This is the hawker-style vegetarian dinner that turns one head of cauliflower into a glossy, peppery, addictively saucy main. Crispy fried florets coated in a buttery soy-oyster-cracked-pepper sauce, then twirled over spaghetti. Thirty-five minutes, restaurant-quality, easy to make vegan. Cheap, filling, and exactly the kind of spicy-Asian-noodle dinner that's all over food blogs right now.
Fun fact: "Singapore black pepper" sauce was made famous by Singapore's hawker stalls in the 1970s, originally for chili crab. The sauce — heavy on cracked Sarawak black pepper, oyster sauce, and butter — is now used on everything from prawns to chicken to (here) crispy cauliflower. Pairing it with spaghetti instead of rice is the trendy 2020s twist that turned this into a Pinterest hit.
Why this recipe works
- DOUBLE-FRY for true crisp. First fry cooks the cauliflower through; second fry crisps the exterior. Once-fried cauliflower goes soggy under the sauce.
- CRACK YOUR OWN PEPPER. Pre-ground pepper is dust. Coarsely cracked whole peppercorns are what makes black pepper sauce taste like black pepper.
- TOSS, DON'T SIMMER. Combine spaghetti + sauce + cauliflower in 30 seconds off heat. Simmering kills the crisp and the sauce slides off.

Pro tips for the best singapore black pepper cauliflower spaghetti
- BE GENEROUS with pepper. If 2 tbsp seems like a lot, you're right. That's the recipe. Use less if you must but you'll wonder why the sauce tastes flat.
- Make it VEGAN. Use vegan oyster sauce (mushroom-based, widely available) and skip the butter for vegan butter. Tastes identical.
- Add PROTEIN. Drop in cubes of crispy fried tofu or seared shrimp at the same time you add the cauliflower.
- Spice level. Add 1-2 sliced red chilies with the garlic if you want spicy. The dish is heat-mild as written — peppery, not burning.
Frequently asked questions
Can I use frozen cauliflower?
No — it has too much water and won't crisp. Buy fresh.
Can I bake the cauliflower instead of frying?
Yes — toss coated florets with 3 tbsp oil, bake at 425°F (220°C) for 25 min flipping halfway. Won't be as crispy but works.
How spicy is this?
Peppery and warming, not burning. The heat is from black pepper, not chili.
Can I use different pasta?
Yes — fettuccine, lo mein, or even ramen noodles all work. Avoid stuffed pasta or anything with strong flavors of its own.
How do I store leftovers?
2 days fridge but the cauliflower softens fast. Best fresh. Reheat in air fryer at 375°F (190°C) for 5 min to re-crisp.
