Easy Slow Cooker Southern Collard Greens with Fire Roasted Tomatoes (Meat-Free!)

Collard greens have grown to be one of my favorite vegetables to make! When made correctly, they’re absolutely delicious. I could seriously eat an entire batch of these southern collard greens with fire roasted tomatoes! The tomatoes definitely give them a little extra flavor that’s soooo welcomed!

I’ve made southern collard greens in the past, but never in the slow cooker, so I thought it would be worth trying. Especially with the holidays coming up! I know it’s only August, but Thanksgiving, Christmas and the New Year will all be here before we know it, so we’d better go ahead and get our ducks in a row!

My Crockpot (or slow cooker) is probably one of the most underutilized tools in my kitchen, so I’m trying to change that. I love that with this recipe you can basically set it and forget it! These southern collard greens with fire roasted tomatoes are cooked and ready to serve in two hours and you don’t have to worry about one more thing taking up space on the stove.

How to Wash Collard Greens

I’ll be honest with you, I never really understood why people made such a big deal about washing collard greens. It’s not difficult at all. I’ve always found success washing them just as I would any other vegetable. How you ask? Like this!

First, I wash out my sink with warm water and dish soap, followed by a good rinse of hot water. Next, I fill my sink up with room temperature water (about 1/2-3/4 full) and pour a good amount of apple cider vinegar in. I don’t measure it, but if I had to guess I’d say about 1/4 cup. Now it’s time to add in the greens. I submerge them into the water (they will float back to the top) and let them sit for about 45 minutes to 1 hour.

After the greens are done soaking, I lightly scrub each leaf with a vegetable brush, rinse them one last time with warm water and set them aside.

How to Cut Collard Greens

Cutting the greens to make these southern collard greens with fire roasted tomatoes can be achieved in a variety of ways. I’ve seen people who shred them by hand or even cut them into very narrow slivers. I like to keep things simple and quick! I take each collard green leaf and remove the center stem. I do this by laying the leaf flat and going along the outside of the stem area with a knife. Then I give a final tug to the stem to remove it completely.

From there, I cut the leaf in half and roll it up like a cigar. Then I cut it into about 1/2-1 inch pieces which result in small collard green pinwheels. From here you have the choice of leaving them as is, or cutting the pinwheels in half to create shorter pieces. The choice is yours!

Cooking the Collard Greens in the Slow Cooker (Crockpot)

Cooking these southern collard greens with fire roasted tomatoes in the crockpot is reaaaaally easy! Once all of your ingredients are prepped and measured out, the only thing that you’ll need to do is simply add all of them to the slow cooker and give them a stir so that all of the ingredients are able to combine as the machine heats up.

Tips for Making Easy Southern Collard Greens:

  • Cut up all of your ingredients at the same time (collards and onions)
  • Measure out all of your seasonings at the same time. This way you can dump them all in at once.
  • Don’t forget to plug the crockpot IN! This sounds like a no-brainer, but I definitely did this myself. If your crockpot is like mine (nothing fancy, just basic), it doesn’t have a light or indicator telling you it’s actually on. Because of this, I didn’t realize mine wasn’t on until an hour and a half after “setting” it! Don’t be like me folks!

I know you’ll love these slow cooker southern collard greens with fire roasted tomatoes! They’re super easy to make and flavorful! Your family won’t even know they’re vegan! Give this recipe a try and let me know what you think in the comments below!

    I finally made some collard greens for Thanksgiving! This recipe was easy but full of flavor. I love the kick of spice too! I think I had way more than 2 pounds of greens but we stuffed it in the crockpot and let it cook longer and it was fine. My mom loved them which was the ultimate praise! Will definitely be using this recipe again!
