Ingredients for Instant Pot Lo Mein

Simple staples transform into restaurant-quality lo mein with tender noodles and crisp vegetables.

The noodles are non-negotiable for texture—look for dried lo mein in the Asian aisle at Whole Foods or H Mart. Chicken breast stays juicy when sliced thin against the grain. For ginger and garlic, fresh is essential (the jarred stuff lacks punch). Carrots and bell peppers add crunch—julienne them uniformly so everything cooks at the same rate.

No lo mein noodles? Spaghetti or linguine work in a pinch, but reduce cooking time by a minute. Swap chicken for shrimp or tofu—adjust pressure time accordingly. Vegetarian? Vegetable broth and mushrooms add depth. Oyster sauce is traditional, but hoisin or extra soy sauce keeps it flavorful. Always taste before serving—balance the soy, sugar, and sesame to your preference.

Leftovers keep 4-5 days in the fridge, though noodles soften over time. Freeze without vegetables for up to 3 months. Reheat with a splash of water to loosen the sauce—microwave works, but stovetop revives the texture better.

Step-by-Step Instructions for Instant Pot Lo Mein

This method delivers authentic wok-fried flavor with minimal effort and maximum speed.

Step 1: Prepare and Sauté the Aromatics and Chicken

Set the Instant Pot to Sauté mode on Normal heat and add the 1 tbsp Vegetable Oil. Once hot, add the 1 lb Chicken Breast slices in a single layer. Cook undisturbed for 3-4 minutes until the edges turn opaque and begin to brown.

Remove the chicken and set aside. In the same pot, add the minced 4 cloves Garlic Cloves and grated 1 tbsp Fresh Ginger. Sauté for 30-45 seconds until fragrant, stirring constantly to prevent burning. This builds the flavor foundation for the dish.

Step 2: Cook the Vegetables and Deglaze

Add the julienned 2 whole Carrots and thinly sliced 1 whole Bell Pepper to the pot. Stir-fry for 2-3 minutes until the vegetables soften slightly but retain a crisp texture. The carrots should brighten in color and the bell pepper should begin to glisten.

Pour in ½ cup of the 1 cup Chicken Broth to deglaze the pot, scraping the bottom with a wooden spoon to release any browned bits. These fond bits are packed with flavor and will dissolve into the sauce, enhancing its depth.

Step 3: Pressure Cook the Noodles and Chicken

Add the 8 oz Dried Lo Mein Noodles, remaining ½ cup Chicken Broth, 0.33 cup Soy Sauce, 2 tbsp Oyster Sauce, 1 tbsp Brown Sugar, and the cooked chicken to the pot. Stir well to combine, ensuring the noodles are fully submerged 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 of the sauce as they cook, resulting in a perfectly seasoned dish. After cooking, allow for a 2-minute natural release before quick-releasing any remaining pressure.

Step 4: Finish with Cornstarch Slurry and Sesame Oil

In a small bowl, mix the 1 tbsp Cornstarch with 2 tbsp of water to create a slurry. Stir this into the Instant Pot and set it back to Sauté mode on Normal heat. Cook for 1-2 minutes, stirring constantly, until the sauce thickens to a glossy, velvety consistency.

Turn off the heat and stir in the 1 tbsp Sesame Oil. This adds a rich, nutty aroma that ties all the flavors together. Taste and adjust seasoning if needed, though the combination of soy and oyster sauce should provide a well-balanced savory profile.

Step 5: Garnish and Serve

Slice the 3 whole Green Onions, separating the white and green parts. Stir the white parts into the lo mein, then transfer the dish to a serving platter. Garnish with the green onion tops and sprinkle with 1 tsp Sesame Seeds for added texture and visual appeal.

Serve immediately while hot. The noodles should be tender but still slightly chewy, coated in a rich, umami-packed sauce with tender chicken and crisp vegetables. The sesame seeds will add a subtle crunch and toasty flavor to each bite.

Make-Ahead Tips for This instant pot lo mein

Prep Ahead Strategy

Chop all vegetables the night before—julienne 2 carrots and slice 1 bell pepper—and store in an airtight container with a damp paper towel to maintain crispness. This saves 10 minutes on cooking day. 💡

Protein Prep

Slice the 1 lb chicken breast into thin strips and marinate in 1 tbsp soy sauce and 1 tsp cornstarch for 30 minutes. This keeps the meat tender and ready for quick cooking. I do this while prepping veggies.

Sauce Mix

Combine ⅓ cup soy sauce, 2 tbsp oyster sauce, and 1 tbsp brown sugar in a jar the night before. Shake well before using—this ensures flavors meld beautifully. Store at room temperature.

Noodle Prep

Break 8 oz lo mein noodles in half so they fit better in the Instant Pot. No need to pre-soak—just add them dry to the pot with other ingredients. This prevents clumping and ensures even cooking.

Day-Of Assembly

When ready to cook, everything goes into the Instant Pot in stages: chicken first, then veggies, then noodles and sauce. The whole process takes under 30 minutes start to finish.

Storage Before Cooking

Keep prepped ingredients separate in the fridge. Chicken and sauce can stay together, but veggies should be in their own container. Use within 24 hours for best texture and flavor.
