Slow Cooker Baked Beans | Healthy Freezer-Friendly Recipe

These slow cooker baked beans are one of the recipes I make on repeat. About every four to six weeks I make this big batch, freeze it into four containers and keep one in the fridge ready to go. The recipe below is already my larger batch version, because if I’m going to put in the effort, I want it to last. If you don’t need as much, you can easily halve the recipe. Every morning I spoon out about a third of a cup, warm it up in the microwave and serve it with scrambled eggs and pan-fried mushrooms. It’s one of those breakfasts that keeps me full for hours and makes busy mornings so much easier.

I originally started making baked beans because I wanted to cut back on processed meat and stop relying on bacon for breakfast. The recipe started as the Skinnymixers Smoky Baked Beans recipe, but over the years I’ve adapted it to suit the way we eat now—removing the chorizo, skipping the added sugar, replacing the Worcestershire sauce, adding sweet potato and slow cooking it instead. These days it’s become one of those recipes I genuinely don’t like running out of.

If you’re looking for thick, flavour-packed slow cooker baked beans that are healthier than supermarket versions, these homemade baked beans are perfect for meal prep and easy to adapt for different dietary needs.

These baked beans have become one of those recipes I hardly have to think about anymore. They’re simple to make, freeze beautifully and save me time on busy mornings. Best of all, they’re easy to adapt depending on what you’ve got in the pantry or the dietary needs you’re cooking for.

Why This Slow Cooker Baked Beans Recipe Works

Ingredients

Here’s everything you need to make these Slow Cooker Baked Beans at home.

⚠️ Batch size note: This recipe makes a large batch of homemade baked beans because it’s designed for meal prep and freezing. I make this quantity every four to six weeks and freeze portions for easy breakfasts. If you prefer a smaller batch, simply halve all ingredients.

• 1 medium brown onion, roughly chopped – Adds sweetness and depth as it slowly cooks. Onion also provides prebiotic fibre that help support gut health. If you need a low-FODMAP option, use the green tops of spring onion or garlic-infused oil instead.
• 6 cloves garlic, minced – Adds savoury flavour and richness. Garlic is part of the flavour base that gives these beans that slow-cooked taste. For a low-FODMAP option, swap for garlic-infused oil.
• 2 × 400g tins chopped tomatoes – Creates the rich tomato base for the sauce and adds natural acidity that balances the sweetness of the sweet potato. Use your preferred canned tomatoes — I usually choose brands with simple ingredients.
• 100g tomato paste – Adds concentrated tomato flavour and helps create a thick, rich sauce. Tomato paste is one of those simple ingredients that makes a big difference in slow cooker recipes.
• 2 tbsp balsamic vinegar – Replaces the tangy depth usually provided by Worcestershire sauce. It adds acidity, a subtle sweetness and helps balance the richness of the beans.
• 2 tsp Dijon mustard – Adds a little sharpness and extra savoury flavour without making the beans taste like mustard. Check your brand if you need the recipe to be gluten free.
• 2 tsp Vegemite (optional but highly recommended) – Adds a deep savoury umami flavour that replaces the richness you would normally get from meat or Worcestershire sauce. Regular Vegemite is not gluten free, so use Gluten Free Vegemite if needed.
  • No Vegemite? Replace with:
  • 1 extra tablespoon tomato paste
  • 1 teaspoon balsamic vinegar
  • extra pinch of salt
    ⚠️ Note: Regular Vegemite contains gluten, so it is not suitable for coeliac diets.
• 2 tsp smoked paprika – Adds the smoky flavour traditionally associated with baked beans. It gives the recipe depth without needing bacon or chorizo.
• 1 tsp salt – Enhances all the flavours and balances the acidity from the tomatoes. Adjust to taste depending on your canned beans and personal preference.
• Pinch black pepper – Adds a gentle warmth and balances the sweetness of the sweet potato.
• 2 cups diced sweet potato – This is one of my favourite additions to this recipe. Sweet potato naturally thickens the sauce, adds gentle sweetness without added sugar, and provides fibre, vitamins and minerals.
  • You can swap this for:
  • pumpkin
  • carrot
  • a combination of both
• 4 × 400g tins cannellini beans – The star ingredient! Cannellini beans provide plant-based protein and fibre, making these baked beans filling and satisfying. You could also use butter beans or a combination of both.
  • For the best texture:
  • Drain and rinse 2 tins
  • Leave 2 tins undrained
    
    The bean liquid helps create a thick, creamy sauce without needing extra water.
• Gelatin or collagen powder (optional) – I add this for extra protein and gut-friendly benefits. It doesn’t significantly change the flavour but can add nutritional value.
  ⚠️ Important: Add gelatin or collagen only once the beans are hot. Adding gelatin too early can cause it to bloom and form lumps instead of dissolving smoothly.

💡Tip: Leaving two tins undrained gives the beans a thicker, creamier sauce without needing to add water. However, if you are like me and forget this step, 300g of water instead will work fine. You may just need to add more salt.

Step-by-Step Instructions

These slow cooker baked beans take just a few minutes to prepare before the slow cooker does the rest.

Slow Cooker Method

1. Add the onion, garlic, tomatoes, tomato paste, balsamic vinegar, Dijon mustard, Vegemite, smoked paprika, salt, pepper and sweet potato to the slow cooker.
2. Add two drained tins of cannellini beans and two undrained tins.
3. Stir everything together.
4. Cook on LOW for 6–8 hours or HIGH for 3–4 hours. The sweet potato should be very soft and the sauce should have thickened.
5. Taste and adjust the seasoning if needed.
6. If using gelatin or collagen, wait until the beans are fully heated before stirring it through. Adding gelatin too early can cause it to bloom and form lumps.

💡Tip: Place the slow cooker outside (undercover) to prevent your house from smelling. While they taste amazing, I admit the smell while cooking is not my favourite.

Pantry Notes

These swaps help you adapt the recipe depending on what you have available.

• Butter beans also work well.
• Add chilli flakes if you like a little heat.
• Add diced carrot instead of sweet potato.
• Smoked salt adds even more smoky flavour.
• A splash of apple cider vinegar can replace part of the balsamic if you prefer a tangier finish.
