Preheat oven to 425°F. Line a baking sheet with parchment paper.
In a large bowl, whisk together flour and paprika. Gradually pour in soy milk while whisking. Continue whisking until a smooth batter forms.
Add cauliflower florets and toss to coat the cauliflower with the batter. Spread cauliflower out on prepared baking sheet, trying not to let them touch. Bake for 25 minutes.
Meanwhile, prepare the sauce. In a large bowl, mix gochujang, ketchup, sugar, soy sauce, vinegar, and garlic. Stir until well combined, then add oil and mix again.
Add the cooked cauliflower to the sauce and toss until well coated. Spread the cauliflower out on the baking sheet again and bake another 15 minutes.
Serve immediately, optionally garnished with sesame seeds and/or green onions!
Notes
1) Make it Gluten-Free: Use a gluten-free all purpose flour blend*, or you can try rice flour or buckwheat flour. Use tamari instead of soy sauce. Some gochujang contain wheat so check the ingredients. I like this gluten-free gochujang*.
