. Prepare the Soy Eggs: Gently lower the eggs into a pot of boiling water and cook for 6-7 minutes for a perfectly jammy, soft-boiled yolk. Immediately transfer them to an ice bath to stop the cooking. Once cool, carefully peel them. In a small bowl or container, mix the soy sauce, water, mirin, and sesame oil. Add the peeled eggs, ensuring they are submerged. Let them marinate while you cook the stir fry.
2. Loosen the Noodles: If using pre-cooked udon from packages, run the noodles under warm water to separate them. This prevents them from sticking together in the wok.
3. Stir Fry the Aromatics & Veggies: Heat the vegetable oil in a large wok or skillet over medium-high heat. Add the garlic, ginger, and the white parts of the green onions. Stir for 30 seconds until fragrant. Add the mushrooms and bell pepper, and stir-fry for 2-3 minutes until they begin to soften.
4. Sauce and Combine: Push the veggies to one side. Pour the stir fry sauce ingredients directly into the hot pan. Let it bubble and sizzle for just a moment to wake up the flavors. Then, add the bok choy and the udon noodles. Using tongs, toss everything together until the noodles are evenly coated in the sauce and the bok choy has wilted, about 2-3 minutes.
5. Final Touches: Turn off the heat and stir in the green parts of the green onions and the remaining teaspoon of sesame oil for a final flavor boost.

A Note on Nutrition

This dish is a wonderfully balanced meal. A single serving provides a good source of protein from the egg, complex carbohydrates from the udon for energy, and a variety of vitamins from the fresh vegetables. The soy-based sauce adds a savory umami depth without being overly heavy.

Equipment You’ll Need

You don’t need any fancy gadgets for this recipe. A large wok or a big, sturdy skillet is your best friend here, giving you plenty of room to toss the noodles. You’ll also need a medium pot for the eggs, a small bowl for the marinade, and a set of tongs for easy mixing.

Why You’ll Love This Easy Udon Stir Fry

• Speed Demon: It genuinely lives up to its 20-minute promise, making it a reliable go-to on your busiest nights.
• Customizable Canvas: Easily adapt the vegetables and protein based on what you have available.
• Comfort in a Bowl: The combination of chewy noodles, savory sauce, and a rich, runny soy egg is deeply satisfying.
• Minimal Cleanup: With only one main pan and a couple of bowls, you’re not left with a mountain of dishes.

Healthier Twists for Your Noodle Dinner

This recipe is already quite balanced, but you can easily tweak it to meet specific dietary goals.

• Lower Carb: Use shirataki noodles or zucchini noodles (“zoodles”) in place of udon. You may need to reduce the sauce slightly as these noodles hold less liquid.
• Reduce Sodium: Use low-sodium soy sauce and reduce the amount by half, tasting as you go.
• Add More Protein: Stir in edamame or a extra sliced soy egg right into the noodles.

Serving Your Soy Egg Udon Stir Fry

Divide the stir fry between two bowls. Take a soy egg from the marinade, slice it in half, and place it right on top of the steaming noodles. The golden, runny yolk will mingle with the sauce, creating a luxurious coating. For a bit of crunch and freshness, garnish with sesame seeds and extra sliced green onion.

Common Mistakes to Avoid with Your Stir Fry

• Overcooking the Eggs: A hard-boiled yolk won’t create that saucy, rich texture. Stick to the 6-7 minute boil and immediate ice bath.
• Crowding the Pan: If your skillet is too small, the vegetables will steam instead of fry. Use the largest pan you have for the best results.
• Skipping the Noodle Rinse: Pre-cooked udon noodles are often dusted with starch to prevent sticking. Not rinsing them can lead to a gummy, clumpy stir fry.
• Adding Cold Sauce: Let the sauce hit the hot pan for a moment before adding the noodles. This quick caramelization builds a more complex flavor base.

Storing Your Leftover Udon Stir Fry

This dish is best enjoyed immediately, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days. The noodles will soften considerably upon reheating. To reheat, add a splash of water or broth to a skillet and warm gently over medium heat, stirring frequently. I do not recommend freezing this dish, as the texture of the noodles and vegetables will suffer.

The soy eggs can be stored in their marinade in the fridge for up to 3 days. They become more flavorful the longer they sit!
