Slow-Cooker Kung Pao Beef: This Easy Recipe Is Sweet, Tangy & Way Cheaper Than Takeout

Making this dish in the slow cooker takes 10 minutes to prep, plus cleanup is a breeze!

Takeout is super convenient, but all those to-go orders can add up to a pretty penny. But spending less on takeout shouldn’t mean ditching those weekly favorites entirely. Instead, whip out your slow cooker and make a classic dish like kung pao beef right at home! This appliance does all the work of cooking the beef, vegetables and other ingredients until they’re sweet, spicy and tangy. Even better, this method doesn’t require tons of oil or cleanup afterwards. Just set aside 10 minutes to prep the ingredients for the slow cooker. Then, give this DIY takeout dish time to cook before serving it over a bed of rice or salad. Here’s how to make slow cooker kung pao beef so you can get your takeout fix without breaking the bank!

What is kung pao beef?

Kung pao beef is a stir-fried dish consisting of thin sliced beef, vegetables, chili peppers, peanuts and sauce. It’s a variation of kung pao chicken, a centuries-old dish from the Sichuan province of China. The combination of ingredients in kung pao beef produces a dish that’s sweet and sour, with a noticeable spiciness. Although it’s often cooked in a wok or skillet, using the slow cooker is an alternative option that doesn’t involve standing over a hot stove.

How the slow cooker helps create tasty kung pao beef

The gentle heat from a slow cooker helps break down the beef’s fibers, which produces tender meat. Similarly, the heat gradually cooks vegetables so they’re soft but still maintain a slight firmness. Ingredients within the sauce like soy sauce and garlic also have a chance to meld together and infuse the entire dish with delicious flavors.

Chef’s #1 tip for the best-ever kung pao beef dish

When making kung pao beef in the slow cooker, culinary creator Peter Som suggests letting the meat cook before adding the vegetables. “Remember to add the vegetables at the end of the cooking process so they don’t overcook (overcooking your veg will decrease nutrient levels) and maintain a nice tender crunch,” he says. Vegetables like bell peppers and broccoli are great choices as they’re sweet and earthy. Also, they’re rich in vitamin C and potassium — which help strengthen your immune system, reduce cancer risk and regulate cell function. For maximum flavor and health benefits, add the vegetables during the last 30 minutes of cooking.

This Slow Cooker Kung Pao Beef recipe from Robert Smith, private chef at Culinary Collective ATL, is a toss-together weeknight wonder!

What to serve kung pao beef with

Once cooked, pair your kung pao beef with any of these five delicious sides.

1. Steamed rice

Fluffy white, brown or cauliflower rice is a hearty starch that absorbs the dish’s sweet and savory sauce.

2. Egg or rice noodles

The thick sauce also clings well to rich and filling egg or rice noodles.

3. Shredded vegetable salad

For extra crunch, serve the kung pao beef with a salad full of shredded cabbage, carrots and/or raw onions.

4. Plain fried rice

Serving the dish with fried rice offers a nice combination of salty and nutty flavors.

5. Spring rolls 

Light and crispy spring rolls perfectly contrast the dish’s tender meat and vegetables.
