Heat the oil in a large pot on medium heat. Sauté the onions and ginger until the onions are translucent, about 5-7 minutes.
Add in the mushrooms and cook for about 5 minutes or until they start to cook down and release their water.
Add in the garlic, sliced chili peppers and cook for 1-2 minutes or until the garlic is fragrant. Then add in the red curry paste and mix well. Cook for another 1-2 minutes while stirring occasionally.
Add in the vegan "chicken" broth or vegetable broth and the coconut milk, mix well. Turn the heat down to medium low and simmer the soup until heated through. About 10-15 minutes.
While the soup simmers, cook the noodles according to package directions. Make sure to rinse with cold water to stop them from over cooking. Set aside.
Add in the brown sugar, vegan fish sauce, lime juice and chopped cilantro and mix well. Continue to simmer for another 5-7 minutes.
Assemble each bowl with a portion of noodles and baked tofu. Top each bowl Thai basil, chopped cilantro, sliced chilis sliced green onions and lime wedges.
To Make the Baked Tofu
Cut the tofu into 1”cubes and toss with the garlic powder, onion powder, salt and pepper.
Lay the tofu onto a lined baking sheet in a single layer. Bake at 365 for 12 minutes.
Flip and bake for another 10-12 minutes. Tofu should be nicely browned and have a light crust outside with a soft interior. Set aside.
Red Thai Chili paste can vary in level of heat. I used Thai Kitchen brand but I recommend tasting whichever brand you use and adjust accordingly.
Vegan Fish sauce really gives the soup its flavor. It has become easier to find in stores or online. Here are three brands to look for: 24Vegan, Ocean’s Halo & Au Lac. Alternatively, you could sub 1 Tbsp (15ml) Coconut Aminos or look for Yondu umami seasoning.
Chilis vary in heat. Removing the seeds will help tame them a bit. I used a red chiliwhich is medium spicy. You could also choose a Fresno Chili or for more intense heat go for a Red Thai Chili pepper. Alternatively, if you prefer no spice, use 1/2 small RedBell Pepper, chopped.
The prep and cook times refer to the Thai Red Curry Noodle Soup, not the baked tofu. You can, however, make the tofu at the same time.
