Crumble the tofu into a large bowl. Add the Japanese BBQ sauce, garlic powder, cornstarch, salt, and pepper. Toss well until the tofu is evenly coated.
Transfer the tofu to an air fryer tray in an even layer. Air fry at 400 degrees for 15 to 18 minutes, stirring halfway through, until golden and crispy on the edges.
To make in the oven, preheat your oven to 425 degrees. Line a baking sheet with parchment paper and spread the tofu out in an even layer. Bake for 25 to 30 minutes, flipping halfway through, until crispy and lightly browned on the edges.
While the tofu cooks, warm 1 tbsp of avocado oil in a large soup pot or saucepan over medium heat. Add the garlic, ginger, and red curry paste, and cook for 1 to 2 minutes, stirring often, until fragrant and slightly deepened in color.
Add the peanut butter, soy sauce, rice vinegar, and brown sugar directly to the pot. Stir for 30 to 60 seconds until everything becomes glossy and well combined.
Pour in the coconut milk and broth, whisking continuously so the peanut butter fully dissolves into the broth. Bring to a gentle simmer and cook for 5 minutes.
Add the uncooked noodles and continue simmering for about 3 more minutes, or until the noodles are fully cooked and tender.
Remove from the heat and finish with a squeeze of fresh lime juice. Taste and adjust with more salt or lime juice as needed.
Divide the ramen into bowls and top with the crispy tofu, chili crisp, fresh cilantro, and sliced green onions. Enjoy!
