Ingredients
- 8 ounces noodles (spaghetti works best; you can also use thicker chow mein or hakka noodles)
- 1/4 teaspoon salt (adjust to taste)
- 1/4 teaspoon black pepper (adjust to taste)
- Sesame seeds (for garnish, if desired)
- 2 cups vegetable broth (or water)
- 2 teaspoons sesame oil
- 1 teaspoon ginger paste
- 1 teaspoon minced garlic
- 3 tablespoons soy sauce
- 1 tablespoon vinegar (rice vinegar recommended)
- 1-2 teaspoons red chili paste (adjust to taste; sambal oelek suggested)
- 1 teaspoon brown sugar
- 1/2 cup cabbage (thinly sliced)
- 1 carrot (peeled and sliced into matchsticks)
- 1/2 cup bell pepper (thinly sliced)
- 1/4 cup scallion or green onion (white and green parts divided)
- 1/2 cup broccoli (cut into very small florets)
Instructions
- Step 1: In a bowl, whisk together all the sauce ingredients—sesame oil, ginger paste, garlic, soy sauce, vinegar, red chili paste, and brown sugar—until well combined. Taste and adjust seasoning if needed.
- Step 2: Break the spaghetti noodles in half and add them to the Instant Pot.
- Step 3: Pour the prepared sauce over the noodles. Layer the cabbage, carrot, bell pepper, and the white part of the scallions on top of the sauce, leaving out the broccoli for now.
- Step 4: Seal the Instant Pot lid and set it to manual high pressure for 4 minutes.
- Step 5: When the cooking is done, perform a quick pressure release to safely open the lid.
- Step 6: Add the small broccoli florets and the green parts of the scallions, then stir the noodles gently with tongs to break up any clumps. Season with salt and black pepper to taste. Close the lid without sealing and let it sit for 5 minutes to steam the broccoli.
- Step 7: Open the lid, sprinkle sesame seeds and additional green onions on top if desired, then serve warm.
Tips & Variations
- For a protein boost, add tofu, cooked chicken, or shrimp before sealing the Instant Pot.
- Use gluten-free tamari instead of soy sauce for a gluten-sensitive option.
- Adjust the red chili paste to control the heat level—reduce or omit for a milder flavor.
- If you prefer softer vegetables, chop them smaller or increase the steaming time after cooking.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a microwave or on the stovetop with a splash of water or broth to keep the noodles moist. Avoid overcooking when reheating to maintain the veggies’ texture.

FAQs
Can I use other types of noodles for this recipe?
Yes, you can substitute spaghetti with chow mein, rice noodles, or even lo mein noodles. Just adjust the cooking time as needed, especially for thinner or more delicate noodles.
Is it necessary to steam the broccoli separately after pressure cooking?
Yes, adding the broccoli after the main cooking step and letting it steam with the lid closed prevents it from overcooking and becoming mushy. This keeps the broccoli tender-crisp and fresh-tasting.

Description
A quick and flavorful Instant Pot Vegetable Lo Mein recipe featuring tender noodles and a medley of fresh vegetables tossed in a savory, slightly spicy sauce. Perfect for a weeknight dinner, this dish combines the ease of pressure cooking with vibrant Asian-inspired flavors.
Ingredients
Noodles and Broth
- 8 ounces Noodles (Spaghetti works best; thicker chow mein or hakka noodles can also be used)
- 2 cups Vegetable Broth (or water)
Sauce
- 1/4 teaspoon Salt (adjust to taste)
- 1/4 teaspoon Black Pepper (adjust to taste)
- 2 teaspoon Sesame oil
- 1 teaspoon Ginger paste
- 1 teaspoon Garlic (minced)
- 3 tablespoon Soy Sauce
- 1 tablespoon Vinegar (rice vinegar recommended)
- 1–2 teaspoon Red chili paste (adjust to taste, sambal oelek used)
- 1 teaspoon Brown sugar
Vegetables
- 1/2 cup Cabbage (thinly sliced)
- 1 Carrot (peeled and sliced into matchsticks)
- 1/2 cup Bell Pepper (thinly sliced)
- 1/4 cup Scallion or Green onion (white and green parts separated)
- 1/2 cup Broccoli (cut into very small florets)
Garnish
- Sesame seeds (for garnish, optional)
- Green onion tops (from the scallions)
Instructions
- Prepare the Sauce: In a bowl, combine all the sauce ingredients including salt, black pepper, sesame oil, ginger paste, minced garlic, soy sauce, vinegar, red chili paste, and brown sugar. Whisk the mixture until evenly combined and taste to adjust seasoning as needed.
- Add Noodles to Instant Pot: Break the spaghetti noodles in half and place them into the Instant Pot bowl in an even layer.
- Layer Sauce and Vegetables: Pour the prepared sauce evenly over the noodles. Then add the sliced cabbage, carrot matchsticks, bell pepper, and the white parts of the scallions on top of the noodles and sauce. Reserve broccoli and green onion tops for later.
- Pressure Cook: Seal the Instant Pot lid and set it to manual/high pressure for 4 minutes. This cooks the noodles and softens the vegetables.
- Quick Release Pressure: When cooking is complete, perform a quick pressure release to stop the cooking process.
- Add Broccoli and Stir: Open the lid and add the small broccoli florets. Use tongs to stir and separate the noodles, breaking up any clumps. Season with additional salt and black pepper if desired.
- Steam Broccoli: Close the lid without sealing and let the broccoli steam inside the pot for 5 minutes. Do not pressure cook this step; the residual heat will gently cook the broccoli to retain its crispness.
- Garnish and Serve: Open the lid, sprinkle the green parts of the scallions and sesame seeds over the dish, and serve warm.
Notes
- You can adjust the red chili paste according to your spice tolerance.
- Using spaghetti noodles works well, but feel free to substitute with chow mein or hakka noodles for a more authentic texture.
- The steaming step after pressure cooking ensures broccoli retains a slight crunch and bright color.
- For added protein, consider tossing in tofu or your choice of cooked meat after cooking.
- Make sure broccoli florets are cut small to cook evenly during the steaming step.
