There’s a fresh take on takeout — take it out of your slow cooker! This Kung Pao Cauliflower is simple to make in a Crock-Pot, and you can easily swap in seitan, chickpeas, or cubed tofu for the cauliflower to suit your diet.

It’s so easy to make Kung Pao Cauliflower in your slow cooker!

It might sound counterintuitive to make a stir-fry-style dish in a slow cooker, but many recipes that don’t rely on ultra-quick-cooking vegetables convert beautifully to low-and-slow. This version uses robust vegetables and a flavor-packed sauce that develops in the crockpot, so you get depth of flavor with hands-off cooking time.

This Kung Pao recipe is from the revised edition of the cookbook The Vegan Slow Cooker. The book includes over a hundred plant-based recipes designed for the slow cooker or Instant Pot, with expanded options for oil-free and gluten-free diets to make the collection more inclusive.

Other favorites from the same collection include cabbage steaks, mushroom congee, and hearty slow-cooker curries. These recipes showcase how versatile slow cooking can be for vegan and plant-based meals.

Is Kung Pao vegan?

Traditional Kung Pao is often presented as Kung Pao chicken, a spicy stir-fry featuring cubed chicken. Vegan adaptations replace the chicken with tofu, tempeh, seitan, or vegetables like cauliflower. Kung Pao Cauliflower offers that same balance of savory, sweet, and tangy flavors while keeping the dish plant-based.

How can I make this gluten-free?

For a gluten-free version, swap regular soy sauce for gluten-free tamari or coconut aminos. Also check the vegan bouillon you use to ensure it’s gluten-free.

Is this Slow Cooker Kung Pao oil-free?

The recipe includes sesame oil for finishing, but you can omit it to make the dish oil-free. If you want a sesame flavor without added oil, sprinkle toasted sesame seeds on top (omit seeds if necessary for allergies).

What can I use in place of cauliflower?

Cauliflower is the featured vegetable here, but you can substitute seitan (if you tolerate gluten), canned chickpeas (drained and rinsed), pressed and cubed firm tofu, or cubed tempeh. In a pinch, hearty potatoes or sweet potatoes would also work and give a different but delicious texture.

Why use cauliflower?

Cauliflower is high in fiber and B vitamins and contains antioxidants and phytonutrients that support overall health. Its fiber content helps digestive regularity and can support weight management, while choline in cauliflower contributes to brain health and memory. Beyond nutrition, cauliflower’s neutral flavor makes it a versatile base for bold sauces.

Some great ideas to make with cauliflower

Cauliflower can be fried, roasted, mashed, or pulsed into “rice.” It works well in soups, casseroles, salads, and sandwiches. Popular plant-based cauliflower dishes include cauliflower po’boy sandwiches and potato-cauliflower curries. You can also experiment by swapping cauliflower into favorite recipes for a nutritious twist.

Is Kung Pao sweet?

Kung Pao sauce balances sweet, salty, and tangy flavors with a mild to moderate heat. Typical ingredients create that mix—soy or tamari, vinegar, a touch of sweetener, and chili for heat—resulting in a rich, brownish sauce that complements the vegetables and protein substitutes.

What is Kung Pao Sauce made of?

Classic Kung Pao sauce and marinades often include soy sauce or tamari, a savory broth (for vegan versions use vegetable or vegan chicken-flavored bouillon), rice vinegar, cornstarch to thicken, and chili paste or red pepper flakes. Szechuan peppercorns are sometimes used to add a unique numbing heat, but they are optional depending on your preference.

Kung Pao Cauliflower: Ingredients You’ll Need

When making this dish, focus on three main groups: the sauce (the flavor foundation), the vegetables and main components that cook in the slow cooker, and the finishing items that thicken and garnish the dish before serving.

For the Sauce

• 3 garlic cloves, minced
• 1 tablespoon grated ginger
• 1½ cups water
• ¼ cup soy sauce or gluten-free tamari (or coconut aminos)
• ¼ cup seasoned rice vinegar or plain rice vinegar mixed with 1 teaspoon sweetener
• 2 tablespoons vegan chicken-flavored bouillon or vegetable bouillon
• ¼ to ½ teaspoon red pepper flakes (adjust to taste)

For the Slow Cooker

• 1 bell pepper, cored and diced
• 5 ounces mushrooms, diced
• 1 can (8 ounces) water chestnuts, drained and diced
• 1½ cups cauliflower florets (or 12-ounce package seitan, or 1½ cups chickpeas or pressed tofu)

Before Serving

• 2 to 3 tablespoons cornstarch (for thickening)
• 2 tablespoons sesame oil for finishing (omit for oil-free)
• Steamed rice, for serving
• Chopped peanuts for topping

How to Make Kung Pao Cauliflower Using Your Slow Cooker

This is a hands-off weekday hero: most prep can be done the night before, making morning assembly quick and leaving the slow cooker to do the rest. The recipe times below are flexible—cook on low for long, then thicken and finish near serving time.

The Night Before

Combine all sauce ingredients and store in an airtight container in the refrigerator. Chop and store the bell pepper, mushrooms, water chestnuts, and cauliflower (or your chosen protein substitute) in a separate airtight container in the fridge.

In the Morning

Place the sauce, vegetables, and cauliflower (or substitute) into the slow cooker. Cook on low for 7 to 9 hours, or on high for a shorter time if preferred. The long, slow cook allows flavors to meld and vegetables to become tender without losing texture.

30 Minutes Before Serving

Raise the slow cooker to high. Stir a slurry of cornstarch mixed with a few tablespoons of the sauce from the slow cooker, then add it back and allow the sauce to thicken for 20–30 minutes. Just before serving, stir in the sesame oil if using. Serve over steamed rice and finish with chopped peanuts for crunch.

Enjoy this flavorful, easy, and versatile plant-based take on Kung Pao—perfect for weeknights and meal prep.
