The key to great ramen is the broth. This vegetarian broth is rich and umami-forward, with a touch of heat from chili garlic sauce. It’s a versatile base you can reuse for many variations, and it only takes a single pot and about 15 minutes to prepare. The recipe is ideal for busy weeknights when you want something quick, comforting and satisfying.

Ingredients

Shiitake mushrooms – about 1/2 pound, sliced. Fresh shiitake are traditional in ramen and provide deep umami. If you can’t find them, use sliced baby bella mushrooms.
Toasted sesame oil – 1 tablespoon. Toasted sesame oil adds a nutty aroma and helps brown the mushrooms; use toasted rather than plain sesame oil for best flavor.
Soy sauce – 2 tablespoons. Use regular, low-sodium or a flavored soy sauce you enjoy; it adds salt and umami to the broth.
Minced garlic – 1 tablespoon, fresh for best flavor.
Chili garlic sauce – 2 teaspoons. Adds gentle heat and garlic flavor; increase to taste for spicier ramen.
Vegetable broth – 4 cups (a standard 32-ounce carton). You can use homemade or store-bought.
Ramen noodles – 6 ounces total (two 3-ounce packages). Discard the seasoning packets; use the noodles only. Choose vegetarian ramen noodles or gluten-free if needed.
Fresh spinach leaves – about 1 cup, added at the end to wilt into the hot broth.

Prepare the mushrooms. Wipe shiitake mushrooms clean with a damp paper towel and slice them into thick pieces.
Brown the mushrooms. Heat 1 tablespoon toasted sesame oil in a large pot or wok over medium-high heat. When the oil is hot, add the sliced mushrooms and 2 tablespoons soy sauce. Stir to combine, then let the mushrooms cook undisturbed for about 5 minutes so they develop a golden color and concentrated flavor.
Build the broth. Add 1 tablespoon minced garlic to the pot and cook 1 minute, stirring briefly. Stir in 2 teaspoons chili garlic sauce and pour in 4 cups vegetable broth. Increase heat to high and bring the mixture to a boil.
Cook the noodles and finish. Once the broth is boiling, add the ramen noodles and make sure they are submerged. Cook for 3 minutes, then stir in the fresh spinach and combine. Turn off the heat and portion the soup into bowls.
Serve with toppings. Top each bowl with your preferred garnishes (see the optional toppings list below) and serve immediately.

Optional toppings

Ramen is best enjoyed with toppings for contrast in texture, heat and freshness. Here are popular ideas to customize each bowl:

Soft boiled egg – slice in half lengthwise. Cook 6 minutes for runny yolk or about 8 minutes for a firmer, medium yolk.
Diced green onions or scallions for brightness.
Fresh cilantro leaves for herbal lift.
Sriracha or extra chili garlic sauce for more heat.
Chili onion crunch or other crunchy chili condiments for texture.
Sesame seeds (black or white).
Chili oil, bean sprouts, nori strips (seaweed) or corn kernels.
Gochujang for a fermented, spicy-sweet boost.

Additions and variations

Miso broth: Stir 1 1/2 tablespoons white miso paste into the broth along with the chili garlic sauce for a richer miso ramen.
Extra heat: Add 4–5 minced Thai chilies when you add the garlic, or add an additional teaspoon of chili garlic sauce or sriracha.
Dried shiitake mushrooms: If using dried shiitake, soak them in hot water for at least 10 minutes, drain, pat dry and use like fresh mushrooms.
Creamy option: Substitute one cup of the vegetable broth with one cup of unsweetened soy milk for a slightly creamier finish.

Diet variations

Vegan: Omit the egg topping to keep the ramen fully vegan. You can also add tofu or a plant-based egg substitute for protein.

Gluten-free: Use certified gluten-free ramen noodles and gluten-free soy sauce (such as tamari). Verify labels on broths and sauces to ensure they are gluten-free.

Storage options

To store: Leftover ramen can be refrigerated up to 7 days when kept in an airtight container.
To reheat: Warm in a pot on the stove over medium-high heat for 5–8 minutes, or heat in a microwave-safe bowl for about 2 minutes. Add a splash of water or extra broth if the soup has reduced.
To freeze: Freezing finished ramen is not recommended because the noodles lose texture. You can freeze the broth separately and add fresh noodles when reheating.
