Chicken Lo Mein Instant Pot Recipe: Weeknight Takeout in 20 Minutes

This Instant Pot version brings authentic takeout flavor to your kitchen in a fraction of the time. The pressure cooker transforms chewy noodles and tender chicken into a dish that rivals your favorite restaurant.

The secret lies in the precise layering of ingredients and a 20-minute cook time that infuses every bite with savory depth. I’ve perfected the timing to ensure the noodles absorb just enough of the rich soy-garlic sauce without turning mushy.

What you’ll get is a weeknight solution that’s faster than delivery and packed with more vegetables. The chicken stays juicy, the noodles springy, and the sauce clings to every strand.

No special skills required—just follow the steps for a meal that feels like a treat but comes together effortlessly.

Ingredients for Chicken Lo Mein Instant Pot

Fresh veggies, tender chicken, and chewy noodles ready for your Instant Pot.

The chicken stays juicy if you slice it thin and uniformly. Costco has great boneless, skinless breasts in bulk, but any grocery store brand works fine. For the noodles, fresh lo mein from the refrigerated section at an Asian market is ideal (the texture is perfect), but dry egg noodles from the regular pasta aisle are a solid backup. Look for low-sodium soy sauce—it lets you control the saltiness better.

No dark soy sauce? Regular soy sauce plus a splash of molasses gets you close. Short on fresh ginger? Ground ginger at half the amount works in a pinch. The carrots can be pre-shredded (saves time), but whole carrots julienned yourself have better texture. If you’re out of chicken broth, water plus a bouillon cube does the trick. For extra veggie power, toss in some snap peas or mushrooms.

This keeps beautifully in the fridge for 4-5 days—the noodles actually soak up more flavor. Freeze for up to 3 months (without the veggies if you want them crisp). Reheat with a splash of water to loosen the sauce. I always make extra for lunches—tastes even better the next day.

Step-by-Step Instructions for Chicken Lo Mein

Here’s the method. Straightforward, tested, works every time.

Step 1: Sear the Chicken and Aromatics

Set your Instant Pot to Sauté mode and add the 2 tbsp vegetable oil. When it shimmers, add the 1 lb boneless skinless chicken breast in a single layer. Let it cook undisturbed for 2-3 minutes until it develops a light golden crust.

Add the 4 cloves garlic cloves and 1 tbsp fresh ginger, stirring constantly for 30 seconds until fragrant. This builds the flavor base that makes this dish taste like takeout. Don’t let the garlic burn—it turns bitter quickly.

Step 2: Add Vegetables and Deglaze

Toss in the 2 whole carrots, 1 whole red bell pepper, and the white parts of the 4 whole green onions. Stir-fry for 2 minutes until the vegetables begin to soften slightly but still retain their bright color.

Pour in the 0.5 cup soy sauce, 1 tbsp dark soy sauce, 2 tbsp brown sugar, and 1 cup chicken broth. Use a wooden spoon to scrape up any browned bits from the bottom of the pot—this adds depth to the sauce and prevents burning.

Step 3: Pressure Cook the Noodles and Chicken

Add the 8 oz lo mein noodles to the pot, gently pressing them down to submerge in the liquid. Secure the lid, set the valve to Sealing, and cook on High Pressure for 3 minutes. The noodles will absorb the flavors as they cook.

While the Instant Pot comes to pressure, mix the 1 tbsp cornstarch with 2 tbsp water to create a slurry. Once the cooking time is complete, quick-release the pressure carefully. The noodles should be tender and the chicken fully cooked through.

Step 4: Thicken the Sauce and Finish

Set the Instant Pot back to Sauté mode. Stir the cornstarch slurry into the noodle mixture and cook for 1-2 minutes until the sauce thickens to a glossy, clingy consistency that coats the noodles. The sauce should look slightly syrupy rather than watery.

Turn off the heat and stir in the 1 tbsp sesame oil and the green parts of the green onions. Taste and adjust seasoning with the 0.5 tsp salt if needed. The sesame oil adds a nutty aroma that ties everything together.

Troubleshooting Perfect Results

Noodles Too Mushy

If your noodles turned to mush, you likely overcooked them. Stick to exactly 3 minutes on High Pressure—this dish cooks fast! Also, ensure the noodles are fully submerged in liquid before sealing the lid. 💡

Sauce Too Thin

For a thicker sauce, make sure your cornstarch slurry is mixed well with 2 tbsp cold water. Stir it in during the final Sauté phase and cook for the full 1-2 minutes to activate the thickening power.

Chicken Overcooked

Slice your chicken into uniform, thin pieces (about ¼-inch thick). This ensures even cooking during the 3-minute pressure cycle. Thicker pieces can turn dry and rubbery.

Burn Notice

If you see the Burn error, immediately release the pressure and check the bottom. Deglaze thoroughly with ½ cup chicken broth after sautéing, scraping up all browned bits to prevent sticking.

Bland Flavor

Boost flavor by using low-sodium soy sauce and adjusting salt at the end. Don’t skip the 1 tbsp dark soy sauce—it adds depth. Taste before serving and add more brown sugar if needed. ✨

Vegetables Too Crunchy

For softer veggies, add them earlier in the Sauté step and cook for an extra 1-2 minutes. If you prefer crunch, add them right before pressure cooking to retain texture.
