Ingredients

Ingredient Amount Notes
Collard greens 2 large bunches (about 1.5 lbs) Stems removed, leaves chopped
Yellow onion 1 medium Diced
Garlic 4 cloves Minced
Vegetable broth 4 cups Low-sodium preferred
Canned diced tomatoes 1 (14.5 oz) can With juices
Apple cider vinegar 2 tbsp Adds tang and brightness
Olive oil 2 tbsp For sautéing
Smoked paprika 1 tsp Optional but recommended
Red pepper flakes 1/2 tsp Adjust to taste
Salt 1 tsp Or to taste
Black pepper 1/2 tsp Freshly ground
Bay leaf 1 Optional

Equipment

  • Slow cooker (crockpot) – 6-quart recommended for this volume
  • Cutting board and knife – for prepping vegetables and greens
  • Measuring cups and spoons – for accuracy
  • Large skillet – for optional sautéing
  • Wooden spoon or spatula
  • Colander – to rinse and drain collard greens
  • Ladle – for serving

Instructions

  1. Prepare the Collard Greens:

    Wash the collard greens thoroughly. Remove tough stems, stack the leaves, roll them up, and slice into 1-inch wide ribbons.

    Place the chopped greens in a colander and rinse again if needed.

  2. Sauté Aromatics (Optional but Recommended):

    In a large skillet over medium heat, heat the olive oil. Add diced onion and sauté for 3-4 minutes until translucent.

    Add minced garlic and cook for 1 minute more, until fragrant.

    Sautéing builds a deeper flavor base for your greens, but you can skip this step and add everything straight to the slow cooker if you’re short on time.

  3. Layer Ingredients in the Slow Cooker:

    Add the sautéed onion and garlic to your slow cooker. Top with chopped collard greens, canned tomatoes (with juices), smoked paprika, red pepper flakes, bay leaf, salt, and black pepper.

  4. Add Vegetable Broth and Vinegar:

    Pour in the vegetable broth and drizzle apple cider vinegar over the mixture. Gently toss or press down the greens to ensure even distribution and submersion in the liquid.

  5. Slow Cook:

    Cover and cook on low for 6-8 hours, or high for 3-4 hours. Greens should be meltingly tender, with a savory, brothy base.

    For best results, slow and low is the way to go! This allows the flavors to meld and the greens to become silky soft.

  6. Taste and Adjust:

    Remove the bay leaf. Taste and add more salt, pepper, or vinegar as desired.

    If you like a bit more acidity, a splash of hot sauce at this stage is delicious.

  7. Serve:

    Ladle greens and broth into bowls or serve as a side dish. Enjoy hot, garnished with extra red pepper flakes or a drizzle of olive oil if desired.

Tips & Variations

  • Add Protein: Stir in a can of drained and rinsed white beans, black-eyed peas, or chickpeas during the last hour of cooking for a one-pot meal.
  • Mix Up the Greens: Substitute part of the collard greens with turnip greens, kale, or mustard greens for a unique blend of flavors and textures.
  • Spice It Up: Add chopped jalapeño, a splash of your favorite hot sauce, or a pinch of homemade vegan chili powder for extra heat.
  • Make It Oil-Free: Skip the olive oil and dry-sauté aromatics with a splash of vegetable broth, or simply add onions and garlic raw to the slow cooker.
  • Smoky Notes: If you love a classic Southern smoky flavor, try a few drops of liquid smoke or a sprinkle of smoked salt.
  • Batch Cooking: This recipe doubles well—just make sure your slow cooker can handle the volume!
  • Serving for a Crowd: Easily portable and keeps warm in the slow cooker for potlucks or family gatherings.
