Spicy Pork Udon Noodle Stir Fry

Udon noodle stir fries are a favourite fast and easy meal around here. I love the heartiness of these fat noodles! This 20 Minute Spicy Pork Udon Stir Fry, combines quick marinated pork with vegetables, udon noodles and a spicy sauce. Don’t worry though if you aren’t a spice lover. You can easily control the heat in this one!

This udon stir fry is the 2nd of three recipes I’m sharing this week that use “Fast Fry” boneless pork loin cutlets. Check out my Pork Tonkatsu Bowl recipe or my Pork Cordon Bleu recipe.

Ingredients and substitutions

A few notes about the key ingredients …

Pork – I used the thin “fast fry” pork loin chops (boneless), that I just cut into strips. You could also use a pork tenderloin, sliced and cut into strips.

Udon – You can start with fresh, frozen or shelf-stable, vacuum-sealed udon noodles. Shelf-stable udon does not need to be cooked ahead. They can go straight into the wok! For fresh, frozen or dried udon noodles, cook according to the package directions.

Recipe tips!

  • The heat in this udon stir fry comes from the Sambal Oelek. Using the 2 tsp will give you a nice kick. Add more if you’re a spice lover and of course, less if you’re not :) Sambal Oelek is more powerful in the heat department than Asian Chili Garlic Sauce. If you are using that option, you may need a bit more.
  • You could easily substitute boneless chicken (thighs or breast), for the pork in this stir fry. Or leave out the meat altogether for a vegetarian version.
  • As noted in the recipe instructions, as we are using the same sauce as a marinade (with the raw pork) and as a sauce in the stir fry, you’ll want to be sure to boil the finished sauce for several minutes, to ensure any meat juices are cooked.

Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes
Yield: 3 servings

Ingredients

Sauce:

  • 2 teaspoons Sambal Oelek, or Asian Chili Garlic Sauce
  • 1 Tablespoon + 1 teaspoon rice wine vinegar, seasoned or unseasoned
  • 1/2 cup soy sauce, low sodium recommended
  • 2 teaspoons sesame oil
  • 1/4 cup brown sugar
  • 3 cloves garlic, minced
  • 1 teaspoon fresh ginger, minced or ginger paste

Stir Fry:

  • 4-5 thin, boneless "fast fry" pork loin cutlets, or sliced and chopped pork tenderloin
  • 1 Tablespoon cooking oil
  • 1/2 medium onion, sliced
  • 1 medium carrot, peeled and cut into matchsticks
  • 1 medium red pepper, core and seeds removed and cut into matchsticks
  • 1/2 cup green onion, sliced diagonally (green part only)
  • 3 cups baby spinach
  • 15 oz fresh, frozen or vacuum-sealed udon noodles

For garnish:

  • Additional sliced green onion
  • 2-3 Tablespoons chopped peanuts

Instructions
 

  • In a medium bowl, stir together the Sauce ingredients. Set aside.
  • Trim any bit of fat off the then pork loin cutlets, then slice against the grain (width-wise) into bite-sized strips. Place into sauce and set aside to marinade a bit while you prepare your vegetables.
  • Prepare your vegetables by cutting your carrots and red pepper into matchsticks. Slice up the onion and green onion and have the baby spinach at hand. Keep separate vegetables separate, as they will be added at different times.
  • Heat a Tbsp of oil in a wok or skillet over medium-high heat (or a touch higher even) until hot. Using a slotted spoon (or strainer) remove the pork pieces from the marinade to the hot wok. (leaving the marinade in the bowl or reserving marinade). Cook pork, stirring, until cooked through. Remove to a bowl.
  • Add carrots to wok and cook, stirring, for about 2 minutes (I sometimes like to add a tablespoon of water here, to help the carrots cook more quickly and thoroughly). Add red pepper and cooking onion and cook a further minute or so, or until tender crisp. Add the green onion and cook, stirring, for another 30 seconds or so. Return pork to the wok.
  • Pour reserved marinade into wok and bring to a boil. Allow to boil for a minute or two. *Note: As we used the marinade earlier with raw meat, it is important that the sauce boil for several minutes, so don’t skip that part. Add udon to skillet and cook, tossing until udon is hot and well coated with sauce, 2-3 minutes.
  • Remove wok from heat and scatter baby spinach overtop. Allow to sit for 30-45 seconds, then toss the spinach into the stir fry, where it will wilt slightly from the heat of the stir fry.
  • Serve warm, garnished with chopped peanuts and additional sliced green onion.
