For the Lo Mein

  • 8 oz of lo mein noodles or any other Asian-style noodles of your choice
  • 1 block (14 oz) of extra-firm tofu, cubed and pressed
  • 1 red bell pepper, thinly sliced
  • 1 yellow bell pepper, thinly sliced
  • 1 carrot, julienned or thinly sliced
  • 1 cup of broccoli florets
  • 1 cup of snow peas, trimmed
  • 1/2 cup of sliced mushrooms (any variety)
  • 1/2 cup of sliced green onions
  • 2 cloves of garlic, minced
  • 1 tablespoon of vegetable oil (for sautéing tofu)
  • Sesame seeds and additional sliced green onions for garnish (optional)

For the Lo Mein Sauce

  • 1/4 cup of soy sauce (or tamari for a gluten-free option)
  • 2 tablespoons of hoisin sauce
  • 2 tablespoons of rice vinegar
  • 1 tablespoon of brown sugar
  • 1 teaspoon of sesame oil
  • 1/2 teaspoon of ground ginger
  • 1/2 teaspoon of crushed red pepper flakes (adjust to taste)
  • 1/2 cup of vegetable broth
  • 2 tablespoons of cornstarch

Steps to Make

Step 1

  • Cube the extra-firm tofu and press it to remove excess moisture. You can use a tofu press or wrap the tofu in paper towels and place a heavy object on top for about 20-30 minutes.
  • After pressing, cut the tofu into bite-sized cubes.

Step 2

  • In a skillet, heat the vegetable oil over medium-high heat.
  • Add the tofu cubes and sauté until they turn golden brown and crispy on all sides. This should take about 5-7 minutes.

Step 3

  • In a bowl, whisk together the soy sauce, hoisin sauce, rice vinegar, brown sugar, sesame oil, ground ginger, crushed red pepper flakes, vegetable broth, and cornstarch until well combined.

Step 4

  • Place the sautéed tofu, red bell pepper, yellow bell pepper, carrot, broccoli florets, snow peas, sliced mushrooms, sliced green onions, and minced garlic in your slow cooker.
  • Pour the prepared Lo Mein sauce over the ingredients in the slow cooker.

Step 5

  • Cover your slow cooker and set it to low heat.
  • Allow the Tofu Lo Mein to cook for 2-3 hours, giving the flavors time to meld together and the vegetables to become tender.

Step 6

  • Cook the lo mein noodles according to the package instructions until they are al dente. Drain and set aside.

Step 7

  • About 15-20 minutes before serving, add the cooked lo mein noodles to the slow cooker and gently stir to combine with the tofu and vegetable mixture.

Step 8

  • Once the Tofu Lo Mein is hot and well combined, it’s ready to serve.
  • Garnish with sesame seeds and additional sliced green onions if desired.


Slow-Cooker Tofu Lo Mein is a flavorful and convenient way to enjoy the classic Asian dish with a meatless twist.

The combination of sautéed tofu, vibrant vegetables, and a savory sauce creates a delightful meal that’s both satisfying and convenient to prepare. Using a slow cooker simplifies the cooking process, making it ideal for busy days.
