Tender and crisp green beans are an easy and nutritious side dish that can pair with almost any main course! And when you find yourself busy using the stovetop and oven for large family holiday gatherings, having the slow cooker prepare an extra dish in the background sums up my definition of convenience!

But why plain green beans instead of classic Southern-style green beans or crack green beans, you may ask?! Omitting the bacon instantly reduces the total calories in this vegetable side dish and offers a vegan-friendly option. Plus, it’s every bit as tasty!

Slow Cooker Green Beans Recipe

The trick to mouth-watering slow cooker green beans is in the preparatory step of sautéing the subtly sweet yellow onion with olive oil and minced garlic in a heated skillet. This umami mixture is then added to the pot with the green beans, broth, and seasoning – left to cook slowly while all the flavors meld. 

The tender and juicy green beans still have a slightly crisp texture once cooked and an inviting bright green color to add a pop of vibrancy to your dinner table. 

While I love the simplicity of these slow cooker green beans, I’ve also added some ways that you could adapt this side dish to suit your flavor and dietary preferences. Yes, yes, I’ve even included bacon as an option!

ingredients to make slow cooker green beans.

Ingredients For Slow Cooker Green Beans

See recipe card below this post for ingredient quantities and full instructions.

  • Olive oil
  • Onion – I use yellow onion in this recipe for subtle sweetness, but you can use white onion instead. Sauté the diced onion with minced garlic and olive oil before adding it to the slow cooker for a deeper flavor. 
  • Garlic – Two cloves of garlic equal about two teaspoons of minced garlic.
  • Fresh green beans – Placing the green beans in the slow cooker pot in the same direction will help them cook evenly. Fresh green beans are the best for this recipe, but you can use frozen green beans instead. Just keep in mind that they’ll likely take a little longer to cook.
  • Canned chicken or vegetable broth – I recommend low-sodium broth. However, water can be used in a pinch. 
  • Garlic salt
  • Salt and black pepper
  • Nonstick cooking spray


  • Use leftover oven-cooked bacon. Or, cook diced bacon separately in a skillet with heated oil or butter, and toss it into the cooked green beans immediately before serving for a Southern twist. 
  • Add a kick of heat to this dish by including paprika, ground cayenne pepper, or crushed red pepper flakes. 
  • Make this recipe strictly vegan by using vegetable broth instead of chicken broth. 
  • Keep the green beans long for a sophisticated presentation or cut them in half.
  • Garnish with chopped almonds for extra crunch.

How to Make Slow Cooker Green Beans

  1. Prepare the slow cooker: Spray the inside of the pot with nonstick cooking spray. 
  2. Saute the onion: Add the onions, oil, and garlic to the skillet, and sauté until the onions are tender and translucent.
  3. Combine the ingredients: Add the onion mixture, trimmed green beans, broth, and seasoning in the slow cooker and stir to combine. 
  4. Cook the green beans: Secure the lid, and cook on low for 4-5 hours for tender and flavorful beans. Serve the green beans hot.

Quick Tip

Your green beans are fresh if they make an audible sound when snapped in half!

How to Store Slow Cooker Green Beans

Store these slow cooker green beans in an airtight container in the fridge for 3–4 days. Make extra as an easy side dish for days to come, and reheat them in the microwave or on the stovetop.

Serving Suggestions

This incredible vegetable side dish can be enjoyed alongside any kind of main meal. Some of my favorite pairings include this Southern Meatloaf, Roast Turkey, and Roasted Pork Tenderloin. The possibilities are endless! 

Leftovers could even be used up to make this Cheesy Mushroom and Onion Green Bean Casserole!


Do you need to boil green beans before slow cooking?

No. The slow cooker will soften the green beans enough while still leaving a slightly crisp texture. For softer green beans, simply extend the cooking time.

Can you use frozen green beans?

Yes! Frozen green beans will likely require a little extra cooking time as they take longer to heat through.

Can you use canned green beans?

I don’t recommend using canned green beans since they’re already cooked and only require minimal heating time. Canned green beans will become overly soft and mushy if you use them in this recipe without substantial cooking time and ingredient adjustments.

How long do green beans take to cook?

Two pounds of fresh green beans take about 3 hours to cook on HIGH and 4-5 hours on LOW. This will result in tender yet slightly crispy green beans that are still bright in color.
