How to Make Spicy Cauliflower Stir-Fry Recipe
Step 1: Prepare Your Vegetables
Start by chopping a medium head of cauliflower into small, bite-sized florets. Slice up a red bell pepper and half a red onion thinly. Mince two garlic cloves and grate a teaspoon of fresh ginger. Having everything prepped ensures your cooking flows smoothly and everything gets cooked just right.
Step 2: Cook the Cauliflower
Heat one tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the cauliflower and cook it for 5 to 7 minutes, stirring occasionally. You want it to soften slightly and develop a bit of golden-brown caramelization — this step brings out a wonderful nutty flavor and a pleasing texture.
Step 3: Add Bell Pepper and Onion
Next, toss in the sliced red bell pepper and red onion. Stir-fry for another 3 to 4 minutes until the vegetables soften just enough to be tender but still retain their fresh crunch, creating an ideal balance in each bite.
Step 4: Stir in Garlic and Ginger
Add the minced garlic and grated fresh ginger to the pan. Cook for one more minute, stirring continuously so their fragrant, spicy aromas infuse the entire dish without burning — this step really elevates the flavor profile of your Spicy Cauliflower Stir-Fry Recipe.
Step 5: Mix and Add the Sauce
In a small bowl, whisk together the soy sauce, sriracha, rice vinegar, and sesame oil. Pour this sauce over the veggies and toss everything well to coat evenly. The combination of salty, spicy, tangy, and nutty tastes is exactly what brings this stir-fry alive.
Step 6: Thicken the Sauce
Finally, stir in the cornstarch slurry—a mix of one teaspoon cornstarch with two teaspoons water. Cook for an additional 1 to 2 minutes while stirring, allowing the sauce to thicken and cling beautifully to the cauliflower and vegetables. Remove from heat once glossy and luscious.
Step 7: Garnish and Serve
Top your stir-fry with sliced green onions and, if you like, sprinkle a teaspoon of sesame seeds for both texture and visual appeal. Your Spicy Cauliflower Stir-Fry Recipe is now ready to enjoy.

Freezing
This Spicy Cauliflower Stir-Fry Recipe freezes well if you want to batch cook. Cool completely before transferring to freezer-safe containers. It will keep for up to 2 months — just thaw in the fridge overnight before reheating.
Reheating
Reheat gently on the stovetop over medium heat, stirring occasionally to avoid drying out. You can add a splash of water or soy sauce if the sauce has thickened too much. Microwave reheating works fine too; cover loosely and heat in short bursts.
