## Ingredients You’ll Need

Before we dive into the recipe, let’s gather all the necessary ingredients. This recipe is designed to be flexible, so feel free to substitute ingredients based on what you have on hand or your personal preferences.

* **Udon Noodles:** The star of the show! Look for pre-cooked udon noodles in the refrigerated section of your grocery store or dried udon noodles that you’ll need to cook separately. Choose thick, chewy udon noodles for the best texture.
* **Tofu:** Firm or extra-firm tofu works best in this recipe. Pressing the tofu removes excess water, allowing it to absorb more flavor and become crispy when pan-fried or baked. We recommend extra-firm tofu for its dense texture.
* **Vegetables:** This is where you can get creative! Some of our favorites include:
* **Mushrooms:** Shiitake, cremini, or oyster mushrooms add an earthy umami flavor.
* **Carrots:** Thinly sliced or julienned carrots add sweetness and color.
* **Bok Choy:** This leafy green adds a slightly bitter and refreshing flavor.
* **Spinach:** A great source of iron and vitamins, spinach wilts quickly and easily into the soup.
* **Broccoli:** Adds a nice crunch and texture to the soup.
* **Snow Peas:** Offer a sweet and crisp element.
* **Edamame:** Shelled edamame adds protein and a pop of color.
* **Bell Peppers:** Sliced bell peppers provide sweetness and a vibrant color.
* **Aromatics:** These are the foundation of the flavor of your soup.
* **Garlic:** Minced garlic adds a pungent and savory flavor.
* **Ginger:** Freshly grated ginger adds warmth and a slightly spicy kick.
* **Green Onions:** Both the white and green parts are used. The white parts are sautéed for flavor, while the green parts are used as a garnish.
* **Broth:** Vegetable broth is the base of the soup. Use a low-sodium broth to control the saltiness of the final dish. You can also use homemade vegetable broth for an even richer flavor.
* **Soy Sauce or Tamari:** Adds umami and saltiness. Use tamari for a gluten-free option.
* **Sesame Oil:** Toasted sesame oil adds a nutty aroma and flavor.
* **Rice Vinegar:** Adds a touch of acidity to balance the flavors.
* **Sriracha or Chili Garlic Sauce (Optional):** For a spicy kick.
* **Sesame Seeds (Optional):** For garnish.
* **Other Optional Add-ins:** Seaweed flakes (nori), bean sprouts, corn, water chestnuts, bamboo shoots.

## Step-by-Step Instructions

Now, let’s get cooking! Follow these simple steps to create your delicious vegan udon noodle soup.

**1. Prepare the Tofu:**

* **Press the Tofu:** This step is crucial for achieving crispy tofu. Wrap the tofu in paper towels and place a heavy object (like a cast-iron skillet or a stack of books) on top for at least 30 minutes to remove excess water. The longer you press it, the crispier it will become. You can also use a tofu press if you have one.
* **Cut the Tofu:** Cut the pressed tofu into cubes, slices, or any shape you prefer. Smaller pieces will cook faster.
* **Marinate the Tofu (Optional):** For extra flavor, marinate the tofu in a mixture of soy sauce (or tamari), sesame oil, and a pinch of ginger for about 15-20 minutes. This step is optional, but it will enhance the flavor of the tofu.
* **Cook the Tofu:** There are several ways to cook the tofu:
* **Pan-Frying:** Heat a tablespoon of oil in a non-stick skillet over medium-high heat. Add the tofu and cook for 5-7 minutes, flipping occasionally, until golden brown and crispy on all sides. Don’t overcrowd the pan; cook in batches if necessary.
* **Baking:** Preheat your oven to 400°F (200°C). Toss the tofu with a little oil and spread it in a single layer on a baking sheet. Bake for 20-25 minutes, flipping halfway through, until golden brown and crispy.
* **Air Frying:** Preheat your air fryer to 375°F (190°C). Place the tofu in the air fryer basket in a single layer. Air fry for 10-12 minutes, flipping halfway through, until golden brown and crispy.

**2. Prepare the Vegetables:**

* Wash and chop all the vegetables according to your preference. Slice mushrooms, carrots, and bell peppers thinly. Chop bok choy and spinach into smaller pieces. Mince the garlic and ginger. Slice the green onions, separating the white and green parts.

**3. Sauté the Aromatics:**

* Heat a tablespoon of oil (vegetable or sesame oil) in a large pot or Dutch oven over medium heat. Add the white parts of the green onions, garlic, and ginger. Sauté for 1-2 minutes, or until fragrant, being careful not to burn the garlic.

**4. Build the Broth:**

* Pour in the vegetable broth and bring it to a simmer. Add soy sauce (or tamari), rice vinegar, and sesame oil. Taste and adjust the seasoning as needed. You can add more soy sauce for saltiness, rice vinegar for acidity, or sesame oil for flavor. If you like it spicy, add sriracha or chili garlic sauce to your desired level of heat.

**5. Add the Vegetables:**

* Add the harder vegetables, such as carrots, mushrooms, and broccoli, to the broth. Cook for 3-5 minutes, or until they are slightly softened.
* Add the softer vegetables, such as bok choy, spinach, and snow peas, to the broth. Cook for 1-2 minutes, or until they are wilted.

**6. Add the Udon Noodles and Tofu:**

* Add the udon noodles to the broth and cook according to the package directions. Usually, fresh udon noodles only need a minute or two to heat through, while dried udon noodles may take a bit longer. Be careful not to overcook the noodles, as they can become mushy.
* Add the cooked tofu to the soup and heat through. It’s best to add the tofu at the end to prevent it from becoming soggy.

**7. Serve and Garnish:**

* Ladle the soup into bowls. Garnish with the green parts of the green onions and sesame seeds. You can also add other toppings like seaweed flakes (nori) or a drizzle of sesame oil.

## Tips and Variations

* **Make it Gluten-Free:** Use gluten-free udon noodles and tamari instead of soy sauce.
* **Add More Protein:** Add edamame, chickpeas, or other beans for extra protein.
* **Make it Spicy:** Add more sriracha or chili garlic sauce, or use a pinch of red pepper flakes.
* **Use Different Vegetables:** Feel free to experiment with different vegetables based on what you have on hand or your preferences. Some other great options include bean sprouts, corn, water chestnuts, and bamboo shoots.
* **Make it Ahead:** You can prepare the broth and vegetables ahead of time and store them in the refrigerator for up to 3 days. When you’re ready to serve, simply reheat the broth, add the noodles and tofu, and garnish.
* **Use Different Noodles:** If you don’t have udon noodles, you can use other types of noodles, such as ramen, soba, or rice noodles.
* **Add a Creamy Element:** For a richer and creamier soup, stir in a tablespoon of coconut milk or cashew cream at the end.

## Serving Suggestions

This Vegan Udon Noodle Soup is a complete meal on its own, but you can also serve it with:

* **Steamed Edamame:** A simple and healthy appetizer.
* **Spring Rolls:** Fresh spring rolls filled with vegetables and rice noodles.
* **Seaweed Salad:** A refreshing and flavorful side dish.
* **Kimchi:** Adds a spicy and fermented kick.

## Storing Leftovers

* Store leftover soup in an airtight container in the refrigerator for up to 3 days. The noodles may absorb some of the broth, so you may need to add a little extra broth when reheating.
* It’s best to store the noodles separately from the broth if you plan to keep the soup for more than a day, as the noodles can become mushy over time. Reheat the broth and noodles separately before combining them.
* The soup is not suitable for freezing, as the noodles will become mushy when thawed.
