Bangers and mash also known as sausages and mashed potatoes is traditionally a hearty and comforting dish. This lighter, cleaned up version uses a simple homemade gravy and mashed cauliflower to make it low-carb, paleo, and whole30 compliant.
Updated 2019 with Instant Pot instructions
I’m making this because St. Patrick’s Day is coming up. BUT after doing a bit of research, I’m finding that it’s not actually a traditional Irish recipe. That’s okay, I’m still rounding out my St. Patrick Day’s recipe collection with this one. My sausages were uncooked. I pre-browned them in a skillet first. It you’re using uncooked sausage (rather than smoked), I suggest you take the time to brown them first if you’re using the slow cooker. For pressure cooker, it’s listed as a required step.
I used the homemade gravy from my Slow Cooker Beef Tips & Gravy (Paleo/Whole30) recipe. It’s simple, compliant, and full of flavor; the perfect gravy to simmer the bangers and onions in all day. The arrowroot/water slurry is used as a thickener. Using it will make the consistency more of a traditional gravy. If you have a preferred thickener that’s not arrowroot flour/starch, you can swap it in.
Mashed cauliflower or mashed potatoes? I used mashed cauliflower. I was going to used mashed white sweet potatoes but I wanted this recipe to be low-carb as well so I went with cauliflower. For the slow cooker, steam the cauliflower using your preferred method. When I used fresh cauliflower with this recipe, I steam them in my food steamer. When I use frozen cauliflower (yes of course I use frozen vegetables), I pop it in the microwave.
For the pressure cooker, if you have the steamer basket and stand accessories, you can steam the cauliflower directly in the pressure cooker (Instant Pot).
Mash the cauliflower using your preferred method. I use a food processor but other options include a blender or a potato masher.
I’ll let you in on my secret to make them fluffy each time – don’t use any liquid. That’s right, when it’s time to mashed the cauliflower down, I don’t use any liquid. No almond milk, no water, nada. Cooked cauliflower will release enough liquid in the food processor so I just add ghee (butter), salt and pepper. Of course, you can use your preferred mashed cauliflower recipe.

Cook the cauliflower your preferred way. I steam mine. I like to throw the steamed, drained cauliflower (careful, it will be hot) in the food processor with the ghee, salt, and pepper but you can also use a blender, immersion blender, potato masher, etc. Whatever works for you.
